【 摘 要 】

A novel and convenient method for the synthesis of epoxy resin curing agent ethylenediaminetetraacetic anhydride (EDTAD) was explored. The curing reaction kinetics of DGEBA/EDTAD/DMP-30 system was studied by non-isothermal differential scanning calorimetry (DSC). The experimental results show that there are two exothermic peaks in the non-isothermal curing reaction curve; the higher the heating rate, the higher the peak temperature, the shorter the curing reaction time; the table of DGEBA/EDTAD/DMP-30 system is obtained by Kissinger and Ozawa methods The apparent activation energies of the DGEBA/EDTAD system were 4.9kJ/mol, 67.8kJ/mol and 7.3kJ/mol, 72.1kJ/mol respectively. The apparent activation energies of 36.1kJ/mol, 44.5kJ/mol and 41.2kJ/mol, 48.9kJ/mol.
