Abstract

The invention discloses a flash powder coating, which consists of the following ratios: 60-80% of raw material resin and curing leveling system, 0-20% of pigment, 0-30% of filler, 0.2-0.4% of degassing agent, flash pigment 0.1-5%, orientation aid 0-0.2%, powder flow accelerator 0.1-0.2% According to the process: first, the first four raw materials are mixed at high speed → melt extrusion → tablet crushing → milling and sieving to obtain the sieved product , and then evenly dry-mix the sieve with the last three raw materials, and get the finished product after sieving.

Description

Technical field [0001] The invention relates to a flash powder coating, belonging to the technical field of powder coatings for electrostatic coatings. Background technique [0002] Art paint is one of the research directions of paint. At present, art paint mainly includes sand wrinkle, orange pattern, hammer pattern, floating flower, flash and other types. Coatings made of pearlescent, metallic and other effect pigments are increasingly popular with people for their good appearance and decorative effects. They are widely used in the decoration of household appliances, hardware tools, instruments and even various medium and high-end vehicles. Paint metal coatings have therefore developed rapidly. However, the problems of environmental pollution, low mechanical properties of the coating and high comprehensive construction costs have accelerated the pace of technical personnel to develop related metal powder coatings. Art-based metal powder coatings have been developed rapidly. Its...
