Title:
STEEL BAR CORROSION-RESISTANT COATING FOR MARINE CONCRETE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/141935
Kind Code:
A1
Abstract:
A preparation method for a steel bar corrosion-resistant coating for marine concrete, comprising the following steps: (1) pretreating the surface of a steel bar; (2) preparing self-healing corrosion microcapsules; (3) preparing a cathodic electrophoresis coating; (4) carrying out cathodic electrophoresis; and (5) carrying out curing. The electrophoresis coating contains the self-healing corrosion microcapsules, metal powder, and graphene oxide powder. The corrosion resistance of the coating is improved under the co-action of the self-healing property of the self-healing microcapsules and cathodic protection.
