低滚动阻力轿车轮胎胎面胶配方的研究

研究低滚动阻力轿车轮胎胎面胶的配方。结果表明:在胎面胶中使用溶聚丁苯橡胶并填充一定量的高分散白炭黑,可加快胶料的硫化速度,提高硫化胶的定伸应力和拉伸强度,改善硫化胶的动态性能;成品轮胎的高速性能和耐久性能均达到国家标准要求,滚动阻力明显降低。

Study on Tread Compound Formulation of Low Rolling Resistance Passenger Car Tire

The tread compound formulation of low rolling resistance passenger car tire was investigated.The results showed that,by using solution polymerized styrene butadiene rubber and highly dispersed silica in the tread compound,the curing rate of compound increased,the modulus and tensile strength of the vulcanizates increased,and the dynamic properties were improved.The high speed performance and endurance performance of the finished tire met the requirements of national standards,and the rolling resistance was significantly reduced.
