[0039] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0047] As electronic products become more popular, in addition to the performance of the hardware and software, the appearance of electronic products has also become an important factor for users to consider. The housing has become an important structural component to achieve the appearance effect. Synthetic leather is often used on housings due to its good feel and low cost. The surface of the synthetic leather is decorated by setting simulated leather grain. However, its appearance characteristics are relatively simple. With the popularity of woven textures, some methods directly mount woven base fabrics on the outer surface of the housing to give the housing the appearance and touch of woven textures. However, the woven base fabrics have poor anti-fouling performance, which affects the user experience.

[0048] In light of this, the present disclosure provides an organosilicon leather. The organosilicon leather obtained by the manufacturing method thereof comprises a stacked woven base fabric layer, an organosilicon transparent layer, and an organosilicon tactile layer. Because the organosilicon transparent layer does not obscure the texture of the woven base fabric layer, the resulting organosilicon leather has both the appearance of the woven texture of the woven base fabric layer and the tactile feel of the pre-set texture, as well as the good hand feel provided by the organosilicon tactile layer, providing users with a good visual and tactile experience. Furthermore, the organosilicon leather also exhibits excellent stain resistance and abrasion resistance.

[0049] An exemplary embodiment of the present disclosure provides a silicone leather, Figure 1 As shown, Figure 1 3 is a schematic diagram of a silicone leather according to an exemplary embodiment. The silicone leather 100 includes a woven base fabric layer 10 , a silicone transparent layer 20 and a silicone tactile layer 30 .

[0050] The woven base fabric layer 10 serves as a carrier for the silicone transparent layer 20 and the silicone tactile layer 30. When the silicone leather 100 is attached to a structural component, the woven base fabric layer 10 serves as the contact and bonding surface between the silicone leather 100 and the structural component. The woven base fabric layer 10 can be woven from fibers, resulting in a unique woven texture. The fibers woven to form the woven base fabric layer 10 can include, but are not limited to, one or more of polyester fibers, nylon fibers, carbon fibers, glass fibers, aramid fibers, basalt fibers, and silicon carbide fibers.

[0051] The present disclosure does not limit the type of weave texture presented by the woven base fabric layer 10. It can be plain, twill, or satin. It can also be woven by arranging fibers of different colors to produce a woven texture with a striped texture, a V-shaped texture, a diamond texture, or other shaped textures, or a combination of multiple textures to form a predetermined pattern. It is understood that when using multiple fibers for weaving, the multiple fibers can be bundled into a mixed fiber and woven using this mixed fiber; different types of fibers can also be woven as warp and weft yarns, etc. For example, the thickness of the woven base fabric layer 10 can be controlled by adjusting the weave texture, the weaving density of the warp and weft yarns, etc.

[0052] In some examples, the thickness of the woven base fabric layer 10 can be 0.15mm-0.35mm. If the thickness of the woven base fabric layer 10 is too low, the mechanical properties and reliability of the formed silicone leather 100 may be poor. If the thickness of the woven base fabric layer 10 is too high, the softness of the woven base fabric layer 10 decreases, which may cause the flexibility of the formed silicone leather 100 to be poor.

[0053] In some examples, by controlling the thickness ratio C1 = woven base fabric layer 10 / silicone leather 100 to be within the range of 0.39-0.48, the woven base fabric layer 10 can provide the silicone leather 100 with good mechanical strength, flexibility and reliability, so that the silicone leather 100 can provide good protection for some valuable structural parts.

[0054] The transparent silicone layer 20 is transparent and light-transmissive, and does not obstruct the woven texture of the woven base fabric layer 10. Furthermore, because the molecular chain of the silicone material consists of a main siloxane segment and side chains of alkyl groups such as methyl, the methyl and other alkyl segments have weak polarity and low surface energy, making the transparent silicone layer 20 highly hydrophobic and oleophobic. This protects the woven base fabric layer 10 while also imparting excellent stain resistance to the resulting silicone leather 100.

