Abstract

The invention provides an in-die decorative ejection thin film structure and a manufacturing method thereof. The thin film structure takes a transparent substrate as a body, forms a decorative layer mainly provided with a photocuring adhesive layer on the top surface of the substrate, and enables the photocuring adhesive layer to present a refined stereo pattern preset on a female die in the mould pressing process by means of the characteristic that photocuring adhesive can be rapidly cured and moulded via UV-irradiation.Moreover, the photocuring adhesive layer is the outermost structure of the thin film structure, and an ink color layer is concealed between the substrate and the photocuring adhesive layer, thus greatly lowering the washout phenomena caused by displacement of the ink color layer due to high temperature deterioration and impact from ejected materials, improving yield of in-die decorative ejection processing, and being in no need of additional manhour and cost of reinforcing treatment by virtue of the high hardness, high chemical resistance and high abrasive resistance of the cured photocuring adhesive layer.

Description

Membrane structure and manufacture method thereof that in-mold decoration penetrates
Technical field
Membrane structure and manufacture method that the present invention penetrates about a kind of in-mold decoration, espespecially at the default photocuring glue-line of substrate, make it form required decorative pattern under mold pressing and illumination, to reach tool stereoscopic pattern effect and can improve membrane structure and the manufacture method thereof of decorative jetting process in mould yield.
Background technology
Mobile computer and mobile phone are quite universal high-tech electronic product, and in order to attract the consumer, not only usefulness is day by day gradually new, and the texture of shell and the fineness of layout also become one of main points of relevant manufacturer attention.Basically the shell manufacturing of mobile computer and mobile phone still be unable to do without the category of plastic processing, and three kinds of processing procedures that wherein often use are extrusion modling, ejection formation and hot-forming, wherein again with ejection formation for the most widely used technology at present.Ejection formation is mainly the die cavity of the plastics of melting being clamp-oned preset shape, after treating plastic cool, then opens mould finished product is taken out.Multinomial improvement has been passed through in the technical development of ejection formation, and develop the different technologies content that is fit to various product and processing procedure, the wherein manufacturing of high-tech electronic product casing is at present mainly penetrated (In-Mold Decoration, IMD) as mainstream technology take in-mold decoration.
See also Fig. 1, be usually used in the decorative jetting process in mould of high-tech electronic product casing, mainly comprise following steps (the following stated 1-5 steps flow chart corresponds respectively to Fig. 15 cross-sectional schematic from top to bottom):
1, thin film fabrication in response to the appearance design demand, comprises the following step:
(a) in transparency carrier 10 back sides formation one printing ink chromatographs 11, this printing ink chromatograph 11 presents unique design, to reach the demand of appearance design; And,
(b) again in bottom-surface coated one adhesion layer 12 of printing ink chromatograph 11, the just membrane structure 13 of complete formation one in order to penetrate in mould;
2, film forming, with mould 14 hot pressing, or the mode of high-pressure molding (High Pressure Forming), the configuration of soften film structure 13 is to fashion into required shape;
3, film slitting is cut or cross cutting is repaiied embrane method (Die Cut to Trim Film) and repaiied the external form of cutting out membrane structure 13 with cutter, to remove excess stock;
4, ejection formation is arranged at film the die cavity 15 of preset shape, and the injection material 16 of injection melting is waited for injection material 16 cooling formings to described die cavity 15, finished product can be taken out in die cavity 15; And,
5, intensive treatment is at finished product external appearance spray finishing polishes 17, to increase hardness, the wear-resisting and endurance of finished product outward appearance.
Comply with described typical thin films structure take a transparency carrier 10 as body, in described substrate 10 bottom-surface coated one printing ink chromatographs 11, this printing ink chromatograph 11 is provided with pattern to be presented, to reach the appearance design purpose, in described printing ink chromatograph 11 bottom coating one adhesion layers 12, this adhesion layer 12 supplies so that printing ink chromatograph 11 and injection material 16 stable bond again.
Substrate 10 materials of often selecting are selected from Merlon (PC) and any plastics of PETG (PET), wherein again take Merlon (PC) as good.
The injection material 16 of often selecting is selected from Merlon (PC), acrylonitrile-butadiene-styrene copolymer (ABS), polymethyl methacrylate (PMMA) and any plastics of Merlon mixing acrylonitrile-butadiene-styrene copolymer (PC/ABS) compound, the plastics that wherein more often use as industry take Merlon mixing acrylonitrile-butadiene-styrene copolymer (PC/ABS) compound again.
Yet, be subject to the typical thin films structure, described finished product appearance design is only plane pattern, can't produce the solid grain of tool sense of touch, and the mode with the printing ink drawing exists the technical limit, can't draw out the figure line of high-fineness, meet the requirements more and more higher aesthetic standard and design requirement, truly have weak point.
Simultaneously, except apparent deficiency, the structure setting of typical thin films, this printing ink chromatograph 11 only is separated by with injection material 16 with an adhesion layer 12, so printing ink chromatograph 11 is equivalent to directly be subject to the impact of injection material 16 in the step of ejection formation, be subjected to penetrate in processing procedure temperature, penetrate pressure and the parameter influence of ejaculation time, under certain Probability, the printing ink displacement that can be hit, and the red ink phenomenon occurs.In addition, because the common melting point of printing ink is 135 degree Celsius, and therefore the operating temperature of described injection material commonly used 16 usually makes printing ink be subjected to high temperature and go bad all more than 200 degree Celsius.Above situation all causes the production yield of decorative jetting process in mould too low.And be in response to described shortcoming, the coping style of existing employing is thickening printing ink chromatograph 11, or select the higher ink type of melting point, but these usual ways, not only increase production cost, also be subject to selectable ink type, and also can't solve the typical thin films structure fully and cause the too low shortcoming of decorative jetting process in mould yield.
More very it, coating adhesion layer 12 and coating polishes 17 are too time-consuming and increase extra production cost with two steps that strengthen product intensity, and do not meet cost consideration.
The decorative jetting process in mould technology of really attaching most importance in huge high-tech electronic industry, but the typical thin films structure in the finished product outward appearance, produce on yield and cost savings etc. consider, deficiency and disappearance part are all arranged, more perfect space is arranged in fact.
