Abstract

The invention discloses a water-based laser transfer coating for wine bottle glass baking paper, and a preparation method thereof. The coating is prepared by mixing the following components in percentage by mass: 10-30% of water-based acrylic resin, 25-40% of water-based polyurethane resin, 0-8% of cosolvent, 20-45% of deionized water, 0-0.4% of water-based defoaming agent, 0.1-0.4% of base material wetting agent, and 0-0.2% of pH value regulating agent. The water-based laser transfer coating for the wine bottle glass baking paper is an environment-friendly laser transfer coating which meets national VOC detection standard by taking the water-based resin and deionized water as main raw materials. In addition, the composite water-based resin endows a curing film with good temperature resistance, aluminum adherence, strippability, alcohol resistance and the like, thus meeting the index requirement of the wine bottle glass baking paper.

Description

technical field [0001] The invention relates to a water-based coating and a preparation method thereof, in particular to a water-based laser transfer coating for wine bottle glass decal paper and a preparation method thereof. Background technique [0002] The laser transfer process is to coat the transfer aluminized paint on the PET or BOPP base film, dry the film and vacuum aluminize it, then apply the composite glue, combine the aluminized film and paper, and finally peel off the film to become the transfer aluminized coating. paper process. Compared with the traditional composite process, it has the advantages of low cost, environmental protection, and beautiful appearance. In just a few years, the laser transfer process has developed rapidly in the international and domestic packaging markets, and is still in the stage of rapid growth. The laser transfer coating plays a key role in the laser transfer process, and its performance directly determines the temperature resi...