[0055] The preset texture 21 is set on the surface of the organic silicone transparent layer 20 away from the woven base fabric layer 10. The preset texture 21 can be any texture pre-designed by the designer, for example, it can be a stripe, diamond, grid, woven pattern or other texture. The preset texture 21 can make the surface of the organic silicone transparent layer 20 away from the woven base fabric layer 10 have an uneven touch, so as to provide the user with a special texture feel.

[0056] The silicone feel layer 30 covers the surface of the transparent silicone layer 20 facing away from the woven base fabric layer 10. In other words, the silicone feel layer 30 serves as the outermost surface of the silicone leather 100 and can adjust the feel of the silicone leather 100, for example, creating a smooth or matte feel. The silicone feel layer 30 is also made of silicone material, making the outermost surface of the silicone leather 100 stain-resistant.

[0057] It should be noted that the silicone feel layer 30 is also transparent to prevent it from obscuring the woven texture of the woven base fabric layer 10. Since the surface of the transparent silicone layer 20 is formed with the predetermined texture 21, the surface of the silicone feel layer 30 formed on the transparent silicone layer 20 also has the shape of the predetermined texture 21, thereby preventing the silicone feel layer 30 from adversely affecting the tactile feel of the predetermined texture 21.

[0058] In some examples, the silicone tactile layer 30 can be configured to have a relatively small thickness. If the silicone tactile layer 30 is too thick, it will not significantly enhance the tactile experience of the silicone leather 100. Instead, it may easily obscure the predetermined texture 21 on the surface of the transparent silicone layer 20, diminishing the textured feel of the silicone leather 100. If the silicone tactile layer 30 is too thin, it may not provide a satisfactory tactile feel. For example, the silicone tactile layer 30 may be 0.01 mm to 0.05 mm thick.

[0059] The silicone leather provided by the present invention has both the appearance and texture of a woven texture. Compared with the synthetic leather with a single appearance of simulated leather grain in the prior art, it can provide users with a good texture tactile experience and a woven texture visual effect. At the same time, it also has good anti-fouling performance, thereby improving the user experience.

[0060] In some examples, the organosilicon transparent layer includes, in parts by mass: vinyl silicone oil: 100-200 parts by mass; vinyl MQ resin: 10-20 parts by mass; reinforcing filler: 30-50 parts by mass; hydroxy silicone oil: 3-10 parts by mass; hydrogen-containing silicone oil: 10-30 parts by mass; platinum catalyst: 0.1-0.5 parts by mass; inhibitor: 0.02-0.1 parts by mass.

[0061] Vinyl MQ resin is an organic silicone resin composed of a tetrafunctional siloxane condensation chain segment (Q) and a monofunctional siloxane chain segment (M). The reactivity of the vinyl group in the vinyl MQ resin is lower than that of the vinyl group in the vinyl silicone oil. In the initial stage of catalytic addition to form the organic silicone transparent layer, the vinyl MQ resin will not compete with the vinyl silicone oil for reaction sites. As the vinyl silicone oil is consumed, the vinyl MQ resin will undergo a cross-linking reaction with the hydrogenated silicone oil, thereby achieving a good reinforcement effect.

[0062] Reinforcing fillers can provide wear resistance to the transparent silicone layer. Transparent fillers can be used to avoid adversely affecting the transparency of the transparent silicone layer. Platinum catalysts are primarily used to catalyze the hydrosilylation reaction between components. Platinum catalysts can include at least one of elemental platinum and platinum-containing compounds. Specifically, they can include, but are not limited to, inorganic substances such as chloroplatinic acid and various platinum-coordinated organic compounds. In combination with the platinum catalyst, the inhibitor's function is primarily to control the rate of the hydrosilylation reaction. Inhibitors can include at least one of 3-methyl-1-butyn-3-ol, 1-ethynyl-1-cyclohexanol, phenylbutynol, tetramethyldivinyldisiloxane, 1,3,5,7-tetramethylcyclotetrasiloxane, and polyvinyl silicone oil.

