Aluminium oxide, after kneading uniformly, beats triangle bag 2～3 times at 75～85 DEG C；
Step s2, after adjustment roll spacing 3～4mm, adds semi-reinforcing hydrocarbon black, nano silicon and modified celestite powder, treats material
After mixing uniformly, the material cleaning in receiver adds in elastomeric compound, is eventually adding Cosan, continuously makes a call to 3～4 triangle bags；
Step s3, adjusts roll spacing 1～2mm, thin for sizing material roller blanking controls 70 DEG C of roller temperature ＜, cuts out bar standby；
Step s4, the adhesive tape cutting out is measured and puts in beater, then will be complete to magnesium stearate, mercaptoethanol, graphite and glycerol
Portion pulverizes and puts in beater, obtains mixed material, is eventually adding dimethylbenzene, pulls an oar 4～5 hours, treats not having particulate matter in rubber cement
Obtain final product described dipping rubber slurry.
4. high abrasion clutch surface according to claim 1 is it is characterised in that the preparation method of described impregnating resin
For: will pulverize after 30 parts of phenolic resin, 8 parts of Lauxites and 40 parts of hexamethylenetetramine mix homogeneously, add 150 parts of ethanol
Mix, put in blender and break into impregnating resin solution.
5. the preparation method of high abrasion clutch surface described in claim 1 is it is characterised in that comprise the steps:
Step s1, copper fiber and aramid fiber are pre-machined into compound linear fiber；
Step s2, compound linear fiber impregnates in impregnating resin so as to resinous amount controls 16～20%；
Step s3, impregnates in dipping rubber slurry, and weight proportion is compound linear fiber: dipping rubber slurry=1:0.9～
1.3；
Step s4, then through around embryo, hot pressing, heat treatment, mill processing, obtaining final product.
6. preparation method according to claim 5 it is characterised in that: step s2 be combined linear fiber soak in impregnating resin
Stain is so as to resinous amount controls 18%.
7. preparation method according to claim 5 it is characterised in that: compound linear fiber and dipping latices in step s3
The weight ratio of material is 1:1.1.
