STUDY ON CURING REACTION OF EPOXY RESIN WITH p-TOLYBIGUANIDE

Abstract

Abstract: The nonisothermal and isothermal curing processes of epoxy resin with p-Tolybiguanide were investigated using isoconversional methods and model-fitting methods based on differential scanning calorimetry (DSC). The kinetic mechanism function and kinetic parameters of curing reaction are determined using the most probability mechanism function method developed by Malek. The result show that the values predicted by advanced autocatalytic model with consideration of diffusion-controlled mechanisms tended to match the isothermal curing experimental values. Moreover, curing procedures and mechanism of different temperature programs and different curing degree were discussed on the base of the activation energies varying with curing degree and the comparison of values calculated by autocatalytic models and experimental values. Furthermore, the kinetic research provides theoretical basis for the optimization of the curing process.

Key words: epoxy resin, DSC, curing reaction, reaction kinetics
