Abstract

A disclosed color-adjustable environment-friendly water-based ink is prepared from the following raw materials in parts by weight: 20-30 parts of a binder, 5-10 parts of a combined solvent, 5-10 partsof pigment, 2-6 parts of sodium alcohol ether sulphate, 20-40 parts of deionized water, 3-6 parts of a wear-resistant slipping agent, 0.1-0.5 part of an antifoaming agent, 0.2-0.4 part of a dispersing agent, 0.1-0.3 part of a leveling agent and 0.1-0.3 part of a buffering agent. When the wear-resistant slipping agent is added into water-based ink, the wear resistance, glossiness, aging resistanceand waterproofness of the ink can be improved; by combining the characteristics of epoxy resin, modified siloxane and acrylic acid, the ink binder with high temperature resistance, good adhesive force and high glossiness is prepared; by adding an emulsifier, dispersing agent and other assistants, the water-based ink has the advantages of high viscosity, uniform component distribution and stable state, and has excellent wear resistance, aging resistance, water resistance and acid / alkali corrosion resistance in the use process.

Description

technical field [0001] The invention belongs to the technical field of ink preparation, and in particular relates to a color-tunable environmental-friendly water-based ink and a preparation method thereof. Background technique [0002] Water-based ink is mainly made of water as the main solvent through scientific processing. Compared with other inks, water-based ink does not contain volatile organic solvents, so it has no adverse effects on the health of printing operators during the printing process. There is no pollution to the environment, and no pollution to the printed matter itself. Because the water-based ink is non-flammable, it can also eliminate the hidden dangers of flammability and explosion in the printing workshop, which is conducive to safe production. [0003] Water-based ink is made of water-soluble resin, high-grade pigments, solvents and additives through scientific compound processing and grinding. Water-soluble resin mainly plays the role of binder in th...
