摘　　要：对高反式 1,4 聚异戊二烯 (TPI) /高乙烯基聚丁二烯橡胶 (HVBR) /SBR共混物的综合物理性能和动态力学性能进行研究。结果表明 ,共混物中TPI/HVBR/SBR并用比为 10 /2 0 /70时 ,共混物具有较低的滚动阻力和动态生热及优异的耐屈挠疲劳性和耐磨性 ,与TPI/SBR (并用比为 3 0 /70 )比较 ,其抗湿滑性提高 (0℃时的tanδ值增大76 3 % )。在SBR用量为 70～ 5 0份、TPI用量为 15～ 2 5份和HVBR用量为 15～ 3 5份范围内 ,共混物具有良好的综合性能 ,滚动阻力和抗湿滑性获得平衡 ,同时具有优异的耐磨性和耐屈挠疲劳性 。The physical properties and dynamic mechanical properties of TPI/HVBR/SBR blends were investigated.The results showed that the TPI/HVBR/SBR blend with blending ratio of 10/20/70 possessed lower rolling resistance and dynamic heat build up,excellent flex fatigue property and wear resistance,and its wet traction was higher than that of TPI/SBR blend with blending ratio of 30/70 (tan δ at 0 ℃ increased by 76.3%).The better comprehensive physical properties,balanced rolling resistance and wet traction,excellent flex fatigue property and wear resistance were obtained when 70～50 phr of SBR,15～25 phr of TPI and 15～35 phr of HVBR were used.
