Abstract
The utility model discloses a pre-coating film for improving the 3D (three dimensional) effect of digital printing. The pre-coating film sequentially comprises an organic silicon layer, a substrate film layer, a hot melt adhesive layer and an adhesive promoting layer from top to bottom, wherein the substrate film layer is a biaxially oriented polypropylene film (BOPP) or a biaxially oriented polyethylene terephthalate film (BOPET); the hot melt adhesive layer is ethylene-vinyl acetate or cycloaliphatic diene resin or a composite material of ethylene-vinyl acetate and cycloaliphatic diene resin; the adhesive promoting layer is di-aminosilane. The pre-coating film is high in compounding strength with digital printing paper; the adhesive promoting layer can be well adhered to a printed matter, and can infiltrate into the ink layer of the digital printed matter and spread to the paper substrate to form a net working structure with paper fibers, so that the pre-coating film has an ultrahigh adhesion on digital printing paper; the coated printed product is brighter and more beautiful in images and texts, and is richer in 3D sense, so that the 3D display effect of patterns can be improved.
Description
Technical field
The utility model relates to a kind of hot melt pre-coating film, more specifically relates to a kind of pre-coating film that improves 3D display effect for digital printing field.
Background technology
In digital printing field, the pattern of printing carries out overlay film conventionally, to improve the surface smoothing light of printed product, with glossiness and fastness, extend the work-ing life of product, has played the provide protection of waterproof, antifouling, wear-resisting, folding etc.But digital printing papery silicone oil and wax content are more, the compound good fastness of common overlay film is inadequate, and not good to the display effect of 3D pattern.
Summary of the invention
It is a kind of for improving the pre-coating film of digital printing 3D effect that the purpose of this utility model is to provide.
Of the present utility model for improving the pre-coating film of digital printing 3D effect, be made up of silicone layer, base material film layer, hot melt adhesive layer and adhesion promotion layer successively from top to bottom, described base material film layer is BiOriented Polypropylene Films (BOPP) or biaxially oriented polyester film (BOPET); Described hot melt adhesive layer is ethylene-vinyl acetate or ring grease dienes resin or is ethylene-vinyl acetate and the resinoid matrix material of ring grease diene; Described adhesion promotion layer is two aminosilanes.
Described ethylene-vinyl acetate and the resinoid matrix material of ring grease diene are made up of ethylene-vinyl acetate and the 10wt%-15wt% ring grease dienes resin of 85wt%-90wt%.
The thickness of described silicone layer is 0.01g/m
2.
Described hot melt adhesive layer thickness is 10-20 μ m.
Of the present utility model for improving the method for pre-coating film of digital printing 3D effect, it is base material film layer is unreeled and the upper surface of base material film layer is carried out to corona treatment, and then hot melt adhesive layer is melt extruded by casting method and is compound on the upper surface of base material film layer; The lower surface of base material film layer is carried out, after corona treatment, organic silicone oil being applied on the lower surface of base material film layer, dry; Meanwhile, be coated with the solution of two aminosilanes of 5wt%-10wt% on hot melt adhesive layer, and dry at 100 DEG C-110 DEG C, then carry out deburring, rolling, cuts.
Of the present utility model for improving the pre-coating film of digital printing 3D effect, high with digital printing paper combined strength bination, adhesion promotion layer can have good cohesive force with printed matter, permeable enter the ink layer of digital printing product, and then be diffused into paper substrate, form cross-linked network with paper fibre, logarithmic code printed sheet has superelevation cohesiveness; After overlay film, make print product picture and text color more bright-coloured attractive in appearance, be more rich in match volume, improved the 3D display effect of pattern.

Embodiment
As shown in Figure 1, of the present utility model for improving the pre-coating film of digital printing 3D effect, be made up of silicone layer 1, base material film layer 2, hot melt adhesive layer 3 and adhesion promotion layer 4 successively from top to bottom, described base material film layer is BiOriented Polypropylene Films (BOPP) or biaxially oriented polyester film (BOPET); Described hot melt adhesive layer is ethylene-vinyl acetate (EVA) or ring grease dienes (DCPD) resin or is ethylene-vinyl acetate and the resinoid matrix material of ring grease diene; Described adhesion promotion layer is two aminosilanes.The preparation of pre-coating film of the present utility model is to carry out corona treatment by base material BOPP thin-film unreeling and to its upper surface, and then be 20wt% by hot melt adhesive layer ethylene-vinyl acetate EVA(vinyl acetate content) melt extrude by casting method and be compound on the upper surface of BOPP thin film layer, again the lower surface of BOPP thin film layer is carried out to corona treatment, then be coated with organic silicone oil at the corona surface of BOPP film, simultaneously, be coated with the aqueous isopropanol of two aminosilanes of 5wt% at hot melt adhesive layer, and dry at 100 DEG C-110 DEG C, then carry out deburring, rolling, cut, obtain silicone layer, biaxially oriented laminated film, the pre-coating film of the four-layer structure that hot melt adhesive layer is connected successively with adhesion promotion layer.
