FIELD: chemistry.
SUBSTANCE: invention relates to rubber-technical, tyre, footwear industry and other fields of technology, in particular, to rubber mixtures based on diene and ethylenepropylene elastomers, filled with silica white or its combination with technical carbon. Rubber mixture includes diene or ethylenepropylene caoutchouc, silica white with caoutchouc interaction promoter. As promoter mixture contains two-component composition. First component of composition - alkoxysilane, contains unsaturated hydrocarbon substituent at silicon atom, selected from group-gamma- methacryloxypropyl-trimethoxysilane and vinyl trimethoxysilane in quantity 1-6 wt.fr. per 100 wt.fr. of caoutchouc. Second component of composition is polyorganosiloxane with content of hydridesilane groups -1.0-1.7% and is selected from group methylhydridesiloxane and methyl(methyloctyl)hydridesiloxane in quantity 1.0-2.2 wt.fr per 100 wt.fr. of caoutchouc.
EFFECT: invention makes it possible to improve properties of rubber mixture and its vulcanisers, as well as to increase temperature of mixture preparation above 150°C without risk of scorching.
