摘要:
研究了丙烯腈丁二烯苯乙烯共聚物热分析动力学参数.采用热重差热分析法,分别测定了在氮气气氛中5、10、15、20 ℃/min 4种不同升温速率下的的热降解过程,得到了4条热重和差热曲线,并用Kissinger法对其热降解过程进行了动力学分析.结果表明:提高升温速率,热重曲线向高温方向移动,温度滞后越严重.初始分解温度及终止分解温度更高,温度区间也变宽.升温速率的不同对最终失重率影响不大,最终失重率都在90%以上.随着升温速率的增加,差热曲线峰变高且峰顶温度向高温方向移动.通过Kissinger法分析在不同升温速率下丙烯腈丁二烯苯乙烯共聚物热降解反应的热重差热数据得出反应的活化能为1609 kJ/mol、表观指前因子为27.61、热降解反应级数为0.965 4等动力学参数.
Abstract:
To study kinetic parameter of thermal analysis with acrylonitrilebutadienestyrene copolymer, thermal degradation process of acrylonitrilebutadienestyrene copolymer was measured by hermogravimetric and differential thermal analysis method at different heating rates of 5, 10, 15 and 20 ℃/min in N2. Four hermogravimetric and differential thermal analysis curves were investigated by Kissinger method kinetic analysis. With increase of the heating rate, thermogravimetric curve moves to high temperature, temperature hysteresis becomes more serious. Moreover, the initial decomposition temperature and the decomposition temperature of termination become higher, and the temperature interval becomes wider. The rates of final weight loss are not influenced by different heating rates and they all are over 90%. The peak of differential thermal analysis curve becomes higher and peak temperature gets higher when the heating rate increases. The apparent activation energy of acrylonitrilebutadienestyrene copolymer thermal degradation at different heating rates is 160.9 kJ/mol, preexponential factor is 27.61, and the reaction order is 0.965 4 by Kissinger method kinetic analysis.
