Abstract

The invention discloses a metal azide graphene compound and a preparation method thereof. Soluble metal salt, nano-metal powder or nano-metal oxide is used as a raw material, graphene oxide is used asa conductive carbon material additive, polyvinyl alcohol and the like are used as binders, and the nano-metal azide graphene in any shape is prepared. The azide composite material is prepared by putting several uniformly mixed materials into molds with different shapes and carrying out freeze drying, high-temperature carbonization and in-situ azide reaction. Compared with the traditional azide, the azide graphene initiating explosive obtained by the invention has the advantages that the particle size can reach hundreds of nanometers, the electrostatic sensitivity can be reduced due to the existence of conductive materials such as graphene, and the azide graphene initiating explosive can be designed into different shapes and matched with the charging mode of a micro-initiation system.

[0001] Technical field: The present invention relates to a metal azide graphene composite and a preparation method, using nano metal, nano metal oxide or soluble metal salt as raw material, and a metal azide graphite prepared by a binder shaping method The invention discloses an alkene composite, which belongs to the technical field of energetic materials. Background technique [0002] With the development of new-type ammunition, fuze and other weapon systems towards miniaturization and intelligence, the traditional detonation system cannot meet the current demand due to the large charge volume, large charge amount, and high detonation voltage. The miniaturization and practical application of MEMS (Micro-Electro-Mechanical System) explosives have become one of the main directions of the development of the detonation system, which is accompanied by the miniaturization of its charging system and the change of the charging method. In recent years, nanoscale primers have attracted...
