将溴化聚苯乙烯(BPS)和三氧化二锑(AO)作为协效阻燃剂,利用熔融共混法制备了聚对苯二甲酸乙二醇酯(PET)阻燃复合材料,考察了其阻燃性能和力学性能。结果表明:复合阻燃剂BPS/Sb203添加量为10%就能达到垂直燃烧的V-0等级,氧指数达到25.4%,但会引起力学性能的大幅下降。为了改善力学性能,选取复合阻燃剂含量为10%的样品,添加质量分数分别为10%,20%,30%的GF进行增强,同时进行了力学性能测试,并通过DSC、SEM考察了试样的结晶行为及断面的微观形貌,结果表明:随着GF含量的增加,材料的力学性能得到了较大幅度的提高。
Polybrominated ethylene terephthalate (PET) flame retardant composites were prepared by melt blending with brominated polystyrene (BPS) and antimony trioxide (AO) as synergistic flame retardants. The effects of Its flame retardant and mechanical properties. The results show that the composite flame retardant BPS / Sb203 can reach the V-0 level of vertical combustion with the addition of 10%, and the oxygen index reaches 25.4%, but the mechanical properties will be greatly decreased. In order to improve the mechanical properties, the samples with 10% composite flame retardants were selected. The mechanical properties were tested by adding 10%, 20% and 30% GF. The mechanical properties were tested by DSC and SEM The results show that with the increase of GF content, the mechanical properties of the material have been greatly improved.
