Automatic perspiration-removing varnish

Abstract

The invention discloses automatic perspiration-removing varnish. The automatic perspiration-removing varnish comprises the following components in percentage by mass: 50 to 70% of silicone modified acrylic resin, 5 to 25% of silicone modified polyester resin, 5 to 25% of a closed polyurethane curing agent and 0.5 to 2.5% of an additive. The automatic perspiration-removing varnish coats the surface of coated color stainless steel, the thickness of the automatic perspiration-removing varnish is 5 to 15 microns, the baking temperature of the automatic perspiration-removing varnish is 195 to 200 DEG C, the baking time of the automatic perspiration-removing varnish is 150 to 180 seconds, and then the automatic perspiration-removing varnish is naturally cooled or subjected to blast cooling after dried. The automatic perspiration-removing varnish disclosed by the invention belongs to baking varnish which has convenient flow line production and quick coating. The automatic perspiration-removing varnish coats the color coated surface of a stainless steel plate to quickly and automatically remove perspiration and show a mirror surface result and removes the perspiration after being naturally aired for 5 seconds. The automatic perspiration-removing varnish disclosed by the invention is easily attached to a coating layer, and is an organic coating which is excellent in gloss and color retention, and outstanding in medium resistance and anti-fouling and anti-perspiration effects, and further has the characteristics of weather resistance, high hardness, high toughness, high adhesion, high distinctness, scratch resistance, fingerprint resistance and medium resistance.

Description

technical field [0001] The invention belongs to the field of polymer resin synthesis, specifically relates to the field of paint development for colored stainless steel substrates, in particular to an automatic sweat-eliminating varnish for the surface of coated colored stainless steel plates. Background technique [0002] Coated color stainless steel plate, with bright colors, is widely used in high-end decoration fields, such as hall wall panels, ceilings, elevator car panels, carriage panels, architectural decoration, signboards, etc. [0003] In order to keep the gloss and color of the coated colored stainless steel plate for a long time, clean and bright mirror decoration effect, it is necessary to protect the coated surface, and it is the most economical and effective way to coat the surface with a layer of varnish; the varnish coating can protect The coated colored stainless steel plate can automatically eliminate sweat stains, especially after being pressed by human ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the above-mentioned prior art, the present invention aims to solve the problem that the colored stainless steel substrate cannot automatically eliminate sweat stains after being pressed by fingers to restore brightness, and provides an automatic sweat stain varnish, which is coated on the surface of stainless steel plates to automatically eliminate stainless steel stains. Sweat stains on the surface of the board
