Description

Non-reactive, chlorine-free composition

The present invention relates to non-reactive compositions of A) amorphous poly-α-olefins which contain no organically bound chlorine and have a melting enthalpy in the range of 0 to 80 J / g, B) ketone, ketone / aldehyde and / or urea / Aldehyde resins and / or their hydrogenated derivatives, C) solvents and D) optionally auxiliaries and / or additives and their use as primers to improve the adhesion of coating materials such as paints, coatings, adhesives and sealants, inks and inks Plastics and glass.

It is known that ketones or mixtures of ketones and aldehydes can be converted to resinous products in the presence of basic catalysts or acids. Thus, it is possible to prepare resins from mixtures of cyclohexanone and methylcyclohexanone (Ullmann, Vol. 12, p. 551). The reaction of ketones and aldehydes usually leads to hard resins, which are often used in the paint industry.

Technically important ketone-aldehyde resins are nowadays mostly produced using formaldehyde.

Ketone-formaldehyde resins have been known for a long time. Process for the preparation are for. B. described in DE 102006009080.2 and in the patents cited therein.

For preparation, ketones and formaldehyde are normally reacted with each other in the presence of bases.

Ketone, ketone / aldehyde and / or urea / aldehyde resins and their hydrogenated derivatives are used in coating materials such. B. used as a film-forming additive components to improve certain properties such as drying speed, gloss, hardness or scratch resistance. Because of their relatively low molecular weight, conventional ketone, ketone / aldehyde and / or urea / aldehyde resins and / or their hydrogenated secondary products have a low melt and solution viscosity and therefore serve in coating materials and the like. a. as film-forming functional fillers.

The carbonyl groups of the ketone-aldehyde resins are subject to z. B. irradiation with z. B. sunlight classic degradation reactions such. B. of Norrish type I or II. The use of unmodified ketone-aldehyde or ketone resins is therefore for high-quality applications such. B. outdoors, in which high resistance properties, in particular to weathering and heat are required, not possible. These disadvantages can be improved by hydrogenation of the carbonyl groups. The conversion of the carbonyl groups into secondary alcohols by hydrogenation of ketone-aldehyde resins has been practiced for a long time (DE 870 022).

The preparation of carbonyl- and ring-hydrogenated ketone-aldehyde resins based on ketones containing aromatic groups is also possible. Such resins are described in DE 102006026758.3 or DE 12006026760.5.

Largely amorphous poly-α-olefins have long been known. Catalyst systems which consist of the reaction product of a titanium trihalide with an aluminum compound on the one hand and a titanium oxycarbohydride on the other hand are already described in DE-A-1 442 831. Using this catalyst system, amorphous polyolefin copolymers are obtained.

From DE-A-23 06 667 it is known that largely amorphous poly (I-butene) polymers by the low-pressure polymerization by polymerization of 1-butene, optionally in the presence of other olefins, at temperatures of 40 to 120 ⁰ C in solution with the help of a TiCI ₃ • n AICI ₃ (n = 0.2 - 0.6) mixed contact and a suitable trialkylaluminum.

In DE-A-29 30 108, substantially amorphous 1-butene-propene-ethene terpolymers with a high softening point are prepared in a similar manner, likewise a mixed contact of TiCl ₃ .n AICI ₃ (n = 0.3-0 , 35) and a trialkylaluminum are used as cocatalyst.

DE-A-26 37 990 describes terpolymers which have a propene content of at least 93.2% by weight and an ethene content of not more than 1.9% by weight and a 1-butene content of not more than 4.9% by weight .-% exhibit. Again, a TiCl ₃ mixed contact and a cocatalyst called "activator" are used. None of these applications refers to the use of primer compositions based on poly-α-olefins and ketone, ketone / aldehyde and / or urea / aldehyde resins and / or their hydrogenated secondary products, which has a very good adhesion of Allow coating materials on untreated plastics.

For coating non-polar plastics, these are usually pretreated in order to obtain a sufficiently high adhesion of the coating to the plastic. So z. B. plastics from polyolefins such. Example of polypropylene (PP), modified polypropylene (eg., Polypropylene-ethylene copolymers), polyethylene (PE), modified PE, mixtures such. B. polypropylene / ethylene-propylene-diene blends (PP / EPDM) with low EPDM content, PP / PE blends or special polyester pretreated by certain methods, so that the coating material adheres to the plastic. Typical methods are flaming, corona discharge, gas phase fluorination or plasma treatment. By these methods, the plastic surface is partially oxidized, so that the surface tension increases. This allows subsequent coatings or bonds to the substrate to form intermolecular interactions, thereby improving adhesion. The disadvantages of these methods lie in the high costs and in the fact that the effect of pretreatment decreases over a relatively short period of time (a few days to weeks). In addition, corona-pretreated plastics tend to block, so that this pretreatment method can in principle be done only inline to the application of the coating material.

