Abstract

A triethylenetetramine epoxy mixture was synthesized through the reaction of a low-molecular-weight liquid epoxy resin with triethylenetetramine (TETA). Then triethyltetramine (TETA) was injected dropwise into a propylene glycol methyl ether (PM) solution for chain extension reaction. A hydrophilic and flexible polyether segment was introduced into the hardener molecule. The effects of TETA/DGEPG, reaction temperature and reaction time on the epoxy conversion of polyethylene glycol diglycidyl ether (DGEPG) were studied. In addition, several alternate strategies to add epoxy resin to the high-speed dispersion machine and synthesize MEA DGEBA adduct (without catalyst and with bisphenol A diglycidyl ether epoxy resin) were compared. It was found that the higher the molecular weight of triethylenetetramine, the longer the chain segment of the surface active molecule. When the equivalence ratio of amine hydrogen and epoxy group is low, the stability of lotion is good. When the ratio of amine hydrogen to epoxy group is large, the content of triethylenetetramine is small. The main objective of this study is the provision of new data and knowledge for the development of new materials in the coating and electronic industry.
