[0051] In order to make the purpose, technical solution and advantages of the present disclosure clearer, the technical solution of the present disclosure will be clearly and completely described in combination with the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure. It should be noted that the embodiments in the present disclosure and the features in the embodiments can be arbitrarily combined with each other without conflict.

[0052] The preparation of traditional lacquerware generally involves painting a paint layer and applying decorative techniques on the surface of a shell or substrate made of wood, metal or other materials. The finished shell is usually thick, heavy, and has poor overall strength. The strength performance of the surface of the finished shell is also relatively poor. Therefore, the surface paint layer and decorative effects of traditional lacquerware are difficult to achieve on the shell of electronic products.

[0053] Based on this, Figure 1 The longitudinal cross-sectional schematic diagram of the shell shown in the present disclosure provides a shell 10, comprising: a substrate 20, the substrate 20 comprising a first surface, the first surface comprising a fiber material; a natural lacquer layer 30, arranged on the first surface of the substrate 20, the natural lacquer layer 30 forming a first preset pattern; the first preset pattern is formed on a side of the natural lacquer layer 30 away from the substrate 20.

[0054] Fiber materials have excellent properties such as high strength, high modulus, light weight, wear resistance, corrosion resistance, and high temperature resistance; natural paint, also known as lacquer, is a coating made from lacquer tree juice, and has the advantages of bright and clean, durable color, wear resistance, corrosion resistance, and high temperature resistance. A natural paint layer with a first preset pattern is provided on the first surface of a substrate including fiber materials, wherein the first preset pattern is formed on a side of the natural paint layer away from the substrate, so that a shell with small thickness, light weight, high strength, and beautiful appearance can be obtained. The above-mentioned shell provided by the exemplary embodiment of the present disclosure can not only be used on the back cover and bracket of electronic products, but also can be applied to many fields such as automotive interior and home decoration.

[0055] For example, a shell formed by arranging a natural lacquer layer with a "Zhanghua" effect on the first surface of the substrate has the advantages of small thickness, light weight, high strength, and beautiful appearance.

[0056] For example, the substrate can be made of at least one fiber material. The substrate 20 can be a plate-like structure made of one fiber material, or it can be a plate-like structure made of a composite of multiple fiber materials. For example, the substrate 20 in the shell 10 can be a plate-like structure made of ceramic fiber, or it can be a plate-like structure made of a composite of ceramic fiber and glass fiber. Since fiber materials have the advantages of light weight and high strength, the shell 10 using the substrate 20 made of fiber material can have the advantages of being light and thin, so that the user can have a better experience, and it can also have the characteristics of high strength so that the shell 10 is not easily damaged.

[0057] In an exemplary embodiment provided by the present disclosure, the substrate includes a preset number of layers of fiber prepreg; the fiber prepreg includes at least ceramic fiber prepreg.

[0058] Ceramic fiber has the characteristics of low density, high strength, high temperature resistance, oxidation resistance and mechanical vibration resistance. A preset number of layers of ceramic fiber prepreg are hot pressed into a desired shape in a 3D molding mold to obtain a substrate. A natural lacquer layer with a first preset pattern is provided on the first surface of the substrate to form a lightweight, high strength, high temperature resistant, oxidation resistant and mechanical vibration resistant shell.

[0059] Among them, the preset number of layers of fiber prepreg can be set according to actual needs, for example, it can be set according to the thickness or strength requirements of the shell. For example, the preset number of layers of fiber prepreg can be 2-20 layers. For another example, the preset number of layers of fiber prepreg can be 2 layers, 4 layers, 10 layers, and 20 layers, which is not limited in the present disclosure.

[0060] In an exemplary embodiment provided by the present disclosure, the fiber prepreg further includes glass fiber prepreg, and the ceramic fiber prepreg and the glass fiber prepreg are stacked according to a preset rule.

[0061] The fiber material includes a preset number of layers of fiber prepreg; the fiber prepreg includes not only ceramic fiber prepreg, but also glass fiber prepreg. Glass fiber also has the advantages of light weight and high strength, and has no interference with electromagnetic signals. Therefore, glass fiber prepreg can be used together with ceramic fiber prepreg as fiber material to form the base material of the shell.

