摘　　要：以过氧化二异丙苯(DCP)为交联剂、偶氮二甲酰胺(AC)为发泡剂,采用化学交联法,使热塑性弹性体(TPE)、低密度聚乙烯(LDPE)、乙烯醋酸乙烯共聚物(EVA)树脂形成泡孔均匀的发泡产品。研究了不同配比的树脂在泡沫塑料中的性能。结果表明,在LDPE、EVA中添加TPE的泡沫塑料性能均有所提高。A foamed plastics product with fine cells was prepared from TPE, LDPE and EVA resins by means of chemical crosslinking, with DCP as crosslinking agent and AC as blowing agent. The function of the resin of different comparison in the foamed plastics was studied. The results showed when TPE was blended with LDPE and EVA in the foamed plastics, the properties of the foamed plastics were all improved.
