Abstract
Description
本発明は、表面特性（表面強度、耐汚染性）と施工性に優れた積層壁紙およびその製造方法に関するものである。 The present invention relates to a laminated wallpaper excellent in surface characteristics (surface strength, stain resistance) and workability, and a method for producing the same.
従来、パルプ等からなる紙質基材から構成された壁紙は、安価であるが、汚れやすく、表面強度が低いといった欠点があった。壁紙の耐汚染性と表面強度を改善するために、紙質基材にエチレン酢酸ビニル共重合体フィルムを貼り合わせた、積層壁紙が広く用いられてきた。 Conventionally, wallpaper composed of a paper-based substrate made of pulp or the like is inexpensive, but has a drawback of being easily soiled and having low surface strength. In order to improve the stain resistance and surface strength of wallpaper, laminated wallpaper in which an ethylene vinyl acetate copolymer film is bonded to a paper base has been widely used.
しかしながら、エチレン酢酸ビニル共重合体フィルムを貼り合わせた積層壁紙は、汚れが付きにくく、汚れが落ちやすいといった耐汚染性に優れるが、製造工程での貼り合わせスピードが遅いため生産性が低く、商品特性としてカールしやすいため、施工性が低いといった欠点があった。 However, laminated wallpaper with an ethylene vinyl acetate copolymer film attached is excellent in stain resistance such that it is difficult to get dirty and easy to remove, but the productivity is low due to slow bonding speed in the manufacturing process. Since it is easy to curl as a characteristic, there was a drawback that workability was low.
本発明は、上述したような従来の積層壁紙の問題点を解決するためになされたものであり、本発明が解決しようとする課題は、表面強度に優れ、汚れが付きにくく、汚れが落ちやすいといった表面特性と施工性に優れた積層壁紙とその製造方法を提供することにある。 The present invention has been made to solve the problems of the conventional laminated wallpaper as described above, and the problems to be solved by the present invention are excellent in surface strength, difficult to get dirty, and easy to remove. It is providing the laminated wallpaper excellent in surface characteristics and workability, and its manufacturing method.
上記課題を解決すべく鋭意努力を重ねた結果、発泡塩化ビニル樹脂層のうえにウレタン樹脂層を設ければよいことを見出し、本発明を完成するに至った。 As a result of intensive efforts to solve the above problems, it has been found that a urethane resin layer may be provided on the foamed vinyl chloride resin layer, and the present invention has been completed.

以下本発明の実施の形態につき説明する。図１は、本発明の積層壁紙の断面模式図である。図１において、１は紙質基材を、２は発泡塩化ビニル樹脂層を、３は水性ウレタン樹脂層を表す。 Hereinafter, embodiments of the present invention will be described. FIG. 1 is a schematic cross-sectional view of the laminated wallpaper of the present invention. In FIG. 1, 1 represents a paper-based substrate, 2 represents a foamed vinyl chloride resin layer, and 3 represents an aqueous urethane resin layer.
以下、本発明の構成要件を説明する。 Hereinafter, the configuration requirements of the present invention will be described.
本発明における紙質基材としては、特に限定されず、従来の壁紙裏打紙として知られているものが使用できる。例えば普通紙（木材セルロース成分集合体）などが挙げられる。紙質基材の坪量は特に限定的でないが、好ましくは、６０ｇ〜１２０ｇ／ｍ２程度である。 The paper-based substrate in the present invention is not particularly limited, and those known as conventional wallpaper backing paper can be used. Examples thereof include plain paper (wood cellulose component aggregate). The basis weight of the paper-based substrate is not particularly limited, but is preferably about 60 to 120 g / m 2 .
紙質基材の上に、発泡塩化ビニル樹脂層を形成するには、熱分解型発泡剤を含む軟質塩化ビニル樹脂組成物をカレンダーロールによりシート状に加熱成形して、紙質基材上に熱分解型発泡剤を含む軟質塩化ビニル樹脂組成物を貼り合わせるか、熱分解型発泡剤を含むペースト状塩化ビニル樹脂組成物をコーターでコーティングすればよい。 In order to form a foamed vinyl chloride resin layer on a paper-based substrate, a soft vinyl chloride resin composition containing a thermal decomposable foaming agent is thermoformed into a sheet shape with a calender roll and then thermally decomposed onto the paper-based substrate. A soft vinyl chloride resin composition containing a mold foaming agent may be bonded together, or a pasty vinyl chloride resin composition containing a pyrolytic foaming agent may be coated with a coater.
カレンダーロールによる方法の場合、カレンダー加工は熱分解型発泡剤が分解発泡する温度以下で行い、後述するように、水性ウレタン樹脂組成物を塗布し加熱乾燥した後、熱分解型発泡剤が発泡する温度以上に加熱し、紙質基材のうえに発泡塩化ビニル樹脂層を形成する。カレンダー加工温度は配合する熱分解型発泡剤の種類により異なるが、例えば１２０℃〜１５０℃の範囲で行えばよい。 In the case of the method using a calender roll, calendering is performed at a temperature below the temperature at which the pyrolytic foaming agent decomposes and foams, and as described later, the aqueous urethane resin composition is applied and dried by heating, and then the pyrolytic foaming agent foams. It heats more than temperature and forms a foaming vinyl chloride resin layer on a paper-like base material. Although the calendering temperature varies depending on the type of the pyrolytic foaming agent to be blended, for example, it may be performed in a range of 120 ° C to 150 ° C.
コーティング法の場合は、コーティング液（ペースト状塩化ビニル樹脂組成物）の塗布物のセット温度は熱分解型発泡剤の分解発泡する温度以下で行い、後述するように水性ウレタン樹脂組成物を塗布し加熱乾燥させた後、熱分解型発泡剤が発泡する温度以上に加熱し、紙質基材上に発泡塩化ビニル樹脂層を形成させる。 In the case of the coating method, the coating temperature of the coating liquid (paste-form vinyl chloride resin composition) is set below the temperature at which the pyrolytic foaming agent decomposes and foams, and the aqueous urethane resin composition is applied as described later. After heat-drying, it heats more than the temperature which a pyrolysis-type foaming agent foams, and forms a foaming vinyl chloride resin layer on a paper-like base material.
熱分解型発泡剤を含む塩化ビニル樹脂層の厚みは、限定的ではないが０．１〜０．３ｍｍの間で適宜選択すればよい。 The thickness of the vinyl chloride resin layer containing the pyrolytic foaming agent is not limited, but may be appropriately selected between 0.1 and 0.3 mm.
熱分解型発泡剤を含む塩化ビニル樹脂組成物としては、塩化ビニル樹脂、安定剤、滑剤等の助剤、熱分解型発泡剤、着色剤、充填剤、可塑剤からなる組成物を挙げることができる。 Examples of the vinyl chloride resin composition containing a pyrolytic foaming agent include a composition comprising an auxiliary agent such as a vinyl chloride resin, a stabilizer, a lubricant, a pyrolytic foaming agent, a colorant, a filler, and a plasticizer. it can.

