An oil extended rubber comprising 100 parts by weight of (A) an amino group-containing copolymer rubber of a conjugated diolefin and an aromatic vinyl compound which contains bonded amino groups in the amount of 0.0025-0.20 mmol/g polymer, and 10-100 parts by weight of (B) an extensible oil. Carbon black, silica, a mixture of carbon black and silica, or a carbon-silica dual-phase-filler can be homogeneously dispersed in the oil extended rubber. Vulcanized products obtained by vulcanizing the rubber exhibits well-balanced improved properties such as wet skid properties, low hysteresis loss properties, abrasion resistance, and breaking strength, and are useful as a tread material for low fuel consumption tires, large tires, and high performance tires.
一种油延橡胶,由 100 重量份的(A)共轭二烯烃和芳香族乙烯基化合物的含氨基的共聚橡胶和 10-100 重量份的(B)延展性油组成,(A)共轭二烯烃和芳香族乙烯基化合物的含氨基的共聚橡胶含有键合氨基的量为 0.0025-0.20 mmol/g,(B)延展性油含有键合氨基的量为 0.0025-0.20 mmol/g。碳黑、白炭黑、碳黑和白炭黑混合物或碳硅双相填料可均匀地分散在延展性油橡胶中。通过硫化橡胶得到的硫化产品具有均衡的改良特性,如湿滑特性、低滞后损失特性、耐磨性和断裂强度,可用作低油耗轮胎、大型轮胎和高性能轮胎的胎面材料。
