本発明は、塩化ビニル系樹脂層を含む壁紙及びその製造方法に関する。 The present invention relates to wallpaper containing a vinyl chloride resin layer and a method for producing the same.
従来より、マンション、一般家屋等の建築物の壁、天井、柱等の表面を装飾する目的で、塩化ビニル樹脂層を基材上に積層した塩化ビニル壁紙が一般的に使用され、特に、意匠性、耐不陸性（隠ぺい性とも称される。）等の点から、発泡塩化ビニル樹脂層を積層した塩化ビニル壁紙が広く使用されている。一方、壁紙は、比較的に長期間使用されるため、耐久性のための表面強度が要求される。例えば、特許文献１には、ペースト用塩化ビニル系樹脂を含む発泡層の表面に樹脂コーティング層を形成し、表面を強化した壁紙が提案されている。特許文献２には、重合度が１０００以上の塩化ビニル系樹脂を含み、坪量５０ｇ/ｍ2以上２８０ｇ/ｍ2以下かつ３倍以上の発泡倍率である発泡した樹脂層形成された壁紙が記載されている。
Conventionally, vinyl chloride wallpapers in which a vinyl chloride resin layer is laminated on a substrate have been generally used for the purpose of decorating the surfaces of walls, ceilings, columns, etc. of buildings such as condominiums and ordinary houses. In particular, vinyl chloride wallpapers in which a foamed vinyl chloride resin layer is laminated are widely used in terms of design and unevenness resistance (also called concealment). On the other hand, since wallpapers are used for a relatively long period of time, surface strength is required for durability. For example,
最近では、施工性の観点から、壁紙の軽量化が求められているが、壁紙の軽量化に伴い、隠ぺい性や下地追従性が劣るという問題があった。 Recently, there has been a demand for lighter wallpaper for ease of application, but as wallpaper becomes lighter, there are problems with its concealment and ability to conform to the substrate.
本発明は、上記従来の問題を解決するため、意匠性及び表面強度が良好であるとともに、軽量性、隠ぺい性、下地追従性及び難燃性にも優れる壁紙及びその製造方法を提供する。 In order to solve the above-mentioned problems of the conventional art, the present invention provides wallpaper that has good design and surface strength, as well as light weight, hiding power, base conformability, and flame retardancy, and a manufacturing method thereof.

以下、図面等に基づいて、本発明の実施の形態を具体的に説明するが、本発明は以下に説明する実施形態に限定されるものではない。 The following describes in detail the embodiment of the present invention with reference to the drawings, but the present invention is not limited to the embodiment described below.
図１は本発明の１以上の実施形態に係る壁紙の模式的断面図である。該実施形態の壁紙１は、基材２と、基材２上に形成された塩化ビニル系樹脂層３を含む。塩化ビニル系樹脂層３は、発泡後にエンボス加工されている。
Figure 1 is a schematic cross-sectional view of wallpaper according to one or more embodiments of the present invention.
基材２としては、一般的に壁紙の基材として使用されるものであればよく、特に限定されない。例えば、紙、布帛、不織布、合成樹脂シート（合成樹脂フィルムを含む。）、又はこれらの複合素材等を用いることができる。紙としては、例えば、塗工紙、ケナフ紙、普通紙、再生紙、和紙、上質紙、クレープ紙、グラシン紙、トレーシングペーパー、キャスト紙、コーテッド紙、合成紙等の各種の紙材が挙げられる。布帛としては、例えば、天然繊維、合成繊維、半合成繊維、再生繊維等で構成された編物や織物が挙げられる。不織布としては、例えば、天然繊維、合成繊維、半合成繊維、再生繊維等で構成された不織布が挙げられる。合成樹脂シートとしては、ポリエチレンテレフタレート、ポリエチレン、ポリプロピレン等のポリオレフィン、塩化ビニル系樹脂、オレフィン系熱可塑性エラストマー、ＡＢＳ樹脂等の合成樹脂製で構成されたシート等が挙げられる。
The
基材２は、軽量性の観点から、重量が８０ｇ／ｍ2以下であることが好ましい。また、壁紙を張り替える際の壁紙の剥がれ易さ（耐剥離性）を向上させる観点から、５５ｇ／ｍ2以上であることが好ましい。基材２の重量は、６０ｇ／ｍ2以上７５ｇ／ｍ2以下であることがより好ましい。
From the viewpoint of light weight, the weight of the
基材２は、特に制限されないが、剛性の観点から、厚さが０．０８ｍｍ以上０．１５ｍｍ以下であることが好ましく、０．１０ｍｍ以上０．１３ｍｍ以下であることがより好ましい。
The
基材２としては、厚さが０．１０ｍｍ以上０．１３ｍｍ以下であり、重量が６０ｇ／ｍ2以上８０ｇ／ｍ2以下である普通紙を用いることが特に好ましい。
As the
塩化ビニル系樹脂層３は、重量が１０５ｇ／ｍ2以上１４５ｇ／ｍ2以下である。重量が１０５ｇ／ｍ2未満であると、壁紙１の厚みｈが薄くなりすぎ、隠ぺい性、下地追従性及び表面強度が劣る。一方、重量が１４５ｇ／ｍ2を超えると、壁紙の難燃性が低下する。塩化ビニル系樹脂層３の重量が上述した範囲内であると、軽量性が良好であるとともに、隠ぺい性、下地追従性、表面強度及び難燃性にも優れる壁紙が得られる。塩化ビニル系樹脂層３の重量は、好ましくは１１５ｇ／ｍ2以上であり、より好ましくは１２５ｇ／ｍ2以上であり、さらに好ましくは１３５ｇ／ｍ2以上である。
The weight of the vinyl chloride resin layer 3 is 105 g/m 2 or more and 145 g/m 2 or less. If the weight is less than 105 g/m 2 , the thickness h of the
塩化ビニル系樹脂層３において、塩化ビニル系樹脂は平均重合度が１２００以上１５００以下である。塩化ビニル系樹脂の平均重合度が１２００未満であると、壁紙の下地追従性が劣る。一方、塩化ビニル系樹脂の平均重合度が１５００を超えると、発泡セルが不良となり、柄意匠性や下地追従性や表面強度も劣る。塩化ビニル系樹脂は平均重合度が上述した範囲であることで、壁紙の柄意匠性、下地追従性や表面強度が良好になるとともに、塩化ビニル系樹脂層における発泡セルも均一になる。塩化ビニル系樹脂の平均重合度は、好ましくは１２５０以上１５００以下であり、より好ましくは１２５０以上１４５０以下である。塩化ビニル系樹脂の平均重合度は、ＪＩＳ Ｋ ６７２０－２：１９９９に準じて測定する。 In the vinyl chloride resin layer 3, the vinyl chloride resin has an average degree of polymerization of 1200 or more and 1500 or less. If the average degree of polymerization of the vinyl chloride resin is less than 1200, the wallpaper will have poor conformability to the substrate. On the other hand, if the average degree of polymerization of the vinyl chloride resin exceeds 1500, the foam cells will be poor, and the pattern design, conformability to the substrate, and surface strength will also be poor. By having the average degree of polymerization of the vinyl chloride resin in the above-mentioned range, the wallpaper will have good pattern design, conformability to the substrate, and surface strength, and the foam cells in the vinyl chloride resin layer will be uniform. The average degree of polymerization of the vinyl chloride resin is preferably 1250 or more and 1500 or less, and more preferably 1250 or more and 1450 or less. The average degree of polymerization of the vinyl chloride resin is measured in accordance with JIS K 6720-2:1999.
