摘要:利用TG-DSC联用技术测试了汽油和柴油对乳化炸药基质热分解特性的影响，并用Ozawa法及Satava-sestak法对测试数据进行了分析，得到了乳化炸药基质及其与汽油、柴油混合物热分解反应的积分形式反应机理函数。结果表明：在5种不同升温速率下，相较于乳化基质，乳化炸药基质与汽油、柴油的混合物起始加速分解温度降低；乳化炸药基质及其与汽油、柴油混合物的活化能分别为94.42 kJ/mol、81.43 kJ/mol、78.50 kJ/mol。研究表明汽油、柴油等有机燃料在热作用下能加快乳化炸药的热反应速度，应避免接触和混合。
Abstract:By use of assembling TG and DSC technique, the gasoline and diesel oil influencing on the thermal decomposition characteristics of emulsified explosive matrix was measured, Ozawa and Satava-sestak method were applied in test data analysis, and thermal decomposition kinetics mechanism functions were obtained. The results show that under 5 different heating rates, the initial accelerated decomposition temperature of mixtures of emulsion explosive matrix with gasoline and diesel oil both decreased compared with that of emulsion matrix; Activation energy of emulsion explosive matrix and mixtures of emulsion explosive matrix with gasoline and diesel oil were 94.42 kJ/mol, 81.43 kJ/mol, 78.50 kJ/mol respectively. The study indicates that gasoline and diesel oil can accelerate the reaction rate of emulsion explosive under thermal action, so the contact and mixture should be avoided.
