That is, it was difficult to remove the laid tile-like fiber flooring material from the floor surface, and in some cases, the floor surface could be damaged. Furthermore, in order to fix the position again, it is necessary to use a new adhesive, adhesive, or double-sided tape, which is inconvenient to use and leads to waste.

ずれを防止することができるものである。In other words, by attaching a microporous membrane, the viscoelasticity of the microporous membrane is combined with the suction effect of the open micropores that make up the microporous membrane to improve the tile-like fiber flooring material. It can exhibit an adhesive effect when pressure-bonded to the floor surface, and can prevent the tile-like fiber flooring material from shifting.
本発明における微多孔質膜としては、ポリウレタン樹脂
、ＳＢＲ樹脂、ＮＢＲ樹脂、シリコーン樹脂などの樹脂
組成物からなるものが好ましく適用できる。As the microporous membrane in the present invention, those made of resin compositions such as polyurethane resins, SBR resins, NBR resins, and silicone resins can be preferably applied.
また、該微多孔質膜は、ゴム領域での動的弾性率（１０

ング率、モジュラスが大きくなり、硬くなり好ましくな
い。In addition, the microporous membrane has a dynamic elastic modulus (10
g1oE') is 9. It is preferable that it is 0 dyne/cffl or less. A resin having properties higher than this is undesirable because it becomes hard and has a large Young's modulus and modulus.

ましい。On the other hand, for microporous membranes, the peak temperature of dynamic loss E# is -5
0 to -10°C1 loss tangent (tan δ) peak value is 0.
It is preferably 8 or less. If this value exceeds 0.8 or less, the pore structure of the microporous membrane made using it tends to collapse due to compression, which is undesirable. . On the other hand, the peak temperature of the dynamic loss E'' is generally referred to as the glass transition point, and is preferably from -50°C to -10°C from the viewpoint of low-temperature properties.
動的損失Ｅ＃のピーク温度は低いほど良いが、耐熱性と
の関係があり、あまり低くすると必然的に耐熱性が低下
し、実用時に問題が発生する。The lower the peak temperature of the dynamic loss E#, the better, but it has a relationship with heat resistance, and if it is too low, the heat resistance will inevitably decrease, causing problems in practical use.
方、−１０°Ｃ以上になると、一般に低温硬化性が大き
くなり、好ましくない。On the other hand, if the temperature is -10°C or higher, low-temperature curability generally increases, which is not preferable.

However, it is preferable to select one having a thickness of 091 or higher or from the viewpoint of adhesion to the floor surface. Moreover, if the thickness exceeds 10.5 mm, flexibility and adhesion will be impaired, which is not preferable. The open pore area occupying the entire surface of the microporous membrane is preferably 20% or more.

に球状孔が最適である。The pores constituting the microporous membrane have a ratio of major axis (7) to minor axis (1) of 1.0 to 3.8, preferably 1. Substantially spherical pores having a circular shape ranging from 0 to 3 degrees and whose major diameter is less than 180 microns, preferably from 10 to 100 microns are most suitable.
本発明において、微多孔質膜に粘着剤を付与することは
好ましい。すなわち、粘着剤を付与することによって一
部タイル状繊維床材と床面との密着性を増す。In the present invention, it is preferable to apply an adhesive to the microporous membrane. That is, by applying an adhesive, the adhesion between a part of the tile-like fiber flooring material and the floor surface is increased.
粘着剤としては、ウレタン系粘着剤、ゴム系粘着剤、ア
クリル系粘着剤およびゴム−アクリル系併用粘着剤が好
適である。Suitable adhesives include urethane adhesives, rubber adhesives, acrylic adhesives, and rubber-acrylic combination adhesives.
本発明のタイル状繊維床材においては、前記のように、
樹脂層を２層に分けたことか一つの特徴であって、これ
によって変形しに＜＜、敷設し易いタイル状繊維床材が
得られる。In the tile-like fiber flooring of the present invention, as described above,
One of the features is that the resin layer is divided into two layers, and this makes it possible to obtain a tile-like fiber flooring material that is easy to deform and lay.
なお、タイル状繊維床材が床面にフィツトするには、適
度な重量を有することが必要である。このために、非発
泡樹脂層の重量Ｂ１と発泡樹脂層の重量Ｃ１との合計が
０．９〜３． ＣＪｋｇ／ｒｄの範囲内、好ましくは１
． ２〜２． ５ｋｇ／ｄの範囲内にあることが必要で
ある。これらの合計重量か０゜９ｋｇ／ｄより軽いとき
は、得られるタイル状繊維床材の床面に対するフィツト
性か乏しく、また、３、Ｏｋｇ／ｒｒｒより重くなると
、運搬、搬入、敷設が困難となり、かつ経済的にも不利
になる。Note that in order for the tile-like fiber flooring material to fit onto the floor surface, it needs to have an appropriate weight. For this purpose, the sum of the weight B1 of the non-foamed resin layer and the weight C1 of the foamed resin layer is 0.9 to 3. Within the range of CJkg/rd, preferably 1
．． 2-2. It is necessary to be within the range of 5 kg/d. If the total weight of these is less than 0.9 kg/d, the resulting tile-like fiber flooring material will have poor fit to the floor surface, and if it weighs more than 3.0 kg/rrr, it will be difficult to transport, carry in, and lay. , and is economically disadvantageous.
また１、タイル状繊維床材の上向きの１反り」を防止す
ためには、非発泡樹脂層の重量Ｂ１と発泡樹脂層の重量
Ｃ＋ との間に、Ｂ１／Ｃ１ ≧１． ０の関係が成立
することが必要である。Ｂ＋／Ｃが１．０より小さくな
ると、タイル状繊維床材は、自然に繊維表層に「反り」
を生ずる傾向がある。In addition, 1. In order to prevent "upward warping of tile-like fiber flooring materials," it is necessary to maintain a ratio of B1/C1 ≧1 between the weight B1 of the non-foamed resin layer and the weight C+ of the foamed resin layer. It is necessary that a relationship of 0 holds true. When B+/C is less than 1.0, the tile-like fiber flooring will naturally "warp" on the fiber surface layer.
There is a tendency to cause
このような「反り」を生ずると、タイル状繊維床材の端
縁部が床面から上にまくれ上り、走行者がこれにつまづ
く危険があり、かつ著しく美観を損う。When such "warping" occurs, the edge of the tile-like fiber floor material curls up from the floor surface, creating a danger of tripping on the tile-like fiber flooring and causing a significant loss of aesthetics.
なお、繊維表層を構成する繊維材料が立毛パイルである
場合は、立毛パイルの脱落を防止するために、その根元
部分に対し、基布との接着のための接着剤処理を施して
もよい。In addition, when the fiber material constituting the fiber surface layer is a napped pile, in order to prevent the napped pile from falling off, the root portion thereof may be treated with an adhesive for adhesion to the base fabric.
