Problems solved by technology

[0002] Traditional metal powder coatings are mainly produced by dry mixing method. However, the dry mixing method is difficult to spray because the base powder cannot completely wet and wrap the metal pigment, and because of the difference in particle size, specific gravity, and chargeability between the two, the powder Coating bonding technology solves this problem by using the principle of fusion bonding of primer and metallic pigments. However, the process of powder coating bonding technology is complicated, the utilization rate of metallic pigments is low, and the quality of coatings produced between batches is not stable. , the reproducibility is not good, especially when producing wrinkled metal powder coatings, the texture effect will be changed after bonding

Abstract

The invention discloses a metal powder coating. The metal powder coating comprises, by weight, 30 parts of epoxy resin, 30 parts of polyester resin, 0.07 part of a wrinkling agent, 30 parts of a filler, 0.8 part of carbon black, 0.4 part of wax powder, base powder and a metallic pigment, wherein the ratio of the base powder to the metallic pigment is 1000:5. The invention also provides a preparation process of the metal powder coating. The preparation process of the metal powder coating is simple in flow, and effectively improves the production efficiency; and a molten material and the metallic pigment are mixed, so that the utilization rate of the metallic pigment is improved, the quality stability of the coating between batches is effectively ensured, and the textures of the wrinkle metal powder coating are consistent.
