Elastomer mixture

Abstract

The invention relates to the field of polymer chemistry, in particular to the production of high-performance elastomer compositions based on butadiene-nitrile rubber and ethylene propylene rubber. The claimed elastomer mixture is based on butadiene-nitrile and ethylene-propylene rubbers and contains EPDM-g-MA as a modifier, stearic acid as a plasticizer, zinc oxide as an activator, sulfur as an accelerator, vulcanizer and technical carbon P324 as a filler, and according to the invention, contains captax and thiuram as accelerators, and additionally liquid epoxychlorohydrin as a plasticizer in the following ratio of components per 100 parts by weight of BNK / EPDM, kh: Butadiene-nitrile rubber (SKN-40) 60 Ethylene-propylene rubber (EPDM) 40 EPDM-g-MA 5 Stearic acid 2 Liquid epoxy chlorohydrin 1-3 Zinc oxide 5.0 Captax 1.2 Sulfur 1.8 Filler P324 (technical carbon) 45 Thiuram (TMTD) 0.8
