Problems solved by technology

[0003] The laser transfer aluminized coating used in the existing vacuum aluminized paper packaging products has major shortcomings in the seamless molding process
At present, the existing laser transfer coatings on the market have problems such as poor laser brightness, difficult to eliminate seam lines, large color difference, obvious transition area and narrow transition area when molding without seam.
Therefore, the development of the laser transfer aluminum coating industry is greatly limited.

Abstract

The invention relates to a radar aluminum plating transfer coating suitable for a seamless molding process and a preparation method thereof. The coating comprises the following components in percentage by weight: 0 to 4 percent of amino resin, 0 to 15 percent of cellulose ester resin, 3 to 28 percent of polyacrylate resin, 0 to 10 percent of nitro-cotton resin, 0 to 6 percent of vinyl acetate chlorate resin, 0 to 2.8 percent of additive, and 70 to 85 percent of solvent. The preparation method comprises the following steps of: adding the solvent and the resin components into a reaction kettle; stirring the mixture and then adding the additive into the mixture; and after adjusting the solid content and the viscosity, continuously stirring, cooling and filtering the mixture to obtain a product. Compared with the prior art, the radar aluminum plating transfer coating has the advantages of high production efficiency, low energy consumption, good process adaptability, good molding effect, easy elimination of seams, easy control of production, high smoothness degree, temperature resistance, good flexibility and the like.

Description

technical field [0001] The invention relates to a laser aluminized transfer paint and a preparation method, in particular to a laser aluminized transfer paint suitable for a seamless molding process and a preparation method. Background technique [0002] Laser transfer aluminized paper is mainly composed of base paper, aluminum layer and transfer coating with laser effect, because of its high gloss, good smoothness, high firmness of aluminum sprayed layer, good flexibility, good printing adaptability and mechanical Processing performance, environmental protection and beauty, and strong anti-counterfeiting effect, are widely used in new packaging materials for tobacco and alcohol, food, cosmetics, tea, gifts, etc. [0003] The laser transfer aluminized coating used in the existing vacuum aluminized paper packaging products has relatively large disadvantages in the seamless molding process. At present, the existing laser transfer coatings on the market have problems such as p...
