FIELD: process engineering.
SUBSTANCE: invention relates to machine building and can be used for producing abrasive-polymer composition for porous abrasive tools. Composition components are taken in the following ratio, wt %: Silicon carbide or alundum - 55.6- 67.8; finely-dispersed chalk - 13.8-16.9; hydroxyl-containing oligomer polyoxypropylene polyether 10.2-20.4; diethylene glycol - 0.15-0.30; pentaerythritol - 0.23-0.45; 3,3-dichlor-4,4-diaminodiphenyl methane (diamet "x") - 1.05-2.10; toluene diisocyanate (T-65) - 3.37-6.75; crystallohydrate of calcium sulphate - 0.10-0.20; block polymer of poly-organosilicon hydride and poly-oxyalkylene ("КЭП"-2) - 0.20-0.40.
EFFECT: higher strength and elasticity of grinding tool, higher operating rotational speed.
