Problems solved by technology

[0004] However, due to the limitation of the structure of the dye itself, there are defects of poor weather resistance, as well as the problems of poor light resistance and oxidation resistance.
If left in the sun for a long time, often within a few weeks, serious discoloration and peeling will occur, which also limits the application of dyes in the field of outdoor coating
Even if the dye is added to the powder coating to form a transparent powder coating to retain the metallic effect of the metal substrate, the dye will be evenly dispersed on the surface and bottom layer of the powder coating during the extrusion granulation process, and this is still difficult. It is impossible to overcome the problem that dyes are easy to lose color when exposed to outdoors, so it is difficult to popularize and apply dyes in powder coatings, and it also limits the enrichment and promotion of colored powder coatings

Abstract

The invention belongs to the field of powder coating and in particular relates to a powder coating with an imitation anodic oxidation effect. The powder coating comprises an epoxy resin granule system containing epoxy resin, a correspondingly matched curing agent A and dye, and a fluorocarbon resin granule system containing fluorocarbon resin and a matched curing agent B, wherein the ratio of the epoxy resin granule system to the fluorocarbon resin granule system in parts by weight is (6-4): (4-6). The powder coating with the imitation anodic oxidation effect is a novel powder paint for art, which not only maintains the metallic luster of coating base materials, but also endows the coating base materials with bright color, and also has good weather resistance, the coating has excellent appearance decorative effect, the quality stability of the product of each batch is strong, and the product is durable and is very applicable to high end decorative fields.

Description

technical field [0001] The invention belongs to the field of powder coatings, in particular to a powder coating imitating anodizing effect and a preparation method thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, people's requirements for comfort and aesthetics in their own living areas and for home decoration are also getting higher and higher. They not only require good performance, but also have bright colors. color. Powder coating is a decorative material that came into being and developed rapidly in this environment. Powder coatings not only have good performance, but also satisfy people's colors. At the same time, they also make up for the poisoning and environmental problems caused by the addition of organic solvents to liquid coatings. It has the characteristics of no solvent, no pollution, recyclability, environmental protection, energy saving and resource saving, labor intensity reduction...
