Abstract
The invention discloses a water-based environment-friendly multi-purpose ink which is prepared from the following raw materials in parts by weight: 25-40 parts of modified acrylic resin, 15-25 parts of a pH regulator, 15-30 parts of a water-based pigment, 8-15 parts of a solubilizing assistant, 1-3 parts of phosphate ester, 0.1-0.4 part of silicone oil and 10-25 parts of deionized water. The nano-silica-modified water-based acrylic resin is adopted; meanwhile, the viscosity and pH of the water-based environment-friendly multi-purpose ink are controlled; multi-purpose printing of flexographic printing and gravure can be realized; the inventory and the residual ink are reduced; the printing chromaticiy, the glossiness, the abrasion performance and the weather resistance are improved. In addition, the water-based environment-friendly multi-purpose ink is simple in process, and low in cost; VOC emission is further reduced; meanwhile, no toxic and harmful substances are generated in the printing process; and the water-based environment-friendly multi-purpose ink is healthy and environment-friendly.
Description
technical field [0001] The invention relates to the technical field of water-based ink, in particular to a water-based environmentally friendly multi-purpose ink common to flexo printing and gravure printing. Background technique [0002] Water-based ink, referred to as ink, is mainly composed of colorants, binders, auxiliary agents and other components. The linking material is composed of water, resin, amine compounds and other organic solvents. Water-based ink has extremely low VOC content and hardly pollutes the environment. It is especially suitable for products with strict packaging requirements such as children's toys, medicines, food, and beverages. At present, the water-based inks on the market have disadvantages such as high cost, low gloss, poor water resistance, and poor wear resistance, and the inks used in flexo printing and gravure printing are usually used separately, which has poor versatility and will produce more residual ink. A large amount of inventory ...
