NOVELTY - An anticorrosive coating comprises 100 pts. wt. boron phenolic resin modified tetrafunctional epoxy resin, 100-150 pts. wt. bisphenol S epoxy resin, 40-80 pts. wt. bisphenol A epoxy resin, 60-100 pts. wt. boron phenolic resin, 5-15 pts. wt. modified amino resin, 90-120 pts. wt. silane resin modified quartz powder, 80-100 pts. wt. filler, 20-40 pts. wt. film-forming aid, 160-250 pts. wt. solvent, 10-25 pts. wt. other additive, and 50-80 pts. wt. graphene slurry. USE - The anticorrosive coating is useful for preventing corrosion of cold exchange equipment of petroleum refining equipment. ADVANTAGE - The anticorrosive coating has excellent high-temperature resistance, impact resistance, chloride ion penetration resistance and thermal conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the anticorrosive coating, which involves: (1) weighing each raw material component according to the weight ratio, mixing bisphenol S epoxy resin, bisphenol A epoxy resin and portion of solvent, adding to a reaction kettle, stirring, heating until the resin is completely dissolved, cooling to room temperature, adding boron phenolic resin modified tetrafunctional epoxy resin solution, silane resin modified quartz powder, filler and other additive, carrying out high-speed mixing, when the material liquid temperature reaches 45-55 degrees C, heating and continuously stirring for 1 hour, adding other additive, and grinding with a sand mill for 0.5-1 hour to make a material (A); (2) adding the boron phenolic resin, modified amino resin, film-forming aid and other solvent to a dispersion tank, and dispersing at high speed until completely dissolved to form resin liquid material (B); and (3) evenly mixing and stirring the prepared materials (A) and (B) and graphene slurry.