Other methods, such as As the addition of additives to improve the adhesion during the production of the plastic are also possible. The disadvantages of such methods are the relatively high cost and due to the fact that the low molecular weight additives cause problems in the production of the plastic and the physical properties such. B. can negatively affect the mechanical strength.

Another possibility of pretreatment is the application of primers to the plastic prior to application of the coating material.

US 2003/055163 describes binder compositions which contain, inter alia, chlorinated, COOH-containing polyolefins and ketone resins. JP 46027878 also describes compositions which, in addition to ketone resins, contain chlorinated polyolefins.

Products containing organically bound chlorine, can split off hydrochloric acid and z. B. form highly toxic dioxins. Therefore, such methods are not recommended for reasons of labor and environmental protection.

The object of the present invention was to find compositions based on poly-α-olefins and ketone, ketone / aldehyde and / or urea / aldehyde resins and / or their hydrogenated secondary products, which has a very good adhesion of coating materials allow untreated plastics. The compositions should be free of chlorine and have a rapid drying and high blocking resistance. The effect of the pretreatment should also persist over a long period of time, so that either pretreatment directly after the production of the plastic by the plastic manufacturer (off-line) or pretreatment directly before the application of the coating material (in-line) is possible.

The object underlying the invention is surprisingly achieved according to the claims, by prior to application of the coating material primer compositions based on poly-α-olefins and ketone, ketone / aldehyde and / or urea / aldehyde resins and / or their hydrogenated Subsequent products are applied to the plastic, which are described in more detail below.

In contrast to the prior art, the compositions according to the invention are free of organically bound chlorine. They have a rapid drying and a high blocking resistance. The effect of the pretreatment is also constant over a long period of time.

The compositions according to the invention can therefore be used, in particular for improving the adhesion of coating materials to plastics.

The present invention relates to non-reactive compositions containing no organically bound chlorine, essentially containing A) 1 to 98 wt .-% of at least one non-reactive poly-α-olefin containing no organically bonded chlorine and a enthalpy of fusion in the range of 0 to 80 J / g and B) 1 to 98 wt .-% of at least one Ketone, ketone / aldehyde and / or urea / aldehyde resin and / or its hydrogenated secondary product and

C) 1 to 98 wt .-% of at least one solvent and optionally D) up to 97 wt .-% of at least one auxiliary or additive, wherein the sum of the weights of components A) to D) is 100 wt .-%.

It has been found that the combination of the compositions of components A) to D) described below fulfill all the required criteria.

Component A)

The component A) essential to the invention is used in amounts of from 1 to 98% by weight, preferably from 1 to 49% by weight, particularly preferably from 1 to 40% by weight. In principle, all poly-α-olefins which are soluble and / or swellable in organic solvents are suitable. These poly-α-olefins may carry functional groups by modification (eg with maleic anhydride) or be largely free of functional groups (pure hydrocarbon polymers).

As component A) non-reactive poly-α-olefins are used which contain no organically bound chlorine and have a melting enthalpy in the range of 0 to 80 J / g, which are therefore largely amorphous.

The non-reactive, largely amorphous poly-α-olefin may be a homo- or copolymer, for. Atactic polypropylene (APP), atactic polybutene (1) or preferably a co- and / or terpolymer having the following monomer composition:

From 0.5 to 100% by weight, preferably from 1 to 99% by weight, particularly preferably from 10 to 98% by weight, of one or more α-olefins having from 4 to 20 carbon atoms,

1 to 99.5 wt .-%, preferably 1 to 99 wt .-%, particularly preferably 2 to 90 wt .-% of propene and 0 to 50% by weight, preferably 0 to 20% by weight of ethene,

where the poly-α-olefin

A weight-average molecular weight of from 2,000 to 500,000 g / mol, preferably from 5,000 to 300,000 g / mol, more preferably from 7,500 to 200,000 g / mol,

A polydispersity PD of 2.0 to 60, preferably 2.5 to 40, particularly preferably 2.5 to 30,

• a glass transition temperature Tg of -80 to 0 ⁰ C, preferably from -60 to 0 ⁰ C, more preferably -55 to -10 ⁰ C, • an enthalpy of fusion in the range of 0 to 80 J / g, preferably in the range of 1 to 70 J / g, more preferably in the range of 1 to 60 J / g as well as

• has a high solubility or swellability in non-polar solvents.

