Description
本本発明は、住宅等の壁や天井用の内装材として貼られる壁紙に関するものであり、詳しくは汚れ防止性および施工性に優れた壁紙に関するものである。 The present invention relates to wallpaper applied as an interior material for a wall or ceiling of a house or the like, and more particularly to a wallpaper excellent in antifouling properties and workability.
従来、塩化ビニル樹脂からなる化粧層の表面に、エチレンと酢酸ビニルのランダム共重合体をケン化して得られる結晶性ポリマー（以下ＥＶＯＨ樹脂）からなるフィルムを表面被覆層として積層した汚れ防止壁紙が提案されている（例えば特許文献１参照。）。しかしながら、この汚れ防止壁紙は、壁紙の施工で使用するでん粉系接着剤が表面ＥＶＯＨ樹脂のジョイント部分等に残り、カビが発生したり、接着剤が分解して変色するなどの不具合が発生することもあった。また、オレフィン系樹脂ないしアクリル系樹脂を主体とする発泡層の表面被覆層として非ハロゲン系樹脂を加熱押出しにより積層し、且つカールを抑制する為に裏打材層の裏面に非ハロゲン系樹脂を被覆した耐汚染性壁装シートが提案されている（例えば特許文献２参照。）。この壁装シートは、エンボス絞への追従性を考慮した樹脂を用いているため、微細な絞形状が表現できるが、微細なエンボス部分の表面張力が見掛け上増大するためでん粉系接着剤が谷部に残留し汚染する場合があった。又、カールも発生しないが、製品の腰が強く扱いにくく下地への追従性が悪いことに加え、でん粉系接着剤が裏打材繊維に絡まず且つ接着剤がはじきやすいため接着力が極端に低下するという欠点もあった。 Conventionally, an antifouling wallpaper in which a film made of a crystalline polymer (hereinafter referred to as EVOH resin) obtained by saponifying a random copolymer of ethylene and vinyl acetate is laminated as a surface coating layer on the surface of a decorative layer made of a vinyl chloride resin. It has been proposed (see, for example, Patent Document 1). However, with this anti-stain wallpaper, the starch-based adhesive used in the construction of the wallpaper remains on the joint portion of the surface EVOH resin, etc., causing problems such as mold generation and discoloration due to decomposition of the adhesive. There was also. Also, a non-halogen resin is laminated by heat extrusion as a surface coating layer of a foam layer mainly composed of an olefin resin or an acrylic resin, and the back surface of the backing material layer is coated with a non-halogen resin to suppress curling. An antifouling wall covering sheet has been proposed (see, for example, Patent Document 2). Since this wall-mounted sheet uses a resin that takes into account the ability to follow the embossing restriction, a fine drawing shape can be expressed, but the surface tension of the fine embossed part increases apparently, and the starch-based adhesive is In some cases, it remained in the area and was contaminated. In addition, curling does not occur, but the product's stiffness is difficult to handle and the followability to the substrate is poor. In addition, the starch adhesive does not get entangled with the backing fiber and the adhesive is easy to repel, resulting in an extremely low adhesive strength. There was also the fault of doing.
本発明の目的は、上記課題を解消し、でん粉系接着剤の付着汚染が抑えられると共に、裏打材裏面への被覆層が無くてもカールが少なく、柔軟性があり下地追従性に優れた汚れ防止壁紙を提供することにある。 The object of the present invention is to eliminate the above-mentioned problems, suppress the adhesion contamination of the starch-based adhesive, and have little curl even if there is no coating layer on the back of the backing material. It is to provide prevention wallpaper.
