Description

[Detailed Description of the Invention] The present invention relates to interior materials used for floors, walls, etc. of buildings.

BACKGROUND ART Conventionally, materials in which ethylene resin foam sheets are laminated on the back side of surface materials such as carpets and wallpapers have been used as interior materials for buildings because of their excellent heat insulation, soundproofing, and cushioning properties. This interior material is adhered to surfaces such as floors and walls using an adhesive or double-sided adhesive tape.

However, when the interior material is peeled off to adjust its position or to be replaced, the surface strength of the ethylene resin foam sheet is weak, and parts of the foam sheet break and cause damage to floors, walls, etc. The remaining work efficiency was extremely poor. Additionally, when interior materials are partially adhered using double-sided adhesive tape, the ethylene resin foam sheet expands and contracts due to changes in temperature, humidity, etc., resulting in blisters, wrinkles, etc., which impairs the appearance. There were flaws.

The purpose of the present invention is to eliminate the drawbacks of the conventional interior materials mentioned above, and to provide an interior material that is easy to peel, has high efficiency in construction work and reapplying work, and does not cause blisters, wrinkles, etc.

That is, the gist of the present invention resides in an interior material in which paper is laminated on the back side of an ethylene resin foam sheet on which a surface material is laminated, and a polyethylene film is further laminated on the back side of the paper.

Hereinafter, the interior material of the present invention will be explained with reference to the drawings.

In the figure, reference numeral 1 is an ethylene resin foam sheet, and the surface of the foam sheet 1 is covered with a carpet, a floor surface material such as a cushion floor material made of vinyl chloride resin foam, etc., a surface material 2 such as wallpaper, etc. A paper 3 such as kraft paper is laminated on the back side of the foam sheet 1, and a polyethylene film 4 is further laminated on the back side of the paper 3.

The ethylene resin foam sheet 1 is a foam sheet made of ethylene resin, and the ethylene resin may include polyethylene, a mixture of polyethylene as a main component with other polymers, a copolymer as a main component of ethylene, etc. can be given. Examples of the above copolymer include ethylene vinyl acetate copolymer,
Examples include ethylene vinyl chloride copolymer.
Further, the foam sheet 1 is preferably a closed-cell foam sheet since it has excellent heat insulation properties, sound insulation properties, etc., and a crosslinked foam sheet is particularly preferred. Further, the foaming ratio of the foamed sheet 1 is preferably 10 to 40 times.

It is preferable that the paper 3 has good dimensional stability with little expansion and contraction due to changes in temperature, humidity, etc., and kraft paper is particularly preferable because it is inexpensive and strong.

As a method of laminating the ethylene resin foam sheet 1, the surface material 2, and the paper 3, any known method such as a heat fusion method or an adhesive bonding method can be adopted, but the heat fusion method is simple and preferred. . When laminating the paper 3 and the polyethylene film 4 on the back side of the ethylene resin foam sheet 1, it is especially necessary to use paper with polyethylene films laminated on both sides and heat fusion bonding between the paper 3 and the polyethylene film 4 on the back side of the ethylene resin foam sheet 1. It is easy and preferable to do it.

In order to apply the interior material of the present invention to floors, walls, etc., it can be adhered with adhesive, double-sided adhesive tape, etc. Even when the interior material is replaced or peeled off for position adjustment during construction, the foam sheet 1 is reinforced by the paper 3 and the polyethylene film 4, and the foam sheet 1 is not destroyed.
Peeling is easily performed on the surface of the polyethylene film 4. Furthermore, since the paper 3 with good dimensional stability is laminated, the interior material will not swell or wrinkle even if the temperature, humidity, etc. change. The interior material of the present invention is particularly effective when used on floors.

Note that the polyethylene film 4 does not need to be made of pure polyethylene; it may be mixed with some other resin, or may be a copolymer with other monomers.

As mentioned above, the interior material of the present invention is made by laminating paper on the back side of an ethylene resin foam sheet and further laminating a polyethylene film on the back side of the paper, so it can be adhered to the construction surface with adhesive, double-sided adhesive tape, etc. It is easy to peel off even if it is removed, making the construction work and reapplying work more efficient, and does not cause blisters or wrinkles.
