中文摘要:
      采用自行设计的一种烤燃实验装置,对一种新型熔铸载体炸药2,4-二硝基苯甲醚(DNAN)的热安全性进行了实验研究,得到其自发火温度、热爆炸延滞期和热爆炸临界温度,并与传统熔铸载体炸药TNT进行了对比。实验结果表明,DNAN的自发火温度为346.7 ℃、5 s爆发点为374.1 ℃、活化能为48.37 kJ·mol -1。DNAN在220 ℃的环境温度下,放置48 h没有发生反应; 230 ℃时,药剂发生不完全燃烧; 当温度达到240 ℃以上时DNAN发生热分解反应; 理论计算DNAN在通常的熔铸温度(100 ℃)下的热爆炸延滞期,表明了在该温度下熔铸是安全的。

英文摘要:
      The thermal safety of 2,4-dinitroanisole(DNAN) explosive was studied by cook-off test. The self-ignition temperature,the delay time of thermal explosion and the critical temperature for the thermal explosion of DNAN were obtained,and the test results were compared with that of TNT. The results show that the self-ignition temperature of DNAN is 346.7 ℃,the temperature of 5 s explosion point is 374.1 ℃, and activation energy is 48.37 kJ·mol-1. Under the ambient temperature of 220 ℃,when DNAN is placed for 48 h, DNAN is nonflammable. DNAN is semi-burned under the ambient temperature of 230 ℃. When the temperature reaches above 240 ℃, thermal decomposition reaction of DNAN occurs. The delay time of thermal explosion was obtained from theoretical calculation at 100 ℃. Results show that DNAN is stable and safe in the melting process of temperature below 100 ℃.
