RUBBER MIXTURE, PREPARATION METHOD THEREOF AND CURED RUBBER PRODUCED THEREFROM Russian patent published in 2017 - IPC C08L9/06 C08J3/24 C08J3/26 C08J3/28 C08L21/02 C08L9/08 B60C1/00 C08L23/22 

FIELD: rubber industry.

SUBSTANCE: invention relates to rubber mixture, method of its production and cured rubber from it. Rubber mixture contains non-crosslinked rubber and rubber particles, having radiation cross-linked structure, dispersed in it. Particles of rubber, are particles of synthetic rubber and/or natural rubber particles with average particles size from 20 to 500 nm and content of gel of 60 wt%. or more. Non-crosslinked rubber is butadiene-styrene rubber. Weight ratio of rubber particles, having radiation cross-linked structure, and non- cross-linked rubber ranges from 1:99 to 20:80. Rubber mixture is produced by mixing of components, containing non- cross-linked rubber latex and rubber particles latex, having radiation cross-linked structure, and their subsequent coagulation. Rubber particles latex, having radiation cross-linked structure, is rubber latex after radiation cross-linking.

EFFECT: invention allows to improve rolling resistance, resistance to slipping on wet road and wear resistance of cured rubber from rubber mixture.
