FIELD: rubber industry.

SUBSTANCE: invention relates to the rubber industry, in particular to the production of rubber compounds used for the manufacture of products for various purposes, including the production of rubber compounds for the manufacture of rail fastener pads of railway tracks. The rubber compound contains butadiene-methyl styrene rubber with a content of α-methyl styrene 22-25 wt. %, SKI-3 isoprene rubber, divinyl rubber with a content of cis-1,4, 87-95%, N-cyclohexyl-2-benzthiazolylsulfenamide, tetramethyl thiuram disulfide, N,N'-dithiodimorpholine, 2-mercaptobenztiazole, zinc oxide, stearic acid, N-isopropyl-N'-phenyl-n-phenylenediamine, acetonanyl H, wax ZV-P, carbon black N 220, silicon dioxide Zeosil 1165 MP, Hepsol HKP, kaolin, rosin, N-nitrosodiphenylamine, industrial oil I-12A, trans-polynorbornene and basalt fiber.

EFFECT: increase in relative elongation at break, a decrease in abrasion values, changes in mass after daily exposure to industrial I-20A oil, changes in conditional tensile strength, relative elongation at break and hardness after exposure to SZHR-1 oil, ensuring good dynamic and dielectric properties of rubber.
