Document Type and Number:
WIPO Patent Application WO/2021/068506
Kind Code:
A1
Abstract:
Provided are a water-based anticorrosive coating based on graphene oxide and a preparation method therefor, relating to the field of surface engineering technology. The coating provided in the present invention comprises the following components in parts by mass: 40-45 parts of an aqueous resin, 10-12 parts of graphene oxide, 10-12 parts of silicon carbide, 6-8 parts of a dispersing agent, 3-5 parts of an aluminum powder, and 120-200 parts of water. By means of the combined action of the hexagonal honeycomb structure of graphene oxide and the aluminum powder, the corrosion resistance of the coating layer is improved in the present application. The aluminum powder and the silicon carbide are combined to form an aluminum-silicon hybrid structure, thereby further improving the compactness, high-temperature resistance and corrosion resistance of the coating layer. Therefore, the water-based anticorrosive coating based on graphene oxide provided in the present invention has an excellent anticorrosive capacity, and is water-based, such that same is environmentally friendly and is low in cost. In addition, by means of the preparation method provided in the present invention, the bonding strength of the graphene oxide and the aluminum powder is very high, thereby efficiently improving the anticorrosive capacity of the coating; and the method is simple and easy to control.
