NOVELTY - The preparation method of graphene-containing heat-shrinkable anticorrosive pipe involves inspecting inner and outer surfaces of a steel pipe which needs to be anticorrosive, transferring the steel pipe to an internal derusting machine, shot blasting and removing rust in the inner surface of the steel pipe, descaling the inner surface and outer surface of the steel pipe, placing the pipe in an intermediate frequency heating furnace after descaling, heating the pipe, and uniformly spraying graphene conductive anticorrosive coating on the inner and outer surfaces to complete molding. USE - Preparation method of graphene-containing heat-shrinkable anticorrosive pipe (claimed). ADVANTAGE - The method enables preparation of graphene-containing heat-shrinkable anticorrosive pipe with excellent adhesive force, impact strength, and use performance. DETAILED DESCRIPTION - The preparation method of graphene-containing heat-shrinkable anticorrosive pipe involves inspecting inner and outer surfaces of a steel pipe which needs to be anticorrosive, transferring the steel pipe to an internal derusting machine, shot blasting and removing rust in the inner surface of the steel pipe so that the inner surface of the steel pipe is cleaned, descaling the inner surface and outer surface of the steel pipe to ensure that the outer surface of the steel pipe is clean, placing the steel pipe in an intermediate frequency heating furnace after descaling, heating the steel pipe at 230 degrees C, and uniformly spraying graphene conductive anticorrosive coating on the inner and outer surfaces to complete molding, where the graphene conductive anticorrosive coating comprises modified graphene, polypropylene vinyl acetate, aqueous epoxy resin, and potassium silicate.
