Description

technical field [0001] The invention belongs to the field of propellant and relates to a burning rate catalyst, in particular to a 5-aminotetrazole zinc complex, a synthesis method and an application. Background technique [0002] The burning rate catalyst is one of the components to adjust and improve the combustion performance of solid propellants, and it is a very critical functional material in the formulation of solid propellants. Adding a small amount of burning rate catalyst to the solid propellant formula can reduce the thermal decomposition temperature of the solid propellant components and improve the propellant combustion performance. However, lead-containing compounds are still the most studied types of burning rate catalysts. [0003] On the one hand, lead compounds are extremely important burning rate catalysts in active solid propellants, and their addition increases the propellant burning rate and reduces the pressure index. However, the toxicity of lead co...
