摘　　要：采用国产TPU、CPE,在TPU/CPE二元共混改性体系的基础上,添加膨胀型阻燃剂HT931,对所构成的TPU阻燃体系进行了研究。结果表明:TPU/CPE/HT931阻燃体系有较好的阻燃性能,可达到FV0级(HT931=15份),并有较好的力学性能,与纯TPU相比,该体系的拉伸强度保持了纯TPU拉伸强度的67%,断裂伸长率保持了纯TPU断裂伸长率的80%,流动性变好。TPU flame-retarded systems composited by domestic TPU、CPE and additive flame-retarded alloy HT-931 were investigated.The results indicated that TPU/CPE/HT-931 flame-retarded systems reached FV-0(HT-931=15phr),and had good mechanical properties.The tensile strength got 67% of that of pure TPU,and its break elongation had 80% of that of pure TPU,meanwhile its flow properties became better.
