LI Jingrui, LIU Jialin, ZHANG Junying, et al. Non-isothermal curing reaction kinetics of TGDDM/1,4-bis(4-diaminobenzene-1-oxygen) n-butane[J]. CIESC Journal, 2013, (9): 3421-3427.
4-bis(4-diaminobenzene-1-oxygen) n-butane(DDBE)was synthesized and its molecular structure was characterized by FTIR
1H NMR and DSC.It was used to cure N
N
N'
N'-tetraglycidyl-4
4'-diaminodiphenyl methane(TGDDM).The non-isothermal reaction kinetics of TGDDM/DDBE system was investigated by dynamic DSC according to the model-fitting Málek method.The results showed that the apparent activation energy of the curing reaction was 58.5 kJ·mol-1 according to the Kissinger method
and the Šesták-Berggren model could satisfactorily describe the non-isothermal reaction of this epoxy resin system.The glass transition temperature of the cured TGDDM/DDBE was 195℃ according to DSC.
