Embodiment 1

[0048] Step 1. Gravure printing on the inner layer of a polyester (PET) film with a width of 1250mm and a thickness of 30μm to produce a pattern layer with a predetermined effect after a polyurethane two-component ink and a transparent laser particle mixed resin. The average thickness of the ink layer is 1.6μm;

[0049] Step 2. Coating a polymethyl methacrylate (PMMA) weather-resistant resin layer with a width of 1240 mm and a thickness of 16 ± 1 μm on the outer surface of the polyester (PET) film;

[0050] Step 3. The pre-coated film is made by coating the water-based base coat by the extrusion laminating machine and extruding the composite hot melt adhesive resin. The primer layer is made of polyethyleneimine or ethylene-acrylic acid copolymer or polymer polyester aqueous solution, and the solid content is 0.7% to 5.5%; the dry weight of the primer layer is 0.07g / m 2 , The thickness is 0.04μm.

Embodiment 2

[0062] Step 1. On the inner layer of a polyester (PET) film with a width of 1250mm and a thickness of 30μm, gravure printed polyurethane two-component ink and transparent laser particles mixed with resin to produce a pattern layer with a predetermined effect;

[0063] Step 2. On the outer surface of the polyester (PET) film, coat a functional layer of a UV curable resin layer with a width of 1240mm and a thickness of 15±1μm, and then harden to form an anti-scratch layer after passing through a UV curing machine, and then rewind;

[0064] Step 3. On the solvent-free laminating machine, it is compounded with the 80μm thick PE heat-sealable film. The solvent-free two-component polyurethane adhesive resin is used. The cooling roller and the squeeze roller are used to combine with the PET film to form a glue. Floor. The aging period is 24h, and the peel force value is greater than 10N / 15mm. After slitting and trimming, a pre-coated film is made, and the total thickness of the pre-coate...

Embodiment 3

[0072] Using the coating machine dip coating process, the thickness of the single roll three dip coating is 12μm. The heat-sensitive adhesive is prepared from butanol-modified melamine resin, paraffin wax, rosin, 582 resin and solvent. The solvent is a mixture of methyl ethyl ketone and ethyl acetate.

[0073] Step 1. On the inner layer of a polyester (PET) film with a width of 1250mm and a thickness of 30μm, gravure printed polyurethane two-component ink and transparent laser particles mixed with resin to produce a pattern layer with a predetermined effect;

[0074] Step 2. On the outer surface of the polyester (PET) film, coat the brightening resin coating with a width of 1242mm and a thickness of 10±1μm, heat and dry it in the drying tunnel of the coating machine, and solidify to form a brightening functional layer, and then rewind;

[0075] Step 3. Dip-coating the heat-sensitive adhesive resin by a coater or dry laminating machine to form a pre-coated film. It is coated three ti...

Abstract

The invention provides a multicolor pre-coating film. The multicolor pre-coating film comprises a thin film layer, a colored layer, a laser layer, a hot melt adhesive layer and a protecting layer, wherein the thin film layer is taken as a carrier of each coating layer and is made of polyester materials; the inner surface of the thin film layer is coated with the colored layer which includes multiple colors printed simultaneously; the radium emanating layer is matched with the colored layer to form a predetermined pattern; the colored layer and the radium emanating layer are sealed in the inner surface of the thin film layer through the hot melt adhesive layer; the outer surface of the thin film layer is coated with the protecting layer which has the weather resistance and / or the scratch resistance. The pre-coating film can be directly stuck and connected to paper, furniture, a board, a plastic board, an aluminum-plastic panel, a steel plate and other materials through the hot melt adhesive layer under the condition of heating and pressurization and then can be covered. In the manufacturing and machining processes of the pre-coating film, benzene and ketones additives are not needed, and the total amount of residual solvents is less than or equal to 5.0 mg / m<2>, so that the national standard of GB / T10004-2008 is met. Pinholes of the pre-coating film are few, so that stainless steel plates or other metal plates are not needed to be used for conducting surface mechanical machining, and a great deal of cost can be reduced.

Description

Technical field [0001] The invention relates to the field of printing, in particular to a pre-coating film capable of simultaneously printing multiple colors on the surface of a metal plate and having an anti-counterfeiting function. Background technique [0002] The laminating printing in the prior art is generally monochrome printing. When multi-color printing is performed, it is necessary to print multiple times on a piece of printed matter according to the number of colors in order to perform chromatic printing, but this chromatic process needs to be very precise Control, the yield is not high. [0003] Under the limitations of the above-mentioned technology, there is no multi-color pre-coated film that can be used as an anti-counterfeiting mark on the metal sheet. Summary of the invention [0004] The purpose of the present invention is to provide a pre-coated film that can realize multi-color printing at one time and has a laser anti-counterfeiting function. [0005] In partic...
