    • PURPOSE: A curing agent for a solid propellant composition is provided to prevent mass transfer of a low molecular weight hardener by reacting the low molecular weight hardener with a prepolymer. CONSTITUTION: A curing agent for a solid propellant composition is represented by chemical formula(1). A method for manufacturing a polymer hardener comprises a step of performing reaction so that the equivalence ratio of an isocianate functional group of a compound with a diiosocianate group and a hydroxyl group of a hydroxyl-terminated prepolymer is NCO/OH = 1.9-2.1. The solid propellant composition includes prepolymer 2-25 weight%, oxidation stabilizer 0.1-1 weight%, solid filler 40-90 weight%, polymer hardener 3-35 weight% and curing catalyst 0.001-0.2 weight%.
    • 目的:提供固体推进剂组合物的固化剂,以通过使低分子量固化剂与预聚物反应来防止低分子量固化剂的传质。 构成:固体推进剂组合物的固化剂由化学式(1)表示。 聚合物硬化剂的制造方法包括进行反应的步骤,使得化合物的异山梨酸酯官能团与二硫代邻苯二甲酸酯基和羟基封端的预聚物的羟基的当量比为NCO / OH = 1.9-2.1。 固体推进剂组合物包括预聚物2-25重量%,氧化稳定剂0.1-1重量%,固体填料40-90重量%,聚合物硬化剂3-35重量%和固化催化剂0.001-0.2重量%。
