摘　　要：测定了不同组分的聚磷酸 -季戊四醇酯 -三聚氰酰胺共聚物阻燃剂的膨胀度 (ID) ,阻燃聚丙烯的氧指数 (OI)、水平燃烧性能 .实验结果说明膨胀型阻燃剂的ID与组分及结构有关 ,聚丙烯的阻燃效果与阻燃剂的ID及聚丙烯的烧滴特性有关 .The intumescent effect of a series of polymer of phosphoric acid -pentaerythritol - melamine, with different components was studied. Fire retardancy of PP was studied by means of testing oxygen index and horizontal flammability. The results showed that the intumescent effect is dependent on the components and structure of fire retardant; the fire retardancy of PP is affected by the intumescent effect and the dropping character of PP.
