ABRASIVE-POLYMERIC COMPOSITION Russian patent published in 1995 - IPC

FIELD: abrasive tool making. SUBSTANCE: composition has polydivinylisoprene epoxyureathane rubber PDI-ZA and epoxy novolacs block-copolymer, hardeners aniline or a mixture of aniline with quinol ether EX-1, gasifier, surface-active substance, abrasive taken at the following ratio, wt.-% abrasive 70-80; rubber PDI-ZA 15.8-28.0; epoxy novolacs block-copolymer 0.9-1.0, hardener 0.2-0.3; azoisobutyronitrile 0.4-0.7; block-copolymer of polyorganosiloxane and polyhydroxyalkylene 0.4-0.7. If aniline is used as a hardener the following ratio of components is used, wt.-% abrasive 70-80; rubber PDI-ZA 17.4-28.0; epoxynovolacs block-copolymer 0.9-1.0; aniline 0.2-0.3; azoisobutyronitrile 0.4-0.7, and block-copolymer of polyorganosiloxane and polyhydroxyalkylene 0.4-0.7. If a mixture of aniline and quinol ether is used as a hardener then the ratio of components will be: abrasive 70-80; rubber PDI-ZA 15.8-21.9; epoxy novolacs block-copolymer 0.9-1.0; aniline 0.2-0.3; quinol ether EX-1 1.6-2.5; azoisobutyronitruile 0.5-0.7, block-copolymer polyorganosiloxane and polyhydroxyalkylene 0.5-0.7. EFFECT: enhanced quality of composition. 3 cl, 1 tbl
