Abstract

The invention discloses an energy-containing coordination compound with ultrafast self-ignition performance with hydrogen peroxide and a preparation method of the coordination compound. The energy-containing coordination compound is an inorganic-organic hybrid material, and the energy-containing coordination compound provided by the invention is prepared by adopting a simple and convenient one-pot synthesis method. Through the synergistic effect of all the components of the material, the self-ignition performance of the target material is achieved. R is a saturated or unsaturated alkyl chain, and X is a nitrate or cyanoborohydride anion. The self-ignition energy-containing coordination compound provided by the invention has the advantages of short ignition delay time, simple synthesis process, low cost and the like.

Description

technical field [0001] The invention relates to the technical field of energetic materials, in particular to an energetic coordination compound with ultrafast self-ignition performance and a preparation method thereof. Background technique [0002] As the main source of power for engines such as rockets, satellites and missiles, propellants have important applications in the defense industry. In recent years, the rapid development of defense industry technology has put forward higher requirements for the development of propellants. The dual-component self-ignition propellant has the advantage of reliable repeated ignition, and is extremely suitable for space propulsion systems, such as propellers for spacecraft such as satellites and orbit transfer machines. The current commercial self-ignition propellants mainly use the highly toxic and carcinogenic unsymmetrical dimethylhydrazine as fuel, and the highly corrosive N 2 o 4 Or fuming nitric acid as an oxidizing agent. Thi...
