Problems solved by technology

These parts have high requirements on paint coating performance, which makes it difficult for some conventional resin film formers to spray electroplated silver coatings with high appearance metal effects
[0004] In Chinese patent CN 103319966, the electroplated silver paint made of modified acrylic resin (including nitrocellulose modified acrylic resin and cellulose acetate modified acrylic resin) needs to be baked at a temperature of 65-80°C for 30 minutes to obtain Paint film, although this kind of resin can get a better appearance, it is difficult to spray the protective varnish on the surface without completely baking and drying, otherwise the solvent on the surface of the varnish will penetrate the electroplating silver coating layer, and electroplating silver The uniform arrangement of aluminum powder affects the flakes of aluminum and silver flakes from flat to established in the resin coating film. Finally, after the varnish is baked, the electroplated silver coating loses the metal mirror effect, so this type of resin cannot achieve wet spraying. Wet effect (that is, without baking,

Abstract

The invention discloses a silver electroplating coating composition. The composition comprises the following components in parts by weight: 7-30 parts of a high-molecular metal aligning agent, 0.1-10 parts of hyperbranched hydroxyl resin, 1-6 parts of aluminium silver paste, 60-300 parts of a solvent, and 1.011-14 parts of an auxiliary agent. The invention also discloses a preparation method of the silver electroplating coating combination. The method comprises the following steps: 15-90 parts of the solvent is added into 0.1-10 parts of hyperbranched hydroxyl resin in a first container; 20-60 parts of the solvent is added into 1-6 parts of the aluminium silver paste in a second container, 1.011-14 parts of the auxiliary agent is added with uniform stirring, and uniform stirring is carried out continuously; a mixture in the second container is added into the first container with uniform stirring; finally, 7-30 parts of the high-molecular metal aligning agent and 25-150 parts of the solvent are added with uniform stirring, and the silver electroplating coating composition is obtained. The silver electroplating coating composition has the characteristics of high performance as well as good appearance and brightness.

Description

technical field [0001] The invention belongs to the technical field of paint preparation, and relates to a paint composition, a preparation method and an application thereof, in particular to an electroplating silver paint composition, a preparation method and an application thereof. Background technique [0002] With the improvement of people's living standards, the appearance and quality requirements of high-end products are getting higher and higher. Electroplated silver paint is currently the top coating material in the world, and is widely used in the coating of high-end products such as electronic products, handicrafts, automobiles, and automobile wheels. Products coated with electroplating silver paint can achieve the effect of electroplating.
