Description

Technical Field

[0001] This application relates to the field of wall panel technology, specifically to an antibacterial and mildew-resistant bamboo and wood fiber integrated wall panel. Background Technology

[0002] Bamboo and wood fiber integrated wall panels are a type of green and environmentally friendly decorative material made from plant fibers such as bamboo powder and wood powder as the main raw materials, mixed with high-molecular resin and then extruded at high temperature. Due to their advantages such as convenient installation and beautiful appearance, they have been widely used in interior decoration. When existing bamboo and wood fiber wall panels are used for a long time in damp and poorly ventilated environments (such as bathrooms, kitchens, basements, etc.), bacteria and mold easily grow on their surface. This not only causes black spots and mold on the surface of the wall panels, affecting their appearance, but also releases harmful spores, polluting indoor air and endangering human health. At the same time, their interior is easily eroded by moisture, making them prone to damage. Therefore, this application proposes an antibacterial and mildew-resistant bamboo and wood fiber integrated wall panel to improve this problem. Utility Model Content

[0003] The purpose of this application is to provide an antibacterial and mildew-resistant bamboo and wood fiber integrated wall panel in order to solve the problems mentioned in the background art.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figures 1-4As shown, this application discloses an antibacterial and mildew-resistant bamboo and wood fiber integrated wall panel in some embodiments, comprising: a mounting base 1 on which a bamboo and wood fiber core board 2 is disposed; the mounting base 1 is used for installation with a wall surface or with an installation component disposed on the wall surface; a photocatalytic coating 3 is disposed on the bamboo and wood fiber core board 2; a plurality of cavities 4 are arrayed and penetrated on the bamboo and wood fiber core board 2; the cavities 4 are filled with desiccant particles 5; preferably, a supporting base layer is disposed on the surface of the bamboo and wood fiber core board 2; the photocatalytic coating is disposed on the supporting base layer to form the photocatalytic coating 3; the supporting base layer and the mounting base 1 sandwich the bamboo and wood fiber core board 2 in the middle, so that the cavities 4 can serve as receiving cavities, which are filled with desiccant particles 5; preferably, the photocatalytic coating 3 is made of nano-titanium dioxide, which absorbs photons when irradiated by ultraviolet light or visible light with sufficient energy, thereby generating oxygen. The chemical and reduction reactions can indiscriminately decompose organic matter on its surface, including bacteria, viruses, mold spores, and VOCs such as formaldehyde. It is responsible for killing and decomposing, and is an active purification layer. By filling the cavity 4 with desiccant particles 5 in the bamboo and wood fiber core board 2, the wall panel no longer relies solely on blocking external moisture, but gains the ability to actively intervene in and regulate its own internal environment. The desiccant particles 5 will continuously adsorb water vapor from the wall panel joints, the back, or slowly seep in through the material itself. Since the growth of mold requires nutrients, suitable temperature, and a liquid water film, the adsorption of water vapor by the desiccant particles 5 directly destroys the conditions for the formation of a water film, maintaining the humidity of the core area of ​​the bamboo and wood fiber core board 2 at a low level where mold cannot grow. At the same time, it can also prevent the bamboo and wood fiber core board 2 from being corroded and damaged by water vapor, and extend its service life. In this solution, the photocatalytic coating 3 can effectively sterilize and antibacterial the wall panel surface under the action of light, and treat the biological pollution on the wall panel surface. The bamboo and wood fiber core board 2 is filled with desiccant particles 5 through the cavity 4 to maintain the dryness and cleanliness of the wall panel inside, creating a physical environment that is not suitable for the survival of microorganisms. The self-cleaning of the surface and the drying of the inside complement each other, thereby improving the antibacterial and mildew-proof performance of the wall panel and extending its service life.

