Abstract

The invention discloses a waterborne metal coating and a preparation method thereof. The water-based metal coating is prepared from 30-50 parts of waterborne acrylic resin, 20-70 parts of nano-titanium silicon carbide modified acrylic resin, 15-25 parts of pigment, 0.5-1.0 part of a rheological agent, 0.1-0.2 part of a pH regulator, 0.5-0.8 part of a defoamer, 3-4 parts of a film-forming additive,0.2-0.8 part of an anti-flash rust agent, 5-10 parts of a cosolvent, 2-4 parts of a wetting dispersant, 0.5-1 part of a base material wetting agent, 1-2 parts of a thickener and 5-10 parts of deionized water. The waterborne metal coating provided by the invention has the advantages of high adhesion, high drying speed and excellent corrosion resistance. Sand blasting treatment or corrosion roughening treatment on the metal surface is not needed, the effect of being same as the effect after sand blasting treatment or corrosion roughening treatment on the metal surface can be achieved, construction difficulty is greatly simplified, and broad market prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based metal coating and a preparation method thereof. Background technique [0002] In order to enhance the weather resistance and corrosion resistance of metals, prolong their service life and increase their aesthetics, surface treatment of metal materials is usually required. There are many kinds of metal surface treatment technologies. At present, the commonly used metal surface treatment technologies mainly include electroplating, electroless plating, and coating technology. The method of using coating technology to protect the metal surface has a long history. The most simple and effective method is to coat the metal surface with a coating with certain properties. After the solvent in the coating evaporates, a layer can be formed on the metal surface. Dense protective film. In recent years, with the rapid development of social economy, the demand for metal coating...
