[0076] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0077] In the related technologies, in order to meet people's diversified needs and make electronic devices more competitive, electronic device manufacturers are committed to developing electronic device shells with various appearance effects. Among them, the light-matt same-body shell refers to the shell that presents both glossy and matte effects at the same time. For example, the identification area (such as the logo) of the shell is made into a glossy effect, and the other areas of the shell are made into a matte effect. In this way, the shell as a whole can have a high-end texture of frosting and anti-glare, and the logo area can be highlighted, thereby enhancing the visual impact and high-end texture of the product.

[0078] In the matte monolithic shell provided in the related art, the brightness and glossiness of the bright area are limited by the brightness and glossiness of the shell itself, and the visual effect of the matte monolithic shell is not good. Therefore, this also restricts the development of the matte monolithic shell.

[0079] Based on this, the present disclosure provides a shell, which includes a main body, a logo, a coating layer and an ink layer. By stacking the coating layer and the ink layer on the second surface of the main body, the brightness of the area of ​​the shell can be improved; and the setting of the coating layer and the ink layer can make the bright effect of the shell no longer limited by the influence of the appearance of the main body itself, thereby providing a richer appearance visual effect for improving the shell.

[0080] In an exemplary embodiment of the present disclosure, a housing is provided, such as Figure 1 As shown, the housing includes a body 1, a logo 2, a coating layer 3 and an ink layer 4, and wherein

[0081] The logo 2 is disposed on the first surface 11 of the body 1;

[0082] The coating layer 3 and the ink layer 4 are stacked on the second surface 12 of the body 1, wherein the second surface 12 is arranged opposite to the first surface 11;

[0083] Along the thickness direction of the body 1 , the projections of the coating layer 3 and the ink layer 4 cover the projection of the area where the logo 2 is located.

[0084] In this embodiment, by stacking the coating layer 3 and the ink layer 4 on the second surface 12 of the main body, the brightness of the shell in this area can be improved; and the setting of the coating layer 3 and the ink layer 4 can make the brightness of the shell no longer limited by the appearance of the main body 1 itself, thereby providing a richer visual effect for improving the appearance of the shell.

[0085] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the first surface 11 of the body 1 includes a matte area 11a and a first glossy area 11b;

[0086] The logo 2 is arranged in the first light surface area 11 b.

[0087] The logo 2 may be a pattern, design, number or trademark that needs to be highlighted on the shell. In this embodiment, the logo 2 is set on the first glossy area 11b of the first surface 11, and the other areas of the first surface 11 are matte areas 11a, so that the logo area on the shell presents a glossy effect, while the other areas present a matte effect, thereby forming a glossy and matte homogeneous effect.

[0088] The positions and areas of the first glossy area 11b and the matte area 11a on the first surface 11 can be set as needed and are not limited here. Figure 1 As shown, the first surface 11 includes a first glossy area 11b and two matte areas 11a respectively located on both sides of the first glossy area 11b, and the area of ​​the matte area 11a is larger than the area of ​​the first glossy area 11b. In this way, the shell can have a large area of ​​frosted and anti-glare effects, and can highlight the logo area, thereby enhancing the visual impact and high-end texture of the shell.

[0089] In an exemplary embodiment of the present disclosure, the second surface 12 of the body 1 includes a second glossy area, and the coating layer 3 is disposed on the second glossy area. In this embodiment, the coating layer 3 is disposed on the second glossy area, which is beneficial to improving the brightness of the area of ​​the housing. Figure 1As shown, the entire second surface 12 is the second polished surface area. The coating layer 3 can be directly disposed on the second polished surface area, so that the second polished surface area is completely covered by the coating layer 3.

[0090] Among them, Figure 1 As shown, when the second glossy area is completely covered by the coating layer 3, the ink layer 4 can be directly arranged on the coating layer 3, so that the coating layer 3 is completely covered by the ink layer 4. It can be understood that when the housing needs to display a bright effect in the area where the logo 2 is located, other effects need to be displayed in other areas, such as Figure 2 As shown, the ink layer 4 is only provided on the coating layer 3 at the projection position of the logo 2. For example, in order to enrich the appearance of the housing, it is necessary to attach a decorative film to the surface of the matte housing. In this case, the ink layer 4 is only provided on the coating layer 3 at the projection position of the logo 2, which can make the logo area present a bright effect and avoid the ink layer 4 from blocking the decorative film.

[0091] It is understandable that in order to reduce the loss of the target material and reduce the coating area, the coating layer 3 may also be disposed on a portion of the second light surface area. Figure 3 As shown, in an exemplary embodiment, along the thickness direction of the body 1 , the coating layer 3 is disposed on the second polished area at the projection position of the logo 2 .

[0092] In an exemplary embodiment of the present disclosure, the coating layer 3 is a silicon oxide layer and / or a titanium oxide layer. In this embodiment, the coating layer 3 is a silicon oxide layer and / or a titanium oxide layer, thereby obtaining a colorless brightening coating layer to improve the brightness of the housing. The silicon oxide layer may be a silicon dioxide layer, and the titanium oxide layer may be a titanium dioxide layer.

