Abstract:Based on long-standing fundamental research in our laboratory,the related somescientific problemshidden in industrial application of epoxy resin could beabstracted and solved.The important matter for epoxy resin is difficult to balance the long-term stability during shelf lifeand fast curing speed during application because the same curing reaction always take placein thesystem even in room temperature during storage.Aseries of bifunctional epoxy resin wasdesigned and synthesized,and the related dual curing mechanism was revealed including"Synergistic" curing reaction for Diallyl-bearing epoxy resin(Diglycidal Ether of 4,4-diallylbisphenol A,DGEDABA) and sulfur donors system,Ring-open reaction and Diels-Alder(D-A)reaction for furan-group containing bisphenol epoxy resin iglycidal Ether ofbis(4-hydroxy-3,5-di-methylphenyl)-furylmethane,DGEDMF)and malefic anhydride system,andring-open reaction andhumidity-curing reaction for siliconized epoxy resin (SEP).
