Abstract: | 4,4'- Diamino - diphenyl - sulfone (DDS) was chosen as curing agent. The curing reaction kinetic of eoxy resin of the diglycidyl ether of bisphenol A (E - 51 )/organic montmorillonite (MMT) system ( E -51/DDS) was studied by non -isothermal DSC and carefully analyzed. Based on the Kissinger method, the apparent activation energy (AE) was 59.91kJ/mol. The reaction order ( n =0.89) was calculated according to Crane theory, which indicates this curing reaction is a complex reaction. Based on this, the technology of curing reaction was determined. |
