Abstract
A composite coating includes a water-based two-component polyurethane topcoat and a nano-silicon varnish. The coating method of the composite coating on the slide includes uniformly stirring the water-based two-component polyurethane topcoat, then coating the surface of the slide with the water-based two-component polyurethane topcoat; rolling patterns on the surface of the water-based two-component polyurethane topcoat by using a sponge embossing roller before the surface of the water-based two-component polyurethane topcoat dries; and after rolling is completed, place to dry, and then coat the nano-silicon varnish to form a smooth surface after confirming the surface of the water-based two-component polyurethane topcoat has dried. The sponge embossing roller is used for rolling the patterns before the water-based two-component polyurethane topcoat has not dried, so that the contact area with the nano-silicon varnish is increased, indirectly promoting the adhesion ability of the nano-silicon varnish and ensuring the firmness of the composite coating.
