Odorless staining-resistant anti-yellowing UV coated matt finish paint coating, and preparation method and construction technology thereof

Abstract

The invention discloses an odorless staining-resistant anti-yellowing UV coated matt finish paint coating, and a preparation method and a construction technology thereof. The coating comprise the following components in percentage by weight: 15 to 20% of organic silicone modified epoxy acrylate, 20 to 30% of aliphatic polyurethane acrylic resin, 35 to 41% of functional monomers, 4 to 5% of photoinitiators, 1 to 10% of extinction powder, and 4 to 5% of feeling agents. The coating has the advantages of convenient construction, and fast levelling and curing. The solid content is close to 100%, the utilization rate of the coating is close to 100%, and the emission of hazardous substances is close to zero, so that the stringent environmental requirements are satisfied, the operator health is effectively protected, and emissions are reduced.

Description

technical field [0001] The invention relates to a UV wood coating, in particular to a UV film-coated matte finish coating with clean odor, stain resistance, yellowing resistance, and a preparation method and construction process thereof. Background technique [0002] At present, the commonly used production process of preparing flat transparent matte decorative panels by photocuring coating is to apply the coating on the surface of the substrate by means of curtain coating, roller coating or spraying, and then undergo infrared self-leveling treatment, and then photocure. Curing molding, this kind of coating construction process, on the one hand, has the risk of dust polluting the surface of the coating film, on the other hand, due to oxygen inhibition, the surface of the UV coating is not completely cured, resulting in bad smell and a decline in scratch resistance. UV roller coating film coating technology can effectively solve the problem of poor surface drying and curing o...

Problems solved by technology

[0002] At present, the commonly used production process of preparing flat transparent matte decorative panels by photocuring coating is to apply the coating on the surface of the substrate by means of curtain coating, roller coating or spraying, and then undergo infrared self-leveling treatment, and then photocure. Curing molding, this kind of coating construction process, on the one hand, has the risk of dust polluting the surface of the coating film, on the other hand, due to oxygen inhibition, the surface of the UV coating is not completely cured, resulting in bad smell and a decline in scratch resistance. UV roller coating film coating technology can effectively solve the problem of poor surface drying and curing of UV coatings caused by oxygen inhibition. Because it is a fully enclosed construction operation, the roller coating film coating process can also obtain UV coatings without coating film defects. High hardness protective coating, but there are few UV coating coatings in the market at present, and the UV matte coatings on the market currently have odor before and after photocuring, and there are also poor yellowing resistance, poor pollution resistance and bad hand feeling. Poor scratch resistance and other characteristics, it is still blank in terms of deodorization and pollution resistance in UV lamination matte topcoat
