JPS6032757B2 - Laminated materials for floors and walls - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminate for floors and walls that is directly attached to the surface of concrete floors, walls, and floor and wall panels.

For example, with conventional flooring materials that are installed directly on the surface of concrete floors or floor panels, printed vinyl is glued or welded to the surface of the base fabric, or a fixed thickness is attached to the back of the surface layer of only printed vinyl. There are those in which open-cell foamed synthetic resin is adhered or welded, and there are those in which a noncombustible material such as asbestos is adhered to the back side of this foamed synthetic resin.

However, in this type of structure, the cushioning material used is a single layer of open-cell foamed synthetic resin, which has weak restoring power and poor cushioning properties, making it feel hard and uncomfortable. .

In addition, such a structure has poor heat insulation and soundproofing effects, lacks durability, and has poor ventilation.

This is because the open-cell foamed synthetic resin is simply adhered or welded to the underside of the base fabric or the underside of the printed vinyl.

In addition, materials made of foamed synthetic resin or materials with asbestos adhered to the surface of foamed synthetic resin cause various difficulties during construction because they are weak against bending and easily break or are difficult to peel off.

That is, for example, when using a cutting board for cutting such flooring materials, it is difficult to cut to size because the foamed synthetic resin stretches when force is applied from above. Also, when removing flooring to replace it after installing it with adhesive or adhesive tape,
It is difficult to peel off uniformly because it is torn, and the work efficiency is extremely poor. The present invention aims to eliminate these various drawbacks.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

Reference numeral 1 denotes a laminate flooring member that is directly attached to the surface of a concrete floor or floor panel board, and this flooring material is composed of a surface layer A, an intermediate layer B, and a bottom layer C.

A member 3 printed on the surface of the base fabric 4, such as printed vinyl, is adhered or deposited on the surface layer A, and a transparent or translucent covering member 2, such as a vinyl film, is adhered to the surface of the member 3. Or it is covered by a desired means such as welding.

In addition, when the base fabric 4 is directly printed, the printing member 3 may be removed and the surface of the base fabric 4 may be covered with the covering member 2. Further, the surface layer A may be only the surface-treated printed member 3. The intermediate layer B located on the back surface of the surface layer A consists of an open-cell foamed synthetic resin layer in the upper layer and a closed-cell foamed synthetic resin layer in the lower layer, and the open-celled foamed synthetic resin includes, for example, foamed polyurethane. As the closed-cell foamed synthetic resin, for example, foamed polyethylene is preferably used.

Further, in order to improve the cushioning properties, it is preferable that the upper open-cell foamed synthetic resin layer is approximately twice or more thick than the lower closed-cell foamed synthetic resin layer.

Furthermore, the upper and lower foamed synthetic resin layers may be stacked alternately in multiple stages.

Further, it is composed of a bottom layer C made of a covering member 8 such as a polyethylene film or a fabric, which is adhered or welded to the back surface of the intermediate layer B.

Furthermore, between the intermediate layer B and the bottom layer C, a member 7 made of a relatively hard material such as woven fabric such as kraft paper or Kuff cloth may be inserted and bonded or welded. , middle layer B, and bottom layer C are integrally adhered or bonded in order by heat welding or adhesive.

Reference numeral 9 denotes a through hole that penetrates from the surface layer A to the covering member 8 of the bottom layer C, and is provided as necessary. The through hole 9
are about the thickness of a pin or needle, and are provided in arbitrarily large numbers. Laminated materials with the above structure can be used for concrete floors, walls,
When directly attaching to a panel board, adhesive tape or adhesive is applied or glued to the surface of the concrete floor, wall, etc. or the back surface of the laminate to fix it.

According to the present invention configured as described above, since the intermediate layer is made of two or more layers of an open-cell foamed synthetic resin layer and a closed-cell foamed synthetic resin layer, even flooring materials of the same thickness as conventional ones can be used. The cushioning properties have become much better.

In addition, because the upper layer is made of an open-cell foamed synthetic resin layer and the lower layer is a closed-celled foamed synthetic resin layer, it has a large restoring force, and the heat insulation and soundproofing effects are increased.

It also reduces impact noise and prevents moisture. Furthermore, since relatively hard paper or fabric is inserted between the middle layer and the bottom layer, it is strong against bending and has good dimensional stability when cutting, resulting in accurate dimensions when cutting and improved work efficiency. improves.

In addition, since the back side of the laminated material is a smooth film, etc., it can be peeled off evenly, and the work when peeling is easy. It is also easy to work when replacing, and the laminated material itself has moisture and water resistance. is good.

Furthermore, when through holes were provided, air permeability was improved and water resistance was also increased.

Furthermore, since each member is made of a light material, it is lighter than the conventional one with the same thickness.
