摘　　要：采用国产热塑性聚氨酯弹性体(TPU)、氯化聚乙烯(CPE)在TPU/CPE二元共混改性体系的基础上,添加自行复配研制的膨胀型阻燃剂(IFR),对所构成的TPU/CPE/IFR进行了研究。结果表明:TPU/CPE/IFR阻燃体系阻燃性可达到FV-0级(IFR为19.2份),并具有较好的力学性能;该阻燃体系的拉伸强度、断裂伸长率分别保持了TPU/CPE的56%和73%。TPV/CPE/IFR体系随着IFR用量的增加,流动性变好。TPU/CPE/IFR flame retardance systems compositing by domestic TPU,CPE and compounded intumescent flame retardants（IFR） were researched. The results show that TPU/CPE/IFR systems reach FV-0（IFR is19.2 phr）. At the same time, TPU/CPE/IFR has good mechanical properties. In comparison with TPU/CPE, its stretch intensity decreases by 44% ,and is split elongation decreases by 27 %. TPU/CPE/IFR flow properties get better with increasing the content of IFR.
