摘要/Abstract

摘要： 采用非等温差示扫描量热法(DSC)对环氧树脂FM94胶黏剂的固化动力学进行了研究。基于Model-Free法,分析了不同升温速率下的DSC曲线,解释了FM94胶黏剂的固化机理,求解了反应活化能E值,并通过Malek法确定了固化机理函数为自催化模型。结果表明,采用Model-Free法与Malek法结合获得的自催化模型与实验数据吻合得较好,求解得到的模型在升温速率为2 K/min~10 K/min下能较为准确地描述环氧树脂FM94胶黏剂的固化反应过程。

Abstract: The curing kinetics of epoxy resin FM94 adhesive was studied by differential scanning calorimetry (DSC) at different heating rates. The activation energies of the curing reaction were calculated based on Model-Free method by analyzing DSC curves at different heating rates, and the curing mechanism of FM94 adhesive was explained. The most probable curing mechanism function was determined by Malek method. The results indicated that the two-parameter (m, n) autocatalytic model can well describe the curing reaction process of FM94 adhesive. The fractional conversion of DSC curves obtained using the experimental data showed a good agreement with the curves calculated theoretically under 2 K/min~10 K/min heating rates.

Key words: dynamic DSC, FM94 adhesive, curing mechanism, Model-Free method, Malek method
