Abstract
Description
【０００１】
【発明の属する技術分野】
本発明は、例えばリフォームなどで内装制限が必要な際の壁紙施工法に関するものである。
【０００２】
【従来の技術】
従来、壁紙を張り替える際、既存の壁紙化粧層を剥離し、壁紙裏打ち紙が残った状態で新規の壁紙を施工している。張り替えの際、当該壁紙は通常施工後５年〜１０年程度経過しており、その間、壁紙、接着剤、下地基材の劣化は免れず、剥離の際、壁紙化粧層が均一に剥離できえなかったり、あるいは裏打ち紙が下地基材に完全に接着していない場合が有った。
【０００３】
そのため新規の壁紙施工の際、事前に下地に不陸がある場合、パテ処理等で平滑にしたり、接着不良がある場合、裏打ち紙を予め壁紙施工前に剥離する必要が有った。
【０００４】
また、張り替えの際、既存の壁紙を剥離せず、一旦下張り紙を施工し、完全に壁紙施工下地を作った後、新規の壁紙を施工する工法も開発されている（例えば、特許文献１参照）。更に、下貼り紙に揮発性物質用吸着剤を含ませてホルムアルデヒド等を低減させるものも提案されている（例えば、特許文献２参照）。
【０００５】
一方、建築基準法等では、火災の際のフラッシュオーバーを防いだり、遅らせたりするために、室内の天井・壁などの内装材に不燃・準不燃の防火材料を使用するように義務づけている。これを内装制限の指定と呼ぶ。

【特許文献２】
特開２００２−２３５４１７号公報
【０００７】
【発明が解決しようとする課題】
しかしながら、張り替えの際、既存の壁紙を剥離せず、一旦下張り紙を施工し、完全に壁紙施工下地を作った後、新規の壁紙を施工する工法では、構造上は下地基材→既存壁紙用接着剤→既存の壁紙→下張り紙専用接着剤→下張り紙一新規壁紙用接着剤→新規壁紙の多層構造になっている。
【０００８】
それぞれの材料には有機分があるため、燃焼させた際の発熱量が多く、内装制限の必要な施工現場での適用は基本的に不可能であった。
【０００９】
本発明は、上記課題を解決させるためになされたものであり、その目的は張り替えの際、既存の壁紙を剥離する必要が無く、しかも新規の壁紙施工後も内装制限に適用できる壁紙施工法を得ることを目的とする。
【００１０】
【課題を解決するための手段】
請求項１に記載された発明に係る壁紙施工法は、壁紙を内装壁面に貼着するに際して、不燃性下張り紙を前記内装壁面の全面または一部に予め貼着することを特微とするものである。
【００１１】
請求項２に記載された発明に係る壁紙施工法は、請求項１に記載の不燃性下張り紙として、パルプ繊維、硝子繊維、膨張性黒鉛の何れか１つ以上を、合成樹脂系エマルジョン又は／及び水溶性樹脂の結合材（バインダー）で結着したシートを用いることを特徴とするものである。
【００１２】
請求項３に記載された発明に係る壁紙施工法は、請求項２に記載の合成樹脂エマルジョンとしてＳＢＲラテックスを用い、水溶性樹脂として水溶性ビニロンを用いることを特徴とするものである。
【００１３】
請求項４に記載された発明に係る壁紙施工法は、請求項３に記載のＳＢＲラテックスと水溶性ビニロンとの混合比率を８０／２０〜９０／１０ｗｔ％として用いることを特徴とするものである。
【００１４】
請求項５に記載された発明に係る壁紙施工法は、請求項１〜４の何れか１項に記載の不燃性下貼り紙の構成成分に含まれる有機分量を６０〜８０ｇ／ｍ２ 、膨張性黒鉛量を６０〜７０ｇ／ｍ２ とすることを特徴とするものである。
【００１５】
【発明の実施の形態】
本発明においては、壁紙を内装壁面に貼着するに際して、不燃性下張り紙を前記内装壁面の全面または一部に予め貼着するものであるため、新規の壁紙施工後も内装制限に適用できる壁紙施工法を得ることができる。また、リフォームの内装施工の場合でも、新たな下地壁を施工することなく、リフォーム前の既存の内装壁面上に不燃性下貼り紙を貼着することにより、通常の壁紙の貼着に沿って貼着作業を行うことができる。尚、内装制限が許されるのであれば通常の壁紙でもまた通常の澱粉系接着剤でも使用可能である。
【００１６】
本発明の不燃性下貼り紙としては、不燃性繊維同士を結合材で結着させたシートや、より柔軟性を持たせるため不燃性繊維をパルプ繊維等の天然繊維と複合させて結合材で結着させて不燃性としたシートが挙げられる。具体的には、パルプ繊維、硝子繊維、膨張性黒鉛の何れか１つ以上を、合成樹脂系エマルジョン又は／及び水溶性樹脂の結合材で結着したシートが挙げられる。
