Coating capable of replacing electroplated decorative chromium layer

Abstract

The invention discloses a coating capable of replacing an electroplated decorative chromium layer, which comprises the following components in percentage by weight: 20 to 30 percent of acrylic resin, 5 to 10 percent of melamine resin, 29 percent of dimethylbenzene, 3 to 8 percent of diacetone alcohol, 3 to 8 percent of n-butyl alcohol, 1 to 5 percent of alcohol, 1 to 5 percent of butyl acetate, 1 to 5 percent of isobutyl acetate, 1 to 5 percent of ethylene glycol monobutyl ether, 1 to 5 percent of silicon dioxide, 1 to 5 percent of epoxy resin and 5 to 10 percent of other components. The invention aims to overcome the disadvantages in the prior art and provide a coating with simple components and capable of replacing the electroplated decorative chromium layer. The decorative effect of the coating is very similar to that of electroplated chromium and can replace the apparent effect of the electroplated chromium; when coated and applied to products, the coating has good adhesive force, rigidity, wear resistance, corrosion resistance and anti-scraping performance; and the coating is coated on the metal surface after the polishing treatment, and an appearance similar to the electroplated chromium can be generated by mixing the coating with the own gloss of the metal.

Description

technical field [0001] The invention relates to a paint, which can replace the electroplated decorative chrome layer. Background technique [0002] Chrome plating is a traditional metal surface treatment process. Electroplated chrome coatings can be divided into hard chrome coatings, decorative chrome coatings, colored chrome coatings, etc. Among them, the surface of the decorative chrome plating is silvery white, bright and beautiful in color, durable and rust-free, which is a commonly used surface treatment method for exterior parts. However, due to the poor environmental performance of the electrochrome plating process, its use has been limited. [0003] In the last century, many coatings with special properties were researched and developed internationally. Whether the electroplating chrome layer can be replaced by a paint coating is a subject that many surface treatment workers are studying. [0004] For a product that requires decorative chrome plating, our company...
