A kind of preparation method of press-packed aluminum-containing explosive

Abstract

The invention provides a method for preparing a press-packed aluminum-containing explosive, which uses 3,4-dinitrofurazanylfuroxan and aluminum powder as main raw materials, and directly Method granulation. The method first dissolves 3,4-dinitrofurazanylfuroxan in ethyl acetate at a temperature of 50°C to 60°C, then adds a surfactant, stirs for 20 minutes, and then adds the above solution to the aluminum powder. Stir as you add. Finally, add the binder and desensitizing agent solution and stir for 30 minutes. After the whole material forms a paste, it is sieved to form particles of 1 mm to 2 mm, and dried to obtain the aluminum-containing explosive molding powder. The mixed explosive with good formability and high detonation velocity can be prepared by adopting the preparation method of the aluminum-containing explosive provided by the invention, which overcomes the defects of the traditional direct preparation method in the background technology.

Description

Technical field [0001] The invention is a method for preparing press-packed aluminum-containing explosives, in particular to a method for preparing aluminum-containing explosives containing 3,4-dinitrofurazanyl furazan oxide (DNTF). Background technique [0002] 3,4-Dinitrofurazanylfuroxan (DNTF) has high detonation velocity and low mechanical sensitivity, and is considered to be the star of high energy density compounds researched and applied in recent years. Because DNTF has a relatively low melting point, it is often used as a carrier for molten-cast explosives, and its preparation method has not been studied in press-packed explosives. The traditional direct method and spray granulation process are prepared by mechanically mixing conventional high-energy explosives in the form of solid particles with aluminum powder, binder and insensitive agent solution. During the preparation process, the contact between aluminum powder and the main explosive is not sufficient, and the expl...

Problems solved by technology

The traditional direct method and spray granulation process are prepared by mechanically mixing conventional high-energy explosives in the form of solid particles with aluminum powder, binder and desensitizing agent solution. During the preparation process, the contact between aluminum powder and the main explosive is not sufficient, and the explosive During the bombardment reaction, the reaction is not complete, which makes the formability and energy output of the mixed explosive low
