摘要
研究低苯乙烯含量溶聚丁苯橡胶(SSBR)在载重子午线轮胎胎冠胶中的应用。结果表明:在载重子午线轮胎胎冠胶中采用低苯乙烯含量SSRR/天然橡胶(NR)/顺丁橡胶(BR)(并用比20/60/20)并用胶、白炭黑/炭黑并用补强体系,辅以低温混炼技术,胶料的抗撕裂性能、耐屈挠性能和耐老化性能好,老化后动态弹性模量增长率较小,成品轮胎的滚动阻力小,耐磨性能好。
The application of solution polymerized styrene butadiene rubber(SSBR) with low styrene content in the tread compound of TBR tire was investigated. In the compound, SSBR, NR and BR were blended at the ratio of 20/60/20. Reinforcing fillers were blend of silica and carbon black. The compound was processed by cold mixing process. The experimental test results showed that the tear resistance, flex resistance and aging resistance of the compound were good, and the increase of dynamic elastic modulus after aging was small. The finished tire showed low rolling resistance and good wear resistance.
