摘要

合成了一种新型环氧树脂固化剂1

4-二(4-氨基苯-1-氧)正丁烷(DDBE)

并采用FTIR、1H NMR手段对其结构进行表征和确认。采用非等温差示扫描量热法(DSC)研究了N

N'-四缩水甘油基-4

4'-二氨基二苯甲烷(TGDDM)/DDBE体系的固化反应动力学

根据Kissinger方程计算体系的活化能为58.5 kJ·mol-1;采用Málek法进行模型拟合动力学分析

结果表明:其中的Šesták-Berggren模型的拟合曲线与实验的DSC曲线吻合

确定了体系的固化反应动力学参数和方程。DSC测试TGDDM/DDBE固化物玻璃化转变温度为195℃。

Abstract

A novel curing agent 1

4-bis(4-diaminobenzene-1-oxygen) n-butane(DDBE)was synthesized and its molecular structure was characterized by FTIR

1H NMR and DSC.It was used to cure N

N'-tetraglycidyl-4

4'-diaminodiphenyl methane(TGDDM).The non-isothermal reaction kinetics of TGDDM/DDBE system was investigated by dynamic DSC according to the model-fitting Málek method.The results showed that the apparent activation energy of the curing reaction was 58.5 kJ·mol-1 according to the Kissinger method

and the Šesták-Berggren model could satisfactorily describe the non-isothermal reaction of this epoxy resin system.The glass transition temperature of the cured TGDDM/DDBE was 195℃ according to DSC.
