Preparation process of laser golden vacuum aluminized paper and transfer coating used for preparation process

Abstract

The invention discloses a preparation process of laser golden vacuum aluminized paper and a transfer coating used for the preparation process. The transfer coating consists of solvent type acrylic resin emulsion, paint type color paste and a solvent including n-propyl ester and butanone, wherein the color type color paste comprises color paste yellow and color paste red; the mass ratio of the solvent type acrylic resin emulsion to the color paste yellow to the color paste red is (9-11): (0.8-1.2): (0.08-1.2); the mass ratio of the solvent type acrylic resin emulsion to the solvents is 100: (1.5-2.5); the mass ratio of the n-propyl ester to the butanone in the solvent is (0.5-1.5): (0.5-1.5); the transfer coating is uniformly coated on a transfer transparent base film to form a uniform and compact transfer coating and then a continuous bright metal aluminum layer is plated to form a transfer film; the transfer film is adhered to bottom paper by using a transfer adhesive; the base film is separated from the paper sheet, so that only are the transfer adhesive, the aluminum layer and the coating remained on the surface of the paper sheet; and the stripped base film can be newly coated and reutilized. According to the preparation process, the process cost can be effectively reduced, and the displacement of VOC (Volatile Organic Compounds) is reduced.

Description

technical field [0001] The invention relates to the preparation process of laser gold vacuum aluminized paper and the transfer coating used therein. Background technique [0002] The composite paper process is a composite paper formed by bonding the film and paper together through a composite glue; since there is a layer of film on the composite paper, the composite paper is not easy to degrade, cannot be recycled, and is not environmentally friendly; although vacuum aluminum-coated paper can be used in PET Transfer coating on the transparent transfer film does not need to leave the film on the transfer paper, but it often requires secondary coating during the coating process on the transfer film. For the coloring of vacuum aluminized paper, some processes use a single-coating and post-coloring process, which is to coat a layer of varnish on the surface after the paper is compounded, which is to color on the paper; some use the pre-coloring process It is to add color paste ...

Problems solved by technology

[0003] The inventor considers that the coloring before single-coating can effectively solve the above problems through research; but it still needs to be solved that orange peel and rainbow lines are easy to appear in the coloring process before single-coating; Version, color overflow and other phenomena; and problems such as unstable hue
