中文摘要: |
在传统的胎面胶配方NR/SBR1500(并用比为60/40)和SBR1712/SBR1500(并用比为60/40)的基础上,采用高反式-1,4-聚异戊二烯(TPI)和/或高乙烯基聚丁二烯橡胶(HVBR)取代或部分取代SBR1500,研究共混物的物理性能和动态粘弹性。结果表明,添加了TPI和HVBR的胎面胶,其力学性能可满足使用要求,定伸应力和抗屈挠疲劳性有较大提高,滚动阻力和动态生热明显降低,而抗湿滑性仍有较高的保持率,达到了滚动阻力和抗湿滑性能的良好兼备。相对而言,NR/TPI/HVBR并用胎面胶具有更小的滚动阻力和生热,而SBR/TPI/HVBR并用胎面胶具有更好的抗湿滑性、抗屈挠疲劳性和耐磨性。 |

TPI and/or HVBR were used to replace or partly replace SBR1500 in the traditional NR/SBR1500(60/40)and SBR1712/SBR1500(60/40) tread compounds.The physical properties and dynamic viscoelasticity of various blend compounds were investigated.The results showed that the test tread compounds with TPI and/or HVBR possessed satisfactory mechanical properties,increased modulus and flex fatigue property,significantly reduced rolling resistance and dynamic heat build-up,and better wet traction,and by comparison,NR/TPI/HVBR tread compound had lower rolling resistance and heat build-up,and SBR/TPI/HVBR tread compound had better wet traction,flex fatigue property and wear resistance. |