[0063] In some examples, the thickness of the organosilicon transparent layer 20 can be 0.17 mm to 0.22 mm. Since the organosilicon transparent layer 20 serves as an intermediate transition layer for the organosilicon leather 100, maintaining an appropriate thickness of the organosilicon transparent layer 20 can ensure that the organosilicon transparent layer 20 has good flexibility and mechanical properties such as tear strength and abrasion resistance. If the thickness is too high, the organosilicon transparent layer 20 may lose its flexibility; if the thickness is too low, the organosilicon transparent layer 20 may lose its mechanical properties.

[0064] In some examples, since the organosilicon transparent layer 20 and the organosilicon tactile layer 30 together form the organosilicon layer covering the woven base fabric layer 10, and the organosilicon transparent layer 20 serves as the main structure of the organosilicon layer, by controlling the thickness ratio of the organosilicon transparent layer 20 to a larger value, the organosilicon layer covering the woven base fabric layer 10 has good flexibility and mechanical properties, ensuring the reliability of the organosilicon leather 100. For example, the thickness ratio C2 = organosilicon transparent layer / (organosilicon transparent layer + organosilicon tactile layer) can range from 0.77 to 0.95. In some examples, the thickness ratio C2 = organosilicon transparent layer / (organosilicon transparent layer + organosilicon tactile layer) ranges from 0.85 to 0.95.

[0065] In some examples, the silicone hand-feel layer includes, in parts by mass: vinyl fluorosilicone rubber: 20-50 parts by mass; vinyl silicone oil: 50-80 parts by mass; vinyl MQ resin: 20-40 parts by mass; lubricant: 1-5 parts by mass; hydrogenated silicone oil: 10-30 parts by mass; platinum catalyst: 0.1-0.5 parts by mass; inhibitor: 0.02-0.1 parts by mass.

[0066] Vinyl fluorosilicone rubber is incorporated into the silicone feel layer. Due to the introduction of fluorinated groups, the resulting silicone feel layer retains the stain resistance of silicone materials while also possessing the excellent oil resistance, acid and alkali resistance, weathering resistance, and lower surface energy of fluorinated materials, resulting in excellent reliability for silicone leather. Furthermore, a lubricant, such as a branched silicone resin, is incorporated into the silicone feel layer, imparting a smooth feel and a good surface gloss to the silicone leather.

[0067] In some examples, reference Figure 2 As shown, the organic silicone leather 100 further includes an adhesive layer 40 , which is sandwiched between the woven base fabric layer 10 and the organic silicone transparent layer 20 .

[0068] Because the transparent silicone layer 20 has inert properties such as hydrophobicity and oleophobicity, its adhesion to the woven base fabric layer 10 is poor, posing a risk of the transparent silicone layer 20 falling off. Adding a tackifier to the material forming the transparent silicone layer 20 to improve adhesion between the transparent silicone layer 20 and the woven base fabric layer 10 can easily alter the properties of the transparent silicone layer 20, such as reducing its softness, elasticity, light transmittance, and stability. Therefore, an adhesive layer 40 is provided between the woven base fabric layer 10 and the transparent silicone layer 20 to enhance adhesion between the transparent silicone layer 20 and the woven base fabric layer 10.

[0069] The adhesive layer 40 can chemically react with the woven base fabric layer 10 and the transparent silicone layer 20, chemically bonding the woven base fabric layer 10 to the transparent silicone layer 20, thereby strengthening the molecular bonding between the interfaces, thereby enhancing the interfacial bonding between the transparent silicone layer 20 and the woven base fabric layer 10, and enhancing the connection strength between the transparent silicone layer 20 and the woven base fabric layer 10. In addition, the adhesive layer 40 can also form a physical mosaic structure with the woven base fabric layer 10. That is, during the process of forming the adhesive layer 40, the material forming the adhesive layer 40 can be embedded in the texture of the woven base fabric layer 10, or penetrate into the fibers of the woven base fabric layer 10, so that the adhesive layer 40 can directly have a high interfacial bonding strength with the woven base fabric layer 10.

