Abstract

The invention discloses a preparation method of a 2,4,6-triamido-5-nitropyrimidine-1,3-dioxide and hydrogen peroxide self-assembled energetic crystal material. The preparation method comprises the following steps: (1) preparing a hydrogen peroxide saturated aqueous solution of 2,4,6-triamido-5-nitropyrimidine-1,3-dioxide; (2) putting the hydrogen peroxide saturated aqueous solution of the 2,4,6-triamido-5-nitropyrimidine-1,3-dioxide into a flask, then stewing the flask in a constant temperature incubator, evaporating a solvent, sequentially forming a crystal nucleus, enabling crystalline grains to grow, forming a crystal, and filtering and drying the crystal to obtain the 2,4,6-triamido-5-nitropyrimidine-1,3-dioxide and hydrogen peroxide self-assembled energetic crystal. The invention innovatively provides the 2,4,6-triamido-5-nitropyrimidine-1,3-dioxide and hydrogen peroxide self-assembled energetic crystal material.

Description

technical field [0001] The invention belongs to the field of energetic materials, and specifically relates to 2,4,6-triamino-5-nitropyrimidine-1,3-dioxide and hydrogen peroxide self-assembled energetic crystal materials and a preparation method thereof. It has a good application prospect in high-energy explosives. Background technique [0002] Energetic materials are a class of compounds or mixtures composed of oxidants and combustibles that can independently undergo redox chemical reactions and output energy. In traditional energetic compounds such as hexanitrohexaazaisowurtzitane (CL-20) and 1,3,5,7-tetranitro-1,3,5,7-tetraazacyclooctane ( In the construction of HMX), oxidants (such as nitro) and combustible components (such as -CH 2 -skeleton) components are usually integrated in one molecule. But the intrinsic incompatibility of oxidants and combustible components makes the integration of oxidants and combustibles in one molecule very difficult. Typically, an increas...
