摘　　要：键合剂是改善黑索金(RDX)、奥克托金(HMX)等硝胺和氧化剂填料与黏合剂间界面作用的关键功能材料,也是提高推进剂力学性能的有效、方便、实用的策略。综述复合推进剂中硼酸酯(BEBA)与中性聚合物(NPBA)等键合剂的研究进展,归纳了键合剂的作用机理,梳理了当前和未来高性能推进剂用键合剂的发展动向,针对不同的黏合剂体系和新的固化方式等发展趋势,设计具有多种功能基团的键合剂结构,积极开发可同时与硝胺、氧化剂及黏合剂相匹配的键合剂,进一步完善补充键合机理,以满足高新武器系统对高力学性能推进剂的需求。Bonding agent is the crucial functional material to improve the interfacial interaction of filler and binder,and the effective,convenient and practical strategy to improve the mechanical properties of propellants.This review summarizes the development of borate ester bonding agent(BEBA)and neutral polymeric bonding agent(NPBA),generalizes the bonding mechanism and teases the development trends of bonding agent applied to composite solid propellants.We conclude that bonding agent with multiple functionalities should be designed for different binder systems and curing ways to match the nitramine,oxidizer and binder.The bonding mechanism should be supplemented to meet the need of high-tech weapon system towards the high mechanical properties of propellants.