[0070] For example, the material forming the adhesive layer 40 may include, but is not limited to, silicone glue, silane coupling agent, titanate coupling agent, etc. In some examples, the material forming the adhesive layer 40 may be a silane coupling agent, which can provide siloxy and epoxy groups. The siloxy groups can chemically bond with the woven base fabric layer 10, and the epoxy groups, after ring opening, can react with the silanol groups in the organosilicon transparent layer 20 to form a bond, thereby achieving chemical bonding between the woven base fabric layer 10 and the organosilicon transparent layer 20.

[0071] For example, if the thickness of the adhesive layer 40 is too low, the interfacial bonding force provided by the adhesive layer 40 will not allow for a good bond between the transparent silicone layer 20 and the woven base fabric layer 10, and the transparent silicone layer 20 will easily fall off. If the thickness of the adhesive layer 40 is too high, the overall thickness of the silicone leather 100 will be too high, while the bonding strength between the transparent silicone layer 20 and the woven base fabric layer 10 will not be significantly improved. Therefore, the thickness of the adhesive layer 40 can be controlled between 0.05 mm and 0.1 mm.

[0072] In some examples, the silicone leather 100 is tested for its wear resistance, stain resistance, scratch resistance, and interlayer peeling force. The wear resistance test involves rubbing the outer surface of the silicone leather 100 (i.e., the surface of the silicone hand-feel layer 30) with denim cloth in a circular motion. The silicone leather 100 can show no visible signs of wear after being subjected to the denim circular motion test for more than 2,500 times. Furthermore, the interlayer peeling force of the silicone leather 100 is ≥ 20N.

[0073] In an exemplary embodiment of the present disclosure, a method for making silicone leather is provided, referring to Figure 3 As shown, Figure 3 FIG1 is a flow chart of a method for manufacturing silicone leather according to an exemplary embodiment. The method for manufacturing silicone leather includes the following steps:

[0074] Step S100: providing a woven base fabric layer;

[0075] Step S200: forming a transparent silicone layer on the surface of the woven base fabric layer, wherein a surface of the transparent silicone layer facing away from the woven base fabric layer is formed with a preset texture;

[0076] Step S300: forming an organic silicone hand-feel layer on the surface of the organic silicone transparent layer facing away from the woven base fabric layer to obtain organic silicone leather.

[0077] In step S100, refer to Figure 1 As shown, the woven base fabric layer 10 serves as a carrier for the silicone transparent layer 20 and the silicone tactile layer 30. When the silicone leather 100 is mounted on a structural component, the woven base fabric layer 10 serves as the surface for contact and bonding between the silicone leather 100 and the structural component. The woven base fabric layer 10 can be woven from one or more fibers including, but not limited to, polyester fiber, nylon fiber, carbon fiber, glass fiber, aramid fiber, basalt fiber, and silicon carbide fiber, resulting in a woven texture.

[0078] In some examples, the woven base fabric layer 10 can be woven from fibers having a lustrous or colored texture. For example, when the woven base fabric layer 10 is woven from colored glass fiber material, colored glass yarn is obtained by refining glass raw materials, coloring the glass liquid, bundling the glass fibers, and then collecting the yarn. Using the colored glass yarn as the raw material, warping, reeding, and weaving are performed on a reeding machine used for weaving base fabric to obtain a base fabric. The base fabric is then cut to a suitable size to obtain the woven base fabric layer 10. The fineness of the glass fiber yarn can be selected between 600D and 900D, that is, thicker glass fiber yarn is selected for weaving, so that the woven texture of the woven base fabric layer 10 is more obvious. For example, the thickness of the woven base fabric layer 10 can be controlled by adjusting the weaving texture, the weaving density of the warp and weft yarns, etc. In some examples, the thickness of the woven base fabric layer 10 can be 0.15mm-0.35mm.

