RUBBER MIXTURE Russian patent published in 1994 - IPC

FIELD: rubber industry. SUBSTANCE: new rubber mixture includes 100 parts of polymer compound, 1.0 to 5.0 parts of curing agent, 1.0 to 5.0 parts of metal oxide, and 1.0 to 2.0 parts of organic compound to activate curing. Polymer compound further includes 60 to 80 parts of butadiene/methyl/styrene rubber, 20 to 40 parts of polyvinylchloride, and modified additive - 2,6-ditertbutyl-4-methylamino- dimethylphenol or 1.0 to 1.5 parts of poly/N-3,5-ditertbutyl-4- oxytolyl/ethylenimine. Rubber mixture may additionally contain 10 to 80 parts of filler. Thus prepared vulcanized rubber possess excellent physical- mechanical characteristics, namely: modulus of elasticity in 100-percent tension, relative tensile strength, elongation, hardness, fire-proofness and resistance to influence of ozone. EFFECT: better characteristics of rubber mixture. 2 cl, 2 tbl
