Description
Technical field
The invention belongs to technical field of electronic products, and in particular to a kind of use for electronic products sheet metal.
Background technology
Metal material such as stainless steel material, aluminum alloy materials start in the electronic products industry such as mobile phone, computer, camera
To being widely applied.But its color is single, decorates poor performance；Surface does not bear dirty, and it is dirty to be stained with fingerprint trace, greasy dirt and cosmetics etc.
It is difficult to clean off after dye object；Surface scoring resistance is poor, easily generates cut；In addition, under the dauer effect of moisture, spot etc., also
It can be by oxidation and dimmed.In spite of the texture that metal material is kept by film coating techniques such as plating, vacuum coatings, enhance simultaneously
The performances such as its decorative, scoring resistance and inoxidizability, but still its surface cannot be efficiently solved easily by pollutions such as fingerprint traces
The problem of object pickup.
Prior art discloses a kind of stainless steel decorated sheets, it includes covering as the stainless steel plate of substrate and on substrate
One layer 8-10 microns of polyester clear coat.Also prior art discloses a kind of aluminium alloy decoration plate, it includes making
For substrate, by print ink logo protect, topochemistry etch to be formed have matt canescence background color, smooth surface floral designs
Aluminium alloy plate and coated in one layer 4-7 microns of acrylate varnish on aluminium alloy plate.
The prior art solves stainless steel plate to a certain extent and aluminium alloy plate does not bear dirty, asking of easily being aoxidized and scratched
Topic, but their hardness, wearability and the performances such as corrosion-resistant are poor.It is only used for requiring not appearance property and performance
High product, it is impossible to meet the productions more demanding to appearance property and performance such as mobile phone, camera, laptop
The needs of product.
The content of the invention
The object of the present invention is to provide a kind of use for electronic products sheet metals, can meet such as mobile phone, camera, notes
The needs of the product more demanding to appearance property and performance such as this computer.
The present invention provides following technical solutions：
A kind of use for electronic products sheet metal, including metal substrate and ceramic coating, wherein, ceramic coating is water white transparency
Coating.
The present invention is after the processing such as mechanical surface chemical etching are carried out to the surface of metal base, in metal base table
Face is coated with one layer of ceramic coating, wherein, the ceramic coating is clear coat.
The mechanical surface pretreatment chemical etching processing is all technology known in those skilled in the art.Mainly it is
The oxide layer of metallic substrate surface is removed, so that the metal surface is formed specific roughness, gloss, lines or decorative pattern.Change
It learns etching and etching metal material surface is selectively dissolved using chemical reagent, so as to form word or pattern.
The metal base is aluminium alloy.There is decorative coating between the metal base and ceramic coating.In gold
Belong to substrate surface one layer of decorative coating of plating.
Aluminium alloy extrusions, by weight percentage content, it includes following components：The Fe of 0.1~2wt%, 0.5~3wt%
Cu, the Ni of the Zn of the Si of the B of 0.01~0.1wt%, 0.1~1wt%, 0.5~3wt%, 0.1~2wt%, 0.1~
The rare earth element of 2wt%, the Mo of 0.1~2wt%, remaining is aluminium and inevitable impurity.
In the rare earth element include at least La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb,
One kind in Lu, Sc, Y.
Aluminium alloy extrusions preparation method, step are：
The first step at 730~800 DEG C, in proportion refines each raw material, after stirring evenly, refined, slagging-off, degasification,
After 740~770 DEG C stand heat preservation 30min, cast bar is carried out in casting machine, cast bar is imported into milling train, the temperature for importing milling train is 500
~550 DEG C, export temperature is 350~420 DEG C, is heated in course of hot rolling.
Second step will be cold rolled to different size of aluminum alloy strip on aluminum alloy bar milling train.
3rd step, by aluminium alloy at 500~550 DEG C, the solution heat treatment of 4~8h.
The decorative coating has metal-like, the coating layer of color and luster to be various.Such as can be the coat of metal such as Ni,
Cu, Cr, Co, Ag, Au, alloy layer such as Cu-Sn, Cu-Zn, Cu-Au, Ni-Cr, Sn-Co, metallic compound coating such as TiN,
TiCN, TiCN, CrN, ZrN, nonmetallic compound coating such as diamond or by two or more groups in these coating
Close the double-colored or multi-color cladding coat formed.
The ceramic constituents of the ceramic coating include the inorganic compound of Al2O3, SiO2, TiO2.
The thickness of the decorative coating is 0.1-50 microns, and the thickness of crystalline ceramics coating is 0.1-5 microns.
The beneficial effects of the invention are as follows：The present invention is the ceramic coating in metallic substrate surface plating layer of transparent, the pottery
Porcelain coating only needs relatively low coating layer thickness of constructing, it is possible to have high rigidity, high-wearing feature, high scratch resistance, high antioxidant
With the performances such as high corrosion resistance.The effect of metallic substrate surface is easy to clean can also be assigned simultaneously.Due to used ceramic coating
Film layer is thin, transparency is high, therefore the appearance properties such as color, gloss and metal-like for maintaining metal base well.