[0062] Among them, the ceramic fiber prepreg and the glass fiber prepreg are stacked according to preset rules, and the preset rules can be any stacking method set according to actual needs, for example, set according to the thickness or strength requirements of the shell. For example, multiple layers of ceramic fiber prepreg can be stacked first, and then multiple layers of glass fiber prepreg can be stacked, or a single layer of ceramic fiber prepreg and a single layer of glass fiber prepreg can be cross-stacked. In addition, the ceramic fiber prepreg can be set on the topmost or bottommost layer of the substrate, or the glass fiber prepreg can be set on the topmost or bottommost layer of the substrate, and the present disclosure does not limit this.

[0063] In the exemplary embodiments provided in the present disclosure, the thickness of the substrate is 0.1 mm-2 mm; the thickness of the natural paint layer is 0.03 mm-0.5 mm.

[0064] The substrate formed by the fiber material can control the thickness of the substrate within the range of 0.1mm-2mm by controlling the number of layers of ceramic fiber prepreg, or by controlling the number of layers of ceramic fiber prepreg and glass fiber prepreg. Within this substrate thickness range, the substrate can provide strength support for the shell without making the substrate thickness too large, thereby ensuring the strength and reliability of the shell.

[0065] The thickness of the natural lacquer layer is in the range of 0.03mm-0.5mm, so that the first preset pattern can be formed on the side of the natural lacquer layer away from the substrate. For example, the first preset pattern on the side of the natural lacquer layer away from the substrate is a "Zhangcha" effect, and multiple painting is required on the first surface of the substrate to form the natural lacquer layer. The thickness of the natural lacquer layer is 0.03mm-0.5mm.

[0066] In the exemplary embodiments provided in the present disclosure, Figure 2 As shown in the schematic longitudinal section of the shell, the shell 10 further includes a first chemical paint layer 40 disposed between the substrate 20 and the natural paint layer 30 ; the first chemical paint layer 40 is used to bond the substrate 20 and the natural paint layer 30 .

[0067] In order to enhance the bonding force between the substrate and the natural paint layer, a first chemical paint layer is provided between the substrate and the natural paint layer. For example, the first chemical paint layer can be a coating formed by an artificially synthesized chemical coating. The first chemical paint layer is a coating formed by a primer, which is a coating that can enhance the adhesion of the upper coating. The primer layer is provided between the substrate and the natural paint layer to enhance the fullness of the natural paint layer and improve the adhesion of the natural paint layer on the first surface of the substrate, thereby preventing the shell from being knocked during subsequent production and application, causing the natural paint layer to fall off, thereby affecting the appearance of the shell.

[0068] For example, the primer used for the first chemical paint layer can be iron red alkyd resin primer, rubber alkyd primer, zinc yellow polyurethane primer, acrylic / epoxy resin primer, new polyphenol oxygen pre-coating primer, epoxy resin primer of various colors and other types of primers. The selected primer can enhance the bonding strength between the substrate and the natural paint layer. It can be selected according to actual needs and is not limited in the present disclosure.

[0069] In the exemplary embodiments provided in the present disclosure, Figure 3 As shown in the schematic longitudinal section of the shell, the shell 10 further includes a second chemical paint layer 50 disposed on a second surface of the natural paint layer 30 away from the substrate 20 .

[0070] After the first chemical paint layer 40 is arranged on the first surface of the substrate 20, a natural paint layer 30 having a first preset pattern is arranged on the other side of the first chemical paint layer 40 away from the substrate 20, and the formed shell has the effect of the first preset pattern, and the shell has a bright and beautiful appearance and a durable color. A second chemical paint layer 50 is arranged on the second surface of the natural paint layer 30 away from the substrate 20, and the second chemical paint layer 50 has a high gloss or matte effect. On the basis of the first preset pattern on the side of the natural paint layer 30 away from the substrate 20, the shell appearance can further present a high gloss or matte effect, thereby improving the glossiness of the shell appearance, and the coating of the second chemical paint layer 50 can also enhance the hardness of the shell surface. For example, the second chemical paint layer 50 can be a coating formed by artificially synthesized chemical paint.

