[0011] In some embodiments, the method for preparing a home appliance panel is used to prepare a home appliance panel as described above. The preparation method includes: coating an ink adhering liquid onto the front side of a cleaned glass substrate and allowing it to stand for a set time to form an adhering liquid layer; spraying a preset colored pattern onto the adhering liquid layer to form a colored pattern layer; preparing a PET film with a glass texture layer and a functional coating sequentially disposed on one side; and pressing and curing the functional coating of the PET film toward the colored pattern layer to obtain the home appliance panel.

[0012] Optionally, a glass ink adhering liquid may be coated on the front side of the cleaned glass substrate, including spraying the ink adhering liquid or wiping it onto the front side of the glass substrate with a non-woven cloth.

[0013] Optionally, a preset color pattern is sprayed onto the adhesive liquid layer to form a color pattern layer, including: editing a first design file corresponding to the preset color pattern on a UV printer; causing the UV printer to run according to the first design file to spray color UV ink onto the adhesive liquid layer to form a color pattern layer; wherein the color K value in the first design file is less than or equal to 90.

[0014] Optionally, the preparation of a PET film having a glass texture and a functional coating sequentially disposed on one side includes: laying a PET base film flat on a UV printer and fixing it using the adsorption function of the UV printer; spraying a preset texture onto one side surface of the PET base film to form a glass texture layer; and spraying an AF coating liquid onto the glass texture layer to form a functional coating, thereby obtaining a PET film with a glass texture and a functional coating.

[0015] Optionally, a preset texture is sprayed onto one side of the PET base film to form a glass-like texture layer, including: editing a second design file corresponding to the preset texture on a UV printer; running the UV printer according to the second design file to spray a set number of layers of transparent UV ink onto the surface of the PET base film to form a glass-like texture layer; wherein, in the second design file, the black K value is greater than or equal to 90, and the gray K value is greater than or equal to 50.

[0016] Optionally, when the tactile intensity corresponding to the preset texture is less than or equal to the set tactile intensity, the number of layers is set to 3 to 5; when the tactile intensity corresponding to the preset texture is less than or equal to the set tactile intensity, the number of layers is set to 8 to 10.

[0038] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0039] Combination Figure 1 andFigure 2 As shown, this embodiment of the present disclosure provides a home appliance panel 100, including: a glass substrate 110, an adhesive liquid layer 120, a colored pattern layer 130, and a PET film 140. The adhesive liquid layer 120 is disposed on the front side of the glass substrate 110. The colored pattern layer 130 is disposed on the adhesive liquid layer 120 and is prepared by spraying a preset colored pattern onto the adhesive liquid layer 120. The PET film 140 includes a PET base film 141 and a glass texture layer 142 and a functional coating 143 sequentially disposed on one side of the PET base film 141. The functional coating 143 of the PET film 140 faces the colored pattern layer 130 and is imprinted and cured onto the colored pattern layer 130.

[0040] Specifically, the glass substrate 110 has excellent transparency. Using the glass substrate 110 as the basic structural layer of the entire appliance panel 100 allows the appliance panel 100 to have an overall sense of transparency. The glass substrate 110 has good mechanical strength and stability, and can withstand certain external impacts and wear during daily use. Using the glass substrate 110 as the basic structural layer of the entire appliance panel 100 can provide basic physical support and protection for the appliance panel 100, and provide a load-bearing platform for other layers.

[0041] Specifically, the glass substrate 110 needs to be made of a smooth and flat glass material to ensure that subsequent layers can be uniformly and firmly attached to its surface.

[0042] Specifically, the adhesive layer 120 serves as a bonding and transition layer. By providing the adhesive layer 120 on the front side of the glass substrate 110, the adhesion between the glass substrate 110 and the colored pattern layer 130 is enhanced, ensuring that the colored pattern layer 130 is firmly attached to the glass substrate 110 and preventing it from detaching or peeling off during use. Furthermore, the adhesive layer 120 provides a relatively flat and uniform adhesion surface for the colored pattern layer 130, which is beneficial for improving the printing quality of the colored pattern and ensuring its clarity and color uniformity.

[0043] Specifically, by spraying a preset color pattern onto the adhesive liquid layer 120 to prepare a color pattern layer 130, the appliance panel 100 can have rich colors and personalized patterns, thereby meeting the aesthetic needs of different users for the appearance of the appliance.

[0044] Specifically, the PET film 140 is composed of a glass texture layer 142 and a functional coating 143 sequentially disposed on one side of the PET base film 141.

