【摘要】 采用撞击感度和DSC-TG测试方法,研究了Al H3对Al H3/PEG/NG/BTTN、Al H3/GAP/NG/BTTN以及Al H3/PET/不同类型硝酸酯等混合体系撞击感度的影响。结果表明,Al H3的引入使上述混合体系的撞击感度显著升高;在Al H3/PET/不同类型硝酸酯混合体系中,硝酸酯的分解峰温与混合体系的撞击感度存在线性相关性;在Al H3/PEG/NG/BTTN和Al H3/GAP/NG/BTTN混合体系中,Al H3和硝酸酯的分解峰温明显提前,活化能Ea显著降低。相对于Al H3/PEG/NG/BTTN体系,Al H3/GAP/NG/BTTN体系的撞击感度更高,这与GAP可加剧Al H3与硝酸酯的相互作用有关。
【Abstract】 The effect of AlH3 on impact sensitivity of AlH3/PEG/NG/BTTN, AlH3/GAP/ NG/BTTN and AlH3/PET/ different types of nitrate mixing systems text method were studies by impact sensitivity and TG-DSC. The results show that the mixed system of impact sensitivity was significantly increased in AlH3/PET/ different types of nitrate systems after adding AlH3. The decomposition peak temperature of nitrate ester is a linear relationship with the impact sensitivity of the AlH3/PET/ different types of nitrate systems. In the AlH3/PEG/NG/BTTN and AlH3/GAP/NG/BTTN mixed systems, the decomposition peak temperature of AlH3 and nitrate significantly are much lower and the activation energy of Ea decrease significantly compared with PEG/NG/BTTN and GAP/NG/BTTN systems respectively. The impact sensitivity of AlH3/GAP/NG/BTTN system is much higher than that of AlH3/PEG/NG/BTTN systems. The possible reaction was that GAP may be augmented the interaction between AlH3 and NE.
