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 sol

[0036] Table 1

[0037]Among them, the silicone-modified epoxy acrylic resin used in the present invention has the characteristics of weather resistance, heat resistance, abrasion resistance, and good pollution resistance, and can endow the coating film with good mechanical properties and simultaneously have yellowing and anti-fouling properties. Aliphatic urethane acrylate used in the present invention is anti-yellowing aliphatic urethane acrylate containing 4 functional groups, which has good toughness and yellowing resistance. Compared with epoxy acrylic resin, polyurethane acrylic resin is easier to use in matte system. Delustering, so the present invention uses polyurethane acrylic resin as the main resin and epoxy resin as a supplement. The monomers used in the present invention are all benzene-free reactive monomers, so as to ensure that benzene vola...

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...
