RUBBER MIXTURE Russian patent published in 2022 - IPC C08L9/06 C08K3/04 C08K3/06 C08K3/20 

FIELD: rubber industry.

SUBSTANCE: invention relates to the rubber industry and can be used in the production of rubber mixtures used for the manufacture of gaskets rail fasteners of the railway track. The rubber mixture contains butadiene-methylstyrene rubber with a content of α-methylstyrene 22-25 wt.%, isoprene rubber SKI-3, divinyl rubber with a content of cis-1,4 units of 87-95%, sulfur, N,N'-dithiodimorpholine, N -cyclohexyl-2-benzthiazolylsulfenamide, zinc oxide, stearic acid, N-isopropyl-N'-phenyl-n-phenylenediamine, acetonanil H, wax 3V-P, carbon black N 220, hollow corundum microspheres HCM-L kaolin, hepsol HKP, rosin, N-nitrosodiphenylamine, industrial oil I-12 A, trans-polynorbornene, basalt fiber and silicon dioxide Silica 1165 MP.

EFFECT: invention allows to increase relative tensile strength, hardness, tear resistance, reduce abrasion values, weight changes after daily exposure to industrial I-20A oil and water, provide high dielectric and dynamic properties of rubber.
