Specific implementation mode
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, rather than whole embodiments.Based on this
Embodiment in invention, those of ordinary skill in the art are obtained every other under the premise of not making performing creative labour
Embodiment shall fall within the protection scope of the present invention.
Refering to fig. 1, Fig. 1 is the flow diagram of one embodiment of production method of the imitative ceramic shell of the present invention.Wherein, should
Method includes：
Step S11：Housing base is provided；
Wherein, housing base has been molded but has not yet had the shell of the electronic equipment of ceramic appearance, including
The inner surface and the outer surface.Imitative ceramic shell in present embodiment can be the shell of electronic equipment, such as the battery of electronic equipment
Lid etc..
Specifically, referring to Fig. 2, in an application scenarios, step S11 includes：
Step S111：Shell base material is provided, and sawing sheet, polishing, forming processes are carried out successively to shell base material, to form shell
The shape of body；
In present embodiment, shell base material is glass, certainly in other embodiments, be can also be such as transparent plastic
Etc. other materials, it is not specifically limited herein.
Specifically, when carrying out sawing sheet to shell base material, glass sheet can be placed on to sawing sheet machine table top, coarse sand flywheel knife is opened
Shape outputs the camera shooting head bore etc. corresponding to electronic equipment, while unilateral staying 0.1mm surpluses.
After sawing sheet, grinding process is carried out to edge, and finish to shape and shooting head bore position etc., to be formed more
Fine shell shape.If in addition, needing 3D curved surface effects, 3D glass curve hot bending process can be used and realize 3D curved surface effects.
Step S112：Using ultrasonic cleaning shell base material, and further drying equipment is used to carry out drying and processing；
It is readily appreciated that ground, can have in the remained on surface of shell base material after carrying out sawing sheet, polishing, molding to shell base material useless
Slag in present embodiment, can be used ultrasonic wave and be cleaned to shell base material, clear water, deionized water or wine specifically may be used
Progress greatly row cleaning.
After cleaning, it can further be put into drying equipment such as baking oven and carry out drying and processing.
Step S113：Using cashmere wheel and assisted milling powder or foam solution, the shell base material after drying and processing is thrown
Light processing；
After cleaning up and drying, cashmere wheel can be used, finishing polish is carried out to the surface of glass shell, to form height
Bright fine and smooth surface.In polishing, it can be adjusted according to actual demand and polish wheel speed up and down, and control is to the pressure of shell
And polishing time, it is not specifically limited herein.
Step S114：After polishing treatment, intensive treatment is carried out to shell base material, is strengthened with being formed in shell substrate surface
Layer, and then obtain housing base.
In present embodiment, after polishing treatment, intensive treatment further is carried out to shell base material, it is hard to improve shell
Degree.
For example, the higher potassium nitrate solution of purity can be used with the mixed liquor of corresponding catalyst to glass shell
Learn cure process.
Specifically, referring to Fig. 3, in an application scenarios, step S114 further includes：
Step S1141：After polishing treatment, preset temperature is heated to default heating speed to shell base material；
Wherein, shell base material can be heated in closed environment using heat-treatment furnace, is needed in present embodiment
It is noted that the setting function of heat-treatment furnace can be utilized, heating rate, such as 3~8 DEG C/min are set, shell is delayed
Slow heat treatment.In present embodiment, shell base material can be heated 300 DEG C or so, or directly heat to 400~450 DEG C
Near temperature.
Step S1142：By the shell base material after heat treatment be immersed in temperature be 400~450 DEG C potassium nitrate solution and
3~4h is reacted in the mixed solution of catalyst；
Wherein, can mixed solution be heated to 400~450 DEG C in advance, it can be straight after shell base material is heated to preset temperature
It picks up out, and is immersed in the mixed solution so that the potassium ion and sodium ion on glass structure surface carry out ion exchange and shape
At strengthening layer.
Step S1143：After reaction, it is cooled to room temperature with default cooling velocity, to form strengthening layer in substrate surface,
And then obtain housing base.
It it should be pointed out that when being cooled down to shell, can also be placed in heat-treatment furnace, cooling velocity is set, with
Slow cooling is carried out to shell, so that because of being quickly cooled down embrittlement will not occur for shell.
In present embodiment, can control the time of entire strengthening process is that 4~5h may make after intensive treatment
The pencil hardness of surface of shell hardness up to 7H or so can also obtain the case hardness of other hardness numbers according to demand certainly, this
Place does not limit.
Step S12：Ceramic coating is formed in the inner surface of housing base and/or outer surface；
Step S13：Housing base to forming ceramic coating is handled, and is formed with the inner surface side in housing base
Inner lining film, to be revealed ceramic coating in housing base outer surface by inner lining film.
It, can be in the inner surface either outer surface or simultaneously in inner surface and appearance of housing base in present embodiment
Face forms ceramic coating.
Specifically, the material of ceramic coating is, such as can be with the oxide of silicon, titanyl compound, or can also be titanium-
The film structure of silicon-titanium, in particular to the oxidation titanium film sequentially formed, silicon oxide film, oxidation titanium film trilamellar membrane structure；It can be used
Vacuum evaporation or magnetic control sputtering plating coating machine form ceramic coating.
In an application scenarios, pottery is formed in the outer surface of housing base using vacuum evaporation or magnetic control sputtering plating coating machine
Porcelain plated film.
At this point, in the inner surface ink for screen printing of housing base, to form inner lining film in the inner surface side of housing base.This
It, can be with the ink of silk-screen different colours, such as white, black, to meet the different demands of user in embodiment.
Ink for screen printing with formed inner lining film can anti-light transmission, and then can play and set off ceramic coating, it is trueer to be formed
Real ceramic appearance.
In addition, shell inner surface side formed inner lining film, can further protect can with inner surface, to reduce shell
With electronic equipment internal component frictionally damage occurs for body.
In addition, in this application scene, further referring to Fig. 4, the production method of imitative ceramic shell further comprises：
Step S14：Using vacuum evaporation or magnetic control sputtering plating coating machine sequentially formed on ceramic coating diamond-film-like and
