Abstract

The invention discloses water-based UV black ink with super-high solid content and a preparation method thereof. The black ink comprises the following components in percentage by weight: 20%-60% of high-functionality water-based polyurethane acrylate, 5%-8% of compound photoinitiator, 15%-35% of hydrophilic acrylate diluted body or prepolymer, 10%-25% of solvent and 5%-15% of nano-carbon black pigment. The light curing time of the water-based UV black colored paint of the invention is shorter than 5 seconds, the bottom layer can be completely cured, the comprehensive properties of adhesive force, hardness, toughness and the like are excellent, and the water-based UV black colored paint can be widely applied to the fields of ink, wood paint and the like; the solid content is as high as 80%;and the water-based UV black ink has short drying and curing time, simple construction technology and high production efficiency, can be diluted by water or ethanol or other nontoxic solvents for regulating the viscosity, is suitable for various production modes and production requirements, and is environment-friendly and nontoxic.

Description

technical field

[0001] The invention relates to an ultra-high solid content aqueous UV black ink and a preparation method of the black ink. Background technique

[0002] With the development of science and technology, traditional solvent-based inks have exposed many problems, such as emitting a large amount of VOC (volatile organic compounds) into the atmosphere, which poses a huge threat to the working environment, packaging contents and human health. Therefore, the development of "green inks" represented by water-based inks and radiation-curable inks is an important development trend of future inks.

[0003] Water-based UV ink is a new type of "green ink" emerging in recent years. It can combine the advantages of water-based ink and UV ink, and has received more and more attention. However, the current water-based UV inks still have the following disadvantages: (1) Water-based UV inks usually contain a large amount of water with low solid content. Due to the high surface ...
