摘　　要：制备了一种用于爆轰合成纳米MnFe2O4颗粒的新型乳化炸药,并对其制备工艺及爆轰特性进行探讨,确定了其制备工艺参数。通过爆速测量实验及爆轰产物检测,获得了该炸药的爆速,并研究了其爆轰状态。结果表明,该乳化炸药的制备工艺比传统炸药要求更加严格。纯净乳化基质不具备爆轰感度,添加RDX后,其爆轰参数与传统乳化炸药相近（或略低于）,并且具有较大的临界爆轰直径（〉32mm）。对爆轰产物分析可以判定炸药的爆轰反应状态,添加硝酸铵有利于促进爆轰反应结构均匀性。A new type of emulsion explosive used to prepare nano-MnFe2O4 powders via detonation method was prepared,the parameters of the preparation process,detonation velocities and characteristics of the explosives were discussed,tested and researched respectively.Results indicated that the preparing process of the emulsion explosives was more rigid than that of traditional emulsion explosives.However,pure emulsion base could not be detonated by detonator except of adding some RDX as sensitizer.Detonation velocity test indicated that the emulsion explosives had relatively lager critical detonation diameter（32mm） and could be stably detonated with the velocities closed to those of traditional explosives.The detonation state of the emulsion explosives could be judged and evaluated by detonation products,and the structural uniformity of detonation reaction could be improved by adding ammonium nitrate in the oxidants of the explosives.
