RUBBER MIXTURE Russian patent published in 2024 - IPC C08L9/06 C08L9/02 

FIELD: chemistry.

SUBSTANCE: invention relates to the rubber industry, in particular to the production of rubber mixtures used for the manufacture of articles for various purposes, including for laying of rail connections of railway track. Rubber mixture contains isoprene rubber SKI-3, butadiene-methylstyrene rubber containing α-methylstyrene 22–25 wt.%, butadiene-nitrile rubber with acrylic acid nitrile content of 27–29 wt.%, sulphur, N,N'-dithiodimorpholine, tetramethylthiuram disulphide, N-cyclohexyl-2-benzothiazolylsulphenamide, zinc oxide, stearic acid, N-isopropyl-N'-phenyl-p-phenylenediamine, acetonanyl H, wax ZV-P, technical carbon N 220, technical carbon P 514, silicon dioxide Zeosil 1165 MP, hepsol HKP, rosin, N-nitrosodiphenylamine, industrial oil I-12A, trans-polynorbornene and diatomite NDP-D-400.

EFFECT: proposed invention allows to reduce weight change after daily exposure of industrial oil I-20A, to reduce change of conditional tensile strength, relative elongation at break and hardness, and also to increase tangent of angle of mechanical losses of rubber.
