摘要
利用溶胶-凝胶法制备RDX纳米复合含能材料的干凝胶及气凝胶。采用透射电镜(TEM)和X射线衍射(XRD)对其形貌和晶体结构进行表征,测试了其热分解性能和撞击感度。结果表明,RDX含量为45%的RDX/SiO2纳米复合含能材料气凝胶的DSC分解峰温提前了15.4℃。SiO2凝胶基体可以降低RDX的撞击感度,并且随SiO2基体含量的增大降低幅度增大。
The xerogel and aerogel RDX/SiO2 nanocomposite energetic materials were prepared using sol-gel method. TEM and XRD were used to analyze the surface topography and the crystal structure. The thermal decomposition and the impact sensitivity for RDX/SiO2 nanocomposites were also tested. The results show that compared with pure RDX ,the DSC decomposition peak temperature of the aerogel RDX/SiO2 containing 45% RDX decreases by 15.4 ℃. The xerogel framework can effectively desensitize RDX, and the impact sensitivity descreases greatly with the increase of the SiO2 framework content.
