不同结构白炭黑对绿色轮胎胎面胶性能的影响
|
摘要
研究不同结构白炭黑对绿色轮胎胎面胶[溶聚丁苯橡胶(SSBR)/顺丁橡胶(BR)并用胶]性能的影响。结果表明:白炭黑1165MP的平均粒径最小,补强性能最佳,填充胶的抗湿滑性能最优;白炭黑WL180在SSBR/BR并用胶中分散均匀,填充胶的滚动阻力最低;白炭黑VN3在SSBR/BR并用胶中的分散性最好;白炭黑T383的平均粒径最大,补强性能最差;白炭黑DNS2分散性较差,填充胶的Payne效应最明显。
The effects of silica with different structure on the properties of green tire tread compound [solution polystyrene-butadiene rubber(SSBR)/cis-butadiene rubber(BR) blend] were studied. The results showed that,the average particle size of silica 1165 MP was the smallest,the reinforcing property was the best,and the wet resistance of the filled compound was the best. Silica WL180 was uniformity dispersed in the SSBR/BR blend,and the rolling resistance of the filled compound was the lowest. The dispersion of silica VN3 in SSBR/BR blends was the best. The average particle size of silica T383 was the largest,and the reinforcing property was the worst. The dispersion of silica DNS2 was poor,and Payne effect of the filled compound was the most obvious.