[0093] Exemplarily, the coating layer 3 may be a silicon oxide layer alone, a titanium oxide layer alone, or a silicon oxide layer and a titanium oxide layer.

[0094] In an exemplary embodiment, when the coating layer 3 is a silicon oxide layer and a titanium oxide layer, the silicon oxide layer and the titanium oxide layer are sequentially arranged. In this embodiment, when the coating layer 3 is a silicon oxide layer and a titanium oxide layer sequentially arranged, the obtained coating layer 3 not only has good chemical stability, but also has good brightening transparency, which can play a role in brightening the shell.

[0095] Exemplarily, the coating layer 3 in which the silicon oxide layer and the titanium oxide layer are sequentially arranged is a multilayer arrangement structure of (AB)n, wherein A is a silicon oxide layer, B is a titanium oxide layer, and n is an integer greater than or equal to 1. For example, the coating layer 3 can be formed by stacking a silicon oxide layer / a titanium oxide layer / a silicon oxide layer / a titanium oxide layer.

[0096] It can be understood that the coating layer 3 in which the silicon oxide layer and the titanium oxide layer are sequentially arranged can also be a multilayer arrangement structure of (ABBA)n, wherein A is a silicon oxide layer, B is a titanium oxide layer, and n is an integer greater than or equal to 1. For example, the coating layer 3 can also be formed by stacking a silicon oxide layer / a titanium oxide layer / a titanium oxide layer / a silicon oxide layer.

[0097] In an exemplary embodiment of the present disclosure, the thickness of the coating layer 3 is 100-180nm; the thickness of the ink layer 4 is 3-10μm. In this embodiment, it is necessary to control the thickness of the coating layer 3 to 100-180nm, and the thickness of the ink layer 4 to 3-10μm. When the thickness of the coating layer 3 or the ink layer 4 is too low, the desired brightening effect cannot be achieved. When the thickness of the coating layer 3 or the ink layer 4 is too high, the strength of the shell will decrease, and the desired mechanical properties cannot be achieved. Therefore, the coating layer 3 and the ink layer 4 within the above-mentioned thickness range can improve the highlight effect of the shell in this area without affecting the mechanical properties of the shell.

[0098] In an exemplary embodiment of the present disclosure, the thickness of the first glossy area 11 b is greater than or equal to that of the matte area 11 a.

[0099] In this embodiment, when the thickness of the first glossy area 11b is greater than or equal to the matte area 11a, the logo 2 located in the first glossy area 11b can be more prominently displayed. It can be understood that when the brightness of the logo 2 is sufficient, the thickness of the first glossy area 11b can also be less than the thickness of the matte area 11a. At this time, the logo 2 is embedded in the first surface 11, which can protect the logo 2 and prevent the logo 2 from being worn due to direct contact with the outside world.

[0100] In an exemplary embodiment of the present disclosure, the body 1 includes a transparent or translucent body.

[0101] In this embodiment, when the body 1 includes a transparent or translucent body, it is easier to show the brightening effect of the coating layer 3 and the ink layer 4. For example, the body 1 can be ordinary glass, microcrystalline glass, sapphire glass, transparent composite material, etc.

[0102] In an exemplary embodiment of the present disclosure, Figure 3As shown, a housing includes a body 1, a logo 2, a coating layer 3 and an ink layer 4; wherein the logo 2 is arranged on the first surface 11 of the body 1; the coating layer 3 and the ink layer 4 are stacked on the second surface 12 of the body 1; the second surface 12 is arranged opposite to the first surface 11; along the thickness direction of the body 1, the projection of the coating layer 3 and the ink layer 4 covers the projection of the area where the logo 2 is located. The body 1 is a transparent body, the first surface 11 of the body 1 includes a matte area 11a and a first glossy area 11b, and the logo 2 is arranged in the first glossy area 11b. The second surface 12 of the body 1 includes a second glossy area, and the coating layer 3 is arranged on the second glossy area.

[0103] In the present embodiment, since the main body 1 is a transparent body, when the coating layer 3 and the ink layer 4 are arranged on the second surface 12 of the main body 1, the logo 2 located on the first surface 11 can be brightened through the transparent medium of the main body 1; and, since the non-logo area of ​​the first surface 11 is a matte area 11a, the coating layer 3 and the ink layer 4 arranged on the second surface 12 cannot pass through the matte area 11a, thereby forming a light-matte visual effect on the first surface 11, thereby improving the appearance of the shell.

[0104] In an exemplary embodiment of the present disclosure, a method for processing a housing is provided, and the housing may be, for example, a housing of an electronic device. Figure 1 and Figure 4 As shown, the shell processing method in this embodiment includes:

[0105] S110 , providing a body 1 ; a logo 2 is disposed on a first surface 11 of the body 1 .

[0106] In this step, the raw material is selected and cut by a cutting machine to obtain a material plate suitable for the housing of an electronic device. The material plate is then polished to remove burrs, scratches and other defects on the surface of the material plate to obtain a body with a smooth surface and mirror gloss. The raw material can be transparent glass, and the body of this material has good optical properties, so as to obtain a richer appearance visual effect.

[0107] It should be understood that the logo 2 can be fixed on the first surface 11 of the body 1 by gluing or the like. Alternatively, the logo 2 can also be set in the body 1, for example, embedded in the body 1, and protrude from the first surface 11 relative to the body 1.

