Abstract

(57) [Abstract] [Purpose] To provide a wall covering material having a practical antifouling property and a high-grade feeling without the adhesive penetrating the surface. [Structure] A wallpaper in which a surface fiber sheet such as a woven fabric, a knitted fabric or a non-woven fabric treated with a fluorine-based processing agent and a flame-retarded backing paper are integrated with a vinyl acetate adhesive.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a wall covering material having excellent antifouling property such as wallpaper.

[0002]

[Prior Art]

 Conventional wall coverings generally consist of a surface material, an adhesive layer, and a backing paper, and most of the surface material is a polyvinyl chloride sheet. Has been applied. In many cases, a woven, knitted, or non-woven surface material is preferred as a material with a higher-grade appearance, and wall covering materials made of rayon fabric are mainly used.

[0003]

[Problems to be solved by the device]

 However, the surface material of such a fiber sheet is easily soiled, and the dirt cannot be wiped off easily compared to a vinyl chloride sheet, so handling is inconvenient and careful work is required. Workability during construction is poor, and it is difficult to maintain the aesthetic appearance even after construction for the same reason. Further, when the surface material is thin, an adhesive for integrating with the backing material penetrates, the surface material becomes sticky to the touch, and the hue changes depending on the degree of penetration. An object of the present invention is to solve the above-mentioned conventional drawbacks and provide a wall covering material having a practical antifouling property.

[0004]

[Means for Solving the Problems]

 That is, the present invention is a wall covering material in which an adhesive layer and a backing paper are integrated with a surface fiber sheet treated with a fluorine-based processing agent (hereinafter sometimes simply referred to as a fiber sheet).

There are various kinds of fibers used for the surface fiber sheet in the present invention, but hydrophobic fibers, for example, polyester fibers are preferably used. The fluorine-based processing agent applied to the fiber sheet is generally a fluorine-based resin having a fluorocarbon chain, which contains a crosslinkable monomer component in the molecular chain and further has a crosslinking agent added to the resin. It is usually attached to the fiber as an emulsion, which is bridged by heating and fixed to the fiber.

As a method of applying the fluorine-based processing agent to the fiber sheet, a method of immersing the raw material fiber in the processing agent emulsion, a method of immersing the woven material, a knitted fabric, a non-woven fabric or the like in the processing agent emulsion, Alternatively, there is a method of spraying the surface fiber sheet after forming the wall covering material, but the method is not limited to these methods. However, the dipping method is preferred because it is more difficult for the adhesive to penetrate into the surface of the fiber sheet when the processing agent is applied to the surface of the fiber sheet (back surface) facing the adhesive layer. When the dipping method is used, fluorine treatment may be performed at the same time as the dyeing treatment.

The backing paper is integrated with the surface sheet in order to provide ease of handling during construction and packaging, and shape stability of the wall covering material. Generally, flame-retardant paper is used. To be done. This integration is performed by adhesion, and vinyl acetate type and acrylic vinyl acetate type are used as the adhesive. In the wall covering material of the present invention, the surface fibrous sheet can be further subjected to a flame retardant treatment. In this case, the above-mentioned fluorine-based treating agent is mixed with the flame retardant, and the antifouling by the flame-retardant treatment and the fluorine-based treating agent is performed. Processing can be performed simultaneously.

FIG. 1 is a schematic cross-sectional view of a wall covering material of the present invention, wherein 1 is a fiber sheet treated with a fluorine-based processing agent, 2 is an adhesive layer, and 3 is a backing paper. The fiber sheet is integrated with the backing paper via an adhesive layer.

[0009]

[Effect of the device]

 The wall covering material of the present invention has a water-repellent / oil-repellent property due to the fluorine-based processing agent, has little dirt adhesion due to oil and water on the surface, and exhibits antifouling property for a long period of time. It does not infiltrate from the inside to contaminate the wall covering material, and therefore the surface feeling of the fiber sheet is not discolored or discolored, and the high-grade feeling of the fiber sheet surface material is fully exhibited.

【Example】

 Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited thereto. Example A woven fabric made of polyester fibers was dyed, and the woven fabric was dipped and cured using Asahi Guard AG710 (fluorine-based processing agent) manufactured by Asahi Glass Co., Ltd. to obtain a surface fiber sheet. A flame-retardant backing paper was bonded and integrated on the back surface of this sheet using a vinyl acetate adhesive, and a phosphorus-based flame retardant was applied to the surface sheet to form a wall covering. With respect to the obtained wall covering material, water repellency was examined by the DuPont method, and oil repellency was examined by the AATCC118 method. As a result, the initial performance was water repellency grade 8 and oil repellency grade 6, and the water repellency after fade irradiation (63 ° C, 40 hours) was grade 9 or higher, and the oil repellency grade 6 was excellent. Oiliness was observed.
