A preparation method for a corrosion-resistant coating of a reinforcing steel for marine concrete, comprising the steps: (1) pretreating the surface of a reinforcing steel; (2) preparing self-repairing corrosion microcapsules; (3) preparing a cathodic electrophoresis coating; (4) carrying out cathodic electrophoresis; and (5) curing. The electrophoresis coating of the present invention contains the self-repairing corrosion microcapsules, metal powder, and graphene oxide powder. The corrosion resistance of the coating is improved under the co-action of the self-repairing properties of the self-repairing microcapsules and cathodic protection. The corrosion-resistant coating has excellent adhesion and corrosion resistance, prolonging the service life of reinforcing steel. It is widely used for the protection of reinforcing steels for marine concrete, and also for the protection of metal structures in general environment.
