Abstract:The curing reaction of multifunctional epoxy resin system was studied by using non-isothermal DSC(differential scanning calorimetry),methyl nadic anhydride(MNA) as curing agent was determined.And then the curing reactivity for a system of AG-70/MNA/2-ethyl-4-methylimidazole(EMI-2,4) was measured at different heating rates.According to the DSC curves,the curing parameters were obtained by using T-β curve extrapolation,the temperature parameters could supply a guidance to the proper curing process.The kinetic parameters of the curing reaction of AG-70 epoxy resin system were calculated by using Kissinger and Crane equation,the kinetic model based on the nth order reaction equation was set up.Finally the curves of degree of cure a vs.temperature and time,rate of reaction dα/dt vs.temperature and time were analyzed respectively,it shows that the calculated data is in good agreement with that theoretically.
Keywords:epoxy resin  cure reaction  DSC  kinetic model
