Abstract

The invention discloses a fingerprint-resistant paint and a preparation method thereof. The fingerprint-resistant paint comprises the following components in parts by weight: 50-60 parts of acrylic resin emulsion (solid content is 45%), 5-8 parts of silicasol, 4-7 parts of mixed wax slurry, 0.2-1 part of defoaming and leveling agent, 4-6 parts of film-forming cosolvent and 30-40 parts of deionized water. The fingerprint-resistant paint takes water as the main solution, and is added with aqueous high-molecular organic substances which have superior properties and are harmless to human bodies. A low surface tension structure is formed on surface of the added filler and the paint film, thereby greatly enhancing the fingerprint resistance of the steel sheet. The fingerprint-resistant paint can be coated on the surface of a hot galvanized steel sheet or electrogalvanized steel sheet in a mode of dip coating, curtain coating, roller coating, gasket coating or the like, so that fingerprints can not be attached to the surface. In addition, the paint is environment-friendly.

Description

Technical field [0001] The invention relates to a paint coated on the surface of a galvanized steel sheet and a preparation method thereof, in particular to a paint coated on the surface of a galvanized steel sheet which can resist fingerprints and a preparation method thereof. Background technique [0002] Galvanized steel sheets are usually divided into two categories: hot-dip galvanized steel sheets and electro-galvanized steel sheets. Galvanized steel sheets are widely used in light industry, home appliances, construction, home industry and automobile manufacturing due to their good anti-corrosion properties and decorative functions. It is a product with high added value. In the galvanized steel sheet, although the steel exposed to the moist air is susceptible to corrosion, due to galvanizing, it can rely on the metal zinc that forms a dense oxide protective layer in the air to protect the internal steel structure. In the case of scratches, the relatively active galvanized ...
