Preparation process of sliver vacuum aluminum-plated paper and transfer paint for paper

Abstract

The invention discloses a preparation process of sliver vacuum aluminum-plated paper and transfer paint for the paper. The adopted paint is composed of solvent-type acrylic resin, matting paste and a solvent including acetic acid-n-propyl ester and ethyl ester, wherein the mass ratio of solvent-type acrylic resin emulsion to the matting paste is 100:(0.3-0.8), the mass ratio of the solvent-type acrylic resin emulsion to the solvent is 100:(25-30), the mass ratio of the acetic acid-n-propyl ester to the ethyl ester in the solvent is (1.5-2.5):1, and the solid content of the solvent-type acrylic resin emulsion is 21%+ / -3% in terms of mass. The preparation process comprises the following steps that: the transfer paint is uniformly coated on a base film to form a uniform and dense transfer coating; a continuous and bright metal aluminum layer is further plated on the transfer coating to form a transfer film, and the transfer film and backing paper are bonded together by transfer glue; the base film is separated from the backing paper, so that the transfer glue, the aluminum layer and the coating are only left on the surface of the backing paper; and the stripped base film can be recoated for reutilization. The sliver vacuum aluminum-plated paper disclosed by the invention is good in leveling property and high in fastness. The preparation process has the advantages of effectively reducing process costs and the emission of VOC (Volatile Organic Compounds).

Description

technical field [0001] The invention relates to a preparation process of silver 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 composite glue; because 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 the composite paper (vacuum aluminized paper ) can be used for transfer coating on PET transparent transfer film, and it is not necessary to keep the film on the transfer paper, but the process of coating on the transfer film often requires secondary coating, and the cost of secondary coating is high , low production capacity; secondary coating VOC emissions are large; if the single coating process can be used to effectively solve the above problems, but the inventors found that the single coating process makes the vacuum me...

[0002] The composite paper process is a composite paper formed by bonding the film and paper together through composite glue; because 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 the composite paper (vacuum aluminized paper ) can be used for transfer coating on PET transparent transfer film, and it is not necessary to keep the film on the transfer paper, but the process of coating on the transfer film often requires secondary coating, and the cost of secondary coating is high , low production capacity; secondary coating VOC emissions are large; if the single coating process can be used to effectively solve the above problems, but the inventors found that the single coating process makes the vacuum metallized paper more prone to quality problems than the double coating process: Coarse lines, flooding, water ripples, longitudinal lines, black spots, poor peelability, poor fastness, high viscosity, etc.
