[0046] A first aspect of the embodiments of this utility model provides a composite plate 50, such as Figures 1 to 2 As shown, where, Figure 1 A schematic diagram of the structure of the composite plate 50 according to an embodiment of the present invention is shown. Figure 2 for Figure 1 The exploded structural diagram of the composite panel 50 shown indicates that the composite panel 50 includes a substrate layer 51, a magnetic adsorption layer 54, a decorative component 56, and a curing layer 57. The magnetic adsorption layer 54 is connected to the substrate layer 51 and is a magnetic material layer or a material layer that can be magnetically attracted by a magnetic substance. The decorative component 56 is stacked on the side of the magnetic adsorption layer 54 away from the substrate layer 51 and is connected to the magnetic adsorption layer 54. The curing layer 57 is stacked on the side of the decorative component 56 away from the substrate layer 51 and is connected to the decorative component 56.
[0047] It should be noted that the decorative component 56 here includes a multi-layer structure, which makes the composite panel 50 more aesthetically pleasing. Furthermore, the magnetic adsorption layer 54 can be a layer of magnetic material, such as a soft magnet, hard magnet, or rubber magnet in powder, sheet, or block form. For example, the magnetic adsorption layer 54 can be a sheet-like hard magnet, as hard magnets can maintain their magnetism for a long time and are not prone to demagnetization, thus extending the service life of the magnetic composite panel 50. Alternatively, the magnetic adsorption layer 54 can also be a material layer that can be magnetically attracted by magnetic materials, and can be in powder, sheet, or block form, such as sheet metal or iron. Specifically, sheet metal can be used for the magnetic adsorption layer 54, as it is rust-resistant and corrosion-resistant, which can extend the service life of the composite panel 50.
[0048] It should be added that the magnetic adsorption layer 54 here can also be a plastic film material containing magnets or materials that can be magnetically attracted by magnetic substances, which can also have a magnetic attraction effect and can be magnetically attracted to magnetic refrigerator magnets.
[0049] Continue to refer to Figure 1 As shown, in Figure 1 In the diagram, the XX direction represents the width of the composite panel 50, and the ZZ direction represents its thickness. The cured layer 57 is located on the outermost side of the composite panel 50. The decorative component 56 is positioned between the cured layer 57 and the substrate layer 51 along the thickness direction of the composite panel 50, thus enhancing the aesthetics of the composite panel 50. The cured layer 57 not only serves an aesthetic purpose but also provides strength and impact resistance, thereby protecting the composite panel 50 and improving its impact resistance and mechanical strength.
[0050] The composite panel 50 of this utility model comprises a substrate layer 51, a magnetic adsorption layer 54, a decorative component 56, and a curing layer 57. The magnetic adsorption layer 54 is connected to the substrate layer 51 and is a magnetic material layer or a material layer that can be magnetically attracted by a magnetic substance. The decorative component 56 is stacked on the side of the magnetic adsorption layer 54 away from the substrate layer 51 and is connected to the magnetic adsorption layer 54. The curing layer 57 is stacked on the side of the decorative component 56 away from the substrate layer 51 and is connected to the decorative component 56. Thus, the magnetic refrigerator magnet can be attached to the surface of the composite panel 50 through the magnetic force between the magnetic adsorption layer 54 and the magnetic refrigerator magnet, without affecting the aesthetics and safety of the composite panel 50, thereby improving the consumer experience.
[0051] Optionally, such as Figure 1 and Figure 2 As shown, the decorative component 56 includes a base color layer 561 and a pattern layer 562 that are stacked and interconnected. The base color layer 561 is connected to the magnetic adsorption layer 54, and the pattern layer 562 is a transparent or semi-transparent structure. The base color layer 561 is a pigment layer, which can be wood grain color or other colors. The pattern layer 562 can have a wavy pattern or other patterns. The pattern layer 562 covers part of the surface of the base color layer 561, and the pattern layer 562 and the base color layer 561 can match each other, which can increase the aesthetics of the decorative component 56.
[0052] Optionally, the decorative component 56 further includes a transparent or semi-transparent reinforcing layer 563. The reinforcing layer 563 is stacked on the side of the patterned layer 562 opposite to the base color layer 561 and connected to the patterned layer 562. The reinforcing layer 563 can be made of a material with good transparency and gloss, which can improve the appearance quality of the composite panel 50. Furthermore, the reinforcing layer 563 can also improve the impact resistance of the composite panel 50 and significantly enhance its toughness.
[0053] Optionally, the reinforcing layer 563 includes one of PET and PETG components. The PET component possesses high transparency, excellent temperature resistance, high mechanical strength, high rigidity, good wear resistance, high chemical stability, environmental friendliness, and excellent processing performance. The PETG component possesses high transparency, good optical properties, excellent impact resistance, chemical corrosion resistance, environmental friendliness, and excellent processing performance. Therefore, including either PET or PETG components in the reinforcing layer 563 can improve the impact resistance of the composite board 50 and enhance its aesthetics.
[0054] It is understandable that the reinforcing layer 563 here can also be made of other plastic parts with high transparency, such as polycarbonate parts, which will not be listed here.
[0055] Optionally, the curing layer 57 is a transparent or semi-transparent structure, and the curing layer 57 is connected to the reinforcing layer 563. The curing layer 57 and the reinforcing layer 563 are stacked. The curing layer 57 is located outside the reinforcing layer 563. That is, the curing layer 57 is located on the outer surface of the composite board 50 along the thickness direction, so that the user can observe the surface of the reinforcing layer 563 through the curing layer 57, which increases the aesthetics of the composite board 50.
