2results about How to "Lower energy level" patented technology

The invention discloses a preparation method of a solid propellant containing alkali metal. The preparation method comprises the following steps: step 1, mixing and stirring an adhesive, metal aluminum powder, ammonium perchlorate, alkali metal salt powder, tris (2-methyl-1-aziridine) phosphine oxide and a polymerizing agent to obtain slurry; step 2, carrying out negative pressure pouring on the explosive slurry to obtain an explosive column; and 3, the grain is dried, cured and demolded, and the solid propellant containing the alkali metal is obtained. According to the preparation method, the solid propellant which is relatively rapid in response to microwave energy and relatively efficient is prepared at relatively low cost.
