摘    要:以酒石酸、硝酸氧锆和硝酸铅为原料,合成出了双金属盐酒石酸铅锆,采用有机元素分析、X射线荧光光谱和FTIR对其进行了表征。在程序升温条件下,利用TG/DTG、DSC、固相原位反应池/FTIR联用技术,研究了酒石酸铅锆的热行为和热分解机理,描述了酒石酸铅锆的热分解过程,分析得出其最终分解产物为ZrO2、PbO和C。利用螺压工艺制备了含酒石酸铅锆的推进剂样品,研究了酒石酸铅锆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,酒石酸铅锆对双基系推进剂的燃烧具有良好的催化作用,是一种高效的燃烧催化剂;酒石酸铅锆热分解的最终产物PbO是催化燃烧的主要活性物质,推进剂燃烧过程中形成了氧化铅-铅循环催化体系,而锆和碳则起辅助催化的作用。

关 键 词:材料科学  酒石酸铅锆  推进剂  热行为  分解机理  燃烧性能  催化作用

Abstract:Lead/zirconium tartrate (Tar-PbZr) was synthesized firstly by using tartrate acid, zirconyl nitrate and lead nitrate as raw materials, and was characterized by elementary analysis, X-ray fluorescence diffraction and FTIR spectra. The thermal behavior and decomposition mechanism of Tar-PbZr in a temperature-programmed mode have been investigated by means of TG/DTG, DSC and condensed phase thermolysis/FTIR techniques. The thermal decomposition process of Tar-PbZr have been obtained, and the results show that the decomposition products of Tar-PbZr were ZrO2, PbO and C. The sample of propellants containing Tar-PbZr were prepared by extrusion technology, and the effects of Tar-PbZr on combustion properties of DB/CMDB propellants were investigated. The results show that Tar-PbZr is an excellent catalyst, and it possesses good catalytic effect on combustion of DB propellant and RDX-CMDB propellant.
Keywords:materials science  lead/zirconium tartrate  propellant  thermal behavior  decomposition mechanism  combustion property  catalytic activity
