[0026] The present invention will now be described in further detail with reference to the accompanying drawings, so that those skilled in the art can implement it based on the description.

[0027] To achieve the above objectives, refer to Figures 1-2 The present invention provides a prefabricated composite decorative wall panel, including a composite wall panel 1, wherein a decorative styling layer 2 is connected to one side of the composite wall panel 1 by a keel assembly.

[0028] As an optional implementation, the composite wall panel 1 includes a fireproof core material layer 11 and a first reinforcing plate 12 and a second reinforcing plate 13 disposed on both sides of the fireproof core material layer 11. The fireproof core material layer 11 can be made of fire-resistant thick rock wool that meets the requirements and is cut according to the design dimensions. The cut thick rock wool blocks are neatly arranged together and pressed using a dedicated pressing device to form a fireproof core material layer 11 with a certain thickness and density.

[0029] Apply environmentally friendly adhesive to both sides of the fireproof core material layer 11, then place the first reinforcing plate 12 and the second reinforcing plate 13 on the adhesive on both sides, and press them gently with your hand or a special tool so that the first reinforcing plate 12 and the second reinforcing plate 13 are tightly bonded to the fireproof core material layer 11.

[0030] Optionally, in some embodiments of this utility model, both the first reinforcing plate 12 and the second reinforcing plate 13 can be made of 8mm to 12mm fiber-reinforced silicate board. Fiber-reinforced silicate board has advantages such as high strength, water resistance, fire resistance, and moisture resistance, effectively improving the structural strength and stability of the composite wall panel 1. The thickness of the reinforcing plate ranges from 8mm to 12mm. In this embodiment, the fiber-reinforced silicate board is 9mm thick and symmetrically arranged on both sides of the fireproof core layer 11.

[0031] Fireproof core layer 11 is 100mm thick rock wool with a density of 100kg / m³. 3 .

[0032] The keel assembly includes interlocking embedded keels 3 and keel connectors 4. The keel connectors 4 are fixedly mounted on the back of the decorative layer 2, and the embedded end of the embedded keel 3 is completely covered within the fireproof core material layer 11. Through the detachable connection between the embedded keel 3 and the keel connectors 4, the keel connectors 4 are installed on the embedded keel 3, thereby enabling the decorative layer 2 to be installed on the composite wall panel 1.

[0033] First, compared with the traditional method of adding independent keel to the exterior wall panels, this technology reduces the overall weight of the exterior wall and the thickness of the entire exterior wall, so that the building area does not exceed the area index requirements of the State Grid's general design due to the shape.

[0034] Secondly, the integrated panel technology enables the integrated construction of steel structure building maintenance walls and shapes. The entire structure can be produced in the factory, and only assembly and connection are required on site, which reduces the difficulty of construction.

[0035] Optionally, in this embodiment, both the embedded keel 3 and the keel connector 4 have a hollow internal structure to reduce the weight of the keel assembly. Reinforcing ribs can be provided inside the embedded keel 3 to enhance the stability of the embedded keel 3.

[0036] Optionally, in this embodiment, the keel connector 4 is an elastic buckle. The embedded keel 3 is provided with a locking block 31 that works with the elastic buckle. Align the keel connector 4 on the decorative layer 2 with the embedded keel 3, and gently force the keel connector 4 into the embedded keel 3 so that the locking block 31 is fully embedded in the elastic buckle, ensuring a firm connection. At the same time, the elastic buckle can be pressed to disengage the locking block 31 from the keel connector 4, enabling quick disassembly of the decorative layer.

[0037] It should be noted that the keel connector 4 in this embodiment is provided with an elastic buckle, and the embedded keel 3 is provided with a locking block 31 that works in conjunction with the elastic buckle. The installation of the embedded keel 3 and the keel connection is achieved by the cooperation of the elastic buckle and the locking block 31. This is only one optional implementation method in this embodiment. In other embodiments, bolts or welding can also be used to achieve the installation of the embedded keel 3 and the keel connection.

[0038] As an optional implementation, the decorative layer 2 of this embodiment includes a plurality of decorative panels 21 to facilitate the handling of the decorative layer 2. At the same time, any two adjacent decorative panels 21 are bonded together by a sealant layer 22 to enhance the sealing effect between the two adjacent decorative panels 21.

[0039] The surface of the composite wall panel 1 away from the decorative panel 21 is laminated with a paint-free decorative panel 14, which can meet different decorative needs. The paint-free panel does not require painting, which not only saves construction time and costs, but also avoids the pollution of the indoor environment caused by paint volatilization, thus meeting environmental protection requirements.

[0040] Optionally, the paint-free decorative panel 14 in this embodiment can be a cement fiber paint-free board with a fire rating of Class A and a thickness of 5mm. The paint-free board and the composite wall panel 1 are tightly bonded together with the reinforcing board through a hot-pressing process.

[0041] Apply an appropriate amount of adhesive to the surface of the second reinforcing plate 13 on the side away from the decorative layer 2, and then cover the paint-free decorative panel 14 onto the reinforcing plate. Hot pressing can be performed using a hot press. The hot pressing temperature is controlled at 120-150℃, the pressure is 0.5-1.0MPa, and the hot pressing time is 3-5 minutes to ensure a firm bond between the paint-free panel and the reinforcing plate.

[0042] Optionally, in some embodiments of the present invention, the surface of the composite wall panel 1 near the decorative layer 2 is coated with a waterproof coating 15.

[0043] The waterproof coating uses polyurethane, which has excellent waterproof performance and flexibility, effectively preventing moisture from penetrating into the composite wall panel 1. Before applying the waterproof coating, the surface of the reinforcing board is cleaned and treated to ensure that the coating adheres evenly. The waterproof coating is applied in 1-2 mm thick coats, typically 2-3 coats, to ensure a good waterproof effect.

[0044] Optionally, in some embodiments of the present invention, an aluminum foil covering 16 is provided between the fireproof core material layer 11 and the second reinforcing plate 13.

[0045] The fire-resistant core material layer 11 has an aluminum foil covering 16 on the side away from the decorative layer 2. The aluminum foil covering 16 is made of pure aluminum foil with a thickness of 0.02-0.05mm. Aluminum foil has good heat insulation and fire resistance properties, which can further improve the fire resistance of the composite wall panel 1, and also play a certain role in moisture protection. The aluminum foil covering 16 is tightly bonded to the fire-resistant core material layer 11 by adhesive. During the bonding process, it is necessary to ensure that the surface of the aluminum foil is flat and free of bubbles and wrinkles.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. It is obvious to those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and that the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
