Problems solved by technology

[0006] The aluminum-plated cardboard produced by the above three methods generally needs to use screen printing if you want to obtain printed products with rich texture, strong three-dimensional effect, bright lines and bright colors when printing graphic information, but due to the The ink layer of screen printing is thick, more than 30 microns, which is not suitable for printing patterns with fine lines. Compared with offset printing, its printing speed is low, and it is not suitable for printing large quantities of packaging materials.
Large amount of ink consumption, insufficient volatilization of ink solvents, printed products will continue to volatilize solvents for a long time, affecting the quality of packaging items

Abstract

The invention relates to electron beam-cured coating-containing vacuum aluminized sanding card paper which has a metal texture and a manufacturing method thereof. The electron beam-cured coating-containing vacuum aluminized sanding card paper is characterized in that an electron beam-cured sanding coating (3) and an aluminized layer (2) are sequentially covered on a paper substrate (4). The manufacturing method comprises the following steps of: preparing an electron beam-cured dope composition with a sanding effect; coating a layer of electron beam-cured dope composition-containing sanding coating on the paper substrate; and directly aluminizing in a vacuum aluminizing system to form the aluminized layer. The card paper can be reclaimed and degraded. In the subsequent process, the card paper can be printed and coated with colour; and then a screen printing effect can be achieved through offset printing or gravure printing. In a manufacturing process of the card paper, no solvent is volatilized; the efficiency is high; and the energy consumption is low. Therefore, the production process is an environmentally-friendly and high-efficient production process.

Description

1. Technical field [0001] The invention relates to a direct vacuum aluminized frosted cardboard containing an electron beam curing coating, which belongs to the technical field of packaging materials and decorative materials. 2. Background technology [0002] At present, the known aluminized cardboard used for packaging materials includes transfer aluminized cardboard, film-coated aluminized cardboard, and direct aluminized cardboard. [0003] The basic process of transferring aluminized cardboard: First, coat a layer of coating suitable for aluminizing on the PET film, heat and dry the coating, then aluminize the coating, and then use glue under pressure and heating conditions to make Aluminum layers are combined with cardboard. Then the PET film and the aluminum layer are peeled off by a peeling machine, and finally a layer of protective coating is coated on the peeled aluminum layer to form a transfer aluminized cardboard. The advantage of this process is that the consu...
