The invention relates to rubber compounds based on unsaturated rubber and can be used in the tire industry in the production of massive and super large tires. The purpose of the invention is to increase the strength, elongation and bond strength of rubber with textile cord after heat aging. For this purpose, a scorch retarder and 2-mercaptobenzimidazole (MBI) are introduced with the ratio of the latter with alkylphenol disulfide-formaldehyde resin (AFDSFS) 1: 4-8. The rubber mixture contains unsaturated rubber, carbon black, plasticizer, zinc white, stearic acid, M-isopropyl-N- -phenylphenylenedinamine, hexachloro-para-silol, vulcanization accelerator, vulcanizing agent, AFDSPS, retarder, and vulcanizing, MBI, curing, MBI, and vulcanizing agent, MBI, and vulcanizing agent, MBI, and vulcanizing agent, MBI, and vulcanizing agent, MBI, and vulcanizing agent, MBI, and vulcanizing agent, MBI, and vulcanizing agent; including: 100; 30-60; 4-16; 3-8; 1-3; 1-3; 0.3-1; 0.6-4; 0.6-2.5; 3-8; 0.1-0.7; 0.5-2. 5 tab. cl G |
