新型起爆药5-硝基四唑亚铜工艺优化及性能研究

Synthesis Process and Property of New Primary Explosive Copper(Ⅰ) Nitrotetrazolate

以氯化亚铜、5-硝基四唑钠等为原料合成了一种新型绿色环保起爆药5-硝基四唑亚铜(CuNT),对其合成工艺进行了研究,通过单因素实验分析得到合成的较佳工艺条件。对CuNT的物理性能、热性能和爆炸性能研究结果表明,CuNT具有较好的流散性,吸湿性和耐热性均较好,机械感度、火焰感度及静电感度较钝感,摩擦感度相对较高;CuNT的爆热与比容值均大于叠氮化铅和斯蒂芬酸铅等常规起爆药;CuNT对结晶RDX的极限起爆药量为20mg。

A new green primary explosive copper（Ⅰ） nitrotetrazolate（CuNT） was synthesized from cuprous chloride,sodium 5-nitrotetrazolate,etc.The synthesis process was studied through single factor experiment.The results show that CuNT is of good free-running property,hygroscopicity and thermal stability.The compound is insensitive to impact,flame and static discharge.Also,the minimum quantity experiment shows that the CuNT has a fairly high explosion capacity that only 20 mg could detonate the RDX.In some initiating devices,CuNT may be a substitute for Pb（N3）2 and lead styphnate.
