摘　　要：分别以共混和共聚的方式,制备了三种不同的含磷阻燃共聚酯(FRPET)。并对三种FRPET的阻燃效果进行了比较。结果表明,共混型阻燃剂2-(2-羟苯基)苯膦酸盐(HAPP-Na)的加入对PET有一定的阻燃效果,磷含量为0.6%(质量分数)时,极限氧指数达到了26.4%;相同磷含量的共聚型阻燃剂DDP比共混型阻燃剂HAPP-Na的阻燃效果好,但是两者的熔滴现象都较严重;由于磷硅协同作用,使反应型磷硅阻燃剂DOPO-Si比只含有磷元素的DDP的阻燃效果好,而且具有抗熔滴的效果。Three kinds of phosphorus-containing flame-retardant copolyesters were prepared by the way of blend and copolymerization,and then the flame retardancy of the FRPET was compared.The results show that the flame retardancy of FRPET,which was blended with HAPP-Na,is improved.The LOI value of FRPET is enhanced up to 26.4% with 0.9 %(mass fraction)phosphorus.The flame-retardant properties of FRPET with DOPO-Si which simultaneously contain phosphorus and silicon is better than that with DDP containing only phosphorus due to the synergistic effect of the elements phosphorus and silicon on the flame retardant.