The properties of the poly-α-olefins can take on all possible variations within the above values, e.g. B. a PD of 2.5 to 30 (smallest range) and a Tg of -80 to 0 ⁰ C (largest range).

As α-olefin having 4 to 20 carbon atoms, preferred are 1-butene, 1-pentene, 1-hexene, 1-octene, 1-decene, 1-dodecene, 1-octadecene, 3-methyl-1-butene, a methylpentene such as z. For example, 4-methyl-1-pentene, a methylhexene or a methylhepten, alone or in mixture used.

The determination of the molecular weight and polydispersity is carried out by high-temperature GPC. The determination is carried out according to ASTM D6474-99, but at a higher temperature (160 ⁰ C instead of 140 ⁰ C) and a lower injection volume of 150 ul instead of 300 ul. The solvent used is trichlorobenzene. The measurement is carried out at a column temperature of 160 ^° C. The universal calibration used for the evaluation of the elution curves is carried out on the basis of polyolefin standards. The results are not comparable with measurements whose calibrations based on non-related polymers - eg. B. on polystyrene basis - was carried out, or which have been done without universal calibration, otherwise there is an impermissible comparison of different three-dimensional polymer structures or hydrodynamic radii. Also, the comparison with measurements using other than the specified solvent, is not permissible because in different solvents different three-dimensional Polymer structures or hydrodynamic radii may be present, which lead to a different result in the molecular weight determination.

The polydispersity PD is defined as the quotient of number average and weight average molecular weight. In particular, it is a measure of the width of the present molar mass distribution, which in turn allows conclusions to be drawn about the present polymerization behavior and the catalyst used. In addition, it is also a measure of the existing low molecular weight fraction, which in turn has an influence on the adhesion properties of the polymer materials. The polydispersity is characteristic within certain limits for a particular catalyst-cocatalyst combination. The molar mass distribution can be either mono-, bi- or depending on the procedure used (eg 1, 2 or more stirred tank or combinations of stirred tank and flow tube) or reaction (single or multiple dosing of catalyst, cocatalyst and monomers) be multimodal. The polydispersity has a relatively strong influence on the tackiness of the material at room temperature and on the adhesion.

In addition, molecular weight and polydispersity u. a. a strong influence on solution viscosity, mechanical properties and adhesion properties. The lower the molecular weight, the lower the viscosity in solution. However, low molecular weight mechanical properties can be adversely affected. To achieve optimum properties, therefore, the weight-average molecular weight of component A) is between 2,000 and 500,000 g / mol, preferably between 5,000 and 300,000 g / mol, more preferably between 7,500 and 200,000 g / mol, and the polydispersity between 2 , 0 and 60, preferably between 2.5 and 40, more preferably between 2.5 and 30.

The melting enthalpy, the glass transition temperature and the melting range of the crystalline fraction are determined by differential calorimetry (DSC) according to DIN 53 765 from the 2nd heating curve at a heating rate of 10 K / min. The inflection point of the heat flow curve is evaluated as the glass transition temperature. The glass transition temperature can be controlled in a known manner via the monomer composition and the reaction conditions. Generally, the use of longer chain monomers leads to lower glass transition temperatures. Likewise cause reaction conditions in which also form shorter-chain polymers (for example relatively high polymerization temperatures) in a certain scope also to lower the glass transition temperature.

A low glass transition temperature Tg has a positive effect on the (low temperature) flexibility, but has a negative effect on the blocking resistance and a fast drying rate (solvent retention time).

Therefore, the Tg of component A) is chosen so that it is between -80 and 0 ⁰ C, preferably between -60 and 0 ⁰ C, more preferably between -55 and -10 ⁰ C.

The enthalpy of fusion is a measure of the crystallinity of the polymer. The polymers of component A) have a relatively low crystallinity, ie they are largely, but not completely, amorphous. There is a certain crystallinity, which is essential for the required material properties. The detectable during melting crystalline regions extend over a wide temperature range from 0 to 175 ⁰ C and are different in intensity depending on the location. The polymers of component A) are distinguished in their crystallinity by the occurrence of both mono- and bimodal and multimodal melting peaks, some of which are sharply separated, some of which merge into one another. The enthalpy of fusion (as a measure of the total crystallinity) of the polymers of component A) is between 0 J / g and 80 J / g, preferably in the range of 1 to 70 J / g, particularly preferably in the range of 1 to 60 J / g.

