Energetic crystal material obtained through self-assembly of melamine nitrogen oxide and oxidant and preparing method thereof

Abstract

The invention discloses a preparing method of an energetic crystal material obtained through self-assembly of a melamine nitrogen oxide and an oxidant. The preparing method comprises the steps of 1, preparing the melamine nitrogen oxide, wherein a sufficient amount of melamine is added to an appropriate amount of trifluoroacetic acid to be dissolved, an aqueous hydrogen peroxide solution is addeddropwise, reaction and filtering are conducted to obtain a white precipitate, the white precipitate is dissolved in an appropriate amount of water, alkaline is added to neutralize the solution to keepthe pH value at 7, and filtering is conducted to obtain the melamine nitrogen oxide; 2, preparing the energetic crystal material, wherein the melamine nitrogen oxide is dissolved in the aqueous hydrogen peroxide solution, nitric acid or perchloric acid separately, and through a series of operation, the energetic crystal material obtained through self-assembly of the melamine nitrogen oxide and the oxidant is obtained. The energetic crystal material obtained through self-assembly of the melamine nitrogen oxide with hydrogen peroxide, nitric acid and perchloric acid has the advantages of beingsimple in preparing technology, low in raw material cost, high in density and detonation performance and proper in sensitivity, and is a high-energy explosive with high potential application value.

Problems solved by technology

[0003] General high-energy energetic compounds, such as hexanitrohexaazaisowurtzitane (CL-20) and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane ( HMX), has higher cost of raw materials, more complex preparation process, and oxidant (such as nitro) and combustible components (such as -CH 2 -Skeleton) components are usually integrated in one molecule, and there are defects such as the contradiction between energy and sensitivity that is difficult to effectively reconcile

Therefore, it is not suitable for some fields that have strict requirements on energy and sensitivity.
