Abstract
The invention relates to a method for preparing rosin modified glass fiber reinforced plastic resin. Due to material proportion and catalyst optimization, the reaction speed is improved, the reaction gets stable, mild and is easy to control under lower temperature, therefore, excellent products of light color and high impact strength are obtained; the material formula is as follows: the molar ratio of rosin, crylic acid, ethylene glycol, glycol and fumaric is 1:1.3:1.5:2.3:2.3; the use amount of catalyst of vanadium pentoxide is 1-2% of the total material weight; the use amount of styrene is 30-45% of the total material weight; and the product is obtained through the processes of addition, esterification, polycondensation and mixing.
Description
Technical field
The invention belongs to a kind of rosin deep processing method.
Background technology
Rosin is the renewable resources of China's abundant, and annual production reaches more than 60 ten thousand tons, ranks first in the world.It has unique chemical structure and mulitiple chiral centers by a series of resin acid compositions, and the carboxyl in the structure and phenanthrene ring frame can carry out a series of chemical modification, are a kind of natural chiral source materials.Rosin can obtain a series of deep processed products through chemical modification, is widely used in the every field in the daily life, plays very important effect in the national economic development.The value ratio raw material rosin of these deep processed products is mentioned 2-10 doubly, even decades of times, and China mainly earns foreign exchange with outlet gum resin at present.China is the country of gum resin export volume maximum, accounts for about 60% of volume of world trade, and many developed countries export go back to again China from China's imported raw material rosin back through product after a series of deep processings, and are very unfavorable to conservation of resources and the Economic development of China.China is 35% to rosin deep processing and utilization rate, and by contrast, the developed country such as American-European near 100%, exists very large gap to the deep processing and utilization rate of rosin.Therefore, carry out Abietyl modified research, develop meet the China market demand deep processing rosin product not only to country and the development of local economy, and to the reasonable development of China's forest resourceies and utilization and at present industrial energy saving lower consumption and all be of great significance.Resinous acid as the rosin main component is a kind of two chemical reactivity centers that have---the chemically reactive substance of carboxylic acid and two keys, just can introduce atom or group at quarter by these two chain carriers, thereby give rosin and have desirable character, reach the purpose of modification, thereby change the rational performance of rosin, greatly expand the Application Areas of rosin, formed miscellaneous rosin derived product, be widely used in pressure sensitive adhesive, tackiness agent industry.Make multiple film glue, decorating glue, label glue, adhesive tape glue, hot melt adhesive, sanitary towel glue, non-setting adhesive, EVA hot melt adhesive, polyamide hot, seal gum, varnish paint vehicle, bookbinding glue, pipeline glue etc.In recent decades, rosin deep processing aspect, its product category, preparation method are all without large progress; There are the deficiencies such as sluggish length consuming time in prior art products preparation method.
Through Chinese publication retrieval, find 16 of relevant patents of invention, 4 of utility model patents the scheme identical with present patent application of not finding.
Summary of the invention
The object of the invention is to: for the deficiencies in the prior art, propose a kind of Abietyl modified fiber glass resin preparation method.
Abietyl modified fiber glass resin preparation method of the present invention comprises addition, esterification, polycondensation, mixed processes; It is characterized in that: its material formula is: rosin: dihydroxyphenyl propane: vinylformic acid: second glycol: ethylene glycol: fumaric mol ratio is 1:1:1.3:1.5:2.3:2.3; Catalyzer Vanadium Pentoxide in FLAKES consumption is 1-2% of total weight of material; The vinylbenzene consumption is 30-45% of total weight of material; Its processing step is as follows: with rosin heating and melting under rare gas element, heat up 180-200 ℃, control drips vinylformic acid with the speed that added in 45-50 minutes, then, be warming up to 250-260 ℃, reacted 80-90 minutes, be cooled to 90-100 ℃, add the second glycol, Vanadium Pentoxide in FLAKES, 200-220 ℃ of reactions of the temperature that heats up detected acid number after 90 minutes, after acid number drops to 30 milligrams of potassium hydroxide/gram, be cooled to 110-120 ℃, with ethylene glycol, dihydroxyphenyl propane, FUMARIC ACID TECH GRADE mixes rear adding, under 210-220 ℃, reacted 90-120 minutes, detect acid number, after acid number dropped to 40 milligrams of potassium hydroxide/gram, blowing mixed with it in the vinylbenzene and namely gets product.
The present invention's beneficial effect compared with prior art: by material proportion, catalyst optimization, make it speed of response and accelerate, and at a lower temperature reaction, make reaction become steadily, relax, be easy to control, thereby the acquisition lighter color, the good product that shock strength is high.
