The invention relates to the technical field of tire preparation processes, and discloses a tire tread rubber composition, which is prepared from the following raw materials in parts by weight: 50 to 80 parts of polystyrene-butadiene rubber, 5 to 20 parts of cis-1, 4-polyisoprene rubber, 5 to 20 parts of polybutadiene rubber, 70 to 100 parts of white carbon black, 15 to 50 parts of wet-skid-resistant resin and 5 to 10 parts of silane coupling agent. The semi-steel all-season tire produced from the rubber composition has excellent dry and wet land braking performance and ice and snow land performance, meanwhile, the wet-skid and rolling resistance performance of the formula is not affected, the Tg point of the rubber material can meet the use requirements of different temperature environments in four seasons, the diversified performance requirements of the market for tires are met, and the semi-steel all-season tire is particularly suitable for Europe and northern China.
本发明涉及轮胎制备工艺技术领域,公开了一种轮胎胎面橡胶组合物,包括以下重量份数的原料:溶聚苯乙烯-丁二烯橡胶50-80份、顺1,4-聚异戊二烯橡胶5-20份、聚丁二烯橡胶5-20份、白炭黑70-100份、抗湿滑树脂15-50份、硅烷偶联剂5-10份。本发明的橡胶组合物生产的半钢全季轮胎具有优异的干湿地制动性能及冰雪地性能,同时不影响配方湿滑及滚阻性能,其胶料Tg点可达到四季不同温度环境使用需求,满足市场对轮胎的多元化性能需求,尤其适用于欧洲及中国北方地区。
