摘　　要：制备了过氧化二异丙苯(DCP)和甲基丙烯酸甲酯(MMA)交联的氮磷阻燃剂阻燃聚丙烯(PP),研究交联剂与氮磷膨胀阻燃剂对阻燃PP的力学性能的影响。结果表明,交联剂能有效降低膨胀阻燃剂的用量,阻燃PP达到FV-0级时,未交联PP的膨胀阻燃剂最小质量分数为30%,而交联PP的膨胀阻燃剂最小质量分数为25%。The flame-retardant PP with phosphorus-nitrogen intumescent flame retardants cosslinked by DCP and MMA was prepared, and the effect of crosslinking agents and nitrogen-phosphous intumescent flame retardants on the flame retardancy of flame-retard- ant PP was studied. The results show that the crosslinking agents can reduce the amount of the intumescent flame retardants. When flame-retardant PP reaches FV -0 level, the minimum amount of intumescent flame retardants of uncrosslinked PP is 30%,but the minimum amount of intumescent flame retardants of crosslinked PP is 25%.