[0071] In the exemplary embodiments provided by the present disclosure, the second chemical paint layer is at least one of the following: ultraviolet curing paint, polyurethane paint, and rubber paint.

[0072] The second chemical paint layer has a high gloss or matte effect, and the second chemical paint layer can be at least one of ultraviolet curing paint, polyurethane paint, and rubber paint. Among them, ultraviolet curing paint has a higher hardness after curing, polyurethane paint has a better feel after curing, and rubber paint has a lower hardness but a better feel. Therefore, one or more of ultraviolet curing paint, polyurethane paint, and rubber paint can be selected as the second chemical paint layer according to actual needs. After the ultraviolet curing paint, polyurethane paint, and rubber paint with high gloss or matte effect are sprayed on the second surface of the natural paint layer away from the substrate and cured, the formed second chemical paint layer presents a corresponding high gloss or matte effect.

[0073] In an exemplary embodiment provided by the present disclosure, the thickness of the second chemical paint layer is 0.01 mm-0.2 mm.

[0074] A second chemical paint layer is arranged on the second surface of the natural paint layer away from the substrate. The second chemical paint layer has a high gloss or matte effect and a thickness of 0.01mm-0.2mm. On the basis of the first preset pattern on the side of the natural paint layer away from the substrate on the shell appearance, the second chemical paint layer can further present a high gloss or matte effect, thereby improving the glossiness of the shell appearance and enhancing the hardness of the shell surface.

[0075] In the exemplary embodiments provided in the present disclosure, Figure 4 As shown in the schematic longitudinal section of the shell, the shell 10 further includes a third chemical paint layer 60 disposed between the natural paint layer 30 and the second chemical paint layer 50 ; the third chemical paint layer 60 is used to combine the natural paint layer 30 and the second chemical paint layer 50 .

[0076] After the first chemical paint layer 40 is arranged on the first surface of the substrate 20, a natural paint layer 30 having a first preset pattern is arranged on the other side of the first chemical paint layer 40 away from the substrate 20, and then a second chemical paint layer 50 is arranged on the second surface of the natural paint layer 30 away from the substrate 20. This allows the shell 10 to present a high gloss or matte effect on the basis of the first preset pattern of the natural paint layer 30, thereby improving the glossiness of the appearance of the shell 10. At the same time, the coating of the second chemical paint layer 50 can also enhance the hardness of the shell surface. Before the second chemical paint layer 50 is coated on the second surface of the natural paint layer 30 away from the substrate 20, in order to enhance the bonding between the second chemical paint layer 50 and the natural paint layer 30, the third chemical paint layer 60 is first coated on the second surface of the natural paint layer 30 away from the substrate 20. For example, the third chemical paint layer 60 may be a coating formed by an artificially synthesized chemical coating. The third chemical paint layer 60 is a coating formed by a primer, which is a coating capable of enhancing the adhesion of an upper coating. Providing a primer layer between the natural paint layer 30 and the second chemical paint layer 50 can improve the adhesion of the second chemical paint layer 50 on the natural paint layer 30, thereby preventing the second chemical paint layer 50 from falling off due to collisions during subsequent production and application of the shell 10, thereby affecting the appearance of the shell 10.

[0077] For example, the primer used for the third chemical paint layer can be iron red alkyd resin primer, rubber alkyd primer, zinc yellow polyurethane primer, acrylic / epoxy resin primer, new polyphenol oxygen pre-coating primer, epoxy resin primer of various colors and other types of primers. The selected primer can enhance the bonding strength between the natural paint layer and the second chemical paint layer. It can be selected according to actual needs and is not limited in the present disclosure.

[0078] In the exemplary embodiment provided by the present disclosure, the thickness of the first chemical paint layer is 0.005 mm-0.05 mm; the thickness of the third chemical paint layer is 0.005 mm-0.05 mm.

