Embodiment 1

[0043] A kind of UV anti-scratch matte clear topcoat, by weight percentage: YTM6318 5%, YTM5607 5%, tripropylene glycol diacrylate 5%, trimethylolpropane triacrylate 6%, 1,6-hexane Glycol Diacrylate 6%, Ethoxylated Trimethylolpropane Triacrylate 7%, Nitrocellulose 23%, Cellulose Acetate Butyrate 23%, Fumed Silica 8%, 1-Hydroxy-Cyclohexyl -Phenylphenone 2%, 2-Hydroxy-2-methyl-1-phenyl-1-propanone 2%, (2,4,6-trimethylbenzoyl)diphenylphosphine oxide 2%, Butyl acetate 1%, ethanol 1%, ethyl acetate 2%, isopropanol 1.7%, BYK141 0.1%, DEGO450 0.2%. According to the paint making method commonly used by those skilled in the art, the above materials are made into UV matte clear topcoat, and the equipment is automatically sprayed on the substrate, which can greatly improve the production efficiency. Excellent leveling property can be obtained after curing, which can achieve the surface effect of PU paint, and its hardness and scratch resistance are better than PU paint.

Embodiment 2

[0045] A kind of UV anti-scratch matte clear topcoat, by weight percentage: YTM6318 2%, YTM5607 3%, tripropylene glycol diacrylate 6%, trimethylolpropane triacrylate 7%, 1,6-hexane Glycol Diacrylate 6%, Ethoxylated Trimethylolpropane Triacrylate 8%, Nitrocellulose 23%, Cellulose Acetate Butyrate 23%, Fumed Silica 7%, 1-Hydroxy-Cyclohexyl -Phenylphenone 3%, 2-Hydroxy-2-methyl-1-phenyl-1-propanone 2%, (2,4,6-trimethylbenzoyl)diphenylphosphine oxide 1%, Butyl acetate 1.7%, ethanol 2%, ethyl acetate 2%, isopropanol 3%, BYK141 0.1%, BYK-333 0.2%. According to the paint making method commonly used by those skilled in the art, the above materials are made into UV matte clear topcoat, and the equipment is automatically sprayed on the substrate, which can greatly improve the production efficiency. Excellent leveling property can be obtained after curing, which can achieve the surface effect of PU paint, and its hardness and scratch resistance are better than PU paint.

Abstract

The invention relates to a coating in the chemical engineering field, in particular to UV (ultraviolet) anti-scratch matte finishing paint. The UV matte finishing paint comprises components in percentage by weight as follows: 5%-13% of polyurethane acrylate, 15%-30% of a monomer, 15%-25% of nitrocotton, 15%-25% of cellulose acetate butyrate, 1%-10% of fumed silica, 3%-7% of a photoinitiator, 0.1%-0.5% of an auxiliary and 5%-10% of a solvent, wherein polyurethane acrylate is a mixture of modified aliphatic polyurethane acrylate and modified aromatic polyurethane acrylate. The UV matte finishing paint can be automatically sprayed on a substrate by equipment, and the production efficiency can be improved greatly; and the excellent levelling property can be obtained after curing of the paint, the UV matte finishing paint has the surface effect of PU (polyurethane) paint, and the hardness and the anti-scratch property of the UV matte finishing paint are superior to those of PU paint.

Description

technical field [0001] The invention relates to a coating in the field of chemical industry, in particular to a UV scratch-resistant matte varnish. 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. [0003] C...
