Description

A multi-layer sound-insulating and shock-absorbing composite floor

technical field

The utility model relates to a multi-layer sound-insulating and shock-absorbing composite floor, which belongs to the technical field of floors.

Background technique

Most of the existing floors are composited by a single material, and its biggest shortcoming is that it cannot solve the problem of sound insulation and shock absorption. Previously, low-density foam materials had to be used to solve the problem of shock absorption. However, due to the relatively high compression rate of low-density foam materials, it is easy to cause uneven floor thickness and dents, which will affect the use of the product. How to make the product have the function of shock absorption while improving the sound insulation performance. All of these cannot be achieved by products with a single structure or material.

Contents of the invention

The utility model can overcome the deficiencies in the prior art, and discloses a multi-layer sound-insulating and shock-absorbing composite floor that can improve the sound-insulating performance and also has the function of shock-absorbing.

The utility model can be realized by taking the following technical solutions:

A multi-layer sound-insulating and shock-absorbing composite floor at least includes a floor surface layer, a bottom layer for improving the sound insulation and shock absorption of the floor, and an intermediate layer of not less than one layer between the surface layer and the bottom layer.

The middle layer and the bottom layer are at least made of rubber material and recycled polyurethane, wherein the rubber material can be selected from general rubber, plastic, foamed rubber and recycled rubber or plastic, and the polyurethane can be selected from rigid foam polyurethane and soft foam polyurethane.

The density range of the bottom layer is 500-1500 KG/m3; the middle layer can adopt a single middle layer with a density range of 200-900 KG/m3, or a density range of 200-900 KG/m3 and a density range of 500- 1500 KG/m3 staggered composite middle layer, when the composite layer middle layer is used, the density connected to the bottom layer is different from that of the bottom layer.

The floor surface layer can be natural or artificial materials, including but not limited to any one of plastic, glass, rubber, PVC, PP, bamboo wood, or other wooden materials, as well as stone materials such as ceramic tiles and marble.

The utility model buffers the pressure borne by the floor through the structure of the multi-layer composite body, and achieves the effect of sound insulation and shock absorption.
