摘　　要：将溶聚丁苯橡胶(SSBR)PBR4003用于白炭黑和炭黑填充的高性能轮胎胎面胶配方中,研究其性能,并与SSBR 5025-2HM和2438-2HM进行对比。结果表明:PBR4003胶料的门尼焦烧时间与2438-2HM和5025-2HM胶料相近,但t90稍长;硫化胶的100%定伸应力和300%定伸应力高于2438-2HM和5025-2HM硫化胶,但拉断伸长率较低;硫化胶0℃下的tanδ值较大,具有较好的抗湿滑性能,60℃下的tanδ值较小,滚动阻力较低;PBR4003配合白炭黑使用性能更优异。The properties of high performance tire using silica and carbon black filled solution styrene-butadiene rubber（SSBR） PBR4003 were studied and compared with SSBR 5025-2 HM and 2438-2 HM. The results showed that the Mooney scorch time of PBR4003 compound was similar to 2438-2 HM and 5025-2 HM compound,but its t,0 was a little longer. The modulus at 100% and 300% elongation of PBR4003 vulcanizate were higher comparing with 2438-2 HM and 5025-2 HM vulcani- zates,but the elongation at break was lower. The tan8 at 0 ℃ of PBR4003 vulcanizate was higher which indicated the wet skid resistance was better,and the tan8 at 60 ℃ was lower which indicated the roiling resistance was lower. It was found that better properties of PBR4003 compound could be achieved hy using silica as filler.
