AI Technical Summary

Technical Problem

Existing EMOFs-based energetic burning rate catalysts in solid propellants have the problem of relatively limited catalytic selectivity, failing to achieve excellent catalytic effects on a variety of propellant components.

Method used

A general-purpose energetic combustion rate catalyst was synthesized by reacting sodium azotetrazole with palladium acetate under specific conditions. The catalyst has a large specific surface area, high thermal stability and multidimensional structure, and is solvent-free, making it suitable for catalyzing various solid propellant components.

Benefits of technology

It significantly advances the thermal decomposition temperature of various existing energetic materials such as AP, RDX, HMX, CL-20 and DAP-4, with excellent catalytic effect, thermal decomposition peak temperature greater than 400℃, and high thermal stability and safety.

Abstract

The application provides a general energetic burning rate catalyst, a preparation method and application, and has a chemical structural formula: sodium azotetrazole salt is dissolved in distilled water and dimethyl sulfoxide to form a reaction solution, palladium acetate is added into the reaction solution, stirring is carried out at room temperature until the reaction solution is clear; then the reaction is sealed and placed at 105 DEG C, after the completion of the placement, the reaction is completed by cooling to room temperature, then filtration is carried out, and the filtrate is filtered out, and the obtained is the general energetic burning rate catalyst. The burning rate catalyst realizes the true "general type", the addition amount is only 2 wt.%, and the catalyst has excellent catalytic effect on five kinds of currently active energetic materials, and is a truly "general type" energetic burning rate catalyst.
