Study on Curing Kinetics of Fatty Amine/Epoxy Resin Using Non-Isothermal DSC Method

The curing processing of fatty amine/epoxy resin was studied by non-isothermal differential scanning calorimetry (DSC) at different heating rates. The curing kinetics mechanism function and the kinetic parameters were determined using n order reaction and autocatalytic reaction and the model-free method. The curing processing was determined by extrapolation method. The results indicated that n order reaction model does not accord with the basic reaction characteristics of curing system. While the DSC curves from the autocatalytic model can well agree with that of experiment. The whole curing reaction process accords with the autocatalytic reaction model. The results by using FWO and FR method can also confirm that the curing reaction of resin system belongs to the autocatalytic model.
