A kind of uv coating construction technology

Abstract

The invention relates to a coating application method, in particular to a UV coating application process. The UV coating application process comprises the following steps of sanding, first-time roller coating of UV primer, roller coating of UV colored paint, second-time roller coating of UV primer, sanding, moistening before shower coating, two times of shower coating of UV high gloss finishing paint, drying and film covering. According to the UV coating application process, paint spraying is not needed, so that paint mist is not generated in the production process; besides, mass production is realized, so that the technical problem that two times of shower coating can not be realized in the prior art is solved, a UV coating is uniform in color, high in adhesive force and production efficiency, and capable of being formed at one time.

Description

technical field [0001] The invention relates to a coating construction method, in particular to a UV coating construction process. Background technique [0002] At present, the solid-color UV decorative panels on the market generally use PU and PE paint as the base color, and the surface is sprayed with UV varnish and molded, especially the UV flash silver series panels. At present, PU flash silver spraying is generally used as the primer. Since PU and PE paints contain a large amount of thinner components, a large amount of harmful substances will volatilize during the production and decoration process, which will seriously affect the health of the body, and the production cycle is long, prone to bursting, Problems such as delamination of paint, no frost resistance and easy orange peel on the paint surface. Moreover, the existing technology often makes it difficult for the paint to adhere to the base material. It is urgent to invent a new construction method, so that after...

Problems solved by technology

At present, PU flash silver spraying is generally used as the primer. Since PU and PE paints contain a large amount of thinner components, a large amount of harmful substances will volatilize during the production and decoration process, which will seriously affect the health of the body, and the production cycle is long, prone to bursts, Problems such as paint layering, no frost resistance and easy orange peel on the paint surface

Moreover, the existing technology often makes it difficult for the paint to adhere to the base material. It is urgent to invent a new construction method so that it will not crack at low or high temperatures after painting and has good adhesion.
