| 摘 要： | 研究天然橡胶(NR)/顺丁橡胶(BR)/1,2-聚丁二烯橡胶(1,2-PBR)并用胶的硫化特性、物理性能及动态力学性能,确定适用于轮胎胎面胶的BR/1,2-PBR最佳并用比。结果表明:与NR或BR相比,1,2-PBR加工性能稍差。当BR/1,2-PBR并用比为25/5时,NR/BR/1,2-PBR并用胶的综合物理性能和抗湿滑性能较好;当BR/1,2-PBR并用比为15/15时,并用胶的压缩温升低,压缩永久变形最小,综合力学性能优异,更适合应用于轮胎胎面。

| Abstract: | The curing behavior,physical properties and dynamic mechanical property of NR/BR/1,2-polybutadiene rubber(1,2-PBR) blends were studied,and the optimum blending ratio of BR/1,2-PBR was obtained.The results showed that,compared with those of NR or BR,the processability of 1,2-PBR was poor.As the blending ratio of BR/1,2-PBR was 25/5,the NR/BR/1,2-PBR blend possessed better comprehensive physical properties and wet skid resistance.When the BR/1,2-PBR blending ratio was 15/15,the blend had lower compression temperature rise,lower compression set,and good mechanical property.The blend with BR/1,2-PBR blending ratio at 15/15 was more suitable for tire tread. |
