摘要
系统归纳了采用DSC法建立的热固性树脂固化反应动力学模型,包括模型拟合法及无模型法。模型拟合法的关键在于确定动力学三因子,即反应模型、频率因子和反应活化能。无模型法可避免因反应模型的选择不当而造成的动力学参数的偏差。最后探讨了模型拟合法和无模型法的使用局限。
Differential scanning calorimetry（DSC）, a powerful technology to analyze the characteristics of chemical reactions, is widely used to determine the kinetic parameters of thermoset cure reactions. Research achievements in kinetic modeling of thermosetting resins were reviewed, including model-fitting method and model-free method. Kinetic model, frequency factor and Arrhenius activation energy make up a ‘kinetic triplet＇, which is the key section in model-fitting method. The remarkable derivation of kinetic parameters, resulting from the misidentification of a suitable kinetic model, will be eliminated when Model-free method is adopted. Some limitations of the two methods were also discussed.
