Zusammenfassung:The invention relates to a polyurea fast-curing solid propellant 3D printing slurry which is composed of a component A and a component B. The component A comprises 15% of a first adhesive, 70% of an oxidizing agent and 15% of a metal combustion agent. And B comprises 13%-15% of a second adhesive, 69% of an oxidant, 15%-16% of a metal combustion agent and 0%-2% of a functional auxiliary agent. The prepared slurry of the component A and the prepared slurry of the component B are accurately metered and then extruded into a static mixing pipe, after accurate, rapid and uniform mixing of the two materials is achieved, printing of the solid propellant 3D printing slurry is completed according to a designed path, and rapid curing forming is conducted at the room temperature. According to the preparation method, the limitation that a traditional propellant needs to be subjected to follow-up finishing, the production period is long, the percent of pass is low, procedures are tedious, production energy consumption is l
