VULCANIZABLE RUBBER MIXTURE Russian patent published in 2019 - IPC C08L9/02 C08K3/04 C08K5/18 C08K5/32 

FIELD: technological processes.

SUBSTANCE: invention relates to rubber industry and can be used in machine building, oil producing and oil refining industry. Rubber mixture contains the following components, pts. wt.: hydrogenated butadiene-nitrile rubber 100, vulcanizing agent N,N'-bis-n-nitrosophenylderivative of alkanediamine 3–7, technical carbon 40–50, plasticizer 6–10, stearic acid 1–2, antioxidant 0–1.

EFFECT: higher speed of vulcanization of rubber mixtures based on hydrogenated butadiene-nitrile rubber, obtaining rubber with low level of accumulation of relative static deformation of static compression under conditions of high temperatures, resistance to aging processes, heat resistance and resistance to action of liquid aggressive media.
