研究功能树脂Sylvatraxx 4401和Sylvatraxx 4202在半钢子午线轮胎胎面胶中的应用。结果表明,两种Sylvatraxx树脂的加入均能使硫化胶0~30℃温域内的损耗因子及胎面胶对干、湿路面的抓着力明显提高。加入Sylvatraxx对硫化胶的拉伸强度影响不大,但硫化胶的撕裂强度提高,特别是添加树脂4202硫化胶的阿克隆磨耗量和压缩生热降低。Sylvatraxx树脂的加入提高了白炭黑在橡胶中的分散性,降低了Payne效应,是一种有应用前途的高性能轮胎功能助剂。 相似文献

Rubber industry is facing a stiff challenge in the years to come. There are rising price for fossil fuel and shortage of resources. There is more stringent legislation to protect the environment and reduce the emission. Filler plays an important role in imparting useful properties to rubber products. In this article, the effects of new generation filler, on the physical properties, tearing energy, and abrasion resistance were investigated. The new generation filler, highly dispersible silica, has a dibutyl phthalate (DBP) absorption value of more than 180cc 100 g−1, more branched structure and relatively higher amount of small aggregates. Four different loadings of silica (up to 45 phr) were investigated. With increasing filler loading, the tensile strength and modulus at 300% elongation increased and the elongation-at-break decreased. The rebound resilience decreased and tan delta value improved with increasing silica content. The abradability continuously decreased with concomitant increase in the side coefficient force. The fatigue resistance was found to be better at higher silica loading. The silica particles due to its surface structure helps in crack arresting. The abradibility was related to tearing energy, loss modulus, and breaking energy. © 2019 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019 , 136, 47560. 相似文献
