An important factor for.Therefore, the material requirements for making electronic product cover board has intensity high, heat-resistant antifriction is good, dimensionally stable,
The features such as appearance is good.The cover board of electronic product mostly uses greatly the materials such as engineering plastics, metal, glass to be made at this stage, these materials
That there are still hardness is low for material, it is easy scratch, deformation, fade, not environmentally, it is thermo-labile the disadvantages of.In recent years, beautiful, the beautiful matter with appearance
The ceramic cover plate for the features such as feeling, is wear-resistant, non-discolouring gradually obtains the favor of consumer.
CN201621186500.X discloses a kind of silver gray potsherd, the ceramic substrate including black or white, and
The transition zone set, first medium material layer, second medium material layer and third layer of dielectric material are successively plated positioned at substrate one side, and
Transition zone is silicon layer, and the Coating Materials of first medium material layer and third layer of dielectric material is selected from titanium pentoxide and five oxygen
Change one of two niobiums, the Coating Materials of second medium material layer is silica.Silver gray ceramics provided by the utility model
Piece is used in the front and back cover panels of the products such as electric appliances and instrument, toy such as mobile phone, remote controler, computer, has appearance pretty and dazzling brilliant,
Color durable and non-fading effect, and the silver gray potsherd does not influence the transmitting-receiving of electric signal, acid and alkali-resistance, bears dirty
Dirt, the corresponding technique of this patent and product are reliable and stable, the product completely can high-volume, large-scale production, filled up city
Field blank, meets the high demand of user.As it can be seen that being on a ceramic substrate which disclose a kind of silver gray potsherd
Plate optical thin film.But the optical thin film of the patent includes silicon, titanium pentoxide/niobium pentaoxide and silica, it is contained
Coating materials type is excessive, higher cost；And this specially uses a silicon as the transition zone between ceramic substrate and optical thin film, with pottery
The binding force of ceramic chip is not big enough, using the silver gray potsherd of the patent as mobile phone, the cover board of the electronic products such as computer, though
Right appearance is pretty and dazzling, but the time has grown optical thin film and has been easy to demoulding, and product is not durable.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of durable silver gray ceramic cover plate.
Technical problem to be solved in the utility model is achieved by the following technical programs:
A kind of durable silver gray ceramic cover plate, the color film being set to including ceramic substrate and plating on the ceramic substrate