[0079] The first chemical paint layer and the third chemical paint layer are both primer layers, which can enhance the bonding between layers, wherein the first chemical paint layer enhances the bonding between the substrate and the natural paint layer, and the third chemical paint layer enhances the bonding between the natural paint layer and the second chemical paint layer. The thickness of the first chemical paint layer and the third chemical paint layer is in the range of 0.005mm-0.05mm, which can respectively ensure that the natural paint layer is firmly attached to the first surface of the substrate, and the second chemical paint layer is firmly attached to the other surface of the natural paint layer away from the substrate.

[0080] In an exemplary embodiment provided by the present disclosure, the housing may further include a LOGO layer disposed between the third chemical paint layer and the second chemical paint layer.

[0081] In the shell provided by the exemplary embodiment of the present disclosure, a LOGO may be further provided in a preset area of ​​the third chemical paint layer to form a LOGO layer to add a brand mark or special meaning to the shell.

[0082] In the exemplary embodiments provided in the present disclosure, Figure 5 As shown in the schematic longitudinal section diagram of the housing, the housing 10 further includes an optical coating layer 70 disposed on a third surface of the second chemical paint layer 50 away from the third chemical paint layer 60 .

[0083] After the first chemical paint layer 40, the natural paint layer 30, the third chemical paint layer 60, and the second chemical paint layer 50 are sequentially arranged on the first surface of the substrate 20, the appearance of the housing 10 not only presents the first preset pattern of the natural paint layer 30, but also presents a high gloss or matte effect. An optical coating layer 70 is arranged on the third surface of the second chemical paint layer 50 away from the third chemical paint layer 60, so as to achieve a colorless brightening or color effect. It should be noted that the optical coating layer 70 is a transparent film layer to avoid shielding the first preset pattern of the natural paint layer 30 and the presentation of the high gloss or matte effect of the second chemical paint layer 50.

[0084] In the exemplary embodiment provided by the present disclosure, the thickness of the optical coating layer is 0.1 μm-2 μm.

[0085] An optical coating layer is provided on the third surface of the second chemical paint layer away from the third chemical paint layer, so as to achieve a colorless brightening or coloring effect for the appearance of the housing. The optical coating layer is formed on the third surface of the second chemical paint layer away from the third chemical paint layer by an evaporation coating process, and the thickness of the optical coating layer is in the range of 0.1μm-2μm, so as to achieve a colorless brightening or coloring effect for the appearance of the housing.

[0086] In the exemplary embodiments provided in the present disclosure, Figure 6 As shown in the schematic longitudinal section of the housing, the housing 10 further includes a fourth chemical paint layer 80 disposed on a fourth surface of the optical coating layer 70 away from the second chemical paint layer 50 .

[0087] In order to further enrich the appearance of the housing 10, after the first chemical paint layer 40, the natural paint layer 30, the third chemical paint layer 60, the second chemical paint layer 50 and the optical coating layer 70 are sequentially arranged on the first surface of the substrate 20, a fourth chemical paint layer 80 can also be arranged on the fourth surface of the optical coating layer 70 away from the second chemical paint layer 50. For example, the fourth chemical paint layer 80 can be a coating formed by an artificially synthesized chemical coating. The fourth chemical paint layer 80 is formed by embossing a silicone mold after the fourth chemical paint is applied and the fourth chemical paint is cured to a preset degree, such as semi-cured. After the fourth chemical paint layer 80 having a second preset pattern is arranged on the fourth surface of the optical coating layer 70 away from the second chemical paint layer 50, the appearance of the housing 10 can be superimposed to present the first preset pattern of the natural paint layer 30, the highlight or matte effect of the second chemical paint layer 50, the colorless brightening or color effect of the optical coating layer 70, and the appearance effect of the fourth chemical paint layer 70, and the rich visual effect of multi-layer superposition.

[0088] In an exemplary embodiment provided by the present disclosure, a second preset pattern is formed on the fifth surface of the fourth chemical paint layer away from the optical coating layer, and the second preset pattern includes a plane texture and / or a three-dimensional texture.

