Abstract

The invention provides an acrylic copolymer emulsion, the acrylic acid copolymer emulsion is prepared from methyl methacrylate, n-butyl acrylate, 2-ethylhexyl acrylate, acrylic acid and hydroxyethyl methylacrylate monomers through copolymerization, and the invention further provides water-based ink based on the acrylic acid copolymer emulsion. The invention also provides a preparation method of the water-based ink. The water-based ink prepared by the method has the advantages of low odor, low VOC (Volatile Organic Compounds), boiling resistance, alcohol scrubbing resistance, strong acid resistance, friction resistance, hand perspiration resistance and excellent adhesion to PMMA (Polymethyl Methacrylate).

Description

technical field [0001] The invention relates to the field of water-based ink, in particular to an acrylic copolymer emulsion, water-based ink and a preparation method thereof. Background technique [0002] Inks are divided into solvent-based inks and water-based inks. Solvent-based inks have the characteristics of strong odor and high VOC, which are not good for human health and the environment. Therefore, water-based inks have become a market trend. The binders of water-based inks are mainly water-based resins, including glue. At present, due to the properties of water-based inks, some of them can be applied to plastics with strong polarity, such as PC and ABS. However, the adhesion to PMMA plastics is poor, and the main application In paper printing, some of them can be applied to the spraying of metal materials. In addition, water-based inks also have the disadvantages of poor water boiling resistance, poor alcohol scrubbing resistance, poor acid resistance, poor friction...