本発明で用いる安定剤、助剤、着色剤、充填剤、よび可塑剤は、塩化ビニル樹脂の加工に常用されている成分であればその種類と配合量は特に限定されない。希釈剤とは、コーティング液の粘度調整のために用い、通常粘度１５±５dPasになるように配合する者であり、ノルマルパラフィンを挙げることができる。 If the stabilizer, auxiliary agent, coloring agent, filler, and plasticizer used in the present invention are components that are commonly used in the processing of vinyl chloride resins, the types and blending amounts thereof are not particularly limited. The diluent is a person who is used for adjusting the viscosity of the coating liquid and is usually blended so as to have a viscosity of 15 ± 5 dPas, and examples thereof include normal paraffin.
発泡樹脂層に含まれる発泡剤として、熱分解型発泡剤が好ましい。例えば、アゾジカルボンアミドが挙げられる。 As the foaming agent contained in the foamed resin layer, a pyrolytic foaming agent is preferable. An example is azodicarbonamide.
紙質基材上に熱分解型発泡剤を含む塩化ビニル樹脂層を形成した後、塩化ビニル樹脂層の表面に水性ウレタン樹脂組成物を塗布する。 After forming a vinyl chloride resin layer containing a thermally decomposable foaming agent on a paper substrate, an aqueous urethane resin composition is applied to the surface of the vinyl chloride resin layer.
水性ウレタン樹脂組成物とは、ポリウレタンを乳化剤で乳化したエマルジョンや、ポリウレタンを変性して水溶性を付与した変性ポリウレタンの水溶液などを挙げられるが、ポリウレタンが水中に乳化、分散または溶解したものであればよい。 Examples of the aqueous urethane resin composition include an emulsion obtained by emulsifying polyurethane with an emulsifier, and an aqueous solution of a modified polyurethane obtained by modifying polyurethane to impart water solubility.

In particular, a method using a printing press is preferable in that the application efficiency can be improved and existing facilities can be used.
水性ウレタン樹脂は、５〜１５ｇ／ｍ２となるように塗布し、１１０℃〜１３０℃、好ましくは１２０℃で電気炉で乾燥することにより水性ウレタン樹脂層を形成させる。 A water-based urethane resin is apply | coated so that it may become 5-15 g / m < 2 >, and a water-based urethane resin layer is formed by drying with an electric furnace at 110 to 130 degreeC, Preferably it is 120 degreeC.
さらに、水性ウレタン樹脂層に水性艶消し剤を塗布し、艶消し処理をすることも好ましい。艶消し処理をすることにより、デザインの多様性に対応することが可能となる。 Further, it is also preferable to apply an aqueous matting agent to the aqueous urethane resin layer and perform matting treatment. By matte treatment, it is possible to cope with a variety of designs.
水性艶消し剤としては、例えば、塩化ビニル系重合体エマルジョン（シリカ含有）が挙げられる。 Examples of the aqueous matting agent include a vinyl chloride polymer emulsion (containing silica).
次いで、原反を熱分解型発泡剤が熱分解する温度以上に加熱して、塩化ビニル樹脂組成物に含まれた熱分解型発泡剤を分解発泡させる。熱分解型発泡剤を発泡させるには、最終加熱温度が２００〜２５０℃となるように加熱する。 Next, the raw fabric is heated to a temperature equal to or higher than the temperature at which the pyrolyzable foaming agent thermally decomposes, and the pyrolyzable foaming agent contained in the vinyl chloride resin composition is decomposed and foamed. In order to foam the pyrolytic foaming agent, the final heating temperature is heated to 200 to 250 ° C.
最後に、必要に応じて発泡原反にエンボス加工を行う。発泡した原反を再度加熱し、任意の凹凸模様が付与されたロールに押し当て加圧、賦形後、冷却すればよい。 Finally, embossing is performed on the raw foam as necessary. What is necessary is just to heat the foamed original fabric again, press against a roll provided with an arbitrary concavo-convex pattern, pressurize and shape, and then cool.
