[0002] Wood composite board is a common man-made board. Its production process includes crushing, drying, batching, gluing and other processes of wood shavings or fiber materials, and then pressing them under high temperature and high pressure. Wood composite board has the advantages of solid texture, smooth surface and not easy to deform. It is widely used in furniture manufacturing, building decoration, packaging boxes and other fields. Compared with solid wood boards, wood composite boards have the advantages of low cost, stable quality and easy processing, so they have been widely used and recognized in the market.

[0003] The existing wood-plastic composite board through grooves are provided with nano-silver antibacterial structures to increase the mildew and antibacterial properties of the composite board, and a drying structure is provided inside the composite board to achieve water absorption and moisture resistance to prevent mildew. For example, Chinese patent publication number CN216380009U discloses "a mildew-proof and antibacterial wood-plastic composite board", which improves the antibacterial and antibacterial ability of the wood board through nano-silver antibacterial boards, improves the water absorption and moisture resistance of the wood board through water-absorbing and moisture-proof columns provided inside the mildew-proof cylindrical grooves, removes odors on the surface of the wood board with activated carbon boards, utilizes the clamping effect between the vertical clamping slots and the vertical solid wood plug boards to splice the lower antibacterial device and the upper wear-resistant device, and cooperates with sealing rubber boards to improve the sealing of the clamping;

[0004] In actual use, since the composite panels are usually made of multiple composite panels spliced ​​together to form floors and laid indoors, moisture will still seep into the gaps, and since the water-absorbing and moisture-proof columns are not connected to the joints of the composite panels, the moisture at the joints of the composite panels is adsorbed for a longer time, causing the joints of the composite panels to easily become moldy and breed bacteria.

[0008] A corrosion-resistant plate is fixedly arranged on the top plate, and a nano-silver antibacterial layer is arranged on the upper end of the corrosion-resistant plate and the lower end of the base plate.

[0009] Furthermore, a connection groove is formed on the outer wall of the substrate, and the substrate is wrapped with an edge that matches the connection groove, and the edge is a metal layer.

[0010] Furthermore, the corrosion-resistant plate and the top plate are staggered, extension plates are formed on both sides of the corrosion-resistant plate, and the top plate and the corrosion-resistant plate cooperate to form a connecting portion.

[0013] Furthermore, the desiccant is a silica gel particle desiccant or a lime powder desiccant.

[0014] The utility model provides a mildew-proof and antibacterial wood-plastic composite board, which has the following beneficial effects:

[0015] In the utility model, the columnar activated carbon in the through hole is connected to the side of the composite board, and cooperates with the desiccant in the groove to dry the joint of the composite board, so as to quickly absorb the moisture at the joint of the composite board and prevent mold and bacteria from growing;

[0016] Secondly, in the utility model, a nano-silver antibacterial layer is provided on the upper end of the corrosion-resistant plate and the lower end of the substrate to prevent the upper and lower end surfaces of the composite plate from mold and bacteria, and a connecting groove is opened on the outer wall of the substrate, and the substrate is hemmed with a metal layer to slow down the corrosion rate of the substrate and increase the service life of the substrate.
