研究了N,N,N',N'-四缩水甘油基-4,4'-二氨基二苯甲烷(TGDDM)与含活性基团羟基的固化剂3,3'-二氨基-4,4'-二羟基联苯(DADHBP)的固化反应动力学.通过对固化体系的差示扫描量热法(DSC)的测试数据进行分析,利用OzaWa、Kissinger、Crane和Arrhenius方程对此进行了固化反应动力学研究.计算得到了固化体系的动力学参数:反应活化能Ea、反应级数n、频率因子A及峰温时的反应速率常数kpo结果表明,在TGDDM/DADHBP体系的固化反应过程中,DSC曲线出现了两个明显的放热峰,低温放热峰所对应的平均反应活化能(Ea1)为110.19 kJ/mol,反应级数(n1)为0.94;高温放热峰所对应的平均反应活化能(Ea2)为143.89 kJ/mol,反应级数(n2)为0.95.
