Abstract

The invention discloses a composite coating agent for ammonium perchlorate ultrafine particles and a preparation method of the composite coating agent. The composite coating agent is prepared from the following components in parts by weight: 100 parts of sodium polyalkyl sulfate, 7.0-9.0 parts of triethanolamine and 1.5-2.5 parts of isopropanolamine. And the three components are compounded for use, so that the coating effect can be remarkably improved. The ammonium perchlorate ultrafine particles prepared by the method are regular in surface morphology, good in dispersity and not prone to caking, and the comprehensive performance of a composite solid propellant can be effectively improved.

Description

technical field [0001] The invention belongs to the field of superfine powder surface modification, in particular to a composite coating agent for ammonium perchlorate superfine particles and a preparation method thereof. Background technique [0002] Ammonium perchlorate (AP) is the most commonly used oxidant in solid propellants. It has excellent properties such as high oxygen content, good thermal and chemical stability, and no solid residue after thermal decomposition. In different types of propellants such as double-base modified propellants and composite solid propellants, AP is usually used as an oxidant and the main energy substance, and the added mass fraction can reach 70% to 90%. However, due to factors such as irregular microstructure, poor conventional dispersion, and unstable combustion performance, its further development in propellants is restricted. In order to improve the comprehensive performance of propellants, the method of refining AP is widely used at...
