Rubber mixture resistant to aggressive liquid environments

Abstract

The invention relates to the field of polymer chemistry, in particular to the production of a rubber mixture resistant to aggressive liquid environments. The claimed rubber mixture resistant to aggressive liquid environments is based on butadiene-nitrile and ethylene-propylene rubbers and contains stearic acid as a softener, zinc oxide as an activator, captax and thiuram as an accelerator, sulfur as a vulcanizer and technical carbon P324 as a filler, and according to the invention, additionally contains adipic acid and ED20 epoxy resin in the following ratio of components per 100 parts by mass of BNK / EPDM, kh: Butadiene-nitrile rubber (SKN-40) 60 Ethylene-propylene rubber (EPDM) 40 Sterain (softener) 2.0 Adipic acid 1.0-3.0 ED-20 2.6 Zinc oxide (activator) 5.0 Captax (accelerator) 1.2 Sulfur (vulcanizing agent) 1.8 Filler P324 (technical carbon) 45 Thiuram (TMTD) 0.8
