[0076] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0077] In related technologies, to meet diverse needs and enhance the competitiveness of electronic devices, manufacturers are dedicated to developing various electronic device housings with different aesthetic effects. Among these, a dual-tone (glossy and matte) housing refers to a housing that simultaneously displays both glossy and matte finishes. For example, the markings (such as the logo) area of ​​the housing can be glossy, while other areas can be matte. This not only gives the overall housing a sophisticated, frosted, and anti-glare texture but also highlights the markings, thereby improving the product's visual impact and premium feel.

[0078] In the related technologies, the brightness and gloss of the bright areas in the matte-gloss integrated housing are limited by the brightness and gloss of the housing itself, resulting in poor visual effect. Therefore, this also restricts the development of matte-gloss integrated housings.

[0079] Based on this, the present disclosure provides a housing that includes a 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 body, the gloss of that area of ​​the housing can be improved. Furthermore, the coating layer and the ink layer can make the gloss effect of the housing no longer limited by the appearance of the body itself, thereby providing a richer visual effect for the housing.

[0080] In an exemplary embodiment of this 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] Mark 2 is set on the first surface 11 of the main 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 disposed 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 mark 2 is located.

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

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

[0086] Marker 2 is set in the first smooth surface area 11b.

[0087] The identifier 2 can be a pattern, design, number, or trademark that needs to be highlighted on the casing. In this embodiment, the identifier 2 is set in the first glossy area 11b of the first surface 11, and the other areas of the first surface 11 are matte areas 11a. This allows the identifier area on the casing to have a glossy effect, while the other areas have a matte effect, thus creating a glossy and matte finish.

[0088] The positions and areas of the first glossy region 11b and the matte region 11a on the first surface 11 can be set as needed and are not limited here. For example, as shown... Figure 1 As shown, the first surface 11 includes a first glossy area 11b and two matte areas 11a located on both sides of the first glossy area 11b. 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 effect, and the marking area can be highlighted, thereby enhancing the visual impact and high-end texture of the shell.

[0089] In an exemplary embodiment of this disclosure, the second surface 12 of the body 1 includes a second glossy region, and a coating layer 3 is disposed on the second glossy region. In this embodiment, disposing the coating layer 3 on the second glossy region is beneficial for improving the brightness of that region of the housing. For example, as... Figure 1As shown, the entire second surface 12 is a second smooth surface area. The coating layer 3 can be directly applied to the second smooth surface area, so that the second smooth surface area is completely covered by the coating layer 3.

[0090] Among them, such as Figure 1 As shown, when the second glossy area is completely covered by the coating layer 3, the ink layer 4 can be directly applied to the coating layer 3, so that the coating layer 3 is completely covered by the ink layer 4. It is understandable that when the casing needs to display a glossy effect not only in the area where the mark 2 is located, but also in other areas, such as... Figure 2 As shown, the ink layer 4 is only disposed on the coating layer 3 at the projection position of the mark 2. For example, in order to enrich the appearance of the shell, a decorative film needs to be attached to the surface of the manufactured glossy and matte shell. In this case, the ink layer 4 is only disposed on the coating layer 3 at the projection position of the mark 2, which can make the mark area present a bright effect and avoid the ink layer 4 from blocking the decorative film.

[0091] Understandably, in order to reduce target material loss and decrease the coating area, the coating layer 3 can also be disposed on a portion of the second smooth surface area. For example... 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 glossy area at the projection position of the mark 2.

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

[0093] For example, the coating layer 3 can 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 disposed sequentially. In this embodiment, when the coating layer 3 is made of silicon oxide layer and titanium oxide layer disposed sequentially, the resulting coating layer 3 not only has good chemical stability, but also good brightness enhancement transparency, which can enhance the brightness of the shell.

[0095] For example, the coating layer 3, in which silicon oxide layers and titanium oxide layers are sequentially disposed, has a multilayer arrangement of (AB)n, where A is the silicon oxide layer, B is the 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 silicon oxide layers / titanium oxide layers / silicon oxide layers / titanium oxide layers.

