A kind of reflective anti-counterfeiting ink and its preparation method and application

Abstract

The invention discloses a reflective anti-counterfeit ink and its preparation method and application. The reflective anti-counterfeit ink comprises the following components in weight percentage: 6-18% of glass microbeads, 36-60% of water-based polyurethane, 6-10% of pure water, and no Water ethanol 10-40%, dispersant 1-5%, defoamer 2-3%, anti-sedimentation agent 1-3%; reflective anti-counterfeiting ink is obtained after weighing, preparing solvent, first stirring, and second stirring; The reflective anti-counterfeiting ink prepared by the invention can be applied to screen printing. In the present invention, glass microspheres are added to the reflective anti-counterfeiting ink, and the glass microspheres have a high refractive index physical structure, so that the reflective anti-counterfeiting ink has the characteristic of retroreflection, thereby achieving the effect of anti-counterfeiting. When in use, the printed graphics and texts can be identified through the flash shooting function of the mobile phone. The identification method is convenient, fast and interactive.
