Embodiment 1

[0038] Waterborne Aromatic Urethane Acrylate (A-1) 35%

[0039] Ethoxylated Trimethylolpropane Triacrylate 6%

[0040] Deionized water 55%

[0041] 4'-(2-Hydroxyethoxy)-2-hydroxy-2-methylpropiophenone 4%

[0042] After mixing the above-mentioned components in proportion, stir at 40-50°C for about 0.5 hours, filter with a 200-mesh filter cloth and pack, then the UV-curable leather or artificial leather water-based coating of the present invention is obtained. Spray the coating on artificial PU leather, level it at 50°C for 3 minutes, and measure its performance after being cured by ultraviolet light. The results are shown in Table 1.

Embodiment 2

[0044] Waterborne Aromatic Urethane Acrylate (A-1) 40%

[0045] Polyethylene Glycol Acrylate 5%

[0046] Deionized water 50%

[0047] 4'-(2-Hydroxyethoxy)-2-hydroxy-2-methylpropiophenone 5%

[0048] The sample preparation method is the same as in Example 1, and the properties of the coating film are shown in Table 1.

Embodiment 3

[0050] Waterborne Aliphatic Urethane Acrylate (A-2) 48%

[0051]Deionized water 45%

[0052] 4'-(2-Hydroxyethoxy)-2-hydroxy-2-methylpropiophenone 5%

[0053] 1-Hydroxy-1-cyclohexylbenzophenone 2%

[0054] The sample preparation method is the same as in Example 1, and the properties of the coating film are shown in Table 1.

Abstract

An ultraviolet solidified water paint for leather and artificial leather contains proportionally aqueous aliphatic or aromatic polyurethane acrylate, aquous acrylate, deionized water and optical trigger.

Description

technical field [0001] The invention belongs to the water-based photocurable paint in the field of chemical industry, in particular to an ultraviolet light-curable leather or artificial leather water-based paint used in industries such as leather or artificial leather processing. Background technique [0002] The traditional surface treatment of leather and artificial leather includes solvent-based one-component polyurethane and two-component polyurethane. The solid content is generally 30-40%, which causes great pollution to the environment. Leather treated with one-component polyurethane has simple construction and fast drying speed, but the coating film has poor solvent resistance, corrosion resistance and abrasion resistance; two-component polyurethane has better overall performance, but slow drying time and low production efficiency , The application of water-based polyurethane system to treat the surface of leather and artificial leather is a ne...