[0108] The logo 2 on the first surface 11 can be made by electroforming, stamping, electro-etching, chemical etching and other molding processes, which are not limited here. The logo 2 can be pre-made and fixed to the body 1, or the body 1 and the logo 2 can be made at the same time, which is not limited in the present disclosure.

[0109] S120, a coating layer 3 and an ink layer 4 are stacked on the second surface 12 of the body 1, wherein the second surface 12 may be arranged opposite to the first surface 11; that is, the body 1 may have two surfaces substantially parallel to each other, one of which is the first surface 11 and the other is the second surface 12, and a coating layer 3 and an ink layer 4 may be stacked on the second surface 12, specifically, along the thickness direction of the body 1, the projections of the coating layer 3 and the ink layer 4 cover the projection of the area where the logo 2 is located. That is, the projections of the coating layer 3 and the ink layer 4 in the thickness direction of the body 1 at least cover the projection of the logo in the thickness direction.

[0110] In this step, the coating layer 3 and the ink layer 4 are stacked on the second surface 12 of the body 1, which can brighten the area of ​​the body 1. The first surface 11 is the outer side of the body 1, that is, the side away from the electronic device body; the second surface 12 is the inner side of the body 1, that is, the side close to the electronic device body. It can be understood that when the coating layer 3 and the ink layer 4 are stacked in the logo area of ​​the first surface 11, the logo 2 can also be brightened; however, considering the service life of the coating layer 3 and the ink layer 4, in this embodiment, when the coating layer 3 and the ink layer 4 are arranged on the second surface 12 of the body 1, since the second surface 12 is located on the inner side of the body 1, the ink layer 4 can be prevented from directly contacting the outside world, thereby protecting the ink layer 4. When the body 1 is made of a transparent material, since the area where the ink layer 4 is located corresponds to the area where the logo 2 is located, the coating layer 3 and the ink layer 4 can pass through the body 1 and brighten the logo 2 located on the first surface 11.

[0111] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the shell processing method in this embodiment is a further limitation of step S120 in the above embodiment, including:

[0112] S210 , performing chemical plating on the second surface 12 of the body 1 to form a plating layer 3 .

[0113] In this step, the chemical plating method may be chemical reaction deposition, anodization, electroplating, etc. The purpose of the chemical plating in this embodiment is to form a colorless brightening coating layer on the second surface 12 to improve the brightness of the logo 2 .

[0114] Exemplarily, a vacuum evaporation coating method is used to deposit the evaporated particles of the target material on the second surface 12 of the body 1 to form a coating layer 3 containing the oxide of the target material. The vacuum evaporation coating method refers to a process method in which the target material is evaporated and vaporized by heating evaporation under vacuum conditions, and then the vaporized particles are splashed onto the surface of the substrate to condense into a film. In this embodiment, vacuum evaporation coating using conventional process conditions can achieve chemical coating, and the thickness of the formed coating layer 3 can be controlled to be 100-180nm.

[0115] The target material used in vacuum evaporation coating can be metal materials such as titanium, aluminum, silver, etc., or semiconductor materials such as silicon, germanium, or ceramic materials such as aluminum oxide, silicon nitride, etc. Considering the production cost and the color and brightness of the coating layer, when silicon target and / or titanium target are selected, a colorless brightening coating layer can be obtained.

[0116] It should be noted that the color and brightness of the film layer in this embodiment are characterized by the L value, a value and b value of the colorimeter. Among them, the L value is used to characterize the brightness of the color, and its numerical range is 0-100. The larger the L value, the brighter the measured color, and the smaller the L value, the darker the measured color. The a value is used to characterize the red-green degree of the color, +a represents reddish, and -a represents greenish. The b value is used to characterize the yellow-blue degree of the color, +b represents yellowish, and -b represents bluish.

[0117] For example, the coating layer 3 is formed by stacking a silicon dioxide layer and a titanium dioxide layer in sequence; since silicon dioxide and glass are similar in material, when the main body 1 contains glass material, the silicon dioxide layer has a good bonding force with the glass main body, and the coating layer 3 formed thereby has a good adhesion on the glass main body.

[0118] Exemplarily, when the thickness of the coating layer 3 is 120 nm, the L value is 70, and the ab value is close to 0, a colorless brightening coating layer can be obtained.

[0119] After testing, when the thickness of the coating layer 3 is 300nm, the L value is 80, but its strength is reduced by 70% compared with the above coating layer 3. Therefore, when the thickness of the coating layer 3 is 100-180nm, it has better optical and mechanical properties.

[0120] S220 , coating mirror silver ink on the coating layer 3 to form an ink layer 4 .

[0121] In this step, the purpose of coating the coating layer 3 with mirror silver ink is to form a silver mirror effect on the coating layer 3, wherein the "mirror effect" refers to a mirror effect obtained from the front side of a transparent material by printing on the back side of the transparent material; in this embodiment, a silver metal mirror effect can be obtained by coating the second surface 12 of the transparent body with mirror silver ink to improve the glossiness of the logo 2 located on the first surface 11.

