Abstract

The invention discloses an ultraviolet photocuring water-based ink. The ink is composed of the following raw materials by mass: 15% to 20% of an ultraviolet photocuring precursor, 15% to 20% of a prepolymer, 40% to 45% of a solvent, 1% to 3% of a photoinitiator, 15% of pigment and 5% of an additive, wherein the total mass percentage of the above-mentioned components is 100%. The invention also discloses a preparation method for the above-mentioned water-based ink. According to the invention, acrylic acid and trifluorobutyric acid are used to react with a glycidyl acrylate oligomer at room temperature under the catalysis of triethanolamine so as to obtain a polyenoid funcational group oligomer of a modified (methyl) glycidyl acrylate oligomer, and the obtained polyenoid funcational group oligomer used as the ultraviolet photocuring precursor greatly saves production cost of the ultraviolet photocuring water-based ink; meanwhile, due to low surface energy of trifluorobutyrate in the ultraviolet photocuring precursor, the image area of a printing product printed by using the ultraviolet photocuring ink in the invention has the characteristics of hydrophobic property, acid and alkali resistant properties, water-washing resistance, etc.; and application scope of the ultraviolet photocuring ink is wider.

Description

technical field [0001] The invention belongs to the technical field of printing and reproduction, and relates to a UV light-curable water-based ink, and also relates to a preparation method of the above-mentioned UV light-curable water-based ink. Background technique [0002] UV ink is a kind of ink that uses ultraviolet light of different wavelengths and energies under ultraviolet radiation to polymerize the curing precursor in the ink binder into a polymer, and finally forms a film and dries it. Its main component is polymerization Prepolymers, photosensitive curing precursors, photoinitiators, and auxiliary components are coloring pigments, fillers, additives (leveling agents, dispersants), etc. UV ink has the advantages of strong color matching ability, good wear resistance, scratch resistance, fast curing speed, good gloss, etc., and does not contain volatile organic solvents, which is in line with the general trend of green printing today. [0003] At present, most of...
