【摘要】 利用TG-DTG、DSC技术详细研究了3,5-（硝氨基）-1,2,4-三唑肼盐（HDNAT）的热分解过程、分解反应动力学及其与HMX、RDX、NC、NG、吸收药（NC+NG）、DINA、DNTF和铝粉等含能材料的相互作用和相容性。研究结果表明,在160²30℃温度范围内,HDNAT的分解过程存在一主一次两个放热分解过程,在DSC曲线上表现为一个明显的放热峰和一个3肩缝;HDNAT的热分解符合"成核增长"历程,分解反应机理函数为dα/dt=10^19.8（1-α）[-ln（1-α）]^3/5 e^-22.2/T.,其分解反应活化能Ea=184.8kJ·mol^-1,指前因子A=1019.4s^-1;HDNAT与DINA和NDTF之间存在明显的相互作用,与之不相容;与RDX之间有微弱的相互作用,相容性较差;与HMX、NC、NG、（NC+NG）和Al之间不存在相互作用,相容性良好。更多还原

【Abstract】 The decomposition processes,decomposition reaction kinetics of hydrazinium 3,5-dinitramino-1,2,4-triazolate（ HDNAT）,and the interactions and compatibility of HDNAT with some energetic materials were investigated by thermogravimetry and differential thermogravimetry（ TG-DTG）,and differential scanning calorimetry（ DSC） under atmospheric pressure and flowing nitrogen gas conditions. The energetic materials, cyclotetramethylenetetranitroamine（ HMX）, cyclotrimethylenetrinitramine（ RDX）,nitrocellulose（ NC）,nitroglycerine（ NG）,125/100-NC/NG mixture（ NC+NG）,N-nitrodihydroxyethylaminedinitrate（ DINA）,aluminum powder（ Al） and 3,4-bisnitrofurazanfuroxan（ DNTF）,were used. It was experimentally found that the thermal decomposition processes of HDNAT has a major stage（ main exothermic peak） and a minor stage（ shoulder exothermic peak）in the temperature range of 160 230 ℃,and the kinetic equation of HDNAT decomposition can be expressed as nucleation and3 growth process,dα/dt = 10^19.8（1-α） [-ln（ 1-α）]^3/5 e^-22.2/T,with Ea= 184.8kJ ·mol^-1 and A = 1019.4s^-1. There is obvious interaction between HDNAT and DINA or DNTF,slight interaction between HDNAT and RDX,while little interactions between HDNAT and HMX,NC,NG,（ NC+NG） or Al. The HDNAT-HMX,HDNAT-NC,HDNAT-NG,HDNAT-（ NC+NG） and HDNAT-Al binary mixtures have good compatibility,and the HDNAT-RDX binary mixture has fair compatibility,and the HDNAT-DINA and HDNAT-DNTF binary systems have poor compatibility,however.更多还原
