溶聚丁苯橡胶2466在轮胎胎面胶中的应用

Application of Solution Polymerized Styrene Butadiene Rubber 2466 in Tread Compound of Tire

研究溶聚丁苯橡胶(SSBR)2466在轮胎胎面胶中的应用。结果表明:在胎面胶中以SSBR2466替代SSBR2564S,并增大环保油用量,胶料的门尼粘度增大,焦烧时间延长,填料分散性提高;硫化胶的物理性能、耐磨性能和动态力学性能提高;成品轮胎的滚动阻力降低,抗湿滑性能提高。

The application of solution polymerized styrene butadiene rubber(SSBR) 2466 in the tread compound of tire was studied. The results showed that,by using SSBR2466 instead of SSBR2564 S in the tread compound,and increasing the addition level of environment-friendly oil,the Mooney viscosity of the compound increased,the scorching time was extended,and the dispersion of the filler was improved. The physical properties,wear resistance and dynamic mechanical properties of the vulcanizate were improved.The rolling resistance of the finished tire decreased and the wet skid resistance was improved.