[0017] like Figure 3 and Figure 4As shown, this application discloses a further technical solution for the photocatalytic coating 3. The photocatalytic coating 3 has a plurality of micropores 6 arranged in an array, each micropore 6 corresponding to a plurality of cavities 4. By opening micropores 6 on the photocatalytic coating 3, preferably, the micropores 6 are micron-sized pores. These micropores 6 are small enough to prevent dust and liquid water from entering, but allow water vapor molecules to pass through slowly. When the indoor environment is humid, water vapor in the air will enter the cavity 4 through these micropores 6 and be captured by the desiccant particles 5. When the indoor environment becomes dry (e.g., when an air conditioner or dehumidifier is turned on), the moisture absorbed by the desiccant particles 5 will be slowly released through these micropores 6 and return to the air, thereby realizing the passive regeneration of the desiccant particles 5. At the same time, the micropores 6 ensure that the photocatalytic coating 3 does not completely seal the cavity 4, avoiding the cavity 4 from becoming a dead space due to the coating coverage. Meanwhile, light and air can also enter through the micropores 6, which helps to keep the cavity 4 dry and clean.

[0018] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the bamboo and wood fiber core board 2. The bamboo and wood fiber core board 2 is provided with a reinforcing layer 7. The reinforcing layer 7 adopts a grid-like support structure formed by a number of longitudinal ribs and a number of transverse ribs connected together. By setting the reinforcing layer 7, the wall panel's resistance to bending, impact and creep (deformation under long-term stress) is greatly enhanced, making the wall panel more robust and durable and less prone to deformation. At the same time, its grid-like structure can avoid the cavity 4 and does not affect its internal adsorption and dehumidification.

[0019] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the bamboo and wood fiber core board 2. A buffer layer 8 is provided between the bamboo and wood fiber core board 2 and the mounting substrate 1. The material of the buffer layer 8 is polystyrene foam. Polystyrene foam is made of polystyrene resin as the main body and additives such as foaming agents are added. It is not only lightweight, but also has good buffering performance, which can improve the compression and impact resistance of the bamboo and wood fiber core board 2.

[0020] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the buffer layer 8. Several grooves 9 are arrayed and penetrated on the buffer layer 8, and rock wool 10 is filled in the grooves 9. By opening grooves 9 on the buffer layer 8 and filling the grooves 9 with rock wool 10, the rock wool 10 is an inorganic fiber made by high-temperature melting and fiberization. Rock wool 10 has a low density and is lightweight. Without affecting the pressure-resistant buffering effect on the wall panel, the porous structure of rock wool 10 has a good sound absorption effect, which can effectively reduce the transmission of noise, thereby improving the overall sound insulation and noise reduction performance of the wall panel.

[0021] like Figure 4 As shown, this application discloses a further technical solution for the groove 9. The longitudinal section of the groove 9 is triangular, and two adjacent grooves 9 are staggered. The staggered arrangement of two adjacent grooves 9 results in an upper and lower stacked structure, which allows some noise to pass through the stack during transmission. The oblique stacked reflection of the inner wall of the groove 9 further improves the sound insulation and noise reduction performance. At the same time, the staggered distribution can further improve the pressure resistance and buffering effect and increase the service life of the wall panel when the weight is greatly reduced.

[0022] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the mounting substrate 1. The mounting substrate 1 is constructed with a frame 11, and the bamboo and wood fiber core board 2 and the buffer layer 8 are both located within the frame 11. By constructing the frame 11, the side seams between the layers of the wall panel can be wrapped and covered, which not only improves the overall aesthetic and protective performance of the wall panel, but also improves the overall strength of the wall panel, thereby improving its practicality.

[0023] like Figure 3 and Figure 4 As shown, this application discloses a further technical solution for the wall panel. The inner walls of the mounting base plate 1 and the frame 11 are provided with a waterproof membrane 12. In cold regions, the wall may produce condensation due to the temperature difference between the inside and outside. This waterproof membrane 12 can effectively prevent condensation from directly contacting and corroding the wall panel, ensuring the dryness of the core part of the wall panel.

[0024] The above description of the disclosed embodiments enables those skilled in the art to make or use this application. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this application. Therefore, this application is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
