摘　　要：为解决当前低爆速爆炸焊接炸药混合均匀性差,爆炸性能不稳定的难题,研究采用硝酸铵与微晶蜡、十八伯胺醋酸盐、稀释剂和水在115～125℃的温度下混溶,并在-0.07～-0.09 MPa下得到一种低爆速膨化铵油爆炸焊接炸药。对该炸药的热安全性、微观结构和机械感度进行了分析,研究了不同布药厚度对炸药爆速的影响,并进行铝/钢板爆炸焊接实验。结果表明,该炸药混合均匀,机械感度低,爆速在1900～2400 m.s-1之间,超声波探伤检测复合率达99%,能满足金属板材爆炸焊接的要求。In order to solve the problems of poor homogeneity and unstable explosion property of low detonation velocity explosive used in explosive welding. Ammonium nitrate was mixed with microcrystalline, octadecylamine acetate, diluents, and water at 115 -125 ℃, and it was dehydrated at -0.07 - -0.09 MPa. The thermal safety, microstructure and mechanical sensitivity were analyzed, the effect of the explosive layout thickness on detonation velocity was also studied, and the explosive welding test on aluminum-steel plate was done. The results show that the component has a good the mixing uniformity, the mechanical sensitivity is low, the detonation velocity is 1900 - 2400 m · s-1, and the recombination rate of ultrasonic flaw detection is up to 99%, which can satisfy the requirement of explosive welding of metal plate.
