Description

Technical Field

[0001] This utility model relates to the field of composite board technology, specifically to a super scratch-resistant and stain-resistant functional composite board. Background Technology

[0002] With the rapid development of the home decoration, commercial space decoration, and furniture manufacturing industries, composite panels have been widely used in high-frequency usage scenarios such as dining tables, coffee tables, bathroom cabinets, and kitchen countertops. These panels are typically composed of a substrate layer and a functional layer, and have become the mainstream choice in the market. Especially in home and catering settings, users are increasingly demanding greater diversity in the appearance and ease of use of panels. Composite panels, with their customizable patterns and easy-to-clean features, have further expanded their application scope.

[0003] However, traditional composite panels still have significant performance shortcomings in practical use, making it difficult to meet the long-term durability requirements of high-frequency usage scenarios. The surface protective layer of most composite panels lacks sufficient hardness, making them prone to scratches, dents, and even surface cracks from scratches by keys, tableware, or accidental impacts from metal tools during daily use. This not only affects the appearance but also allows stains to penetrate the inner layer, shortening the panel's lifespan and forcing users to frequently replace them to maintain a good user experience, thus reducing the panel's structural stability and reliability.

[0004] To address these issues, we designed an ultra-scratch-resistant and stain-resistant functional composite board. Utility Model Content

[0005] The purpose of this invention is to provide a super scratch-resistant and stain-resistant functional composite board to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides an ultra-scratch-resistant and stain-resistant functional composite board, including a substrate, a first adhesive layer on one side of the substrate, a transition layer on one side of the first adhesive layer, an adhesive layer on one side of the transition layer, and a nano-ceramic layer on one side of the adhesive layer.

[0007] Furthermore, a second adhesive layer is provided on the other side of the substrate, and a moisture-proof layer is provided on the other side of the second adhesive layer.

[0008] Furthermore, the transition layer is internally provided with glass fiber.

[0009] Furthermore, a hydrophobic layer is provided on one side of the nano-ceramic layer.

[0010] Furthermore, the nano-ceramic layer is bonded to the transition layer by an adhesive layer.

[0011] Furthermore, the moisture-proof layer is bonded to the substrate by a second adhesive layer.

[0012] Furthermore, the substrate is solid wood board, particleboard, or chipboard.

[0013] Furthermore, the moisture-proof layer is made of epoxy backing paint.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By sequentially setting a first adhesive layer, a transition layer, an adhesive layer, a nano-ceramic layer, and a hydrophobic layer on one side of the substrate, the nano-ceramic layer is used to achieve scratch resistance, while the transition layer contains glass fiber to disperse the impact stress on the substrate and prevent the substrate from cracking; the hydrophobic layer makes stains easy to wipe through the "lotus effect", thus achieving the stain resistance of the substrate.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those of ordinary skill in the art without creative effort are all within the protection scope of the present utility model.

[0018] Please see Figure 1-4 This utility model provides a technical solution: including a substrate 1, a first adhesive layer 2 is provided on one side of the substrate 1, a transition layer 3 is provided on one side of the first adhesive layer 2, an adhesive layer 5 is provided on one side of the transition layer 3, a nano-ceramic layer 6 is provided on one side of the adhesive layer 5, and a hydrophobic layer 7 is provided on one side of the nano-ceramic layer 6. The nano-ceramic layer 6 is bonded to the transition layer 3 by the adhesive layer 5. The substrate 1 is a solid wood board, particleboard, or chipboard.

[0019] It should be noted that the first adhesive layer 2, the second adhesive layer 8, and the glue layer 5 serve as the "connecting carriers" for each functional layer, ensuring a stable bond in the multi-layer structure and preventing interlayer separation. The first adhesive layer 2 connects the substrate 1 to the transition layer 3, and the glue layer 5 connects the transition layer 3 to the nano-ceramic layer 6. Both adhesives are selected with good compatibility with the corresponding layer materials (such as modified epoxy). The layers are tightly bonded through intermolecular forces, and the peel strength is tested to be ≥1.5N / mm, effectively preventing interlayer separation and detachment caused by temperature and humidity changes, external impacts, and other factors during long-term use. The second adhesive layer 8, while connecting the substrate 1 to the moisture-proof layer 9, further strengthens the stability of the underlying structure, forming a "comprehensive connection system" together with the first adhesive layer 2 and the glue layer 5. This ensures that the substrate layer, transition layer, functional layer, and moisture-proof layer work synergistically, ultimately achieving a "reliable function and stable structure" for the entire board.

