摘要:

以没食子酸、硝酸氧锆和硝酸铜为原料,首次合成出了没食子酸锆(Gal-Zr)和双金属有机盐———没食子酸锆铜(Gal-ZrCu),采用有机元素分析、X 射线荧光光谱(XRF)、傅里叶变换红外 (FTIR)光谱和TG-DTG 对其进行了表征。利用螺压工艺制备了含Gal-Zr 和Gal-ZrCu 的推进剂样品,研究了Gal-Zr 和Gal-ZrCu 对双基系推进剂燃烧性能的影响,分析了其燃烧催化作用。结果表明,Gal-Zr 和Gal-ZrCu 对双基推进剂的燃烧具有良好的催化作用,是一种高效、新型绿色燃烧催化剂。但是,Gal-Zr 或Gal-ZrCu 对RDX-CMDB 推进剂的燃烧没有产生明显的催化作用。

Abstract:

Zirconium gallate (Gal-Zr) zirconium/ copper gallate (Gal-ZrCu) were synthesized firstly by using gallic acid, zirconyl nitrate and copper nitrate as raw materials, and was characterized by elementary analysis, X-ray fluorescence diffraction ( XRF ), Fourier transform infrared ( FTIR ) spectroscopy and TG-DTG technique. The sample of propellants containing Gal-Zr and Gal-ZrCu were prepared by extrusion technology, and the effects of Gal-Zr and Gal-ZrCu on combustion properties of DB/ CMDB propellants were investigated. The results show that Gal-Zr and Gal-ZrCu are excellent and environmental-friendly catalysts, and they possess good catalytic effect on combustion of DB propellant. However, the results indicate that Gal-Zr or Gal-ZrCu is not ideal.

Key words: physical chemistry, zirconium gallate, zirconium/ copper gallate, double-base propellant, RDX-CMDB propellant, combustion property, catalytic activity
