在介绍1,3-偶极环加成反应的基础上,综述了该反应在聚叠氮基缩水甘油醚(GAP)侧基改性、叠氮化合物固化以及在GAP推进剂中的应用情况。指出了1,3-偶极环加成反应对水分不敏感,使用该方法可以在45~65℃进行推进剂固化,解决固化体系与高能组分的相容性问题,获得感度较低的推进剂;同时也指出该法将体积较大的基团引入侧链中,使推进剂力学性能不够理想,提出了在调节交联密度及其规整性的基础上改善性能的建议。 Based on the introduction of 1,3-dipolar cycloaddition reactions, the modification of pendant polyazide-based glycidyl ethers (GAPs), the curing of azides and the application in GAP propellants are reviewed. It is pointed out that the 1,3-dipolar cycloaddition reaction is insensitive to moisture. Using this method, the propellant can be cured at 45-65 ° C to solve the compatibility problem between the curing system and the high energy component and obtain the lower sensitivity At the same time, it is also pointed out that this method will be bulky groups into the side chain, so that the mechanical properties of the propellant is not ideal, put forward to adjust the crosslinking density and its regularity based on improving the performance of the proposal.
