COMPOSITION OF COMPOSITE RUBBER-POLYMER MIXTURE OF TRIBOTECHNICAL PURPOSE Russian patent published in 2019 - IPC C08L9/02 C08L61/18 C08K3/04 

FIELD: technological processes.

SUBSTANCE: invention relates to the rubber industry and can be used in the manufacture of highly stressed friction for various purposes. Material based on rubber-polymer mixture contains a rubber mixture based on nitrile-butadiene rubber – raw rubber brand 3825. Coke-graphite flour is used as an antifriction filler. Mass ratio of coke-graphite flour and raw rubber is 1–2:3–4. Coke-graphite flour is pre-impregnated with novolak phenol-formaldehyde resin in a mass ratio of resin and flour equal to 1:2.

EFFECT: invention allows to improve the antifriction properties, to increase the deformation and strength characteristics and to increase the wear resistance of the material under abrasive conditions.