The low crystallinity on the one hand high transparency, on the other hand, a special combination of advantageous material properties can be achieved. Low crystalline polyolefins show relatively high surface tack (adhesion) at room temperature. As a result, they have overall a more flexible mechanical behavior. However, the cohesion of such materials is relatively low, which is why these low crystallinities are not generally sought. Due to the higher crystallinity, a special combination of advantageous material properties can be achieved. Inventive polymers with relatively high crystallinities, such. As polybutene or butene copolymers with high butene shares, have z. B. very good tensile strength. At the same time they show a relatively low surface tackiness.

The solubility and / or swellability in non-polar solvents is desirable for the

Component A) can be processed. On the one hand, it should be homogeneously miscible in combination with the components B) to D), on the other hand, the composition from A) to D) with common methods, such. As spraying, printing, casting, brushing or sponge application, be easily applied.

The solubility is determined by dissolving component A) in the respective solvent or solvent mixture in 10 or 50% dilution with stirring

Reflux temperature and then cooling the solution to room temperature. The

Solubility of component A) in xylene is between 80 and 99.9%, preferably between 85 and 99.5% and more preferably between 90 and 99.0%. In addition, the

Component A) soluble in aromatic solvents such. As toluene, benzene, cresols, naphthalene, tetrahydronaphthalene and / or in aliphatic solvents and

Solvent mixtures, such as decahydronaphthalene, hexane, heptane, cyclohexane, crystal oils,

White spirits, turpentine, paraffins alone or in a mixture.

Typical methods of preparation and compositions for preparing the non-reactive, substantially amorphous, poly-α-olefins are e.g. As described in DE 40 00 695, DE 100 31 293 and WO 2006/060648.

Component B)

The component B) essential to the invention is used in amounts of from 1 to 98% by weight, preferably from 1 to 49% by weight, particularly preferably from 1 to 40% by weight.

These products are particularly responsible for a fast drying rate (improved solvent retention) and high blocking resistance. In addition, the use of components B) improves the compatibility with respect to subsequent coating materials in wet-on-wet application and the adhesion of the subsequent coatings to the primer layer. Last but not least, the solubility of component A) of the composition according to the invention is increased by the presence of component B) and the course and the solids content are improved.

Suitable as component B) are ketone, ketone / aldehyde and / or urea / aldehyde resins and their hydrogenated secondary products alone or in a mixture.

In general, all ketones known in the literature as suitable for ketone and ketone-aldehyde resin syntheses, generally all CH-acidic ketones, can be used. Suitable ketones for the preparation of the ketone and ketone-aldehyde resins (component B)) are all ketones, in particular acetone, acetophenone, methyl ethyl ketone, tert-butyl methyl ketone, heptanone-2, pentanone-3, methyl isobutyl ketone, cyclopentanone, cyclododecanone, mixtures from 2,2,4- and 2,4,4-trimethylcyclopentanone, cycloheptanone and cyclooctanone, cyclohexanone and all alkyl-substituted cyclohexanones having one or more alkyl radicals having a total of 1 to 8 hydrocarbon atoms, individually or in admixture. As examples of alkyl-substituted cyclohexanones there may be mentioned 4-tert-amylcyclohexanone, 2-sec-butylcyclohexanone, 2-tert-butylcyclohexanone, 4-tert-butylcyclohexanone, 2-methylcyclohexanone and 3,3,5-trimethylcyclohexanone.

Preferred are ketone-aldehyde resins based on the ketones acetophenone, cyclohexanone, 4-tert-butylcyclohexanone, 3,3,5-trimethylcyclohexanone and heptanone, alone or in admixture, and ketone resins based on cyclohexanone.

As aldehyde component of the ketone-aldehyde resins (component B)) are in principle unsubstituted or branched aldehydes, such as. As formaldehyde, acetaldehyde, n-butyraldehyde and / or iso-butyraldehyde, valeric aldehyde and dodecanal. In general, all the aldehydes mentioned in the literature as suitable for ketone resin syntheses can be used. Preferably, however, formaldehyde is used alone or in mixtures.

The required formaldehyde is usually used as about 20 to 40 wt .-% aqueous or alcoholic (eg, methanol or butanol) solution. Other uses of formaldehyde such. As well as the use of para-formaldehyde or trioxane are also possible. In principle, however, all formaldehyde donating compounds are suitable. Aromatic aldehydes, such as. B. benzaldehyde may also be included in admixture with formaldehyde.

Particularly preferred starting compounds for the ketone-aldehyde resins acetophenone, cyclohexanone, 4-tert-butylcyclohexanone, 3,3,5-trimethylcyclohexanone and heptanone used alone or in mixture and formaldehyde.

