摘　　要：以顺丁再生胶和聚丙烯为原料,分别采用机械共混法和动态硫化法制备顺丁再生胶/聚丙烯机械共混物和顺丁再生胶/聚丙烯热塑性弹性体。分析两种材料的硫化过程,比较其力学性能和热性能,并对材料的结晶/相转变化和材料断面形貌进行研究。结果表明,采用动态硫化法制备的热塑性弹性体能形成均相,表现出优异的力学性能和耐热性能。Using reclaimed butadiene rubber and polypropylene as raw materials,the RBR/PP blend and RBR/PP thermoplastic elastomer were prepared by mechanical blending and dynamic vulcanization respectively.The curing processing,mechanical properties and thermal properties of two samples were observed.In addition,the DSC curing and section morphology were also investigated.The results showed that the compatibility of RBR/PP thermoplastic elastomer was better than RBR/PP blend,and the comprehensive properties were greatly too.
