Problems solved by technology

[0003] At present, there are no mature mirror silver coating products in China. Most of the current mirror silver coatings are products from American PPG, German Lankwitzer Lackfabrik or Taiwan-funded enterprises. The products are expensive and cannot meet the wet-on-wet spraying process on the market. Require
The existing mirror silver coatings in China mainly use self-drying types such as nitrocellulose, cellulose acetate butyrate (CAB), thermoplastic acrylic and thermosetting isocyanate resins and hydroxyl acrylic resins. The compactness of the paint film is poor. After that, the mirror effect will be lost, and the protective effect of the paint film will be lost if it is not covered.

Abstract

The invention relates to a formula of a mirror silver coating, a mirror silver resin forming the mirror silver coating, and the preparation methods for the mirror silver coating and the mirror silver resin. According to the formula, the mirror silver coating consists of the following components in part by mass: 2 to 20 parts of mirror silver resin, 5 to 30 parts of butanol, 5 to 20 parts of isopropanol, 20 to 55 parts of acetic ether, 10 to 20 parts of butyl acetate, 5 to 30 parts of propylene glycol methyl ether acetate, and 0.5 to 3 parts of electroplating silver slurry; the mirror silver coating is high in decoration; compared with the conventional cyanogen-containing electroplating, the method for electroplating by using the mirror silver coating has the advantage that environment is polluted slightly; the selected raw materials have special structures and are low in cost, the mirror silver coating can replace a foreign product completely due to the performance, and the price of the mirror silver coating is more than 50 percent lower than that of an imported product; and the mirror silver coating has a super electroplating effect, is high in adhesion, and can meet the characteristics of a wet to wet spraying process; and a paint film can be machined and cut.

Description

Technical field [0001] The invention relates to a paint, in particular to a mirror silver paint, and also relates to a silver resin for the composition of the mirror silver paint. The invention also relates to a method for preparing the silver paint of the mirror and the silver resin for the composition, belonging to the technology of paint field. Background technique [0002] Electroplated silver (mirror silver) is a very special metal pigment with electroplating effect, so it is often called "electroplated silver" in the market. Vacuum aluminized metal pigments are produced through a special vacuum aluminized process. Compared with aluminum pigments produced by traditional methods (such as ball milling), this pigment is a suspension composed of very smooth and very thin scaly aluminum flakes . This kind of pigment has a high reflective effect, and its "radial ratio", which is the ratio of the average particle diameter to its thickness, is relatively much larger. [0003] At pr...
