Abstract

The invention discloses a 1,4,5,8-tetrahydroxyanthraquinone copper compound. The 1,4,5,8-tetrahydroxyanthraquinone copper compound is prepared by the following steps: reacting 1,4,5,8-tetrahydroxyanthraquinone serving as a raw material with monovalent alkali metal hydroxide to obtain a 1,4,5,8-tetrahydroxyanthraquinone monovalent metallic compound; reacting with cupric salt to obtain the 1,4,5,8-tetrahydroxyanthraquinone copper compound. The structural formula of the 1,4,5,8-tetrahydroxyanthraquinone copper compound is shown in specification. The 1,4,5,8-tetrahydroxyanthraquinone copper compound is mainly applied to an improved double-base propellant as a combustion catalyst.

Description

technical field [0001] The invention relates to a catalyst for solid propellants, in particular to a 1,4,5,8-tetrahydroxyanthraquinone copper compound and its preparation method and application. technical background [0002] In terms of improving the combustion performance of double-base propellants or modified double-base propellant formulations, the current common method is to adjust the burning rate and pressure index of the propellant by adding some metal salts as combustion catalysts. 1%-5%. [0003] Lead compounds are the most important catalysts for the practical application of double-base propellants today, but lead compounds are highly toxic, and the lead oxide produced by combustion and decomposition is white or light blue smoke in the engine exhaust, which is not conducive to the guidance of missiles And stealth, which is inconsistent with modern weapons requiring propellants with low signature. Therefore, the development of non-toxic or low-toxic, non-polluting...
