Description

Technical Field

[0001] This utility model relates to the field of building decoration materials technology, specifically to fireproof and antibacterial PVC plastic flooring. Background Technology

[0002] In densely populated and environmentally demanding settings such as commercial offices, medical and health facilities, and schools, flooring materials must simultaneously meet multiple requirements, including fire safety, hygiene and antibacterial properties, durability and slip resistance, and environmental compatibility. According to data from the building materials industry, fire hazards from flooring materials in densely populated areas account for 28% of all fire hazards. In medical settings, approximately 30% of cross-infection incidents caused by bacterial growth on the floor are related to insufficient antibacterial properties of the flooring materials. PVC plastic flooring has become one of the mainstream flooring materials due to its convenient installation and comfortable feel. However, traditional products have significant shortcomings in the synergistic performance of fire resistance, antibacterial properties, and wear resistance, making it difficult to meet the needs of high-requirement scenarios.

[0003] However, most existing PVC plastic flooring adopts a "single-function superposition" design, such as only coating the surface with fire-retardant paint or antibacterial coating, failing to form an integrated composite structure. Fire-retardant paint is prone to wear and peeling, leading to a decrease in fire resistance. The antibacterial coating alone is difficult to penetrate into the flooring, only acting on the surface, and has compatibility issues with fire-retardant components. Furthermore, their addition can easily interfere with each other, resulting in neither function achieving the desired effect and failing to meet the dual rigid requirements of fire resistance and antibacterial properties in medical, school, and other scenarios. Therefore, we propose fire-retardant and antibacterial PVC plastic flooring. Utility Model Content

[0004] The purpose of this invention is to provide fire-resistant and antibacterial PVC plastic flooring to address the deficiencies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Fire-resistant and antibacterial PVC plastic flooring includes a back moisture-proof and sound-absorbing layer, a PVC support base layer on the upper surface of the back moisture-proof and sound-absorbing layer, a fire-resistant layer on the upper surface of the PVC support base layer, the fire-resistant layer being composed of a fire-resistant sub-layer and an antibacterial sub-layer, a surface wear-resistant and anti-slip layer on the upper surface of the fire-resistant layer, the surface wear-resistant and anti-slip layer including a PVC substrate layer fixedly installed on the surface of the fire-resistant layer and a nano-alumina wear-resistant layer installed on the surface of the PVC substrate layer, a surface antibacterial layer on the upper surface of the nano-alumina wear-resistant layer, and a glass fiber reinforced mesh inside the PVC support base layer.

[0006] Preferably, the back moisture-proof and sound-absorbing layer includes an EVA damping layer disposed on the bottom surface of the PVC support base layer, and a water-based polyurethane moisture-proof film is disposed on the bottom surface of the EVA damping layer.

[0007] Preferably, the bottom surface of the water-based polyurethane moisture-proof film is provided with anti-slip stripes, which are in the form of a grid.

[0008] Preferably, the thickness of the back moisture-proof and sound-absorbing layer is between 0.5mm and 0.8mm, and the thickness of the water-based polyurethane moisture-proof film is between 0.1mm and 0.2mm.

[0009] Preferably, the interior of the PVC support base layer also has multiple elastic rubber balls integrally formed, and the elastic rubber balls are solid structures.

[0010] Preferably, the glass fiber reinforced mesh has a mesh structure and the pore size of the glass fiber reinforced mesh is between 5mm and 8mm.

[0011] Preferably, the thickness of the fireproof layer is between 1.5mm and 2.0mm, and multiple anti-slip embossed groups are provided on the upper surface of the surface wear-resistant and anti-slip layer.

[0012] Preferably, the anti-slip embossed assembly includes an anti-slip pad and a plurality of anti-slip protrusions disposed around the anti-slip pad. The depth of the anti-slip embossed assembly is between 0.2mm and 0.3mm, and the spacing is between 2mm and 3mm.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model breaks through the design limitations of traditional PVC flooring by setting a fireproof layer composed of alternating fireproof and antibacterial sub-layers, combined with a nano-alumina wear-resistant layer and a surface antibacterial layer on the back of the moisture-proof and sound-absorbing layer. It achieves the synergistic effect of fireproof and antibacterial components, avoids mutual interference between functions, and at the same time provides antibacterial protection to the floor surface, thus achieving a combination of highly efficient fireproofing and antibacterial effects.

