preparation example Construction

[0041] The present invention also provides a method for preparing an impact-resistant shell material, which includes the following steps:

[0042] Provide surface materials and energy-absorbing materials, the surface materials are ceramics, glass-ceramics or ordinary glass, and the energy-absorbing materials are high-modulus materials;

[0043] Form the surface material into a surface layer and polish it;

[0044] forming the energy-absorbing material into an energy-absorbing layer;

[0045] The surface layer and the energy-absorbing layer are connected under preset temperature and pressure to obtain an impact-resistant shell material. The temperatures and pressures mentioned above are related to the materials being welded or bonded.

[0046] The above molding adopts tape casting or injection molding, and the appropriate molding method is selected according to the selected materials. For example, ceramic materials generally use tape casting, while glass, metal, fiber-reinfor...

Embodiment 1

[0055] Please refer to figure 1 , the impact-resistant housing material 100 described in the present embodiment comprises a surface layer 10, a connection layer 20 connecting the surface layer 10 and an energy-absorbing layer 30 connecting the connection layer 20, the surface layer 10 is a ceramic layer, and the energy-absorbing layer 30 is The ceramic layer and the adhesive layer adopt a glue layer or an adhesive film layer.

[0056] Correspondingly, the digital product casing made of the above-mentioned impact-resistant casing material 100 also includes the above-mentioned structure.

Embodiment 2

[0058] Please refer to figure 2 , the impact-resistant shell material 200 described in the present embodiment comprises a surface layer 10, a connection layer 20 connecting the surface layer 10 and an energy absorbing layer 30 connecting the connection layer 20, the surface layer 10 is a ceramic layer, and the energy absorbing layer 30 is The ceramic composite material layer, that is, the energy-absorbing layer 30 includes a first ceramic energy-absorbing layer 31 and a second ceramic energy-absorbing layer 32, and the first ceramic energy-absorbing layer 31 and the second ceramic energy-absorbing layer 32 are connected by glue or glue film , forming the middle adhesive layer 33 . The bonding layer adopts a glue layer or an adhesive film layer. Certainly, the composite material layer may also be a multi-layer composite, and is not limited to two layers.

Abstract

The invention discloses an anti-impact casing material, a production method thereof, a production method of a digital product casing and the digital product casing. The anti-impact casing material comprises a surface layer and an energy-absorbing layer connected to the surface layer; the surface layer is made with ceramic, glass ceramic or common glass; the energy-absorbing layer is made with a high-modulus material. The production method of the anti-impact casing material comprises: forming the surface layer with a surface material, polishing the surface layer, forming the energy-absorbing layer with an energy-absorbing material, connecting the surface layer and the energy-absorbing layer under a preset temperature and pressure so as to obtain the anti-impact casing material. The anti-impact casing material has the advantages that the surface layer can provide good surface effect and certain anti-impact capacity, the energy-absorbing layer made with the high-modulus high-toughness material can absorb impact energy and protect the surface layer, and the anti-impact capacity of the whole structure is improved.

Description

technical field [0001] The invention relates to the technical field of digital product casing preparation, in particular to an impact-resistant casing material, a preparation method thereof, a preparation method of a digital product casing and a digital product casing. Background technique [0002] With the approach of the 5G era, metal mobile phone back covers will gradually withdraw from the market due to their shielding effect on signals. The mobile phone back cover made of ceramic materials not only has no shielding effect on the signal, but also has the advantages of wear resistance, scratch resistance, high-end, skin-friendly, etc., and will become the darling of the mobile phone back cover market in the future. At present, the back cover of ceramic mobile phones has not been used on a large scale. An important reason is that the drop resistance is not enough. The poor drop resistance of ceramics is mainly caused by defects such as microscopic holes and cracks. These...