[0122] In order to increase the brightness of the ink layer 4, a high-gloss mirror silver ink may be selected. After the high-gloss mirror silver ink is applied, the coating has a high-gloss effect, so as to increase the brightness and glossiness of the logo 2. It should be noted that "high-gloss" in this embodiment means that the L value is greater than 60.

[0123] Exemplarily, the implementation process of screen printing the mirror silver ink on the coating layer 3 to form the ink layer 4 in step S220 is as follows:

[0124] Mirror silver ink is coated on the coating layer 3 corresponding to the area where the logo 2 is located, and baked at a temperature of 140-160° C. for 50-70 minutes to form an ink layer 4.

[0125] For example, the mass percentage of each component of the high-gloss mirror silver ink to the mass percentage of the high-gloss mirror silver ink is expressed as follows:

[0126] Metal powder 50-60%, resin 5-15%, ether solvent 15-25% and ketone solvent 10-20%.

[0127] The metal powder may be aluminum powder. If there is no requirement on the color of the ink layer, copper powder may be used as the metal powder to obtain a high-gloss mirror gold ink, in which case the ink layer may appear golden.

[0128] The resin is used as a binder in the ink to make the metal powder disperse evenly, and can be, for example, a combination of one or more of ethyl cellulose, nitrocellulose, polyvinyl acetate, polyamide resin, and acrylic resin.

[0129] Ether solvents and ketone solvents are organic solvents in inks, which can dissolve and disperse resins and metal powders. For example, the ether solvent can be one or a combination of propylene glycol methyl ether and ethylene glycol butyl ether. The ketone solvent can be isophorone.

[0130] Exemplarily, the mass percentage of each component of the high-gloss mirror silver ink to the mass percentage of the high-gloss mirror silver ink is expressed as follows: 50-60% of flaky aluminum powder, 5-15% of resin, 15-25% of propylene glycol methyl ether and 10-20% of isophorone.

[0131] Furthermore, the mass percentage of each component of the high-gloss mirror silver ink to the mass percentage of the high-gloss mirror silver ink is expressed as follows: 55% of flaky aluminum powder, 10% of resin, 20% of propylene glycol methyl ether and 15% of isophorone.

[0132] In an exemplary embodiment of the present disclosure, Figure 1 and Figure 5 As shown, the processing method of the shell in this embodiment includes:

[0133] S310 , providing a body 1 ; a logo 2 is disposed on a first surface 11 of the body 1 .

[0134] This step is the same as the implementation of step S110 in the above embodiment, and will not be described again here.

[0135] S320 , forming a matte area 11 a and a first glossy area 11 b on the first surface 11 of the body 1 , wherein the first glossy area 11 a is provided with a logo 2 .

[0136] In this step, the first surface 11 forms a matte area 11a and a first glossy area 11b, and the logo 2 is arranged in the first glossy area 11b, so that the shell obtained has a glossy and matte body visual effect.

[0137] S330, stacking a coating layer 3 and an ink layer 4 on the second surface 12 of the main body 1, wherein the second surface 12 is arranged opposite to the first surface 11, and along the thickness direction of the main body 1, the projections of the coating layer 3 and the ink layer 4 cover the projection of the area where the logo 2 is located.

[0138] This step is the same as the implementation of step S120 in the above embodiment, and will not be described again here.

[0139] In an exemplary embodiment of the present disclosure, Figure 1 As shown, the processing method of the shell in this embodiment is a further limitation of step S320 in the above embodiment, including:

[0140] S410, providing a first protective layer on the first surface 11 of the body 1 at the area where the mark 2 is located, to obtain a body provided with the first protective layer.

[0141] In this step, a first protective layer is provided at the area where the logo 2 is located on the first surface 11 of the body 1 , so as to protect the area where the logo 2 is located, thereby ensuring that the surface of the area where the logo 2 is located is a smooth surface.

[0142] The first protective layer may be ink. The ink in this embodiment needs to protect the area where the logo 2 is located to prevent corrosion of the first protective layer by subsequent treatment. For example, during subsequent treatment, an acidic reagent such as hydrofluoric acid needs to be used to roughen the first surface of the body. At this time, the ink needs to be acid-resistant ink to resist corrosion of the first protective layer formed by the ink by hydrofluoric acid.

[0143] Exemplarily, the percentage of the mass of each component of the ink to the total mass of the ink is expressed as follows:

[0144] Colorant 40-50%, binder 10-20%, silane coupling agent 5-15% and organic solvent 20-40%.

[0145] The colorant is a pigment with certain color covering ability and corrosion resistance, which can protect the area where the mark 2 is located and avoid corrosion of the protective layer by subsequent treatment.

[0146] The adhesive can improve the adhesion of the first protective layer to the body 1, thereby preventing the first protective layer from falling off and causing damage to the area where the logo is located during subsequent processing.

[0147] Silane coupling agents can improve the bonding properties between colorants and adhesives and increase the uniformity of dispersion of the components in inks.

[0148] As the solvent of the ink system, the organic solvent plays a dispersing role on other components.

[0149] The percentage of the mass of each component of the ink to the total mass of the ink is expressed as follows:

[0150] Colorant 40-50%, bisphenol A diglycidyl ether 10-20%, 3-glycidyloxypropyltrimethoxysilane 5-15%, ethylene glycol butyl ether 15-25%, diethylene glycol butyl ether 2-8% and tetramethylbenzene 3-7%.