[0079] In step S200, refer to Figure 1 As shown, a transparent silicone material can be coated on the surface of the woven base fabric layer 10, and after the silicone material is cured, a silicone transparent layer 20 is formed on the surface of the woven base fabric layer 10. Alternatively, the silicone material can be coated on a release paper, and after the silicone material is cured, it is transferred to the surface of the woven base fabric layer 10 for bonding to obtain the silicone transparent layer 20. The silicone transparent layer 20 is transparent and light-transmitting, and will not block the woven texture of the woven base fabric layer 10. At the same time, since the silicone transparent layer 20 has good hydrophobicity and oleophobicity, it can protect the woven base fabric layer 10 while making the formed silicone leather 100 have good anti-fouling properties. Exemplarily, the thickness of the silicone transparent layer 20 can be between 0.17mm and 0.22mm.

[0080] A preset texture 21 is formed on the surface of the transparent silicone layer 20 facing away from the woven base fabric layer 10. The preset texture 21 can be any texture pre-designed by the designer, such as stripes, diamonds, lattices, or woven patterns. The preset texture 21 can provide a textured feel to the user. The preset texture 21 can be formed simultaneously with the formation of the transparent silicone layer 20. For example, before the silicone material forming the transparent silicone layer 20 is cured, a mold or release paper with a preset texture shape is placed on the surface of the silicone material. The silicone material is cured while covered with the mold or release paper, thereby forming the preset texture 21 on the surface of the transparent silicone layer 20. Alternatively, after the transparent silicone layer 20 is formed, the preset texture 21 can be formed on the surface of the transparent silicone layer 20 by laser engraving or etching.

[0081] In step S300, refer to Figure 1 After forming the transparent silicone layer 20, a silicone feel layer 30 is formed on the surface of the transparent silicone layer 20 facing away from the woven base fabric layer 10. The silicone feel layer 30 serves as the outermost surface of the silicone leather 100 and provides the silicone leather 100 with a good tactile feel. The silicone feel layer 30 can be formed of a silicone material. To form the silicone feel layer 30, the silicone material can be applied to the surface of the transparent silicone layer 20 and cured to form the silicone feel layer 30.

[0082] It should be noted that to prevent the silicone feel layer 30 from obscuring the woven texture of the woven base fabric layer 10, the silicone feel layer 30 is also transparent. Since the surface of the transparent silicone layer 20 is formed with the predetermined texture 21, the surface of the silicone feel layer 30 formed on the transparent silicone layer 20 also has the shape of the predetermined texture 21. Furthermore, to prevent the silicone feel layer 30 from affecting the tactile feel of the predetermined texture 21, the silicone feel layer 30 can be relatively thin. For example, the thickness of the silicone feel layer 30 can be 0.01 mm to 0.05 mm.

[0083] The organic silicone leather obtained by the production method of organic silicone leather provided in the present disclosure has both the appearance effect and texture touch of a woven texture, which can bring users a good texture tactile experience and a woven texture visual effect. At the same time, it also has good anti-fouling performance, thereby improving the user experience.

[0084] In an exemplary embodiment, in step S200 of the method for manufacturing silicone leather provided in the above embodiment, forming a transparent silicone layer on the surface of the woven base fabric layer includes:

[0085] Step S210: Coating a first organosilicon material on the surface of the woven base fabric layer, and before the first organosilicon material is cured, covering the surface of the first organosilicon material facing away from the woven base fabric layer with a textured release paper;

[0086] Step S220: curing the first organosilicon material under a first preset condition to form an organosilicon transparent layer;

[0087] Step S230: removing the textured release paper, and forming a preset texture on the surface of the transparent silicone layer facing away from the woven base fabric layer.

