Abstract

The invention discloses a metal powder coating used for outdoor decoration, pertaining to the coating technique field. A preparation method thereof comprises high-speed mixing, melting extrusion, press crushing, grinding and dry mixing treatment; raw materials are according to the following weight proportion: 40 to 60 percent of outdoor pure polyester resin, 4 to 5 percent of TGIC curing agent, 3 to 5 percent of flow agent, 1 to 2 percent of PCR214 metal pigment, 0.1 to 0.3 percent of PC100 metal pigment, 0 to 2 percent of PCR212 metal pigment, 0 to 30 percent of filler, 0.1 to 5 percent of conventional pigment, 0.2 to 0.4 percent of benzoin, and 0.1 to 0.2 percent of fumed silica. The invention has the advantages that the coloring effect can be adjusted by adjusting the pigment portions of base materials powder to form the metal coating with different ground colors; in addition, the invention has the advantages of primary coating film forming, low operation cost, good decoration effect, good weatherability and being applicable for long time outdoor.

Description

technical field [0001] The invention relates to a decorative metal powder coating, which belongs to the technical field of electrostatic coating powder coatings. Background technique [0002] Art paint is one of the research and development directions of paint. At present, art paint mainly includes sand wrinkle, orange pattern, hammer pattern, emboss, flash and so on. Coatings made of pearlescent, metallic and other effect pigments are increasingly popular with people for their good appearance and decorative effects, and are widely used in the decoration of household appliances, hardware tools, instruments and even various medium and high-end vehicles. Therefore, paint-based metal coatings have been developed rapidly, but there are always problems such as environmental pollution, low coating mechanical properties and high comprehensive construction costs, which have accelerated the pace of technicians developing related metal powder coatings. Art-type metal powder coatings a...
