Abstract

The flash powder paint consists of resin and curing leveling system 60-80 wt%, pigment 0-20 wt%, stuffing 0-30 wt%, deairing agent 0.2-0.4 wt%, flash pigment 0.1-5 wt%, directional assistant 0-0.2 wt%, and powder flowing promoter 0.1-0.2 wt%. It is prepared through the technological process including high speed mixing the first-mentioned four kinds of material, fusing and extruding, tabletting and crushing, grinding into powder and sieving, mixing the sieved powder with the last three kinds of material, and sieving.

Description

technical field [0001] The invention relates to a flash 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 powd...
