摘　　要：以PEG-400为表面活性剂,采用液相分散沉淀法制备出纳米柠檬酸铅,用IR、元素分析、TEM对其结构和铝含量进行了表征。用溶解、稀释、结晶法制备出纳米柠檬酸铅/RDX复合物,用TEM、SEM和TG-DSC对复合物的结构和热分解性能进行了表征。结果表明,纳米柠檬酸铅附着在RDX表面形成复合物,粒径为6～10μm。用ICP测定了复合物中铅质量分数为4.990%,进而推算出复合物中催化剂的质量分数为8.602%。Nano lead(II) citrate was synthesized by liquid dispersion deposition method using PEG-400 as surfactant and characterized by infrared spectroscopy(IR),elemental analysis and transmission electron microscopy(TEM).The nano lead(II) citrate/RDX composite was prepared via a dissolution/dilution/crystallization method.The structure and thermal decomposition properties of the composite was characterized by TEM,SEM and TG-DSC.The results show that nano lead(II) citrate particles attach to RDX and the composite with particle diameter of 6-10μm is formed.The lead content of the composite is 4.990% according to ICP analysis.The content of combustion catalyst in the composite is calculated to be about 8.602%.
