Abstract A new strategy for high performance tire tread stocks is proposed by incorporating novel synthetic crystalline trans-1, 4-poly (butadiene-co-isoprene) rubber (TBIR) into the traditional amorphous SSBR/BR blends. The silica filled SSBR/BR/TBIR composites after chemical crosslinking exhibited significantly improved dynamical properties compared with filled SSBR/BR composites, such as 2–3 times higher tensile fatigue resistance, improved wet-skid resistance and abrasion resistance, lower rolling resistance and heat built-up, etc. Further discussions revealed that crystalline TBIR components improved silica dispersion by increasing the strength and modulus of SSBR/BR/TBIR rubber matrix, and modulated network structures of the rubber matrix in the form of TBIR lamellar fibrils, both of which were expected to contribute to the greatly improved tensile fatigue resistance and other properties. The incorporation of TBIR in tire tread stocks will provide a solution for high performance tire production without changing the present processing technology and formulations.

弹性体纳米复合材料通过 Trans -1, 4-poly(丁二烯-共-异戊二烯)掺入而具有优异的动态机械性能

摘要 通过将新型合成结晶 trans-1, 4-poly(丁二烯-共-异戊二烯)橡胶 (TBIR) 掺入到传统的无定形 SSBR/BR 共混物中,提出了一种高性能轮胎胎面胶料的新策略。化学交联后的二氧化硅填充的 SSBR/BR/TBIR 复合材料与填充 SSBR/BR 复合材料相比,表现出显着改善的动力学性能,例如拉伸疲劳强度提高 2-3 倍,提高抗湿滑性和耐磨性,降低滚动阻力和热进一步的讨论表明,结晶 TBIR 组分通过增加 SSBR/BR/TBIR 橡胶基质的强度和模量来改善二氧化硅的分散,并以 TBIR 层状原纤维的形式调节橡胶基质的网络结构,预计这两者都有助于大大提高抗拉伸疲劳性和其他性能。在轮胎胎面胶料中加入 TBIR 将为高性能轮胎生产提供解决方案,而不会改变目前的加工技术和配方。