[0096] Understandably, the coating layer 3, in which silicon oxide layers and titanium oxide layers are sequentially disposed, can also be a multilayer arrangement structure of (ABBA)n, where A is the silicon oxide layer, B is the 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 silicon oxide layers / titanium oxide layers / titanium oxide layers / silicon oxide layers.

[0097] In an exemplary embodiment of this disclosure, the thickness of the coating layer 3 is 100-180 nm; the thickness of the ink layer 4 is 3-10 μm. In this embodiment, the thickness of the coating layer 3 needs to be controlled within 100-180 nm, and the thickness of the ink layer 4 needs to be controlled within 3-10 μm. 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 required mechanical properties cannot be achieved. Therefore, within the above-mentioned thickness range, the coating layer 3 and the ink layer 4 can improve the high-brightness effect of the shell in this area without affecting the mechanical properties of the shell.

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

[0099] In this embodiment, when the thickness of the first glossy area 11b is greater than or equal to that of the matte area 11a, the mark 2 located in the first glossy area 11b can be more prominently displayed. Understandably, when the brightness of the mark 2 is sufficient, the thickness of the first glossy area 11b can also be less than the thickness of the matte area 11a. In this case, the mark 2 is embedded in the first surface 11, which can protect the mark 2 and prevent it from being directly contacted by the outside world and causing wear.

[0100] In an exemplary embodiment of this disclosure, body 1 includes a transparent or semi-transparent body.

[0101] In this embodiment, when the body 1 includes a transparent or semi-transparent body, it is easier to showcase 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 this disclosure, such as 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 disposed on a first surface 11 of the body 1; the coating layer 3 and the ink layer 4 are stacked on a second surface 12 of the body 1; the second surface 12 is disposed opposite to the first surface 11; 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. The body 1 is a transparent body, and the first surface 11 of the body 1 includes a matte area 11a and a first glossy area 11b, with the logo 2 disposed on the first glossy area 11b. 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.

[0103] In this embodiment, since the body 1 is a transparent body, when the coating layer 3 and the ink layer 4 are disposed on the second surface 12 of the body 1, the mark 2 located on the first surface 11 can be brightened through the transparent medium of the body 1; and since the non-marking area of ​​the first surface 11 is a matte area 11a, the coating layer 3 and the ink layer 4 disposed on the second surface 12 cannot be transmitted through the matte area 11a, thereby forming a visual effect of both gloss and matte on the first surface 11, thereby improving the appearance aesthetics of the housing.

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

[0105] S110, Provide a body 1; A mark 2 is provided on the first surface 11 of the body 1.

[0106] In this step, raw materials are selected and cut using a cutting machine to obtain a sheet material suitable for the electronic device housing. The sheet material is then polished to remove burrs, scratches, and other defects from its surface, resulting in a smooth, mirror-like finish. The raw material can be transparent glass, which possesses excellent optical properties, allowing for a richer visual appearance.

[0107] It should be understood that the mark 2 can be fixed to the first surface 11 of the body 1 by means of adhesive or the like. Alternatively, the mark 2 can also be disposed 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 mark 2 on the first surface 11 can be made using forming processes such as electroforming, stamping, electro-etching, and chemical etching, and is not limited thereto. The mark 2 can be pre-manufactured and fixed to the body 1, or the body 1 and the mark 2 can be manufactured simultaneously, and this disclosure does not limit this.

[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 disposed opposite to the first surface 11; that is, the body 1 may have two substantially parallel surfaces, one of which is the first surface 11 and the other is the second surface 12. The coating layer 3 and the 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 mark 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 mark 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 this area of ​​the body 1. The first surface 11 is the outer side of the body 1, i.e., the side away from the main body of the electronic device; the second surface 12 is the inner side of the body 1, i.e., the side closer to the main body of the electronic device. Understandably, when the coating layer 3 and the ink layer 4 are stacked on the marking area of ​​the first surface 11, they can also brighten the marking 2; however, considering the lifespan of the coating layer 3 and the ink layer 4, in this embodiment, when the coating layer 3 and the ink layer 4 are placed on the second surface 12 of the body 1, since the second surface 12 is located inside the body 1, direct contact between the ink layer 4 and the outside world can be avoided, thus 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 marking 2 is located, the coating layer 3 and the ink layer 4 can be transmitted through the body 1, thus brightening the marking 2 located on the first surface 11.

