Preparation method of pressed aluminum-containing explosive

Abstract

The invention provides a preparation method of a pressed aluminum-containing explosive. According to the preparation method, the pressed aluminum-containing explosive is mainly prepared from 3,4-dinitrofurazanfuroxan and aluminite through direct granulation in the presence of a small amount of additives such as a binder and a desensitizing agent. The method comprises the following steps: firstly, dissolving 3,4-dinitrofurazanfuroxan by using ethyl acetate at a temperature of 50-60 DEG C; then, adding a surfactant, stirring for 20min, and adding the solution into aluminum powder while stirring; and finally, adding a binder and a desensitizing agent solution, stirring for 30min; after the obtained material becomes dough-shaped, sieving so as to form particles with a particle size of 1-2 mm, and drying, thus obtaining the aluminum-containing explosive modeling powder. By using the preparation method of an aluminum-containing explosive provided by the invention, a mixed explosive with good formability and high detonation velocity can be prepared, so that defects in traditional direct preparation methods in the background art are overcome.

Description

Technical field [0001] The present 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 melt-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 desensitizer solution. During the preparation process, the contact between aluminum powder and the main explosive is not sufficient. During th...

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
