Abstract

This design discloses a multilayer soundproof & anti-vibration composite flooring. Density difference was used to buffer the pressure of the floor, as results, a Soundproof & Anti-vibration effect can be achieved. The characteristic of composite flooring contains the floor surface and different density of underlayers. Wherein the underlayers could be staggered, thereby forming a multilayer composite flooring when combined with the floor surface.

Description

Multi-layer soundproof shock absorbing composite floor

Sound-absorbing and shockproof floor technology

Most of the existing floors are made of a single material, and the biggest disadvantage is that the problem of sound insulation and shock absorption cannot be solved. Foam materials with low density must be used to solve the shock absorption problem. However, due to the relatively high compression ratio of the low-density foamed material, it is easy to cause uneven thickness and dent problems, which in turn affects product use. This creation uses a different density of staggered design to allow the product to improve sound insulation while also providing shock absorption, which is not possible with a single structure or material.

The present invention overcomes the deficiencies of the prior art, and discloses a multi-layered sound-absorbing and shock absorbing composite floor, which is characterized by comprising a floor surface layer and two or more intermediate layers and bottom layers of different densities. The middle layer and the bottom layer can be arranged in a staggered manner, and then the multi-layer structure is formed with the floor surface layer. The present invention can be realized by adopting the following technical solutions:

1. A sound-absorbing and shock-absorbing composite floor comprising at least a floor covering layer and an intermediate layer for improving sound insulation and shock absorption of the floor, two or more different densities.

2. The intermediate layer is made of at least a rubber material and a recycled polyurethane, wherein the rubber material may be selected from general rubber, plastic, foamed rubber and recycled rubber or plastic, and the polyurethane may be selected from hard foam polyurethane and soft foam polyurethane;

3. The density of the first intermediate layer ranges from 200 to 900 KG/m3, and the density of the second intermediate layer ranges from 500 to 1500 KG/m3;

4. The middle layer can be alternately arranged, wherein the two layers of different density, such as one-time interlacing, form a three-layer composite floor with the panel; if the two intermediate layers with different densities are interlaced multiple times, a multi-layer composite is formed with the panel. floor;

5. The floor covering may be natural or artificial materials including, but not limited to, plastic, glass, rubber, PVC, PP, bamboo, or other wood materials, and any of stone, marble, and the like.

6. Recycled rubber or recycled plastic can be selected from soles, tires, cables, plastic waste, etc.