The molar ratio between the ketone and the aldehyde component is between 1: 0.25 to 1:15, preferably between 1: 0.9 to 1: 5 and more preferably between 1: 0.95 to 1: 4. Process for the preparation of the ketone-aldehyde resins are z. As described in EP 1 486 520, DE 102006009079.9 and DE 102006009080.2 and the literature cited therein.

Hydrogenated secondary products of the resins of ketone and aldehyde are also used as component B). The ketone-aldehyde resins described above are hydrogenated in the presence of a catalyst with hydrogen at pressures of up to 300 bar. The carbonyl group of the ketone-aldehyde resin is converted into a secondary hydroxy group. Depending on the reaction conditions, a part of the hydroxy groups can be split off, so that methylene groups result. To illustrate, the following scheme is used:

n = k + m

Process for the preparation of the hydrogenated products are z. As described in DE 102006009079.9 and DE 102006009080.2.

In the case of ketones containing aromatic structural elements, depending on the hydrogenation conditions, these structural elements are also hydrogenated. Suitable resins are for. B. in DE 102006026760.5 and DE 102006026758.3 described.

As component B), furthermore, urea-aldehyde resins are used with the use of a urea of the general formula (i)

in which X is oxygen or sulfur, A is an alkylene radical and n is 0 to 3, with 1,9 (n + 1) to 2,2 (n + 1) mol of an aldehyde of the general formula (ii)

in which R ₁ and R _{2 are} hydrocarbon radicals (for example alkyl, aryl and / or alkylaryl radicals) each having up to 20 carbon atoms and / or formaldehyde is used.

Suitable ureas of the general formula (i) with n = 0 are z. As urea and thiourea, with n = 1 methylene diurea, ethylene diurea, tetramethylene diurea and / or Hexamethylendiharnstoff and mixtures thereof. Preference is given to urea.

Suitable aldehydes of the general formula (ii) are, for example, isobutyraldehyde, 2-methylpentanal, 2-ethylhexanal and 2-phenylpropanal, and mixtures thereof. Isobutyraldehyde is preferred.

Formaldehyde may be in aqueous form, some or all of alcohols such. As methanol or ethanol may be used as paraformaldehyde and / or trioxane.

In general, all monomers described in the literature for the preparation of urea-aldehyde resins B) are suitable. Particularly preferred are urea, isobutyraldehyde and formaldehyde.

Typical methods of preparation and compositions are e.g. B. in DE 27 57 220, DE-OS 27 57 176 and EP 0 271 776 described. Commercial products are the Laropal ^® A81 or Laropal ^® A 101 from BASF AG.

Component B) is characterized by A hydroxyl number between 0 and 450 mg KOH / g, preferably between 0 and 375 mg KOH / g, more preferably between 0 and 350 mg KOH / g,

Gardner color number (50% by weight in ethyl acetate) between 0 and 5, preferably between 0 and 3.0, more preferably between 0 and 2.0, Gardner color number (50% by weight in ethyl acetate) after thermal loading of the resin (24 h, 150 ^° C.) between 0 and 10.0, preferably between 0 and 7.5, particularly preferably between 0 and 5.0,

• a number-average molecular weight Mn of 300 to 10,000 g / mol, preferably of 400 to 5,000 g / mol, more preferably of 400 to 3,000 g / mol, • a polydispersity (Mw / Mn) of between 1, 25 and 4.0, especially preferably between 1, 3 and 3.5,

• a melting point / range between 20 and 180 ⁰ C, preferably between 30 and 140 ⁰ C, more preferably between 40 and 130 ⁰ C and • a solubility in non-polar, organic solvents.

Again, the properties are arbitrarily variable.

The hydroxyl number is a measure of the polarity of the resins. The higher it is with otherwise constant parameters of the resin properties (eg carbonyl number, molecular weight), the higher the polarity. In order to ensure good compatibility with component A), the hydroxyl number should be chosen so low that the solubility is given in nonpolar solvents. On the other hand, subsequent layers adhere better to the primer layer, the more polar the primer is. The optimum hydroxyl number is between 0 and 450 mg KOH / g, preferably between 0 and 375 mg KOH / g, more preferably between 0 and 350 mg KOH / g. The determination is made in accordance with DIN 53240-2 "Determination of the Hydroxyl Number." It must be ensured that an acetylation time of 3 hours is exactly maintained.

