摘　　要：利用热重法(Thermo Gravimetry,TG)和差示扫描量热法(Differential Scanning Calorimetry,DSC)研究了GHQ推进剂的热分解行为,采用Kissinger和Ozawa法分别求出其活化能,并计算了热爆炸临界温度和自加速分解温度。通过热履历实验研究了少部分GHQ推进剂样品分解对其整体热分解行为的影响,结果表明:GHQ推进剂热分解分为2个阶段,分别对应双基组分分解和RDX分解;少部分GHQ推进剂样品分解对双基组分分解有明显影响,对RDX分解基本无影响,热履历使GHQ推进剂热稳定性和热安全性降低。The thermal decomposition behavior of GHQ propellant is studied by ThermoGravimetry （TG） and Differential Scanning Calorimetry （DSC）, the activation energy is calculated with the Kissinger method and the Ozawa method respectively, and the critical temperature of thermal explosion and the self- accelerating decomposition temperature are calculated. The effect of partial decomposition of sample on the overall thermal decomposition behavior of GHQ propellant is studied by thermo-resume experiment. The result shows that the thermal decomposition of GHQ propellant is divided into double-base component decomposition and RDX decomposition; the partial decomposition of the sample has obvious effect on the double-base component decomposition, but has little effect on the RDX decomposition, thermo-resume reduces thermal stability and safety of GI-IQ propellant.
