Embodiment
A kind of decoration of the present invention, be provided with leather, dry goods decorative layer, as leather classes such as corium, PU or PVC, and various textiles such as cotton or terylene class, be pasted with layer of plastic film at this decorative layer back side by adhesive, plastic film is meant polycarbonate (calling PC in the following text) film, polycarbonate (calling PET in the following text) film or propylene is fine, butadiene, styrene polymer (calling ABS in the following text) film etc., and this decoration has and the consistent shape of decorated position outer surface.
The manufacture method of above-mentioned decoration, specific as follows:
The first step, utilize coating machine on the back side of this decorative layer of rolling and plastic film, applying the layer of even adhesive in rolling, wherein this adhesive is the essential condition that decorative layer and plastic film are fitted smoothly, the selection of adhesive herein needs to decide according to the material of concrete decorative layer and the material of plastic film, the adhesive material can be polyurethane glue or epoxide-resin glue, and its concrete composition fibrous root decides according to the Textileather material that is adopted, thin-film material and their thickness;
Second step, and then utilize coating machine, decorative layer and plastic film are fit together, form laminated film;
The 3rd step, above-mentioned laminated film is placed on the drying plant toasts, make adhesive solidification, so that continuation subsequent handling, wherein the length of the height of adhesive solidification temperature and time is by the concrete composition and the proportioning decision of adhesive, and general temperature range is between the 70-90 degree, and optimum temperature is 80 degree, time range is between 15-25 minute, and Best Times is 20 minutes;
The 4th goes on foot, and the laminated film of the web-like after the above-mentioned oven dry is cut becomes required sheet size, and this is cut and can adopt cutting die automatic cutting or stamping machine automatic cutting, can certainly cut by hand;
In the 5th step, the laminated film to above-mentioned slitting slabbing carries out high-pressure molding then, makes it to become the THIN COMPOSITE putamina that has consistent shape with decorated position outer surface;
The 6th step was placed on above-mentioned THIN COMPOSITE putamina and carries out die-cutly on the punch die, made it to become the decoration that matches with decorated position.
Phone housing of the present invention, on this phone housing, be fixed with above-mentioned decoration, the plastic film of this decoration and the material of phone housing are all PC material, PET material or ABS material, require the material of phone housing must be essential identical with the material of plastic film on the decoration, could guarantee that like this combination between the two is very tight after the injection moulding, and this decoration have with this phone housing on the consistent shape of decorated position outer surface.
The manufacture method of above-mentioned phone housing, specific as follows:
To make the phone housing die cavity that the decoration that obtains is put into injection mold by said method, carry out ejection formation, the injection molding material of surface, decorated position on plastic film layers on the decoration and the phone housing is integrated, is about to decoration by in the phone housing injection molding process and injection moulding is fixed on the appearance of the decorative position of this phone housing.In addition,,, make on the surface at the decorated position of phone housing and contain decorative table, the die-cut face portion at decoration edge can be closed by this decorative table generally by the design of mould structure in order to prevent to be stripped from or rolled-up.
Please together referring to figs. 1 to Fig. 3, Textileather decoration provided by the invention comprises leather layer 1, adhesive layer 2 and plastic film 3 three-deckers.And phone housing comprises leather layer 1, adhesive layer 2, plastic film 3 and phone housing 4 four-layer structures.Be example with concrete manufacturing process below, to further instruction of the present invention:
When making, at first described adhesive layer 2 is coated on the surface of the back side of leather layer 1 of rolling and plastic film 3 by coating machine, wherein leather is the accurately machined high-quality ox-hide of process, plastic film material is a polycarbonate material, plastic film thickness is 0.25MM, leather thickness is 0.30mm, and the bondline thickness on plastic film and the leather is 0.15mm.On the leather and plastic film on all coated with adhesive be in order to improve behind follow-up attaching process the adhesion between them.Because this mode can be than only the adhesion of gluing can be high a lot of on a kind of material, adhesive need be selected the polyurethane glue of heat curing-type for use herein.
Adopt the pressure of 20bar leather layer 1 to be fitted in the surface of described plastic film 3 by coating machine then, form laminated film, it is for making leather can satisfy follow-up high-pressure molding requirement that plastic film 3 herein adopts polycarbonate film, because of polycarbonate film has good mouldability, by compressing leather layer 1 and plastic film 3 bonding, form after the laminated film, just can with script can't moulding leatherwork become our required external form.The laminated film of rolling is divided afterwards again and be placed on the Drying tunnel, the Drying tunnel temperature is set at the 70-80 degree, toasts 10-15 minute, and polyurethane glue is with regard to full solidification.Stamping cutting die cuts into our required sheet size with the laminated film of rolling afterwards.Again above-mentioned laminated film of cutting is carried out high-pressure molding, make it to be shaped to the three-dimensional plastic film shell that has consistent shape with the outer surface at the decorated position of phone housing, wherein the parameter of high-pressure molding is: clamping pressure: 120bar, low pressure: 10-15bar, the low pressure time: 10-15s, high-pressure gas pressure: 80-100bar, mold temperature: 80-100 takes the photograph this degree, IR prebake conditions temperature is the 200-350 degree, dwell time is 10-20s, and this pressure, temperature, the polycarbonate membrane of time according to concrete model decide.
Again the composite stereo film after the above-mentioned moulding is placed on that to utilize stamping machine to carry out on the die cutting die die-cut, cuts clout, form final decoration 5.Wherein above-mentioned die cutting die is according to product figure design, and the composite stereo film after the moulding can accurately be positioned on the die cutting die by its three-dimensional shape.
The injection mold die cavity of the decorative leather spare 5 of above-mentioned acquisition being put into above-mentioned phone housing 4 carries out injection moulding at last, and the injection molding material on plastic film 3 and the surface, decorated position of phone housing 4 on the decoration 5 is combined as a whole.The injection molding material on surface, phone housing 4 decorated position also is polycarbonate plastic (PC) plastics, because having only the injection molding material on surface, decorated position of phone housing 4 and above-mentioned thin layer is commaterial or character when close, the adhesion between them just can meet the demands.In addition by the design of mould structure, make to contain the decorative table 6 that is useful on leather fabric edge on the sealing decoration on the surface, the decorated position of phone housing, decorative table can be closed the exposed part at the edge of Textileather.
