Technical Field

The invention discloses an environment-friendly graphene metal rusty heavy-duty anticorrosive paint, and belongs to the field of anticorrosive paints.

Background

On the premise that various devices such as ports, docks, roads, bridges, industrial plants, chemical industrial parks, conveying pipelines, underground pipe galleries and the like cannot move, anticorrosion maintenance work is very difficult, and the engineering quality is very poor. This is because, when the anticorrosion engineering is maintained, the anticorrosion paint needs to be subjected to strict surface treatment, i.e. before painting, rust on the substrate must be thoroughly removed, and at the same time, the anticorrosion paint must be painted in a dry environment, otherwise, the problem of rapid rusting occurs. Rust growth can damage the paint film, rendering the paint film ineffective.

The current painting on the market requires factory sand blasting operation, and a large amount of steel structures and equipment on the spot do not have the condition of factory operation. Therefore, the problems of incomplete rust layer removal and poor corrosion prevention effect still exist in field corrosion prevention construction and maintenance. Therefore, the paint which can be conveniently constructed and maintained on site is urgently needed, can work under the working conditions of serious corrosion and serious humidity, and can exert an ideal anticorrosive effect.

in addition, the added graphene is subjected to TEMPO catalytic oxidation treatment, and has certain advantages in the aspects of physical corrosion prevention and electrochemical corrosion prevention through the unique structural property of the graphene. And the lamellar structures of the graphene are mutually overlapped and staggered layer by layer, a labyrinth shielding structure can be formed in the coating, infiltration, permeation and diffusion of corrosive media can be effectively inhibited, and the physical barrier property of the coating is improved.

Due to the small size effect of the graphene, the graphene can be filled in the defects of the coating, so that the porosity of the coating is reduced, the compactness of the coating is enhanced, and the corrosion factors are further delayed or prevented from being immersed into the surface of the substrate. Have good lubrication action between the graphite alkene layer, the lamellar structure of graphite alkene can be cut apart into many cells with the coating, can reduce coating internal stress effectively, consumes fracture energy, and then improves the pliability, impact resistance and the wearability of coating.

And the conjugated structure of the graphene enables the graphene to have high electron mobility and show good conductivity, and meanwhile, the lamellar structure of the graphene can ensure that better electrochemical contact is formed between the coating layers to form a conductive network and provide better electrochemical protection.
