Abstract

The invention provides a ferrocenyl macrocyclic composite combustion rate catalyst and a preparation method and application thereof. According to the ferrocenyl macrocyclic composite combustion rate catalyst and the preparation method and application thereof, a simple supramolecular host-guest assembly method is utilized, the ferrocenyl macrocyclic composite combustion rate catalyst is prepared through host-guest inclusion, so the molecular weight of a micromolecular ferrocenyl combustion rate catalyst is increased; by combining the stability of the macrocyclic compound and the supramolecular effects of hydrogen bonds, hydrophilicity, hydrophobicity and the like of the macrocyclic compound and propellant components, the sublimation and migration properties of the ferrocene burning rate catalyst are greatly reduced, the stability of the ferrocene burning rate catalyst during curing processing in the propellant is improved, and the storage application performance of the ferrocene burning rate catalyst in the propellant is effectively improved.

Description

technical field [0001] The invention relates to the technical field of solid propellants, more specifically, it relates to a ferrocene-based macrocyclic composite burning rate catalyst and its preparation method and application. Background technique [0002] Solid propellants provide a vital source of power for missiles, rockets, aircraft, and more in aerospace and military applications. Burning rate catalyst (abbreviation: burning rate catalyst) is an indispensable component in the solid propellant formula, which can realize the controllable adjustment of the burning rate and pressure index of the solid propellant. Ferrocene-based compounds are considered to be burn-rate catalysts with excellent comprehensive performance. They have the advantages of excellent combustion catalytic performance, good mechanical properties, and high component compatibility, and are widely used as burn-rate catalysts for solid propellants. Among them, the most representative one is the burning ...
