Abstract

The invention discloses a water-based amino baking varnish for vacuum coating. The water-based amino baking varnish is prepared from, by mass, 40 to 50 percent of water-soluble epoxy modified acrylic resin, 9 to 15 percent of a cross-linking agent, 2 to 8 percent of a miscible transparent dye, 8 to 16 percent of a hydrophilic alcohol ether cosolvent, 0.1 to 0.5 percent of a defoaming agent, 0.1 to 0.5 percent of a leveling agent and 10 to 30 percent of deionized water. According to the water-based amino baking varnish for vacuum coating, the water-soluble epoxy modified acrylic resin is used as a main body, and the cross-linking agent, the hydrophilic cosolvent, the leveling agent, the defoaming agent, the miscible transparent dye and deionized water in a certain proportion are prepared as auxiliary film-forming materials. By adjusting the proportion and dosage of the auxiliary film-forming materials, the prepared water-based amino baking varnish for vacuum coating has excellent adhesive force, weather resistance, friction resistance and recoatability, and has good construction tolerance and water dilutability.

Description

technical field [0001] The invention relates to the technical field of paints, in particular to a water-based amino baking varnish for vacuum coating. Background technique [0002] Vacuum coating is a technology that produces thin film materials by physical methods. The atoms of the material in the vacuum chamber are separated from the heating source and hit the surface of the object to be plated. This technology was first used to produce optical lenses, such as nautical telescope lenses. Later extended to other functional films, disc aluminum, decorative coating and surface modification of materials, etc. [0003] A water-based amino baking varnish is often attached to the surface of the vacuum coating. The existing water-based amino baking varnish has problems such as poor friction resistance, long drying time, and poor adhesion. Contents of the invention [0004] The purpose of the present invention is to provide a water-based amino baking varnish for vacuum coating ...
