摘要/Abstract

摘要： 采用HLG-50型粉碎机，成功制备了亚微米六硝基六氮杂异伍兹烷（CL-20）。运用激光粒度仪和扫描电子显微镜(SEM)对产品的粒度分布、颗粒大小及形貌进行了表征；采用傅里叶变换红外光谱(FT-IR)、激光拉曼光谱(Raman)、X射线粉末衍射(XRD)仪及高效液相色谱(HPLC)仪分析了产品的晶型和纯度；使用热重(TG)和差示扫描量热(DSC)法分析其热分解特性，同时表征了产品的冲击波感度。研究结果表明：亚微米CL-20颗粒呈类球形，其平均粒径d₅₀为210 nm，并保持着原料的ε晶型且纯度高；与原料相比，亚微米CL-20的热分解峰温度稍有提前，其冲击波感度下降了53.1%，降感效果明显，有利于CL-20的应用。

Abstract: Submicron hexanitrohexaazaisowurtzitane (CL-20) is prepared using HLG-50 pulverized machine. The laser particle size analyzer and SEM are used to characterize the particle size, size distribution and morphology of sample. The polymorph and purity of CL-20 particles are characterized by Fourier transform infrared spectrometer, laser Raman spectrometer, XRD and HPLC, respectively. The TG/DSC simultaneous thermal analyzer is used to study the thermal decomposition of CL-20. The shock sensitivity of samples are studied. The results show that CL-20 particles are pseudo-spherical with an average particle size (d₅₀) of 210 nm. The polymorph of submicron CL-20 is consistent with that of the raw ε-CL-20. Compared with the raw CL-20, the thermal decomposition peak temperature of the submicron CL-20 is decreased slightly, and the shock sensitivity of the submicron CL-20 is considerably reduced by 53.1%. That implies the obvious reduction in the shock sensitivity of CL-20.

Key words: ordnance science and technology, CL-20, mechanical pulverization, shock sensitivity, sensitivity reduction mechanism
