摘　　要：采用动态硫化法制备IIR再生胶/聚丙烯热塑性硫化胶(RIIR/PP TPV),并对其性能进行研究。结果表明,当RIIR/PP共混比为60/40时,TPV的综合物理性能较好;RIIR/PP TPV的耐溶剂性能和热稳定性能较好,加工性能优异;扫描电子显微镜分析表明,RIIR/PP TPV中的橡胶粒子细小,分散均匀,两相相容性较好,界面强度提高。Reclaimed isobutylene-isoprene rubber/polypropylene thermoplastic vulcanizate （RIIR/ PP TPV） was prepared by dynamic vulcanization and the properties of TPV were investigated. The results showed that when the blending ratio of RIIR/PP was 60/40,good comprehensive physical properties of the TPV were obtained. The RIIR/PP TPV possessed good solvent resistance,thermal stability and processing property. It was found by SEM that rubber phase was in small size and uniformly distributed;the compatibility and interfacial force between RIIR and PP phase were improved.
