Description of the Related Art There is known a soundproof flooring material in which a synthetic resin foam or the like having elasticity is laminated on the back surface of a wooden base material on which a veneer or the like is adhered as a surface decorative material to improve cushioning and soundproofing. (Japanese Utility Model Laid-Open No. 50-49917, Japanese Utility Model Application Laid-Open No. 61-47)

No.-132038). These soundproof floor materials are adhered to a floor surface such as a concrete slab surface or a discarded plywood using an adhesive to form a floor surface.

十分となる不都合が生じている。It is known that the use of a nonwoven fabric of a certain thickness (preferably about 3 to 6 mm) as the back cushioning material is advantageous because it has the advantage of high soundproofing for the small amount of sinking. However, in general, the adhesive used when attaching the soundproofing floor material to the floor base surface easily penetrates into the inside of the nonwoven fabric, and the adhesive permeated into the nonwoven fabric layer is hardened, so that the cushioning property and the soundproofing property are reduced. . For this purpose, a resin sheet is attached to the back surface of the nonwoven fabric, and the resin sheet is attached to the floor base surface via the resin sheet. This can prevent the adhesive from penetrating into the nonwoven fabric and also prevent water absorption and moisture absorption. However, on the other hand, there is a disadvantage that the adhesiveness to the floor substrate is insufficient.

The adhesive may also penetrate into the non-woven fabric from the side to reduce the cushioning property and the soundproofing property.

It is possible to effectively prevent the adhesive from penetrating into the non-woven fabric which is the cushioning material at the time of attaching to the ground, thereby providing a soundproof flooring material which does not cause a decrease in soundproof performance. It is in.

0, and the thermoplastic resin layer 12 and the nonwoven fabric layer 11 are laminated on the back surface in that order.

High adhesiveness between the soundproofing floor material and the floor base surface is ensured. On the other hand, since the applied adhesive is prevented from penetrating into the nonwoven fabric layer 30 functioning as a cushioning material by the thermoplastic resin film 12, it is possible to avoid a decrease in the cushioning property and the soundproofing property, and also to prevent moisture from flowing from the floor base surface. Absorption can also be avoided.

There is no substantial decrease in cushioning and soundproofing. For bonding the nonwoven fabric layer 30 to the thermoplastic resin layer 12 and for bonding the nonwoven fabric sheet 11 to the thermoplastic resin layer 12, an appropriate adhesive may be used. Preferably, a hot melt resin is interposed as the adhesive layer. . This facilitates integration with a nonwoven fabric layer as a cushioning material in a single step by thermocompression bonding.

Is used. The three-layer sheet 10 can be easily laminated by thermocompression bonding to the back surface of the nonwoven fabric layer 30 with the hot melt resin layer 13 side as the nonwoven fabric layer 30 side, and the production of a soundproof flooring material is extremely easy. . Also, even after pasting to the floor base surface, the buffering property and the soundproofing property do not decrease.

ト１１ａにより阻止されるからである。In a preferred embodiment, as also shown in FIG. 2, a nonwoven fabric sheet 11a is disposed between the wood substrate 50 and the nonwoven fabric layer 30. The adhesion between the wooden base material 50 and the nonwoven fabric layer 30 as a cushioning material is sufficient with a small amount of adhesive compared to the adhesion to the floor base, and the wooden base material 50 and the nonwoven fabric layer 30 as a cushioning material are directly bonded. Even if adhesive lamination with the agent does not substantially reduce the buffering property, soundproofing,
By disposing the nonwoven fabric sheet 11a between the two,
The penetration of the adhesive into the nonwoven fabric layer 30 as a cushioning material is largely avoided, and a decrease in cushioning and soundproofing properties can be reliably avoided.
The reason is that the adhesion between the nonwoven fabric layer 30 as a cushioning material and the nonwoven fabric sheet 11a is sufficient with a small amount of adhesive, and the penetration of the adhesive into the nonwoven fabric layer 30 can be neglected. This is because the nonwoven fabric sheet 11a prevents the adhesive between the base material 11a and the wood substrate 50 from penetrating to the nonwoven fabric layer 30.

In this case, the production of the soundproofing floor material is facilitated, and particularly when a three-layer sheet is used,
The adhesive can more reliably be prevented from penetrating into the nonwoven fabric layer functioning as a cushioning material.

The method of producing the layer sheet 20 or the three-layer sheet 10 in which the nonwoven fabric sheet 11, the thermoplastic resin layer 12, and the hot melt resin layer 13 are integrally laminated in this order in advance is arbitrary, but as described above. In the case of a two-layer sheet, a method in which the hot melt resin flows out like a flow coater, and is applied by passing through a nonwoven sheet and cured, is preferable. Also,
Where the thermoplastic resin flows out like a flow coater, it is applied and cured by passing through a nonwoven sheet, and further, where the hot melt resin flows out like a flow coater, it passes through the sheet It is preferable to apply and cure them. According to this manufacturing method, since the bonding between the thermoplastic resin layer and the nonwoven fabric sheet is automatically performed, it is unnecessary to prepare an adhesive. By using the two-layer sheet 20 or the three-layer sheet 10 integrated in this way, the manufacturing process of the soundproof flooring material becomes extremely easy.
