Abstract
Description
Technical Field
[0001] This utility model relates to the field of engineered wood flooring technology, specifically a low-noise engineered wood flooring. Background Technology
[0002] As an important part of interior decoration, flooring not only needs to possess basic characteristics such as aesthetics and durability, but also should excel in functional aspects such as noise reduction and moisture resistance. Traditional solid wood or composite flooring often falls short in sound absorption and noise reduction, making it difficult to meet the needs of modern consumers. For example, ordinary flooring is prone to generating significant noise during daily walking and furniture movement, and it is also susceptible to deformation and damage after being exposed to moisture, affecting its lifespan and the comfort of the indoor environment. Summary of the Invention
[0003] (a) Technical problems to be solved
[0004] The technical problem this invention aims to solve is that traditional engineered wood flooring is prone to generating noise during daily use.
[0005] (II) Technical Solution
[0006] To solve the above problems, this utility model provides the following technical solution:
[0007] A low-noise solid wood composite flooring comprises, from top to bottom, an alumina wear-resistant layer, a middle layer, a natural wood veneer layer, a silicone layer, an upper wood core board layer, an aluminum frame layer, a lower wood core board layer, a moisture-proof bottom layer, and a moisture-proof coating.
[0008] The alumina wear-resistant layer is applied to the upper surface of the intermediate layer by a spraying process. The intermediate layer is made of bamboo fiberboard, and the natural wood veneer layer has micropores. The silicone layer is made of hollow elastic silicone, and the interior of the elastic silicone is filled with a non-Newtonian fluid.
[0009] Both the upper and lower wood core layers are made of solid wood substrates pressed together from multiple layers of wood boards. The aluminum frame layer is made of aluminum alloy and has multiple honeycomb-shaped grooves filled with plant-based porous sound-absorbing gel. The moisture-proof bottom layer is made of high-density fiberboard, and the moisture-proof coating is a microencapsulated self-healing coating applied to the lower surface of the moisture-proof bottom layer using a spraying process.
[0010] Furthermore, the thickness of the alumina wear-resistant layer is not less than 0.2 mm.
[0011] Furthermore, the thickness of the natural wood veneer layer is not less than 0.5 mm.
[0012] Furthermore, the micropores on the natural wood veneer layer are multiple and evenly distributed on the natural wood veneer layer, and the micropores penetrate the natural wood veneer layer.
[0013] Furthermore, the honeycomb-shaped grooves of the aluminum frame layer are provided in a plurality of uniformly arranged on the aluminum frame layer, and each groove is filled with plant-based porous sound-absorbing gel.
[0014] (III) Beneficial Effects
[0015] The beneficial effects of this utility model are:
[0016] 1. In this solution, the alumina wear-resistant layer, with its relatively high density, initially blocks sound from penetrating downwards, altering the sound wave propagation path and causing some sound energy to be reflected back. The middle layer uses bamboo fiberboard, which has a lower density than the alumina wear-resistant layer. When sound passes through the interface between the two layers, the sound energy is scattered and reflected due to the difference in medium density, effectively slowing down the speed and intensity of noise propagation. The micron-sized pores evenly distributed on the natural wood veneer layer cause sound waves to be reflected and refracted multiple times within the pores, continuously consuming sound energy and further weakening noise. The honeycomb-shaped grooves in the aluminum frame layer are filled with plant-based porous sound-absorbing gel. After noise waves enter the grooves, they are absorbed and converted by the porous sound-absorbing gel, minimizing the amount of noise propagating from the floor into the space below, creating a quiet atmosphere indoors.
[0017] 2. The silicone layer uses hollow elastic silicone filled with a non-Newtonian fluid. During everyday walking, moving furniture, or even dropping heavy objects, the impact force acts on the floor. The non-Newtonian fluid quickly hardens, working in conjunction with the elastic silicone to create a cushioning effect, preventing the floor from generating high-decibel noise due to violent vibrations. This effectively suppresses noise at the source, greatly improving the floor's sound insulation.