本発明は裏打材上に化粧樹脂層、表面張力が４０ｍＮ／ｍ以下であってポリエチレン、ポリプロピレン、ポリブテン、ポリスチレン、ポリブタジエン、ポリイソプレン、ポリメチルメタクリレート、メチルメタクリレート系共重合体、アクリロニトリル、ポリ塩化ビニル、ポリエステル系樹脂から選ばれる１種以上の樹脂を樹脂成分とする表面樹脂被覆層を順次備える壁紙であることを特徴とし、さらに、裏打材の横方向の水中伸度を１．３％以下とし、且つ裏打材のサイズ度を７０秒以下とすることを特徴とする。
また本発明の壁紙は、積層後の表面樹脂被覆層の表面張力が４０ｍＮ／ｍ以下であることを特徴とし、さらにまた表面樹脂被覆層にエンボスを付与し、エンボス後の表面樹脂被覆層の表面張力が４０ｍＮ／ｍ以下であることを特徴とする。
そして、本発明の壁紙をでん粉系接着剤で壁下地に貼りつける工程と、貼りつけられた壁紙に付着したでん粉系接着剤をふき取る工程を有する、壁紙の施工方法であり、またその貼りつけられた壁紙に付着したでん粉系接着剤をふき取る手段を有する、壁紙施工におけるでん粉系接着剤の除去方法である。
The present invention is a decorative resin layer on a backing material, having a surface tension of 40 mN / m or less, polyethylene, polypropylene, polybutene, polystyrene, polybutadiene, polyisoprene, polymethyl methacrylate, methyl methacrylate copolymer, acrylonitrile, polyvinyl chloride The wallpaper is provided with a surface resin coating layer comprising one or more resins selected from polyester resins as a resin component, and the lateral underwater elongation of the backing material is 1.3% or less. and the size of the backing, wherein the a child less than 70 seconds.
The wallpaper of the present invention is characterized in that the surface tension of the surface resin coating layer after lamination is 40 mN / m or less, and further, embossing is given to the surface resin coating layer, and the surface of the surface resin coating layer after embossing The tension is 40 mN / m or less.
And it is the construction method of wallpaper which has the process of sticking the wallpaper of the present invention to the wall base with the starch-based adhesive, and the process of wiping off the starch-based adhesive adhered to the pasted wallpaper. This is a method for removing a starch-based adhesive in wallpaper construction, which has means for wiping off the starch-based adhesive attached to the wallpaper.
表面樹脂被覆層の表面張力を４０ｍＮ／ｍ以下とすることにより、汚れ防止性に優れた壁紙とし、裏打材の横方向の水中伸度を１．３％以下とし、且つ裏打材のサイズ度を７０秒以下とすることにより、カール性、柔軟性、下地追従性等の施工性に優れた汚れ防止壁紙を提供することが可能となる。そして、本発明のような施工方法、でん粉系接着剤の除去方法を用いることにより、壁紙表面に付着したでん粉系接着剤を僅かな水洗浄で除去することが可能となる。 By setting the surface tension of the surface resin coating layer to 40 mN / m or less, the wallpaper has excellent antifouling properties, the lateral underwater elongation of the backing material is 1.3% or less, and the backing material has a sizing degree. By setting it to 70 seconds or less, it becomes possible to provide a stain-preventing wallpaper having excellent workability such as curling property, flexibility, and background followability. And it becomes possible by using the construction method like this invention and the removal method of a starch-type adhesive agent to remove the starch-type adhesive agent adhering to the wallpaper surface by slight water washing | cleaning.
本発明の汚れ防止壁紙は、少なくとも表面樹脂被覆層、化粧樹脂層、裏打材からなり、その他の層を積層してもよい。壁紙としては通常、厚みが０．１〜２．０ｍｍの範囲のものが使用される。 The antifouling wallpaper of the present invention comprises at least a surface resin coating layer, a decorative resin layer, and a backing material, and other layers may be laminated. A wallpaper having a thickness in the range of 0.1 to 2.0 mm is usually used.
