Problems solved by technology

[0003] The existing anodized aluminum color layer paint is usually formed by mixing resin, toner and solvent. Due to the unreasonable selection of resin type and content, the formed anodized aluminum color layer does not perform well in the bronzing process, especially in the process of stamping. During the production of round stamping, it is very easy to produce black plate, paste plate, sticky plate, etc., as well as the phenomenon of unclean stamping peeling and incomplete stamping patterns, which greatly affect the production efficiency, production cost and product quality.

Abstract

The invention relates to alumite color layer coating, which is prepared from the following ingredients in parts by weight: 15 to 25 parts of acrylic resin, 3 to 5 parts of polyurethane resin, 1 to 3 parts of perchloro-ethylene resin, 0.5 to 1 part of silicon dioxide powder, 1 to 2 parts of cellulose nitrate, 15 to 25 parts of solvents, 0.1 to 0.5 part of anti-foaming agents and 0.1 to 0.5 parts ofleveling agents. The invention also provides a preparation method of the alumite color layer paint. The alumite color layer paint is uniformly coated onto the surface of an alumite release layer through coating equipment; after the high-temperature curing, an alumite color layer is obtained; the formed alumite color layer has good consistency and color phase fullness; phenomena of black template,burnt template, template adhesion and the like cannot easily occur in the gold stamping, particularly in the high-speed rotary gold stamping production process; the peeling is clean; the gold stamping patterns are complete.

Description

technical field [0001] The invention relates to a paint composition, in particular to an anodized aluminum color layer paint and a preparation method thereof. Background technique [0002] Anodized aluminum bronzing products are currently widely used in printed products because of their clear patterns, beautiful appearance, bright colors, wear resistance, weather resistance, unique metal texture, and strong bumpy touch. For example, bronzing on cigarette label printing The application of technology accounts for more than 85%. Bronzing on graphic design can play a finishing touch and highlight the design theme, especially for trademarks and registered names, the effect is more significant. And these effects all depend on the anodized aluminum color layer to show. Anodized aluminum color layer (also called anodized aluminum information layer) is formed by coating the anodized aluminum color layer paint evenly on the anodized aluminum release layer by a coating machine, and t...
