Problems solved by technology

Many metal equipment in life are generally installed indoors or in the open air. If installed outdoors, they will be affected by harsh weather conditions for a long time and will be rusted and corroded. If they cannot be repaired or replaced in time, it may cause equipment failure and affect Safe and normal operation of equipment
Now there are many methods to inhibit metal corrosion. Coating anticorrosion is an effective and common method. However, traditional coating anticorrosion has insufficient strength and poor temperature resistance. It is easy to crack under the lower surface, resulting in the decline of the anti-corrosion effect of the coating or even failure.

Abstract

The invention discloses an anticorrosive paint for carbon nanotube-containing metal. The anticorrosive paint is composed of epoxy resin, organic bentonite, dibutyl phthalate, titanium dioxide, mediumchrome yellow, talcum powder, barium sulfate, zinc oxide, carbon nanotubes, temperature-sensitive powder and matched assistants. According to the invention, a special high-strength one-dimensional linear structure of the carbon nanotubes is utilized to form a high-strength interlaced reticular structure in the coating, so that the coating is more compact; and meanwhile, by utilizing the nano effect of the carbon nanotubes, the binding force between the coating and the material is improved, pores in the coating are reduced, and a solution is prevented from entering the coating, so that the weather resistance and the corrosion resistance of the coating are effectively improved. The material is environmentally friendly, the production process is environmentally friendly, the obtained paint film is excellent in water resistance and corrosion resistance, high in bonding strength and excellent in alkali resistance and corrosion resistance, the application range of the paint is greatly widened, and the cost performance of the paint is greatly improved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to carbon nanotube anticorrosion coatings for metals. Background technique [0002] Metal rusting is the most common and costly form of corrosion. Many metal equipment in life are generally installed indoors or in the open air. If installed outdoors, they will be affected by harsh weather conditions for a long time and will be rusted and corroded. If they cannot be repaired or replaced in time, it may cause equipment failure and affect The equipment operates safely and normally. Now there are many methods to inhibit metal corrosion. Coating anticorrosion is an effective and common method. However, traditional coating anticorrosion has insufficient strength and poor temperature resistance. Cracks are prone to occur under the environment, resulting in a decline in the anti-corrosion effect of the coating or even failure. [0003] In the present invention, nano-scale multi-walled c...