The Gardner color number is determined in 50% strength by weight solution of component B) in ethyl acetate on the basis of DIN ISO 4630 and is a measure of the color of the resin. The smaller the color number, the more colorless is the resin. Also, the color number after thermal stress is determined in this way. This method can be used to give an indication of the heat resistance of component B). For this purpose, component B) is first 24 h at 150 ⁰ C in an air atmosphere stored (see determination of non-volatile content). The Gardner color number is then determined in 50% strength by weight solution of the thermally loaded resin in ethyl acetate on the basis of DIN ISO 4630. The lower the color number, the more heat-resistant the resin.

The measurement of the molecular weight and the polydispersity of component B) are carried out by gel permeation chromatography in tetrahydrofuran against polystyrene as standard. The polydispersity (Mw / Mn) is calculated from the ratio of weight average (Mw) to number average (Mn).

The higher the molecular weight, the higher the melting range of component B), and the better the drying rate, but the higher the solution viscosity. For a given molecular weight (Mn), the more dissimilar the dissolved polymer is, the higher the solution viscosity (high polydispersity).

Ideally, the number average molecular weight Mn is between 300 and 10,000 g / mol, preferably between 400 and 5,000 g / mol, more preferably between 400 and 3,000 g / mol and the polydispersity (Mw / Mn) between 1, 25 and 4, 0, more preferably between 1, 3 and 3.5.

The highest possible melting range of component B) is desirable so that z. B. the drying rate of the composition according to the invention, the hardness and the blocking resistance of the coatings are as high as possible.

The determination is carried out using a Kapillarschmelzpunkt-meter (Büchi B-545) based on DIN 53181. The preferred melting point / range of component B) is between 20 and 180 ⁰ C, preferably between 30 and 140 ⁰ C, more preferably between 40 and 130 ⁰ C.

The solubility of component B) is in common organic solvents such. Ethyl acetate, butyl acetate, acetone, butanone, etc. are added.

In addition, component B) is soluble in nonpolar solvents. This is absolutely necessary since it is only possible to homogeneously mix the very nonpolar component A) with the component B). The component B) is soluble in 10 and 50 wt .-% dilution in aromatic solvents such. As xylenes, toluene, benzene, cresols, naphthalene, tetrahydronaphthalene and / or in aliphatic solvents and solvent mixtures, such as decahydronaphthalene, hexane, heptane, (methyl) cyclohexane, crystal oils, white spirits, turpentine, paraffins alone or in admixture.

As xylene, toluene, benzene, cresols, naphthalene, tetrahydronaphthalene, decahydronaphthalene, hexane, heptane, (methyl) cyclohexane, crystal oils, white spirits, turpentine, paraffins alone or in admixture.

Preparation of the Compositions from Components A) to D):

The preparation of the compositions is carried out by intensive mixing of the components at temperatures of 20 to 80 ⁰ C ( "Textbook of lacquer technology", Th. Brock, M. Grote Klaes, P. Mischke, ed. V. Zorll, Vincentz Verlag, Hannover, 1998, Page 229 ff.), If appropriate in an inert gas atmosphere, to which component C) is initially charged and the components A), B) and optionally D) are added.

The inventive compositions of components A) to D) are free of chlorine. Chlorine-free means that no chlorine-containing products containing organically bound chlorine, such as. As chlorinated rubbers, chlorinated polyolefins or the like can be used. On the other hand, inorganic chlorides (eg salts) may be present, but they generally have no toxicological potential.

The invention also provides the use of the non-reactive compositions as primer compositions for improving the adhesion to plastics, in particular on unpretreated plastics.

The novel compositions of components A) to D) can be used as primer compositions that allow very good adhesion of adhesives, sealants and / or coating materials on untreated plastics, so that conventional methods for the pretreatment of plastics such. B. the flaming, the

Corona discharge, the plasma treatment or the gas phase fluorination omitted. It is sufficient according to the simple previous cleaning of the substrates with typical cleaning agents such. B. iso-propanol and / or n-hexane.

Particularly suitable are the compositions of the invention from the

Components A) to D) as a primer for improving the adhesion of adhesives, sealants and / or coating materials on unpretreated, low-energy plastics having a surface tension below 40, preferably below 38, more preferably below 34 have mN / m ² . However, it was surprising that the adhesion to glass was also improved.

As examples of such low-energy plastics are polyolefins such. B. polypropylene (PP), modified polypropylene, such as. As polypropylene-ethylene copolymers (eg., Block copolymers or random copolymers), polyethylene (PE), modified PE, mixtures such. As polypropylene / ethylene-propylene-diene blends (PP / EPDM) with low EPDM content, PP / PE blends, but also called rubbers, polyvinyl chloride or special polyester.

The plastics may be workpieces or moldings, composite materials such. As paper and / or aluminum laminations on plastic or films.

