Technical Field
[0001] This utility model relates to the field of flooring technology, specifically to a noise-reducing composite floor. Background Art
[0002] As a flooring material used over large areas, flooring performance has a crucial impact on the comfort of living and working environments. Traditional flooring often focuses on one or a few performance aspects; for example, some flooring prioritizes aesthetics and wear resistance while neglecting sound insulation and noise reduction. In multi-story buildings or densely populated areas, noise transmitted through the flooring can cause serious disturbances, affecting people's rest, work efficiency, and quality of life. Furthermore, poor waterproofing can lead to problems such as moisture damage, warping, and mold growth, reducing the flooring's lifespan and safety. Summary of the Invention
[0003] (a) Technical problems to be solved
[0004] The technical problem to be solved by this utility model is that the existing flooring has poor noise reduction capabilities, which causes noise to spread through the base plate.
[0005] (2) Technical solution
[0006] To solve the above problems, this utility model provides the following technical solution:
[0007] A noise-reducing composite floor includes a composite floor body, the composite floor body comprising a surface layer, a first waterproof layer, a first noise-reducing layer, a first reinforcing layer, a second noise-reducing layer, a second reinforcing layer, a second waterproof layer, and a bottom layer;
[0008] The first waterproof layer is disposed between the top layer and the first noise reduction layer; the first reinforcement layer is disposed between the first noise reduction layer and the second noise reduction layer; the second reinforcement layer is disposed between the second noise reduction layer and the second waterproof layer; and the bottom layer is disposed on the lower end face of the second waterproof layer.
[0009] The noise reduction layer 1 includes a cork frame 1 and a noise reduction sheet 1. The cork frame 1 is provided with a plurality of rectangular grooves 1 for mounting the noise reduction sheet 1.

[0017] Furthermore, the bottom layer is made of thermoplastic polyester elastomer material.
[0018] (3) Beneficial effects
[0019] The beneficial effects of this utility model are:
[0020] 1. The cork frame of noise reduction layer one uses its porosity to initially absorb sound, while the noise reduction sheet inside the rectangular groove one further absorbs sound waves. The same applies to noise reduction layer two, but the openings of the rectangular groove two are opposite to those of the rectangular groove one, allowing sound waves to be reflected, refracted, and absorbed multiple times between the two layers, effectively blocking noise of different frequencies. It is widely applicable in residential and office spaces.
[0021] 2. Waterproof layer one is located below the surface layer, and waterproof layer two is located below the reinforcement layer two.

Therefore, they should not be construed as limitations on this utility model.
[0033] Please see Figure 1-4 The following is a noise-reducing composite floor, the composite floor body 1 comprising a surface layer 101, a waterproof layer 102, a noise-reducing layer 103, a reinforcing layer 104, a noise-reducing layer 105, a reinforcing layer 106, a waterproof layer 107, and a bottom layer 108.
[0034] The first waterproof layer 102 is disposed between the first surface layer 101 and the first noise reduction layer 103, the first reinforcement layer 104 is disposed between the first noise reduction layer 103 and the second noise reduction layer 105, the second reinforcement layer 106 is disposed between the second noise reduction layer 105 and the second waterproof layer 107, and the bottom layer 108 is disposed on the lower end face of the second waterproof layer 107.
[0035] The top layer, Surface 101, is the outermost layer of the flooring and is in direct contact with the outside environment. It is made of stone-plastic composite material. Stone-plastic composite material is a new type of environmentally friendly composite material with excellent wear resistance. It can withstand the friction generated by daily walking and furniture movement, and maintains its surface smoothness and flatness even after long-term use. At the same time, its good decorative properties can meet the needs of different decoration styles. The rich selection of colors and textures can match the overall interior decoration, creating a beautiful and elegant spatial atmosphere. In addition, stone-plastic composite material also has strong stain resistance; stains do not easily penetrate, making daily cleaning and maintenance convenient and effectively reducing cleaning costs and labor intensity.
[0036] Waterproof layer 102 is located below surface layer 101 and is applied to the lower surface of surface layer 101 using polyurethane waterproof coating. This polyurethane waterproof coating has excellent waterproof performance, forming a continuous, dense waterproof membrane that effectively prevents moisture from penetrating downwards from the floor surface. Whether it's spilled water during daily cleaning or accidental water immersion, waterproof layer 102 provides a reliable barrier, protecting the internal structure of the floor from moisture erosion, thereby extending the floor's lifespan and ensuring stable performance even in humid environments.