[0111] In an exemplary embodiment of this disclosure, as 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. A chemical coating is applied to the second surface 12 of the body 1 to form a coating layer 3.

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

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

[0115] The target material used in vacuum evaporation coating can be a metallic material such as titanium, aluminum, or silver, a semiconductor material such as silicon or germanium, or a ceramic material such as alumina or silicon nitride. Considering production costs and the color and brightness of the coating layer, using silicon and / or titanium targets can yield a colorless and brightening coating layer.

[0116] It should be noted that the color and brightness of the film layer in this embodiment are characterized using the L, a, and b values ​​of a colorimeter. The L value characterizes the lightness or darkness of a color, ranging from 0 to 100. A larger L value indicates a brighter color, and a smaller L value indicates a darker color. The a value characterizes the red-green hue of the color, with +a representing a reddish tint and -a representing a greenish tint. The b value characterizes the yellow-blue hue of the color, with +b representing a yellowish tint and -b representing a bluish tint.

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

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

[0119] Tests showed that when the thickness of coating layer 3 was 300 nm, the L value was 80, but its strength decreased by 70% compared to the aforementioned coating layer 3. Therefore, when the thickness of coating layer 3 was 100-180 nm, it exhibited better optical and mechanical properties.

[0120] S220. Apply mirror silver ink to the coating layer 3 to form 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. The "mirror effect" refers to the mirror effect obtained from the front of the transparent material by printing on the reverse side. In this embodiment, a silver metallic mirror effect can be obtained by coating the second surface 12 of the transparent body with mirror silver ink to improve the gloss of the mark 2 located on the first surface 11.

[0122] To enhance the brightness of ink layer 4, a high-gloss mirror silver ink can be selected. After applying the high-gloss mirror silver ink, the coating exhibits a high-gloss effect, thereby simultaneously increasing the brightness and gloss of the mark 2. It should be noted that in this embodiment, "high-gloss" refers to an L value greater than 60.

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

[0124] Apply mirror silver ink to the coating layer 3 corresponding to the area where mark 2 is located, and bake at 140-160℃ for 50-70 minutes to form ink layer 4.

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

[0126] The composition includes 50-60% metal powder, 5-15% resin, 15-25% ether solvents, and 10-20% ketone solvents.

[0127] The metal powder can be aluminum powder. If there are no requirements for the color of the ink layer, copper powder can also be used as the metal powder to obtain a high-gloss mirror gold ink, in which case the ink layer will appear gold.

[0128] Resin, as a binder in ink, enables the metal powder to be dispersed evenly. For example, it can be one or more of ethyl cellulose, nitrocellulose, polyvinyl acetate, polyamide resin, and acrylic resin.

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

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

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

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

[0133] S310, Provide a body 1; A mark 2 is provided on the first surface 11 of the body 1.

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

[0135] S320, A matte region 11a and a glossy region 11b are formed on the first surface 11 of the body 1, wherein the glossy region 11a is provided with a mark 2.

[0136] In this step, the first surface 11 forms a matte area 11a and a first glossy area 11b, and the mark 2 is placed in the first glossy area 11b, thereby giving the housing a visual effect of both glossy and matte finish.

[0137] S330. 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 is disposed opposite to the first surface 11, and the projection of the coating layer 3 and the ink layer 4 covers the projection of the area where the mark 2 is located along the thickness direction of the body 1.

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

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

[0140] S410. A first protective layer is provided in the area where the mark 2 is located on the first surface 11 of the body 1, thereby obtaining a body with the first protective layer provided.

[0141] In this step, a first protective layer is provided on the area where the mark 2 is located on the first surface 11 of the body 1, which can protect the area where the mark 2 is located and ensure that the surface of the area where the mark 2 is located is smooth.

