摘　　要：为探究六亚甲基四胺含量对铵胺炸药性能的影响,采用质量分数为5.5%、6.5%、7.5%、8.5%、9.5%的六亚甲基四胺制备5组铵胺炸药。通过黏度分析仪、计时仪、爆速测试仪和热分析技术,对铵胺炸药的交联时间、爆速以及热分解过程进行研究。实验结果表明,当六亚甲基四胺的质量分数从5.5%增加至9.5%时:铵胺炸药的交联速度逐渐放缓,交联时间由7 h延长至13 h;爆速由3552 m/s上升至4070 m/s,而后下降至3663 m/s;六亚甲基四胺含量对铵胺炸药的热分解过程没有明显影响,铵胺炸药的表观活化能由93.71 kJ/mol上升至124.71 kJ/mol,热安定性得到提升。To investigate the effect of hexamethylenetetramine content on the performance of ammoniumamine explosives,five groups of ammonium-amine explosives were prepared using hexamethylenetetramine with mass fractions of 5.5%,6.5%,7.5%,8.5%and 9.5%.The cross-linking time,detonation velocity and thermal decomposition process of ammonium-amine explosives were studied by means of viscosity analyzer,chronograph,detonation velocity tester and thermal analysis techniques.The results show that when the mass fraction of hexamethylenetetramine increases from 5.5%to 9.5%,the cross-linking speed of ammoniumamine explosive gradually slows down and the cross-linking time gradually increases from 7 h to 13 h,and the detonation velocity of explosive increases firstly from 3552 m/s to 4070 m/s and then decreases to 3663 m/s.The content of hexamethylenetetramine has insignificant effect on the thermal decomposition process of ammonium-amine explosives.With increasing content of hexamethylenetetramine,the apparent activation energy of ammonium-amine explosive increases from 93.71 kJ/mol to 124.71 kJ/mol,and the thermal stability is improved.
