Description

本考案は基層シートの両面に溶融接着層を介して表層フィルムを貼り合わせたフィルム貼合障子紙に関するものである。   The present invention relates to a film-bonded shoji paper in which a surface layer film is bonded to both surfaces of a base layer sheet via a molten adhesive layer.

従来、この種のフィルム貼合障子紙においては、溶融接着層が表層フィルムと異なる素材からなる。例えば、下記の特許文献１に示すように、表層フィルムがポリプロピレンからなり、溶融接着層がポリエステルからなる。基層シートの両面に溶融接着層を介して表層フィルムを貼り合わせる際には、表層フィルムにアンカー剤を塗布した後、その表層フィルムを溶融接着層により基層シートに接着して、接着強度を高めていた。
特開２００４−１１４６５３号公報 Conventionally, in this kind of film-bonded shoji paper, the melt adhesive layer is made of a material different from the surface film. For example, as shown in the following Patent Document 1, the surface layer film is made of polypropylene, and the fusion bonding layer is made of polyester. When the surface layer film is bonded to both sides of the base layer sheet via the melt adhesive layer, after applying the anchor agent to the surface layer film, the surface layer film is adhered to the base layer sheet by the melt adhesive layer to increase the adhesive strength. It was.

この考案は、フィルム貼合障子紙において、表層フィルムにアンカー剤を塗布することなく、基層シートと表層フィルムとの接着性を強靭なものにすることを目的としている。   This device aims at making the adhesiveness of a base layer sheet and a surface layer film strong, without apply | coating an anchor agent to a surface layer film in a film bonding shoji paper.

後記実施形態の図面（図１）の符号を援用して本考案にかかるフィルム貼合障子紙を説明する。
請求項１の考案にかかるフィルム貼合障子紙においては、基層シート１の両面に溶融接着層２を介して表層フィルム３を貼り合わせ、溶融接着層２が表層フィルム３と同素材からなる。この表層フィルム３及び溶融接着層２の素材としては、例えば、請求項２の考案にかかるポリプロピレンや、請求項３の考案にかかるポリエチレンや、請求項４の考案にかかるポリエステルや、請求項５の考案にかかるナイロンや、請求項６の考案にかかるエチレン酢酸ビニルや、請求項７の考案にかかる塩化ビニルなどを採用することができる。 A film-bonded shoji paper according to the present invention will be described with reference to a drawing (FIG. 1) of an embodiment described later.
In the film-bonded shoji paper according to the invention of claim 1, the surface film 3 is bonded to both surfaces of the base layer sheet 1 via the melt adhesive layer 2, and the melt adhesive layer 2 is made of the same material as the surface film 3. Examples of the material of the surface film 3 and the melt adhesion layer 2 include, for example, polypropylene according to the invention of claim 2, polyethylene according to the invention of claim 3, polyester according to the invention of claim 4, and claim 5 Nylon according to the invention, ethylene vinyl acetate according to the invention according to claim 6, vinyl chloride according to the invention according to claim 7, and the like can be employed.

本考案は、フィルム貼合障子紙において、表層フィルム３にアンカー剤を塗布することなく、基層シート１と表層フィルム３との接着性を強靭なものにすることができる。   This invention can make the adhesiveness of the base layer sheet 1 and the surface layer film 3 strong without apply | coating an anchor agent to the surface layer film 3 in a film bonding shoji paper.

本実施形態に係るフィルム貼合障子紙を示す模式図である。It is a schematic diagram which shows the film bonding shoji paper which concerns on this embodiment.

以下、本考案の一実施形態に係るフィルム貼合障子紙について説明する。
図１に示すフィルム貼合障子紙においては、基層シート１の両面に溶融接着層２を介して表層フィルム３が貼り合わされている。この溶融接着層２は表層フィルム３と同素材からなる。この基層シート１は紙素材であって、障子紙としての風合いや光の透過性を考慮して、その紙素材にレーヨン繊維やアクリル繊維やポリエステル繊維やビニロン繊維などの合成繊維と蛍光染料とを配合している。この表層フィルム３及び溶融接着層２の素材としては、ポリオレフィン系の熱可塑性樹脂であるポリプロピレンを採用している。そのほか、ポリオレフィン系の熱可塑性樹脂であるポリエチレンを採用してもよい。そのほかの熱可塑性樹脂として、ポリエステルやナイロンやエチレン酢酸ビニルや塩化ビニルなどを採用することができる。 Hereinafter, a film-bonded shoji paper according to an embodiment of the present invention will be described.
In the film-bonded shoji paper shown in FIG. 1, the surface layer film 3 is bonded to both surfaces of the base layer sheet 1 via the melt adhesive layer 2. The melt adhesive layer 2 is made of the same material as the surface layer film 3. This base layer sheet 1 is a paper material, and considering the texture as a shoji paper and the light transmission property, synthetic paper such as rayon fiber, acrylic fiber, polyester fiber and vinylon fiber and fluorescent dye are added to the paper material. It is blended. As a material for the surface film 3 and the melt adhesion layer 2, polypropylene which is a polyolefin-based thermoplastic resin is employed. In addition, polyethylene which is a polyolefin-based thermoplastic resin may be employed. As other thermoplastic resins, polyester, nylon, ethylene vinyl acetate, vinyl chloride, or the like can be used.

本実施形態では、基層シート１（紙素材）の両面に、表層フィルム３と同素材（ポリプロピレンやポリエチレンやポリエステルやナイロンやエチレン酢酸ビニルや塩化ビニルなど）からなる溶融接着層２を介して表層フィルム３を貼り合わせたので、表層フィルム３にアンカー剤を塗布することなく、基層シート１と表層フィルム３との接着性を強靭なものにすることができる。また、アンカー剤として有機溶剤を使用している従来の場合と比較して、環境負荷を低減させることができる。なお、表層フィルム３としてポリプロピレンを採用すると、耐水強度が高く、強い衝撃力にも耐えられるものとなる。   In this embodiment, the surface layer film 1 is formed on both sides of the base layer sheet 1 (paper material) via the melt adhesion layer 2 made of the same material (polypropylene, polyethylene, polyester, nylon, ethylene vinyl acetate, vinyl chloride, etc.) as the surface layer film 3. Since 3 is bonded together, the adhesion between the base layer sheet 1 and the surface layer film 3 can be made strong without applying an anchor agent to the surface layer film 3. Moreover, an environmental load can be reduced compared with the conventional case which uses the organic solvent as an anchor agent. In addition, when polypropylene is used as the surface layer film 3, the water resistance strength is high, and it can withstand a strong impact force.