[0142] The first protective layer can be ink. In this embodiment, the ink needs to protect the area where the mark 2 is located, preventing subsequent processing from corroding the first protective layer. For example, in subsequent processing, an acidic reagent such as hydrofluoric acid is needed to roughen the first surface of the substrate. In this case, the ink needs to be acid-resistant to resist the corrosion of the first protective layer formed by the hydrofluoric acid.

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

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

[0145] The colorant is a pigment with certain color coverage and corrosion resistance, which can protect the area where the mark 2 is located and prevent subsequent processing from corroding the protective layer.

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

[0147] Silane coupling agents can improve the bonding performance between colorants and binders, and enhance the dispersion uniformity of various components in inks.

[0148] Organic solvents, as solvents in ink systems, play a dispersing role for other components.

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

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

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

[0152] The composition includes 45% colorant, 15% bisphenol A diglycidyl ether, 10% 3-glycidyl etheroxypropyltrimethoxysilane, 20% ethylene glycol butyl ether, 5% diethylene glycol butyl ether, and 5% tetramethylbenzene.

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

[0154] The composition includes 40% colorant, 10% bisphenol A diglycidyl ether, 15% 3-glycidyl etheroxypropyltrimethoxysilane, 25% ethylene glycol butyl ether, 5% diethylene glycol butyl ether, and 5% tetramethylbenzene.

[0155] Alternatively, the percentage of each component of the ink by mass relative to the total mass of the ink can be expressed as follows:

[0156] The composition includes 50% colorant, 20% bisphenol A diglycidyl ether, 5% 3-glycidyl etheroxypropyltrimethoxysilane, 15% ethylene glycol butyl ether, 5% diethylene glycol butyl ether, and 5% tetramethylbenzene.

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

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

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

[0160] For example, ink is applied to the area where the mark 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. Roughen the first surface 11 of the body on which the first protective layer is provided to obtain a roughened body, so as to form a matte region 11a on the first surface 11.

[0162] In this step, the first surface 11 of the body on which the first protective layer is provided is roughened, and a matte area 11a can be formed on the first surface 11 of the body 1. Since the first protective layer is provided in the area where the mark 2 is located, the surface of the mark area is glossy.

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

[0164] S430: Remove the first protective layer on the roughened body to obtain the first smooth area 11b of the area where the mark 2 is located.

[0165] In this step, the first protective layer is removed to expose the glossy surface of the area where the logo 2 is located, thereby creating a glossy and matte finish 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] For example, 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 area 11b of the area where the identifier 2 is located.

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

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

[0169] S510, Provide a body 1; A mark 2 is provided on the first surface 11 of the body 1.

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

[0171] S520. A second protective layer is provided on the second surface 12 of the body 1 to form a second smooth 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, which can protect the second surface 12 and ensure that the second surface 12 is smooth.

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

[0174] S530. A first protective layer is provided in the area where the mark 2 is located on the first surface 11 of the body 1, thereby obtaining a body with the first protective layer provided.

[0175] S540. The first surface 11 of the body on which the first protective layer is provided is roughened to obtain a roughened body, so as to form a matte region 11a on the first surface 11.

[0176] S550, Remove the first protective layer on the roughened body to obtain the first smooth area 11b where the mark 2 is located.

[0177] Steps S530 to S550 in this embodiment are the same as steps S410 to S430 in the above embodiment, and will not be described again here.

[0178] S560. A coating layer 3 and an ink layer 4 are stacked on the second smooth surface area of ​​the second surface 12 of the body 1, and the projection of the coating layer 3 and the ink layer 4 covers the projection of the area where the mark 2 is located along the thickness direction of the body 1.

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

[0180] In this embodiment, a second protective layer and a first protective layer are respectively provided on the second surface 12 and the first surface 11 of the body 1 to form a second glossy area and a first glossy area 11b. This can avoid surface damage to the second glossy area and the first glossy area 11b caused by subsequent surface roughening treatment. After the coating layer 3 and the ink layer 4 are sequentially stacked in the second glossy area, the mark 2 located in the first glossy area 11b can be brightened through the second glossy area and the first glossy area 11b, thereby improving the aesthetics of the shell appearance.

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

[0182] S610, Provide a body 1; A mark 2 is provided on the first surface 11 of the body 1.

