Description

Technical Field

[0001] This utility model relates to the field of flame-retardant wall panel technology, and in particular to a novel antibacterial flame-retardant wall panel. Background Technology

[0002] Fire-retardant wall panels are essential functional materials in modern building decoration, primarily used to improve the fire safety level of buildings. They are widely used in public places, high-rise buildings, and areas with special fire protection requirements. Their core function is to slow the spread of fire through their non-combustible or flame-retardant properties, buying valuable time for evacuation and fire fighting.

[0003] However, many existing flame-retardant wall panels are relatively simple in design and function, often focusing on achieving basic flame-retardant performance and lacking inherent integration such as antibacterial and anti-mildew properties. In terms of materials and structure, common solutions are mostly single homogeneous materials or simple multi-layer pressing, sacrificing lightweight characteristics to achieve sufficient strength, becoming bulky and unbearable. Or their flame-retardant performance depends on surface treatment, and once the surface layer is damaged, the flame-retardant ability is greatly reduced. For example, a current wall panel might use ordinary perlite or rock wool as internal filling to provide thermal insulation and fire retardancy. However, this material itself is prone to moisture absorption and mold growth, lacks antibacterial properties, and ordinary perlite has limited fire retardancy, its protective effect rapidly diminishing when exposed to intense fire. While this type of wall panel possesses some fire resistance, it has significant shortcomings in hygiene and safety, structural stability, and overall performance, failing to meet the ever-increasing demands for high-standard buildings. Utility Model Content

[0004] This utility model discloses a novel antibacterial and flame-retardant wall panel, which aims to solve the technical problems of existing flame-retardant wall panels lacking inherent antibacterial and anti-mildew properties; sacrificing lightweight characteristics in materials and structure, becoming bulky, and relying on surface treatment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel antibacterial and flame-retardant wall panel includes an outer frame, with fixing strips on the front and rear edges of the outer frame, an inner frame fixedly connected inside the outer frame, a honeycomb sheet fixedly connected inside the inner frame, the honeycomb sheet being filled with a filler, a partition layer on the outside of the honeycomb sheet, an outer panel on the outside of the partition layer, and a slot on the edge of the outer panel.

[0006] By employing the above technical solution, perlite treated with zinc borate solution is filled into the hexagonal chambers of aluminum honeycomb sheets, and combined with the inner and outer wire mesh partitions and glass fiber reinforced magnesium oxide outer plate, achieving a synergistic and multifunctional effect. The aluminum honeycomb sheets, as the core skeleton, with their unique high specific strength structure, significantly reduce the overall weight of the wall panel while providing a stable and uniformly distributed space for the filler, ensuring the structural rigidity of the wall panel. The perlite filler, after being treated with zinc borate, is functionalized, retaining not only its lightweight, heat-insulating, and Class A non-combustible properties, but also endowed with the highly efficient flame-retardant and antibacterial / mildew-inhibiting activities of zinc borate, thus giving the core layer of the wall panel an inherent and long-lasting dual function of flame retardancy and antibacterial properties. The outer wire mesh partition tightly connects the honeycomb core material and the magnesium oxide outer plate into a whole, effectively preventing peeling of the layers under heat or impact, greatly enhancing the crack resistance and integrity of the wall panel.

[0007] As a further embodiment of this utility model: the outer panel is made of glass fiber reinforced magnesium oxide board, the size of the outer panel is the same as the internal size of the outer frame, the outer panel is attached to the outside of the partition, and there are two layers of both the partition and the outer panel. The two layers of the partition and the outer panel are symmetrically arranged on the front and back sides of the honeycomb sheet. When the fixing strip is bent, it can be completely embedded in the slot, and when the fixing strip is bent, it is on the same plane as the outside of the outer panel. The gap between the fixing strip and the slot is filled with glue.

[0008] By adopting the above technical solution, a robust, aesthetically pleasing, and airtight connection between the exterior decorative panel and the internal load-bearing frame is achieved. A completely concealed fixing system is formed by using flexible fixing strips located on the edge of the outer frame and engaging with the grooves on the edge of the outer panel. During assembly, the fixing strips are bent and embedded into the grooves. The elastic deformation of the metal components generates a continuous locking force, thus firmly fixing the fire-resistant magnesium oxide outer panel to the base surface composed of the inner frame and partition. This mechanical locking mechanism, working in conjunction with the adhesive, ensures both the reliability of the connection and the integrity of the fire-resistant performance of the outer panel. The fixing strips, after bending, are flush with the surface of the outer panel, creating a smooth appearance without exposed fasteners and eliminating the thermal bridging effect that can occur with traditional metal connectors. Finally, the gaps between the fixing strips and the grooves are filled with adhesive, further enhancing the airtightness of the connection and effectively preventing the penetration of moisture, air, and dust. This improves the overall airtightness, watertightness, and durability of the wall panel while maintaining aesthetics.

[0009] In summary, this application includes at least one of the following beneficial technical effects: 1. It achieves an inherent unity between a lightweight and high-strength structural foundation and efficient and long-lasting flame-retardant and antibacterial functions. By filling the aluminum honeycomb skeleton with perlite treated with zinc borate, and reinforcing it on both sides with wire mesh partitions and magnesium oxide outer panels, the core performance of the wall panel and its long-term safety and hygiene are ensured.

