Problems solved by technology

Coatings made of effect pigments such as pearlescent and metal are increasingly popular with people for their good appearance and decorative effects. Therefore, paint-based metal coatings have been developed rapidly, but there are always environmental pollution, low coating mechanical properties and comprehensive construction. Problems such as high cost have accelerated the pace of development of related metal powder coatings. Art-type metal powder coatings have won people's favor for their excellent appearance, outstanding concave-convex touch, and excellent physical and mechanical properties.

Abstract

The sand grain metal powder paint consists of resin and curing leveling system 60-80 wt%, sand grain agent 0.1-0.5 wt%, pigment 0-20 wt%, stuffing 0-30 wt%, metal pigment 0.5-5 wt%, and powder flowing promoter 0.1-0.2 wt%. It is prepared through the technological process including the steps of high speed stirring to mix, fusing and extruding, tabletting and crushing, grinding into powder and sieving, and dry mixing.

Description

technical field [0001] The invention relates to a metal powder paint with sand pattern, which belongs to the technical field of powder paint for electrostatic coating. 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 effect pigments such as pearlescent and metal are increasingly popular with people for their good appearance and decorative effects. Therefore, paint-based metal coatings have been developed rapidly, but there are always environmental pollution, low coating mechanical properties and comprehensive construction. Problems such as high cost have accelerated the pace of development of related metal powder coatings. Artistic metal powder coatings have won people's favor for their excellent appearance, outstanding concave-convex touch, and excellent physical and mechanica...
