FIELD: chemistry.
SUBSTANCE: invention relates to rubber industry and can be used in making wear-resistant rubber articles for construction purposes, operating in conditions of intense wear, low temperatures and aggressive media. The oil-and-petrol resistant rubber mixture contains butadiene-nitrile rubber BNKS-40AMN, isoprene rubber SKI-3, methyl styrene rubber SKMS-30 ARKM-15, sulphur, sulphenamide Ts, stearine, technical carbon P324, zinc oxide, regenerate RShT, thiuram D, kaolin, petroleum bitumen, naphtham-2, oil I-8A, N-nitrosodiphenylamine, and process additives - dispractol KS and a mixture of diphenyl carbonate and dimethyl carbonate resin DFK-1.
EFFECT: invention reduces the cost of the rubber mixture owing to use of cheaper process additives, and increases nominal tensile strength and breaking elongation, and reduces the abrasion index.
