It is arranged with the direction of center 12.The first surface 1341 can be the inner surface 131 of rear cover 13.The first surface 1341 is
The inner surface of the shell 11.The second surface 1342 faces away from the direction setting of cover board 11 and center 12.Described second
Surface 1342 is the outer surface of the shell 11.
The coloring layer 136 is set to the second surface 1342 of the substrate 134.
The coloring layer 136 can form layer of oxide layer by once oxidation.Such as: monochrome oxidation forms the oxidation
Layer, can specifically be formed by being coloured after oxidation technology.
It should be noted that in some embodiments, it is also possible to being formed using oxidation twice or oxidation more than twice more
Layer oxide layer.
In one embodiment, in order to enable the coloring layer 136 to be attached to the of the substrate 134 strongerly
Two surfaces 1342 can be processed by shot blasting the second surface 1342 of the substrate 134, to increase the of the substrate 134
The flatness on the surface on two surfaces 1342, to increase the coloring layer 136 in the second surface 1342 of the substrate 134
Adhesive force, and then the coloring layer 136 is enable to be firmly adhered to the second surface 1342 of the substrate 134.
In one embodiment, the coloring layer 136 can have multiple painted areas, and different painted areas settings are different
Color, to form pattern.
The coloring layer 136 may include a color layers 1361 and a hyaline layer 1362.Color layers 1361 and described
Hyaline layer 1362 is set in turn in the second surface 1342 of the substrate 134.The color layers 1361 can be above-described
Oxide layer.The hyaline layer 1362 can be celluloid paint layer.
It should be noted that the coloring layer 136 can not also include the hyaline layer 1362.
The protective layer 135 is set to the coloring layer 136.The color of the coloring layer 136 penetrates the protective layer
135, so that the protective layer 135 does not block the color of the coloring layer 136.The protective layer 135 is a graphene layer
In one embodiment, graphene oxide can be first prepared, Nano sol is then prepared, then by hydrophilic polymeric
The agent of object water-sensitive and crosslinking first solution of film forming agent formation soluble in water, then that Nano sol and the first solution be mixed to form second is molten
Then graphene oxide is added in the second solution by liquid, form graphene presoma.
The graphene presoma is coated on the coloring layer 136, then pass through drying and toasts the coloring layer 136
On graphene presoma obtain graphene layer.
In one embodiment, the graphene presoma can be coated by the way of spin coating, spraying or immersion
In on the coloring layer 136.
In one embodiment, the graphene presoma on the coloring layer 136 can be carried out using vacuum oven
Baking is to obtain graphene layer.
In one embodiment, the time of baking can be with 1 hour.In one embodiment, the time of baking can be 20
Minute was to 40 minutes.In one embodiment, the temperature of baking can be lower than 300 degrees Celsius.In one embodiment, baking
Temperature can be 100 degrees Celsius to 200 degrees Celsius.
In one embodiment, first layer graphene presoma can be first coated on the coloring layer 136, then passed through
Graphene presoma that is dry and toasting on the coloring layer 136 obtains first layer graphene layer, then again in the first layer
Second layer graphene presoma is coated on graphene layer, before then passing through drying and toasting the graphene on the coloring layer 136
It drives body and obtains second layer graphene layer, and so on, can be by repeatedly coating and toasting the step of, adjusts graphene layer
The number of plies, to control the thickness of the protective layer 135.
In one embodiment, the thickness of the protective layer 135 is less than 500 microns.When the thickness of protective layer 135 is greater than
At 500 microns, since the thickness of the protective layer 135 is larger, causes the photopermeability of the protective layer 135 poor, be easy to block
The color of the coloring layer 136.
In one embodiment, in order to enable the protective layer 135 to be attached to the coloring layer 136 strongerly,
The coloring layer 136 can be processed by shot blasting, to increase the flatness on the surface of the coloring layer 136, to increase
The protective layer 135 is in the adhesive force of the coloring layer 136, and then it is described so that the protective layer 135 is firmly adhered to
Coloring layer 136.
It should be noted that the structure of the embodiment of the present application shell is not limited to this, for example, referring to Fig. 5, Fig. 5 is this
Apply for another structural schematic diagram for the shell that embodiment provides.
