Abstract

The invention discloses a manufacturing method of a holographic anti-counterfeiting repeated transfer film. The method comprises the following steps that corona treatment is conducted on a PET base film; by the adoption of a 200-cable cable roller, the base film is coated with a first coating at set temperature through roll coating, wherein the first coating mainly comprises acrylic resin, cellulosic resin, auxiliaries, ethyl ester, butanone and a propyl methanoate solvent; the first coating is coated with a second coating, wherein coating materials of the second coating belong to double-component coating materials and the second coating mainly comprises melamine resin, curing agents, silicone oil, auxiliaries and a solvent; mould pressing is conducted, wherein a holographic template on mould pressing equipment is heated to set temperature, and pressing is conducted on the two coatings of the PET base film at set pressure to enable patterns on the holographic template to be transferred onto the two coatings. The transfer film manufactured by the adoption of the manufacturing method does not need the steps of coating and mould pressing any more, and holographic anti-counterfeiting aluminized transfer products can be produced directly.

Description

A kind of preparation method of holographic false proof repetitive displacement film

Technical field

The present invention relates to a kind of preparation method of holographic false proof repetitive displacement film.

Background technology

Along with the development of packaging industry, people are also more and more higher to the requirement of packaging base material, as the requirement of environmental protection, outward appearance, the aspect such as false proof, functional has all been improved relatively.The aluminium-plated packaging material of holographic false proof, due to its excellent apparent property, the degradability of finished product and antiforge function, substituted most of aluminum foil material, and application is more and more extensive.

At present the aluminium-plated transfer paper of holographic false proof or transfer paper sheet product processes successively flow process (see figure 1) be: coating, mold pressing, aluminize, compound, peel off, face is coated with, finished product, the PET film of peeling off can again utilize after product examine, and the part basement membrane that can reclaim must pass through coating and mold pressing and the new product of subsequent technique processing procedure again.

Summary of the invention

The preparation method who the object of the invention is to overcome the defect of prior art and provide a kind of holographic false proof repetitive displacement film, the transfer membrane that it prepares can no longer need, through coating and mold pressing, can directly again aluminize and subsequent technique is produced the aluminium-plated transfer product of holographic false proof.

Realizing a kind of technical scheme of object of the present invention is: a kind of preparation method of holographic false proof repetitive displacement film, comprises the following steps:

The step of corona, carries out sided corona treatment to PET basement membrane;

The once step of coating, the mode that adopts 200 line cable rolls and be coated with by roller, and on described PET basement membrane, be coated with the first coating with the temperature of setting, the material of this first coating is organic coating, belong to one-component tex, main component comprises acrylic resin 10%, celluosic resin 7%, auxiliary agent 1 ‰, ethyl ester 25%, butanone 25%, n-propyl solvent 10% and other solvents 23%, and wherein acrylic resin is main matter;

The step of secondary coating is coated with the second coating in the first coating, and the coating of this second coating belongs to dual-component coating, and main component comprises polyurethane resin 16%, curing agent 4%, auxiliary agent 1 ‰, silicone oil and solvent 80%;

The step of mold pressing, by molding apparatus mold pressing holographic false proof pattern on the PET basement membrane with the first coating and the second coating, holographic masterplate on molding apparatus is heated to the temperature of setting, and impress in the two layers of coatings of PET basement membrane with certain pressure, make design transfer on holographic masterplate on two layers of coatings.

The preparation method of above-mentioned holographic false proof repetitive displacement film, wherein, when the step that is once coated with, described coating temperature is 120~130 DEG C, and maximum temperature is lower than the softening point of the described acrylic resin in the first coating.

The preparation method of above-mentioned holographic false proof repetitive displacement film, wherein, while carrying out the step of mold pressing, the temperature of described holographic masterplate is 130~140 DEG C; Described pressure is 2.5~3.5kg.

The preparation method of holographic false proof repetitive displacement film of the present invention, the basement membrane that it prepares, can no longer need through coating and mold pressing, can be directly by aluminizing, compound, peel off, face is coated with and makes finished product, film after composite paper is peeled off, still there is false-proof hologram pattern, reusable, again aluminize.Adopt transfer membrane that method of the present invention prepares owing to having reduced the processing step of finished product production process, thereby greatly reduce whole production cost, reduced the environmental pollution that coating, mold pressing bring again, improved product competition strength simultaneously.
