FIELD: chemistry.SUBSTANCE: invention relates to rubber composition, in particular, for obtaining tyres or half-finished products for tyres. Rubber composition consists of at least diene elastomer, enhancing filler, cross-linking system, epoxy resin - from more than 1 to less than 20 phr and amine hardening agent - from more than 1 to less than 15 phr. Amine hardening agent is selected from the group, consisting of p-xilylenediamine, 1,3-bis(aminomethyl)cyclohexane, 1,8-diaminooctane, 3,3?-diaminobenzidine and their mixtures. Enhancing filler contains soot, silica or their mixture.EFFECT: invention makes it possible to provide high rigidity with low deformation without noticeable impairment of hysteresis.11 cl, 2 tbl |