【００１７】
本発明での結着剤としては、不燃性繊維同士又は天然繊維と複合させた繊維同士をより強固に結着するとともに内装壁面に貼着させるために柔軟性を持たせなければならない。よって、本発明では、下貼り紙の結合材（バインダー）として、合成樹脂系エマルジョン又は／及び水溶性樹脂を用いる。
【００１８】
合成樹脂系エマルジョンとしては、例えば、酢ビ型接着剤、酢ビ−アクリル共重合型接着剤、エチレン−酢ビ共重合型接着剤、酢ビ−ベオバ共重合型接着剤、水性系ウレタン型接着剤、水性系エポキシ型接着剤、アクリル型接着剤、アクリル−スチレン共重合型接着剤等が挙げられるが、より好ましくは、合成樹脂エマルジョンとしてＳＢＲラテックスを用いる。また、水溶性樹脂としては、ポリビニルアルコール、メチルセルロース、ヒドロキシプロピルセルロース、カルボキシメチルセルロース、ポリアクリル酸ソーダ、デキストリン、α化澱粉、ポリビニルピロリドン等が挙げられるが、より具体的には、水溶性樹脂として水溶性ビニロンを用いる。
【００１９】
ＳＢＲラテックスと水溶性ビニロンとは個別に用いても良いが、より好ましくはＳＢＲラテックスと水溶性ビニロンとを混合して用いることにより、より強固な結合力が得られるとともに柔軟性を有するシートが得られる。更に好ましくは、ＳＢＲラテックスと水溶性ビニロンとの混合比率を８０／２０〜９０／１０ｗｔ％として用いる。
【００２０】
内装制限においては、貼着される場所や貼着される壁紙、また、貼着に用いる接着剤によって種々の制限があるが、不燃性下貼り紙の構成成分に含まれる有機分量を６０〜８０ｇ／ｍ２ 、膨張性黒鉛量を６０〜７０ｇ／ｍ２ とすることにより、強固な貼着と不燃効果が得られる。
【００２１】
【実施例】
（実施例１）
既存の壁紙面に、不燃性下張り紙を張り付け、その後、新規施工同様、通常の壁紙用接着剤にて壁紙を新規に張り付け、コーンカロリーメーターにて発熱量を測定した。なお下張り紙の構成としては、膨張性黒鉛、パルプ、無機粉体を基本べ−スにバインダーの構成成分、配合量を変化させ、それぞれ発熱量、表面強度、張り付け可能時間を測定した。なおブランク試験として、可燃性下張り紙（コアシ−ト（商品名）、ヤヨイ化学工業（株）社製）を適用した。結果を次の表１に示す。
【００２２】
【表１】
表１に示すとおり、バインダー種類にかかわらず、有機分量が多ければ、発熱量は増大した。バインダー種類として、ＳＢＲがアクリルより有機分量が多いにもかかわらず、発熱量が低く抑えることができた。またビニロンをバインダーに加えることにより、表面強度が強くなり、貼り付け可能時間も長くキープできることがわかった。
【００２４】
（実施例２）
実施例１より、バインダーをＳＢＲ／ビニロン系に固定し、膨張性黒鉛量、有機分量を変化させ、発熱量、表面強度、貼り付け可能時間を測定した。結果を次の表２に示す。
【００２５】
【表２】
表２に示すとおり、有機分量が６０〜８０ｇ／ｍ２ 、膨張性黒鉛含有量が６０〜７０ｇ／ｍ２ が、発熱量も抑えられ、しかも壁紙施工性に優れた性能を有することがわかった。またバインダー種類としては、ＳＢＲにビニロンを配合させることにより、材料強度が向上し、しかも貼り付け可能時間も長くキープできることがわかった。
【００２７】
椎定要因として、ＳＢＲ樹脂の柔軟な皮膜にピニロンの直鎖状物質を加えることにより、立体強度が上がるためだと思われる。配合比率に関しては、ＳＢＲ／ビニロン＝８０／２０〜９０／１０が効果的であると思われる。
【００２８】
【発明の効果】
本発明は以上説明した通り、目的は張り替えの際、既存の壁紙を剥離する必要が無く、しかも新規の壁紙施工後も内装制限に適用できる壁紙施工法を得ることができるという効果がある。[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a wallpaper construction method when interior decoration is required, for example, for renovation.
