Abstract

The invention relates to a process method for preparing laser aluminium-plated paper, comprising the steps as follows: OPP film or PET film is coated with a disjuncting layer which is coated with an imaging layer that is mould pressed with laser patterns; the mould pressing layer is coated with adhesive; the OPP film or the PET film is stripped and enwound by a stripping machine, thus obtaining a paper substrate containing the disjuncting layer, the imaging layer and the mould pressing layer; the paper substrate is directly plated with aluminium in vacuum and the aluminium is plated on the disjuncting coating layer; the aluminium-plated layer is coated with a waterborne environmental-protective profile coating protection layer; the laser aluminium-plated paper is obtained by moisture reobtaining and resolved shearing; the process of the invention reasonably chooses resin solvent and adhesive on the basis of a plurality of tests, simultaneously, the process of the invention utilizes suitable tenacity endowed by the molecular structure when the resin and the adhesive are in a coating state, and the performance of the adhesion to optimize the proportion according to the principle of combined surface tension gradient distribution between layers, thus forming the coating layer with high blare, good film-forming performance, environmental-protection and excellent printing performance and good alkali solution permeability simultaneously.

Description

technical field [0001] The invention relates to a composite material, in particular to a preparation method of laser aluminized paper. Background technique [0002] The method of vacuum aluminizing of laser aluminized paper generally adopts the transfer method. The transfer method of laser aluminized paper is to apply a release layer on the PET film, and then coat the bonding layer. Vacuum aluminizing is carried out on the bonding layer of the film. Apply adhesive on the layer, compound with paper, and then peel off the PET film with a peeling machine to obtain the product. [0003] The characteristics of the transfer method laser aluminized paper: (1) aluminum is plated on the bonding layer on the film substrate; (2) compounded after aluminizing, (3) the peeling layer adopts solvent-based coating. With the improvement of the grade of packaging and printing materials such as beer label paper, manufacturers and consumers have increasingly high-grade, beautiful, anti-counterf...
