Problems solved by technology

However, this type of substance has high toxicity, and the lead oxide produced by burning and decomposing is white or light blue smoke in the engine exhaust, which is not conducive to the guidance and stealth of the missile. Therefore, it is necessary to develop non-toxic or low-toxic, non-polluting Green combustion catalyst has become an important development direction of catalyst
The 1,8-dihydroxyanthraquinone copper inert combustion catalyst reported in Chinese invention patent 201310637571.1 can adjust the combustion performance when added to the modified double-base propellant formula, but it also reduces the energy level of the solid propellant
This catalyst can only make the burning rate of the modified double base propellant at 10MPa about 15.52mm / s

Abstract

The invention discloses a 1,8-dyhydroxy-4,5-dinitroanthraquinone copper compound. A preparation method of the 1,8-dyhydroxy-4,5-dinitroanthraquinone copper compound comprises the following step: carrying out double-decomposition reaction on 1,8-dyhydroxy-4,5-dinitroanthraquinone as a raw material, and bivalent copper salts to prepare the 1,8-dyhydroxy-4,5-dinitroanthraquinone copper compound, wherein the structural formula of the 1,8-dyhydroxy-4,5-dinitroanthraquinone copper compound is as shown in the specification. The 1,8-dyhydroxy-4,5-dinitroanthraquinone copper compound is mainly applied to a double-base solid propellant as a green combustion catalyst.

Description

technical field [0001] The invention relates to a combustion catalyst for a solid propellant, in particular to a 1,8-dihydroxy-4,5-dinitroanthraquinone copper compound and a preparation method and application thereof. technical background [0002] Combustion catalyst is one of the important components of solid propellant functional materials. It is mainly used to adjust the combustion performance of solid propellant (such as burning rate, pressure index, burning rate temperature coefficient, etc.), and the addition amount in solid propellant formula is generally 0.5%-3% of the mass fraction. At present, the combustion catalysts commonly used in double-base solid propellants are mainly organic lead compounds such as lead rexolate, lead salicylate, and lead stearate. However, this type of substance has high toxicity, and the lead oxide produced by burning and decomposing is white or light blue smoke in the engine exhaust, which is not conducive to the guidance and stealth of ...
