A kind of preparation method of carbon back high-abrasive material, concrete steps are following:
(1) said wearing layer and supporting layer are mixed by its set of dispense ratio respectively, and add the water of quality respectively, form wearing layer mixed liquor and supporting layer mixed liquor for 1 ~ 5 times in its mixture;
(2) wearing layer mixed liquor and supporting layer mixed liquor get up to the silk screen laminated through different pipelines while curtain coatings, and wherein wearing layer is on the upper strata, and supporting layer is in lower floor;
(3) silk screen is in vibrational state, makes the fiber in the wearing layer pass supporting layer, and through the roller extruding wearing layer firmly is connected with supporting layer;
(4) wearing layer is connected back formation carbon back high-abrasive material of the present invention with supporting layer, and wherein residual moisture is sloughed through extruding and oven dry.
Beneficial technical effects of the present invention is:
One deck carbon fiber is as thin as a wafer arranged on the surface of abrasives of the present invention, and closeness is 20 ~ 30g/m
2, be evenly distributed, have excellent abrasive and temperature tolerance.Not only rely on resin-bondedly between carbon fiber layer and the base material, and have fiber intert to connect, with the base material strong bonded.Thermal conductivity that carbon fiber is good and temperature tolerance can well be protected the material of basic unit.Because of the requirement of its friction characteristics is reduced, price is also comparatively cheap, and the price of the price of whole wearing piece and traditional paper substrate wearing piece is close, and can be used to be attached at the friction lining on the automobile synchronizer tooth ring.
The specific embodiment
Embodiment 1
The preparation method of this carbon back high-abrasive material is:
(1) with the component of wearing layer: carbon fiber 18%, acrylonitrile pulp 8%, velveteen pulp 19%, nanometer phenolic resins 22%, graphite 6%, iron oxide red 6%, aluminium oxide 3%, calcium carbonate 10%, carboxylic acrylonitrile butadiene rubber latex 5%, aluminum sulfate 1.98%, NaOH 1%, polyacrylamide 0.02% mix; Add the water of 3 times of mixture qualities, be made into the wearing layer mixed liquor;
Component with supporting layer: velveteen pulp 24%, glass fibre 30%, calcium carbonate 14%, aluminum sulfate 1.98%, polyacrylamide 0.02%, nanometer phenolic resins 18%, cotton thread weaving leftover pieces 12% mix; Add the water of 3 times of mixture qualities, be made into the wearing layer mixed liquor;
