Problems solved by technology

However, the leveling and gloss uniformity of general UV paints cannot meet the market requirements when such large topcoats are sprayed. The traditional method is to use UV primers and then spray PU topcoats.
This results in more processes, longer working hours, and the use of PU paint, which releases a large amount of organic solvents to pollute the atmosphere. The overall efficiency and benefits are not high, which reduces the overall efficiency of coating.

Embodiment 1

[0052] A UV matt clear finish paint for vacuum spraying, the components and their parts by weight are as follows: 28 parts of epoxy acrylate (Changrunfa Yatumei YTM2100), 42.4 parts of tripropylene glycol diacrylate, 18 parts of isooctyl acrylate, 6 parts of filler, 0.2 parts of fumed silica, 1 part of 1-hydroxy-cyclohexyl-phenyl ketone (184), 2-hydroxy-2-methyl-1-phenyl - 2 parts of 1-acetone (1173), 1 part of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide (TPO), 0.5 part of defoamer, 0.5 part of leveling agent, wetting and dispersing 0.4 parts of the agent. According to the paint making method commonly used by those skilled in the art, the above materials were made into UV vacuum spray matte clear topcoat, which was automatically sprayed on the substrate with vacuum spray equipment, and the performance test was carried out. The results are shown in Table 1.

Embodiment 2

[0054] A UV matte clear finish paint for vacuum spraying, the components and their parts by weight are as follows: 29 parts of epoxy acrylate (Changrunfa Yatumei YTM2100), 43.4 parts of tripropylene glycol diacrylate, 15 parts of isooctyl acrylate, 7 parts of filler, 0.2 parts of fumed silica, 1 part of 1-hydroxy-cyclohexyl-phenyl ketone (184), 2-hydroxy-2-methyl-1-phenyl - 2 parts of 1-acetone (1173), 1 part of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide (TPO), 0.5 part of defoamer, 0.5 part of leveling agent, wetting and dispersing 0.4 parts of the agent. According to the paint-making method commonly used by those skilled in the art, the above-mentioned materials were made into a UV matte clear topcoat, which was automatically sprayed on the substrate with a vacuum spraying equipment, and the performance test was carried out. The results are shown in Table 1.

Embodiment 3

[0056] A UV matt clear finish paint for vacuum spraying, the components and their parts by weight are as follows: 30 parts of epoxy acrylate (Changrunfa Yatumei YTM2100), 44.4 parts of tripropylene glycol diacrylate, 12 parts of isooctyl acrylate, 8 parts of filler, 0.2 parts of fumed silica, 1 part of 1-hydroxy-cyclohexyl-phenyl ketone (184), 2-hydroxy-2-methyl-1-phenyl - 2 parts of 1-acetone (1173), 1 part of (2,4,6-trimethylbenzoyl) diphenylphosphine oxide (TPO), 0.5 part of defoamer, 0.5 part of leveling agent, wetting and dispersing 0.4 parts of the agent. According to the paint-making method commonly used by those skilled in the art, the above-mentioned materials were made into a UV matte clear topcoat, which was automatically sprayed on the substrate with a vacuum spraying equipment, and the performance test was carried out. The results are shown in Table 1.

Abstract

The invention discloses a UV matte top-coat paint for vacuum spraying. The UV matte top-coat paint is prepared from the following components in parts by weight: 20-35 parts of epoxy acrylate, 35-60 parts of a monomer, 5-10 parts of a filler, 0.1-0.5 part of gas-phase silica, 3-6 parts of a photoinitiator, 0.4-0.6 part of a flow agent, 0.3-0.5 part of a defoamer and 0.2-0.5 part of a wetting dispersant, wherein the epoxy acrylate is modified epoxy acrylate with a Meiyatu code number of Changrunfa to be YTM2100. The UV matte top-coat paint is automatically sprayed on a substrate by using vacuum spraying equipment, so that the production efficiency can be greatly improved; by virtue or reasonable matching of the raw material, as very good levelling property can be obtained after the UV matte top-coat paint is cured, the surface effect of a PU paint can be achieved, and the rigidity and the scraping resistance are superior to those of the PU paint.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a UV matte varnish for vacuum spraying. Background technique [0002] UV paint is a light-curing paint. It is currently a widely used furniture paint. Its main features are: after strong ultraviolet light curing treatment, the color is stable and always new. Therefore, it is widely used in office furniture and other aspects, and has been used in large-area office furniture in recent years. However, when the general UV paint is sprayed with such a large topcoat, the leveling and gloss uniformity cannot meet the market requirements. The traditional method is to use a UV primer and then spray a PU topcoat. This results in more processes, longer working hours, and the use of PU paint, which releases a large amount of organic solvents to pollute the atmosphere. The overall efficiency and benefits are not high, which reduces the overall efficiency of painting. Contents of the invent...
