Description

Technical Field

[0001] This utility model belongs to the field of cabinet board technology, and in particular relates to a moisture-proof multi-layer cabinet board. Background Technology

[0002] Because cabinet boards are used in humid environments, excessive humidity can cause a series of problems, such as board expansion and deformation, board warping, seam cracking, doors not closing properly, drawers jamming, loose connections, delamination, reduced bending strength, bulging, cracking and peeling of the decorative layer, mold growth, accelerated formaldehyde release, corrosion and rusting of metal fittings, and reduced lifespan.

[0003] Current moisture-proofing measures for boards include selecting base materials, setting waterproof board finishes, setting edge sealing processes (weak points in moisture protection), setting aluminum foil interlayers, and setting edge drainage channels. However, problems with poor moisture-proofing still occur, and the boards cannot quickly absorb moisture after becoming damp. Summary of the Invention

[0004] The purpose of this utility model is to provide a moisture-proof multi-layer cabinet board. Through the design of the ventilation layer, the moisture can be accelerated to be discharged through air flow, which can actively remove moisture. It is equivalent to setting a ventilation interlayer inside the board that can carry away the moisture of the board, which greatly improves the humidity tolerance, improves the moisture resistance and service life of the board. Through the TPU edge banding design, the integrated edge banding is fused together, without seams and with good edge sealing, which improves the moisture-proof sealing ability of the edge of the board.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] The upper substrate layer has a waterproof layer on its upper surface, the lower substrate layer has a one-way breathable layer on its lower surface, and a ventilation layer is formed between the upper substrate layer and the lower substrate layer.

[0008] The ventilation layer includes a frame body, within which several vertical partitions are linearly arranged and divided into several sub-channels. Each sub-channel has a horizontal partition at both ends, which divides the sub-channel into a moisture absorption area and two confluence areas.

[0009] Several wavy dividing strips are provided between the two transverse partitions, and the several dividing strips divide the moisture absorption area into several channels. Several openings are provided on the transverse partitions, and the two ends of the channels are connected to two confluence areas through the openings.

[0010] The frame body has several through holes on both sides, and the several through holes are respectively connected to several busbar areas. A one-way valve is fixed at several through holes on one side of the frame body, and an outer sleeve is fixed at several through holes on the other side of the frame body. A miniature fan is fixed inside the outer sleeve.

[0011] The outer surfaces of the upper substrate layer, lower substrate layer, ventilation layer, waterproof layer, and one-way breathable layer are fused and fixed with TPU edging.

[0012] Furthermore, an embedding groove is provided on one side of the TPU edging, and a main guide line is provided in the embedding groove, with several of the micro fans connected in parallel to the main guide line.

[0013] Furthermore, the TPU edging is provided with clearance openings on both sides, and the outer sleeve and the one-way valve are both spaced within the clearance openings.

[0014] Furthermore, both the upper substrate layer and the lower substrate layer are multi-layered solid wood layers.

[0015] Furthermore, the waterproof layer is an aluminum foil layer or a PET composite film, and the outer surface of the waterproof layer is provided with a nano silver ion antibacterial coating.

[0016] Furthermore, the unidirectional breathable layer is a microporous silicone membrane.

[0017] This utility model has the following beneficial effects:

[0018] This invention, through the design of a ventilation layer, can accelerate the expulsion of moisture through airflow, enabling active dehumidification. It is equivalent to setting up a ventilated interlayer inside the board that can carry away the moisture from the board, which greatly improves the humidity tolerance, enhances the moisture resistance and service life of the board. Through the TPU edge-wrapping design, the integrated edge sealing is seamless and has good edge sealing, improving the moisture-proof sealing ability at the edge of the board.
