MODIFIED RUBBER MOTHER BATCH, AND RUBBER MIXTURE AND VULCANIZED RUBBER MADE THEREFROM, AND METHODS OF THEIR PRODUCTION Russian patent published in 2017 - IPC C08L9/06 C08L21/02 C08J3/22 C08J3/24 

FIELD: rubber industry.

SUBSTANCE: invention relates to modified rubber master batch and its preparation method, rubber mixture, made from it, and vulcanized rubber and method of their production. Modified rubber mixture consists of non-cross-linked rubber and synthetic particles and/or natural rubber, having radiation cross-linked structure, dispersed in it, with average cross-linked rubber particles size from 20 to 500 nm and gel content of 60 wt% or more. Non-cross-linked rubber is styrene-butadiene rubber. Weight ratio of rubber particles, having radiation cross-linked structure, to non-cross-linked rubber ranges from more than 20:80 to less than or equal to 80:20. Rubber mixture contains mixture of modified rubber component and base rubber, in which modified rubber mother batch is present in amount from 1 to 70 weight parts per 100 weight parts of base rubber.

EFFECT: invention allows to reduce rolling resistance, increase slippage resistance on wet road and increase vulcanized rubber mixture wear resistance.
