[0039] The first buffer layer 14 with porous and / or reticular structure provided in the present application can make the noise reflect and refract in the porous or honeycomb structure for many times, thereby attenuating the sound and prolonging the sound wave propagation path, achieving the effect of effectively reducing noise propagation. At the same time, the first buffer layer 14 with porous and / or reticular structure has compressibility, which can also alleviate the impact effect of the contact between the layers of the floor and the floor and the ground, thereby reducing the effect of noise propagation.

[0040] Specifically, the porous structure includes a closed-cell porous structure, a semi-closed-cell porous structure, and an open-cell porous structure; the net structure includes a honeycomb structure and a net accumulation structure.

The second buffer layer 16 can also be a compressible natural material, such as felt, cotton, wool, mycelium, hemp, cork, and / or the like. Cork is composed of many small holes or cells inside, which are called "air chambers", and this structure of cork makes it have good temperature, sound and vibration insulation performance, which can effectively isolate external noise and vibration.

It is appreciated that open cell porous structure or semi-closed cell porous structure has the advantage of improved sound absorption. Optionally, the first cushioning layer 14 is a foamed layer, in which case the foam pore size and open cell rate of the foamed material of the first cushioning layer 14 can be controlled by the foaming reaction, in particular by adjusting the amount of foaming catalyst, to achieve open cell, semi-open cell and closed cell. Optionally, the first cushioning layer 14 can also be a substantially solid non-foamed layer, in which case the best results are obtained using a material selected from the group of flexible polymers and elastomers, such as rubber, latex, acrylic elastomeric epoxy, cis-polyisoprene (natural rubber, NR), cis-polybutadiene (butadiene rubber, BR), nitrile rubber (NBR), styrene butadiene rubber (SBR), rubber, latex and / or ethylene propylene monomer (EPM). When the first cushioning layer 14 comprises a compressible natural material, the material can be selected from the group of, for example, felt, cotton, wool, mycelium, hemp, cork and / or the like. Cork is composed of many small holes or cells inside, which are called "air chambers", and this structure of cork provides it with good temperature, sound and vibration insulation properties, effectively isolating external noise and vibrations. These examples are non-limiting and any similar foam material having equivalent material properties can be applied.

By adding reinforcing layers 132 within the first carrier 13, the overall strength of the first carrier is increased, the dimensional stability of the first carrier at high temperatures is increased, and shrinkage is reduced.

[0045] Specifically, the first carrier 13 is one or more of a high-density fiberboard layer, a wood-plastic composite material layer, a polyvinyl chloride resin layer, a high-end vinyl material layer (LVT base layer), a terephthalate layer (PET base layer), a polypropylene resin layer (PP base layer), or a polyethylene terephthalate-1, 4-cyclohexane dimethanol layer (PETG base layer).

[0046] Specifically, the first carrier 13 is one or more of a high-density fiberboard layer, a wood-plastic composite material layer, a polyvinyl chloride resin layer, a high-end vinyl material layer (LVT base layer), a terephthalate layer (PET base layer), a polypropylene resin layer (PP base layer), or a polyethylene terephthalate-1, 4-cyclohexane dimethanol layer (PETG base layer).

The advantage of the latter embodiment (consisting essentially of the above-mentioned scratch resistant thermoset resin inherent to the carrier layer) is that the urea-formaldehyde also acts as a relatively scratch resistant layer. Typically, the thickness of the wear layer structure is in the range of 0.1 mm to 2.0 mm.

In this case, the degree of deformation of the first carrier and the first cushioning layer when a person steps on them is greater, and the resilience of the first cushioning layer and the first carrier as a whole when the foot is removed is best, and the silent effect is better.

[0052] The polyvinyl chloride resin layer includes a foamed chloroethylene base layer or a rigid polyvinyl chloride base layer, etc., the second carrier 15 has an elastic modulus in the range of 2000 MPa to 3000 MPa when the foamed chloroethylene base layer, and the second carrier 15 has an elastic modulus in the range of 3000 MPa to 7000 MPa when the rigid polyvinyl chloride base layer.