[0151] Exemplarily, the percentage of the mass of each component of the ink to the total mass of the ink is expressed as follows:

[0152] Colorant 45%, bisphenol A diglycidyl ether 15%, 3-glycidyloxypropyltrimethoxysilane 10%, ethylene glycol butyl ether 20%, diethylene glycol butyl ether 5% and tetramethylbenzene 5%.

[0153] It can be understood that the content of each component of the ink can also be other values ​​within the above range. For example, the percentage of the mass of each component of the ink to the total mass of the ink is expressed as follows:

[0154] Colorant 40%, bisphenol A diglycidyl ether 10%, 3-glycidyloxypropyltrimethoxysilane 15%, ethylene glycol butyl ether 25%, diethylene glycol butyl ether 5% and tetramethylbenzene 5%.

[0155] Alternatively, the percentage of the mass of each component of the ink to the total mass of the ink is expressed as follows:

[0156] Colorant 50%, bisphenol A diglycidyl ether 20%, 3-glycidyloxypropyltrimethoxysilane 5%, ethylene glycol butyl ether 15%, diethylene glycol butyl ether 5% and tetramethylbenzene 5%.

[0157] The above ink is mixed with a diluent and a hardener in a mass ratio of 100:5-15:5-15 before use.

[0158] Exemplarily, the ink is mixed with a diluent and a hardener in a mass ratio of 100:10:10 before use.

[0159] It is understandable that the mass ratio of ink, diluent and hardener can also be other ratios within the above range, for example, the mass ratio of ink, diluent and hardener is 100:5:5, or the mass ratio of ink, diluent and hardener is 100:15:15.

[0160] Exemplarily, the ink is applied to the area where the logo 2 is located on the first surface 11 of the body 1, and baked at a temperature of 140-160°C for 50-70 minutes to form a first protective layer.

[0161] S420 , roughening the first surface 11 of the body provided with the first protective layer to obtain a roughened body, so as to form a matte area 11 a on the first surface 11 .

[0162] In this step, the first surface 11 of the body provided with the first protective layer is roughened to form a matte area 11a on the first surface 11 of the body 1. Since the first protective layer is provided in the area where the logo 2 is located, the surface of the logo area is glossy.

[0163] In this embodiment, the first surface 11 of the main body provided with the first protective layer can be subjected to anti-glare (AG) treatment to form a matte area 11a on the first surface 11. AG stands for Anti-Glare, and AG treatment includes spraying AG process, coating AG process, and chemical etching AG process. The specific process method can be adjusted according to actual conditions. After the first surface 11 of the main body 1 is roughened, the surface haze of the matte area 11a formed is 40-100%, and the roughness is (0.25-3.5)×10 3 nm is enough.

[0164] S430 , removing the first protective layer on the roughened body to obtain a first smooth surface area 11 b where the logo 2 is located.

[0165] In this step, the first protective layer is removed to reveal the glossy surface of the area where the logo 2 is located, thereby forming a glossy and matte homogeneous effect. At this time, the glossy effect of the area where the logo 2 is located depends on the material of the body 1 itself.

[0166] Exemplarily, the roughened body is immersed in a cleaning agent for a preset time to remove the first protective layer, so as to obtain the first smooth surface area 11b where the logo 2 is located.

[0167] The type of cleaning agent needs to match the type of ink used for the first protective layer; for example, if the ink of the first protective layer is acid-resistant ink, the cleaning agent needs to be an alkaline cleaning agent to remove the first protective layer.

[0168] In an exemplary embodiment of the present disclosure, Figure 1 and Figure 6 As shown, the processing method of the shell in this embodiment includes:

[0169] S510 , providing a body 1 ; and providing a logo 2 on a first surface 11 of the body 1 .

[0170] This step is the same as the implementation of step S110 in the above embodiment, and will not be described again here.

[0171] S520 , disposing a second protective layer on the second surface 12 of the body 1 to form a second light surface area on the second surface 12 .

[0172] In this step, a second protective layer is provided on the second surface 12 of the body 1 to protect the second surface 12 and ensure that the second surface 12 is a smooth surface.

[0173] This step is the same as the ink composition and dosage and the process conditions for coating the ink in step S410 in the above embodiment, and will not be described in detail here.

[0178] S560, stacking a coating layer 3 and an ink layer 4 on the second smooth surface area of ​​the second surface 12 of the body 1, and along the thickness direction of the body 1, the projections of the coating layer 3 and the ink layer 4 cover the projection of the area where the logo 2 is located.

[0179] This step is the same as the implementation of step S120 in the above embodiment, and will not be described again here.

[0180] According to the method of this embodiment, a second protective layer and a first protective layer are respectively arranged on the second surface 12 and the first surface 11 of the main body 1 to form a second polished area and a first polished area 11b, thereby avoiding surface damage to the second polished area and the first polished area 11b caused by subsequent surface roughening treatment; after the coating layer 3 and the ink layer 4 are sequentially stacked on the second polished area, the logo 2 located at the first polished area 11b can be brightened through the second polished area and the first polished area 11b, thereby improving the aesthetics of the shell appearance.

