摘　　要：研究端基改性非充油溶聚丁苯橡胶(SSBR)2466和充油SSBR2430在高性能轿车子午线轮胎胎面胶中的应用。结果表明:端基改性SSBR与白炭黑填料配合时,具有与乳聚丁苯橡胶明显不同的特点,其定伸应力较高、拉断伸长率较低,需通过配合剂进行调整,同时加工工艺上需适当提高加工强度,可获得满足高性能胎面胶性能要求的胶料。采用适当的应用配方进行轮胎试制,在生产过程中,胶料工艺通过性好,具有良好的挤出外观和尺寸稳定性,物理性能满足要求,动态粘弹性能优异。成品轮胎高速性能明显改善,滚动阻力明显降低。The application of oil-extended end-functionalized SSBR2466 and oil filled SSBR2430 in the tread compound of high performance passenger car radial tire was studied. The results showed that,the characteristics of end-functionalized SSBR filled with silica filler were different from that of ESBR：the modulus was higher, and the elongation at break was lower. Thus the ingredients in the for- mula and processing needed to be appropriately adjusted to provide high performance tread compound. It was found that when appropriate formula was applied for tire manufacture, the compound showed good processing properties, the appearance and dimensional stability of the extruded parts were good, the physical properties of the valcanizates met the requirements,and the dynamic viscoelastic proper- ties were excellent. The high speed performance of trial tire was improved significantly, and the rolling resistance decreased obviously.