The plastics can be used in the commodity sector (eg bottles, cans, carrier bags, labels, etc.) or for high-quality applications (eg in the electronics industry, in the automotive or aircraft industry).

The novel compositions of components A) to D) have a rapid drying and a high blocking resistance.

The effect of the pretreatment also persists over a long period of time, so that optional pretreatment directly after the production of the plastic by the plastics manufacturer (off-line) or pretreatment directly before the application of the coating material (in-line) is possible.

Depending on the intended use, subsequent adhesives, sealants or coating materials are applied to the primer layers according to the invention. The subsequent layer can be applied directly to the primer "wet-on-wet", ie the solvent is not removed It is also possible first to free the primer from the volatile constituents at room temperature or elevated temperature and then the subsequent layer on the "dry" - ie solvent-free - to apply primer.

The composition of the invention can be applied to the plastic substrates by conventional methods. Examples include (electrostatic) spray, Spraying, spin coating, casting, dipping, tumbling, flooding, rolling, wiping, washing, printing, rolling, brushing, extruding.

The layer thickness of the primer layers according to the invention is after evaporation of the volatile components such. B. Solvents between 0.01 and 100 microns, preferably 0.1 and 30 microns, more preferably between 0.2 and 10 microns.

As subsequent coating materials it is possible to use all coating materials, in particular all solvent-containing, aqueous coating materials or solvent-free coating materials (eg radiation-curable coating materials and / or powder coatings) such as, for example, As fillers, fillers, base and / or topcoats and printing inks, ballpoint pen pastes, inks, polishes, glazes, laminations, heat sealing lacquers, cosmetics and / or sealing and insulating materials and adhesives.

The course of the compositions according to the invention on the substrates and the course of the subsequent coating materials on the compositions according to the invention is flawless and the surfaces are free from interferences, such as, for example, craters and wetting disorders.

The invention also relates to articles produced using the non-reactive compositions.

The following examples are intended to further illustrate the invention but not to limit its scope:

I.) Component A): Preparation of the polyolefin

Using a mixed contact of a crystalline titanium trichloride in the form of an aluminum-reduced TiCl ₄ (TiCl ₃ • 0.33 AICl ₃ ) and aluminum triisobutyl (in a weight ratio of 1: 4), the monomers given in Table 1 were dissolved in n-butane at the in Table 1 temperature polymerized in a laboratory autoclave, with hydrogen was used as molecular weight regulator. There were pressures of 15 to 35 bar. The monomers ethene and propene were added continuously during the reaction time of 3 h; the monomer 1 -butene was submitted. After 3 h, the reaction mixture was added with isopropanol, whereby the reaction was stopped. In an evaporator unreacted monomers and the solvent n-butane were evaporated. The melt of the polyolefin was discharged at a temperature of about 190 ⁰ C.

Preparation of primer compositions

The substances indicated in Table 3 below are dissolved with stirring and homogenized. For this purpose, the respective solvent (component C)) is introduced and the polyolefin 1-1 and the respective resin 11-1 to 11-3 slowly added with stirring at room temperature. To accelerate the dissolution, the mixture is heated briefly to 60 ^° C. with stirring. After dissolution, the solutions are filtered.

Table 3. Composition of Control V1 and Primers P1 through P6 (all data in grams / g)

V1 P1 P2 P3 P4 P5 P6 P7 P8

All solutions are clear to slightly cloudy, colorless to yellowish and water-thin. In comparative solution V1, the proportion of insoluble constituents was relatively higher than in compositions P1 to P8. This can be explained by the fact that the resins 11-1 to 11- 3 act as solubilizers.

The solutions V1 and P1 to P8 were applied by means of a doctor blade (2 μm wet layer) to films which had been previously cleaned with ethanol and n-hexane. After evaporation of the solvents (different flash off times, see Table 4), a printing ink was applied to the films by means of a doctor blade (2 μm wet layer) and freed from the solvents at room temperature.

The assessment of the adhesive properties was carried out according to the so-called crumple test. For this purpose, the coated film was "wrinkled" after 24 h after application of the printing ink If the coating is undamaged, the adhesion is very good (1)

Coating is the degree of injury assessed (2: minor flaking, ..., 6: complete detachment).

In addition, the adhesion was assessed by means of the tape tear-off method (Tesa test). For this purpose, an adhesive tape is glued to the ink film after different drying times of the printing ink (5 min, 1 h, 24 h) and then torn off again. If the coating is undamaged, the adhesion is very good (1). If the coating is damaged, the degree of injury is assessed (2: minor flaking, ..., 6: complete delamination).