[0002]
[Prior art]
Conventionally, when replacing wallpaper, the existing wallpaper decorative layer is peeled off, and new wallpaper is constructed with the wallpaper backing paper remaining. When replacing the wallpaper, the wallpaper is usually about 5 to 10 years after construction, during which time the wallpaper, adhesive, and base material are inevitably degraded. In some cases, the backing paper was not completely adhered to the underlying substrate.
[0003]
Therefore, when a new wallpaper is applied, it is necessary to peel off the backing paper before applying the wallpaper in advance, if there is unevenness in the base material, if smooth, such as by putty treatment, or if there is poor adhesion.
[0004]
In addition, a method has been developed in which, when exchanging a new wallpaper, a new wallpaper is applied after the existing wallpaper is not peeled off, but the base paper is once applied, and the wallpaper base is completely formed (for example, see Patent Document 1). ). Further, a proposal has been made to reduce the formaldehyde and the like by including an adsorbent for a volatile substance in a base paper (for example, see Patent Document 2).
[0005]
On the other hand, the Building Standards Law requires that non-combustible or semi-combustible fireproof materials be used for interior materials such as indoor ceilings and walls in order to prevent or delay flashover in the event of a fire. This is called designation of interior restrictions.
[0006]
[Patent Document 1]
JP 2001-115621 A [Patent Document 2]
JP-A-2002-235417
[Problems to be solved by the invention]
However, when re-placing, existing wallpaper is not peeled off, and the new wallpaper is constructed after the base paper is completely applied and the new wallpaper is completely constructed. Adhesive → existing wallpaper → adhesive for base paper → adhesive for new paper → adhesive for new wallpaper → multilayer structure of new wallpaper.
[0008]
Since each material has an organic component, it generates a large amount of heat when it is burned, and it is basically impossible to apply it to a construction site that requires interior restrictions.
[0009]
The present invention has been made in order to solve the above-described problems, and its purpose is to eliminate the need to peel off existing wallpaper when replacing, and to apply a wallpaper construction method that can be applied to interior restrictions even after new wallpaper construction. The purpose is to get.
[0010]
[Means for Solving the Problems]
The wallpaper construction method according to the invention described in claim 1 is characterized in that, when the wallpaper is attached to the interior wall surface, a nonflammable lining paper is attached in advance to the entire or a part of the interior wall surface. It is.
[0011]
According to a second aspect of the present invention, as the non-combustible base paper according to the first aspect, at least one of pulp fiber, glass fiber, and expandable graphite is used as a synthetic resin emulsion or / And a sheet bound with a binder of a water-soluble resin.
[0012]
A wallpaper application method according to a third aspect of the present invention is characterized in that SBR latex is used as the synthetic resin emulsion according to the second aspect, and water-soluble vinylon is used as the water-soluble resin.
[0013]
The wallpaper application method according to the invention described in claim 4 is characterized in that the mixing ratio of the SBR latex described in claim 3 and water-soluble vinylon is used as 80/20 to 90/10 wt%. .
[0014]
According to a fifth aspect of the present invention, there is provided a wallpaper construction method, wherein the organic component contained in the component of the non-combustible underlay paper according to any one of the first to fourth aspects has an organic content of 60 to 80 g / m 2 , and has an intumescent property. The amount of graphite is set to 60 to 70 g / m 2 .
[0015]
BEST MODE FOR CARRYING OUT THE INVENTION
In the present invention, when sticking the wallpaper to the interior wall surface, since the non-combustible lining paper is previously attached to the entire or a part of the interior wall surface, the wallpaper can be applied to the interior restrictions even after the construction of the new wallpaper. The construction method can be obtained. In addition, even in the case of renovation interior construction, by sticking non-combustible underlay paper on the existing interior wall before renovation without constructing a new foundation wall, it can be pasted along the normal wallpaper sticking Wearing work can be performed. As long as interior restrictions are permitted, ordinary wallpaper or ordinary starch-based adhesive can be used.