[0088] In this embodiment, reference Figure 4 As shown, a first organosilicon material is coated on the surface of the woven base fabric layer 10. The first organosilicon material is used to form the organosilicon transparent layer 20. The first organosilicon material may include components such as a silicone base, a crosslinking agent, a catalyst, and a reinforcing agent. In some examples, the first organosilicon material may include, by weight, 100-200 parts vinyl silicone oil; 10-20 parts vinyl MQ resin; 30-50 parts reinforcing filler; 3-10 parts hydroxyl silicone oil; 10-30 parts hydrogenated silicone oil; 0.1-0.5 parts platinum catalyst; and 0.02-0.1 parts inhibitor.

[0089] After the first silicone material is applied and before the first silicone material is cured, a textured release paper 22 is applied to the surface of the first silicone material facing away from the woven base fabric layer 10. In this case, the first silicone material is cured, causing a cross-linking reaction and solidification to form a transparent silicone layer 20. The surface of the transparent silicone layer 20 facing away from the woven base fabric layer 10 forms the texture provided on the textured release paper 22, i.e., the predetermined texture 21. In other words, the texture provided on the textured release paper 22 corresponds to the predetermined texture 21 and can, for example, be a plain weave, anti-glare pattern, lattice pattern, Kevlar pattern, or the like.

[0090] The first preset condition for curing the first organosilicon material can be selected and adjusted based on the components of the first organosilicon material. For example, a tunnel oven can be used to thermally cure the first organosilicon material, and the curing temperature and curing time used during thermal curing are the first preset conditions. In some examples, the curing temperature can be between 95°C and 105°C, and the curing time can be between 4 minutes and 7 minutes. Of course, other equipment can also be used to cure the first organosilicon material, and the first preset condition can be adjusted according to actual needs.

[0091] After the first organosilicon material is cured to form the organosilicon transparent layer 20, the textured release paper 22 is removed. For example, a winder can be used to separate the textured release paper 22 from the surface of the organosilicon transparent layer 20. This creates a predetermined texture 21 corresponding to the textured release paper 22 on the surface of the organosilicon transparent layer 20 facing away from the woven base fabric layer 10, thereby imparting a pleasant texture to the organosilicon leather 100.

[0092] In some examples, in step S300 of the method for manufacturing silicone leather provided in the above embodiment, forming the silicone hand-feel layer on the surface of the silicone transparent layer facing away from the woven base fabric layer includes:

[0093] A second organic silicon material is coated on the surface of the organic silicon transparent layer away from the woven base fabric layer, and the second organic silicon material is cured under a second preset condition to form an organic silicon hand-feel layer.

[0094] In this embodiment, reference Figure 1 As shown, a second organosilicon material is applied to the surface of the transparent organosilicon layer 20 facing away from the woven base fabric layer 10. This second organosilicon material is used to form the organosilicon feel layer 30 and may include components such as a silicone base, a crosslinking agent, a catalyst, and a feel modifier. In some examples, the second organosilicon material may include, by weight, 20-50 parts vinyl fluorosilicone rubber; 50-80 parts vinyl silicone oil; 20-40 parts vinyl MQ resin; 1-5 parts lubricant; 10-30 parts hydrogenated silicone oil; 0.1-0.5 parts platinum catalyst; and 0.02-0.1 parts inhibitor.

[0095] After coating the second organosilicon material, the second organosilicon material is cured so that the second organosilicon material undergoes a cross-linking reaction and solidifies to form an organosilicon feel layer 30. The second preset condition for the curing of the second organosilicon material can be selected and adjusted based on the components of the second organosilicon material. For example, a tunnel furnace can be used to thermally cure the second organosilicon material, and the curing temperature and curing time used during thermal curing are the second preset conditions. In some examples, the curing temperature can be between 100°C and 140°C, and the curing time can be between 5 minutes and 10 minutes. Of course, other equipment can also be used to cure the first organosilicon material, and the first preset condition can be adjusted according to actual needs.

