Description
本発明は、でんぷん糊等水性樹脂を用いて施工する、表面に発泡樹脂層を有する壁紙に関し、特には基材シートの水伸縮による施工後の各壁紙間のジョイント部分の隙間の改良に係わるものである。 The present invention relates to a wallpaper having a foamed resin layer on its surface, which is constructed using a water-based resin such as starch paste, and particularly relates to improvement in the joint gap between each wallpaper after construction by water expansion and contraction of the base sheet. It is.
従来、紙など天然繊維からなる基材シートの表面に、水酸化アルミニウム等の充填剤を配合した発泡ポリ塩化ビニル樹脂を設けた壁紙が知られている。 Conventionally, a wallpaper is known in which a foamed polyvinyl chloride resin in which a filler such as aluminum hydroxide is blended is provided on the surface of a base sheet made of natural fibers such as paper.
しかし、紙を基材とする場合には、湿気などの水分を吸うと、伸縮があり寸法安定性が出ない。 However, when paper is used as a base material, if moisture such as moisture is sucked, there is expansion and contraction and dimensional stability does not appear.
また、ポリエステル等のフィルムや不織布を基材とする場合は、その表面にポリ塩化ビニルゾルや水性エマルジョン樹脂をコーティングすると、紙にコーティングするようなアンカー作用がないので基材とコーティング面で密着できず、剥離してしまうという問題点があった。 In addition, when a film such as polyester or a non-woven fabric is used as a base material, if the surface is coated with polyvinyl chloride sol or aqueous emulsion resin, there is no anchoring action to coat paper, so the base material cannot be adhered to the coating surface. There was a problem of peeling off.
また、一般的に壁紙の施工で用いられるでんぷん糊等の水性樹脂は、水分が乾燥しにくく糊のタックが発現しない、前記コーティングができない理由と同じく密着がしにくく接着しくいという問題点があった。 In addition, water-based resins such as starch paste generally used for wallpaper construction have the problems that moisture is difficult to dry and tackiness of the glue does not occur, and that the coating is difficult to adhere, as well as the reason why the coating cannot be performed. It was.
本発明は、前記の課題を解決すべくなされたものでありその課題とするところは、通常施工で用いているでんぷん糊等の水性樹脂を用いることができ、さらにその水分を吸っても伸縮が少なく寸法安定性が優れており、しかも、コーティングによっても層間の密着性を十分に確保することができる壁紙を提供することを目的とする。 The present invention has been made to solve the above-mentioned problems, and the problem is that the aqueous resin such as starch paste used in normal construction can be used. An object of the present invention is to provide a wallpaper that is small in size and excellent in dimensional stability and that can sufficiently ensure adhesion between layers even by coating.
本発明の壁紙はこの課題を解決するため、請求項１記載の発明は、基材シートの表面に発泡樹脂層を設けてなる壁紙であって、前記基材シートが、ポリエステル繊維２５〜５０重量％、ポリエチレン繊維５〜１５重量％、麻５〜３０重量％および針葉樹、広葉樹からなる木材パルプから選ばれる繊維６５〜５重量％とからなる混抄紙であることを特徴とする壁紙である。 In order to solve this problem, the wallpaper of the present invention is a wallpaper in which a foamed resin layer is provided on the surface of a base sheet, and the base sheet has a polyester fiber of 25 to 50 weight. %, Polyethylene fiber 5 to 15% by weight, hemp 5 to 30% by weight, and 65 to 5% by weight of a fiber selected from wood pulp made of softwood and hardwood.
また請求項２記載の発明は、前記発泡樹脂層が発泡ポリ塩化ビニル樹脂層、発泡水性エマルジョン樹脂層もしくは発泡ポリオレフィン系樹脂層であることを特徴とする請求項１記載の壁紙である。 The invention according to claim 2 is the wallpaper according to claim 1, wherein the foamed resin layer is a foamed polyvinyl chloride resin layer, a foamed aqueous emulsion resin layer or a foamed polyolefin resin layer.
本発明の壁紙は、基材シートが、ポリエステル繊維２５〜５０重量％、ポリエチレン繊維５〜１５重量％、麻５〜３０重量％および針葉樹、広葉樹からなる木材パルプから選ばれる繊維６５〜５重量％とからなる混抄紙を用いている。従って、ポリエステルとポリエチレンの合成繊維３０重量％以上含んでいるので、吸湿、吸水による伸縮が極めて少なく、寸法安定性に優れており、しかも、麻、木材パルプからなる天然繊維を３０重量％以上含んでいるので、発泡樹脂層を形成する際に、押し出し方式やカレンダー方式のみならず、ポリ塩化ビニルゾルや水性エマルジョン樹脂等を用いたコーティング方式によっても、十分な密着性を容易に得ることができる。 The wallpaper of the present invention has a base sheet of 25 to 50% by weight of polyester fibers, 5 to 15% by weight of polyethylene fibers, 5 to 30% by weight of hemp, and 65 to 5% by weight of fibers selected from wood pulp consisting of softwood and hardwood. Is used. Therefore, it contains 30% by weight or more of synthetic fiber of polyester and polyethylene, so there is very little expansion and contraction due to moisture absorption and water absorption, excellent dimensional stability, and 30% by weight or more of natural fibers made of hemp and wood pulp. Therefore, when the foamed resin layer is formed, sufficient adhesion can be easily obtained not only by an extrusion method and a calendar method but also by a coating method using a polyvinyl chloride sol or an aqueous emulsion resin.
