摘要
采用DSC和TG试验研究了BNCP的热性能,并与常规起爆药Pb(N3)2和CP进行了对比。设计了一种热烤实验装置,对BNCP的耐热性进行了实验研究。结果表明,BNCP的热分解温度低于Pb(N3)2和CP,但其表观活化能大于Pb(N3)2和CP。BNCP在240℃以下的环境温度中的分解量较小,有较好的热安全性。在环境温度低于90℃的条件下,可以长期放置。当环境温度接近药剂的热分解温度266℃时,药剂被烤爆,烤爆温度为248～260℃。
The thermal safety of BNCP is studied with the experimental methods. The DSC and TG tests of BNCP were carried out. Compared with Pb(N3)2 and CP, the temperature of decompose of BNCP is lower and the Ea of BNCP is larger. A cookoff test system was designed and the cookoff tests were carried out to study the thermal safety of BNCP. The results show that the thermal safety of BNCP is good when the environmental temperature is below 240℃. It has a long storage time when the environmental temperature is below 90℃. BNCP was detonated when the environmental temperature is about 266℃. The cookoff temperature of BNCP is 248～260℃.
