A high-gloss white uv coating construction technology

Abstract

The invention relates to a paint construction technology, in particular to a high-brightness white UV coating construction technology. A high-gloss white UV coating construction process, comprising the following steps: sanding, roll-coating UV primer, roll-coating pure white UV primer, roll-coating sanding UV primer, then sanding, dust removal, and curtain coating transparent UV primer, wetting before flow coating, flow coating of pure white high-gloss UV topcoat, complete lamination after drying. The construction process of the present invention does not need to be sprayed, has no paint mist, and is produced in batches. Since the surface of the panel is coated with UV white paint, the color is very uniform and the adhesion is strong. The most important thing is that the surface does not use transparent varnish, so the coating It has strong resistance to yellowing, basically does not change color, and the grade reaches five grades.

Description

technical field [0001] The invention relates to a paint construction technology, in particular to a high-brightness white UV coating construction technology. Background technique [0002] At present, the high-gloss white UV decorative panels on the market are generally made of white PU as the base, sprayed with transparent UV paint as the top coat or roller coated with white UV as the primer, and then poured with transparent UV as the top coat. The process of white PU as the base and transparent UV paint as the top coat is often accompanied by the volatilization of harmful substances during the production process, which seriously affects the health of the body, and the production cycle is long, prone to cracking, orange peel and other problems; roll coating Although white UV is used as a primer, and then transparent UV is used as a topcoat process, although the problems of environmental protection and bursting have been solved, the problem that white is the most prone to yel...

Problems solved by technology

The process of white PU as the base and transparent UV paint as the top coat is often accompanied by the volatilization of harmful substances during the production process, which seriously affects the health of the body, and the production cycle is long, prone to cracking, orange peel and other problems; roll coating White UV is used as a primer, and then transparent UV is used as a topcoat process. Although the environmental protection and bursting problems have been solved, the problem that white is the most prone to yellowing has not been solved.
