交联型白炭黑超级偶联剂SCBD在轮胎胎面胶中的应用研究

Application of Crosslinked Sillica Coupling Agent SCBD in Tire Tread

研究交联型白炭黑超级偶联剂SCBD在轮胎胎面胶中的应用。结果表明:在含白炭黑的斜交轮胎胎面胶中,偶联剂SCBD单用能降低胶料生热和滚动阻力,偶联剂SCBD与Si69并用降低胶料生热和滚动阻力的作用加强,且提高胶料的抗湿滑性能。在轿车子午线轮胎胎面胶中使用白炭黑/偶联剂SCBD/偶联剂1589体系,可实现胶料生热、滚动阻力和抗湿滑性能的良好平衡。

The application of crosslinked silica coupling agent SCBD in tire tread compounds was investigated. The results showed that when coupling agent SCBD was used in bias tire tread containing silica,the investigated. The results showed that when coupling agent SCBD was used in bias tire tread containing silica,the heat build-up and rolling resistance of compound were decreased. When coupling agent SCBD combined with Si69,heat build-up and rolling resistance of compound was decreased further,wet skid resistand was improved. Using silica/coupling agent SCBD/coupling agent 1589 system in PCR tire tread,the heat build-up,rolling resistance and wet skid resistance of compounds reached good balance.