本発明の汚れ防止壁紙に用いられる表面樹脂被覆層は、表面張力が４０ｍＮ／ｍ以下、好ましくは３５ｍＮ／ｍ以下の樹脂が使用できる。また表面樹脂被覆層を多層にしてもよく、その場合は最上面に用いられている樹脂の表面張力が４０ｍＮ／ｍ以下であることが好ましい。表面張力の測定方法は、固体表面の表面張力は直接的に測定できない為、ＪＩＳ Ｋ６７６８ ポリエチレン及びポリプロピレンフィルムのぬれ試験方法に準じ、予め表面張力が判っている標準液を用いて測定する。その標準液が濡れた時の液の表面張力値を表面張力とした。
表面張力が４０ｍＮ／ｍ以下の樹脂としては、中密度ポリエチレン、高密度ポリエチレン、ポリプロピレン、ポリブテン、ポリスチレン、ポリブタジエン、ポリイソプレン、ポリメチルメタクリレート、メチルメタクリレート系共重合体、アクリロニトリル、ポリ塩化ビニル、ポリエステル系樹脂、フッ素系共重合体等が挙げられる。中でも汚れ防止性とエンボス絞の再現性を両立させる上でポリプロピレンが好ましい。又、この表面被覆層に使用する樹脂は１種あるいは２種以上の樹脂を混ぜ合わせても良い。表面張力を４０ｍＮ／ｍ以下にすることで壁紙表面に付着したでん粉系接着剤による汚染が抑えられる。さらに表面張力を３５ｍＮ／ｍ以下にすると、エンボス谷部への付着等が抑えられ僅かな水洗浄でも接着剤を簡単に除去できる。尚、表面張力が４０ｍＮ／ｍを超えた場合、でん粉系接着剤が表面やエンボス谷部に残留しやすくなり、カビの発生や接着剤の分解等により変色現象が発生し、外観上好ましくない。
The surface resin coating layer used in the antifouling wallpaper of the present invention can use a resin having a surface tension of 40 mN / m or less, preferably 35 mN / m or less. Further, the surface resin coating layer may be multilayered, and in that case, the surface tension of the resin used on the uppermost surface is preferably 40 mN / m or less. Since the surface tension of the solid surface cannot be directly measured, the surface tension is measured using a standard solution whose surface tension is known in advance according to the wettability test method of JIS K6768 polyethylene and polypropylene film. The surface tension value of the liquid when the standard liquid was wet was defined as the surface tension.
The resins having a surface tension of 40 mN / m or less include medium density polyethylene, high density polyethylene, polypropylene, polybutene, polystyrene, polybutadiene, polyisoprene, polymethyl methacrylate, methyl methacrylate copolymer, acrylonitrile, polyvinyl chloride, polyester series. Examples thereof include resins and fluorine-based copolymers. Among these, polypropylene is preferable in order to achieve both the antifouling property and the reproducibility of the embossed drawing. The resin used for the surface coating layer may be a mixture of one or more resins. By making the surface tension 40 mN / m or less , contamination by the starch-based adhesive adhered to the wallpaper surface can be suppressed. Further, when the surface tension is 35 mN / m or less, adhesion to the embossed valley is suppressed, and the adhesive can be easily removed even with slight water washing. When the surface tension exceeds 40 mN / m, the starch-based adhesive tends to remain on the surface and the embossed valley, and discoloration occurs due to generation of mold, decomposition of the adhesive, and the like, which is not preferable in appearance.
表面樹脂被覆層に用いられる樹脂に、添加剤としての加工助剤や艶消し剤、抗菌剤、消臭剤、ホルムアルデヒド吸着材、マイナスイオン放出材、導電材、顔料等を添加しても何ら問題はない。 Even if processing aids, matting agents, antibacterial agents, deodorants, formaldehyde adsorbents, negative ion release materials, conductive materials, pigments, etc., are added to the resin used for the surface resin coating layer There is no.
表面樹脂被覆層は、フィルム化されたフィルムを積層することや塗料として塗工することも可能である。尚、表面樹脂被覆層に用いるフィルム又は塗料の厚みは２μｍ〜２０μｍの範囲にすることが好ましい。表面樹脂被覆層が２μ以下であると、摩擦等により被覆層が破壊してしまいやすく汚れ防止ができなくなり、２０μｍ以上であると、壁紙としての剛性が強くなりすぎて、施工性が悪くなる。 The surface resin coating layer can be laminated as a film or applied as a paint. In addition, it is preferable to make the thickness of the film or coating material used for a surface resin coating layer into the range of 2 micrometers-20 micrometers. If the surface resin coating layer is 2 μm or less, the coating layer is likely to be damaged due to friction or the like, and it becomes impossible to prevent stains.
