摘要
斯蒂芬酸铅是我国目前广泛使用的单质起爆药之一,由于它具有较高的火焰感度和点火能力,与叠氮化铅一起成为多种型号雷管的主装起爆药。但是,斯蒂芬酸铅的静电感度很高,在生产、贮存、使用过程中均易出现意外事故。因此,极有必要研究降低斯蒂芬酸铅静电危害的方法和措施。化学合成法制得了表面包覆有碳纳米管(CNTs)的斯蒂芬酸铅晶体,研究了不同碳纳米管含量对斯蒂芬酸铅静电性能的影响结果,设置CNTs含量为1%~6%进行了六个对照组实验验证,系统研究了在斯蒂芬酸铅(LTNR)晶体表面掺杂碳纳米管(CNTs)后的主要静电性能变化情况。试验结果表明,在试验范围内,碳纳米管含量越多,LTNR的静电积累降低越多;而静电火花感度仅在CNTs含量为1%、2%时有明显降低,随着碳含量继续增高,药剂本体导电性增加、易导电在间隙间产生放电、导致静电火花感度相应增加,与未包覆的LTNR基本相同。通过在斯蒂芬酸铅晶体表面加入一定量的碳纳米管,在一定程度上可以提高斯蒂芬酸铅的抗静电安全性。
Lead Styphnate(LTNR)is one of the most widely-used primary explosives in many type detonators together with lead azide(LA),due to their proper sensitivities.Otherwise,LTNR is very sensitive to static electric spark,of which often causes dangerous accidents.This paper mainly focuses on how to improve the anti-static-electric property of LTNR and modified with carbon nano-tubes(CNTs)in our research.LTNR crystal modified with CNTs was prepared in our research.We studied their electric spark sensitivity and electrostatic accumulation separately with setting six groups of different CNTs-containing by 1%~6%.Our experiments show that more CNTs contained,less static electricity would be accumulate.But situation changes in electrostatic spark sensitivity.When CNTs containing is less than 2%,the electric spark sensitivity is decreased obviously.When CNTs content is more than 2%,electric spark sensitivity of the powder stays nearly unchanged.Carbon nano-tubes can reduce the electric spark sensitivity of LTNR,improving its safety.But there can’t be too many carbon nano-tubes..