[0089] The fourth chemical paint layer is formed by coating the fourth chemical paint on the fourth surface of the optical coating layer away from the second chemical paint layer, and after the fourth chemical paint is cured to a preset degree, such as semi-cured, embossing is performed by a silicone mold. Therefore, the fifth surface of the fourth chemical paint layer away from the optical coating layer can not only form a plane texture, but also form a three-dimensional texture appearance effect or feel effect. For example, when the embossed surface of the silicone mold is a plane, after the embossing treatment, the fifth surface of the fourth chemical paint layer away from the optical coating layer can form a plane texture, such as a highlight effect; when the embossed surface of the silicone mold is a three-dimensional texture surface, after the embossing treatment, the fifth surface of the fourth chemical paint layer away from the optical coating layer can form a three-dimensional texture, such as a matte effect, a flash sand effect; when the embossed surface of the silicone mold is a three-dimensional pattern surface, after the embossing treatment, the fifth surface of the fourth chemical paint layer away from the optical coating layer can form a three-dimensional pattern.

[0090] In the exemplary embodiments provided in the present disclosure, the fourth chemical paint layer is at least one of the following: ultraviolet curing paint, polyurethane paint, and rubber paint.

[0091] At least one of UV-curing paint, polyurethane paint, and rubber paint is sprayed onto the fourth surface of the optical coating layer away from the second chemical paint layer. After semi-curing, embossing is performed through a mold, such as a silicone mold, to form a fourth chemical paint layer. Therefore, a second preset pattern is formed on the fifth surface of the fourth chemical paint layer away from the optical coating layer, and the second preset pattern includes a plane texture or a three-dimensional texture.

[0092] In an exemplary embodiment provided by the present disclosure, the thickness of the fourth chemical paint layer is 0.01 mm-0.2 mm.

[0093] A fourth chemical paint layer is disposed on a fourth surface of the optical coating layer away from the second chemical paint layer. The fourth chemical paint layer is formed by embossing a silicone mold to form a second preset pattern. The second preset pattern includes a planar texture and / or a three-dimensional texture appearance effect or a feel effect, such as a high-gloss effect, a matte effect, a flash sand effect, and a three-dimensional pattern effect. If the thickness of the fourth chemical paint layer is too large, the thickness of the shell will increase. If the thickness of the fourth chemical paint layer is too small, a three-dimensional texture cannot be formed. Therefore, in the exemplary embodiment provided in the present disclosure, the thickness of the fourth chemical paint layer is limited to 0.01 mm-0.2 mm.

[0094] It should be noted that the third chemical paint layer, the second chemical paint layer, the optical coating layer, and the fourth chemical paint layer can be set according to whether their respective functions and effects are needed in the actual production and application process. For example, if a high gloss or matte effect is required, a second chemical paint layer can be set; if a colorless brightening or color effect is required, an optical coating layer can be set; if a flat high gloss effect or a three-dimensional texture appearance or feel effect is required, a fourth chemical paint layer can be set; in addition, the first chemical paint layer, the natural paint layer, the third chemical paint layer, the second chemical paint layer, the optical coating layer, and the fourth chemical paint layer can be sequentially set on the first surface of the substrate, so that the appearance of the shell can present the first preset pattern of the natural paint layer, the high gloss or matte effect of the second chemical paint layer, the colorless brightening or color effect of the optical coating layer, and the superimposed appearance effect of the second preset pattern of the fourth chemical paint layer.

[0095] It should be noted that the third chemical paint layer, the second chemical paint layer, the optical coating layer and the fourth chemical paint layer are all transparent, so as to avoid affecting the presentation effect of the first preset pattern of the natural paint layer and the multi-layered appearance effect of the superposition of each layer.

[0096] The exemplary embodiment of the present disclosure provides a method for preparing a housing, such as Figure 7 As shown, the preparation method comprises:

[0097] S100: providing a substrate, the substrate comprising a first surface, the first surface comprising a fiber material;

[0098] S200: forming a natural lacquer layer on a first surface of a substrate, wherein the natural lacquer layer is formed with a first preset pattern; the first preset pattern is formed on a side of the natural lacquer layer away from the substrate.

