| 摘 要： | 以预聚端羟基叠氮缩水甘油醚(GAP)为软段、4,4′-二苯基甲烷二异氰酸酯(MDI)和1,4-丁二醇(BDO)为硬段,采用熔融预聚二步法合成了一种高能低敏感发射药使用的含能热塑性聚氨酯弹性体(ETPE)。确定了反应时间为2 h,熟化时间为3 d。采用红外光谱(FT-IR)、热重分析(TG)、差示扫描量热(DSC)、力学性能测试、动态热机械分析(DMA)等分析测试技术对ETPE的性能进行了表征。结果表明,当—NCO/—OH物质的量比(R值)为0.98,硬段质量百分含量为40%时,热塑性弹性体的抗拉强度为6.12 MPa,延伸率为71%;在所得ETPE中添加含能增塑剂双(2,2-二硝基丙基)缩甲醛/缩乙醛(BDNPF/A)后,延伸率有所下降。
