Description

Technical Field

[0001] This utility model belongs to the field of wood flooring technology, specifically relating to a composite antibacterial wood flooring. Background Technology

[0002] As people's living standards improve and their health awareness increases, the requirements for indoor environmental quality are becoming increasingly stringent. As an important component of interior decoration, flooring has received more and more attention for its performance.

[0003] Wood flooring is mainly divided into six categories: solid wood flooring, engineered wood flooring, multi-layer composite flooring, bamboo flooring, and cork flooring. Ordinary wood flooring is prone to warping, cracking, or mold growth due to long-term use, temperature fluctuations, or moisture. To minimize problems after installation, engineered wood flooring, multi-layer composite flooring, and other types that can withstand various complex environments have a higher market share. Composite wood flooring, made by cross-laminating different tree species, overcomes the unidirectional isotropic nature of solid wood flooring, resulting in low shrinkage and expansion rates, good dimensional stability, and retaining the natural wood grain and comfortable feel of solid wood. Suitable for consumers who appreciate the natural beauty of solid wood flooring but are concerned about its instability, composite wood flooring combines the stability of engineered wood flooring with the aesthetics of composite wood flooring, while also offering environmental advantages. This high-performance composite flooring represents a significant trend in the wood flooring industry.

[0004] While traditional wood flooring boasts advantages such as natural beauty and comfortable feel underfoot, it still has several drawbacks. In terms of antibacterial properties, traditional wood flooring is prone to the growth of bacteria, mold, and other microorganisms, especially in humid environments. Common bacteria such as E. coli and Staphylococcus aureus can proliferate rapidly, not only producing unpleasant odors but also potentially harming human health. Utility Model Content

[0005] The purpose of this invention is to provide a composite antibacterial wood flooring to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a composite antibacterial wood flooring, comprising an antibacterial wood-plastic substrate, a buffer and noise reduction layer, a reinforcement layer, a flame-retardant layer, a wear-resistant layer, and a balancing layer. The buffer and noise reduction layer is bonded to the lower surface of the antibacterial wood-plastic substrate with polyurethane adhesive. The reinforcement layer is bonded to the upper surface of the antibacterial wood-plastic substrate with an impregnation liquid. The flame-retardant layer is bonded to the upper surface of the reinforcement layer with a coupling agent. The wear-resistant layer is bonded to the upper surface of the flame-retardant layer with resin. The balancing layer is bonded to the lower surface of the buffer and noise reduction layer with resin.

[0007] In a preferred embodiment, the buffer noise reduction layer includes two rubber sheets and an EVA foam material layer bonded between the two rubber sheets.

[0008] In a preferred embodiment, the reinforcing layer is an antibacterial impregnated carbon fiber cloth.

[0009] In a preferred embodiment, the flame-retardant layer is an inorganic flame-retardant board.

[0010] In a preferred embodiment, the wear-resistant layer is antibacterial impregnated wear-resistant paper.

[0011] In a preferred embodiment, the balancing layer is an antibacterial impregnated balancing paper.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This composite antibacterial wood flooring uses antibacterial wood-plastic composite material as the base layer, giving the flooring excellent waterproof and moisture-proof performance. It can effectively prevent moisture from penetrating into the flooring, solving the problem of traditional wood flooring being sensitive to water and moisture. When preparing the antibacterial wood-plastic composite material as the antibacterial wood-plastic composite base layer, plastic antibacterial agents are added, and natural bamboo fiber powder with antibacterial properties is selected to give it antibacterial properties and reduce the growth of bacteria. This composite antibacterial wood flooring, through the setting of a cushioning and noise reduction layer, with rubber sheet and EVA foam material layer having good elasticity and cushioning performance, can reduce the noise generated when walking and improve the comfort of the feet; This composite antibacterial wood flooring, through the addition of a reinforcing layer, utilizes carbon fiber cloth, which possesses high strength and high modulus, significantly improving the overall strength, rigidity, and impact resistance of the flooring. This reduces deformation and damage during use. Furthermore, the carbon fiber cloth is impregnated in an antibacterial agent solution, giving it antibacterial properties. The flame-retardant layer, made from inorganic flame-retardant materials such as aluminum hydroxide or magnesium oxide with added flame retardants, decomposes and absorbs heat at high temperatures, releasing water of crystallization, lowering the material's surface temperature, inhibiting the combustion of combustibles, and thus providing flame retardancy and enhancing the flooring's fire safety performance. Additionally, a small amount of antibacterial agent is added to the flame-retardant layer material to further enhance its antibacterial properties. Attached Figure Description

[0024] The working principle and usage process of this utility model are as follows: First, by using antibacterial wood-plastic composite material as the substrate layer of the floor, the floor has excellent waterproof and moisture-proof performance, effectively preventing moisture from penetrating into the floor's interior, thus solving the problem of traditional wood flooring's sensitivity to water and moisture. When preparing the antibacterial wood-plastic composite material as the antibacterial substrate 1, a plastic antibacterial agent is added, and natural bamboo fiber powder with antibacterial properties is selected to give it antibacterial properties. Through the setting of the buffer and noise reduction layer 2, the rubber sheet 21 and the EVA foam material layer 22 have good elasticity and cushioning performance, which can reduce noise generated during walking and improve foot comfort. Through the setting of the reinforcing layer 3, the carbon fiber cloth has high strength and high modulus characteristics, which can significantly improve the overall strength, rigidity, and impact resistance of the floor, reducing deformation and damage during use. Moreover, the carbon fiber cloth, in addition to... Impregnation with an antibacterial agent imparts antibacterial properties to the carbon fiber cloth. The flame-retardant layer 4, made of inorganic flame-retardant materials such as aluminum hydroxide or magnesium oxide with added flame retardants, decomposes and absorbs heat at high temperatures, releasing water of crystallization, lowering the material's surface temperature, inhibiting the combustion of combustibles, and thus providing flame retardancy and improving the floor's fire safety performance. Furthermore, the addition of a small amount of antibacterial agent to the flame-retardant layer 4 enhances its antibacterial properties. The wear-resistant layer 5, impregnated with a composite antibacterial adhesive, not only provides antibacterial properties but also excellent wear resistance, resisting friction and scratches during daily use and protecting the floor's internal structure.
