Description

Technical Field

[0001] This utility model relates to the field of bathroom wooden door technology, and in particular to a bathroom wooden door with moisture-proof and mildew-proof functions. Background Technology

[0002] In environments like bathrooms, which are frequently damp and exposed to high temperatures and humidity, traditional wooden doors face severe challenges. Ordinary wooden door cores (such as untreated solid wood, particleboard, or MDF) readily absorb moisture from the environment, causing the door to swell, warp, and crack, severely affecting the door's flatness, smoothness of opening and closing, and lifespan. Simultaneously, damp environments provide ideal conditions for the growth of mold and bacteria, easily leading to mold spots and unpleasant odors on the door's surface and interior, not only damaging its appearance but also potentially causing health problems.

[0003] Therefore, there is an urgent need to develop a special wooden door for bathrooms that has comprehensive, multi-layered, and long-lasting moisture-proof and mildew-proof functions, as well as a stable structure and tight sealing, in order to solve the above-mentioned technical pain points. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a bathroom wooden door with moisture-proof and mildew-proof functions.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bathroom wooden door with moisture-proof and mildew-proof functions includes:

[0007] The core layer of the door is made of high-density moisture-proof substrate, including moisture-proof particleboard, moisture-proof MDF, or solid wood board that has been treated with anti-corrosion.

[0008] A moisture-proof coating, applied to the surface of the door core layer, is composed of water-based polyurethane resin or epoxy resin, with a thickness of 0.1-0.3mm.

[0009] An anti-mildew and antibacterial layer is placed on the outside of the moisture-proof coating and contains nano silver ions or organic anti-mildew agents;

[0010] The decorative surface layer covers the anti-mildew and antibacterial layer, using natural wood veneer, PVC film or melamine finish, and the surface is coated with a waterproof UV paint layer;

[0011] The edge sealing structure, including aluminum alloy or ABS edge banding around the door leaf, is fixed by hot melt adhesive or ultrasonic welding to ensure that there are no water seepage gaps at the edges.

[0012] Preferably, the moisture-proof substrate of the door core layer is treated with high temperature and high pressure, and a waterproofing agent is added inside, with a water absorption rate of ≤8%.

[0013] Preferably, the coating process of the moisture-proof coating includes spraying, roller coating or impregnation, and after curing, a continuous and dense waterproof film is formed.

[0014] Preferably, the concentration of nano-silver ions in the anti-mildew and antibacterial layer is 50-200 ppm, or the organic anti-mildew agent is an isothiazolinone compound.

[0015] Preferably, the waterproof UV coating layer of the decorative surface layer has a thickness of 20-50μm, a gloss of 30-70°, and exhibits no bubbling or peeling after immersion in water for 24 hours in a water resistance test.

[0016] Preferably, the edge sealing strip of the edge sealing structure is 10-30mm wide, and the joint with the door leaf is filled with silicone sealant to form a double waterproof barrier.

[0017] Preferably, the bathroom wooden door also includes a ventilation structure, which is movably embedded in the bottom or top of the door leaf. The ventilation structure is hollow and filled with activated carbon or desiccant material. The outer wall of the ventilation structure is provided with densely distributed micro-ventilation holes with a diameter of 2-5mm and a spacing of 10-20cm to promote air circulation and reduce humidity.

[0018] Preferably, the outer wall of the ventilation structure is provided with a filling layer, which is a flexible sealing film or a rubber sealing strip. The filling layer fills the gap between the ventilation structure and the door leaf mounting groove, and the ventilation structure is squeezed and fixed by the sealing film or rubber sealing strip.

[0019] Preferably, a moisture-proof film is heat-applied to the outer wall of the decorative surface layer. The film is made of polyethylene (PE) or polypropylene (PP) film with a thickness of 0.05-0.1 mm.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. Core Material Protection: High-density moisture-proof substrate is used, and it is treated with high temperature and high pressure and waterproof agent is added, so that the core layer itself has an extremely low water absorption rate, which fundamentally resists the expansion and deformation caused by moisture intrusion. A moisture-proof coating composed of water-based polyurethane or epoxy resin is coated on the surface of the core layer to form a continuous and dense waterproof membrane, which effectively blocks the direct corrosion of liquid water and environmental moisture to the core material. Aluminum alloy or ABS edge banding strips are used in combination with hot melt adhesive / ultrasonic welding, and silicone sealant is filled at the joints to form a strong, durable, and seamless double waterproof sealing barrier, which completely solves the problem of water seepage at the edge of the door.

[0022] 2. Long-lasting anti-mildew and antibacterial effect: An anti-mildew and antibacterial layer is specially set on the outside of the moisture-proof coating. It contains 50-200ppm of highly effective antibacterial nano silver ions or isothiazolinone compounds, which can effectively kill or inhibit the growth of mold and bacteria on the surface and shallow layer of the door.

[0023] 3. Add a movable, embedded ventilation structure. The interior is hollow and filled with activated carbon or desiccant, and the outer wall has micro-ventilation holes. This can promote air circulation when needed, help reduce bathroom humidity, and reduce condensation.

[0024] In summary, this utility model, through its innovative multi-layer composite structure design and key material selection, particularly the core moisture-proof core material, dense moisture-proof coating, specially designed anti-mildew layer, tight edge sealing, and optional intelligent ventilation structure, achieves comprehensive and three-dimensional moisture-proof and mildew-proof protection for bathroom wooden doors from the inside out and from the core to the edges. This significantly improves the dimensional stability, structural durability, hygiene safety, and appearance durability of wooden doors in extremely humid environments. Attached Figure Description

[0035] Edge sealing structure 5 includes aluminum alloy or ABS edge sealing strips around the door leaf, which are fixed by hot melt adhesive or ultrasonic welding to ensure that there are no water seepage gaps at the edges.

[0036] The moisture-proof substrate of the core layer 1 is treated with high temperature and high pressure, and a waterproofing agent is added inside, with a water absorption rate of ≤8%.

[0037] The coating process of the moisture-proof coating 2 includes spraying, roller coating or impregnation, and after curing, it forms a continuous and dense waterproof film.

[0039] The waterproof UV coating of decorative layer 4 has a thickness of 20-50μm and a gloss of 30-70°. After immersion in water for 24 hours, there was no bubbling or peeling.

[0040] The edge sealing structure 5 has an edge strip width of 10-30mm, and the joint with the door leaf is filled with silicone sealant to form a double waterproof barrier.
