Abstract

The invention discloses a copper-based suspension, and belongs to the field of energetic materials. The copper-based suspension consists of copper-based powder, polyvinyl alcohol, boric acid and water. A preparation method of the copper-based suspension comprises the following steps: dissolving certain amounts of polyvinyl alcohol and boric acid in water, performing mixing until uniformity, addingcopper oxide or copper powder, stirring for reacting for a certain time, and lowering the temperature to room temperature in order to obtain the copper-based suspension. The copper-based suspension liquid prepared by the method has the characteristics of wide powder content range, good settling resistance, and easiness in solvent removal, and can provide copper oxide and copper powder precursorsfor copper azide and copper-based pyrotechnic composition.

Description

technical field [0001] The invention belongs to the field of energetic materials, specifically relates to a copper-based suspension and a preparation method thereof, and has broad application prospects in priming copper azide and copper-based pyrotechnics. Background technique [0002] Modern warfare has put forward higher and higher requirements for weapon systems, and the miniaturization and intelligence of weapons and ammunition has become one of the main focuses, and the micro-miniature pyrotechnic sequence is the main technical approach. At present, the priming agents commonly used in pyrotechnic sequences include lead azide, lead styphate, dinitrodiazonium phenol, perchloric acid-tetraammonia-bis(5-nitrotetrazole) cobalt, and tricarbon perchlorate. Co-precipitates of cadmium hydrazide, zinc perchlorate tricarbonyl hydrazide, lead basic picrate and lead azide. Compared with other primary explosives, copper azide has the advantages of low limit primary explosive, high o...
