Problems solved by technology

However, lead compounds are highly toxic, 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 missiles. Therefore, it is necessary to develop non-toxic or low-toxic, pollution-free combustion Catalysts become a new topic

Abstract

The invention discloses a 1,8-dihydroxy anthraquinone copper compound as shown in a structural formula (I). The 1,8-dihydroxy anthraquinone copper compound disclosed by the invention has excellent catalysis effect on a modified biradical solid propellant as a combustion catalyst and can outstandingly increase the combustion speed of the modified biradical solid propellant and reduce the pressure index.

Description

technical field [0001] The invention relates to a 1,8-dihydroxyanthraquinone copper compound, which can be used as a combustion catalyst for solid propellants. technical background [0002] In terms of improving the combustion performance of solid propellant formulations, the current common method is to add some compounds as combustion catalysts, which can not only increase the propellant burning rate and reduce the pressure index, but also produce "platform combustion" or "Mesa combustion", etc. Combustion characteristics to adjust the combustion performance of solid propellants. Therefore, the combustion catalyst is an indispensable component in the formulation of the double-base solid propellant, and plays a key role in regulating the combustion performance of the propellant. At present, most double-base propellants use the method of adding a certain amount of composite catalysts composed of lead, copper, and carbon black, and the amount added is generally 1%-5% of the m...
