NOVELTY - Low-density anticorrosive paint comprises component A including 40-60 pts. wt. epoxy resin, 5-15 pts. wt. graphene paste, 10-20 pts. wt. pigment, 5-10 pts. wt. filler, 0.5-1.5 pts. wt. leveling agent, 0.5-1 pts. wt. dispersant and 10-20 pts. wt. diluent; and component B including polyamide-based curing agent, where the polyamide curing agent is Versamid 115, Versamid 125 and/or Versamid 140; and the weight ratio between component A and component B is 100:30-60. USE - The low-density anticorrosive paint is useful for graphene-based aluminum alloys (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing low-density anticorrosive paint comprising ( i) adding polyurethane dispersant 7163 into the solvent, stirring, adding graphene powder, stirring and dispersing at 22-28 degrees C to obtain graphene slurry, and (ii) mixing the epoxy resin with the diluent evenly to obtain mixture, and then adding graphene slurry, pigment, filler, leveling agent and dispersant, stirring, grinding, filtering, and packaging to obtain final product.
