Abstract

The invention discloses low-reflection printing ink and a preparation method thereof. The low-reflection printing ink is prepared by adding matting powder, carbon black and modified activated carbon powder into a resin material. Microcosmic roughness is formed on the surface of the coating after ink curing, specular reflection is reduced, in addition, the light absorption capacity of the coating is further enhanced through the modified activated carbon powder, and the modified activated carbon powder and the light absorption capacity of carbon black can well achieve a synergistic effect to jointly reduce light reflection of the coating. The prepared low-reflection ink has the advantages of being good in weather resistance, low in reflectivity, excellent in construction performance and the like.