[0014] 2. This utility model, by setting a nano-alumina wear-resistant layer in the surface wear-resistant and anti-slip layer, and an anti-slip embossed group on the surface, the nano-alumina material greatly improves the surface hardness of the floor and effectively resists scratches and wear caused by daily friction. The anti-slip pads and anti-slip protrusions of the anti-slip embossed group further enhance the anti-slip properties of the ground.

[0015] 3. This utility model incorporates an EVA damping layer and a water-based polyurethane moisture-proof membrane on the back to create a moisture-proof and sound-absorbing layer. The EVA damping layer absorbs noise generated by ground vibrations and reduces sound transmission, while the water-based polyurethane moisture-proof membrane forms a highly efficient moisture barrier to prevent moisture from seeping into the floor and causing it to bulge. At the same time, the glass fiber reinforced mesh and elastic rubber balls in the PVC support base enhance the structural stability and foot feel of the floor. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0018] Please see Figures 1-3 This utility model provides a technical solution: fireproof and antibacterial PVC plastic flooring, including a back moisture-proof and sound-absorbing layer 1. A PVC support base layer 2 is formed on the upper surface of the back moisture-proof and sound-absorbing layer 1 by hot pressing. A fireproof layer 3 is provided on the upper surface of the PVC support base layer 2. The fireproof layer 3 is composed of a fireproof sub-layer 30 and an antibacterial sub-layer 31. Specifically, the antibacterial sub-layer 31 granular raw material is melted and mixed into the molten raw material of the fireproof sub-layer 30, and then injection molded. The fireproof sub-layer 30 improves the fireproof performance of the flooring and blocks the spread of flames. The antibacterial sub-layer 31 can inhibit the growth of bacteria. The interlaced structure allows the fireproof and antibacterial components to work synergistically, avoiding the problems of easy peeling and mutual interference of traditional single coatings, and realizing the stable performance of dual functions.

[0019] In this embodiment, a surface wear-resistant and anti-slip layer 4 is provided on the upper surface of the fireproof layer 3. The surface wear-resistant and anti-slip layer 4 includes a PVC substrate layer 40 fixedly installed on the surface of the fireproof layer 3 and a nano-alumina wear-resistant layer 41 integrally formed on the surface of the PVC substrate layer 40. The nano-alumina material has high hardness and strong wear resistance, which can resist scratches and wear caused by daily friction, extend the service life of the floor surface, and avoid the problem of easy wear of the surface of traditional PVC flooring leading to a decrease in aesthetics and exposure of the internal structure. Specifically, an antibacterial layer 43 is provided on the upper surface of the nano-alumina wear-resistant layer 41 to achieve full coverage antibacterial protection on the floor surface. The antibacterial layer 43 can be made of chitosan-modified cellulose acetate film material, which is odorless and non-corrosive. At the same time, the chitosan-modified cellulose acetate film material does not release toxic gases when burned, thus achieving an antibacterial effect.

[0020] Furthermore, the back moisture-proof and sound-absorbing layer 1 includes an EVA damping layer 11 set on the bottom surface of the PVC support base layer 2. A water-based polyurethane moisture-proof membrane 10 is set on the bottom surface of the EVA damping layer 11. The EVA damping layer 11 can absorb the noise generated by ground vibration and reduce sound transmission. The water-based polyurethane moisture-proof membrane 10 can prevent moisture from penetrating into the floor and prevent the floor from bulging and deforming due to long-term exposure to a humid environment. This allows the floor to have both moisture-proof and sound-absorbing functions, making it suitable for humid and noise-sensitive environments.

[0021] In addition, the bottom surface of the water-based polyurethane moisture-proof membrane 10 is provided with anti-slip stripes 101. The anti-slip stripes 101 are grid-like, which increases the friction between the back of the floor and the ground substrate, prevents the floor from shifting or sliding after installation or during use, ensures the stability of the floor after installation, reduces problems such as the expansion of splicing gaps caused by floor displacement, and improves installation stability.

