Description

Technical Field

[0001] This utility model relates to the field of wallpaper, specifically a dustproof and dirt-resistant wallpaper. Background Technology

[0002] As people's living standards improve, their demands for home decoration are also increasing. Wallpaper, as a common wall decoration material, is widely welcomed due to its aesthetic appeal and comfort. However, traditional wallpaper faces some problems in practical use that urgently need to be addressed:

[0003] Dust and dirt resistance issues: Ordinary wallpaper easily attracts dust, and stains are difficult to clean once they appear. Especially in high-traffic areas such as living rooms and dining rooms, the wallpaper surface quickly becomes dirty with dust and stains, affecting its appearance. This not only increases the workload of daily cleaning, but frequent cleaning can also cause wear and tear on the wallpaper, shortening its lifespan. For example, in households with children or pets, handprints, footprints, or pet scratches and stains easily remain on the wallpaper, making cleaning very difficult.

[0004] Insufficient antibacterial properties: As home decorations used for extended periods, wallpaper is prone to the growth of bacteria, mold, and other microorganisms under suitable temperature and humidity conditions. These microorganisms not only produce unpleasant odors and affect indoor air quality but may also pose a threat to human health, especially for the elderly, children, and people with allergies who have weakened immune systems. For example, in humid southern regions, mold growth on wallpaper is quite common, affecting not only aesthetics but also potentially releasing harmful spores. Therefore, we have proposed a dust-resistant and stain-resistant wallpaper. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a dustproof and dirt-resistant wallpaper, which solves the above-mentioned problems.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a dustproof and dirt-resistant wall covering, comprising a hydrophobic surface layer, an antibacterial layer, a base layer, and an adhesive layer, wherein the hydrophobic surface layer is disposed on the surface of the antibacterial layer, the antibacterial layer is disposed on the surface of the base layer, and the base layer is disposed on the surface of the adhesive layer.

[0007] Preferably, the surface hydrophobic layer is a composite film or a hydrophobic coating.

[0008] Preferably, the antibacterial layer includes a layer and a fiber layer, wherein the layer is either cotton fiber or hemp fiber, and is woven from cotton fiber or hemp fiber and then embroidered onto the fiber layer.

[0009] Preferably, the fiber layer is woven from multiple groups of bamboo fibers and presents a V-shaped weave.

[0010] Preferably, the base layer is non-woven fabric or paper base.

[0011] Preferably, the bonding layer includes a rubber sheet, and the rubber sheet is bonded to the base layer with adhesive.

[0012] Preferably, multiple sets of hexagonal holes are equidistantly formed on the rubber flexible plate.

[0013] Compared with the prior art, this utility model provides a dustproof and dirt-resistant wallpaper with the following beneficial effects:

[0014] 1. This dust-proof and stain-resistant wallpaper features a hydrophobic surface layer, whether a composite film or a hydrophobic coating, giving it strong water-repellent properties. When dust and stains come into contact with liquid, the liquid quickly forms droplets and rolls off, carrying away some of the dust and making it difficult for stains to adhere. This significantly reduces dust accumulation and stain adhesion on the wallpaper surface, requiring only simple wiping to maintain cleanliness, reducing cleaning costs and workload, and extending the wallpaper's aesthetic lifespan.

[0015] 2. This dustproof and dirt-resistant wall covering features a hydrophobic coating formed by polytetrafluoroethylene and other high-molecular polymer films and nanoparticles, which has high stability and can maintain a low surface energy state during long-term use, effectively resisting various pollutants and ensuring that the wall covering maintains a good dustproof and dirt-resistant effect for a long time.

[0016] 3. This dust-proof and stain-resistant wallpaper features an antibacterial layer made of cotton or linen fiber, and a fiber layer made of bamboo fiber. These natural fibers inherently possess antibacterial properties. The combination of multiple natural antibacterial fibers comprehensively and effectively inhibits the growth of bacteria, mold, and other microorganisms, creating a healthy indoor air environment and protecting the health of residents. It is especially suitable for places with high hygiene requirements, such as hospitals, schools, and homes, effectively inhibiting microbial growth and eliminating odors caused by microbial reproduction at the source, keeping the indoor air fresh and improving living comfort.

