FIELD: chemistry.

SUBSTANCE: rubber mixture based on butadiene-methylstyrene caoutchouc includes a vulcanising agent, a mixture of vulcanisation accelerators - dibenzothiazoledisulphide and diphenylguanidine, zinc oxide, an organic vulcanisation activator, a modifying additive - zirconium dioxide and filler with a component ratio, wt. p.: butadiene-methylstyrene caoutchouc - 100.0; sulphur- 2.0; zinc oxide - 5.0; stearic acid - 2.0; dibenzothiazoledisulphide - 1.5; diphenylguanidine - 0.3; technical carbon - 40.0; zirconium dioxide - 25.0-40.0.

EFFECT: invention makes it possible to increase the heat- and fire resistance of vulcanisates with the preservation of high physical-mechanical indices.