[0045] Specifically, the PET base film 141 serves as the foundation layer for the PET film 140, providing support and an adhesion surface for the glass texture layer 142 and the functional coating 143. The PET base film 141 possesses excellent mechanical, optical, and chemical properties, ensuring that the PET film 140 as a whole maintains a certain level of strength and flexibility, preserves good transparency, and does not affect the light transmission of the appliance panel 100 or the display effect of the colored pattern layer 130.

[0046] Specifically, by setting a glass texture layer 142 on the surface of the PET base film 141, the appliance panel 100 can be given the visual and tactile effects of glass, enabling the appliance panel 100 to produce rich light and shadow changes under light, and increasing the three-dimensionality and texture of the appliance panel 100.

[0047] Specifically, by providing a functional coating 143 to the glass texture layer 142, protection can be achieved for the glass texture layer 142, such as scratch resistance, fingerprint resistance, and antistatic properties. By facing the functional coating 143 toward the colored pattern layer 130 and pressing and curing it onto the colored pattern layer 130, a protective film can also be formed on the surface of the colored pattern layer 130, effectively preventing damage to the colored pattern layer 130 from external factors.

[0048] In this embodiment, a pre-set colored pattern layer 130 is formed by spraying a pre-set colored pattern onto the liquid layer 120 on the front side of the glass substrate 110 using inkjet printing technology. Compared to manual painting, this method allows for precise control of the pigment distribution in the colored pattern. The glass-like effect on the glass substrate 110 is formed by pressing and curing a PET film 140, on one side of which a glass texture layer 142 and a functional coating 143 are sequentially disposed, with the colored pattern layer 130. Compared to the process of preparing the glass texture layer 142 by high-temperature firing, this method eliminates the need for precise control of the high temperature, avoiding the problem of a deteriorated glass-like effect due to low precision in high-temperature control. Therefore, this embodiment can improve the quality of the glass-like effect of the appliance panel 100.

[0049] In some embodiments, the adhesion liquid layer 120 is prepared by coating the front side of the glass substrate 110 with an ink adhesion liquid; wherein, by mass percentage concentration, the ink adhesion liquid comprises: 1% to 10% functional acrylate, 0.5% to 8% adhesion promoter (e.g., mixed etherified urea resin, epoxy phosphate ester or modified polyester compound, etc.), 0.01% to 3% water-resistant agent (e.g., acrylic water-resistant agent or epoxy resin water-resistant agent), 0.01% to 2% acetic acid, 1% to 10% ethyl acetate, and solvents including water and / or ethanol.

[0050] Specifically, considering the relatively smooth surface of the glass substrate 110, directly printing a pre-defined colored pattern on the front side of the glass substrate 110 may be difficult to adhere firmly, easily leading to problems such as peeling and detachment. Therefore, in this embodiment, an adhesion layer 120 is prepared by coating the front side of the glass substrate 110 with an inkjet adhesion liquid. This effectively improves the physical and chemical properties of the front side of the glass substrate 110, allowing the pre-defined colored pattern to be printed subsequently to better bond with the glass substrate 110.

[0051] Specifically, the water in the solvent is deionized water, and the deionized water in the ink adhering solution has a mass percentage concentration of 1% to 10%, with the remainder being ethanol.

[0052] Combination Figure 3 As shown, this disclosure provides a method for preparing a home appliance panel, used to prepare the home appliance panel as described above. The preparation method includes:

[0053] S301, an ink adhesion liquid is coated on the front side of the cleaned glass substrate, and the substrate is left to stand for a set time to form an adhesion liquid layer.

[0054] Understandably, when the surface of the glass substrate contains impurities such as dust, oil, and fingerprints, it will affect the adhesion between the base ink and the glass substrate, leading to problems such as peeling and flaking of the screen-printed ink layer, resulting in an uneven and flawed surface on the manufactured appliance panel. Therefore, it is necessary to use a cleaned glass substrate.

[0055] Alternatively, the glass substrate can be cleaned as follows: use a 70% to 75% alcohol solution and a lint-free cloth to wipe the glass surface in a straight or spiral motion; after wiping, allow it to air dry naturally or use an air dryer to dry it quickly.

[0056] Specifically, by coating the front side of the glass substrate with an ink adhesion liquid and allowing it to stand for a set time to prepare the adhesion liquid layer, a transition layer can be formed between the glass substrate and the colored pattern layer. This enhances the adhesion of the colored pattern layer to the front side of the glass substrate, allowing the colored pattern to be better fixed on the glass substrate and preventing the pattern from falling off or peeling during use.