[0096] In some possible implementations, before step S200 of the method for manufacturing the silicone leather provided in the above embodiment, that is, before forming the transparent silicone layer on the surface of the woven base fabric layer, the manufacturing method further includes:

[0097] Step S101: forming an adhesive layer on the surface of the woven base fabric layer.

[0098] In this embodiment, reference Figure 2As shown, due to the inert properties of the organic silicone transparent layer 20, such as hydrophobicity and oleophobicity, the adhesion between the organic silicone transparent layer 20 and the woven base fabric layer 10 is poor, posing a risk of the organic silicone transparent layer 20 falling off. Adding a tackifier to the material forming the organic silicone transparent layer 20 can easily alter the properties of the organic silicone transparent layer 20, such as reducing its softness, elasticity, light transmittance, and stability. Therefore, before forming the organic silicone transparent layer 20 on the surface of the woven base fabric layer 10, an adhesive layer 40 is first formed on the surface of the woven base fabric layer 10. The adhesive layer 40 can chemically react with the woven base fabric layer 10 and the organic silicone transparent layer 20, chemically bonding the woven base fabric layer 10 to the organic silicone transparent layer 20, thereby strengthening the molecular bonding between the organic silicone transparent layer 20 and the woven base fabric layer 10 and enhancing the bonding strength between the organic silicone transparent layer 20 and the woven base fabric layer 10. For example, the thickness of the adhesive layer 40 can be controlled between 0.05 mm and 0.1 mm.

[0099] In some examples, in step S101 of the above embodiment, forming an adhesive layer on the surface of the woven base fabric layer includes:

[0100] Step S201: coating a silane coupling agent on the surface of the woven base fabric layer;

[0101] Step S202: drying the silane coupling agent under a third preset condition to form an adhesive layer.

[0102] In this embodiment, reference Figure 2 The material forming the adhesive layer 40 includes a silane coupling agent, which provides siloxy groups that can chemically bond with the woven base fabric layer 10. Simultaneously, the hydrogenated silicone oil in the material forming the organic silicone transparent layer 20 can be hydrolyzed under appropriate conditions to form silanol groups. These silanol groups can react with the epoxy groups provided by the silane coupling agent, thereby chemically bonding the woven base fabric layer 10 to the organic silicone transparent layer 20.

[0103] When forming the adhesive layer 40, a silane coupling agent is applied to the surface of the woven base fabric layer 10 and dried under a third preset condition to prevent the silane coupling agent from mixing with the silicone material forming the silicone transparent layer 20 when the silicone material is subsequently applied to form the silicone transparent layer 20. This ensures that the adhesive layer 40 formed by the silane coupling agent is in close contact with the surface of the woven base fabric layer 10, thereby ensuring a good bonding effect of the adhesive layer 40 between the woven base fabric layer 10 and the silicone transparent layer 20.

[0104] The third preset condition can be a condition that allows the silane coupling agent to transition from a liquid state to a solid state while preventing deformation of the woven base fabric layer 10. For example, a tunnel oven can be used to dry the silane coupling agent, and the drying temperature and drying time used during drying are the third preset condition. In some examples, the drying temperature can be between 100°C and 140°C, and the drying time can be between 4 minutes and 7 minutes. Of course, other equipment can also be used to dry the silane coupling agent, and the second preset condition can be adjusted according to actual needs.

[0105] In an exemplary embodiment, the present disclosure further provides a housing, which can be used as a shell for electronic devices such as mobile phones and tablets that have appearance requirements. Figure 5 As shown, the housing 200 includes a housing substrate 201 and the silicone leather 100 provided in the above-mentioned embodiments of the present disclosure. The housing substrate 201 is laminated to the woven base fabric layer 10 of the silicone leather 100. In other words, the silicone tactile layer 30 of the silicone leather 100 serves as the exterior surface of the housing 200. Because the silicone leather 100 combines the textured feel of a woven texture with the pleasant hand feel provided by the silicone tactile layer, while also offering excellent stain resistance and abrasion resistance, the housing 200 equipped with the silicone leather 100 also exhibits the effects of the silicone leather 100.

