Description

Technical Field

[0001] This utility model belongs to the field of decorative materials technology, specifically relating to a wall panel structure with high stain resistance, suitable for interior wall decoration in home decoration. Background Technology

[0002] Currently, commonly used materials for interior wall decoration in homes and public spaces include wallpaper, wall coverings, diatomaceous earth, and ordinary decorative wall panels. However, these materials cannot simultaneously achieve "decorativeness, ease of installation, and stain resistance," and still have the following drawbacks:

[0003] (1) Wallpaper and wall coverings: The wall needs to be leveled first, and they are sensitive to environmental humidity (suitable humidity is 40%-60%, and excessive humidity can easily cause mold and peeling); after the surface is stained (such as soy sauce or oil pen marks), wiping can easily cause surface damage or stains to remain, which are not easy to clean and have poor durability. Their service life is usually only 3-5 years.

[0004] (2) Diatomaceous earth: The colors are mainly solid colors and simple textures, which are relatively limited and the range of choices is narrow; construction requires professional personnel to use the "scraping + texture shaping" process, which is expensive and 2-3 times that of ordinary wall panels; and its porous structure easily absorbs dust and oil stains, and it cannot be wiped with water or detergent when cleaning, but can only be wiped dry, which has limited stain resistance.

[0005] (3) Ordinary decorative wall panels, although they can achieve a variety of colors through surface coating (such as PVC film, PET film), the film layer does not have a special stain-resistant coating. After the surface is stained, it needs to be wiped with a cleaning agent containing chemical reagents, which can easily cause the film layer to fade and lose its gloss. In addition, some products use MDF substrate, which poses a risk of formaldehyde release and is difficult to meet the high cleanliness requirements.

[0006] While some wall panels in the current technology use UV-cured films, these films are mostly three-layer structures consisting of a substrate layer, a printing layer, and a UV-cured layer. The UV-cured layer is a common epoxy acrylate system with a surface hardness of only 1H-2H, resulting in poor stain resistance. Therefore, there is an urgent need for a wall panel that combines decorative versatility, ease of installation, environmental friendliness, and high stain resistance. Summary of the Invention

[0007] In view of the problems of poor stain resistance, complicated installation and insufficient environmental protection of existing wall decoration materials, the purpose of this utility model is to disclose a highly stain-resistant wall panel that achieves advantages such as high stain resistance, moisture and mildew resistance, fire and water resistance and formaldehyde-free environmental protection through structural design and material optimization.

[0008] Technical solution

[0009] A highly stain-resistant wall panel includes a solid core panel body, a flat surface solid portion, a flat back solid portion, and a UV excimer functional film, wherein:

[0010] The solid wall panel body is made of wood-plastic composite material, with a width of 600±1mm or 1200±1mm and a thickness of 9±0.2mm, and can be freely grooved at both ends;

[0011] The flat surface solid part is the outer side of the solid core wall panel body, which is covered with a UV excimer functional film.

[0012] The flat back solid part is the inner side of the solid wall panel body. The surface has no film and can be directly connected to the interior wall by nails, nail-free adhesive or clips. No fine leveling of the wall is required during installation.

[0013] The UV excimer functional film has a thickness of 0.14±0.01mm and a hardness of ≥2H. It is composed of a PVC base layer, a printed layer, a wear-resistant layer, and a UV excimer protective layer stacked sequentially in the order of "PVC base layer → printed layer → wear-resistant layer → UV excimer protective layer".

[0014] In a preferred embodiment of this utility model, the groove is 8mm-10mm wide and 4mm-5mm deep. The groove is used for splicing between wall panels and is connected by snap-fit ​​or mortise and tenon structure.

[0015] In a preferred embodiment of this utility model, the PVC base layer is a rigid PVC material with a thickness of 0.06mm-0.08mm and a tensile strength ≥25MPa, providing physical strength and structural stability for the functional membrane;

[0016] The printed layer is a UV ink printing and curing layer with a thickness of 0.02mm-0.03mm, used to present the base color and display the finishing color;

[0017] The wear-resistant layer is made of transparent polyvinyl chloride resin with a thickness of 0.03mm-0.04mm. It is fused with the printed layer through high temperature and high pressure, and its wear resistance reaches "wear amount ≤5mg / 1000 revolutions", preventing surface scratches.

[0018] The UV excimer protective layer is formed by UV curing of modified polyurethane, with a thickness of 0.01mm-0.02mm, a smooth surface, and stains are not easy to adhere to and are easy to remove.

[0019] Beneficial effects

[0020] The high stain-resistant wall panel disclosed in this utility model has a wood-plastic composite substrate that is moisture-proof, mildew-proof, fireproof, waterproof, formaldehyde-free, and environmentally friendly; the UV excimer functional film has high hardness and high stain resistance, and stains such as oil-based pens can be wiped clean without chemical reagents; the structure is simple and the installation is convenient, meeting the dual requirements of home decoration for cleanliness and decoration.