[0057] Specifically, ink coating liquid can be applied to the front side of the glass substrate using coating methods such as spraying, scraping, and spin coating. Among them, spraying can make the coating liquid evenly distributed on the front side of the glass substrate; scraping is suitable for situations where the coating thickness is more precise; spin coating involves placing the glass substrate on a rotating platform, dropping the ink coating liquid onto the center of the glass substrate, and then rotating it to make the coating liquid spread evenly.

[0058] Optionally, a glass ink adhering liquid may be coated on the front side of the cleaned glass substrate, including spraying the ink adhering liquid or wiping it onto the front side of the glass substrate with a non-woven cloth.

[0059] Optionally, the duration can be set to 5 to 10 minutes.

[0060] Specifically, the set duration can be 5 minutes, 6 minutes, 7 minutes, 8 minutes, 9 minutes, or 10 minutes.

[0061] S302, a preset colored pattern is sprayed onto the adhesive liquid layer to form a colored pattern layer.

[0062] Specifically, the preset color pattern is a pattern generated according to the user's needs.

[0063] Specifically, a pre-set color pattern is printed onto the adhesive layer using a printing machine. Before printing, the pre-set color pattern generated according to the user's requirements needs to be input into the control system of the printing machine. Then, appropriate ink colors and printing parameters, such as printhead pressure and printing speed, are selected according to the requirements of the pre-set color pattern. During the printing process, it is important to ensure that the distance between the printhead and the adhesive layer is appropriate to ensure that the ink is accurately sprayed onto the designated location.

[0064] S303, a PET film having a glass-textured layer and a functional coating sequentially disposed on one side.

[0065] Specifically, a PET film is prepared by sequentially preparing a glass-textured layer and a functional coating on one side of a PET base film (polyethylene terephthalate material).

[0066] Specifically, the glass-like texture layer is a textured structure similar to glass formed on the surface of a PET base film. By preparing the glass-like texture layer, the visual and tactile effects of glass can be given to the appliance panel, enabling the appliance panel to produce rich light and shadow changes under light, and increasing the three-dimensionality and texture of the appliance panel.

[0067] Specifically, by preparing functional coatings, the glass texture layer can be protected, for example, by preventing scratches, fingerprints, and static electricity.

[0068] S304, the functional coating of the PET film is pressed and cured towards the colored pattern layer to obtain the appliance panel.

[0069] Specifically, by pressing and curing the functional coating of the PET film towards the colored pattern layer, the PET film and the colored pattern layer can be tightly bonded together to form a whole. The pressing and curing process can enhance the adhesion between the layers, ensuring that the PET film will not fall off or separate during use, while also ensuring that the appliance panel has a flat and beautiful appearance.

[0070] Optionally, the PET film can be imprinted onto the colored pattern layer of the glass substrate using hot pressing or cold pressing. Hot pressing involves placing the PET film and the glass substrate with the colored pattern layer in a heated mold, maintaining it at a set temperature and pressure for a period of time to melt and fully fuse the adhesive between the functional coating and the colored pattern layer, followed by cooling and curing. Cold pressing applies a larger set pressure at room temperature, causing the layers to bond tightly together through mechanical interlocking and intermolecular forces.

[0071] In this embodiment, the liquid layer on the front side of the glass substrate is formed by spraying a preset colored pattern onto the glass substrate using inkjet printing technology. Compared to manual painting, this method allows for precise control of the pigment distribution in the colored pattern. The glass-like effect on the glass substrate is achieved by pressing and curing a PET film with a glass-like texture layer and a functional coating sequentially disposed on one side, together with the colored pattern layer. Compared to the process of preparing the glass-like texture layer by high-temperature firing, this method eliminates the need for precise control of the high temperature, avoiding the problem of a deteriorated glass-like effect due to low precision in high-temperature control. Therefore, this embodiment can improve the quality of the glass-like effect on the manufactured appliance panels.

[0072] Combination Figure 4 As shown in the embodiments of this disclosure, another method for preparing a home appliance panel is provided, the method comprising:

[0073] S401, an ink adhesion liquid is coated on the front side of the cleaned glass substrate, and the substrate is left to stand for a set time to form an adhesion liquid layer.

[0074] S402, edit the first design file corresponding to the preset color pattern on the UV printer.

[0075] Specifically, the design file serves as the instruction basis for the UV printer to perform the printing operation, precisely defining key parameters such as the shape, size, color distribution, and resolution of the color pattern. By editing the first design file corresponding to the preset color pattern on the UV printer, the user's required preset color pattern can be converted into digital information that the UV printer can recognize and execute, ensuring that the final printed color pattern matches the preset color pattern.

