Abstract
The invention provides a composite film panel which is composited by adhering two or more layers of polymer films; and the total thickness is 0.05-3mm. The polymer films are transparent films made from TPU (Thermoplastic Polyurethane), PC (Polycarbonate), PET (Polyethylene Terephthalate), PP (Polypropylene), PVC (Polyvinyl Chloride), PMMA (Polymethyl Methacrylate) and the like; character patterns or image patterns or both the character patterns and the image patterns are printed on each layer of polymer film and the adhesive for the compositing includes epoxy glue, modified epoxy glue, polyurethane glue, modified polyurethane glue, acrylate glue and the like. The upper surface of the uppermost layer of polymer film can be free of the patterns and the lower surface of the lowermost layer of polymer film can be adhered with a light guide plate or a cold light plate. The composite film panel has good flexibility and high bonding strength; different patterns can be printed on different layers of films; the combination of the films and the patterns is convenient and diversified; and the patterns on the layers of films do not contact and do not cause abrasion. The composite film is small in thickness, good in light transmittance and easy for slitting and can be used for making the thin key panels of cell phones, computers and the like.
Description
Technical field
The present invention relates to the panel of button, refer in particular to a kind of key panel that is composited by plural layers and multiple pattern.
Background technology
Usually, the key panel of mobile phone, computer etc. by injection moulding, drip mould, technology such as mold pressing makes, and mostly is individual layer or single material, the literal or figure of surface printing thereon then.These product varietys are single, and change in pattern is few, and are not attractive in appearance, and button thickness is bigger, and application places is restricted.
The product that thin film switch is arranged on the market with the figuratum film of printing and electric switch combination together, has certain attractive in appearance and safe effect.But it only has thin film and switch combination, and change in pattern is few, lacks stereoeffect, and pattern weares and teares easily.
Number of patent application is that 200810301519.8 specification discloses a kind of key panel structure, and it is pushed top layer, a patterned layer and by one and pushes bottom and form, and this patterned layer comprises that a sheet material and is formed at the ink lay of this sheet material.This application patent patterned layer has only one deck, and pattern is simpler, does not have multiple combination situations, does not have third dimension.
Number of patent application is the manufacture method that the specification of CN200710090648.2 discloses a kind of key panel of thin typeization, adopt mould and colloidal materials to make the multilayer panel in two-layer carrier and background color layer, font color layer, reflector respectively, though have elasticity preferably, but complex manufacturing technology, production efficiency is low, quality stability is not good enough, thickness low LCL is thin, and transparency is not high enough.
Summary of the invention
Goal of the invention: overcome traditional few defective of key panel change in pattern, a kind of different convenient various composite membrane panel of pattern, combinations of patterns of film printing of different layers is provided.
Technical scheme: composite membrane panel of the present invention, by two-layer or the layer high molecule film is bonding is composited, gross thickness is 0.05mm-3mm.Macromolecule membrane is the transparent membrane of TPU, PC, PET, PP, PE, EVA, CPE, CPVC, PVC, PMMA, silicon rubber, polyurethane rubber, ethylene-propylene rubber or acrylate rubber material; Be printed with character pattern, pictorial pattern on all or part of macromolecule membrane respectively or both all have, at the one side or the two-face printing of macromolecule membrane, printing is to adopt a kind of or several technologies in silk screen seal, offset printing, transfer printing, gold stamping, vacuum plating, plating, IMD, mechanical engraving, the laser engraving to realize.The adhesive of compound usefulness is the transparent adhesive of epoxy glue, modified epoxy, polyurethane adhesive, modified polyurethane glue, acrylate adhesive or modified acroleic acid ester gum; The printing material of adhesive and character pattern or pictorial pattern is compatible.
Printing material is because of physical absorption or chemical reaction with adhesive are out of shape, variable color, and perhaps distortion, variable color are not too obvious, so that character pattern or pictorial pattern keep enough definition.
Among the present invention, before the described macromolecule membrane printing, through the cleaning and the dried of a kind of or several organic solvents in ethanol, acetone, cyclohexanone or the ethyl acetate.Before the described film printing, can adopt corona or plasma treatment again,, increase the adhesion between printing material and the film to increase the macromolecule membrane surface activity.
Before described macromolecule membrane is bonding, adopt a kind of or several process in corona treatment, plasma treatment, radiation treatment, chemical treatment, mechanical treatment, dust removal process, the dried, to increase the macromolecule membrane surface activity, increase the cohesive force between the macromolecule membrane.
The character pattern of described part printing or pictorial pattern can be stereosopic printings or have the stereo display effect; Part pictorial pattern or can also have shaded effect.
The thickness of described orlop macromolecule membrane is greater than the thickness of other layers, and is easier when picking and placeing and cutting.
The adhesive of described compound usefulness is preferably the adhesive of epoxy glue, modified epoxy, polyurethane adhesive, modified polyurethane glue, acrylate adhesive or the modified acroleic acid ester gum of heat cured or UV photocuring.
Can there be printed patterns above the described the superiors macromolecule membrane yet.The following of described orlop macromolecule membrane can bonding light guide plate or cold light film.
Beneficial effect: composite membrane panel pliability of the present invention is good, and the situation that film bulk destroys can appear in each layer adhesive strength height during each layer film of tearing; The pattern that the film printing of different layers is different, the combined and instant of film and pattern is various, and it is low to make cost, the production efficiency height; And the pattern of each layer does not contact mutually, can not wear and tear; The integral thickness of composite membrane is thin, and light transmission is good, cuts easily, can be used for making the faceplate of thin shaped push button key in multiple fields such as mobile phone, computer.
