NOVELTY - Glycidyl ether epoxy resin and double-ended amino small molecular amine are reacted at 60-65 degrees C for 3-4 hours, to obtain terminal-amino hydrophilic polyether segment. The terminal-amino hydrophilic polyether segment and macromolecular resin are epoxy reacted at 60-65 degrees C for 3-4 hours, to obtain nonionic self-emulsifying epoxy curing agent. The nonionic self-curing epoxy curing agent is reacted with low-oxidation-degree graphene and reacted at 60-65 degrees C for 3-4 hours, to obtain graphene-aqueous epoxy high dispersion system. USE - Synthesis of graphene-based aqueous epoxy high-dispersion system used for preparing ultra-high-strength concrete and aqueous epoxy anticorrosive paint (all claimed). ADVANTAGE - The method enables synthesis of graphene-based aqueous epoxy high-dispersion system with high conductivity and modulus, and excellent mechanical property. DETAILED DESCRIPTION - Glycidyl ether epoxy resin and double-ended amino small molecular amine in molar ratio of 1:(2-2.1) are reacted at 60-65 degrees C for 3-4 hours, to obtain terminal-amino hydrophilic polyether segment. The terminal-amino hydrophilic polyether segment and macromolecular resin in molar ratio of (2-2.1):1 are epoxy reacted at 60-65 degrees C for 3-4 hours, to obtain nonionic self-emulsifying epoxy curing agent. Low-oxidation degree graphene is prepared by ultrasound-assisted Hummers method. The nonionic self-curing epoxy curing agent is reacted with low-oxidation-degree graphene in molar ratio of (2-2.1):1 and reacted at 60-65 degrees C for 3-4 hours, to obtain graphene-aqueous epoxy high dispersion system.