[0181] In an exemplary embodiment of the present disclosure, Figure 2 and Figure 7 As shown, the processing method of the shell in this embodiment includes:

[0182] S610 , providing a body 1 ; and setting a logo 2 on the first surface 11 of the body 1 .

[0188] S660, placing the matte homogeneous body in a strengthening furnace for strengthening treatment.

[0191] S680 , along the thickness direction of the body 1 , apply mirror silver ink on the coating layer 3 at the projection position of the logo 2 to form an ink layer 4 , thereby obtaining a shell.

[0192] The implementation of steps S670 to S680 in this embodiment is the same as that of steps S210 to S220 in the above embodiment, and will not be repeated here.

[0193] S690, attaching a decorative film to the surface of the shell and removing bubbles on the film; filling the concave edge of the shell with ink and removing the overflowed ink to obtain a finished shell.

[0194] In this step, a decorative film can be attached to the surface of the shell as needed, and after removing bubbles, repairing the edge of the shell, and removing overflowed ink, the aesthetics of the finished shell can be further improved.

[0195] The method of this embodiment strengthens the matte body before coating, which can improve the strength of the matte body and further ensure the service life of the matte body. In addition, the matte body after strengthening has an explosion-proof effect, which is beneficial to improve the safety of the shell.

[0196] In an exemplary embodiment of the present disclosure, an electronic device is provided, and the electronic device is, for example, a mobile phone, a laptop computer, a tablet computer, and a wearable device.

[0197] The electronic device comprises the shell, and the shell can achieve a light-matte homogeneous effect, thereby improving the aesthetics of the electronic device.

[0198] The processing method of the shell provided by the present disclosure is described in detail below in combination with specific preparation examples and embodiments.

[0199] Preparation Example

[0200] Preparation Example 1: Mix and stir 45g of colorant, 15g of bisphenol A diglycidyl ether, 10g of 3-glycidyloxypropyltrimethoxysilane, 20g of ethylene glycol butyl ether, 5g of diethylene glycol butyl ether and 5g of tetramethylbenzene to obtain an acid-resistant ink, which is used to coat the logo area on the first surface of the body and the second surface to protect the area, thereby forming a first glossy area and a second glossy area.

[0201] Preparation Example 2: Take 55g of flaky aluminum powder, 10g of resin, 20g of propylene glycol methyl ether and 15g of isophorone, mix and stir evenly to obtain a high-gloss mirror silver ink, which is used to apply on the coating layer corresponding to the area where the logo is located to form an ink layer.

[0202] Example

[0203] It should be noted that the acid-resistant ink in the following examples is prepared by the above-mentioned Preparation Example 1, and the high-gloss mirror silver ink is prepared by the above-mentioned Preparation Example 2.

[0204] Embodiment 1: A method for processing a shell, such as Figure 1 As shown, including:

[0205] (1) Transparent glass is selected as the raw material, and the transparent glass is cut and polished to obtain a body 1 with a smooth surface and mirror gloss. The body 1 has a first surface 11 and a second surface 12 arranged opposite to each other, the first surface 11 is the back side of the body 1 (relative to the outside of the electronic device), and the second surface 12 is the front side of the body 1 (relative to the inside of the electronic device), and a logo 2 is arranged on the first surface 12 of the body 1;

[0206] (2) Acid-resistant ink, a diluent, and a hardener are mixed in a mass ratio of 10:1:1 to obtain a mixed acid-resistant ink; then the acid-resistant ink is screen-printed on the second surface 12 of the body 1, and baked at a temperature of 150° C. for 60 minutes to form a second protective layer with a thickness of 10 μm;

[0207] (3) printing the mixed acid-resistant ink on the area where the logo 2 is located on the first surface 11 of the body 1, and baking it at 150° C. for 60 minutes to form a first protective layer with a thickness of 10 μm;

[0208] (4) The main body provided with the first protective layer and the second protective layer is subjected to AG treatment at the etched sand line to obtain a roughened main body, so as to form a matte area 11a on the first surface 11, and the haze of the matte area 11a is 60% and the roughness is 2.0×10 3 nm;

[0209] (5) Using an alkaline cleaning agent to clean the acid-resistant ink on the body 1 to remove the first protective layer and the second protective layer. At this time, the logo 2 area on the first surface 11 of the body 1 is the first glossy area 11b, and the second surface 12 of the body 1 is the second glossy area, so as to obtain a matte homogeneous body;

[0210] (6) placing the matte homogeneous body in a strengthening furnace for strengthening treatment to improve the strength of the matte homogeneous body;

[0211] (7) chemically coating the second polished surface area of ​​the matte homogeneous body after strengthening treatment, using vacuum evaporation coating method, selecting silicon target and titanium target, and sequentially stacking silicon dioxide layer / titanium dioxide layer / silicon dioxide layer in the second polished surface area to obtain a coating layer 3 with a thickness of 120 nm; the L value of the coating layer is 70, and the ab value is close to 0;

[0212] (8) Screen-printing a high-gloss mirror silver ink at the projection position of the logo 2 on the coating layer 3 along the thickness direction of the body 1, and baking at a temperature of 150° C. for 60 min to form an ink layer 4 with a thickness of 5 μm to obtain a shell;

[0213] (9) A decorative film is attached to the front of the shell, and bubbles on the film are removed; the concave edge of the shell attached with the film is filled with ink, and the overflowed ink is removed to obtain a finished shell.

