Problems solved by technology

[0003] However, there is an obvious defect in the existing ultraviolet curable ink (UV ink) used for UV silk screen wrinkle process, that is, after the ink printing layer is formed on the cardboard or white cardboard with light background color, the printed matter will not When placed in the sun under natural light, the ink printing layer will completely turn yellow in a short period of time (such as 1 hour), and the yellowing resistance is extremely poor (see Table 1)
Although some UV-curable inks have better overcome the problem of poor yellowing resistance of the ink printing layer, the ink printing layer is relatively brittle, prone to bursting when bent, and has poor folding resistance (see Table 2)
In addition, most UV-curable inks often have the problem of excessive organic volatiles

Abstract

Ultraviolet curing ink comprises the following components in weight proportion: 24-35% of polyurethane acrylate, 14-25% of epoxy acrylate, 15-25% of tripropylene glycol diacrylate, 15-25% of 1,1,1-trimethylol propane triacrylate, 0.5-2.5% of 1,1'-(methylenedi-4,1-phenylene)bis[2-hydroxyl-2-methyl-1-acetone],0.5-1.5% of Oligo[2-hydroxy-2-methyl-1-[4-(1-methylvinyl)phenyl]propanone], 0.1-1% of polydimethylsiloxane, 0.1-1% of polyether modified polysiloxane and 1-5% of polyethylene wax. The invention further provides the preparation method of the ultraviolet curing ink. According to the ultraviolet curing ink, an ink printing layer with a wrinkle effect is formed after the ultraviolet curing ink is cured after printing, and the ink printing layer has good anti-yellowing performance and good folding endurance.

Description

technical field [0001] The invention relates to an ink composition, in particular to an ultraviolet light curing ink and a preparation method thereof. Background technique [0002] The UV silk screen wrinkle process is a printing process commonly used in the printing industry at present. This process is highly decorative and can make the printed matter have a good metallic feel and strong visual impact. It can attract consumers' attention and increase the additional value of the printed matter. value. [0003] However, there is an obvious defect in the existing ultraviolet curable ink (UV ink) used for UV silk screen wrinkle process, that is, after the ink printing layer is formed on the cardboard or white cardboard with light background color, the printed matter will not Placed in the sun under natural light, the ink printing layer will completely turn yellow in a short period of time (such as 1 hour), and the yellowing resistance is extremely poor (see Table 1). Although...