[0020] In practice, the nano-ceramic layer 6 is tightly bonded to the surface of the transition layer 3 via the adhesive layer 5. Its main components are nano-sized high-hardness ceramic particles (such as alumina and silicon dioxide), with a Mohs hardness of over 9H, far exceeding that of common scratch sources in daily use such as keys, tableware, and hard plastics (Mohs hardness 2-5H). When external scratching forces act on the surface of the board, the nano-ceramic layer 6 directly resists the scratches due to its high hardness, preventing the scratch source from damaging the surface and avoiding scratches, thus achieving a "super scratch-resistant" effect.

[0021] The nano-ceramic layer 6 is formed using a nano-particle sintering process, with interparticle gaps of only 50-100nm, creating a highly dense surface structure. This dense structure effectively prevents dust, oil, sauces, and other stains from embedding into the surface. Furthermore, the smooth surface of the nano-ceramic layer 6 ensures that stains can only adhere to the surface, preventing "penetrating adhesion" and laying the foundation for subsequent cleaning of the board. The hydrophobic layer 7 (such as a fluorosilane coating) on ​​the surface of the nano-ceramic layer 6 can significantly reduce the surface energy of the composite board, making the water contact angle ≥110° and the oil contact angle ≥90°. When liquid stains (such as soy sauce, cooking oil, and water stains) drip onto the composite board, the hydrophobic layer 7 can cause the stains to roll in a ball shape through the "lotus effect," preventing them from spreading and penetrating the surface. For solid stains such as dust and powder, due to the smooth surface and hydrophobicity, they can be easily removed by wiping with a dry cloth, ultimately achieving a "wipe clean" stain-resistant effect and reducing the difficulty of daily cleaning of the composite board.

[0022] See Figure 2 A second adhesive layer 8 is provided on the other side of the substrate 1, and a moisture-proof layer 9 is provided on the other side of the second adhesive layer 8. The moisture-proof layer 9 is bonded to the substrate 1 through the second adhesive layer 8, and the moisture-proof layer 9 is made of epoxy back paint.

[0023] By means of configuration, the moisture-proof layer 9 is made of epoxy backing paint, which is tightly adhered to the other side (non-functional layer side) of the substrate 1 through the second adhesive layer 8. After the epoxy backing paint is cured, it forms a continuous and seamless polymer film with a dense molecular structure, which can effectively block external moisture (such as kitchen condensate, bathroom moisture, and floor dampness) from penetrating from the back of the substrate 1, and prevent the substrate 1 from expanding and deforming due to moisture. The second adhesive layer 8 uses a high-adhesion, water-resistant adhesive (such as polyurethane adhesive). This ensures, on one hand, that there are no gaps between the moisture-proof layer 9 and the substrate 1, preventing moisture from seeping in through interlayer gaps; on the other hand, the water-resistant adhesive maintains stable adhesion even in humid environments, preventing the moisture-proof layer 9 from separating from the substrate 1. Combined with the structural characteristics of the substrate 1 (solid wood board, particleboard, or chipboard), the moisture-proof layer 9 significantly reduces the water absorption thickness expansion rate of the substrate 1, preventing the substrate from deforming or delaminating due to moisture, thus ensuring the structural stability of the board.

[0024] See Figure 3 The interior of the transition layer 3 is provided with glass fiber 4.

[0025] By setting a transition layer 3, the glass fibers 4 (usually 10-20μm in diameter) embedded inside the transition layer 3 play a key "toughness buffering" role: Since the nano-ceramic layer 6 has high hardness but poor toughness, if it is hit by a sharp heavy object (such as a metal tool falling), the glass fibers in the transition layer 3 can disperse the impact stress through their excellent toughness, avoiding problems such as cracking and chipping of the nano-ceramic layer 6 due to local stress concentration, further ensuring the integrity of the surface scratch-resistant structure and extending the service life of the board.

[0026] Working principle: When the device is in use, a first adhesive layer 2, a transition layer 3, an adhesive layer 5, a nano-ceramic layer 6, and a hydrophobic layer 7 are sequentially arranged on one side of the substrate 1. The nano-ceramic layer 6 provides scratch resistance, while the transition layer 3 contains glass fiber 4, which disperses the impact stress on the substrate 1 and prevents it from cracking. The hydrophobic layer 7, such as a fluorosilane coating, causes stains to roll in a ball shape through the "lotus effect," preventing them from spreading and penetrating the surface, making the stains easy to wipe and achieving the stain resistance of the substrate 1. At the same time, a moisture-proof layer 9 is provided. The moisture-proof layer 9 is made of epoxy backing material. The moisture-proof layer 9, together with the second adhesive layer 8, can prevent moisture from penetrating the substrate 1 to prevent deformation. The first adhesive layer 2, the adhesive layer 5, and the second adhesive layer 8 ensure that each layer is tightly bonded, ensuring the overall structural stability.

Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