[0022] It is worth noting that the thickness of the back moisture-proof and sound-absorbing layer 1 is between 0.5mm and 0.8mm. This ensures that the EVA damping layer 11 has sufficient thickness to absorb ground vibrations and achieve effective sound absorption, while avoiding problems such as warping or incompatibility with other decoration materials after the floor is installed due to excessive thickness. This balances the sound absorption effect with the installation compatibility, ensuring that the floor can be installed stably in different scenarios. The thickness of the water-based polyurethane moisture-proof membrane 10 is between 0.1mm and 0.2mm. This not only forms a complete moisture barrier to effectively prevent moisture from penetrating into the floor and prevent the floor from bulging or deforming due to moisture, but also avoids increasing the overall weight and cost of the floor due to excessive thickness. At the same time, the thin design can fit the surface of the EVA damping layer 11 without affecting the overall structural stability of the back moisture-proof and sound-absorbing layer 1, achieving a balance between efficient moisture protection and lightweight design.

[0023] like Figure 1 As shown, the PVC support base layer 2 has a glass fiber reinforced mesh 20 inside. The glass fiber reinforced mesh 20 has a mesh structure and the pore size of the glass fiber reinforced mesh 20 is between 5mm and 8mm. The PVC support base layer 2 also has multiple elastic rubber balls 21 integrally formed inside. The elastic rubber balls 21 have a solid structure, which enhances the structural strength of the PVC support base layer 2 and prevents the floor from breaking or deforming when subjected to external impact. The elastic rubber balls 21 also improve the elasticity of the floor underfoot, making it more comfortable for people to walk on, thus balancing the durability of the floor and the user experience.

[0024] In addition, the thickness of the fireproof layer 3 is between 1.5mm and 2.0mm. The upper surface of the wear-resistant and anti-slip layer 4 is provided with multiple anti-slip embossed groups 42. The anti-slip embossed groups 42 include anti-slip pads 421 and multiple anti-slip protrusions 422 arranged around the anti-slip pads 421. The depth of the anti-slip embossed groups 42 is between 0.2mm and 0.3mm, and the spacing is between 2mm and 3mm. This increases the friction between the floor surface and the sole of the shoe, which can effectively prevent people from slipping, especially in wet environments, and improve the safety of use.

[0025] It is worth noting that the PVC substrate layer 40 can be injection molded using SG-5 type PVC resin; the nano-alumina wear-resistant layer 41 is hot-pressed onto the upper surface of the PVC substrate layer 40. The nano-alumina particles, with a particle size of 50-100nm, are uniformly dispersed in the acrylic resin matrix to form the nano-alumina wear-resistant layer 41, thereby improving its wear resistance; the fireproof sublayer 30 can be made using SG-3 type PVC resin as the matrix, with modified magnesium hydroxide mixed internally, and coated with a silane coupling agent KH-550 and an expansion system of ammonium polyphosphate-pentaerythritol-melamine to give it a fireproof protection effect; the antibacterial sublayer 31 can be made by mixing silver-loaded zirconium phosphate and zinc oxide nanoparticles to improve the overall fireproof and antibacterial properties.

[0026] When using the fireproof and antibacterial PVC plastic flooring of this utility model, the water-based polyurethane moisture-proof film 10 on the back of the flooring is placed downwards and aligned with the ground baseline. The anti-slip stripes 101 increase the friction between the flooring and the ground. The flooring is spliced ​​piece by piece, and the structural strength of the PVC support base layer 2 is used to maintain the flatness of the installation and avoid the flooring from breaking due to external forces. After installation, check that there are no obvious gaps at the joints of the flooring. Press the PVC support base layer 2 to feel the foot feedback of the elastic rubber ball 21. Test the smoothness of the surface antibacterial layer 43. At the same time, verify the anti-slip effect of the anti-slip embossed group 42 to ensure that the whole meets the usage requirements. The fireproof layer 3 can provide fire protection, and the antibacterial sub-layer 31 and the surface antibacterial layer 43 can inhibit bacterial growth.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