[0076] S403 enables the UV printer to operate according to the first design file, spraying colored UV ink onto the adhesion liquid layer to form a colored pattern layer.

[0077] In the first design file, the color K value is less than or equal to 90.

[0078] Specifically, in the design file, K represents black (Key). If the K value is too high, the printed color pattern may appear dark and dull, affecting the vibrancy and clarity of the colors. Therefore, this embodiment limits the color K value to less than or equal to 90, i.e., 90 or below. This ensures that the printed color pattern has brighter and more vibrant colors, improving the visual effect of the appliance panel.

[0079] Specifically, by running the UV printer according to the first setting file, the UV printer can control the printhead to accurately spray colored UV ink onto the surface of the adhesive liquid layer according to the preset colored pattern. Then, the colored UV ink is irradiated by the ultraviolet light emitted by the UV lamp, so that the colored UV ink is quickly cured and dried, thereby forming a colored pattern layer on the adhesive liquid layer.

[0080] S404, a PET film having a glass-textured layer and a functional coating sequentially disposed on one side.

[0081] S405 involves pressing and curing the functional coating of a PET film toward the colored pattern layer to obtain an appliance panel.

[0082] In this embodiment, a first design file corresponding to a preset color pattern is edited in a UV printer, and the UV printer operates according to the first setting file to prepare a color pattern layer on the adhesive liquid layer. Compared with manual painting, this method allows for precise control of the pigment distribution in the color pattern, which is beneficial for improving the quality of the glass-like effect on appliance panels.

[0083] Combination Figure 5 As shown, the steps for preparing a PET film with a glass-like texture and a functional coating sequentially disposed on one side include:

[0084] S501: Lay the PET base film flat on the UV printer and fix it using the UV printer's adsorption function.

[0085] Specifically, the UV printer has an adsorption function. When the adsorption function is turned on, the UV printer's working platform will generate negative pressure to adsorb and fix the PET base film on the platform to ensure that the PET base film will not move or shift during subsequent printing and coating processes.

[0086] Optionally, the thickness of the PET base film is from 185 μm to 200 μm.

[0087] S502 involves spraying a pre-defined texture onto one side of a PET base film to form a glass-like texture layer.

[0088] Specifically, a UV printer can control the movement of the printhead and the amount of ink sprayed to spray UV ink onto the surface of a PET base film according to a preset texture. Under ultraviolet light, the UV ink cures rapidly, forming a glass-like texture layer with a glass-like tactile and visual effect.

[0089] S503 involves spraying AF coating liquid onto a glass-textured layer to form a functional coating, thereby obtaining a PET film with both a glass-textured layer and a functional coating.

[0090] Specifically, by uniformly spraying AF (Anti-Fingerprint) coating liquid onto the already formed glass-textured layer using a spraying device, a PET film with a glass-textured and functional coating can be obtained.

[0091] In this embodiment, a glass texture layer is formed by spraying a glass texture onto one side of a PET base film using a UV printer. Compared to the process of preparing a glass texture layer by high-temperature firing, it eliminates the need for precise control of the high temperature, avoiding the problem of poor glass effect caused by low precision in high-temperature control, and improving the quality of the glass effect on home appliance panels.

[0092] In some embodiments, a preset texture is sprayed onto one side surface of a PET base film to form a glass-like texture layer, including: editing a second design file corresponding to the preset texture on a UV printer; causing the UV printer to run according to the second design file to spray a set number of transparent UV inks onto the surface of the PET base film to form a glass-like texture layer; wherein, in the second design file, the black K value is greater than or equal to 90, and the gray K value is greater than or equal to 50.

[0093] Specifically, the design file serves as the instruction basis for the UV printer's printing operation, precisely defining key parameters such as the texture's shape, size, color distribution, and resolution. By editing a second design file corresponding to the preset texture on the UV printer, the user's desired preset texture can be converted into digital information that the UV printer can recognize and execute, ensuring that the final printed glass-like texture layer matches the preset texture.

[0094] Specifically, black is used in glass textures to enhance the three-dimensionality and layering of the texture. A higher black K value can highlight the details and contours of the glass texture, creating a more realistic glass effect. Therefore, in the second design document of this disclosure, the black K value is limited to greater than or equal to 90.

