preparation example Construction

[0027] At the same time, the present invention also provides a method for preparing the above shell, which is characterized in that it includes the following steps:

[0028] S1. Carry out perforation processing on the decorative layer, and form a through hole penetrating through the decorative layer on the decorative layer;

[0029] S2. Place the decorative layer on the surface of the fiber cloth pre-impregnated with pre-impregnated resin, and perform hot pressing, so that the pre-impregnated resin attached to the fiber cloth passes through the through hole, penetrates to the surface of the decorative layer and solidifies .

[0030] According to the present invention, first, a decorative layer having a desired decorative pattern is provided. As mentioned above, the decorative layer can specifically adopt an IMD (In-Mold Decoration Technology) decorative layer. In the present invention, there is no limitation on the pattern on the decorative layer. In order to facilitate the...

Embodiment 1

[0043] This embodiment is used to illustrate the casing disclosed in the present invention and its preparation method.

[0044] Take an IMD film with a thickness of 0.1 mm as the decorative layer. A plurality of evenly distributed through holes are formed on the decoration layer by using a mechanical drilling method, the diameter of the through holes is 0.2 mm, and the gap between the through holes is 0.4 mm.

[0045] Carry out sealing agent and release agent pretreatment on the mold.

[0046] After half an hour of pre-treatment, the carbon fiber cloth pre-impregnated with epoxy resin and the above-mentioned decorative layer that has been punched are laid out in sequence in the mold.

[0047] Close the mold and heat and press the mold, and heat and press the prepreg carbon fiber cloth and the decorative layer. The specific method of hot pressing treatment is: hot pressing at 200°C and 2MPa pressure for 10 minutes.

[0048] Open the mold and take out the product to obtain the ...

Embodiment 2

[0051] This embodiment is used to illustrate the casing disclosed in the present invention and its preparation method.

[0052] Take an IMD film with a thickness of 0.4mm as the decorative layer. A plurality of evenly distributed through holes are formed on the decoration layer by a mechanical drilling method, the diameter of the through holes is 1 mm, and the gap between the through holes is 0.3 mm.

[0053] Carry out sealing agent and release agent pretreatment on the mold.

[0054] After half an hour of pretreatment, the aramid fiber cloth pre-impregnated with polyimide and the above-mentioned perforated decorative layer are sequentially laid out in the mold.

[0055] Close the mold and heat and press the mold, and heat and press the pre-impregnated aramid fiber cloth and the decorative layer. The specific method of hot pressing treatment is: hot pressing at 300°C and 5 MPa pressure for 10 minutes.

[0056] Open the mold and take out the product to obtain the required sh...

Abstract

The invention provides a shell to overcome the problem that a decorative surface of the shell in the prior art is easy to wear. The shell sequentially comprises prepreg fiber cloth, a decorative layer and a resin protection layer, wherein the resin protection layer packages the decorative layer on the surface of the prepreg fiber cloth. Meanwhile, the invention further discloses a manufacturing method of the shell. The shell provided by the invention has high abrasive resistance and is not easy to wear; the surface layer is good in texture; and local decoration can be achieved according to the requirements.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a casing and a manufacturing method thereof. Background technique [0002] With the rapid development of science and technology, various electronic devices emerge in an endless stream and continue to develop towards high-end. For example, electronic devices such as mobile phones, tablet computers, notebook computers, and MP3 and MP4 players are increasingly developing in the direction of large screens, thinner and lighter, and rich appearance effects. At present, the materials used to make electronic equipment casings include plastics, stainless steel, aluminum alloys, and carbon fiber materials. Among them, carbon fiber materials are widely used in this field due to their high strength, light weight, high toughness and good heat dissipation effect. At present, the main production method of carbon fiber shell is: pre-impregnate carbon fiber with resin, heat and pressurize an...