[0017] 4. This dustproof and stain-resistant wallpaper features a rubberized adhesive layer with excellent flexibility and elasticity. Once bonded to the substrate, it significantly enhances the overall resistance to deformation. When faced with uneven wall surfaces or external forces, the rubberized adhesive layer effectively disperses stress, preventing damage caused by excessive localized stress and improving the wallpaper's durability.

[0022] 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, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-3 A dustproof and dirt-resistant wall covering includes a surface hydrophobic layer 1, an antibacterial layer, a base layer 4, and an adhesive layer 5. The surface hydrophobic layer 1 is disposed on the surface of the antibacterial layer, the antibacterial layer is disposed on the surface of the base layer 4, and the base layer 4 is disposed on the surface of the adhesive layer 5.

[0024] Furthermore, the surface hydrophobic layer 1 is a composite film or a hydrophobic coating. The composite film is a thin film with hydrophobic properties that is bonded to the wallpaper. This film can be made of a polymer material, such as polytetrafluoroethylene. It is bonded to the wallpaper through a specific process to give the wallpaper surface a hydrophobic function. The hydrophobic coating is made by uniformly coating hydrophobic nanoparticles on the surface of the wallpaper to form a dense and extremely thin hydrophobic coating.

[0025] Furthermore, the antibacterial layer includes layer 2 and fiber layer 3. Layer 2 is made of either cotton or linen fiber. Layer 2 is mainly used to display the pattern of the wallpaper. It is made of cotton or linen fiber woven into threads and then embroidered onto fiber layer 3.

[0026] Furthermore, the fiber layer 3 is woven from multiple groups of bamboo fibers 6, and it presents a V-shaped weave.

[0027] Furthermore, the base layer 4 can be made of non-woven fabric or paper. Non-woven fabric is made from polyester fiber, viscose fiber, etc., through non-woven processes such as needle punching and hydroentangling. It is lightweight, soft, and has good breathability, allowing the wall to breathe freely and effectively preventing mold and yellowing. At the same time, the non-woven fabric base layer adheres well to the wall, making construction convenient and greatly reducing the risk of wallpaper blistering and curling. Paper base is usually made of natural wood pulp, with relatively low cost. Paper-based base layers have good adaptability for wallpaper printing, and can present a rich variety of colors and exquisite patterns. However, its moisture resistance is relatively weak, and moisture-proofing treatment is required when used in high humidity environments. If non-woven fabric is used for base layer 4, it is made of polyester fiber, viscose fiber, etc., and is lightweight and soft, which not only facilitates construction but also has excellent breathability. This allows the walls to breathe freely, effectively preventing mold and yellowing caused by moisture buildup, extending the lifespan of both the wall covering and the wallpaper. It also enhances the adhesion between the wallpaper and the wall, reducing bubbling and curling, and improving the overall decorative effect. When the base layer is paper-based, its relatively low cost due to its natural wood pulp provides consumers with a more cost-effective option. Furthermore, paper-based wallpaper is highly adaptable to printing, allowing for a rich variety of colors and exquisite patterns to meet the personalized decorative needs of different consumers. Although its moisture resistance is weak, it can still exert its decorative advantages when properly treated for moisture control.

[0028] Furthermore, the bonding layer 5 includes a rubber flexible sheet 7, and the rubber flexible sheet 7 is bonded to the base layer 4 with adhesive. The rubber flexible sheet 7 can increase the overall resistance to deformation.

[0029] Furthermore, multiple sets of hexagonal holes 8 are equidistantly opened on the rubber flexible board 7. When this wallpaper needs to be laid, the glue is evenly applied to the surface of the rubber flexible board 7, and then filled into the interior of the hexagonal holes 8 before being glued to the wall. This can increase the filling area of ​​the glue and enhance the adhesive effect.

