Problems solved by technology

[0004] However, in order to ensure the performance indicators of color-coated panels, the current color-coated panels are all chromium-containing products, and the passivation agent for chemical pretreatment and the anti-rust pigment that provides early corrosion resistance in the primer all contain hexavalent Cr. Chromium-containing products around the world will be forced to be chrome-free, so it is imperative to develop chrome-free pretreatment agents and chrome-free antirust coatings with excellent performance

Abstract

The invention discloses a colorful fingerprint-resisting coating, which comprises the following components in parts by mass: 50-70 parts of water-based macromolecular latex, 5-10 parts of deionized water, 15-25 parts of pigment, 5-10 parts of resin, 0.1-1 part of wetting agent, 0.5-1 part of flatting agent, 0.1-1 part of antifoaming agent and 1-5 parts of silane compound. Accordingly, the invention discloses a preparation method and a use method of the colorful fingerprint-resisting coating. The colorful fingerprint-resisting coating does not contain metal ions, and has excellent environmental conservation, decay resistance and fingerprint resistance.

Description

technical field [0001] The invention relates to a coating composition, a preparation method and a usage method thereof, in particular to a fingerprint-resistant coating composition, a preparation method and a usage method thereof. Background technique [0002] The color-coated sheet production technology was first created in the United States in 1927. Since the 1960s, the production of color-coated sheets has developed rapidly. Among them, the United States and Japan have the most color-coated sheet production lines, the largest production capacity, and the most complete varieties and specifications. In foreign countries, color-coated panels have been widely used in construction, home appliances, automobile manufacturing and other industries. With the growth of color-coated board consumption and the continuous expansion of application fields, as well as the continuous improvement of users' requirements on the quality and performance of their varieties, various new technolog...
