摘　　要：以3-硝基邻苯二甲酸和硝酸氧锆为原料,制备了3-硝基邻苯二甲酸锆,采用元素分析、X射线荧光衍射、FT-IR和TG-DTG对其结构进行了表征。研究了3-硝基邻苯二甲酸锆对双基和RDX-CMDB推进剂燃烧性能的影响。结果表明,3-硝基邻苯二甲酸锆对双基系推进剂燃烧具有良好的催化作用,在低压段能明显提高推进剂的燃速,在中高压段能明显降低燃速压力指数;与铜盐复合后,可显著提高低压段燃速和降低中高压段燃速压力指数。Zirconium 3-nitrophthalate （Zr （3-NO2-PHT） 2 ·2H2O） was synthesized by using 3-nitrophthalic acid, sodium hydroxide, and zirconyl nitrate as raw materials, and the structure was determined by elemental analysis, X ray fluorescence diffraction and FT-IR spectra. The catalytic action of zirconium 3-nitrophthalate on double-base propellant and RDX CMDB propellant was analyzed. The results show thatthe burning rates of the double-base propellant and RDX CMDB propellant increase obviously in the low pressure range, and the pressure exponents of the double-base propellant decrease obviously in the middle and high pressure range. Especially, when Zirconium 3-nitrophthalate together with copper salts is used, the catalytic efficiency is higher.
