Abstract

The present invention is capable to settle the problems that existing fingerprint-proof paints containing chrome cause certain hazard to the environment during the preparation, storage and transportation, particularly to settle the problem of chrome pollution. The invention involves the following chemical compositions: water urethane resin (40 to 70wt percent), silicon dioxide sols (4 to 8wt percent), water teflon wax-dispersion (10 to 20wt percent), deionized water (20 to 40wt percent), EFTOP EF-112 (0.2 to 0.3wt percent), glycol (2 to 3wt percent) and Asekahate B-1019 (0.5 to 0.7wt percent).Water urethane resin is injected in to a reaction kettle, the silicon dioxide and water teflon wax-dispersion are added (agitating at the same time), and film-forming assistant is added, and then other assistants are put into the reaction kettle, and finally, the deionized water is added into the reaction kettle. The fingerprint-proof paint is achieved by agitating continuously for 15 to 30 minutes.

Description

technical field [0001] The invention relates to a coating composition, in particular to an anti-fingerprint coating for manufacturing anti-fingerprint steel plates. Background technique [0002] At present, as people's requirements for quality of life are getting higher and higher, not only are the daily necessities used beautiful, but they are also required to be environmentally friendly and harmless. With the continuous update of automobiles, home appliances, office supplies, etc., the requirements for steel plates are getting higher and higher. Fingerprint-resistant steel plates are an upgraded product and high value-added surface treatment product. Compared with ordinary bare steel plates, it is not only The corrosion resistance of the steel plate is improved, and there are many new properties such as fingerprint resistance, coating and electrical conductivity. In the existing technology, the anti-fingerprint steel plate treatment is to passivate the substrate wire and ...
