Benzoate-based burning rate catalyst containing dinuclear ferrocene group and preparation method of benzoate-based burning rate catalyst

Abstract

The invention discloses a benzoate-based burning rate catalyst containing a dinuclear ferrocene group and a preparation method of the benzoate-based burning rate catalyst. A structural formula of theburning rate catalyst is as shown in the specification. The burning rate catalyst provided by the invention is unlikely to migrate or volatilize under natural conditions, is good in thermal stability,and has relatively high formation heat and combustion heat due to the introduction of a nitrogen-rich group; the energy level of a solid propellant is increased when the burning rate catalyst is usedin the solid propellant during combustion; and the burning rate catalyst has a relatively good combustion catalysis effect on main components of the solid propellant, namely ammonium perchlorate andcyclonite. The burning rate catalyst provided by the invention has the advantages that the preparation method is simple to operate, the synthesis cost is low, and the defects of complicated synthesisprocess, high price, high cost and the like of the existing ferrocene and derivatives thereof are overcome.

Description

technical field [0001] The invention belongs to the technical field of solid propellants, in particular to a class of benzoic acid ester burning rate catalysts containing dinuclear ferrocene groups, and a preparation method for the burning rate catalysts. Background technique [0002] Solid propellant (solid gunpowder) has gradually developed as a composite type of energetic material for the purpose of propulsion. It mainly provides driving force for rockets, shells, guns, and missiles, and plays an important role in the development of missile and aerospace industries. It plays a very important role. Its performance plays a decisive role in the combat capability of weapons and missiles, and it occupies an important position in national defense science and technology. In order to ensure the ballistic performance of the solid rocket motor and the stable operation of the motor, most strategies and tactics hope that the burning rate pressure index of the solid propellant is low....
