[0002] Water-based coatings are coatings that use water as a solvent or dispersion medium, including water-soluble coatings, water-diluted coatings, and water-dispersible coatings. They have the advantages of non-stickiness and durability. The texture is sluggish and not smooth; the existing environmentally friendly water-based coatings require a large amount of expensive resin and titanium dioxide, which is not conducive to controlling production costs; the existing environmentally friendly water-based coatings are prone to the problem of gray and black hue

Abstract
The invention discloses environment-friendly water-based coating and a preparation process. The formula of the coating comprises resin, titanous powder, titanium dioxide, a heat stabilizer, silicon aluminum powder, glass powder, nanometer silicon powder, water, a coloring agent, a defoaming agent, a leveling auxiliary agent and a dispersing agent. The preparation process comprises the following steps: step 1, preparing raw materials; step 2, preparing an emulsion; step 3, preparing coating; step 4, filling. In the first step, the resin is one or a mixture of two of acrylic resin and polyurethane resin; in the second step, a dispersion machine is a high-speed dispersion machine, and a sand mill is a horizontal sand mill. Compared with existing environment-friendly water-based coating, the disclosed coating has advantages that: the problem that coating is low in strength after being cured is solved by adding the glass powder and the nanometer silicon powder; the titanous powder is added to replace a certain amount of titanium dioxide and resin, so that the production cost is reduced; and the problem of gray black color change of the paint is avoided by means of increasing the process temperature, reducing the stirring speed and the like.
Description
Technical field [0001] The present invention relates to the field of coating materials, in particular an environmentally friendly aqueous coating and preparation process. Background technique [0002] Water-based coating is a coating of water-based solvent or dispersion medium comprising a water-soluble coating, a water diluent coating and aqueous dispersible coating, having non-viscosity and durability, but the existing environmentally friendly water-based coating is insufficient, and The texture is sluggish; the existing environmentally friendly waterborne coating requires a large number of expensive resins and titaniumwhite powder, which is not conducive to controlling production costs; existing environmentally friendly waterborne coatings are prone to color phase change. Inventive content [0003] It is an object of the present invention to provide an environmentally friendly aqueous coating and a preparation process to solve the problems raised in the above background.