表面樹脂被覆層と化粧樹脂層との接着については、熱融着でも接着剤を用いてもよいが、特に熱融着性を付与することが、エンボス模様の再現性を高めると共に低コストでラミネートする事が可能となる。上記接着強度を増すために、表面樹脂被覆層と化粧樹脂層のどちらか一方或いは両方にコロナ処理、プライマー処理を施すことが好ましい。又、表面樹脂被覆層に極性ポリマーを導入してもコロナ処理、プライマー処理と同様の効果が得られ、接着強度を増すことができる。但し、ラミネートをしない面の表面張力が４０ｍＮ／ｍを超えないようにすることが必要である。 For adhesion between the surface resin coating layer and the decorative resin layer, either heat fusion or an adhesive may be used. In particular, imparting heat fusion improves the reproducibility of the embossed pattern and laminates at low cost. It becomes possible to do. In order to increase the adhesive strength, it is preferable to perform corona treatment or primer treatment on one or both of the surface resin coating layer and the decorative resin layer. Moreover, even if a polar polymer is introduced into the surface resin coating layer, the same effects as those of the corona treatment and the primer treatment can be obtained, and the adhesive strength can be increased. However, it is necessary that the surface tension of the non-laminated surface does not exceed 40 mN / m.
上記極性ポリマーとしては、エチレン−酢酸ビニル共重合体、ポリアミド、ポリエステル、ポリメタクリル酸エステル、カルボン酸−エチレン共重合体、アイオノマー、スチレン系エラストマー、ウレタン系エラストマー、アクリルゴム、ＳＢＲ、ＮＢＲなどが挙げられる。尚、これらポリマーを表面樹脂被覆層に添加しても、表面張力を４０ｍＮ／ｍ以下に調整することは言うまでもない。 Examples of the polar polymer include ethylene-vinyl acetate copolymer, polyamide, polyester, polymethacrylic ester, carboxylic acid-ethylene copolymer, ionomer, styrene elastomer, urethane elastomer, acrylic rubber, SBR, NBR, and the like. It is done. Needless to say, even when these polymers are added to the surface resin coating layer, the surface tension is adjusted to 40 mN / m or less.
化粧樹脂層に使用できる樹脂としては、低密度ポリエチレン、直鎖状低密度ポリエチレン、エチレン−プロピレン共重合体、スチレン系共重合体、エチレン−酢酸ビニル共重合体、エチレン−アクリル酸共重合体、エチレン−メチルメタクリル酸共重合体等のポリオレフィン系樹脂、ポリ塩化ビニル、アクリル系樹脂、ポリエステル系樹脂などが使用でき、コストの点ではポリ塩化ビニルが有効であり、燃焼時の発煙性などの環境性を考慮するとオレフィン系樹脂が有効である。発泡性や加工性に応じて１種又は２種以上の組合せで使用することができる。 Examples of the resin that can be used for the decorative resin layer include low density polyethylene, linear low density polyethylene, ethylene-propylene copolymer, styrene copolymer, ethylene-vinyl acetate copolymer, ethylene-acrylic acid copolymer, Polyolefin resin such as ethylene-methyl methacrylic acid copolymer, polyvinyl chloride, acrylic resin, polyester resin, etc. can be used. Polyvinyl chloride is effective in terms of cost and environment such as smoke generation during combustion In view of the properties, olefin resins are effective. Depending on the foamability and processability, it can be used alone or in combination of two or more.
化粧樹脂層に用いられる添加剤としては、難燃剤、難燃助剤、滑剤、酸化防止剤、光安定剤、紫外線吸収剤、発泡剤、発泡助剤、発泡セル調整剤、着色顔料、充填剤、抗菌剤、防カビ剤、帯電防止剤、導電材、消臭剤、ホルムアルデヒド吸着材、マイナスイオン放出材等が適宜使用できる。 Additives used in the decorative resin layer include flame retardants, flame retardant aids, lubricants, antioxidants, light stabilizers, UV absorbers, foaming agents, foaming aids, foam cell regulators, color pigments, fillers Antibacterial agents, antifungal agents, antistatic agents, conductive materials, deodorants, formaldehyde adsorbents, negative ion release materials and the like can be used as appropriate.
化粧樹脂層はカレンダー加工、押出加工、コーティング加工等によりシート化され裏打材上に積層される。 The decorative resin layer is formed into a sheet by calendering, extrusion, coating or the like and laminated on the backing material.