[0106] The housing substrate 201 serves as the main body of the housing 200 and can be formed from materials such as glass, ceramic, glass-ceramic, composite sheet material, or fiber-reinforced composite material. Fiber-reinforced composite materials include a resin matrix and reinforcing fibers impregnated with the resin matrix. The reinforcing fibers can be fiber mats or fiber cloths, and can be formed from one or more of polyester fibers, nylon fibers, carbon fibers, glass fibers, aramid fibers, basalt fibers, and silicon carbide fibers. The resin matrix can include, but is not limited to, epoxy resins, polyurethane resins, polyester resins, and the like.

[0107] The following provides a specific processing example for a shell substrate 201 formed from a fiber-reinforced composite material. Because fiber mats and fiber cloths are relatively thin, typically only between 0.1 mm and 0.15 mm, the thickness of a fiber-reinforced composite material formed from a single layer of fiber mat or fiber cloth is relatively small, resulting in low reliability for the resulting shell substrate 201. Therefore, based on product thickness requirements, multiple layers of fiber-reinforced composite materials can be stacked and cut to the dimensions of the shell 200. The stacked layers are then placed in a forming mold and hot-pressed using a hot press. The matrix resins in adjacent layers of fiber-reinforced composite materials are thermally melted and bonded together, forming the fiber-reinforced composite material into the shell substrate 201. The hot-pressing temperature and time used during hot-pressing can be determined based on the type of matrix resin in the fiber-reinforced composite material. In some examples, the hot-pressing temperature can be 120°C to 130°C, and the hot-pressing time can be 8 to 13 minutes. In some examples, the thickness of the formed shell substrate 201 is 0.4 mm to 0.45 mm.

[0108] For example, the silicone leather 100 can be bonded to the housing substrate 201 via an adhesive layer to improve the connection reliability between the silicone leather 100 and the housing substrate 201. Specifically, the adhesive layer can be made of an adhesive medium with a certain viscosity, such as hot melt adhesive.

[0109] The following provides a specific example of laminating the silicone leather 100 to the housing substrate 201: Lamination can include pre-lamination, hot pressing, and cold pressing. Specifically, a layer of hot melt adhesive film can be applied to the surface of the woven base fabric layer 10 of the silicone leather 100 at 60°C-70°C as an adhesive layer. The hot melt adhesive film is pre-activated using a hot press, and the housing substrate 201 and the silicone leather 100 are aligned and pre-laminated. The pre-laminated housing substrate 201 and silicone leather 100 are placed in a hot press. The hot melt adhesive film on the back of the silicone leather 100 is fully activated at 120°C-150°C, laminating the silicone leather 100 to the housing substrate 201 and ensuring adhesion. The hot-pressed silicone leather 100 and housing substrate 201 are then placed in a cold press, held at a certain pressure for a certain period of time, and the hot melt adhesive film is cooled and shaped to ensure the surface smoothness of the resulting housing 200. Subsequently, the edges of the shaped shell 200 are punched to remove the skirt formed by the excess material after the shaping and lamination. Then, at least two layers of sealing oil are applied to the edge side walls of the shell 200. The thickness of the sealing oil can be 15μm-25μm, and the sealing oil can be made of water-based ink. After baking at 40℃-50℃ for 20min-40min, the surface of the sealing oil can be dried for the next application of sealing oil. After the sealing oil is fully applied, it can be completely dried and solidified after baking at 70℃-80℃ for 60min-80min. The sealing oil can prevent the edge of the shell 200 from degumming and modify the burrs on the edge. By laminating the shell substrate 201 with the silicone leather 100 through the above method, the obtained shell 200 can have a good texture and feel.

[0110] The embodiment of the present application further provides an electronic device, which may include but is not limited to at least one of a mobile phone, a tablet computer, and a wearable device, and may specifically include the above-mentioned housing. The embodiment of the present application does not limit the specific type of the electronic device.
