摘　　要：以多聚磷酸铵 (APP)和三聚氰胺 (MEL)为主阻燃剂 ,采用原位反应增容技术制备了非卤阻燃聚丙烯 ,从阻燃性能的角度对该有机膨胀型阻燃体系进行了优化探讨 ,并对原位反应的引发体系进行了初步筛选。结果表明 ,BPO和DCP体系都能引发原位反应 ,而且当阻燃母粒中m (APP) /m (MEL)为 5 /1、每 10 0g聚丙烯加入 15g季戊四醇时 ,可制得氧指数达 2 9%以上的非卤阻燃聚丙烯。sIn this paper halogen free flame retardant polypropylene(PP),in which ammonium polyphosphate(APP)and melamine(MEL) were used as main flame retardants, was prepared by means of in situ reactive compatibility technology As viewed from the flame retardance,the halogen free intumescent flame retardant system and in situ reactive conditions were investigated and optimized The experimental results showed that by adding masterbatch which were prepared at APP/MEL 5∶1(mass ratio),and pentaerythritol(PTH)15g per 100g PP,the halogen free flame retardant PP,the oxygen index( OI ) of which ≥29 0,could be prepared
