Description

Technical Field

[0001] This application relates to the field of flooring technology, and more specifically, to a low-odor, formaldehyde-free, safe flooring material. Background Technology

[0002] Vinyl flooring, also known as linoleum, is a type of flooring material. It is a rubber and plastic product and is an indispensable flooring material for power distribution rooms, substations, and communication equipment rooms. As people's living standards continue to improve, their requirements for the health and comfort of their living environment are increasing. As a widely used material for indoor floor decoration, the environmental performance of linoleum flooring has attracted much attention.

[0003] Existing vinyl flooring products present several problems: Firstly, some vinyl flooring products use large amounts of adhesives and additives containing volatile organic compounds (VOCs) during production, causing them to continuously release a pungent odor during use. This not only affects indoor air quality but may also harm human health, such as causing respiratory diseases and allergic reactions. Secondly, the widespread formaldehyde pollution problem in interior decoration materials cannot be ignored. Formaldehyde is a potent carcinogen and teratogen; long-term exposure to formaldehyde-containing environments can severely damage the human immune and nervous systems. Ordinary vinyl flooring often lacks effective formaldehyde-removing capabilities, failing to adsorb and decompose free formaldehyde in indoor air, thus failing to meet people's needs for a healthy living environment.

[0004] To address the aforementioned issues, this application provides a low-odor, formaldehyde-free, safe flooring material. Utility Model Content

[0005] The low-odor, formaldehyde-free, and safe flooring provided in this application adopts the following technical solution: A low-odor, formaldehyde-free, safe flooring material includes, from top to bottom, a wear-resistant surface layer, a formaldehyde-free functional layer, a cushioning and sound-insulating layer, and a moisture-proof base layer. The adjacent layers of the wear-resistant surface layer, the formaldehyde-free functional layer, the cushioning and sound-insulating layer, and the moisture-proof base layer are bonded together with an environmentally friendly adhesive.

[0006] Furthermore, the wear-resistant surface layer is made of a composite material of polyvinyl chloride and nano-silica, the thickness of the wear-resistant surface layer is 0.3-0.8mm, and the surface has an anti-slip microstructure.

[0007] Furthermore, the formaldehyde-removing functional layer includes a core layer composed of activated carbon fiber felt loaded with nano-titanium dioxide, and an upper chitosan polymer film and a lower chitosan polymer film located on the upper and lower sides of the activated carbon fiber felt loaded with nano-titanium dioxide. The activated carbon fiber felt loaded with nano-titanium dioxide has a thickness of 0.5-1.0 mm, and the upper chitosan polymer film and the lower chitosan polymer film each have a thickness of 0.1-0.3 mm.

[0008] Furthermore, the nano-titanium dioxide in the activated carbon fiber felt loaded onto the surface of the activated carbon fiber felt through adsorption and chemical bonding.

[0009] Furthermore, the sound insulation layer is made of polyurethane foam material, and the thickness of the sound insulation layer is 1.0-2.0mm.

[0010] Furthermore, the moisture-proof base layer is made of high-density polyethylene material, and montmorillonite moisture-proof particles are evenly distributed inside the moisture-proof base layer, and the thickness of the moisture-proof base layer is 1.0-1.5mm.

[0011] In summary, this application includes the following beneficial technical effects: The application eliminates the use of adhesives and additives containing large amounts of volatile organic compounds (VOCs), reduces the release of pungent odors, effectively improves indoor air quality, reduces the risk of harm to the human respiratory tract and immune system, and provides users with a healthier living environment. In the formaldehyde-purifying functional layer of this application, the activated carbon fiber felt loaded with nano-titanium dioxide utilizes the adsorption properties of the activated carbon fiber felt and the photocatalytic activity of nano-titanium dioxide to adsorb and decompose free formaldehyde in the air; the chitin polymer film further enhances the formaldehyde-purifying effect through chemical reaction, continuously purifying indoor formaldehyde and reducing formaldehyde pollution. The wear-resistant surface layer of this application is made of polyvinyl chloride and nano silica composite material. Nano silica significantly improves the wear resistance of PVC material, enabling it to resist daily friction and scratches, and extend the service life of the flooring. In addition, the anti-slip microstructure design on the surface not only enhances the anti-slip performance, but also reduces the adhesion of dust and stains, making it easy to clean and maintain, and keeping the flooring clean. The sound insulation layer of this application uses polyurethane foam material. Its good elasticity can effectively absorb the impact of walking and provide a comfortable feel underfoot. At the same time, it can reduce noise interference to downstairs residents and has a certain heat insulation performance, which helps to maintain a stable indoor temperature and improve living comfort. The moisture-proof base layer of this application uses high-density polyethylene material and uniformly distributed montmorillonite moisture-proof particles. The strong water absorption of montmorillonite can effectively block the penetration of ground moisture, prevent the flooring from deforming and becoming moldy due to moisture, protect the upper structure, and enhance the durability and stability of the flooring in humid environments. The chitin polymer film in the formaldehyde-removing functional layer of this application has antibacterial properties, which can inhibit the growth of bacteria and mold on the surface of the floor covering, reduce odors caused by microbial reproduction and potential threats to human health, and create a more hygienic living space.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0017] Example: This application discloses a low-odor, formaldehyde-free, safe flooring material. Please refer to [link / reference]. Figures 1 to 3 It includes, from top to bottom, a wear-resistant surface layer 1, a formaldehyde-removing functional layer 2, a buffer and sound insulation layer 3, and a moisture-proof base layer 4. The adjacent layers of the wear-resistant surface layer 1, the formaldehyde-removing functional layer 2, the buffer and sound insulation layer 3, and the moisture-proof base layer 4 are bonded together with environmentally friendly adhesives.

