The utility model provides a kind of shell, and this shell comprises shell base material and the color shifting ink layer that is positioned on the described shell substrate surface, and described shell also comprises transparent film layer, and this transparent film layer is positioned on the color shifting ink layer.
The utility model also provides a kind of electronic product, and this electronic product casing comprises shell base material and the color shifting ink layer that is positioned on the described shell substrate surface, and described electronic product casing also comprises transparent film layer, and this transparent film layer is positioned on the color shifting ink layer.
Shell according to the utility model provides also is provided with transparent film layer outside the color shifting ink layer of substrate surface, make this shell when having color changeable effect, and more wear-resistant, quality is more firm.
Description of drawings
The example structure schematic diagram that Fig. 1 provides for the utility model
Embodiment
Embodiment of the present utility model provides a kind of high-quality variable color shell.This shell comprises shell base material 1, be positioned at the color shifting ink layer 4 on the shell base material 1 and be positioned at transparent film layer 5 on the color shifting ink layer 4.
Described shell base material can be various base materials, for example common plastic material that electronic product adopted such as polyester, polycarbonate, acrylonitrile-butadiene-styrene (ABS) ABS, polymethyl methacrylate PMMA or at least two kinds composite material among them.
Above-mentioned plastic rubber substrate can obtain by prepared in various methods, for example, can obtain by existing various plastic rubber substrates are cut, and also can obtain by direct injection mo(u)lding.The method of described injection mo(u)lding has been conventionally known to one of skill in the art, for example can carry out injection mo(u)lding by using Sumitomo SE180DU injection moulding machine, obtains plastic rubber substrate.
Described transparent film layer 5 is made by transparent polymer sheet, and transparent polymer sheet can be formed by transparent arbitrarily filmogen.Because this transparent film layer 5 is as the outermost layer of plastic shell of the present invention, therefore, in order to make plastic cement have good resistance to wear, the material of transparent polymer sheet is preferably one or more in Merlon, polymethyl methacrylate, polymethyl acrylate, the PETG.
The reversible color material that described color shifting ink layer 4 can be temperature sensing color changing, photosensitive colour-changing, optic metachromatic material etc. adds in the water white water white transparency humour and makes.The temperature sensing color changing coating can the variable color with the change of ambient temperature; The photosensitive colour-changing material mainly contains silver chlorate, silver bromide, hexichol alkene class, volution class, norbornadiene class, triphenylmenthane analog derivative, salicylidene amino benzenes compounds etc.The coating of optic metachromatic material can be with the different different colours that present of viewing angle.Present embodiment adopts 5 -The trade mark that 25% reversible color material adds company of Baolong to is , HTR-093 printing ink in ground and made required color shifting ink, adopt screen process press (excellent seal silk screen bat printing mechanical apparatus factory, model are UP-S5070M) and 50-400 purpose half tone that color shifting ink is printed on the transparent polymer sheet then.Being baked to surface drying then under temperature is 90 degrees centigrade condition gets final product.
Preferably, can republish one deck background ink lay 3 after printing color shifting ink layer 4, described background printing ink is preferably dark colors such as black, purple, blueness.Because dark-background can absorb irradiation light preferably, the reverberation that make to produce reduces, and can alleviate background surfaces reverberation and reverberation interference effect from the color shifting ink layer like this, and color changeable effect is more obvious.Present embodiment adopts company of the Baolong trade mark to be , the black ink of HTR-952 can adopt various printing processes to form.Being baked to surface drying then under temperature is 90 degrees centigrade condition gets final product.
According to shell provided by the invention, under the preferable case, can between color shifting ink layer 4 or background ink lay 3 and base material 1, print one deck bond layer 2, the adhesion before can protecting between the ink lay of printing and increase ink lay and substrate layer surface.This bond layer can adopt company of the Baolong trade mark , Aquaprees The aqueous binders of ME adopts common silk screen printing, the multi-sheet printed formation of gradation.
The transparent polymer sheet that to finish above-mentioned operation cuts into the size that needs, and then transparent polymer sheet is carried out compression molding, smooth transparent polymer sheet is shaped to the shape that cooperates with base material 1 outer surface.Compression molding has strict requirement to Mould design and manufacturing.The die cavity that must be noted that shaping mould and injection mould cooperatively interacts, and the shape of the two, scale error should have very high machining accuracy.Avoid occurring the turnover of acute angle, the arc transition mode all should be adopted in every corner.Present embodiment is a high-pressure molding, promptly with the temperature more than 150 ℃ to the transparent polymer sheet of having carried out preheating on metal die with the air pressurized moulding.Forming process should be noted that and mix up forming temperature, and configuration pressure size and dwell time, this routine use equipment is LFORM100-A type high-pressure forming machine, 380 ℃ of forming temperatures, stoving time 7s, high pressure pressurization 41Kg, pressurize 6s, low pressure pressurization 7Kg then, pressurize 5s.Last exhaust 12s.
After the part that does not need on the transparent polymer sheet to cooperate with base material 1 cut, be fixed to transparent film layer 5.Before base material 1 injection moulding began, the transparent film layer 5 of setting was bumped into the injection mold from the back in advance.This injection mold comprises die and shaping mould (punch), the degree of depth in recessed membranous type chamber should be than the height of shaping mould the thickness of a big transparent film layer 5, after transparent film layer 5 is put into die, the injection molding material of base material 1 is injected at the inner surface of transparent film layer 5, makes injection molding material and transparent film layer 5 be bonded into the one curing molding.Present embodiment uses injection molding material to be PC7300, injection temperature 260-275 ℃.The method of described injection mo(u)lding has been conventionally known to one of skill in the art, for example can carry out injection mo(u)lding by using sea day 100 tonnes of injection moulding machines.
According to the plastic casing that the utility model embodiment provides, the thickness of formed adhesive layer 2 is
The 10-100 micron, be preferably the 30-70 micron, the thickness of formed background ink lay is the 10-50 micron, be preferably the 20-40 micron, the thickness of formed color shifting ink layer is the 10-60 micron, be preferably the 25-50 micron, and the thickness of formed transparent film layer is the 0.05-3 millimeter, be preferably the 0.15-0.75 millimeter.
The utility model also provides a kind of electronic product, and this electronic product comprises main body and the electronic product casing that matches with this main body, and wherein, described electronic product casing is an electronic product casing provided by the invention.
Described main body comprises the various elements that can realize the electronic product function that hold in this electronic product casing, and the kind of described each element, combination and annexation thereof are conventionally known to one of skill in the art, here repeat no more.
