摘　　要：为了改善和提高超细含能材料的实际使用效果,用超临界流体沉积技术中的超临界反溶剂法(SAS)制备了超细HMX、超细AP、超细HNIW、Al-FPM2602核-壳型复合材料,探讨了工艺条件对该核-壳型复合材料包覆效果的影响,通过单因素试验对影响包覆效果的主要因素进行了研究。试验结果表明,影响包覆效果的主要因素有初始浓度、温度、终点压力。在加入15mL乙酸乙酯、终点压力9.0MPa、温度38℃的条件下,复合材料的吸湿率较小,即复合材料的包覆效果较好。The ultrafine HMX, ultrafine AP, ultrafine HNIW, AI-FPM2602 core-shell composite materials have been prepared by supercritical anti-solvent（SAS） method in order to improve and boost actual use effects. Mixtures of ultrafine HMX, ullrafine AP, ultrafine HNIW and Al have been coated by FPM2602 precipitated on the surface of mixtures. The effect of technical condition on the coating effect of the core-shell composite material is studied. The effect of major factor and performance on the coating effect of the core-shell composite material is studied by means of single factor test and validated. It is proved by experiment that major factors which affect coating effect are primary density, temperature and terminal pressure. On condition that adding volume of ethylacetate is 15mL, temperature is 38℃ and terminal pressure is 9MPa, the hygroscopic coefficient of the composite material is the lowest, that is to say coating effect of the composite material is the best.
