摘要
针对海军战术导弹固体火箭发动机端羟基聚丁二烯(hydroxyl-terminatedpolybutadiene,HTPB)推进剂老化问题,对HTPB推进剂粘结体系的老化及防护进行探讨。对丁羟聚氨酯热氧老化机理及影响因素进行介绍,分别从物理防护与防老剂的化学防护2方面概述了HTPB推进剂粘结体系的防护。从老化实验、仪器分析及分子模拟3方面对老化及防护的研究方法进行了总结,并对分子模拟技术在HTPB推进剂老化及防护研究的应用前景进行展望。该研究对未来HTPB推进剂的防老化及导弹贮存、使用性能的提高有一定指导意义。
Aiming at the aging problem of hydroxyl-terminated polybutadiene(HTPB) propellant in solid rocket engine of naval tactical missile, the aging and protection of HTPB propellant binder system were discussed. The thermal-oxidative aging mechanism and influencing factors of HTPB polyurethane were introduced, and the protection of HTPB propellant binder system was summarized from 2 aspects: physical protection and chemical protection of antioxidant. The research methods of aging and protection were summarized from 3 aspects: aging experiment, instrumental analysis and molecular simulation, and the application prospect of molecular simulation technology in the aging and protection of HTPB propellant was prospected. This study has a certain guiding significance for the future anti-aging of HTPB propellant and the improvement of missile storage and use performance.