[0214] The performance test results of the shell prepared by the method of Example 1 are as follows:

[0215] UV test 96h color difference △E<2;

[0216] The 100-grid test grade is 4B;

[0217] Strength 4PB>400MPa.

[0218] The color difference ΔE represents the comprehensive color difference between objects. When ΔE<2, it means that the object has a very slight color deviation, but it is basically indistinguishable to the naked eye. The color difference ΔE of the UV test of Example 1 for 96 hours is less than 2, indicating that the shell has a very slight color deviation before and after 96 hours of ultraviolet irradiation, which meets the product quality requirements.

[0219] The 100-grid test is a method for testing the adhesion of paint films. According to international standards, it can be divided into 6 levels, namely 0B, 1B, 2B, 3B, 4B, and 5B. The larger the level (number), the better the adhesion of the paint film; 4B means that small pieces of paint fall off at the intersection of the lines, and the total area of ​​the paint fall off is less than 5%. The 100-grid test level of Example 1 is 4B, indicating that the paint film of the shell of Example 1 has good adhesion.

[0220] Strength 4PB is a performance parameter of glass, which indicates a four-point bending test of glass. The strength 4PB of Example 1 is greater than 400 MPa, indicating that the housing of Example 1 has a relatively high mechanical strength.

[0221] In summary, the shell prepared by the method disclosed in the present invention not only has a matte and solid visual effect, but also can make the logo area achieve a high-brightness visual effect; and the obtained shell also has good mechanical properties and better comprehensive performance.

[0222] In an exemplary embodiment of the present disclosure, Figure 8 As shown, a plate-like structure 5 is provided, comprising a first fiber layer 51, a second fiber layer 52, and a third fiber layer 53 stacked in layers; the fiber types in any two adjacent fiber layers are different. The plate-like structure 5 provided in this embodiment can be used for a housing of an electronic device, or for a backplane of an electronic device. The electronic device can be a mobile phone, a computer, a wearable device, etc.

[0223] In this embodiment, the plate-like structure 5 is formed by stacking, and since the main raw material of the plate-like structure is fiber, it has the advantage of being light in weight.

[0224] In an exemplary embodiment of the present disclosure, the fiber types in the first fiber layer 51 and the third fiber layer 53 are the same.

[0225] In an exemplary embodiment of the present disclosure, the second fiber layer 52 includes, by mass percentage:

[0226] Continuous inorganic fibers 50-70% and resin 30-50%.

[0227] In this embodiment, the continuous inorganic fibers in the second fiber layer 52 can provide good mechanical properties, and the resin can provide good molding properties, which is conducive to the second fiber layer 52 forming a uniform and dense structure and improving the rigidity of the second fiber layer 52.

[0228] Exemplarily, the continuous inorganic fibers include a combination of one or more of continuous ceramic fibers, continuous quartz fibers, and continuous silicon fibers. The continuous inorganic fibers can provide a higher modulus for the second fiber layer 52, thereby improving the overall modulus and rigidity of the plate-like structure 5.

[0229] Exemplarily, the resin includes a combination of one or more of polyester resin, epoxy resin, phenolic resin, and bismaleimide resin.

[0230] The polyester resin, epoxy resin, phenolic resin and bismaleimide resin in this embodiment have excellent bonding properties, and after being mixed with continuous inorganic fibers, they can form a uniform and dense fiber structure; in addition, the polyester resin, epoxy resin, phenolic resin and bismaleimide resin also have good mechanical properties, and the second fiber layer 52 obtained by combining them with continuous inorganic fibers has high strength and modulus, thereby playing the role of skeleton support for the plate-like structure.

[0231] In an exemplary embodiment of the present disclosure, the first fiber layer 51 and / or the third fiber layer 53 includes, by mass percentage:

[0232] Aramid fiber 50-70% and resin 30-50%.

[0233] In this embodiment, aramid fiber has the advantages of high toughness and high impact resistance, and can be provided with a personalized appearance texture through a weaving process. The first fiber layer 51 and / or the third fiber layer 53 made of aramid fiber as the base fiber of the first fiber layer 51 and / or the third fiber layer 53 not only have excellent mechanical properties, but also have good appearance performance.

[0234] It is understandable that the aramid fibers in the first fiber layer 51 and / or the third fiber layer 53 may also be replaced by other high-performance fibers with high strength, high modulus, etc., for example, ultra-high molecular weight polyethylene fibers, ultra-high molecular weight polyvinyl alcohol fibers, etc.

[0235] In this embodiment, the resin in the first fiber layer 51 and / or the third fiber layer 53 also plays a bonding role, so as to form a dense fiber structure with the aramid fiber. For example, the resin in the first fiber layer 51 and / or the third fiber layer 53 may include a combination of one or more of polyester resin, epoxy resin, phenolic resin, and bismaleimide resin.

