FIELD: transport.
SUBSTANCE: invention relates to rubber industry, namely to the mix intended for forming tire bead squeezing part. Proposed mix comprises rubber component including at least one rubber from the group comprising natural rubber and epoxy natural rubber at least 30 parts by weight of silicon dioxide and at least no less 0.1 part by weight and not over 10 parts by weight of quinone di-imine compound per 100 parts by weight of said rubber component, and vulcanising agent. As quinone di-imine compound used is the compound representing N-{4-[(1,3-dimethyl bytil)imino]-2,5-cyclohexadiene-1-ilidine}-benzene amine. Proposed mix can additionally comprise not over 25 parts by weight of carbon black per 100 parts by weight of rubber component and not over 4 parts by weight of silane modifier per 100 parts by weight of silicon dioxide. Rubber component can comprise mix of natural rubber with epoxy natural rubber. Note here that content of said epoxy natural rubber can make at least 50% by weight of rubber component.
EFFECT: production of high-wear-resistance high-strength rubber plus lower consumption of oil origin products.
