摘　　要：固体推进剂和衬层配方的固化体系对其本体性能以及两者界面的黏结性能具有非常重要的影响,端羟基聚丁二烯(HTPB)和异氰酸酯是丁羟固体推进剂和衬层固化体系中最主要的组分。综述了HTPB-异氰酸酯体系的固化反应机理以及催化剂、固化剂种类和固化参数等因素对固化反应的影响。The curing systems of solid propellant and liner formulation have significant effects on its bulk performance and their interface bonding performance. Hydroxyl-terminated polybutadiene （HTPB） and isocyanate are the most main components of the curing systems based on the HTPB solid propellant and liner. The curing reaction mechanism of HTPB-isocyanate system and the influence of the factors such as the types of catalyst and curing agent as well as curing parameters, etc. on the curing reaction are reviewed.
