Abstract

The invention discloses a laser alumite color layer coating and a preparation method thereof. The laser alumite color layer coating comprises dispersion solvent, an acrylics monomer, rosin resin, toner and cellulose nitrate. The preparation method comprises the steps of dissolving the acrylics monomer, rosin resin, toner and cellulose nitrate into the dispersion solvent, and stirring the mixture. In this way, the laser alumite color layer coating prepared through the method is good in dispersion performance and good in coating and leveling effect, after the coating is cured and subjected to secondary mold pressing, it can be guaranteed that the optical grating effect of a mold pressing plate is shifted to the surface of a color layer completely, and the color layer cannot penetrate through a release layer, so that completeness of all functional layers of laser alumite is guaranteed, and meanwhile the peeling effect in the gold stamping process of a laser alumite finished product is guaranteed.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-temperature, high-pressure molded laser anodized aluminum color coating and a preparation method thereof. Background technique [0002] Anodized aluminum hot stamping products have exquisite appearance, full and round color of hot stamping pattern, strong metal texture, excellent wear resistance and corrosion resistance, so they are widely used in the field of surface decoration. With the development of the times, people put forward higher requirements for anodized aluminum and its bronzing products, not only requiring that the slitting and hot stamping of anodized aluminum itself can be adapted to the bronzing on the surface of various materials, but also requiring its bronzing pattern to carry more information. To meet people's different aesthetic needs. [0003] As a relatively new type of anodized aluminum, laser anodized aluminum adopts molding technology t...
