摘要:
鉴于含铝炸药（钝黑铝，DHL）在安全性和能量输出方面存在问题，使用不敏感单质炸药FOX-7(1,1-二氨基-2,2-二硝基乙烯)作为主体炸药，并以高纯度超细无定形硼粉（B）作为高能燃料、高氯酸铵（AP）作为氧化剂和产气剂、乙烯-醋酸乙烯共聚物（EVA）为黏结剂、微晶蜡作为钝感剂，基于相关理论进行配方设计与优化。最终，采用以撞击感度为判据的配方，并通过湿法球磨辅助溶剂蒸发法制备出混合炸药。该炸药具有如下主要性能：堆积密度1.469 g/cm3，撞击感度10%，摩擦感度12%，爆热8 092.9 kJ/kg，5 s延滞期爆发点303 ℃，真空安定性合格，热安定性良好。由此可得，该炸药是一种可替代DHL炸药的不敏感高能炸药。
Abstract:
Aluminum containing explosives (dull black aluminum, DHL) have issues with safety and energy output. An insensitive single-compound explosive FOX-7 (1,1-diamino-2,2-dinitroethylene) was used as the main explosive, high-purity ultrafine amorphous boron powder (B) was used as the high-energy fuel, ammonium perchlorate (AP) was used as the oxidant and gas generator, ethylene vinyl acetate copolymer (EVA) was used as the binder, and microcrystalline wax was used as the desensitizer. Based on relevant theories, the optimization design of the explosive formula was carried out. Finally, a formula based on impact sensitivity was adopted, and a mixed explosive was prepared by wet ballmilling-assisted solvent evaporation method. The packing density of this explosive is 1.469 g/cm3, with an impact sensitivity of 10%, a friction sensitivity of 12%, a detonation heat of 8 092.9 kJ/kg, and a five-second delay period of 303 ℃. Vacuum stability of the explosive is qualified, and the thermal stability is good. Therefore, this explosive is an insensitive high-energy explosive that can replace DHL explosives.
