As shown in figure 1, the adhesiveness, alkali resistance and water resistance of the paint can be improved by adding the curing agent, the hardness of the paint surface can be adjusted, the surface of the aluminum material is not easy to be stained with the paint surface, the sprayed surface of the aluminum material can achieve the antibacterial effect by adding silver ions, and the product has strong adhesiveness, is not easy to fall off and has better anti-collision effect than resin paint. The product adopts the high-temperature solidification surface to achieve the enamel effect, has the advantage of conveniently protecting the aluminum profile, and adopts the main material of carboxymethyl cellulose by adding the flatting agent into the water-based paint, so that the phenomena of fish eyes and shrinkage holes can be eliminated, the tension of the surface of an aluminum coating film is reduced, the product has excellent flatting effect, the dispersibility of pigment can be increased, the production cost is reduced, the wetting of the aluminum material can be improved, the surface of the aluminum profile is smoother, the optical property of the surface of the aluminum profile film can be changed by adding the flatting agent, the gloss of the aluminum profile film is reduced, the eyesight of a user can be conveniently protected, the raw materials of the water-based paint can be more uniformly mixed by a premixing step, the water-based paint is not easy to fall off from the aluminum profile, and the service life of the water-based paint can be prolonged by being placed in a glass bottle for preservation in a shade place.
The foregoing invention has been generally described in great detail, but it will be apparent to those skilled in the art that modifications and improvements can be made thereto. Accordingly, it is intended to cover modifications or improvements within the spirit of the inventive concepts.
Claims (8)
