Abstract
A casing of electronic devices comprises a plastic casing, a metal coating and an oxidized layer formed on the surface of the metal coating by anodizing. The method for manufacturing the casing of electronic devices, including the following steps: (1) ejecting and forming the above plastic casing; (2) forming in metal coating on the surface of the plastic casing; (3) anodizing the plastic casing with the metal coating. In such a way, the casing of electronic devices has a metal sense and a strong erosion resistance. The method can continue the tinctorial processing after the step (3) to acquire the required color or pattern.
Description
[technical field]
The present invention relates to a kind of electronic device housing, relate in particular to a kind of electronic device housing with preferable outward appearance and surface quality.
[background technology]
At present, the electronic installation plastic casing often passes through plastic electroplating technology at this plastic casing surface deposition layer of metal layer in order to obtain metal-like.Related content can be with reference to United States Patent (USP) the 6th, 045, No. 866.But,, as copper, nickel etc., and than the active metal,, then be difficult to plate as aluminium etc. because plastic electroplating only can plate more inactive metal.In addition, because the technology of plastic electroplating own is comparatively complicated, so production efficiency is low and cost is high.
For addressing the above problem, United States Patent (USP) the 5th, 660 has disclosed a kind of method that obtains metal level by thermal spraying (Thermal Spraying) technology on plastics part No. 934.But, because this layer metal level on the plastics part directly contact with external environment, so easy contact with dirt and corroded.Simultaneously, the metal level color that said method produces is single, and decorative effect is also not good enough.
[summary of the invention]
The object of the present invention is to provide a kind of electronic device housing that metal-like and strong corrosion resistance and surface have required color or pattern that has.
The object of the present invention is achieved like this: electronic device housing of the present invention comprises plastic casing, metal coating and the oxide layer that forms through anode treatment on described metal coating surface.The manufacture method of this shell may further comprise the steps: the above-mentioned plastic casing of (1) ejection formation; (2) form the layer of metal coating on described plastic casing surface; (3) the described surface of anode treatment (Anodizing) has the plastic casing of metal coating.Above-mentioned manufacture method also can further be carried out painted processing after (3) step.
Compared with prior art, the invention has the advantages that: by above-mentioned manufacture method (2), (3) step, can make described electronic device housing have metal-like and strong corrosion resistance.By the painted treatment step after (3) step, make described electronic device housing surface obtain required color or pattern again.
[embodiment]
A kind of electronic device housing of the present invention comprises plastic casing, metal coating and the oxide layer that forms through anode treatment on described metal coating surface.In the present invention, this plastic casing is the synthetic of ABS (acrylonitrile-butadiene-styrene (ABS)) material or ABS material and other plastics.
The manufacture method of above-mentioned electronic device housing comprises the steps:
(1) the above-mentioned plastic casing of ejection formation;
(2) form the layer of metal coating on described plastic casing surface;
(3) this surface of anode treatment (Anodizing) has the plastic casing of metal coating.
Wherein, the present invention's (2) step can adopt thermal spraying, vacuum evaporation, sputter coating or ion plating to form metal coating on above-mentioned plastic casing surface.Described metal coating layer material can be the alloy of metals such as aluminium, titanium, magnesium or these metals.
The present invention is an example with aluminum or aluminum alloy material hot-spraying technique only, and the process that forms metal coating on above-mentioned plastic casing surface is described.
At first, the plastic casing behind the ejection formation is cleaned, carry out blasting treatment then, so that it combines with follow-up aluminum or aluminum alloy coating better.The selected quartz sand size of above-mentioned blasting treatment process is 1～3mm, and the surface roughness of the plastic casing after the sandblast is 4～15 μ m.
Then, the shower nozzle that the spray gun of aluminum or aluminum alloy powder is housed is placed position from plastic casing 150～350mm, each metal thickness such as aluminum or aluminum alloy that spray on plastic casing are at 0.1～0.4mm, until the aluminum or aluminum alloy coating that forms the about 0.6～1.2mm of a bed thickness on this plastic casing.Then this aluminum or aluminum alloy coating is carried out mechanical grinding, polish at last.Wherein, above-mentioned hot-spraying technique can adopt methods such as bank (Wire Arc) spraying, powder plasma (Powder Plasma) spraying or high-velocity oxy-fuel (High Velocity Oxy-Fuel) spraying to carry out.
Other are known by industry in the technology that the plastic casing surface forms the aluminum or aluminum alloy coating, do not give unnecessary details at this.
Be example with the aluminum or aluminum alloy coating more below, (3) step of above-mentioned manufacture method be illustrated in conjunction with following embodiment:
First embodiment: the housing of above-mentioned polishing is carried out electrochemical deoiling, and water cleans then, carries out chemical treatment afterwards, washes once more, then will this pretreated housing puts into one and electrolyte is housed and passes to galvanic electrolysis tank and handle.In the present embodiment, above-mentioned electrolyte is the mixed solution of sulfuric acid and sulfosalicylic acid (Sulfosalicylic Acid), wherein the weight percent concentration of this sulfuric acid is 0.1～1%, and the weight percent concentration of this sulfosalicylic acid (Sulfosalicylic Acid) is 10～20%.Above-mentioned dc voltage is 40～80V, and current density is 1～4A/dm2, and the processing time is 15 minutes to 1 hour, up to form coloured oxide-film that a layer thickness is 3～30 μ m at this surface of shell.The housing that this surface is had an oxide-film seals processing (SealingTreatment) at last.
Second embodiment: the housing of above-mentioned polishing is carried out oil removing, water cleans then, carry out electrolysis or chemical polishing afterwards, wash once more, then will this pretreated housing put into one and electrolyte is housed and passes to galvanic electrolysis tank and carry out anode treatment.In the present embodiment, above-mentioned electrolyte is sulfuric acid, and its concentration is 150～20000g/L.Above-mentioned dc voltage is 12～20V, and current density is 1～2A/dm
2, the processing time is 15 minutes to 1 hour, reaches 3～30 μ m up to oxide thickness.The housing that this surface is had an oxide-film seals processing at last.
Wherein in a second embodiment, can carry out painted processing so that this surface of shell obtains required color or pattern before sealing is handled through the housing after the anode treatment, wherein said painted processing can adopt adsorption coloring method or electrocolor process to carry out painted.
Owing to form other metal coatings on plastic casing surface, as titanium or titanium alloy, and it is similar to carry out process and the said process of technologies such as anode treatment, in this description one by one.
By above-mentioned manufacture method, thereby a kind of tool metal-like and stronger corrosion proof electronic device housing be can obtain, and can required color or pattern be obtained on its surface.
