Description
Technical field
The present invention relates to a kind of electronic product casing and its process of surface treatment, especially a kind of (single in same housing
Part) surface present two kinds of gloss electronic product casing and its process of surface treatment.
Background technique
With making rapid progress for consumer electronics product, the product competition of various brands is fierce, and consumer is for consumer electricity
The requirement of sub- product is also higher and higher, in addition to hardware specification (such as processor, screen size and the pixel, network of electronic product
Standard, camera pixel etc.) outside, consumer also values the design of electronic product very much.
By taking current color vacuum coating technology treatment process as an example, a shell (plastic cement or hardware) can only accomplish a kind of table
Face sense of touch (full smooth surface, matte surface), while shell can only have single appearance color performance, can not same housing (plastic cement or
Hardware) on realize the metal-like effect of full smooth surface and matte surface simultaneously.Usually to meet this design requirement, it can only be by one
Shell (part) is split into two or more shells (part), then the shell (part) after partition is individually surface-treated,
It finally assembles integral.
Therefore, existing production method or single effect, can not meet the market demand or cause product shell it is complicated,
Increase manufacture difficulty, increase mold and Material Cost.
Summary of the invention
For overcome the deficiencies in the prior art, the purpose of the present invention is to provide a kind of electronic product casings of low cost
Process of surface treatment, the technique can realize a shell while have light region and dumb light region, so that there are two types of gloss for tool.
To achieve the above object, the embodiment of the invention provides a kind of process of surface treatment of electronic product casing, the works
Skill includes:
Spray-applied primer on the shell；
By vacuum coating, film plating layer is plated out on the priming paint；
It is painted in spraying on the film plating layer；
Coated matte finishing coat is painted in described；
Masking processing is carried out in the regional area of the dull finishing coat, sprays light on the dull finishing coat of masked processing
Finishing coat.
The embodiment of the present invention also provides a kind of electronic product casing, and surface is equipped with spray coating, which includes spraying
Priming paint on the shell, the middle paint for overlaying on the film plating layer on priming paint by Vacuum Deposition membrane cover, being sprayed on film plating layer are sprayed on
The light top coat top coat of the dull finishing coat painted and the regional area for being sprayed on dull finishing coat and covering dull finishing coat.
The invention has the following advantages: this technique is able to achieve specific ID effect demand, it is same on a housing parts
Shi Shixian smooth surface and mute face metal-like appearance, with the line of demarcation clear and definite that the time is mute, smooth surface and mute face are held in the mouth without offset
It connects, cooperation shape-designing makes product crest line clearly more demarcated.While realizing effect as above, this Vacuum Deposition process colour not by
Limitation, and industry reliability demonstration standard can be reached.
Detailed description of the invention
The present invention is described in detail with reference to the accompanying drawing:

4 are painted in spraying on the film plating layer 3；
The coated matte finishing coat 5 on the middle paint 4；
Masking processing is carried out in the regional area of the dull finishing coat 5, is sprayed on the dull finishing coat 5 of masked processing bright
Finish coat varnish 6, the region coated with light top coat top coat 6 are light region 61, and shielded region is dumb light region 51.
The priming paint 2 be ultraviolet light solidify (Ultraviolet Curing, UV) paint or polyurethane (Polyurethane,
PU it) paints, the middle paint 4 is ultraviolet-cured paint, and the dull finishing coat 5 is UV paint, and the light top coat top coat 6 is ultraviolet light solidification
Paint.
The vacuum coating using discontinuous coating technique (Non Conductive Vacuum Metalization,
NCVM) technique.
The priming paint 2 be it is transparent, the middle paint 4 is colored.
For the priming paint 2 with a thickness of 25-30um, baking temperature is 50 ± 5 °, and ultraviolet light solidification energy is 600-800mj/
cm2。
Vacuum coating is under vacuum conditions, to be intended to plating target by directly heating or indirect heating, be allowed to dissolve, then
Evaporation, or by solid sublimation be directly gas, the atom or molecule for obtaining enough energy fly to and be deposited on primed surface, sinks
The certain thickness film plating layer 3 of product.
For the middle paint 4 with a thickness of 8-10um, baking temperature is 55 ± 5 °, and ultraviolet light solidification energy is 500-700mj/cm2。
