叠氮硝胺对硝基胍发射药热行为的影响
Influence of Azidonitramine on the Thermal Behavior of the Nitroguanidine-base Gun Propellant
摘要
Abstract
A new gun propellant was prepared via replacing the nitroglycerin (NG)with mass fraction of 6% in the nitroguanidine (NQ)-based gun propellant by 1,5-diazido-3-nitrazapentane (DIANP).The effect of DIANP on the thermal behavior of NQ-based gun propellant was studied by high-pressure differential scanning calorimetry,explo-sion temperature test,methyl violet test,vacuum stability test,and thermal accelerated aging test.The apparent activation energy (Ea )of the decomposition reaction of gun propellant sample was calculated by Kissinger equation and Ozawa equation.The results show that a small amount of DIANP makes the thermal stability of NQ-based gun propellant improve slightly.The Ea values obtained by Kissinger equation and Ozawa equation are 327 and 318 kJ/mol respectively for NQ-based gun propellant with DIANP,196 and 194 kJ/mol respectively for NQ-based gun propel-lant.The Ea value of NQ-based gun propellant with DIANP is much less than that of NQ-based gun propellant.Their iso-kinetic temperature Tik is 172.9℃,showing that the addition of DIANP decreases the decomposition rate of NQ-based gun propellant at high temperature,the addition of DIANP can adjust the burning rate of NQ-based gun propellant to a certain degree.The safe storage life of NQ-based gun propellant with DIANP and NQ-based gun propellant at 30℃ predicted by temperature-factor-method is not less than 31 years and 23 years respectively,revealing that adding a small amount of DIANP can prolong the safe storage life of NQ-based gun propellant.关键词
