Abstract

The invention relates to a single-coating aluminum plating transfer coating suitable for gravure and a preparation method thereof. The coating comprises the following components in percentage by weight: 0 to 6 percent of vinyl acetate chlorate resin, 8 to 25 percent of acrylic resin, 0 to 12 percent of cellulose resin, 0 to 1 percent of auxiliary agent, and 70 to 85 percent of solvent. The preparation method comprises the following steps of: preparing materials, and then adding the solvent, the resin components and the auxiliary agent into a reaction kettle; controlling the stirring speed, the reaction temperature, the solid content and the viscosity; and performing cooling and filtering to obtain a final product. Compared with the prior art, the single-coating aluminum plating transfer coating has a simple production process, a high production efficiency, less energy consumption and a low cost; an printing ink has good levelling on the surface of a coating layer, has no lifting, and is difficult to generate alligator cracks and expose colors; and a piece of aluminized paper has good surface flatness, high metallic luster, good smoothness and good abrasion resistance, and contains no industrial forbidden solvents such as a triphen type solvent and the like.

Description

technical field [0001] The invention relates to a single-coat aluminum-plating transfer paint and a preparation method thereof, in particular to a single-coat aluminum-plating transfer paint suitable for gravure printing and a preparation method thereof. Background technique [0002] In recent years, in response to the requirements of environmental protection and resource conservation, most of the gold and silver paperboards used in the paper packaging fields of tobacco, alcohol, food, and daily necessities have changed from the original composite method to the transfer method. The transfer method is to coat the aluminized transfer coating on the polyester film or polypropylene film, dry it to form a film, and then aluminize it, then apply a compound glue to combine the aluminized film with the paper, and finally peel off the film to become an aluminized transfer coating. Paper. [0003] The key role in the transfer process is the aluminized transfer coating. The aluminized...