[0095] Specifically, gray is used for transition and harmonization in glass textures, enabling different colors to blend more naturally and avoiding harsh color boundaries. A higher gray K value can increase the brightness and saturation of gray, making the transition smoother and more delicate, and enhancing the overall texture of the glass texture. Therefore, in the second design document of this disclosure, the gray K value is limited to greater than or equal to 50.

[0096] Specifically, the number of layers of transparent UV ink sprayed onto the surface of the PET base film is determined according to the tactile intensity corresponding to the preset texture; the stronger the tactile intensity, the more layers are set.

[0097] Optionally, when the tactile intensity corresponding to the preset texture is less than or equal to the set tactile intensity, the number of layers is set to 3 to 5; when the tactile intensity corresponding to the preset texture is less than or equal to the set tactile intensity, the number of layers is set to 8 to 10.

[0098] Combination Figure 6 As shown in the figure, this disclosure provides a method for preparing a home appliance panel, the method comprising:

[0099] S601, an ink adhesion liquid is coated on the front side of the cleaned glass substrate, and the substrate is left to stand for a set time to form an adhesion liquid layer.

[0100] S602, a preset colored pattern is sprayed onto the adhesive liquid layer to form a colored pattern layer.

[0101] S603, a PET film having a glass-textured layer and a functional coating sequentially disposed on one side.

[0102] S604 involves placing a PET film with a glass-like texture layer and a functional coating into an imprinting machine, and then imprinting the colored pattern layer onto it using UV resin.

[0103] S605 uses ultraviolet light irradiation for curing to obtain appliance panels.

[0104] The working pressure of the pressure roller in the embossing machine is 40 to 60 kg / cm². 2 The mercury lamp illumination intensity is 400 to 800 W / in, and the curing time is 8 to 16 seconds.

[0105] In this embodiment, the glass-like effect on the glass substrate is achieved by placing a PET film with a glass-like texture layer and a functional coating on an imprinting machine, imprinting it onto a colored pattern layer using UV resin, and then curing it with ultraviolet light. Compared to the process of preparing the glass-like texture layer by high-temperature firing, this method eliminates the need for precise control of the high temperature, avoiding the problem of a deteriorated glass-like effect due to low precision in high-temperature control, and thus improving the quality of the glass-like effect on appliance panels.

[0106] CombinationFigure 7 As shown in the figure, this disclosure provides a method for preparing a home appliance panel, the method comprising:

[0107] S701 uses 75% alcohol and a lint-free cloth to wipe the glass surface using either a straight or spiral wiping method.

[0108] S702, after wiping, use an airflow dryer to dry quickly.

[0109] S703: Apply ink adhesion liquid to the front side of the cleaned glass substrate and let it stand for 8 minutes to form an adhesion liquid layer.

[0110] S704, edits the first design file corresponding to the preset color pattern on the UV printer.

[0111] S705 enables the UV printer to operate according to the first design file, spraying colored UV ink onto the adhesion liquid layer to form a colored pattern layer.

[0112] S706: Lay the PET base film flat on the UV printer and fix it using the UV printer's adsorption function.

[0113] S707 allows editing of a second design file corresponding to a preset texture on a UV printer.

[0114] S708 enables the UV printer to run according to the second design file, spraying a set number of layers of transparent UV ink onto the surface of the PET base film to form a glass-like texture layer.

[0115] S709 involves spraying AF coating liquid onto a glass-textured layer to form a functional coating, thereby obtaining a PET film with both a glass-textured layer and a functional coating.

[0116] S710, adjust the working pressure of the pressure roller of the printing press to 60 kg / cm. 2 The intensity of the mercury lamp illumination was adjusted to 800W / in, and the PET film with the glass texture layer and functional coating was placed in the printing press and printed onto the colored pattern layer by UV resin molding.

[0117] S711 uses ultraviolet light to cure for 16 seconds to obtain home appliance panels.

[0118] In this embodiment, a pre-set colored pattern layer is formed by spraying a pre-defined colored pattern onto the liquid layer on the front side of the glass substrate using inkjet printing technology. Compared to manual painting, this method allows for precise control of the pigment distribution in the colored pattern. The glass-like effect on the glass substrate is achieved by pressing and curing a PET film with a glass-like texture layer and a functional coating sequentially disposed on one side, together with the colored pattern layer. Compared to the process of preparing the glass-like texture layer through high-temperature firing, this method eliminates the need for precise control of the high temperature, avoiding the problem of a deteriorated glass-like effect due to low precision in temperature control. Therefore, this embodiment of the present disclosure can improve the quality of the glass-like effect on the prepared appliance panels.
