FIELD: chemistry.SUBSTANCE: invention relates to heat-resistant rubber mixtures and can be used in car, oil and industrial rubber industry. The heat-resistant rubber mixture contains butadiene-nitrile rubber, sulphur, thiazole 2 MBS, diphenyl guanidine, N-nitrosodiphenylamine, zinc oxide, stearin, dibutyl sebacate, technical carbon and diaphene SP. The mixture further contains an anti-ageing agent - powder form of Novantox 8 PFDA (Novantox 8 PFDA+schungite).EFFECT: improved resistance of rubber to thermal ageing on air, low cost of the mixture owing to reduced amount of the anti-ageing agent while maintaining sufficiently good physical and mechanical properties.2 tbl |