[0183] S620. A second protective layer is provided on the second surface 12 of the body 1 to form a second smooth surface area on the second surface 12.

[0184] S630. A first protective layer is provided in the area where the mark 2 is located on the first surface 11 of the body, thereby obtaining a body with the first protective layer provided.

[0185] S640. Roughen the first surface 11 of the body on which the first protective layer is provided to obtain a roughened body, so as to form a matte region 11a on the first surface 11.

[0186] S650, Remove the first protective layer on the roughened body to obtain the first glossy area 11b of the region where the mark 22 is located, and obtain the body with both glossy and matte finish.

[0187] Steps S610 to S650 in this embodiment are implemented in the same way as steps S510 to S550 in the above embodiment, and will not be described again here.

[0188] S660. Place the glossy and matte body in a strengthening furnace for strengthening treatment.

[0189] In this step, the glossy and matte composite body is placed in a strengthening furnace for strengthening treatment to improve its strength and extend its service life.

[0190] S670. Chemical plating is performed on the second smooth surface area of ​​the body 1 to form a coating layer 3.

[0191] S680. Along the thickness direction of the body 1, mirror silver ink is applied to the projection position of the mark 2 on the coating layer 3 to form ink layer 4, thus obtaining the shell.

[0192] Steps S670 to S680 in this embodiment are implemented in the same way as steps S210 to S220 in the above embodiment, and will not be described again here.

[0193] S690. Apply a decorative film to the surface of the housing and remove air bubbles from the film; fill the concave edge of the housing with ink and remove excess ink to obtain the finished housing.

[0194] In this step, decorative films can be applied to the surface of the casing as needed, and the aesthetics of the finished casing can be further improved after removing air bubbles, repairing the edges of the casing, and removing excess ink.

[0195] The method in this embodiment strengthens the glossy / matte composite body before coating, which increases its strength and extends its service life. Furthermore, the strengthened glossy / matte composite body has explosion-proof properties, improving the safety of the casing.

[0196] In an exemplary embodiment of this disclosure, an electronic device is provided, such as a mobile phone, a laptop computer, a tablet computer, and a wearable device.

[0197] The electronic device includes the aforementioned housing, which enables a combination of glossy and matte finishes, thereby enhancing the device's aesthetics.

[0198] The processing method of the shell provided in this disclosure will be described in detail below with reference to specific preparation examples and embodiments.

[0199] Preparation Example

[0200] Preparation Example 1: 45g of colorant, 15g of bisphenol A diglycidyl ether, 10g of 3-glycidyl etheroxypropyltrimethoxysilane, 20g of ethylene glycol butyl ether, 5g of diethylene glycol butyl ether and 5g of tetramethylbenzene were mixed and stirred evenly to obtain an acid-resistant ink, which was used to coat the marking 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 flake aluminum powder, 10g of resin, 20g of propylene glycol methyl ether and 15g of isophorone, mix and stir evenly to obtain high-gloss mirror silver ink, which is used to coat the coating layer corresponding to the area where the mark is located to form an ink layer.

[0202] Example

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

[0204] Example 1: A method for processing a shell, such as... Figure 1 As shown, it includes:

[0205] (1) Select transparent glass as raw material, and after cutting and polishing the transparent glass, 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 of the body 1 (relative to the outside of the electronic device), and the second surface 12 is the front of the body 1 (relative to the inside of the electronic device). A mark 2 is provided on the first surface 12 of the body 1.

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

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

[0208] (4) The body with the first and second protective layers is subjected to AG treatment on an etched wire to obtain a roughened body, so as to form a matte region 11a on the first surface 11. The haze of the matte region 11a is 60% and the roughness is 2.0×10. 3 nm;

[0209] (5) Use 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 marking 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 glossy and matte body.

[0210] (6) The glossy and matte composite body is placed in a strengthening furnace for strengthening treatment to improve the strength of the glossy and matte composite body.

