Abstract

The invention discloses an anticorrosion coating for outdoor walls and a preparation method thereof, which is composed of the following components in parts by weight: 10-20 parts of epoxy resin, 1-3 parts of hydroxypropyl methylcellulose, and 1-3 parts of titanium dioxide 2 parts, 5-8 parts of 4-methyl-3-pentenone, 7-12 parts of film-forming agent, 1-2 parts of dodecyl dimethyl betaine, 30-90 parts of water, 3-parts of thickener 5 parts, preservative 2‑5 parts. Wherein, the anticorrosion agent is composed of one of quaternary ammonium salt, tribromophenol, ageratum, eggshell powder, imidazolidinyl urea, citric acid, ethoxylated glyceryl monostearate, sorbitol, and quinoa extract one or several components. The coating prepared by the present invention has the characteristics of anti-corrosion, can effectively inhibit the activity of microorganisms such as bacteria or fungi, and prevent the coating from falling off due to the reproduction of microorganisms. It is suitable for long-term humid environments and solves the problem of existing coatings. It is easy to be corroded and peeled off due to microbial reproduction in a humid environment, and it has an excellent finishing effect while reducing costs.

Description

technical field [0001] The invention relates to the field of coatings, in particular to an anti-corrosion coating for outdoor walls and a preparation method thereof. Background technique [0002] At present, the exterior walls of buildings are generally painted with paint, which can be well bonded to the base material and form a complete and tough protective film when painted on the surface of the object. Architectural paints have decorative, protective, and habitability-improving functions. The proportions of various functions vary depending on the purpose of use. The decorative function is to improve the appearance value of a building by beautifying it. The paint applied on the wall contains less formaldehyde and other substances. Although it is beneficial to human health, it is also easy to breed microorganisms such as bacteria or fungi. In a relatively humid environment, it is easy to slowly corrode the coating, resulting in Coating peeling off. [0003] Therefore, th...