A printing ink of the following composition was used:

39.0 g of ethanol 1 1, 2 g of ethyl acetate

40.0 g of synthetic resin 1201 (Degussa AG)

7.2 g Hacolor blue 50423 (hawthorn) The ingredients were added together in the order given with stirring and homogenized.

The following types were used as film substrates (Pütz films): Treofan NNA 40 (PP film), Hostaphan RN 50 (PET film), Genotherm EE 87 (PVC film)

Tables 4-1 and 4-2 below show the results of the adhesion tests (wrinkle test, Tesatest) of the printing inks on the respective primer P1 to P8 in comparison to the printing ink on the respective untreated film and on the comparative primer V1.

5 RT = room temperature

The adhesion of the ink to the respective plastic is poor without a primer layer. This is shown by the results of the wrinkle tests and the tesat tests. Only on PVC a slightly better adhesion (Tesatest 3 after 24 h) is found. Comparative experiment V1 shows that although a primer without component B) can fundamentally improve adhesion. However, a relative improvement is only observed after a flash off time of 2 minutes and is not at a very high level. In contrast, the adhesion of the printing ink on the plastic substrates is significantly improved already after short flash-off times by the primer layers according to the invention. It turns out that a higher concentration of component B) (P1 to P3) has a positive effect on the adhesion after short flash off times. Since all of these primer coatings are already tack-free after 30 seconds, high block resistance is guaranteed within a very short time.

Examples P4 to P6 show no significant differences compared to P1. The differences lie in the range of the measuring accuracy of the relative methods. Therefore, the influence of the solvent used (component C)) is low.

The solutions V1 and P1 to P8 were applied by means of a doctor blade (2 μm wet layer) to polyethylene and polypropylene panels from Krüppel, which had been previously cleaned with ethanol and n-hexane. After evaporation of the solvent, a printing ink was applied by means of a doctor blade (2 μm wet layer) and freed from the solvent at RT. In addition, a commercial 2-component polyurethane varnish was applied to the panels by spray application and dried over 30 min at 80 ⁰ C.

The adhesion properties of the printing inks were evaluated by means of a tape tear-off method (Tesa test). For this purpose, an adhesive tape was glued to the printing ink film after different drying times of the printing ink (5 min, 1 h, 24 h) and then torn off again. If the coating is undamaged, the adhesion is very good (1). If the coating is damaged, the degree of injury is assessed (2: minor flaking, ..., 6: complete delamination). For the applied paints, a cross-cut test was carried out in accordance with DIN EN ISO 2409 (GT 0 very good, GT 5 complete delamination).

The results are shown in Table 5.

Table 5. Results of the adhesion tests of the 2-component paints (cross-cut test) and the printing inks (Tesa test) on the respective primers P1 to P8 in comparison to Paint / ink on the respective untreated panel and on the comparison primer V1

The adhesion of the 2-component polyurethane coating to the respective plastic is poor without a primer layer. The same results result from the pretreatment by means of comparative primer V1. In all cases no liability is given (Crosscut GT 5). On PE, the adhesion is not improved by pretreatment using the inventive primer P1 to P8, when the primer was freed from the solvent at RT. If, however, the primers P1 to P8 according to the invention are freed from the solvent at elevated temperature, markedly improved adhesion results of the 2-component paint on PE result. On PP, the inventive primers P1 to P8 improve the adhesion of the paint excellent. However, the trend here is also that evaporation of the solvent at elevated temperature can further improve the adhesion properties.

The adhesion of the printing ink to the respective plastic without a primer layer is also poor (Tesa test 6). The pretreatment of PE by means of V1 shows after 5 min. evaporate the solvent at RT no improvement. A slight improvement, however, is found after forced drying of the primer. On PP slight improvements are found by pretreatment by means of V1. If the primers according to the invention are freed from the solvent at RT, the adhesion properties of the printing ink on the particular primer tend to be improved in the case of PE. By the forced drying at 100 ^° C. of the respective primer, on the other hand, very good adhesion properties of the printing ink to the thus pretreated PE panels are found. In the case of PP, the adhesion is excellent, regardless of the temperature during evaporation of the solvent.

Again, the examples P4 to P6 show no significant differences compared to P1. Therefore, the influence of the solvent used (component C)) is low.

Primer P1 was applied to Treofan NNA 40 (PP film) as described above. However, the ink was applied only 3 or 6 months after application of the primer. The investigation of the adhesion properties shows no differences in comparison to the investigations after direct application of the printing ink. It has therefore been proven that the adhesion-improving effect remains constant over a long period of time (see Table 6).
