| 摘 要： | 采用Málek法对桐马酸酐与双酚A环氧树脂E-51体系(含有1%质量分数的DMP-30)的非等温固化反应动力学进行了研究。通过机理函数esták-Berggren方程很好地模拟了真实的固化反应过程。等转化率法求得反应活化能为69.78 kJ/mol。指前因子A的值为4.567×108 min-1,n和m的值分别为1.082和0.456。根据得到的固化动力学方程计算可知,在固化温度为137.05℃时达到98%固化度的固化时间为115 min。

| Abstract: | The non-isothermal curing kinetics of Tung-maleic anhydride and epoxy resin E-51 blend with 1% DMP-30 by weight was studied by Málek method.The real curing process was stimulated well using mechanism equation esták-Berggren.The active energy calculated by iso-conversion ratio method was 69.78 kJ/mol.The pre-exponential factor A was 4.567×108 min-1 and the values of n and m were 1.082 and 0.456,respectively.Based on the curing kinetic equation obtained,the calculated curing time of the system with 98% conversion rate was 115 minutes at the curing temperature 137.05 ℃. |
