DETAILED DESCRIPTION - High conductivity and heavy anti-corrosive paint comprises A and B components, where component A comprises 80-90 pts. wt. organosilicon modified epoxy resin, 10-100 pts. wt. graphene/epoxy resin master batch, 5-50 pts. wt. glass flake micro-chip, 100-200 pts. wt. diluent and 0.1-5 pts. wt. additive. The component B comprises 20-60 pts. wt. curing agent. The graphene is used in the form of graphene nano-sheets so as to form the graphene/epoxy resin masterbatch and glass flakes micro powder of component A is added to graphene/epoxy resin master batch to replace graphene nano-sheet powder. The graphene nano-sheets have maximum degree of flexibility and are rigid. The film-forming process is carried out to obtain ordered stacked structure in which graphene nano-sheets are uniformly distribution in the coating. The ordered structure is conductive and improves the barrier properties of the coating. INDEPENDENT CLAIMS are included for a method for high conductivity and heavy anti-corrosive paint preparation, which involves (1) mixing and stirring epoxy resin, organosilicon resin and graphene/epoxy resin master batch at low speed stirrer for 20-40 minutes, where the rotating speed is 300-500 rotations/minute; adding glass flake microchip, diluent and additive, stirring at high speed of 1200-1500 rotations/minute for 1-3 hours; mixing each raw material of components A, B uniformly according to ratio split charging can be obtained and can be used; and (2) a method for graphene/epoxy resin master batch preparation involves soaking dry nano carbon powder in alcohol solvent, ultrasonically treating and high speed stirring or cutting dispersing treatment using nano carbon-alcohol suspension; mixing nano carbon-alcohol suspension with liquid resin, stirring to alcohol solution until delamination of resin occurs, the upper layer is milk or gray white low viscosity alcohol solution, the lower layer is black high viscosity material; separating upper layer and lower layer from alcohol solution, collecting the lower layer material by heating and vacuum pump drying; dispersing uniformly with nano carbon and composite resin slurry; collecting the upper layer from the alcohol solution using distillation method of purifying after repetitive use; mixing 1000 gram intercalated peeled graphene nano-sheet powder to 30 kilograms of hexanol, ultrasonically dispersing for 30 minutes to obtain transient dispersion of graphene/alcohol suspension; mixing graphene/alcohol suspension and 10 kilograms epoxy resin in a stirrer, stirring at the speed of 200 rotations/minute for 5 hours; keeping the mixture in a static place for 10 minutes; separating using the mixed liquid delamination, separating gray-white upper layer from the solution, leaving the black thick paste lower layer in vacuum drying tank; vacuumizing and heating at 120 degrees C, keeping in drying tank, vacuum degree is lower than 100 pascal, drying for 24 hours; and taking out to obtain 10 wt.% graphene nano-sheets of graphene/epoxy composite masterbatch.
