Specific embodiment

Embodiment 1

A kind of decorating film（As shown in Figure 1）, it is bonding on steel plate, successively including decorative layer 3, following layer 2, PET base material layer 1, the coat of metal 4, adhesive phase 5, layer of PVC 6, hot melt adhesive layer 7, the decorative layer 3 is placed in steel plate outermost, on the decorative layer 3 It is carved with fine sense of touch decorative pattern 11,12 or 14（As shown in Figure 3）, word and logo etc. are without sense of touch picture and text（Such as laser graphic 13）. " sense of touch " is surface fine texture and concavo-convex tactile textures, and " without the sense of touch " is that surface is smooth.

The thickness 20um-200um of the PET base material layer 1, material two-side corona, its surface tension reaches more than 50 dynes（Bag Include this number）, the two-sided corona material of preferably 36 microns thickness；The main component of the following layer 2 is crylic acid resin, to improve The binding strength of PET base material layer and decorative layer.

The decorative layer 3 is ultraviolet-curing paint；The thickness of the decorative layer 3 is 12-20um, above the decorative layer 3 Fine sense of touch pattern depth is 15-18um.The sense of touch pattern depth is the cup depth less than decor surface.The bonding Oxidant layer includes the components such as fire retardant, paraffin, oleic acid, polyvinyl alcohol, ammoniacal liquor, water.The hot melt adhesive layer is EVA material, is easy to use Family direct combination is on metallic plate, home appliance panel, aluminium-plastic panel, furniture, electronic product casing.

A kind of manufacture craft of decorating film is：

First, the roller coating following layer 2 above PET base material layer 1.

Secondly, disposably pressed in the coating following layer 2 of PET base material layer 1 using drop coating or roller coating ultraviolet light polymerization molding apparatus Print decorative layer 3.

Molding apparatus manufacture craft is：The fine depth sense of touch of decorative layer 3 obtained on unit mother matrix by laser engraving Decorative pattern, word and logo etc. are obtained without sense of touch picture and text by radium-shine mask-making technology on unit mother matrix.Said units mother matrix is adopted With UV layouts fabrication techniques into molding mother matrix, by molding mastering into the nickel version of suitable molding apparatus, it is molded in molding apparatus Above-mentioned nickel version is coated in roller.

Due to being the various patterns of fusion and the molding mother matrix of fine textures effect and concavo-convex sense of touch in nickel version.And due to each list First mother matrix adopts UV layout technologies, electroforming to obtain being adapted to the molding mother matrix of molding apparatus model and product wide cut specification.Therefore the mother The product that version is made has merged the grain effects such as radium-shine, wire drawing, sense of touch decorative pattern, and class surcharge is high（As shown in Figure 3）.

Then, the mother matrix is coated on ultraviolet light polymerization molding apparatus on stencilling wheel, and bag version version seam ± 0.2mm is left for control It is right.Another corona surface of PET base material layer after molding decorative layer plates the coat of metal 4, and the thickness of the coat of metal 4 is 150 to 550.

Then, coating adhesive layer.

Finally, layer of PVC and hot melt adhesive layer are coated with over the binder layer.

The present embodiment makes holographic cell mother matrix, various band fine surface textures and concavo-convex tactile textures using photoetching technique The making of the unit mother matrix such as effect causes product to produce gorgeous rainbow laser effect.And personalized pattern, word, enterprise, product The mark action of product brand logo and one, and with physical and chemical performances such as good high temperature resistant, acid and alkali-resistance, scratch-resistants.

Embodiment 2

As shown in Fig. 2, a kind of decorating film（As shown in Figure 2）, successively including PET base material layer 1, following layer 2, decorative layer 3, The coat of metal 4, the decorating film 3 of the present embodiment is used for in-mold decoration, i.e. decorative layer 3 and is located at the inner side of PET base material layer 1.The coat of metal 4 Coat the side of decorative layer 3.The thickness of the PET base material layer 1 is 180um, and metal wire-drawing line 10 and radium-shine is arranged on the decorative layer 3 Picture and text 13.

As described in Example 1, difference is the manufacture craft of the present embodiment：

1. need to make metal wire-drawing line, laser graphic unit mother matrix.The fine of embodiment 1 is omitted i.e. on decorative layer 3 Depth sense of touch floral designs unit mastering process；

2. in-mould injection technique is adopted, to omit coating adhesive layer, layer of PVC and the hot melt adhesive layer of embodiment 1.

The present embodiment is due to using in-mould injection technique, it is no longer necessary to adhesive phase, layer of PVC, hot melt adhesive layer.It is decorated molded It is overall afterwards that metallic luster, drawing pattern, radium-shine rainbow variation effect is presented.The class and decorative visual of the effective improving product of the technique Effect.Can be used for using on the appliance shell of in-mold decoration processes, electronic product casing.

Above example only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple Other modifications or equivalent that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, all should cover in right of the present utility model.