[0100] Natural lacquer, also known as lacquer, is a coating made from lacquer tree juice, which has the advantages of bright and clean, durable color, wear resistance, corrosion resistance, high temperature resistance, etc. The fiber material is used as the substrate, and a natural lacquer layer with a first preset pattern is formed on the first surface of the substrate including the fiber material, wherein the first preset pattern is formed on the side of the natural lacquer layer away from the substrate, so that a shell with small thickness, light weight, high strength and beautiful appearance can be obtained.

[0101] Among them, the method of forming a natural lacquer layer with a first preset pattern on the first surface of the substrate can be any method based on the first preset pattern. For example, when a natural lacquer layer with a first preset pattern of "Zhangcha" effect is set on the first surface of the substrate, forming a natural lacquer layer on the first surface of the substrate includes: applying natural lacquer as a primer on the first surface of the substrate; polishing the natural lacquer to keep the natural lacquer in a semi-dry state; attaching texture inducers to the natural lacquer surface (the inducers include but are not limited to: leaves, husks, carbon particles, etc.); placing the substrate coated with natural lacquer in a suitable environment to allow the natural lacquer to air-dry; removing the texture inducers to leave the concave texture on the surface of the natural lacquer layer; applying gold primer on the surface of the natural lacquer as an adhesive; sprinkling gold powder on the surface of the gold primer; applying transparent paint on the surface of the gold primer sprinkled with gold powder to make the substrate full in color; sanding the side of the substrate coated with the paint with sandpaper to highlight the pattern left by the inducers; polishing the side of the substrate coated with the paint with an abrasive to form a shiny shell.

[0102] In an exemplary embodiment provided by the present disclosure, the method for preparing the shell further includes: forming a first chemical paint layer between the substrate and the natural paint layer, wherein the first chemical paint layer is used to combine the substrate and the natural paint layer.

[0103] Forming the natural paint layer after coating the first surface of the substrate to form the first chemical paint layer can enhance the bonding force between the substrate and the natural paint layer, wherein the first chemical paint layer is a coating formed by a primer. Forming the first chemical paint layer between the substrate and the natural paint layer can not only enhance the fullness of the natural paint layer, but also improve the adhesion of the natural paint layer to the first surface of the substrate, thereby preventing the shell from being knocked off during subsequent production and application, thereby affecting the appearance of the shell.

[0104] In an exemplary embodiment provided by the present disclosure, the method for preparing the shell further includes: forming a second chemical paint layer on a second surface of the natural paint layer away from the substrate.

[0105] After the first chemical paint layer and the natural paint layer with the first preset pattern are formed on the first surface of the substrate in sequence, the formed shell has the effect of the first preset pattern, and the shell has a bright and beautiful appearance with durable color. In order to improve the appearance of the shell, a second chemical paint can be sprayed on the second surface of the natural paint layer away from the substrate to form a second chemical paint layer, and the second chemical paint layer has a high gloss or matte effect. On the basis of the first preset pattern of the natural paint layer on the shell appearance, a high gloss or matte effect can be further presented, thereby improving the glossiness of the shell appearance. At the same time, the formation of the second chemical paint layer can also enhance the hardness of the shell surface.

[0106] In an exemplary embodiment provided by the present disclosure, the method for preparing the shell further includes: forming a third chemical paint layer between the natural paint layer and the second chemical paint layer; the third chemical paint layer is used to combine the natural paint layer and the second chemical paint layer.

[0107] After the first chemical paint layer, the natural paint layer, and the second chemical paint layer are sequentially formed on the first surface of the substrate, the appearance of the shell can be made to present a first preset pattern of the natural paint layer, and further present a high gloss or matte effect. Before the second chemical paint layer is sprayed and formed on the second surface of the natural paint layer away from the substrate, in order to enhance the combination of the second chemical paint layer and the natural paint layer, the third chemical paint layer is first applied to the second surface of the natural paint layer away from the substrate. The third chemical paint layer is a coating formed by a primer. The primer layer is formed between the natural paint layer and the second chemical paint layer, which can improve the adhesion of the second chemical paint layer on the natural paint layer, and avoid the shell from being knocked during the subsequent production and application process, causing the second chemical paint layer to fall off, affecting the appearance of the shell.

