The two plating of this vacuum transfer paper specifically realizes through following processing step:
1) on the PET basement membrane, be coated with release layer with multi-functional coating complex machine group (model is FTZ-1100B), release layer thickness is 1.6 microns-2.1 microns;
The PET basement membrane that 2) will be coated with release layer is dried, and bake out temperature is 60 ℃-120 ℃;
3) mold pressing of laser information is carried out in the oven dry rolling afterwards; It is the two ironed film moulding press of MYB-800 that molding apparatus adopts model, and the temperature of mold pressing for the first time is 120 ℃-145 ℃, and the temperature of mold pressing for the second time is 140 ℃-175 ℃; The purpose of secondary mould pressing is to guarantee that radium-shine PET basement membrane is seamless film; The material that causes because keeping away the version seam to avoid is scrapped, and mold pressing speed is 35-45m/min, and molding pressure is 3KG/CM
2
4) the radium-shine PET film after the mold pressing carries out vacuum aluminum-coatedly, and vacuum aluminum-coated machine is that model is the takeup type coating machine of ZZL-2000/0.8, and aluminum layer thickness is 0.038 micron-0.04 micron, and the purity of metal aluminum filament is 99.99%, and vacuum is 6 * 10
-2-9 * 10
-2Pa;
5) according to designing requirement and space of a whole page effect needs, needs are kept the part coating solvent type protective layer of metal laser effect, volatile dry, protective layer thickness are 1.2 microns-1.7 microns;
The radium-shine PET aluminizer that 6) will coat protective layer is immersed in the alkali lye pond location and washes aluminium, and speed is 35m/min-45m/min, and the pH value in alkali lye pond is 12-14, and its temperature is 50 ℃-65 ℃, rolling behind oven drying, and the bake out temperature of drying tunnel is 60 ℃-75 ℃;
Position when washing aluminium for the pattern of hachure or literal (about 0.08mm); Need when improving alkali lye pond temperature or concentration, suitably mention machine operating speed; To guarantee the definition and the integrity degree of lines, the pH value in alkali lye pond is about 13, and its temperature is 60 ℃-65 ℃; Machine speed is about 45m/min, and adopting model is the transparent aluminium washing machine of radium-shine film local laser of SX-1000B;
7) the radium-shine PET film washed behind the aluminium of location need pass through the corona PROCESS FOR TREATMENT, increases its surface tension, with improve dielectric layer and and protective layer and aluminium lamination between attachment fastness;
8) carry out a vacuum evaporation ZnS (medium) technology again after the corona, ZnS purity is 99.9%, and thickness of dielectric layers is 0.17 micron-0.2 micron, and vacuum is 6 * 10
-2-9 * 10
-2Pa, it is the vacuum coating equipment of ZZL-2000/1.1 that this vacuum evaporation process adopts model;
9) after vacuum evaporation ZnS technology, carry out washing process through the automatic rising machine group equipment and remove residual hydrogen sulfide odor, to guarantee the residual requirement that is up to state standards of VOCs smell of product, machine speed is 30-60m/min, baking temperature is 90 ℃-110 ℃;
10) radium-shine PET film coating transfer coatings and the paper after the washing carries out compound; Transfer coated thickness is 2.5 microns-3.0 microns; Carry out bake drying through drying tunnel then, drying tunnel temperature is 70 ℃-90 ℃, and dry film afterwards and paper are peeled off; Rolling respectively again, make paper, it is the fixed length stretching composite coating machine group of FTB1300M that equipment adopts model.
The utility model carries out vacuum aluminum-coated back with radium-shine basement membrane and washes aluminum technology through the location aluminium lamination is positioned processing; Make radium-shine film have transparent hollow out effect; Then radium-shine film is carried out a vacuum evaporation zinc sulphide (being commonly called as medium) technology again; Radium-shine like this membrane portions is because of keeping gloss and the brightness that aluminium lamination has metal, and part then has transparent laser effect.
From structure; The transfer membrane of this explained hereafter or paper are different with the existing transfer membrane or the paper number of plies; Have metal aluminium lamination and dielectric layer simultaneously; And the aluminum technology requirement is washed under situation about running up in the location, and the pH value of alkali lye and temperature have good matching, to guarantee integrity degree, the definition of fine pattern.
The utility model is mainly used in the printing in production cigarette-brand packages printing field with film or printing.
