Abstract

The invention discloses a ferrocenyl tetrazole metal complex and a preparation method thereof. The ferrocenyl tetrazole metal complex takes Mn<2+>, Co<2+>, Ni<2+>, Cu<2+>, Zn<2+>, Cd<2+> or Pb<2+> as a center metal ion and takes ferrocenyl tetrazole containing a ferrocenyl group and a high azacyclo-tetrazole group as a negative ion, a tetrazole group can improve energy level of a propellant during thermal decomposition, combustion catalysis effect of a ferrocenyl combustion rate catalyst can be improved by virtue of synergistic effect of the metal ion and the ferrocenyl groups, auxiliary ligands are introduced, so that thermal stability of the complex is improved, and combustion catalysis performance of the complex is regulated. The ferrocenyl tetrazole metal complex has good thermal stability, high formation heat and high combustion heat and can realize catalysis and contribute energy to a solid propellant when being used in the solid propellant. The ferrocenyl tetrazole metal complex is simple in preparation method, can be synthesized in the air atmosphere without heating, is low in synthesis cost and high in yield and can be applicable to industrialization application.

Description

technical field [0001] The invention belongs to the technical field of synthesis of combustion regulators in solid propellant formulations, and in particular relates to a ferrocene tetrazolium metal complex and a preparation method thereof. Background technique [0002] Ferrocene and its derivatives, because of their excellent combustion regulation function, have been widely used in strategic and tactical weapon systems as the most important burning rate (combustion) catalysts of solid propellants (especially composite propellants). It plays a huge role in various ballistic missiles (including theater, short-range, medium-range, intercontinental ballistic missiles, etc.), airborne tactical missiles, anti-missile high-speed kinetic energy missiles, sea-based mines, torpedoes and other weapons. [0003] Since the currently used ferrocene-based combustion regulators are easy to migrate, volatile, and low-temperature crystallization problems have not been fundamentally resolved,...
