Abstract

The invention relates to an organic and inorganic mixed fingerprint-resistance coating and a preparation method thereof. The coating is prepared from the following chemical components in percentage by weight: 40 to 70 percent of aqueous resin, 3 to 10 percent of modified silica solution, 2 to 15 percent of amino resin, 2 to 10 percent of polyisocyanates, 1 to 5 percent of mineral salt, 1 to 6 percent of aqueous polyethylene wax pulp, 1 to 9 percent of adhesion promoter, 0.1 to 0.5 percent of flatting agent, and 10 to 40 percent of deionized water. And the total weight percentage of the raw materials is 100 percent. The organic and inorganic mixed fingerprint-resistance coating prepared by the method does not contain metal ions which cause pollution to the environment. The coating can be coated on an electrogalvanized steel sheet, hot-dip galvannealed sheet, tin-plated steel sheet or cold-rolled steel sheet, and after being coated, the coating can be baked for only 8 to 15 seconds to be solidified into a transparent coating with high fingerprint resistance, corrosion resistance, high hardness, scraping resistance, conductivity, self-lubricating performance, coating performance and the like.

Description

technical field [0001] The invention relates to a metal surface protective coating composition, in particular to an organic / inorganic hybrid anti-fingerprint coating and a preparation method thereof. Background technique [0002] In recent years, galvanized steel sheets have been widely used in industries such as home appliances, automobiles, office supplies, and toys. With the continuous improvement of people's quality of life, the products used are not only required to be aesthetically pleasing, but also environmentally friendly. Fingerprint-resistant steel plate is a high value-added surface treatment product. Compared with the general bare galvanized steel plate, it not only has fingerprint resistance, but also has corrosion resistance, electrical conductivity and repaintability. Today, the market demand for anti-fingerprint steel products is increasing day by day, which also promotes the research on anti-fingerprint processing technology and the development of new appli...
