摘　　要：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.Enhancement additives,Sylvatraxx 4401 and Sylvatraxx 4202 were applied in the tread compound of steel-belted radial tire. The results showed that,the addition of function resin increased the loss factor of the vulcanizate at the temperature range from 0 to 30 ℃ apparently,which improved the traction of tread on both dry and wet road. Sylvatraxx had no apparent influence on the tensile strength,but could increase the tear strength of the vulcanizate,especially,Sylvatraxx 4202 could decrease the Akron abrasion and heat build-up. The addition of Sylvatraxx resins improved the dispersion of silica in rubber matrix,and weakened Payne effect,so they were promising functional additives for high performance tire.