[0037] The noise reduction layer 103 is positioned below the waterproof layer 102 and consists of a cork frame 103a and a noise reduction sheet 103b. The cork frame 103a is made of cork, a natural porous material with excellent sound absorption properties. Its internal micropores allow sound waves to undergo multiple reflections and scatterings as they propagate, converting sound energy into heat and other forms of energy, thus achieving initial noise reduction. The cork frame 103a has multiple evenly distributed rectangular grooves 103c, providing installation space for the noise reduction sheet 103b. The noise reduction sheet 103b is made of polyurethane foam board, a highly efficient sound-absorbing material whose porous structure effectively absorbs sound waves, further reducing noise propagation. When the sound waves reach the noise reduction layer 103, they first undergo preliminary sound absorption treatment through the cork frame 103a, and then enter the noise reduction sheet 103b in the rectangular groove 103c, where they are deeply absorbed by the polyurethane foam board, thereby significantly reducing the transmission of noise to the lower floor.
[0038] The first reinforcement layer 104 is located between the first noise reduction layer 103 and the second noise reduction layer 105, and is made of medium-density fiberboard (MDF). MDF has high strength and stability; its uniform fiber structure evenly distributes the pressure on the floor, preventing excessive localized stress that could lead to deformation. Under the influence of the first reinforcement layer 104, the floor can withstand significant weight, such as the pressure of furniture or concentrated activity, while maintaining structural integrity and preventing dents, bends, or other deformations, providing a solid foundation for the long-term use of the floor.
[0039] Noise reduction layer 2 (105) is installed below reinforcement layer 1 (104) and is also composed of cork frame 2 (105a) and noise reduction sheet 2 (105b). Cork frame 2 (105a) is made of the same material as cork frame 1 (103a), both being cork and possessing similar sound absorption properties. Cork frame 2 (105a) has multiple rectangular grooves 2 (105c), with the openings of the rectangular grooves 2 (105c) facing downwards, opposite to the opening direction of the rectangular grooves 1 (103c). This unique design causes a difference in the propagation path of sound waves when passing through noise reduction layer 2 (105) compared to when passing through noise reduction layer 1 (103). The sound waves are repeatedly reflected, refracted, and absorbed between the two noise reduction layers, greatly improving the noise reduction effect. Noise reduction sheet 2 (105b) is also made of polyurethane foam board and works together with noise reduction sheet 1 (103b) to comprehensively absorb and block sound waves of different frequencies, effectively reducing the overall noise transmission of the floor and creating a quiet environment indoors.
[0040] Reinforced layer 2 (106) is positioned below noise-reducing layer 2 (105) and is also made of medium-density fiberboard (MDF). Reinforced layer 2 (106) further enhances the strength and stability of the flooring, working in conjunction with reinforced layer 1 (104) to form a double-layer reinforced structure. This design better withstands complex usage environments and significant external forces. Reinforced layer 2 (106) works in conjunction with reinforced layer 1 (104) to evenly distribute impact forces, preventing damage to the flooring structure and ensuring the floor remains flat and stable throughout long-term use.
[0041] Waterproof layer 2 (107) is located below reinforced layer 2 (106) and is applied to the lower surface of reinforced layer 2 (106) using polyurethane waterproof coating. Waterproof layer 2 (107) and waterproof layer 1 (102) together form the floor's waterproof system, providing waterproof protection to the floor's internal structure from both top and bottom. Even if the bottom of the floor may come into contact with a damp surface or a small amount of water, waterproof layer 2 (107) can effectively prevent moisture from penetrating upwards, ensuring the floor's interior remains dry and preventing problems such as deformation, mold, and rot caused by moisture, further improving the floor's durability and reliability.
[0042] The bottom layer 108, as the lowest layer of the composite flooring body 1, is made of thermoplastic polyester elastomer material. Thermoplastic polyester elastomer material has excellent flexibility, allowing it to deform to a certain extent when the flooring is subjected to external pressure or impact, thereby absorbing and buffering the impact force and reducing damage to the upper structure of the flooring and to users. Furthermore, the bottom layer 108 also helps reduce noise transmission to some extent; its flexible structure can further block and attenuate sound waves, forming a comprehensive noise reduction system together with noise reduction layer one 103 and noise reduction layer two 105.
[0043] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
