Problems solved by technology

Ammonia water is volatile and has a strong odor, which leads to the disadvantage of poor pH stability of the system
[0011] 3. Since the printing permeability of water-based ink and applicable base paper is better than other types of ink, which affects the color brightness of the ink, resulting in poor gloss of the ink, the above two patents do not solve the glossiness and bright colors of water-based ink degree problem

Abstract

The invention relates to a fluorescent water-based ink which comprises the following raw materials in part by weight: 15-20 parts of organic pigment, 1-2.5 parts of inorganic ultraluminescence pigment, 0.5-5 parts of dispersing agent, 0.1-1 part of foam killer, 10-30 parts of deionized water, 30-50 parts of self-crosslinking acrylic emulsion, 1-5 parts of film forming additive, 1-5 parts of thickening agent and 1-5 parts of cosolvent. According to the invention, the self-crosslinking acrylic ester emulsion, rather than water-soluble acrylate, is adopted to disperse the inorganic ultraluminescence pigment, so as to achieve uniform and stable dispersion of the inorganic ultraluminescence pigment in water-based ink; with the self-crosslinking reaction, the tinting strength and adhesive power of the water-based ink are improved; and the water-based ink has superior printability and superior glossiness.

Description

technical field [0001] The invention relates to an ink, in particular to a fluorescent water-based ink and a preparation method thereof. Background technique [0002] Water-based ink is referred to as ink for short, and flexographic water-based ink is also called liquid ink. It is mainly made of water-soluble resin, organic pigment, solvent and related additives through compound grinding. [0003] In the 1970s, due to the oil crisis, raw materials for inks were in short supply. At the same time, developed countries enacted legislation to control air quality, limit the emission of volatile organic compounds (VOC) into the atmosphere, and required strict packaging for food, beverages, and pharmaceuticals. The content of heavy metals and residual solvents in printed products are restricted. Ink R&D personnel from various countries continue to conduct in-depth research, and have produced the second-generation water-based ink with solution-type styrene-acrylic acid copolymer res...