[0018] 3. The alumina wear-resistant layer is tightly adhered to the upper surface of the intermediate layer through a spraying process, providing a solid protective barrier for the floor. In everyday use scenarios such as homes and offices, frequent foot traffic and furniture dragging can cause wear and tear on the floor surface. Attached image description:

Detailed Implementation
[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0023] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0024] Please see Figures 1-2 The example shown is a low-noise solid wood composite floor, which, from top to bottom, consists of an aluminum oxide wear-resistant layer 1, a middle layer 2, a natural wood veneer layer 3, a silicone layer 4, an upper wood core board layer 5, an aluminum frame layer 6, a lower wood core board layer 7, a moisture-proof bottom layer 8, and a moisture-proof coating 9.
[0025] The alumina wear-resistant layer 1 is applied to the upper surface of the intermediate layer 2 via a spraying process. Its thickness is no less than 0.2 mm, providing excellent wear resistance and preventing frequent friction wear. This ensures the surface flatness of the floor after long-term use and reduces additional noise caused by surface wear. In addition to its wear resistance, the relatively high density of the alumina wear-resistant layer 1 can also block sound from penetrating downwards, providing initial noise reduction.
[0026] The middle layer 2 is made of bamboo fiberboard. Bamboo fiber itself has good strength and toughness, and its density is slightly lower than that of the alumina wear layer 1. This decreasing density design means that when sound encounters different medium interfaces during transmission, some of the sound energy is reflected and scattered due to the differences in medium properties, and cannot propagate in a straight line. This effectively slows down the speed and intensity of noise transmission downwards, reducing the possibility of noise penetrating the floor.
[0027] The natural wood veneer layer 3 has micropores 10 with a thickness of not less than 0.5 mm. Multiple micropores 10 are evenly distributed on the natural wood veneer layer 3 and penetrate the entire layer. The micropores 10 are micron-sized pores formed by laser engraving. The density of the natural wood veneer layer 3 is lower than that of the intermediate layer 2. When sound waves are transmitted, the structure of the micropores 10 causes the sound waves to be reflected and refracted multiple times, continuously dispersing and dissipating the sound energy, further weakening the noise intensity.
[0028] The silicone layer 4 is made of hollow elastic silicone, and a non-Newtonian fluid 11 is filled inside the elastic silicone. When subjected to external impact, such as a heavy object falling or being stepped on, the non-Newtonian fluid quickly changes its state and hardens, working in conjunction with the elastic silicone to buffer the impact force and prevent the floor from generating high-decibel noise due to violent vibration, thus reducing the amount of noise generated at the source.
[0029] Both the upper wood core layer 5 and the lower wood core layer 7 are made of solid wood substrates pressed together with multiple layers of wood boards. The multi-layer solid wood substrate structure is stable and provides solid support for the entire floor.
[0030] The aluminum frame layer 6 is made of aluminum alloy and has multiple honeycomb-shaped grooves 12, each filled with plant-based porous sound-absorbing gel. The aluminum alloy frame layer is not only lightweight and strong, but its honeycomb structure combined with the sound-absorbing gel forms a highly efficient sound-absorbing system that can capture, absorb, and convert residual noise passing through the upper structure, greatly reducing the amount of noise transmitted from the floor to the space below.
[0031] The moisture-proof base layer 8 is made of high-density fiberboard, effectively blocking the upward penetration of ground moisture, preventing the floor from warping due to moisture, and ensuring the stability of the physical properties of each functional layer. This prevents the noise reduction and wear resistance functions from deteriorating due to moisture. The moisture-proof coating 9 uses a microencapsulated self-healing coating applied to the lower surface of the moisture-proof base layer 8 via a spraying process. When minor damage occurs to the moisture-proof coating, the microcapsules rupture and automatically repair the damaged area, continuously maintaining excellent moisture-proof performance.
[0032] The embodiments are detailed, and 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 exemplary and non-limiting in all respects, and the scope of the present invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