[0056] Optionally, the curing layer 57 includes one of an ultraviolet curing layer 57, a thermosetting layer 57, and an infrared curing layer 57. The ultraviolet curing layer 57 is a protective film formed on the surface of the composite board 50 using an advanced UV (Ultraviole) treatment process. This protective film is mainly composed of modified polyurethane, an environmentally friendly and non-toxic organic polymer material with excellent adhesion, dimensional stability, mildew resistance, and enhanced wear and impact resistance, thereby improving the wear and impact resistance of the composite board 50.
[0057] The thermosetting layer 57 here is obtained by using heat to cause the curing agent to react and the coating to polymerize. The thermosetting layer 57 can be made of transparent thermosetting resin materials, such as polypropylene, polycarbonate, nylon, polyetheretherketone and polyethersulfone. These materials will undergo a chemical reaction and solidify when heated to form a solid that no longer melts, thus obtaining a transparent thermosetting layer 57.
[0058] The infrared curing layer 57 here is formed by irradiating the coating with infrared rays. The energy radiated onto the composite board 50 is absorbed and converted into heat, thereby obtaining a cured coating, which is the infrared curing layer 57.
[0059] It is understandable that the cured layer 57 here can also be obtained by other curing methods, which will not be illustrated here.
[0060] Optionally, the PVC layer 512 and the magnetic adsorption layer 54 are connected together by heat sealing, adhesive bonding, magnetic attraction, riveting, or embedding. Heat sealing utilizes heat energy to heat the plastic material above its melting point, softening it, and then applies pressure to firmly connect two or more components together. In other words, the PVC layer 512 and the magnetic adsorption layer 54 can be connected by heat sealing. Adhesion refers to bonding the PVC layer 512 and the magnetic adsorption layer 54 together using adhesive. Specifically, a first adhesive layer 53 can be provided between the PVC layer 512 and the magnetic adsorption layer 54, connecting them through the first adhesive layer 53. Magnetic attraction refers to connecting the PVC layer 512 and the magnetic adsorption layer 54 using magnetic attraction. Riveting refers to connecting the PVC layer 512 and the magnetic adsorption layer 54 using riveting. Embedding refers to connecting the PVC layer 512 and the magnetic adsorption layer 54 by embedding.
[0061] Optionally, a paint layer 52 is provided on the surface of the substrate board 511 facing away from the PVC layer 512. The paint layer 52 is located on the innermost side of the composite board 50 along the thickness direction, which can play a role in preventing corrosion and improving aesthetics.
[0062] Optionally, the magnetic adsorption layer 54 and the base color layer 561 are connected together by heat sealing, adhesive, magnetic attraction, riveting or fitting. When the magnetic adsorption layer 54 and the base color layer 561 are connected by adhesive, a second adhesive layer 55 can be provided. That is, the connection between the magnetic adsorption layer 54 and the base color layer 561 is achieved by the second adhesive layer 55.
[0063] Optionally, continue to refer to Figure 1 and Figure 2 As shown, the cured layer 57 and the reinforcing layer 563 are connected together by heat sealing, adhesive bonding, magnetic attraction, riveting, or fitting. When the cured layer 57 and the reinforcing layer 563 are connected by adhesive bonding, this can be achieved by providing a third adhesive layer 564. That is, the connection between the cured layer 57 and the reinforcing layer 563 is achieved through the third adhesive layer 564.
[0064] Optionally, the substrate layer 51 includes a substrate board 511 and a PVC layer 512 stacked and interconnected, wherein the PVC layer 512 is connected to the magnetic adsorption layer 54. The PVC layer 512 can be connected to the substrate layer 51 using a modern hot-press bonding process, thereby improving the connection efficiency between the substrate board 511 and the PVC layer 512.
[0065] Optionally, the substrate board 511 includes an SPC board, wherein the SPC board is a stone-plastic composite material, which is a new type of composite material formed by extruding stone powder and PVC resin under high temperature and high pressure. The stone powder is made from natural stone through multiple processes such as crushing, screening, and pulverizing, while the PVC resin is an environmentally friendly plastic with good weather resistance, corrosion resistance, sound insulation and fire resistance.
[0066] During the production of composite board 50, the first adhesive layer 53, magnetic adsorption layer 54, second adhesive layer 55, decorative component 56 and curing layer 57 can be combined into a roll film structure. When the substrate layer 51 is extruded, the roll film and the substrate layer 51 are hot-pressed online to form the composite board 50 structure, which improves efficiency, significantly reduces cost, and avoids the low bonding efficiency and high defect rate of block boards.
[0067] It should be noted that in the conventional production process of composite board 50, the substrate layer 51 is first extruded and shaped into a fixed length, then the magnetic adsorption layer 54 and decorative component 56 are pre-produced, then adhesive is applied to the substrate layer 51 and the magnetic adsorption layer 54 is flatly attached, cured, then the decorative component 56 is applied and cured, and finally the edges are cut and ground. This production process is complex, has a low yield, and is costly. The production process of this utility model, by online hot-pressing the roll film and the substrate layer 51 into the structure of composite board 50, can significantly improve the production efficiency of composite board 50 and reduce its cost.

The refrigerator compartment is located above the freezer compartment, in which case the refrigerator door 11 is located above the freezer door 12.
[0072] Continue to refer to Figure 3 As shown, the display and control panel 13 is fixed to the refrigerator door 11 by an embedded installation method. Alternatively, the display and control panel 13 can also be set on the freezer door 12.
