Abstract

The invention relates to a single-coated transfer aluminium-plated coating, a preparation method and an application thereof, wherein, the coating takes the following components with the contents (weight percent) as raw materials: 0 to 16 weight percent cellulose resin; 0 to 6 weight percent vinyl chloride-vinyl acetate resin; 4 to 20 weight percent polyacrylate resin; 0 to 1 weight percent auxiliary agent and 70 to 87 weight percent solvent. Compared with the prior art, the invention has the following advantages: (1) the single-channel coating is adopted, compared with two times of coating, the process is simple, the production efficiency is high, the energy consumption is less, the emission is less, the coating amount is less and the cost is low; (2) the product has good technological adaptability and is applicable to the different technological conditions of different manufacturers; (3) a coating layer has excellent comprehensive performance, great peeling performance, good adhesion with aluminium, wear resistance, temperature resistance, solvent resistance, good flexibility, high surface luminance brightness and good adaptability with ink printing; and (4) the coating and the coating layer have no triphenyl or other solvents which are prohibited by the industry, thereby being safe and environment-friendly.

Description

technical field [0001] The invention relates to a transfer aluminized paint, in particular to a single-coat transfer aluminized paint and a preparation method and application thereof. Background technique [0002] At present, the gold and silver cardboard used in the packaging boxes of tobacco, wine, food, daily necessities, etc. is mainly produced by the composite method, that is, the aluminum foil or aluminized film is directly composited with the paper. The aluminum foil and plastic film in the product cannot be degraded and recycled, resulting in Environmental pollution and massive waste of resources, in order to protect the environment and save resources, the transfer process and the direct plating process have begun to appear. [0003] The transfer process is to coat the transfer aluminized coating on polyester film or other films, dry it to form a film, and then coat it with aluminum, then apply compound glue to combine the aluminized film with paper, and finally peel...