[0010] 2. It achieves a firm mechanical locking between the fireproof outer panel and the internal frame. Its completely concealed design ensures connection reliability while maintaining the fireproof integrity of the outer panel and the flatness and aesthetics of the wall surface, and effectively improves the edge sealing performance.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Reference Figures 1 to 4 A novel antibacterial and flame-retardant wall panel includes an outer frame 1, with fixing strips 2 on the front and rear edges of the outer frame 1, an inner frame 3 fixedly connected inside the outer frame 1, a honeycomb sheet 4 fixedly connected inside the inner frame 3, a filler 5 inside the honeycomb sheet 4, a partition 6 on the outside of the honeycomb sheet 4, an outer panel 7 on the outside of the partition 6, and a slot 8 on the edge of the outer panel 7.

[0019] Specifically, the aluminum honeycomb skeleton serves as the supporting core, and its regularly arranged hexagonal lattice ensures structural strength while achieving effective weight reduction. The lattice is tightly filled with perlite impregnated with zinc borate solution. When heated, this composite material can form a heat insulation barrier through the decomposition of zinc borate, enhancing the flame-retardant and smoke-suppressing effect, while also providing long-lasting antibacterial and anti-mildew properties. The wire mesh partitions 6 on both sides of the core layer tightly connect the filling material to the honeycomb skeleton, preventing interlayer delamination and ensuring uniform load transfer. The outer magnesium oxide board, together with the internal functional layers, constitutes a complete fireproof system.

[0020] The outer frame 1 and the fixing strip 2 are both made of iron material coated with an anti-rust layer. The anti-rust layer can prevent the outer frame 1 from rusting and ensure the strength of the outer frame 1. The inner frame 3 is made of stainless steel with an internal cavity, which achieves lightweight while ensuring support strength. The fixing strip 2 and the inner frame 3 are fixed to the surface of the outer frame 1 by welding. The fixing strip 2 is thin and can be bent.

[0021] Among them, the honeycomb sheet 4 is made of aluminum and has a regular hexagonal shape. The cavity between the inner frames 3 is filled with the honeycomb sheet 4. The regular hexagonal structure can provide the best structural strength and stability with the lightest weight. The filler 5 is perlite. Before filling, the perlite is treated by impregnating with zinc borate solution, upgrading it from a traditional heat insulation filler material to a functional core material with both high-efficiency flame retardancy and long-lasting antibacterial function. The partition 6 is wire mesh. The edge of the partition 6 is fixedly connected to the inside of the outer frame 1 by welding.

[0022] Reference Figures 1 to 3 In a preferred embodiment, the outer panel 7 is made of glass fiber reinforced magnesium oxide board, the size of the outer panel 7 is the same as the internal size of the outer frame 1, and the outer panel 7 is attached to the outside of the partition 6.

[0023] Specifically, by using the flexible bending fixing strip 2 on the edge of the outer frame 1 and the pre-set groove 8 on the edge of the outer panel 7, the fixing strip 2 is bent and fully embedded in the groove 8 during installation. The elastic deformation of the metal material generates a continuous lateral locking force, thereby firmly pressing the outer panel 7 onto the internal frame. The end of the bent fixing strip 2 is flush with the surface of the outer panel 7, forming a concealed connection without exposed fasteners. Finally, sealant is filled into the gap between the fixing strip 2 and the groove 8, which not only enhances the stability of the mechanical fixation but also achieves a complete seal at the connection.

[0024] The partition layer 6 and the outer panel 7 are both two layers. The two layers of partition layer 6 and outer panel 7 are symmetrically arranged on the front and back sides of the honeycomb sheet 4. The symmetrical design keeps the structure and performance of the wall panel in balance, giving the wall panel double-sided protection.

[0025] When the fixing strip 2 is bent, it can be fully embedded in the slot 8, and when the fixing strip 2 is bent, it is on the same plane as the outer side of the outer panel 7. The elastic deformation of the metal provides a strong connection force, while avoiding exposed fasteners, thus achieving a flat and beautiful wall surface visual effect. The gap between the fixing strip 2 and the slot 8 is filled with glue, eliminating the gap at the connection point and significantly improving the air tightness, water tightness and sound insulation performance of the wall panel edge.

[0026] Working Principle: The core structure uses internal aluminum honeycomb sheets 4, whose regularly arranged hexagonal cells provide excellent compressive and bending strength while achieving significant weight reduction. The honeycomb sheets 4 are tightly filled with filler 5 treated with zinc borate solution, allowing the core material to retain its inherent heat and sound insulation properties. Furthermore, the thermal decomposition of zinc borate creates a heat barrier, giving the wall panel the dual functions of active flame retardancy, smoke suppression, and long-lasting antibacterial properties. The partitions 6 on both sides of the core layer tightly connect the honeycomb sheets 4, filler 5, and outer panel 7 into a unified whole, effectively... To prevent interlayer delamination and ensure uniform load distribution, the outer glass fiber reinforced magnesium oxide board not only provides a wear-resistant and weather-resistant surface, but also forms a double fire barrier with the inner functional layer. In terms of installation and connection, the flexible fixing strip 2 on the edge of the outer frame 1 is precisely bent and embedded into the corresponding slot 8 of the adjacent wall panel 7. The continuous locking force generated by the metal deformation is used to achieve mechanical connection between the panels. Then, the gaps are filled with sealant, and finally a complete wall solution is formed that integrates structural stability, high-efficiency fire resistance, long-lasting antibacterial properties, high-quality sealing and beautiful decoration.

[0027] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
