example 1

[0043] Reference attached figure 1 , a vacuum aluminized matte cardboard, comprising the bottom paper substrate 4, followed by a matte coating layer 3 and an aluminized layer 2, on which the aluminized layer 2 can be directly offset or gravure printed.

[0044] The above-mentioned production method of vacuum aluminized frosted cardboard comprises the following steps

[0045] (1) At first, make frosted paint mixture;

[0046] In a kind of water-containing acrylic emulsion, polyvinyl alcohol, carboxymethyl cellulose composition, the ball mill disperses a kind of nano-scale silicon oxide powder silicon oxide powder (frosting powder) to form a kind of coating mixture with frosting effect, It is an environmentally friendly water-based frosted coating. After curing, some of the particles are wrapped in organic molecules, and some parts are exposed on the surface of the coating, which increases light scattering and achieves a matting effect, thereby forming a matte layer with a fros...

example 2

[0057] (1) In a composition containing epoxy acrylate photosensitive resin, tripropylene glycol diacrylate, propoxylated trimethylolpropane triacrylate, monomaleimide resin, methylethanolamine, add a small amount Dispersant and leveling agent, uniformly disperse silicon oxide powder into the composition to form a UV-curable frosted coating.

[0058] The proportioning ratio of each component of the UV-curable frosted paint mixture is:

[0059] Epoxy acrylate photosensitive resin 30-50 parts

[0060] Tripropylene glycol diacrylate 10-30 parts

[0061] Propoxylated trimethylolpropane triacrylate 15-30 parts

[0062] 1-5 parts of monomaleimide resin

[0063] Methylethanolamine 0.2~1 part

[0064] Wax-modified silica powder 2-10 parts

[0065] Dispersants and leveling agents are commercially available products commonly used in the industry in appropriate amounts.

[0066] (2) Coat the UV-curable frosted coating described in (1) with a 200-300 mesh wire roller on a coating mac...

Abstract

The invention relates to a vacuum aluminum plating ground paperboard and a production method thereof, which belong to the technical field of package materials and printing materials. The vacuum aluminum plating ground paperboard comprises a paper base material, a ground coating layer and an aluminum plating layer. The production method comprises the following steps of: 1. making a ground coating mixing body; 2. coating a layer of ground coating mixing body on a paper substrate 4 for forming the ground coating layer; and 3. placing the paperboard comprising the ground coating layer with the grounding effect into a vacuum aluminum plating system, directly plating aluminum on the ground surface of the ground coating layer of the paperboard and forming the aluminum plating layer. The production method has the following advantages of simple process, no glue water layer, high production efficiency and no solvent volatilization, and belongs to the environmental-protection production process. The paperboard has exquisite and vivid ground effect and rich metal texture, and the produced ground paperboard can reach the screen painting effect through ordinary offset printing or gravure printing. A large amount of ink is saved, and the solvent volatilization and the solvent residue of printed products are greatly reduced.

Description

1. Technical field [0001] The invention relates to a vacuum aluminized frosted cardboard and a production method thereof, belonging to the technical field of packaging materials and printing materials. 2. Background technology [0002] At present, known aluminized cardboards for high-grade packaging materials include transfer aluminized cardboards, film-coated aluminized cardboards, and direct aluminized cardboards. It has been found from published patents and documents that the cardboard produced by the latter two processes is basically high-gloss cardboard, and the transfer method is also mainly used to produce high-gloss cardboard. If high-gloss cardboard is printed to obtain a rich texture and strong three-dimensional printing effect, screen printing is generally used, but the screen printing ink layer is thick, there are many solvent residues, and the printing speed is low, which is not suitable for high-end packaging materials. The low content control requirements of ...
