TECHNICAL FIELD OF THE INVENTION
The present invention relates to a floor tile construction method.
[0002]
[Prior art]
In recent years, as the disposal of waste materials has become extremely difficult, there has been a strong demand for recycling of construction waste materials. As a floor material, a carpet, a synthetic resin, or the like is used. However, any kind of floor material which is an obstacle in recycling is a hardening adhesive for the floor material such as cement or epoxy resin. These curable adhesives remain on the flooring material during recycling, and it is necessary to further remove the remaining curable adhesive.When recycling, the adhesive becomes granular when kneaded again and formed into a sheet. Remaining defective products may result. Such a problem of the remaining adhesive can be applied to an emulsion-type or solvent-type adhesive or pressure-sensitive adhesive.
[0003]
Therefore, a so-called laid type tile that does not use an adhesive has been developed. This floor tile is simply laid out on the floor surface without using an adhesive and is constructed and used for use, and it can be said that it is certainly a tile suitable for recycling.
However, since it is not attached to the floor substrate with an adhesive, at the start of construction, the floor tiles are likely to deviate from the reference line, resulting in poor finish, etc. It has been found that problems such as warping and formation of joints occur.
In particular, when installing floor tiles on double floors, apply an adhesive (generally called a non-slip agent) with low adhesive strength partially to the back of all tiles. Has also been done.
[0004]
[Problems to be solved by the invention]
The object of the present invention is to use a tape or a net-like material with an adhesive, while substantially ensuring the usefulness in the recycling of the floor tiles, and at the start of construction, the floor tiles are easily displaced from the reference line, and the finish is finished. It is an object of the present invention to provide a method of constructing a floor tile that can solve problems such as failure and problems in use such as formation of joints when used for a long time.
[0005]
[Means for Solving the Problems]
A first aspect of the present invention is to apply a pressure-sensitive adhesive to both surfaces having a predetermined width in advance at a position where a floor tile to be arranged along a reference line drawn on a floor substrate can be fixed at the time of construction of a floor tile. Fixing the tape or net-like material, and then laying and fixing the floor tile on the tape or net-like material, and laying the other portion of the floor tile by laying the floor tile. About the method.
A second aspect of the present invention is to fix a floor tile to which a tape or a net-like material to which a pressure-sensitive adhesive has been applied in advance is adhered to the back surface of the floor tile along a reference line drawn on the floor foundation during construction of the floor tile. Next, the present invention relates to a floor tile construction method, in which floor tiles in other portions are laid by laying.
A third aspect of the present invention is the floor tile according to claim 1 or 2, wherein the adhesive applied to both surfaces of the tape or the net-like material has an adhesive strength on the floor substrate side larger than that on the floor tile side. Construction method.
[0006]
In addition, the reference line is the reference when starting to lay the floor tile when the floor tile is arranged along the center line of the room and the floor tile shifted from the center line to adjust the surplus dimension near the wall This is a line that is usually used in floor tile construction.
The laying floor tile usually comprises a surface finishing layer and a backing layer, and the surface finishing layer may be made of a synthetic resin or carpet. There is no particular limitation as long as it is used as a surface layer of a normal floor finishing material. The synthetic resin sheet may have a transparent layer on the front surface or a foam layer on the back surface.
Examples of the carpet surface finishing layer include a carpet raw sheet in which a fibrous pile is planted in a base cloth, or a backing layer of a synthetic resin layer or a backing layer.
The backing layer usually comprises a natural or synthetic rubber layer or a synthetic resin layer.
The size of the tile is 30 to 100 cm square, preferably 40 to 60 cm square, and the thickness is 2 to 12 mm, preferably 4 to 8 mm. However, these numerical values do not limit the present invention at all.
[0007]
The net-like material is formed from synthetic fibers such as glass fiber, polyester, acrylic resin, and polyamide, and is, for example, a plain woven fabric having an interval of about 3 mm.
As the double-sided pressure-sensitive adhesive tape, a tape having a pressure-sensitive adhesive layer on both sides, such as kraft paper, cellophane, or a synthetic resin film, is used.
As the adhesive, rubber-based, urethane-based, acrylic-based, silicone-based viscoelastic polymers, if necessary, rosin-based, tackifying resins such as petroleum resins, softeners, fillers, antioxidants, A cross-linking agent is compounded, and it is compounded in consideration of tack, adhesive strength, and holding power, which are said to be three elements of the adhesive.
As the viscoelastic polymer, for example, a three-dimensional crosslinked polymer of a polyfunctional polyisocyanate compound and a poly (oxyalkylene) glycol having a molecular weight of 500 to 8,000 (alkylene has 2 to 4 carbon atoms) is used as a main component. There is something.
As a method of adhering the adhesive to the net-like material, a glass fiber, polyester, acrylic, an organic solvent solution or an emulsion composed of an adhesive composition containing a viscoelastic polymer such as rubber, urethane, acrylic, or silicone is used. A net-like material formed from a synthetic fiber such as a resin or polyamide can be dipped and dried, or the organic solvent solution or emulsion can be applied to the net-like material with a brush. These adhesives may be uniformly attached to the entire surface of the net-like material, or may be attached to a part of the net-like mesh.
In adhering the pressure-sensitive adhesive to both surfaces of the sheet or the net-like material, it is preferable that the pressure-sensitive adhesive applied to both surfaces of the tape or the net-like material has a higher adhesive strength on the floor substrate side than on the floor tile side. This is because if the adhesive strength of the adhesive on the floor tile side and that of the floor base side are about the same, if you try to peel off the floor tile, the sheet or net-like material may come off from the floor base side on the floor tile side. Occur. When this happens, you have to peel off unnecessary floor tiles. The adhesive strength of the adhesive on the floor substrate side is 1.2 times or more, preferably 1.5 times or more, and more preferably 2 times or more the adhesive strength of the floor tile side adhesive.
