利用含废弃丁羟推进剂制备的高能炸药❋

     

摘要

A new type of high explosive was successfully prepared by filling up the obsolete HTPB particle gaps with energetic binder containing a sensitizer formulated by acrylamide oxidizing agent solution and aluminum powder. Detonation performance, overpressure and energy output characteristics were studied by high speed photography, aerial and underwater explosion tests. The results demonstrate the high performance of this new high explosive. The detonation sensitivity, over-pressure and underwater power output improve significantly with increased content of sensitizer. For the explosive with densityof up to 1. 53 g/cm3 and detonation velocity of up to 6 900 m/s, its equivalent TNT coefficient is slightly about 1 at distance ratio from 1. 5 m/kg1/3 to 4. 5 m/kg1/3 , and energy output from underwater explosion was observed as 4. 5 kJ/g which is higher than that of TNT. The explosion of this high explosive has high energy and shock effect.%利用丙烯酰胺氧化剂溶液及铝粉制备得到敏化剂,加入已配好的含能黏结剂中,对丁羟( HTPB)推进剂颗粒间隙进行填补,形成新型高能炸药。通过高速摄影试验观察爆轰过程,炸药空中、水下爆炸等试验测试其性能。结果表明:所制备的新型高能炸药性能良好,随着敏化剂含量的增加,炸药爆轰感度、冲击波超压及水下能量输出均有明显提高;炸药密度1.53 g/cm3,爆速6900 m/s;当比例距离为1.5~4.5 m/kg1/3时,炸药的TNT当量系数分布于1左右;水下爆炸能量输出为4.5 kJ/g,高于TNT,具有较高的能量和冲击作用。
