摘要
基于固体推进剂的贮存老化,以NEPE推进剂和以HTPB推进剂为代表,综述了近年来固体推进剂老化进程中所受的各种影响因素、作用机制及化学反应机理研究进展。总结了温湿度、应力和环境气氛为代表的外部环境因素,配方性质、组分变化和添加剂等内部影响因素对推进剂老化及贮存失效期限的影响。分别从微观和宏观角度出发,分析了内外部各种影响因素加速或减缓固体推进剂老化进程的作用机制。此外,针对黏合剂、氧化剂、防老剂等化学组分,总结了固体推进剂贮存老化期间发生的氧化交联、分解、降解断链等主要化学反应,并分析了各个反应发生的机理及原因。最后,展望了未来固体推进剂老化影响因素研究的发展趋势,并为今后固体推进剂老化机理及失效模式研究提供了研究思路。
Based on storage aging of solid propellants,the research progress of various affecting factors,action mode and chemical reaction mechanism on the aging process of solid propellants in recent years is reviewed with NEPE propellants and HTPB propellants as the representatives.The effects of external environmental factors such as temperature and humidity,stress and ambient atmosphere,formula properties,composition changes and additives on propellant aging and storage failure time are summarized.The mechanism of internal and external factors to accelerate or slow down the aging process of solid propellant is analyzed from micro and macro perspectives.In addition,the oxidative crosslinking,decomposition and chain breaking of chemical components such as adhesives,oxidants and antioxidants during propellant aging are summarized,and the mechanism and reasons of each reaction are analyzed.Finally,the future development trend of the research on the affecting factors of solid propellant aging is prospected,and the research routes for the research on the aging mechanism and failure mode of solid pro-pellant in the future are provided.
