The invention discloses a method for preparing an aqueous graphene/epoxy resin nanocomposite material. The method comprises the following specific steps: carrying out functional modification and dispersion on graphene oxide obtained through a Hummers method, so as to obtain a high-concentration aqueous graphene dispersion solution; adding epoxy resin into the aqueous graphene dispersion solution, uniformly stirring, then, dewatering under the vacuum condition, adding a curing agent and mixing; carrying out high-temperature curing, thereby obtaining the graphene/epoxy resin nanocomposite material. According to the method, the operating process is simple, convenient and controllable, so that large-batch preparation and synthesis are facilitated; through obtaining the highly-stable aqueous graphene dispersion solution, graphene and epoxy resin can have excellent interface compatibility and adhesion; the matrix adhesion, corrosion resistance and impact resistance of epoxy resin are effectively improved; compared with the conventional aqueous epoxy resin materials, the aqueous graphene/epoxy resin nanocomposite material prepared by the method has the advantages that the hardness is improved by 1.5 times, and the impact resistance is improved by 12 times.
