Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment plastic casing.
Embodiment
The plastic casing that the utility model provides comprises base material and the transparent film layer that is positioned on the described housing substrate surface, and wherein, this housing also comprises metallic diaphragm, and this metallic diaphragm is between substrate surface and transparent film layer.
As shown in Figure 1, the plastic casing that provides according to present embodiment comprises housing base material 1, is positioned at the transparent film layer 6 on base material 1 surface, and the metallic diaphragm 4 between base material 1 surface and transparent film layer 6.
Between metallic diaphragm 4 and transparent film layer 6, ink lay 5 is set, in order to embody the pattern color of product.Protect metallic diaphragm 4 simultaneously for the adhesion that increases between metallic diaphragm 4 and the base material 1, between metallic diaphragm 4 and base material 1, be provided with adhesive layer.The present embodiment adhesive layer is preferably two-layer, comprises first adhesive layer 2 and second adhesive layer 3 that is positioned on first adhesive layer 2 on base material 1 surface, and described first adhesive layer is an adhesive phase, and second adhesive layer is the gloss oil layer.
Described housing base material can be various plastic rubber substrates, the for example common plastic material that electronic product adopted is as polyester, polycarbonate, acrylonitrile-butadiene-styrene (ABS) ABS, polymetylmethacrylate or at least two kinds composite material among them
Described transparent film layer 6 materials have many kinds, as polycarbonate, and polyethylene terephtalate, polymetylmethacrylate etc.This example is selected the sheet material of PC material for use, and the moulding of PC sheet material and processing are all better, and surface gloss, anti-wear performance are also better.The PC sheet material that this example is used is the DMX light facesheet of GE company.
Before transparent film layer 6 moulding, need earlier on the PC sheet material moulding printing ink layer 5, metallic diaphragm 4, second adhesive layer 3, first adhesive layer 2 successively.
Described printing ink layer 5 is selected printing ink high temperature resistant, that adhesive force good, flexibility good and softening point is high for use.What present embodiment used is the N2K series ink of company of German Baolong: printing ink is the semi-transparent yellow green printing ink of N2K series, and diluent is selected N2K097-003 for use, and addition is 15%; Curing agent is selected N2K005 for use, and addition is 3%; Used printing process is a screen painting: select 150～300 orders/cm coloured polyester silk screen for use, solvent-resisting light sensitive layer, printing machine are conventional presses, and printing process is known for those skilled in the art, no longer too much describe herein.The PC sheet material that has printed printing ink is put in the baking box with 80 ℃ of bakings 30 minutes, made the solvent evaporates in the printing ink complete, finish-drying.
Described metal level 4 can be the various metal levels that can be plated on the described housing base material, and for example nickel, chromium, tin, indium, indium stannum alloy, aluminium or stainless steel make housing of the present utility model have the texture of metal.The utility model embodiment states metal level 4 and is preferably tin, the formation method of this metal level can adopt the whole bag of tricks, the preferred method that adopts physical vapor deposition (PVD) in the utility model, the method of physical vapor deposition (PVD) comprises sputter coating, ion film plating, evaporation coating, preferably adopts the method for evaporation coating.The method of evaporation coating adopts conventional method to carry out, and for example uses to rise and wins stove formula evaporation equipment, and vacuum degree is 1-8 * 10-2Pa, and pre-thermal power is 10%-30% (accounting for the percentage of gross power), warm-up time 10-20s; Fritting power 25%-35% (accounting for the percentage of gross power), fritting time 15-25s; Plated film power 30%-60% (accounting for the percentage of gross power), the plated film time is 15-25s.Sputter coating also is a conventional method, for example makes the horizontal coating machine of UFSOFT's prestige, cleans vacuum degree 1-5 * 10
-2Pa cleans power 600W, scavenging period 20s, plated film vacuum degree 2-5 * 10
-3Pa, plated film power 3KW, plated film time 2S, coating times is once.The rete of sputter coating is than the densification of evaporation, and is also thinner, and adhesive force is better than evaporation
Described second adhesive layer 3 adopts the transparent gloss oil of N2K093 of company of German Baolong, can pass through the typography moulding, to be attached with the cleaning of the PC sheet material of metallic diaphragm 4 before the printing, otherwise the dirty meeting on metallic diaphragm 4 surfaces causes that the aberration of printing and bubble etc. are bad.Printing equipment is identical with above-mentioned printing ink layer 2 with printing process.
Described first adhesive layer 2 adopts aqueous binder, and printing equipment is identical with above-mentioned printing second adhesive 3 with printing process.When having bubble to produce when causing printing because of adhesive meter is glutinous, can add some defoamer head it offs, general additional proportion is no more than 0.5%, in order to cooperate whole technology, present embodiment has printed adhesive three times, carry out again after every printing all will be dried for one time next all over the printing, and each all over the printing all to ensure the quality of products, prevent bad appearance such as aberration, impurity, bubble.
The PC sheet material that will finish above-mentioned operation cuts into the size that needs, and then the PC material is carried out compression molding, is the shape that cooperates with base material 1 outer surface with smooth PC sheet forming.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 PC sheet material that 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 PC sheet material to cooperate with base material 1 cut, be fixed to transparent film layer 6.Before base material 1 injection moulding began, the transparent film layer 6 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 6, after transparent film layer 6 is put into die, the injection molding material of base material 1 is injected at the inner surface of transparent film layer 6, makes injection molding material and transparent film layer 6 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.
