低滚动阻力轮胎胎面胶的研究

Study on tread compound of low rolling resistance tire

采用正交试验方法 ,对胶料各组分进行优化 ,使胎面胶滚动阻力降低 ,同时又能保持良好的抗湿滑性能。试验结果表明 ,用溶聚丁苯橡胶替代乳聚丁苯橡胶和用白炭黑部分替代炭黑可以有效降低胎面胶的滚动阻力 ;填料总用量和芳烃油用量是影响滚动阻力和抗湿滑性能的最主要因素。

The various ingredients in tread compound were optimized with the orthogonal experi mental method to lower the rolling resistance of tire tread without sacrificing its wet traction.The test results showed that the rolling resistance of tire tread could be significantly decreased by using S SBR instead of E SBR,and silica partly instead of carbon black;and the total level of fillers and the level of aromatic oil were the main factors affecting the rolling resistance and wet traction of tire.methodtolowe
