摘　　要：以F_(2602)(氟橡胶)为胶粘剂、HMX(奥克托今)为含能材料,采用喷雾干燥法制备了PBX(聚合物粘接炸药)。利用SEM(扫描电镜)、XRD(X-射线衍射)法和DSC(差示扫描量热)法对PBX的结构和性能进行了表征。研究结果表明:HMX/F_(2602)复合炸药的颗粒呈球形状结构,并且其粒径达到纳米级别;与HMX原料相比,HMX/F_(2602)的热稳定性更好,撞击感度明显降低[H_(50)(特性落高)值由18.20 cm升至35.37 cm]。With F（2602）（fluorine rubber）as adhesive,HMX as energetic material,the PBX（polymer bondedexplosive） was prepared by spray drying method. The structure and properties of PBX were characterized bySEM（scanning electron microscope）,XRD（X-ray diffraction）method and DSC（differential scanning calorimetry）method. The research results showed that the HMX/F（2602） composite explosive particles had the spherical structure,and its particle size reach nanoscale. Compared with HMX raw material,the HMX/F（2602） had the betterthermostability,and its impact sensitivity was obviously reduced because its H（50）（features fall- high）value wasincreased from 18.20 cm to 35.37 cm.