[0018] The wear-resistant surface layer 1 is made of polyvinyl chloride and nano-silica composite material. The wear-resistant surface layer 1 has a thickness of 0.3-0.8mm and has an anti-slip microstructure on the surface. The addition of nano-silica significantly improves the wear resistance of PVC material, enabling it to effectively resist friction and scratches in daily use and extend the service life of the floor covering. At the same time, the surface of the wear-resistant surface layer 1 undergoes a special microstructural treatment, forming tiny concave and convex textures, which not only enhances the anti-slip performance but also reduces the adhesion of dust and stains, making it easy to clean and maintain.

[0019] The formaldehyde-removing functional layer 2 includes a core layer composed of activated carbon fiber felt 22 loaded with nano-titanium dioxide, and an upper chitosan polymer film 21 and a lower chitosan polymer film 23 located on the upper and lower sides of the activated carbon fiber felt 22 loaded with nano-titanium dioxide. The activated carbon fiber felt 22 loaded with nano-titanium dioxide has a thickness of 0.5-1.0 mm, and the upper chitosan polymer film 21 and the lower chitosan polymer film 23 each have a thickness of 0.1-0.3 mm. The nano-titanium dioxide in the activated carbon fiber felt 22 is loaded through adsorption and chemical bonding. The activated carbon fiber felt has a huge specific surface area and abundant microporous structure, which can efficiently adsorb harmful gases such as free formaldehyde in the air. Nano titanium dioxide has photocatalytic activity under ultraviolet light excitation, which can decompose organic pollutants such as formaldehyde adsorbed on the surface of activated carbon fiber felt into carbon dioxide and water, thus achieving continuous purification of formaldehyde. In addition, chitosan has good antibacterial properties, which can inhibit the growth of bacteria and mold on the surface of the floor covering. At the same time, the amino and other functional groups it contains can also react chemically with formaldehyde molecules, further enhancing the formaldehyde removal effect.

[0020] The sound insulation layer 3 is made of polyurethane foam and has a thickness of 1.0-2.0mm. The polyurethane foam has good elasticity and cushioning performance, which can effectively absorb the impact generated when walking, reduce noise interference to downstairs residents, and provide users with a more comfortable feel underfoot. In addition, the material also has a certain heat insulation performance, which helps to maintain the stability of indoor temperature.

[0021] The moisture-proof base layer 4 is made of high-density polyethylene material. Montmorillonite moisture-proof particles are evenly distributed inside the moisture-proof base layer 4, and the thickness of the moisture-proof base layer 4 is 1.0-1.5mm. Montmorillonite has extremely strong water absorption and moisture-proof properties, which can effectively absorb water vapor that seeps up from the ground, prevent water vapor from eroding the upper structure of the flooring, avoid problems such as deformation and mold of the flooring caused by dampness, and improve the durability and stability of the flooring.

[0022] The usage method of this embodiment is as follows: When installing the low-odor, formaldehyde-free, and safe flooring of this application, first ensure that the ground is flat, dry, and clean. Choose a suitable installation method according to the actual usage scenario, such as full adhesion, partial adhesion, or floating installation. For homes and other places with high stability requirements, full adhesion is recommended. Use a special environmentally friendly flooring adhesive to firmly adhere the flooring to the ground to ensure stability. During the adhesion process, be careful to lay the flooring flat to avoid air bubbles and wrinkles. For some temporary locations or areas with high installation convenience requirements, floating installation can be used, laying the flooring directly on the ground and utilizing its own weight and friction to maintain stability. After installation, wait for the adhesive to fully cure (if using the adhesive installation method), and it can be used normally.

[0023] During daily use, regular cleaning and maintenance of the floor covering is necessary. Use a mild detergent and a damp cloth to wipe it. Avoid using corrosive cleaners such as strong acids and alkalis to prevent damage to the surface of the floor covering. At the same time, maintaining good indoor ventilation is beneficial for the formaldehyde removal function of the floor covering and improves indoor air quality.

[0024] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
