Vacuum direct plating process laser medium coated paper and its preparation method and preparation system

Abstract

The invention discloses a laser medium coated paper with vacuum direct plating process and its preparation method and preparation system. Spread UV calendering oil, and then use UV light to irradiate and dry; substrate calendering treatment: pass the calendered paper through calender steel rollers for continuous high-pressure heating and high-speed calendering; information layer molding treatment: calender the substrate The processed paper is continuously heated by the embossing roller to emboss the laser information; vacuum evaporation treatment of the medium layer: the paper after the information layer is molded is subjected to continuous vacuum evaporation through a vacuum evaporation chamber equipped with a multi-stage vacuum device. Plating a medium layer, the medium layer is aluminum, zinc sulfide and / or silicon dioxide; protective layer coating treatment: coating the evaporated paper with a water-based paint protective layer to obtain the final coated paper. The coated paper and the preparation method of the invention 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...

AI Technical Summary

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
