Abstract

The invention belongs to the field of powder coating and particularly relates to a metal bonding powder coating with a mirror-like silver effect as well as a preparation method and application thereof. The powder coating is prepared by binding base powder and aluminum powder, wherein the base powder is prepared from the following raw materials in percentage by weight: 82 to 85 percent of polyester resin, 12.5 to 15 percent of curing agent, 0.8 to 1 part of leveling agent, 0.3 to 0.5 percent of benzoin, 0.8 to 1 percent of sensitizer and 0.3 to 0.5 percent of antioxidant. The preparation method of the metal bonding powder coating comprises the following steps of uniformly mixing raw materials, performing melt extrusion by an extruder, and performing tabletting, air cooling, grinding and sieving to obtain the base powder; binding the aluminum powder and the base powder. The powder coating disclosed by the invention has the characteristics of good corrosion resistance, good wear resistance, excellent decorating performance, good environment friendliness and no toxicity; the preparation method has the advantages of less investment, low cost, safe production and operation and in accordance with the requirements of large precise product manufacturers at home and abroad; a coating film of the coating has the advantages of high glossiness, high anti-pollution capacity, good greenness, good environmental protection and wide application field.

Description

technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to a metal bonding powder coating with a mirror silver effect, a preparation method and an application thereof. Background technique [0002] The metal powder coating film has a metallic luster, a gorgeous multi-color effect and outstanding protection functions. It is mainly used in indoor and outdoor metal furniture, lamps, handicrafts, range hoods, baby carriages, sports equipment and other industries. According to the appearance gloss effect of the coating film, the flat metal powder coatings can be divided into high gloss, flash (colorful, different colors with corners), and metallic effect. Among them, flash and metal effect products have been promoted and applied to the surface coating of high-end cars, providing colorful appearance decoration for high-end industrial products such as automobiles, home appliances, and instruments. [0003] Silver mirrors are widely u...
