The invention discloses an anti-corrosion static-electricity-conductive coating formed by compounding graphene with polyurethane and a preparation method of the coating.The preparation method comprises the steps of uniformly dispersing graphene slurry in organic solvent under the action of dispersant, and adding the mixture to polyurethane resin, so that the graphene/ polyurethane anti-corrosion static-electricity-conductive coating is obtained.The coating is excellent in static-electricity-conductive performance and salt spray resistance, simple in process and low in cost.The prepared graphene/ polyurethane anti-corrosion static-electricity-conductive coating can be applied to equipment such as an oil tank, an oil pipeline and an automobile.