[0211] (7) The second glossy surface area of ​​the enhanced glossy-matte composite body is chemically coated. The vacuum evaporation coating method is used, and silicon target and titanium target are selected. A silicon dioxide layer / titanium dioxide layer / silicon dioxide layer is sequentially stacked in the second glossy surface area to obtain a coating layer 3 with a thickness of 120nm. The L value of the coating layer is 70 and the ab value is close to 0.

[0212] (8) Along the thickness direction of the body 1, high-gloss mirror silver ink is screen printed on the coating layer 3 at the projection position of the mark 2, and baked at 150°C for 60 minutes to form an ink layer 4 with a thickness of 5μm, thus obtaining the shell.

[0213] (9) Apply a decorative film to the front of the shell and remove air bubbles from the film; apply ink to the concave edge of the shell with the film and remove excess ink to obtain the finished shell.

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

[0215] The color difference ΔE < 2 after 96 hours of UV testing;

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

[0217] Strength 4PB > 400MPa.

[0218] Here, color difference ΔE represents the overall color difference between objects. When ΔE < 2, it indicates that the object has a very slight color deviation, but it is basically indistinguishable to the naked eye. In Example 1, the color difference ΔE < 2 after 96 hours of UV irradiation indicates that the shell has a very slight color deviation before and after 96 hours of UV irradiation, which meets the product quality requirements.

[0219] The cross-cut adhesion test is a method for testing paint film adhesion. According to international standards, it can be divided into 6 levels: 0B, 1B, 2B, 3B, 4B, and 5B. The higher the level (number), the better the paint film adhesion. 4B indicates that small patches of paint peel off at the intersection of the lines, and the total peeling area is less than 5%. Example 1's cross-cut adhesion test level is 4B, indicating that the paint film on the shell of Example 1 has good adhesion.

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

[0221] In summary, the shell prepared by the method of this disclosure not only has a matte finish visual effect, but also enables the marking area to achieve a high-gloss visual effect; furthermore, the obtained shell also has excellent mechanical properties and superior overall performance.

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

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

[0224] In an exemplary embodiment of this disclosure, the first fiber layer 51 and the third fiber layer 53 contain the same type of fiber.

[0225] In an exemplary embodiment of this disclosure, the second fiber layer 52 comprises, by weight 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 better mechanical properties, and the resin can provide better molding properties, which is conducive to the formation of a uniform and dense structure in the second fiber layer 52 and improves the rigidity of the second fiber layer 52.

[0228] For example, the continuous inorganic fiber includes one or more of continuous ceramic fiber, continuous quartz fiber, and continuous silicon fiber. The aforementioned continuous inorganic fiber can provide a higher modulus to the second fiber layer 52, thereby improving the overall modulus and rigidity of the plate-like structure 5.

[0229] For example, the resin includes 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. When 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. The second fiber layer 52 obtained by combining them with continuous inorganic fibers has high strength and modulus, thus playing a skeletal support role for the plate-like structure.

[0231] In an exemplary embodiment of this disclosure, the first fiber layer 51 and / or the third fiber layer 53, by weight percentage, comprise:

[0232] It contains 50-70% aramid fiber and 30-50% resin.

[0233] In this embodiment, aramid fibers have the advantages of high toughness and high impact resistance. Through weaving process, personalized appearance texture can be provided for them. The first fiber layer 51 and / or the third fiber layer 53 made of aramid fibers as the matrix 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 properties.

[0234] Understandably, the aramid fibers in the first fiber layer 51 and / or the third fiber layer 53 can also be replaced by other high-performance fibers with high strength and high modulus, such as 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 serves as an adhesive to facilitate the formation of a dense fiber structure with the aramid fibers. For example, the resin in the first fiber layer 51 and / or the third fiber layer 53 may include one or more of polyester resin, epoxy resin, phenolic resin, and bismaleimide resin.

[0236] Furthermore, 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 course, they can be made of different materials.

