Problems solved by technology

The production requires complicated process, high loss and high cost, and materials that are difficult to degrade such as PET film or OPP film are used
[0003] The current vacuum evaporation equipment requires all the evaporation materials to be placed in the vacuum chamber. Evaporation can only be carried out after one roll of transfer film is evaporated, then another roll of film is taken out, and then vacuumized, and continuous evaporation without stopping the machine is not possible. Plating operation, high energy consumption and low efficiency

Abstract

The invention discloses a vacuum direct-plating laser medium coated paper, and a preparation method and a preparation system thereof. The preparation method comprises the following steps: coating a base material with buffing oil: taking ivory board as a paper base material, coating the ivory board with UV buffing oil, and then irradiating and drying by adopting a UV lamp; calendaring the base material: carrying out continuous high-pressure heating and high-speed calendaring on the buffing oil-coated paper through a calendaring steel roller; carrying out information layer mould pressing: continuously heating the paper subjected to base material calendaring treatment through an impression roller to carry out laser information mould pressing; carrying out dielectric layer vacuum evaporation treatment: carrying out continuous dielectric layer vacuum evaporation on the paper subjected to information layer mould pressing treatment through a vacuum evaporation chamber provided with a multistage vacuumizing device, wherein the dielectric layer is aluminum, zinc sulfide and / or silicon dioxide; and carrying out protective layer coating treatment: coating the evaporated paper with a water-based coating protective layer to obtain the final coated paper. The coated paper and the preparation method thereof have the characteristics of simple process, environmental protection and high production efficiency.

Description

technical field [0001] The invention relates to the technical field of packaging and printing paper, in particular to a vacuum direct plating process laser medium coated paper, a preparation method and a preparation system thereof. Background technique [0002] The production process of traditional laser medium paper is as follows: figure 1 Shown: PET film or OPP film is coated with a layer of transfer paint, and then molded with laser information, and then vacuum aluminum-plated after molding to make a laser medium transfer film. Apply glue on the surface of the transfer film and compound it with paper. After compounding, it needs to be cured and dried for a period of time, and then the PET film or OPP film is peeled off with a peeling machine. Production requires complex processes, large losses, and high costs, and materials that are difficult to degrade, such as PET films or OPP films, are used. [0003] The current vacuum evaporation equipment requires all the evaporat...
