Powder spray-coating sand pattern paint

Abstract

The invention relates to the field of coat spraying of powder, particularly to a powder spray-coating sand pattern paint, which comprises, by weight, 45-60 parts of a polyester resin, 7-9 parts of a curing agent, 0.5-1.5 parts of a fluorine-free sand pattern agent, 4-6 parts of a silicon-free leveling agent, 10-20 parts of titanium dioxide, 5-10 parts of an adhesion promoter, 10-18 parts of barium sulfate, 0.1-0.7 part of bentonite, and 0.05-0.5 part of an electric power increasing agent. According to the present invention, various components of the system are regulated, the fluorine-containing material, the silicon-containing material and other low surface energy aids are completely eliminated in the used components, the surface energy of the curing film is increased within the permissible range, and when the re-spraying is required due to the generation of the quality defect on the sand pattern surface, the combination of the sand pattern paint and the cured sand pattern surface is easily achieved.

Description

technical field [0001] The invention relates to the field of powder spraying, in particular to a powder spraying sand pattern paint. Background technique [0002] Sand texture paint means that it does not have the luster of ordinary paint after spraying, and it has a matte texture to the touch, providing a variety of coating effects for furniture. Solvents, additives, these solvents and additives contain a large amount of volatile organic compounds (VOC), and pollute the environment, damage the health of painters, are flammable and explosive, and waste petroleum resources, which has brought great harm to the preparation and use of frosted paint. great inconvenience and potential harm. [0003] The surface of aluminum profiles has good protective and decorative properties after powder spraying. After decades of development, the spraying process of aluminum profiles is becoming more and more perfect, and the rate of spraying finished products is also increasing. In general, ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the problem of delamination between the re-sprayed coating and the previous sand-textured coating when the sand-textured surface has quality defects and needs to be re-sprayed and recoated, the invention discloses a powder-sprayed sand-textured paint, which has good Good adhesion and compatibility, when there are quality defects on the sand grain surface and need to be repainted, the delamination phenomenon between the back spray coating and the previous sand grain coating is completely eliminated
