Description
Technical Field
The invention relates to a composite propellant taking propynyl polybutadiene as an adhesive and a preparation method thereof, belonging to the technical field of propellant preparation.
Background
Modern composite solid propellants are generally produced by reacting hydroxyl terminated (-OH) polyester and polyether prepolymers with isocyanate (-NCO) to form a polyurethane (-NH-COO-) binder system as a matrix for carrying solid fillers. For polyurethane systems, the isocyanate curative reacts very readily with amino, water, urea, urethane, and the like, as well as the active hydrogens on the hydroxyl groups of the polyester and polyether prepolymers. Wherein, isocyanate reacts with water to generate carbamic acid which is unstable and can be rapidly decomposed into ammonia and carbon dioxide, and pores are easily formed in the propellant, thereby influencing the mechanical property, the storage property and the safety performance of the propellant. Therefore, the propellant is greatly influenced by humidity during production and processing, and the requirement on the water content of each component of the propellant is extremely high. Isocyanate is extremely toxic, the synthesis process is complex and difficult to control, the manufacturing cost is high, the safety requirement is high, and certain pollution is caused to the environment. To better overcome the above disadvantages, the development of other binder systems is one direction in the future of propellant development. By utilizing the click chemistry principle, the CuAAC reaction is adopted to replace the carbamate reaction, and the alkynyl polymer and the azide form a new polytriazole curing system, so that the problems of the traditional solid composite propellant curing system are expected to be solved, and the application range of the solid composite propellant curing system is expanded.
