The invention also provides a portable electronic device, and the outward components of the device are prepared by adopting the board with the composite plated film.
Description
Technical field
The present invention relates to a kind of sheet material, relate in particular to a kind of sheet material and a kind of portable electron device that adopts this sheet material with composite film coating.
Background technology
Social now, the use of mobile phone more and more widely makes that the pollution of electromagenetic wave radiation is increasing, and electromagnetic wave not only can influence the normal operation of product itself, also possibly cause the injury of human body.When unwanted voltage or electric current exist and have a strong impact on device merit (property) can the time claim to take place Electromagnetic Interference (Electromagnetic Interference is called for short EMI); Change or what overcome that the method for this kind interference claims is Electromagnetic Interference control (or counter) (EMIcontrol is called for short EMIC).
With present, the method for the most general strick precaution external electromagnetic wave interference is to increase the electronic product external packing to electromagnetic screening capacity.Metal pair electromagnetic wave with high conductive capability has splendid assimilation effect and reflecting effect.The cell phone appearance part adopts effectively electromagnetic wave shielding of metallization, overcomes electromagnetic interference.Yet when the several sections of cell phone appearance part adopts metal material, because of human body also is a conductor, so when handheld mobile phone carried out communication, palm probably got up this a few part metal material UNICOM, causes electromagnetic wave crested communication bad.
Summary of the invention
In view of this, provide a kind of being used for can electromagnetic wave shielding, can prevent again sheet material that reception is bad and a kind of with composite deposite adopt the portable electron device of this sheet material real belong to necessary.
A kind of sheet material with composite film coating comprises the transparent optical thin layer that a metal base, a metal film layer and insulate.Said metal film layer is formed at said metallic substrate surface, and said optical thin film layer is formed at said metallic film laminar surface.Said metal film layer is used to eliminate the thin layer look that said optical thin film layer produces because of film interference.
A kind of portable electron device comprises appearance component, and said appearance component adopts said sheet material with composite deposite to process.
In prior art, the base material of sheet material according to the invention is a metal material, so effective electromagnetic wave shielding; In addition, the optical thin film layer of said sheet material is an insulating materials, so can prevent that reception is bad; Simultaneously, said metal film layer can also be eliminated the thin layer look that said metal film layer and said optical thin film layer produce because of film interference, therefore, can also keep the metal appearance of sheet material.
Portable electron device of the present invention has adopted said sheet material with composite deposite, and therefore, effectively electromagnetic wave shielding prevents that reception is bad, and can also keep metal appearance.

Optical thin film layer 16
The specific embodiment
To combine sheet material that accompanying drawing provides the present technique scheme and the portable electron device that adopts this sheet material to do further to specify below with composite film coating.
See also Fig. 1, present technique scheme first embodiment provides a kind of sheet material 10 with composite film coating, comprises a metal base 12, a metal film layer 14 and an optical thin film layer 16.Said metal film layer 14 is formed at said metal base 12 surfaces, and said optical thin film layer 16 is formed at said metal film layer 14 surfaces.
Said metal base 12 can be a simple metal, like Ni, Cu, Cr, Co, Ag or Au etc., also can be alloy, and like stainless steel, aluminium alloy, magnesium alloy, kirsite etc., in the present embodiment, said metal base 12 is No. 304 stainless steels of SUB.
Said metal film layer 14 is a simple metal coating, like Al, Ni, Cu, Cr, Co, Ag or Au etc.The generation type of preferred said metal film layer 14 is the vacuum plating, like sputter, vapor deposition or ion plating, to form the coating of specific thicknesses.
Said optical thin film layer 16 is transparent insulating materials, is titanium dioxide, tantalum pentoxide, niobium pentaoxide, alundum (Al, silica or zirconium dioxide etc. for example, and in the present embodiment, said optical thin film layer 16 is a silica.The generation type of said optical thin film layer 16 can be plated for vacuum, like sputter, vapor deposition or ion plating.
Said metal film layer 14 is used to eliminate the thin layer look that said optical thin film layer 16 produces because of film interference.Also be; For keeping the metal true qualities of said metal base 12; Can use the film interference principle to calculate the thickness of said metal film layer 14 of adjustment and said optical thin film layer 16, obtain surface color and the identical or approaching said sheet material 10 of said metal base 12 colors.
The color of object is used L-brightness, and a-red green, b-champac look represent, in the present embodiment; Measurement obtains said metal base 12 (SUB304 stainless steel) color, and (b) value is for (85.75,2.67 for L, a; 6.5), be that the material of 2200nm is the optical thin film layer 16 of silica with the surface of said metal base 12 plating thickness, obtain (L, a of said sheet material 10 colors; B) value is (80.01,2.56,6.57); Can find out except the L value, a of said sheet material 10 colors, b value and said metal base 12 are basic identical.Plating 3nm thickness of material is the metal film layer 14 of aluminium earlier on said metal base 12 surfaces, is the optical thin film layer 16 of silica in the surface of metal film layer 14 plating 2200nm thickness of material then, obtains (L, a of said sheet material 10 colors; B) value is (85.37,2.65,6.57); Can find out the L of said sheet material 10 colors, a; The L of b value and said metal base 12, a, the b value is corresponding identical or close.
In the present embodiment, basic identical for the color of the color that makes said sheet material 10 and said metal base 12 (SUB304 stainless steel), preferred said metal film layer 14 is 2-7nm, and the thickness of said optical thin film layer 16 is 2100-2300nm.
Be appreciated that; When said metal base 12 is other metal or alloy; Can use the film interference principle to adjust the thickness of said metal film layer 14 and said optical thin film layer 16 equally, obtain surface color or identical said sheet material 10 approaching with said metal base 12 colors.
