摘要
为寻求可替代TNT用于熔铸炸药的液相载体,研究绘制了1,3,3-三硝基氮杂环丁烷(TNAZ)与3,4-二硝基呋咱基氧化呋咱(DNTF)混合物的二元相图,并表征了最低共熔物的热安定性、感度、能量性能、渗油性等。结果表明:当TNAZ与DNTF质量比为60/40时为最低共熔物,其共熔点为79.0℃;最低共熔物热分解温度高、热安定性好,机械感度适中,静电火花感度优于B炸药;70℃恒温放置6h不渗油,是一种具有潜力的可替代TNT的熔铸炸药。
A phase diagram of 1,3,3-trinitroazetidine(TNAZ) and 3,4-dinitrofurazanofuroxan(DNTF) was drawn by Origin software. The thermal stability, sensitivity, energetic performance and the exudation of the eutectic mixture were characterized, in order to design a potential TNT replacement for melt-cast explosive. The results showed that when the weight percent of TNAZ was 60%, the mixture had the lowest melting point of 79.0℃. The eutectic mixture had good thermal stability, moderate mechanical sensitivity, its electrostatics sensitivity were superior to Comp.B. Furthermore, another advantage of eutectic mixture was that there was no exudates at 70℃ for 6h. The results indicated that the eutectic mixture was a potential replacement of TNT for melt-cast explosive.