[0236] In addition, it should be understood that the first fiber layer 51, the second fiber layer 52 and the third fiber layer 53 can all be formed by stacking multiple fiberboards, and the multiple fiberboards in each fiber layer can be made of the same material, or of different materials.

[0237] In some embodiments, the first fiber layer 51 can be formed by stacking a preset number of fiberboards, and each layer of fiberboard can be made of fibers with a specific arrangement and orientation. It should be understood that the fiberboard has warps and wefts. For a specific fiberboard, all warps can be arranged parallel to each other, all wefts can be arranged parallel to each other, and the warps and wefts can be oriented to form a preset orientation angle with each other. For example, the second preset angle between the warps and wefts in the fiberboard is set within the range of 30-90 degrees. For example, the second preset angle between the warps and wefts in the fiberboard can be set to 40 degrees, 60 degrees, 75 degrees, 80 degrees or 90 degrees, which can make the structure of the fiberboard more stable, so that it has a higher stress tolerance in both the warp direction and the weft direction, and further enhances the strength and structural stability of the plate-like structure 5 provided by the present disclosure.

[0238] Among them, multiple layers of fiberboards can be stacked on each other. In the present disclosure, the preset number of fiberboard layers is limited to 2 to 6 layers. For example, the preset number of fiberboard layers can be 2 layers, 3 layers, 4 layers, 5 layers, and 6 layers. By changing the stacking angles between the fiberboards and performing stacking optimization, an ultra-thin shell thickness can be achieved while ensuring the shell strength. The shell can withstand stress from all directions, so that the overall force strength of the shell is high enough and the structure is stable enough under the complex integrated shape.

[0239] For example, the first preset angle between adjacent fiberboards can be selected in combination with the number of fiberboard layers, the shape of the board, the force direction and the degree of force. For example, the first preset angle can be in the range of 15 to 75 degrees. In an exemplary example of the present disclosure, the shell includes 4 layers of fiberboards, and the stacking angle between each fiberboard, that is, the warp and / or weft between adjacent fiberboards is "0 degrees / 45 degrees / 0 degrees / 45 degrees", and the first preset angle is 45 degrees. Or "0 degrees / 45 degrees / 45 degrees / 0 degrees", the first preset angle is 45 degrees and 0 degrees. Or the warp and / or weft between adjacent fiberboards is "0 degrees / 60 degrees / 60 degrees / 0 degrees", the first preset angle is 60 degrees and 0 degrees. Or "0 degrees / 60 degrees / 0 degrees / 60 degrees", the first preset angle is 60 degrees. Or the warp and / or weft between adjacent fiberboards is "0 degrees / 45 degrees / 60 degrees / 15 degrees", and the first preset angle includes 45 degrees, 15 degrees and 60 degrees. The first preset angles between adjacent fiberboards may be the same or different and may be flexibly selected according to actual needs, and the present disclosure does not limit this.

[0240] Similarly, for the arrangement of the second fiber layer 52 and the third fiber layer 53 , reference may be made to the description of the first fiber layer 51 , and the present disclosure is not limited thereto.

[0241] In an exemplary embodiment of the present disclosure, Figure 8 As shown, a plate-like structure 5 is provided, comprising a first fiber layer 51, a second fiber layer 52, and a third fiber layer 53 which are stacked;

[0242] In terms of mass percentage, the second fiber layer 52 includes: 50-70% continuous ceramic fibers and 30-50% resin;

[0243] In terms of mass percentage, the first fiber layer 51 and / or the third fiber layer 53 includes: 50-70% aramid fiber and 30-50% resin.

[0244] In this embodiment, the second fiber layer 52 provides a skeleton support and has good modulus and rigidity; the first fiber layer 51 and the third fiber layer 53 are respectively located on both sides of the second fiber layer 52, have good toughness and impact resistance, and can also provide a personalized appearance visual effect. When the plate-like structure obtained is used for the housing or backplane of an electronic device, it can have the advantages of both mechanical properties and appearance performance, and has good comprehensive performance.

[0245] In an exemplary embodiment of the present disclosure, the thickness of the plate-like structure 5 is 0.05-0.50 mm.

[0246] In this embodiment, when the thickness of the plate-like structure 5 is maintained at 0.05-0.50 mm, it has the characteristics of being light and thin, and the housing or back panel of the electronic device prepared by the plate-like structure 5 meets the requirements of lightweight products.

[0247] Exemplarily, the thickness ratio of the first fiber layer 51 , the second fiber layer 52 , and the third fiber layer 53 is 1-3:1:1-3.

[0248] In this embodiment, the second fiber layer 52 is used as a skeleton support material, and its thickness can be the same as or slightly lower than the thickness of the first fiber layer 51 or the second fiber layer 53 , so that the obtained plate-like structure 5 has better mechanical properties.

[0249] Exemplarily, the thickness of the first fiber layer 51 is 0.1-0.3 mm;

[0250] The thickness of the second fiber layer 52 is 0.05-0.15 mm;

[0251] The thickness of the third fiber layer 53 is 0.1-0.3 mm.

[0252] In this embodiment, by limiting the thickness of each fiber layer, the rigidity and toughness of the material can be balanced, thereby controlling the overall mechanical properties of the plate-like structure 5 .