[0030] Structural Description:

[0031] Surface hydrophobic layer 1

[0032] Function: It gives the wallpaper the key functions of dust resistance and dirt resistance, effectively preventing moisture, dust and stains from adhering to the surface of the wallpaper, making the wallpaper easier to clean and keeping it clean for a long time.

[0033] Types and principles:

[0034] Composite film: This involves bonding a thin film made of a high-molecular polymer material (such as polytetrafluoroethylene) with the wallpaper using a specific process. Polytetrafluoroethylene has extremely low surface energy, making it difficult for water and other liquids to spread on its surface. Instead, water droplets form and roll off, thus preventing stains from penetrating into the wallpaper and achieving a hydrophobic and stain-resistant effect.

[0035] Hydrophobic coating: Hydrophobic nanoparticles are uniformly coated onto the surface of the wallpaper to form a dense and extremely thin coating. The small size effect and special surface properties of the nanoparticles create a micro-rough structure, which, combined with their low surface energy, significantly increases the contact angle between the liquid and the wallpaper surface, achieving highly efficient hydrophobicity.

[0036] The antibacterial layer includes layer 2 and fiber layer 3.

[0037] Layer 2:

[0038] Material: Made from either cotton or linen fiber. Both of these natural fibers have antibacterial properties and are naturally sourced, making them environmentally friendly and healthy.

[0039] Function: Primarily used to display the patterns on wallpaper. By spinning cotton or linen fibers into threads and then embroidering them onto fiber layer 3, exquisite patterns are formed, adding decorative value to the wallpaper.

[0040] Fiber layer 3:

[0041] Material: Woven from multiple layers of bamboo fiber. Bamboo fiber itself has natural antibacterial, bacteriostatic, anti-mite, and deodorizing properties, which further enhance the antibacterial effect of the antibacterial layer. At the same time, bamboo fiber also has good breathability, moisture absorption, and a soft feel.

[0042] Weaving method: V-shaped weave. This weaving method increases the structural strength and stability of the fiber layer, making it less prone to deformation or damage when subjected to external forces such as stretching and friction during daily use of the wallpaper. It also helps to enhance the overall texture of the wallpaper.

[0043] Grassroots 4

[0044] Function: As a supporting structure for wallpaper, it plays a key role in the stability, durability, and construction performance of the wallpaper.

[0045] Materials and features:

[0046] Non-woven fabric: Made from polyester fiber, viscose fiber, and other raw materials through non-woven processes such as needle punching and hydroentangling. It is lightweight and soft, with excellent breathability, allowing walls to "breathe" and effectively preventing mold and yellowing caused by moisture buildup. It adheres well to walls, is easy to install, and greatly reduces the risk of bubbling or curling during use.

[0047] Paper-based wallpaper: Typically made from natural wood pulp, it is relatively inexpensive. It adapts well to wallpaper printing, offering a rich variety of colors and exquisite patterns to meet the diverse decorative needs of consumers. However, its moisture resistance is relatively weak; in high-humidity environments, additional moisture-proofing measures are required to ensure the wallpaper's lifespan and performance.

[0048] The bonding layer 5 includes a rubber flexible sheet 7

[0049] Rubber flexible sheet 7:

[0050] Material and Function: Made of soft rubber sheet material, it has good flexibility and elasticity. It is bonded to the base layer 4 with adhesive, which can increase the overall resistance of the wallpaper to deformation, making the wallpaper more resilient when facing uneven wall surfaces or external forces, and less prone to damage due to localized stress.

[0051] Structural Design: Multiple sets of hexagonal holes 8 are evenly spaced on the rubber flexible board 7. During the wallpaper installation process, when adhesive is evenly applied to the surface of the rubber flexible board 7, the adhesive can fill the interior of the hexagonal holes 8, thereby increasing the contact area between the adhesive and the wall surface. This greatly improves the adhesion between the wallpaper and the wall surface, ensuring the wallpaper is firmly adhered to the wall and extending its service life.

[0052] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
