Abstract

The invention belongs to the field of a powder coating and particularly relates to a metal alike art type powder coating. The metal alike art type powder coating comprises an epoxy resin particle system and a fluorocarbon resin particle system, wherein the epoxy resin particle system contains epoxy resin, an adaptive curing agent A and a flatting agent A; the fluorocarbon resin particle system contains fluorocarbon resin, an adaptive curing agent B and a flatting agent B; and the weight part ratio of the epoxy resin particle system to the fluorocarbon resin particle system is (6-4):(4-6). According to the metal alike art type powder coating, the incompatibility of the flatting agent, the epoxy resin and the fluorocarbon resin is utilized for controlling the distribution the flatting agent, the epoxy resin and the fluorocarbon resin in coating layers, so that the flatting agent is evenly dispersed between the epoxy resin layer and the fluorocarbon resin layer to generate a visual effect of alternative dark and bright, and then a metal alike effect is achieved.

Description

Technical field [0001] The invention belongs to the field of powder coatings, and in particular relates to an artistic powder coating with a metal-like effect and a preparation method thereof. Background technique [0002] Art powder coatings are one of the important research and development directions in the field of powder coatings. At present, art powder coatings mainly include sand, wrinkle, orange, hammer, and metal effects. The artistic powder coating made of pearlescent, metal and various texture agents has a gorgeous or simple effect, has a good appearance and decoration effect, can meet the various decoration effects that people need, and is increasingly loved by people, and more excellent The appearance and visual sense, prominent bumpy touch, and excellent physical and mechanical properties replace liquid coatings and become people's first choice for decoration and decoration. Among them, the metal powder coating can display a bright and luxurious decoration effect, a...
