| 摘 要： | 本文利用差示扫描量热法（DSC）研究了不同升温速率下环氧树脂E-20/甲醇醚化氨基树脂（MEAR）体系固化反应动力学;采用Kissinger、Ozawa法计算得出体系固化表观活化能分别为35.67kJ/mol、40.27kJ/mol;用Crane公式求出反应级数为0.95,表观频率因子为1.12×10^4s^-1。根据固化反应产物红外光谱分析了反应机理,在200℃以下,烷氧基甲基（=NCH2OCH3）与环氧基团反应是主反应,烷氧基甲基基本不与羟基（-OH）反应。

| Abstract: | In this paper, differential scanning calorimetry （DSC） was used to study the curing reaction kinetic of the diglycidyl ether of bisphenol A （DGEBA） with a methanol etherified amino resin （MEAR）. The apparent activation energy derived from Kissinger and Ozawa methods is 35.67kJ/mol and 40.27kJ/mol, respectively. The reaction order evaluated by Crane equation is 0. 95 and the apparent frequency factor is 1.12×10^4s^-1. Reaction mechanism was monitored by FFIR spectra of the reaction mixtures before and after curing. The curing reaction below 200℃ is between alkoxylmethyl （ = NCH2 OCH3 ） and epoxide group, not between alkoxylmethyl and hydroxyls. |
