Embodiment 1

[0021] A photo UV curing finish coating, by weight percentage: YTM2085 15%, YTM6318 8%, YTM5607 24%, TMPTA 20%, HDDA 10%, NPGDA 16%,, 1173 6%, BKY141 0.5%, DEGO450 0.5% According to the paint making method commonly used by those skilled in the art, the above materials are made into photo UV curing varnishes, sprayed on the substrate by spraying, and cured by UV lamps after leveling for 3 to 5 minutes to achieve excellent mirror effects. Very high fullness, good decoration and protection effect, can greatly improve product quality and production efficiency, friendly to the environment, can reduce the emission of organic solvents.

Embodiment 2

[0023] A photo UV curing finish coating, by weight percentage: YTM2085 25%, YTM6318 3%, YTM5607 17%, TPGDA 16%, TMPTA 30%, 184 2%, TPO 5%, BKY141 0.5%, BYK-333 1.5 %, according to the paint-making method commonly used by those skilled in the art, the above materials are made into photo UV curing varnishes, sprayed on the substrate by spraying, and cured by UV lamps after 3 to 5 minutes of leveling to achieve an excellent mirror surface Effect, extremely high fullness, good decoration and protection effect, can greatly improve product quality and production efficiency, is friendly to the environment, and can reduce the emission of organic solvents.

Embodiment 3

[0025] A photo UV curing finish coating, by weight percentage: YTM2085 15%, YTM6318 4%, YTM5607 13%, TPGDA 10%, TMPTA 12%, HDDA 8%, HEMA 17%, NPGDA 14%, 184 2%, 1173 2%, TPO 2%, BKY141 0.3%, DEGO450 0.7%, according to the paint making method commonly used by those skilled in the art, the above materials are made into photo UV curing finish coatings, sprayed on the substrate by spraying, leveling After 3~5 minutes, UV lamp curing can achieve excellent mirror effect, high fullness, good decoration and protection effect, can greatly improve product quality and production efficiency, is friendly to the environment, and can reduce the emission of organic solvents.

Abstract

The invention discloses an UV (ultraviolet) curing finishing coating for photos. The UV curing finishing coating for the photos comprises the following components in weight percentage: 30-57 percent of resin, 37-62 percent of monomers, 4-7 percent of photoinitiator and 0.7-2.0 percent of other addition agents, wherein the resin is a mixture of modified epoxy acrylate, modified aromatic polyurethane acrylate and modified aliphatic polyurethane acrylate. By adopting the UV curing finishing coating for the photos, no construction mark is present, excellent mirror surface effect can be achieved, the quality and production efficiency of products can be greatly improved and the discharge of organic solvents can be reduced, and the UV curing finishing coating has good adhesive force, high fullness, high brightness and very good decoration and protection effects and is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a photo UV curing varnish coating. Background technique [0002] UV paint is a light-curing coating. It is a widely used varnish at present. Its main features are: after strong ultraviolet light curing treatment, the paint film is stable, has strong solvent resistance, and is always new for a long time. Therefore, it is used in various varnish protection There are many applications on objects. However, ordinary UV varnish directly sprayed on the photo has poor adhesion, and cannot be thickly coated, and the fullness is not high, so the conventional method is to spray a solvent-based primer on the photo first, and then spray UV varnish coating. This results in more processes, volatilization of organic solvents, and longer working hours, which reduces the overall efficiency of coating. [0003] Contents of the invention [0004] The object of the present invention is to aim ...
