Abstract:
The present disclosure relates to a preparation method for a two-component epoxy resin adhesive and the two-component epoxy resin adhesive prepared thereby. The preparation method comprises the following steps: mixing an epoxy compound and/or epoxy resin that contains more than two epoxy groups with an excess polyamine compound to prepare a prepolymer containing a terminal amino group; mixing the epoxy compound and/or epoxy resin that contains more than two epoxy groups with the prepolymer containing a terminal amino group, and then adding an alcohol substance to prepare component A; mixing an excess epoxy compound and/or epoxy resin that contains more than two epoxy groups with a polyamine compound to prepare a prepolymer containing a terminal epoxy group; mixing the polyamine compound with the prepolymer containing a terminal epoxy group to prepare component B; and mixing the component A and the component B to prepare the two-component epoxy resin adhesive.
