| 摘 要： | 用差示扫描量热仪和RS600旋转流变仪分别研究了AG-70环氧树脂体系的升温固化反应情况和升温及恒温条件下的流变性能。实验结果表明,该环氧树脂体系的固化动力学方程符合两参数自催化模型,采用Malek最大概然法计算了模型中的动力学参数,获得了两个特征值下的动力学方程,将实验结果与理论值进行了对比。采用两种方式确定了凝胶温度点,并与用差示扫描量热(DSC)方法获取的凝胶点温度作比较,利用恒温温度与凝胶时间的函数关系计算出了凝胶模型,其数学表达式为:lntgel=-19.67+8.57/T。

| Abstract: | The curing reaction and rheological behavior of AG-70 epoxy resin system were measured using non-isothermal differential scanning calorimetry(DSC) and non-isothermal and isothermal RS600 Rotational Rheometer,respectively.From the experimental data,it is found that the cure kinetic equation of epoxy resin is correspond with two-parameter autocatalytic model.The kinetic parameters in model were calculated using the most probability method supported by Malek,and the kinetic equations were obtained from two cha... |
