preparation example Construction

[0028] The present invention also provides a method for preparing a mobile phone shell, said method comprising the following steps:

[0029] A, preparation sheet, it further comprises the steps:

[0030] After forming a metal layer on one surface of the base sheet 11, print the ink layer: the base sheet 11 can be a variety of plastic sheets, which require transparency or translucence, and have good stretch formability and temperature shock resistance , has a certain surface hardness, smooth or matte surface, brushed surface can be, for example, it can be one or more of transparent polycarbonate (PC), polyethylene terephthalate (PET) .

[0031] The metal layer is a layer of metal layer formed on the base sheet 11 through physical vapor deposition, electroplating, printing, spraying, etc. methods such as physical vapor deposition, electroplating, printing, spraying, etc. are known by those skilled in the art. It is well known and will not be repeated here. The metal layer is ...

Embodiment 1

[0041] The transparent base layer sheet 11 provided by Bayer is selected, the material is polycarbonate (PC), the model is DMX 1H00MY-112, both sides are glossy, the thickness is 0.175mm, and the specification is 230×200mm.

[0042] The operating surface of the base sheet 11 is coated with an indium-tin alloy by sputtering to obtain a metal layer with a light transmittance of 2%.

[0043] On the surface of the metal layer, an ink layer with a mesh pattern and positioning holes are printed. The ink used is XWR black ink provided by Powerlong, Germany. The screen used for printing is 300 mesh, and the printing thickness of the ink layer is 0.005mm. The circular holes in the mesh pattern are arranged regularly, the diameter of the circular holes is 0.3mm, and the hole spacing in the horizontal and vertical directions is both 0.6mm.

[0044] Put the above base sheet printed with metal layer and ink layer into the solution of model Rts-700 provided by Xinhongda Company for deplatin...

Embodiment 2

[0053] The transparent base layer sheet 11 provided by Bayer is selected, the material is polycarbonate (PC), the model is DMX 1H00MY-112, both sides are glossy, the thickness is 0.175mm, and the specification is 230×200mm.

[0054] The operating surface of the base sheet 11 is coated with an indium-tin alloy by sputtering to obtain a metal layer with a light transmittance of 4%.

[0055] On the surface of the metal layer, an ink layer with a mesh pattern and positioning holes are printed. The ink used is XWR black ink provided by Powerlong, Germany. The screen used for printing is 300 mesh, and the printing thickness of the ink layer is 0.01mm. The circular holes in the mesh pattern are arranged regularly, the diameter of the circular holes is 0.5 mm, and the hole spacing in the horizontal and vertical directions is 1 mm.

[0056] Put the above base sheet printed with metal layer and ink layer into the solution of model Rts-700 provided by Xinhongda Company for deplating, and...

Abstract

The invention provides a mobile phone shell, which comprises base materials and sheet materials adhering onto the surfaces of the base materials. The sheet materials include a base sheet material, a meshed metal layer, a meshed printing ink layer, an anti-scour printing ink layer and a bonding layer which are all sequentially arranged. The sheet materials are bonded with the base materials through the bonding layer, cavities are formed on the base materials, through holes matched with the meshed metal layer are formed on parts of the sheet materials and correspond to the cavities on the base materials. The invention further provides a manufacturing method of the mobile phone shell. The meshed metal layer formed on the surface of the mobile phone shell is thinner than an existing meshed metal sheet, thereby being light and free of signal shielding. The metal layer achieves metallic effect on the appearance and is variable in color. The outer surface is the sheet materials and in an integral structure, thereby achieving the integration of the appearance and the function and ensuring the consistency of surface decoration of products without affecting functional parts including loudspeakers and the like.

Description

technical field [0001] The invention belongs to the field of mobile phones, and in particular relates to a mobile phone casing and a preparation method thereof. Background technique [0002] With the development of consumer electronic products such as mobile phones, there are more and more metallic elements in the appearance of the product, but excessive use of metal parts as decorative or functional parts on the surface of the product will not only increase the weight of the product, but also The structure is more complex. Generally speaking, the decoration of the speaker hole of the mobile phone is inconsistent with the decoration of other parts. Usually, a metal mesh is embedded outside the speaker for decoration, or it is a complete through hole with a dust-proof net inside. Therefore, the decorative part and the functional part are separated, and the integration of appearance and function cannot be realized. [0003] At present, most of the earpieces, speaker holes an...
