中文摘要:
      应用动态硫化技术制备三元乙丙橡胶(EPDM)/聚1-丁烯(PB)热塑性硫化胶（TPV），研究不同橡塑比TPV及其返炼TPV的性能。结果表明：随着EPDM/PB共混比的减小，TPV的邵尔A型硬度、拉伸强度、撕裂强度逐渐增大；当EPDM/PB共混比为60/40时，TPV的拉断伸长率最大，热氧老化性能较好；在试验范围内，EPDM/PB共混比为70/30时，返炼TPV的性能最好。
英文摘要:
      EPDM/Poly（1-butene）（PB） thermoplastic vulcanizate（TPV）was prepared by dynamic vulcanization.The properties of the TPV and reprocessed TPV with different blending ratio of rubber and plastic were investigated.The results showed that，with the decrease of EPDM/PB blending ratio，the Shore A hardness，tensile strength and tear strength of the TPV increased．When EPDM/PB blending ratio was 60/40，the elongation at break and thermo-oxidative aging property of the TPV were the best．Within the scope of the experiment，when EPDM/PB blending ratio was 70/30，the properties of reprocessed TPV was the best.