[0016]
Examples of the non-combustible base paper of the present invention include a sheet in which non-combustible fibers are bound with a binder, or a composite in which non-combustible fibers are combined with natural fibers such as pulp fibers to provide more flexibility. A non-combustible sheet that is made to adhere is included. Specifically, a sheet in which at least one of pulp fiber, glass fiber, and expandable graphite is bound with a binder of a synthetic resin emulsion or / and a water-soluble resin is used.
[0017]
As the binder in the present invention, the non-combustible fibers or the fibers combined with the natural fibers must be more firmly bound and have flexibility to be attached to the interior wall surface. Therefore, in the present invention, a synthetic resin emulsion or / and a water-soluble resin are used as a binder of the underlaying paper.
[0018]
Examples of the synthetic resin emulsion include a vinyl acetate adhesive, a vinyl acetate-acrylic copolymer adhesive, an ethylene-vinyl acetate copolymer adhesive, a vinyl acetate-veova copolymer adhesive, and an aqueous urethane adhesive. Agents, an aqueous epoxy adhesive, an acrylic adhesive, an acrylic-styrene copolymer adhesive, and the like. More preferably, SBR latex is used as a synthetic resin emulsion. Examples of the water-soluble resin include polyvinyl alcohol, methylcellulose, hydroxypropylcellulose, carboxymethylcellulose, sodium polyacrylate, dextrin, pregelatinized starch, and polyvinylpyrrolidone. Use vinylon.
[0019]
Although the SBR latex and the water-soluble vinylon may be used individually, more preferably, a mixture of the SBR latex and the water-soluble vinylon is used to obtain a sheet having a stronger bonding force and flexibility. Can be More preferably, the mixing ratio between the SBR latex and the water-soluble vinylon is set to 80/20 to 90/10 wt%.
[0020]
In the interior restrictions, there are various restrictions depending on the place to be pasted, the wallpaper to be pasted, and the adhesive used for the pasting. m 2, by the expandable graphite amount as 60~70g / m 2, firm sticking and incombustible effect is obtained.
[0021]
【Example】
(Example 1)
Non-combustible base paper was pasted on the existing wallpaper surface, and then, similarly to the new construction, the wallpaper was newly pasted with a normal wallpaper adhesive, and the calorific value was measured with a cone calorimeter. With respect to the composition of the subbing paper, the amount of heat generation, surface strength, and possible pasting time were measured by changing the components and the amount of the binder based on expandable graphite, pulp and inorganic powder as a basic base. As a blank test, flammable base paper (core sheet (trade name), manufactured by Yayoi Chemical Industry Co., Ltd.) was applied. The results are shown in Table 1 below.
[0022]
[Table 1]
As shown in Table 1, regardless of the type of binder, the amount of heat generated increased as the amount of organic components increased. As the binder type, the calorific value was able to be suppressed to be low even though SBR had a larger amount of organic components than acrylic. In addition, it was found that by adding vinylon to the binder, the surface strength was increased, and the sticking time could be kept long.
[0024]
(Example 2)
From Example 1, the binder was fixed to the SBR / vinylon system, the amount of expandable graphite and the amount of organic components were changed, and the calorific value, surface strength, and sticking time were measured. The results are shown in Table 2 below.
[0025]
[Table 2]
As shown in Table 2, when the organic content was 60 to 80 g / m 2 and the expandable graphite content was 60 to 70 g / m 2 , it was found that the calorific value was suppressed and the wallpaper had excellent performance in wallpaper workability. . As for the binder type, it was found that the blending of vinylon with SBR improves the material strength and can keep the sticking time longer.
[0027]
It is considered that the reason for the determination is that the addition of a linear substance of piniron to the flexible film of the SBR resin increases the three-dimensional strength. Regarding the mixing ratio, SBR / vinylon = 80/20 to 90/10 seems to be effective.
[0028]
【The invention's effect】
As described above, the present invention has an effect that it is not necessary to peel off the existing wallpaper at the time of replacement, and it is possible to obtain a wallpaper construction method which can be applied to the interior decoration even after the new wallpaper construction.
