摘　　要：为解决温压炸药中铝粉反应效率较低的问题,采用胶体研磨方法将助燃剂添加到铝粉中,对助燃剂与铝粉的混合物进行了表征,并用TG-DSC和简易点火装置研究了助燃剂对铝粉高温氧化过程和点火温度的影响规律,设计了几种炸药配方,验证了含助燃剂的铝粉在炸药中的使用效果。结果表明,胶体磨研磨工艺可将助燃剂与铝粉混合均匀,聚四氟乙烯、氧化铜、三氧化二铁、镍和硼均具有一定的助燃作用。To solve the low reaction efficiency of aluminum powder in thermobaric explosive,some aluminum accelerants were selected.The combustion-support role and the properties of these accelerants and their mixture with aluminum and the influence law of accelerants on the high temperature oxidation process and ignition temperature of aluminum powder obtained by differential thermal analyzer(TG-DSC)and the simple ignition device were studied.Several explosive formulas were designed and the applied effect of aluminum containing accelerant in explosive was verified.The result shows that accelerant and aluminum powder can be mixed up by colloid mill,PTFE,CuO,Fe2O3,Ni and boron can play a certain combustion-support role and improve the energy of explosive.
