Abstract

The invention discloses a water-based ultraviolet-curing printing ink and a preparation method thereof. The printing ink comprises the following raw materials by weight: 20-30 parts of epoxy acrylic resin, 10-15 parts of polyurethane acrylic resin, 5-10 parts of polyester acrylic resin, 4-6 parts of diphenyl ketone, 2-4 parts of 2,2-diethoxyacetophenone, 10-15 parts of pigments, 2-3 parts of isopropanolamine, 8-12 parts of pentaerythritol triacrylate, 15-20 parts of diacrylic acid-1,6-hexylene glycol ester, 3-5 parts of propylene glycol ethyl ether, 1-2 parts of a fluorocarbon surfactant FC-4430, 0.5-1 part of a defoamer BYK-019, 3-5 parts of a compound filler and 20-25 parts of de-ionized water. The water-based printing ink is excellent in performance, can be instantly cured after being irradiated by ultraviolet rays, is free from evaporation of a petroleum solvent, cannot pollute the environmental and is safe to use; the printing ink can be still kept stable in performance and cannot be mildewed after being stored in the printing process and even an ink fountain for a long term; a printed product is good in color stability and high in brightness, and an ink layer is higher in friction resistance, chemical resistance and adhesiveness; the printing ink has a wide application prospect.

Description

technical field [0001] The invention relates to an ink, in particular to a water-based ultraviolet light curing ink and a preparation method thereof. Background technique [0002] Ultraviolet curing (UV) ink refers to the ink that uses ultraviolet light of different wavelengths and energies to form a film and dry the ink under ultraviolet radiation. During the manufacturing, printing and drying process of solvent-based inks, due to the large amount of volatilization of solvents, it not only pollutes the environment, but also endangers the health of operators. There are hidden dangers in safety, and its use is increasingly restricted. Curing ink has become an important development trend of ink. Water-based UV-curable inks have almost zero pollutant emissions. In addition to being solvent-free, UV inks also have the advantages of not being easy to paste, clear dots, bright and bright ink colors, excellent chemical resistance, and low consumption. However, the current domesti...
