摘　　要：制备天然橡胶(NR)/乙烯-乙酸乙烯酯共聚物(EVA)/高密度聚乙烯(HDPE)热塑性硫化胶(TPV)并研究其性能。结果表明,当动态硫化时间为8 min、EVA用量为12份、炭黑N330用量为40份时,NR/EVA/HDPE TPV的综合物理性能最好。Natural rubber(NR)/ethylene-vinyl acetate copolymer(EVA)/high-density polyethylene(HDPE)thermoplastic vulcanizate(TPV)was prepared and its properties were studied.The results showed that when the dynamic curing time was 8 min,the amount of EVA was 12 phr,and the amount of carbon black N330 was 40 phr,the NR/EVA/HDPE TPV had the best comprehensive physical properties.
