Abstract

The invention discloses a ferrocene high-nitrogen energetic eutectic. The ferrocene high-nitrogen energetic eutectic is an eutectic formed by using N,N-dimethylaminomethylferrocene and an energetic compound, wherein the energetic compound is tetrazole, picric acid, trinitrotoluene or 5-aminotetrazole. The ferrocene high-nitrogen energetic eutectic is synthesized through eutectic formation of the energetic compound and a ferrocene burning rate catalyst N,N-dimethylaminomethylferrocene through using an eutectic technology, so a synthetic method of the eutectic has the advantages of simplicity and low cost; and the synthesized ferrocene high-nitrogen energetic eutectic has the advantages of non-volatility and good heat stability under natural conditions, high formation heat and combustion heat, great reduction of the migration and the volatility of the catalyst, and improvement of the energy level of a propellant during decomposition due to energy containing of the eutectic.

Description

technical field [0001] The invention belongs to the technical field of synthesis of burning rate catalysts in solid propellant formulations, and in particular relates to a ferrocene high-nitrogen energy-containing eutectic compound and a preparation method thereof. Background technique [0002] Burning rate catalysts, also known as combustion modifiers, are one of the essential components in solid propellant formulations. Among the many burning rate catalysts, ferrocene burning rate catalysts are widely used in composite solid propellants due to their excellent combustion regulation function, in various ballistic missiles, airborne tactical missiles, anti-missile high-speed kinetic energy missiles and Sea-based mines, torpedoes and other weapons play an important role. However, ferrocene-based burning rate catalysts have the defects of volatilization and sublimation in the production of solid propellants, and there are problems of easy migration during storage.
