Preparation and Properties of TKX-50/AP Composite Microspheres
摘要
Abstract
To obtain new energetic materials with high energy,low sensitivity and liable storage,TKX-50/AP composite micro-spheres were prepared by spray drying method.The effects of different feed rates on the morphology of composite microspheres were investigated,and the optimum process conditions were obtained.The morphology and crystal form of the samples were characterized by scanning electron microscope,X-ray diffractometer and Fourier infrared spectrometer.The thermal decomposi-tion performance,impact sensitivity and hygroscopicity of the microspheres were also studied.Results show that the samples are spherical particles with sphericity of Φ=96.40%and d50=1.33 μm at the feed rate of 3.6 mL·min-1.The crystal structure is differ-ent from that of mechanical mixing of TKX-50 and AP.The thermal decomposition activation energy is 184.43 kJ·mol-1,the char-acteristic drop is 50.1 cm,and the hygroscopicity is 37%lower than that of the physical mixing,showing excellent safety perfor-mance.关键词
