FIELD: rubber compositions, chemical technology. ^ SUBSTANCE: invention relates to rubber mixture compositions and methods for their preparing. Preparing a rubber mixture composition involves mixing from 5 to 90 wt.-% of rubber component chosen from butyl rubber, halogenated butyl rubber, stellate butyl rubber, halogenated stellate butyl rubber, isobutylene homopolymer, chloroprene, butadiene-nitrile rubbers, ethylene-propylene-diene triple copolymers, ethylene-propylene copolymers, butadiene styrene rubbers, polybutadiene, polyisoprene, isoolefin-alkylstyrene copolymer, halogenated isoolefin-alkylstyrene copolymer, natural rubber, polypropylene, polyethylene, polyurethane, polyvinyl chloride, silicon rubber, propylene oxide polymer and their mixtures, from 0.01 to 5 wt.-% of amine compound represented by the formula: (R1R2R3)N wherein R1 means either hydrogen atom or hydrocarbyl group comprising from C4 to C30 carbon atoms; R2 means either hydrogen atom or hydrocarbyl group comprising from C1 to C30 carbon atoms, and R3 means either hydrogen atom or hydrocarbyl group comprising from C1 to C30 carbon atoms under condition that at least one radical among R1, R2 and R3 doesn't mean hydrogen atom, from 5 to 90 wt.-% of isoolefin copolymer comprising a link derivatized from halogenmethylstyrene, isoolefin link comprising from 4 to 7 carbon atoms, and copolymer comprises from 0.5 to 20 wt.-% of halogenmethylstyrene links and usual additives. Invention provides preparing the rubber mixture composition possessing the enhanced strength before treatment and enhanced stability against heat aging after vulcanization. ^ EFFECT: improved preparing method, improved and valuable properties of composition. ^ 51 cl, 4 tbl, 3 ex |