図１に本発明における壁紙の断面の構造を示す。混抄紙からなる基材シート１の表面に発泡樹脂層２を設けてなる。 FIG. 1 shows a cross-sectional structure of a wallpaper according to the present invention. A foamed resin layer 2 is provided on the surface of a base sheet 1 made of mixed paper.
本発明で用いる基材シートは、合成繊維であるポリエステル繊維、ポリエチレン繊維の複合と麻を含むパルプとの混抄紙である。 The base material sheet used in the present invention is a mixed paper of a composite of polyester fiber and polyethylene fiber which are synthetic fibers and pulp containing hemp.
本発明における基材シートに用いるポリエステル繊維、ポリエチレン繊維の割合は、ポリエステル繊維２５〜５０重量％及びポリエチレン繊維５〜１５重量％から選ばれる。ポリエステル繊維が２５重量％未満では水による寸法変化が大きくなり、また壁紙加工時の耐熱性が損なわれる。５０重量％を越えるとポリエステル繊維の特徴である剛性がつよくなり抄紙した際に毛羽立ちが起こり、面平滑性が失われる。ポリエチレン繊維５重量％未満では、加工時の熱で溶融しポリエステルの毛羽立ちを抑え込む働きが発現せず、１５重量％を越えると、加工時の熱で溶融する重量％が大きくなり、基材の伸び等があり、しわ等の原因となる。 The ratio of the polyester fiber and polyethylene fiber used for the base material sheet in the present invention is selected from 25 to 50% by weight of polyester fiber and 5 to 15% by weight of polyethylene fiber. If the polyester fiber is less than 25% by weight, the dimensional change due to water increases, and the heat resistance during wallpaper processing is impaired. If it exceeds 50% by weight, the rigidity characteristic of the polyester fiber is enhanced, and fluffing occurs when paper is made, and surface smoothness is lost. If it is less than 5% by weight of polyethylene fiber, it will not work to suppress fuzzing of polyester by melting with heat during processing. If it exceeds 15% by weight, the weight percent melted by heat during processing will increase and the elongation of the substrate will increase. And cause wrinkles.
前記基材シートにおける合成繊維の割合は合計で３０〜６５重量％が好ましい。３０重量％未満では、吸湿、吸水の際に伸縮し、０．３％以上の寸法変化を示すので、化粧シートの継ぎ目部分における目隙き又は突き上げ等の原因となり易い。一方、６５重量％を超えると、パルプ分が３５重量％未満と少ないので、発泡樹脂層をポリ塩化ビニルゾルや水性エマルジョン樹脂等を用いたコーティング方式にて形成する場合に、基材シートと発泡樹脂層との密着性が悪化する。 The total proportion of synthetic fibers in the base sheet is preferably 30 to 65% by weight. If it is less than 30% by weight, it expands and contracts during moisture absorption and water absorption, and exhibits a dimensional change of 0.3% or more, which is likely to cause gaps or push-ups in the joint portion of the decorative sheet. On the other hand, when it exceeds 65% by weight, the pulp content is less than 35% by weight. Therefore, when the foamed resin layer is formed by a coating method using a polyvinyl chloride sol or an aqueous emulsion resin, the base sheet and the foamed resin Adhesion with the layer deteriorates.
本発明における基材シートに用いる天然繊維としての麻は５〜３０重量％とし、針葉樹、広葉樹からなる木材パルプから選ばれる繊維は６５〜５重量％とする。麻が５重量％未満であると、ポリエステルの毛羽立ちが目立ち、３０重量％を越えると、施工時の腰が出すぎ、貼りにくくなる。 The hemp as a natural fiber used for the base material sheet in the present invention is 5 to 30% by weight, and the fiber selected from wood pulp made of conifers and hardwoods is 65 to 5% by weight. When the linen is less than 5% by weight, the fluff of the polyester is conspicuous, and when it exceeds 30% by weight, the waist at the time of construction is excessive and sticking becomes difficult.
本発明における発泡樹脂層としては、ポリ塩化ビニル樹脂、水性エマルジョン樹脂、ポリオレフィン系樹脂を用いる。これらは、主成分たる各樹脂に、発泡剤、隠蔽剤、充填剤や、ポリ塩化ビニル樹脂の場合は可塑剤などを配合して用いることができる。 As the foamed resin layer in the present invention, a polyvinyl chloride resin, an aqueous emulsion resin, or a polyolefin resin is used. These can be used by blending each resin as a main component with a foaming agent, a concealing agent, a filler, or a plasticizer in the case of a polyvinyl chloride resin.
基材シートの表面に発泡樹脂層を設ける方法としては、発泡ポリ塩化ビニル樹脂の場合、ペーストレジンを用いる際はコーティング方式、ストレートレジンを用いる際はカレンダー方式または押し出し方式で可能である。 As a method of providing a foamed resin layer on the surface of the base sheet, in the case of a foamed polyvinyl chloride resin, a coating method can be used when a paste resin is used, and a calendar method or an extrusion method can be used when a straight resin is used.
