摘　　要：研究了磷酸 -季戊四醇 -三聚氰酰胺聚合物的合成条件及膨胀效果 ,测定了阻燃聚丙烯的氧指数、水平燃烧性能 ,实验结果说明膨胀型阻燃剂的膨胀效果与组分有关 ,聚丙烯的阻燃效果随阻燃剂的膨胀效果增强 ,磷含量增大而显著改善。The synthetic conditions and intumescent effect of phosphoric acid pentaerythritol melamine polymer were studied. Fire retardance of PP was studied by means of testing oxygen index and horizontal flammability. The results showed: that the intumescent effect is affected by the composition of fire retardant. The fire retardance of PP is increased remarkably as the intumescent effect and phosphorus content increase.
