Description
Technical field
The present invention relates to the ceramic rear covers and its processing method of a kind of mobile phone, belong to cell phone rear cover technical field.
Background technique
As the function of smart phone is become stronger day by day, it has been increasingly becoming the life assistant of the mankind, with people's lives at
For partner on very close terms.With the increase of this frequency of usage, the battery power consumption in mobile phone increases, and the charging frequency is simultaneously
Also increase, while every money mobile phone is equipped with a charger and charging cable, and there are Android system mobile phones and apple system hand
Machine is incompatible, and mobile phone charging wire is present in the every nook and cranny in room just as cobweb, and the appearance of wireless charging technology can
With this problem of very good solution.
With the appearance of zirconia ceramics mobile phone backboard, ceramic high-temperature stability provides new solution for wireless charging
Scheme, i.e., by printing electrocondution slurry on ceramic matrix, then burning infiltration is allowed to well attached with ceramics and forms galvanic circle, from
And reach the purpose of charging.Ceramic mobile phone rear cover is due to gentle jade sense, having a good decorative effect, and wireless charging
Technology has the characteristics that simply and easily.But it is printed in due to electrocondution slurry on the ceramic matrix that sintering is completed, such as technique shakiness
Surely it is low and fall off to will cause adhesive force, conductive coil contact and can be oxidized for a long time with air, and charge efficiency decaying is rapidly repeatedly.
Summary of the invention
It is an object of the invention to: in view of the drawbacks of the prior art, proposes a kind of ceramic rear cover of mobile phone and its add
Work method.
The technical scheme adopted by the invention is that: a kind of ceramic rear cover of mobile phone, including zirconia ceramics backboard and lead

Rear cover, the electrocondution slurry is formed through sintering and the integrated Wireless charging coil of zirconia ceramics backboard, wherein described
Electrocondution slurry with a thickness of 10-15 μm.
In the present invention: the raw material of the electrocondution slurry includes 8-20 part nickel powder, 30-60 parts of bronzes, 20- by weight
30 parts of tungsten powders and 8-20 parts of borosilicate glass powders.
A kind of processing method of the ceramic rear cover of mobile phone, includes the following steps:
Step 1: preparing the electrocondution slurry and the zirconia ceramics backboard；
Step 2: the electrocondution slurry is coated on the zirconia ceramics backboard, to the institute for being coated with the electrocondution slurry
It states zirconia ceramics backboard to be sintered, sintering temperature is 1200~1300 DEG C, keeps the temperature 2-3h, is formed and the zirconia ceramics
The integrated Wireless charging coil of backboard.
In the present invention: it includes: with 10 parts of oxygen by weight that the zirconia ceramics backboard is prepared in the step 1
Changing zirconium powder and 2-3 parts of glass powder is raw material, after mixing and ball milling is uniform, appropriate PVA aqueous solution is added as binder, will mix
It is potsherd green body that it is dry-pressing formed, which to close material,.
After adopting the above technical scheme, the invention has the benefit that the present invention will containing bronze, nickel powder, tungsten powder and
The electrocondution slurry that the raw material of borosilicate glass powder is prepared according to setting proportion, altogether with zirconia ceramics backboard one by the electrocondution slurry
It burns, realizes that Wireless charging coil is integrated with zirconia ceramics backboard, compared to traditional scheme, the present invention only good conductivity,
And the electrocondution slurry of this formula is in consistent sintering range with zirconia ceramics used, mutually ties both after one sintering
Conjunction effect is good, and the coil and zirconia ceramics of formation have very strong adhesive force.