裏打材としては、普通パルプ紙、難燃パルプ紙、炭酸カルシウム紙、水酸化アルミニウム紙、アクリルやポリエステルなどの繊維を混ぜた紙などの壁紙用裏打材が使用可能であり、裏打材の横方向の水中伸度を１．３％以下、特に好ましくは１．０％以下に、さらに裏打材のサイズ度が７０秒以下、特に好ましくは４０秒以下に抑制することで、表面樹脂被覆層との横方向への伸びの差が小さくなると同時に裏打材の剛性が弱くなり、内反りカールを抑えることができる。尚、水中伸度が小さいほどカールは少なくなるが、サイズ度が７０秒より大きい場合は接着剤塗布後の裏打材の剛性が強いため水中伸度が小さい場合においても内反りカールが発生してしまう。サイズ度が７０秒以下で水中伸度が１．３％以上の場合は、裏打材の剛性は小さくなるものの伸び率の差が大きすぎてしまい内反りカールは改善できない。以上の如く、水中伸度およびサイズ度を適性にすることが内反りカールを改善できる手段である。
水中伸度の測定方法は、ＪＡＰＡＮ ＴＡＰＰＩ 紙パルプ試験方法Ｎｏ．２７の紙及び板紙―水中伸度試験方法のＡ法に準じ、２５０ｍｍ×２５０ｍｍの試験片を水中に１５分間浸漬したのち、水中から取り出し、余分の水分を吸取紙でとったのち寸法を測定した。
水中伸度（％）＝（Ｌ'−Ｌ）／Ｌ ＊ １００
Ｌ ：最初の長さ（ｍｍ）
Ｌ' ：浸漬後の長さ（ｍｍ）
サイズ度の測定方法はＪＩＳ Ｐ８１２２ 紙のステキヒト・サイズ度試験方法に準じ、四周を折った５０ｃｍ角の試験片を試薬上に浮かべて試薬が３点染み出す時間（秒）をサイズ度とした。
As the backing material, wallpaper backing materials such as plain pulp paper, flame retardant pulp paper, calcium carbonate paper, aluminum hydroxide paper, paper mixed with fibers such as acrylic and polyester can be used, and the lateral direction of the backing material By suppressing the elongation in water to 1.3% or less, particularly preferably 1.0% or less, and the sizing of the backing material to 70 seconds or less, particularly preferably 40 seconds or less, At the same time as the difference in the elongation in the lateral direction becomes small, the rigidity of the backing material becomes weak, and it is possible to suppress inward curling. The smaller the underwater elongation is, the less curl is. However, when the sizing degree is longer than 70 seconds, the backing material after application of the adhesive has a strong rigidity, so that even when the underwater elongation is small, inward curling occurs. End up. When the sizing degree is 70 seconds or less and the underwater elongation is 1.3% or more, the rigidity of the backing material is reduced, but the difference in elongation is too large, and the inner curvature curl cannot be improved. As described above, making the underwater elongation and sizing suitable is a means for improving the inner curvature curl.
The measuring method of the elongation in water is JAPAN TAPPI paper pulp test method no. In accordance with Method A of 27 paper and paperboard-water elongation test method, a 250 mm × 250 mm test piece was immersed in water for 15 minutes, then removed from the water, and excess moisture was taken with a blotting paper and the dimensions were measured. .
Elongation in water (%) = (L′−L) / L * 100
L: Initial length (mm)
L ′: Length after immersion (mm)
The sizing degree was measured in accordance with the JIS P8122 paper Steechtite sizing degree test method, and a 50 cm square test piece having four rounds was floated on the reagent, and the time (second) for the reagent to ooze out was defined as the sizing degree.
壁紙としての意匠性を付与する為に、印刷絵柄層やエンボス加工を付与することもできる。印刷絵柄層については、表面被覆層の下層部に印刷することで傷による損傷を受けることがないが、表面樹脂被覆層の表面張力を損なわない限り表面樹脂被覆層にも付与することができる。 In order to impart design properties as wallpaper, a printed pattern layer or embossing can also be imparted. The printed pattern layer is not damaged by being scratched by printing on the lower layer portion of the surface coating layer, but can also be applied to the surface resin coating layer as long as the surface tension of the surface resin coating layer is not impaired.
