摘　　要：使用二乙基次膦酸铝(ADP-12)并用协效阻燃剂三聚氰胺氰尿酸盐(MCA)制备无卤阻燃丙烯腈-丁二烯-苯乙烯(ABS)复合材料,使用不同增韧剂对阻燃ABS进行增韧改性,对其阻燃性能及力学性能进行了研究。结果表明,填加增韧剂聚醚型聚氨酯(TPU)制备的阻燃ABS合金综合阻燃性能最优,氧指数达到33.6%,垂直燃烧显示出V-1级别;SBS对阻燃ABS增韧效果最好,制备的阻燃苯乙烯-丁二烯-苯乙烯嵌段共聚物(SBS)/ABS合金力学性能最优,冲击强度、断裂伸长率均比未填加增韧剂的阻燃ABS有所提高;通过偏光显微镜发现,阻燃剂在TPU/ABS合金中阻燃剂分散较好,但仍有团聚现象存在。Halogen free flame retardant ABS composite material was prepared with synergistic flame retardant ADP-12 and MCA.By using different toughing agents to modify the halogen free flame retardant ABS composite,the flame retardant and mechanical properties of the ABS alloy were investigated.The results showed that halogen free flame retardant TPU/ABS alloy had best overall performance in flame resistance,the limiting oxygen index（LOI）of the ABS was 33.6% and the vertical flame test rating was V-1.SBS had a best toughing effect on the halogen free flame retardant ABS.The impact strength and elongation at break of SBS/ABS alloy were significant higher than the halogen free flame retardant ABS.PCM images proved that flame retardant had better dispersion in the halogen free flame retardant TPU/ABS alloy,but reunion of flame retardants still exist.