[0108] In an exemplary embodiment provided in the present disclosure, the method for preparing the shell further includes: forming a LOGO layer in a preset area of ​​the third chemical paint layer.

[0109] During the preparation of the shell, in order to add a brand mark or special meaning, before the second chemical paint layer is formed, the ink of the LOGO pattern can be screen-printed on a preset area on the side of the third chemical paint layer away from the natural paint layer, and then baked at a temperature of 70-90°C for 30-50 minutes to form a LOGO layer.

[0110] In an exemplary embodiment provided by the present disclosure, the method for preparing the shell further includes: forming an optical coating layer on a third surface of the second chemical paint layer away from the third chemical paint layer.

[0111] After successively forming a first chemical paint layer, a natural paint layer, a third chemical paint layer, and a second chemical paint layer on the first surface of the substrate, on the basis of the first preset pattern of the natural paint layer presented on the appearance of the housing, a high-gloss or matte effect is also presented. To enhance the appearance effect of the housing, an optical coating layer can be formed on the third surface of the second chemical paint layer away from the third chemical paint layer by means of evaporation coating with a metal oxide as the target. The formation of the optical coating layer can achieve a colorless brightening or color effect.

[0112] In the exemplary embodiments provided by the present disclosure, the method for manufacturing the housing further includes: forming a fourth chemical paint layer on the fourth surface of the optical coating layer away from the second chemical paint layer.

[0113] To further enrich the appearance effect of the housing, after successively disposing a first chemical paint layer, a natural paint layer, a third chemical paint layer, a second chemical paint layer, and an optical coating layer on the first surface of the substrate, a fourth chemical paint layer can also be formed on the fourth surface of the optical coating layer away from the second chemical paint layer. A second preset pattern is formed on the fifth surface of the fourth chemical paint layer away from the optical coating layer. The second preset pattern includes planar texture and / or three-dimensional texture, such as a high-gloss effect, a matte effect, a flash sand effect, and a three-dimensional pattern effect. After forming the fourth chemical paint layer on the fourth surface of the optical coating layer away from the second chemical paint layer, the appearance of the housing can superimpose and present the first preset pattern of the natural paint layer, the high-gloss or matte effect of the second chemical paint layer, the colorless brightening or color effect of the optical coating layer, the high-gloss effect, the matte effect, the flash sand effect, or the three-dimensional pattern effect of the fourth chemical paint layer. Therefore, the housing has a rich appearance effect.

[0114] In the exemplary embodiments provided by the present disclosure, forming a fourth chemical paint layer on the fourth surface of the optical coating layer away from the second chemical paint layer includes: coating the fourth chemical paint on the fourth surface of the optical coating layer away from the second chemical paint layer. After the fourth chemical paint is cured to a preset degree, an initial fourth chemical paint layer is formed. A second preset pattern is formed on the fifth surface of the initial fourth chemical paint layer away from the optical coating layer to form a fourth chemical paint layer with the second preset pattern.

[0115] The fourth chemical paint is sprayed on the fourth surface of the optical coating layer away from the second chemical paint layer, and the fourth chemical paint is cured to a preset degree, for example, after the fourth chemical paint is semi-cured, an initial fourth chemical paint layer is formed, and a fifth surface of the initial fourth chemical paint layer away from the optical coating layer is vacuum embossed by a silicone mold to form a fourth chemical paint layer having a second preset pattern. The second preset pattern is formed by embossing the silicone mold, so the second preset pattern can be not only a plane texture, but also a three-dimensional texture appearance effect or a feel effect. For example, when the embossed surface of the silicone mold is a plane, after embossing, a second preset pattern of a plane texture, such as a second preset pattern of a highlight effect, can be formed; when the embossed surface of the silicone mold is a three-dimensional texture surface, after embossing, a second preset pattern of a three-dimensional texture, such as a second preset pattern of a matte effect or a flash sand effect, can be formed; when the embossed surface of the silicone mold is a three-dimensional pattern surface, after embossing, a second preset pattern of a three-dimensional pattern effect can be formed.
