Anti-fingerprint coating and spraying method thereof

Abstract

The invention provides an anti-fingerprint coating and a spraying method thereof. The anti-fingerprint coating comprises the following components in parts by weight: 60-70 parts of a polyurethane ultraviolet (UV)-curable coating material, 30-40 parts of a diluent and 3-10 parts of an UV-curable fluorine-containing acrylic acid compound, wherein the diluent is a mixture of butyl acetate, acetic ether and butanone. The method for spraying the anti-fingerprint coating to a product comprises the steps of completely wiping the product by virtue of machine wiping water, drying, spraying a bottom varnish, drying, spraying the anti-fingerprint coating, and carrying out UV irradiation. The anti-fingerprint coating has strong anti-fingerprint capacity and antifouling capacity and is convenient to clean, the operation of the spraying process is convenient, the time is short, and the production efficiency is improved.

It needs to be wiped frequently, and it is not easy to wipe clean. It needs to be wiped with a special cleaning cloth, which seriously affects the appearance of the product.

[0003] The Chinese invention patent with the publication number CN104371527A discloses a coating, a spraying process and its application with the function of sterilizing and anti-fingerprint feel. By adding feel filler, leveling agent, anti-graffiti agent and bactericide to polyurethane resin, the The coating has the functions of hand feeling, sterilization and anti-fingerprint. The anti-graffiti agent is polydimethylsiloxane emulsion. After the coating is sprayed in the spray gun, it needs to be baked at 70-100°C for at least 30 minutes. high, long bake time
