摘　　要：选择不同种类、不同浓度的聚乙烯吡咯烷酮K90和司班80作为晶形控制剂，采用溶剂-非溶剂法制备CL-20。分析了晶形控制剂对六硝基六氮杂异伍兹烷（CL-20）晶体的影响机理，用偏光显微镜和粒度分析仪表征CL-20的粒度、形貌及团聚现象；最后用X射线衍射仪对其晶型进行了表征。结果表明：不同种类、不同浓度的晶形控制剂对晶体形貌的影响有很大差别，聚乙烯吡咯烷酮K90效果最好，在其质量浓度为0．015%时得到粒度在1～10μm之间、分布均匀、表面光滑的ε-CL-20晶体。Different species and different concentrations of PVP K90 and Span 80 were chosen as crystal modifi-ers, and the CL-20 was prepared by recrystalization with solvent-nonsolvent method. The influence mechanism of the crystal modifiers were analyzed, the particle size, morphology and agglomeration of CL-20 crystals were re-searched by polarizing microscope and laser particle size analyzer, at last the crystal type of the CL-20 was identied by XRD. The results show that the different crystal growth modifiers on the crystalline morphology has a great influ-ence, pvpK90 effect is best, when its mass concentration of 0. 015% for CL-20 refine crystal grain size between 1~10 microns, and the smooth surface of ε-CL-20 crystals.
