Abstract

The invention relates to the technical field of water-based paint preparation, in particular to a low-temperature baked water-based electrosilvering paint and a preparation method thereof. The electrosilvering paint is prepared from, by mass, 40.0-50.0% of an acrylic acid modified polymer, 10.0-15.0% of silver paste, 10.0-15.0% of a water-soluble organic solvent, 2.5-6.0% of an aluminum powder orientation agent, 0.8-3.0% of a functional assistant, and the balance deionized water. According to the low-temperature baked water-based electrosilvering paint and the preparation method thereof provided by the invention, the low-temperature baked water-based electrosilvering paint has excellent adhesiveness and solvent resistance, and the paint is suitable for coating the surfaces of mobile phones, toys, craft plastic products, cosmetic series, notebook computers and the like. And a paint film formed by coating is flat and bright, bright in color, high in hardness, thick in formed film, excellent in wear resistance, and excellent in adhesiveness and solvent resistance. The silver powder is very good in arrangement, the glossiness measured by a 60-degree photometer can reach about 180GU, and the preparation method is simple and easy for industrial production.

Description

technical field [0001] The invention relates to the technical field of preparation of water-based coatings, in particular to a low-temperature baking water-based electroplating silver coating and a preparation method thereof, so as to be different from traditional vacuum electroplating technology and oily electroplating silver paint. Background technique [0002] Under the background of increasing environmental protection pressure and cost reduction, both the traditional vacuum electroplating silver plating technology and oily electroplating silver paint technology are facing the situation of being eliminated. The traditional vacuum electroplating silver technology consumes electricity, water and pollutes a lot, while the oil-based electroplating silver paint also has strong environmental pollution in the choice of diluent. Facing the current environmental pressure, it is difficult for the two to have an actual market. . In the current electronic information age, electropla...
