摘　　要： 研究了聚丙烯/三元乙丙橡胶(PP/EPDM)体系在过氧化二异丙苯(DCP)、硫磺(S)和酚醛树脂(PF)三种不同硫化条件下的动态硫化过程。探讨了膨胀型阻燃剂三聚氰胺磷酸盐(MP)和双季戊四醇(DPER)对PP/EPDM动态硫化体系力学性能和阻燃性能的影响。结果表明:在加入阻燃剂的情况下,PP/EPDM体系的阻燃性能得到了改善,但体系的力学性能下降较多。 The dynamically vulcanized processes of polypropylene/ethylene propylene diene monomer（PP/EPDM） thermoplastic elastomer vulcanized with three kinds of curing systems：dicumylperoxido（DCP）,sulfur,and phenolic resin were studied. The effects of intumescent flame retardants melamine phosphate （MP） and dipentaerythritol （DPER） on the mechanical properties and flame retardancy of dynamically vulcanized PP/EPDM thermoplastic elastomer materials were discussed. The results showed that the flame retardancy of the dynamically-vulcanized flame retardant systems was obviously improved with the addition of intumescent flame retardants,but the mechanical properties were decreased.
