[0002] Most of the anti-counterfeiting inks used in the market today are solvent-based inks, which are composed of organic solvents (such as toluene, xylene, cyclohexanone, anti-white water, etc.), EVA resin, fillers, pigments, additives, etc. They are all It is a flammable and explosive toxic chemical. During the printing process, the organic solvent volatilizes into the atmosphere, thereby polluting the environment and endangering human health.

Abstract
The invention discloses an environment-friendly anti-counterfeiting ink and a preparation method thereof. The ink is composed of pure water, resin, propylene glycol, water-based film-forming plasticizer, pigments and fillers, auxiliary agents, water-based gold powder and other components. The present invention uses water-based polyurethane resin as the binder, which has very good flexibility. The resin has a strong ability to disperse and wrap pigments, is not easy to form skins, and has good resolubility and reduction, thereby solving the problem of easy blockage of screen plates during ink printing. In addition, water-based film-forming plasticizer can be added to change the glass transition temperature and film-forming temperature of the resin, and the weather resistance of the ink can be adjusted according to different climates. The selection of two different thickeners can make the thickened ink in a long-term stable viscosity range, which has a significant effect on storage stability. The anti-counterfeiting ink prepared by the invention has the advantages of environmental protection, safety, low odor, good film-forming covering performance, wear resistance and easy scratching, and will not become difficult to scratch off with prolonged storage time after printing.
Description
technical field [0001] The invention relates to the field of inks, in particular to an environment-friendly anti-counterfeiting ink and a preparation method thereof. Background technique [0002] Most of the anti-counterfeiting inks used in the market today are solvent-based inks, which are composed of organic solvents (such as toluene, xylene, cyclohexanone, anti-white water, etc.), EVA resin, fillers, pigments, additives, etc. They are all It is a flammable and explosive toxic chemical. During the printing process, the organic solvent volatilizes into the atmosphere, thereby polluting the environment and endangering human health. Therefore, the application of environmentally friendly water-based anti-counterfeiting inks in scratch card printing is an inevitable development trend in the future. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-counterfeit ink with environmental protection and excellent performance. The te...
