Problems solved by technology

Among them, the paint used for the gold coating is usually solvent-based or water-based paint. The disadvantage is that there are a large amount of volatile organic solvents in the production process of gold cardboard, which has a heavy smell, which is not good for the health of machine operators, and does not meet the national environmental protection requirements.

Abstract

The invention relates to an environment-friendly electron beam cured gold surface coating used for an aluminized paperboard and a preparation method thereof. The painting is composed of the following components by mass part: 50-80 of a liquid coating composition being capable of being cured by the electron beam, 5-30 of yellow pigment slurry, 1-10 of red pigment slurry, and 0.5-3.0 of an auxiliary agent. The preparation method comprises preparing the red pigment slurry and the yellow pigment slurry through mixing, dispersing, grinding, etc., adding the red pigment slurry and the yellow pigment slurry into the liquid coating composition being capable of being cured by the electron beam in a certain proportion, uniformly stirring, adding the auxiliary agent, dispersing in a high speed for 1-2 hours, and filtering the mixture under a temperature of 40-60 DEG C to obtain the electron beam cured gold surface coating used for the aluminized paperboard. The method provided by the invention is safe during a production process, high in efficiency, low in energy consumption, and free of emission and pollution; and the coating is high in transparency and fullness, and compared with traditional coating materials, is superior in adhesion fastness, spalling resistance, solvent resistance, heat resistance, scratch resistance and printability.

Description

[0001] technical field [0002] The invention relates to an electron-beam-cured golden topcoat for environment-friendly aluminum-plated cardboard and a preparation method thereof, belonging to the technical field of radiation-cured coatings. Background technique [0003] Vacuum aluminum-coated paper has become a new type of environmentally friendly material because of its good barrier properties to water and air, its minimal consumption of metal material aluminum, and its degradable and recyclable properties. It is widely used in tobacco, wine, sugar, etc. , tea, food, medicine and gift boxes. In order to satisfy consumers' visual effect and aesthetic feeling, high-end packaging boxes are mostly made of gold cardboard materials. [0004] At present, the domestic gold cardboard for cigarette packs is produced by the transfer method. The process is as follows: firstly, the solvent-based transfer coating is coated on the PET film, and the aluminum-coated layer is formed by th...
