国产溶聚丁苯橡胶在绿色轮胎胎面胶中的应用

Application of Domestic SSBR in Green Tire Tread Compound

研究国产溶聚丁苯橡胶(SSBR)在绿色轮胎胎面胶中的应用,并与进口SSBR和乳聚丁苯橡胶(ESBR)进行对比。结果表明:与ESBR成品轮胎相比,SSBR成品轮胎高速性能、耐久性能和胎面强度相当,均满足标准要求,滚动阻力降低,湿抓着性能提高,其中国产SSBR2557S湿抓着性能增幅更大,且在应对标签法规方面意义重大。

The application of domestic SSBR in green tire tread compound was studied and compared with imported SSBR and ESBR. The results showed that, compared with the tire with ESBR tread, the high- speed performance, endurance performance and tread strength of the tire with SSBR tread were similar, and met the requirements of corresponding standards. It was found that the rolling resistance of the tire with SSBR tread was lower and the wet grip performance was better. Especially, the wet grip performance of the tire with domestic SSBR2557S in tread compound was even better,which was very important in complying with the labeling act.
