复合固体推进剂黏合剂研究进展

Research progress of composite solid propellant binders

综述了端羟基丁二烯(HTPB)、端羟基共聚醚(HTPE)、聚缩水甘油叠氮醚(GAP)、聚3-硝酸酯甲基-3-甲基氧杂环丁烷(PNIMMO)和聚缩水甘油硝酸酯(PGN)等几种主要黏合剂近十年的发展概况。强调优化固化体系、完善黏合剂网络结构以及嵌段改性是当前黏合剂发展的主要策略和技术手段。同时,提出随着纳米科技、高分子合成与改性新技术以及超分子化学的蓬勃发展,自修复和3D打印技术已经成为引领黏合剂发展的前沿领域。

The development of several main binders in the recent ten years,such as hydroxyl terminated polybutadiene(HTPB),hydroxyl terminated copolyether(HTPE),glycidyl azide polymer(GAP),poly(3-nitratomethyl-3-methyloxetane)(PNIMMO),and polyglycidyl nitrate(PGN)was reviewed. It was emphasized that optimizing the curing system,improving the binder network structure and block modification were the main strategies and techniques for the development of binders. At the same time,it was proposed that with the vigorous development of nanotechnology,new technologies of polymer synthesis and modification,and supramolecular chemistry,self-healing and 3 D printing technology had already been at the cutting edge of the binder development.
