| 摘 要： | 运用透射电镜（TEM）和动态力学分析（DMA）研究了丁羟推进剂粘合剂体系的形态结构,发现在该体系中存在硬段、软段两相分离结构；防老剂H（N,N’-二苯基对苯二胺）的加入,引入了更多的硬段微区,使两相结构更为清晰；解释了防老剂H能大幅度提高粘合剂体系力学性能的原因。

| Abstract: | The morphological structures of HTPB propellant binders have been studied bytransmission electron microscopy (TEM ) and dynamic mechanical analysis (DMA). It is found thatthere are microphase segregation structures of hard and soft segments in the binders. Harder segmentdomains are brought in binders by adding antioxidant H (N, N'-diphenyl-p-phenylene dlamine)andthe microphase segregation structures become clearer. We have explained the reason that antioxidantH can greatly improve mechanical properties of HTPB propellant binders. |
