摘　　要：建立了一种利用热重峰值分析进行酚醛树酯热解动力学研究的方法,这种方法利用热重谱峰上几个特征点的数据来确定动力学参数.根据酚醛树酯热解DTG曲线的特点,把酚醛树酯的热解过程分解成三个阶段,用峰值分析法对每个反应阶段分别建模,通过三个反应阶段的叠加得到了一个酚醛树酯分阶段热解动力学模型,该模型能够很好地描述酚醛树酯的热解过程.A method used for the study of thermal decomposition kinetics by peak analysis was developed. This method needs only a few eigenvalues of the thermogravimetric mass loss curves for the determination of kinetic parameters. A peak separation was performed to separate the thermal decomposition of phenolic resin into three stages according to the characteristic of the experimental differential mass loss curve. Kinetic parameters for each stage were determined using peak analysis method. A decomposition kinetic model, which was shown to accurately describe the decomposition process of phenolic resin, was obtained by the combination of these three stages.