[0237] In some embodiments, the first fiber layer 51 may be formed by stacking a predetermined number of fiberboard layers, each fiberboard layer being made of fibers arranged in a specific orientation. It should be understood that the fiberboard has warp and weft threads. For a specific fiberboard, all warp threads may be arranged parallel to each other, and all weft threads may be arranged parallel to each other. The warp and weft threads may be oriented at a predetermined angle to each other. For example, a second predetermined angle between the warp and weft threads in the fiberboard may be set in the range of 30-90 degrees. For instance, the second predetermined angle between the warp and weft threads in the fiberboard may be set to 40 degrees, 60 degrees, 75 degrees, 80 degrees, or 90 degrees. This makes the fiberboard structure more stable, thereby providing higher stress resistance in both the warp and weft directions, further enhancing the strength and structural stability of the plate structure 5 provided by this disclosure.

[0238] In this invention, the fiberboards can be stacked on top of each other. The number of fiberboard layers is limited to 2 to 6. For example, the number of fiberboard layers can be 2, 3, 4, 5, or 6. By changing the stacking angle between the fiberboards, the stacking can be optimized, thereby achieving an ultra-thin shell thickness while ensuring shell strength. The shell can withstand stress from all directions, so that even with a complex integrated shape, the overall stress strength of the shell is high enough and the structure is stable enough.

[0239] For example, the first preset angle between adjacent fiberboards can be selected by considering the number of fiberboard layers, the shape of the board, and the direction and degree of stress. For example, the first preset angle can be in the range of 15 to 75 degrees. In an exemplary example of this disclosure, the housing includes four layers of fiberboard, and the stacking angle between each fiberboard, i.e., the warp and / or weft of adjacent fiberboards, is "0 degrees / 45 degrees / 0 degrees / 45 degrees", with a first preset angle of 45 degrees. Or "0 degrees / 45 degrees / 45 degrees / 0 degrees", with a first preset angle of 45 degrees and 0 degrees. Or the warp and / or weft of adjacent fiberboards is "0 degrees / 60 degrees / 60 degrees / 0 degrees", with a first preset angle of 60 degrees and 0 degrees. Or "0 degrees / 60 degrees / 0 degrees / 60 degrees", with a first preset angle of 60 degrees. Or the warp and / or weft of adjacent fiberboards is "0 degrees / 45 degrees / 60 degrees / 15 degrees", with a first preset angle including 45 degrees, 15 degrees, and 60 degrees. The first preset angle between adjacent fiberboards can be the same or different, and can be flexibly selected according to actual needs. This disclosure does not limit this.

[0240] Similarly, the arrangement of the second fiber layer 52 and the third fiber layer 53 can be referred to the description of the first fiber layer 51, and this disclosure does not limit them.

[0241] In an exemplary embodiment of this disclosure, such as Figure 8 As shown, a plate-like structure 5 is provided, including a first fiber layer 51, a second fiber layer 52, and a third fiber layer 53 stacked together;

[0242] The second fiber layer 52 comprises, by weight percentage: 50-70% continuous ceramic fibers and 30-50% resin;

[0243] By weight percentage, the first fiber layer 51 and / or the third fiber layer 53 comprise: 50-70% aramid fiber and 30-50% resin.

[0244] In this embodiment, the second fiber layer 52 provides skeletal support and has excellent modulus and rigidity; the first fiber layer 51 and the third fiber layer 53 are located on both sides of the second fiber layer 52, respectively, and have excellent toughness and impact resistance, and can also provide a personalized visual effect. When the resulting plate-like structure is used as a housing or back panel of electronic devices, it can combine the advantages of mechanical properties and aesthetic performance, and has good overall performance.

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

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

[0247] For example, 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 serves as a skeleton support material, and its thickness can be the same as or slightly lower than that of the first fiber layer 51 or the second fiber layer 53, thereby obtaining a plate-like structure 5 with better mechanical properties.

[0249] For example, 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 structure 5.

[0253] When the plate-like structure 5 provided in the exemplary embodiments of this disclosure is used to manufacture the housing of an electronic device, the plate-like structure 5 can be used in the body 1 of the housing provided in the exemplary embodiments of this disclosure. Accordingly, the identifier 2 can be provided on the surface of the plate-like structure 5, or the identifier 2 can be provided in any one of the first fiber layer 51, the second fiber layer 52, and the third fiber layer 53 of the plate-like structure 5, and pass through the other fiber layers to protrude from the surface of the plate-like structure 5.
