FIELD OF THE INVENTION The invention relates to the field of rubber and tire industry. To improve the tackiness and technological properties of the rubber mixture while maintaining the level of physical and mechanical properties of the vulcanizates, the rubber mixture contains cis-polyisopene rubber with 24–36% of fractions with mol.m. above 10 and 3-7% of fractions from a pier, May. below 10, Rubber compounding (mac): indicated cis-polyisoprene rubber 60-90, butadiene rubber 10-40, sulfur 1-4; vulcanization accelerators 0.6-3; oxides of zinc 2-10 fillers 40-140, emulsifiers 5-40; antioxidants 0.5-2 and activators-dispersants 0.5-4. 3 tab. to |
