Wear-resistant corrosion-resistant powder paint for aluminum alloy template and preparation process thereof

Abstract

The invention discloses wear-resistant corrosion-resistant powder paint for an aluminum alloy template and a preparation process thereof. The powder paint is prepared from the following raw materialsin parts by weight: 20-25 parts of polyvinylidene chloride, 1.5-4 parts of titanium dioxide powder, 1.5-4 parts of silicon dioxide powder, 3-5 parts of stearic acid, 4-8 parts of a reinforcing agent,1.6-2 parts of silicone oil and 2-4.5 parts of polyethylene wax. The powder paint contains the stearic acid. When the powder paint is smeared on the aluminum alloy template, a layer of hydrophobic film is formed on the surface of the aluminum alloy template, and water is prevented from penetrating through the coating film to be in contact with the aluminum alloy template, so that the corrosion resistance of the aluminum alloy template is improved. The reinforcing agent is prepared on the preparation process of the powder paint and contains a benzoquinone structure, the benzoquinone structure has good light shielding property, and the reinforcing agent contains a hindered phenol structure, so that light resistance of the powder paint is improved.

Problems solved by technology

[0002] Aluminum formwork is a new generation of formwork system after wood formwork and steel formwork. Aluminum formwork is designed according to the modulus and extruded by special equipment. It can be freely combined according to different structural sizes. The design, development and construction application of aluminum formwork is A major development in the construction industry. The application of aluminum formwork system in the construction industry has improved the construction efficiency of housing construction projects, including building materials. When the aluminum alloy formwork is used, a layer of paint will be applied to the surface to protect the aluminum alloy formwork. , The coatings used for aluminum alloy templates are mostly powder coatings. The traditional powder coatings have general wear resistance. Protect the aluminum alloy formwork, and the coating film will be eroded by moisture. The corrosion of the aluminum alloy formwork under long-term moisture erosion seriously affects the use of the aluminum alloy formwork, and it often receives sunlight during the use of the aluminum alloy formwork. When the paint film on the surface of the alloy formwork receives sunlight, it will react photochemically with the light, resulting in damage to the paint film, which cannot protect the aluminum alloy formwork, thereby reducing the service life of the aluminum alloy formwork
