| 中文摘要: |
| 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 5025-2 HM和2438-2 HM进行对比。结果表明：PBR4003胶料的门尼焦烧时间与2438-2 HM和5025-2 HM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2438-2 HM和5025-2 HM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。 |
| 英文摘要: |
| The properties of high performance tire using silica and carbon black filled solution styrenebutadiene 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 t90 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 vulcanizates,but the elongation at break was lower. The tanδ at 0 ℃ of PBR4003 vulcanizate was higher which indicated the wetskid resistance was better, and the tanδ at 60 ℃ was lower which indicated the rolling resistance was lower. It was found that better properties of PBR4003 compound could be achieved by using silica as filler. |
