Description

Technical Field

[0001] This application relates to the field of flooring technology, and more specifically, to a reinforced soundproof floor. Background Technology

[0002] Currently, noise reduction technologies for floors on the market are mainly achieved through the following methods:

[0003] Adding a sound-absorbing pad at the bottom: This buffers impact sound by attaching low-density materials such as cork and foam to the bottom of the floor, but it increases the thickness of the floor and is prone to aging and deformation with long-term use.

[0004] Substrate structure improvement: Some composite flooring designs through holes, honeycomb structures or embedded elastic layers in the substrate layer, but such technologies are mostly for flexible stone-plastic substrates and cannot be adapted to the high-density wood fiber substrates of engineered wood flooring. In addition, the process is complicated and the cost is high.

[0005] There is an urgent need for those skilled in the art to provide a noise reduction technology that is adapted to the characteristics of engineered wood flooring, and to break through the noise reduction bottleneck while ensuring mechanical performance. Utility Model Content

[0029] Please refer to Figure 1 This embodiment provides a reinforced soundproof floor 100, which includes a soundproof reinforcement layer 110, a soundproof foam layer 120, a balancing layer 130, and a cork layer 140 stacked along a preset direction.

[0030] Please refer to Figure 1 The working principle of this reinforced soundproof floor 100 is as follows:

[0031] The reinforced soundproof flooring 100 includes a soundproofing reinforcement layer 110, a soundproofing foam layer 120, a balancing layer 130, and a cork layer 140 stacked along a predetermined direction. Through its multi-layered structural design and material optimization, the reinforced soundproof flooring 100 significantly improves sound insulation, mechanical properties, and foot comfort, while maintaining its environmentally friendly characteristics.

[0032] Further, please refer to Figure 1 In this embodiment, when configuring the sound-absorbing reinforcement layer 110, the sound-absorbing reinforcement layer 110 includes a wear-resistant layer 111, a patterned paper layer 112, and a stone-plastic composite layer 113 arranged sequentially along a preset direction.

[0033] The wear-resistant layer 111 is made of aluminum oxide, and its surface hardness is not less than 4H. The sound-absorbing reinforcement layer 110 may also include a PU adhesive paper layer 114, which is located between the patterned paper layer 112 and the stone-plastic composite layer 113.

[0034] When configuring the sound-absorbing foam layer 120, the sound-absorbing foam layer 120 is a foam layer made of IXPP or IXPE material. Furthermore, the thickness of the sound-absorbing foam layer 120 can be 1-3 mm, and its porosity can be 60%-80%.

[0035] When configuring the balancing layer 130, the balancing layer 130 includes a high-density substrate layer 131 and a balancing paper layer 132, with the balancing paper layer 132 covering the side of the high-density substrate layer 131 facing the sound-absorbing foam layer 120 or the cork layer 140. In this embodiment, the high-density substrate layer 131 is covered with the balancing paper layer 132 on both sides facing the sound-absorbing foam layer 120 and the cork layer 140.

[0036] Based on the above structure, to improve the stability of the connection and extend its service life, the high-density substrate layer 131 is provided with multiple first positioning portions on the side facing the sound-absorbing foam layer 120; the multiple first positioning portions are arc-shaped protrusions or arc-shaped grooves spaced apart along the extension direction of the balance layer 130. In addition, the high-density substrate layer 131 is provided with multiple second positioning portions on the side facing the cork layer 140; the multiple second positioning portions are arc-shaped protrusions or arc-shaped grooves spaced apart along the extension direction of the balance layer 130. In this way, it can work together with the aforementioned balance paper layer 132 to improve its stability and prevent warping, and it can also prevent displacement during pressing and use, which could lead to pressing errors and reduced quality.

[0037] Based on the above, please refer to Figure 1 The structure of the reinforced soundproof floor 100 is as follows:

[0038] The layers arranged from top to bottom are: wear-resistant layer 111, patterned paper layer 112, PU adhesive paper layer 114, stone-plastic composite layer 113 (SPC), sound-absorbing foam layer 120, balancing paper layer 132, high-density substrate layer 131 (HDF), balancing paper layer 132, and cork layer 140. Moreover, during the manufacturing process, the above structures can be stacked in sequence and formed into an integral structure through a high-temperature pressing process.

[0039] The wear-resistant layer 111, the patterned paper layer 112, the PU adhesive paper layer 114, and the stone-plastic composite layer 113 (SPC) combine to form the sound-absorbing reinforcement layer 110. The wear-resistant layer 111 uses alumina (Al2O3) wear-resistant material with a surface hardness of not less than 4H. The patterned paper layer 112 provides a decorative effect, simulating the texture of real wood. The PU adhesive paper layer 114 forms high bonding strength during high-temperature pressing, preventing delamination. The stone-plastic composite layer 113 (SPC) has high rigidity and impact resistance, enhancing the surface's resistance to deformation.

[0040] The silencing foam layer 120 is made of IXPP or IXPE material, which has the characteristics of moisture resistance and creep resistance. It has a thickness of 1-3 mm and a porosity of 60%-80%, and is used to absorb the vibration energy of stepping and block the transmission of sound waves.

[0041] In addition, the balancing paper layer 132, the high-density substrate layer 131 (HDF), and the balancing paper layer 132 are arranged from top to bottom to form a balancing layer 130; while the high-density substrate layer 131 (HDF) provides load-bearing capacity and avoids warping caused by unilateral stress; the balancing paper layer 132 is symmetrically covered on both sides of the HDF to form a double balancing paper structure to compensate for the rigidity defects of the HDF.

[0042] The cork layer 140 can be made of natural cork material that has been treated with moisture resistance to further absorb residual vibrations while retaining the environmentally friendly properties of natural materials.

[0043] Based on the above structural design, the IXPP / IXPE sound-absorbing foam layer 120 absorbs the vibration energy from footsteps, blocks the downward transmission of sound waves, and significantly reduces noise. The SPC stone-plastic composite layer 113 and the HDF high-density substrate layer 131 work together to provide high rigidity and load-bearing capacity, ensuring that the floor is not easily deformed. The synergistic effect of the IXPP / IXPE foam layer and the cork layer 140 provides a good foot feel. The cork layer 140 is a natural material, pollution-free, and meets environmental protection requirements. Furthermore, the PU adhesive paper layer 114 forms high bonding strength during high-temperature pressing, preventing delamination and extending the service life of the floor.

[0044] It should be noted that in this embodiment, IXPP is cross-linked polypropylene, a highly elastic and moisture-resistant foam material; IXPE is cross-linked polyethylene, a highly elastic and creep-resistant foam material; HDF is high-density fiberboard, a high-density substrate made of wood fibers; DHF is dense hard fiberboard, a rigider high-density substrate; PU is polyurethane, a high-strength adhesive material; and SPC is stone plastic composite, a high-rigidity material composed of stone powder and plastic.

[0045] This engineered wood flooring, known as the 100, is suitable for homes, commercial spaces, and other environments, especially those requiring high noise reduction and environmental friendliness, such as bedrooms, offices, and libraries. Through its multi-layered structural design and optimized materials, the 100 boasts superior noise reduction, excellent mechanical properties, comfortable feel, and environmental friendliness. This makes it quieter than traditional engineered wood flooring while maintaining excellent mechanical properties and comfort, giving it broad application prospects and market value.

[0046] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
