DETAILED DESCRIPTION OF THE INVENTION
The present invention has been intensively studied on a laying tatami mat that is light but has excellent anti-slip function. As a result, the tatami floor is a combination of a synthetic resin sheet and a core made of particle board or insulation board. When a non-slip sheet made of an ethylene vinyl acetate copolymer is laminated on the back surface of a tatami structure layered with tatami mats made of artificial grass, a laying tatami mat that achieves the above problem at once is provided. It has been clarified that can be done.
In addition, in order to make a tatami mat with beautiful aesthetics and fashionability at the end of the tatami floor, the tatami floor must be in the form of an edgeless tatami covered with a tatami surface, or the side of the edge can be decorated. Has been found to be effective.
[0007]
That is, the laying tatami mat of the present invention uses a tatami mat made of artificial grass and uses a tatami floor made of a synthetic resin sheet and a core made of particle board or insulation board as a tatami floor laminated on the tatami mat. In addition, the anti-slip sheet made of ethylene vinyl acetate copolymer is laminated on the back of this tatami floor, so it has excellent anti-slip function, that is, it does not slip tightly on the floor, despite being extremely light and thin. It is possible to provide a tatami mat with excellent stability.
[0008]
Artificial grass referred to in the present invention includes, for example, polyolefin resins such as polypropylene, polyethylene, copolymers of propylene and ethylene, and mixtures thereof, polyamide resins, polyester resins, acrylic resins, mixtures thereof, and the like. Ru der those composed of a resin composition composed mainly of inorganic filler such as a thermoplastic resin and calcium carbonate and a copolymer.
[0009]
A tatami table is produced by weaving such artificial weeds as wefts, but in some cases, it can be made by changing the pitch of the warps or by a method such as jacquard weaving.
[0010]
After the tatami mat is cut to an appropriate size, a tatami floor composed of a combination of a synthetic resin sheet and a core material is laminated on the tatami mat, and a non-slip sheet is further laminated on the back surface of the tatami mat. A tatami mat is formed. In that case, an edgeless tatami obtained by folding the tatami surface at the edge of the tatami floor and covering the tatami floor can also be used.
[0011]
The synthetic resin sheet constituting the tatami floor is composed of at least one selected from an elastic resin sheet mainly made of a thermoplastic resin and a foam sheet.
[0012]
Examples of such thermoplastic resins include polyethylene, polypropylene, copolymers of propylene and ethylene and mixtures thereof, polyamides, polyesters, polyacrylonitrile, copolymers and mixtures thereof, polyurethane, polystyrene, polyvinyl chloride and Mixtures and the like can be used. As the elastic sheet, a soft solid sheet having elasticity made of such a thermoplastic resin is used.
[0013]
As the foam sheet, one having an expansion ratio of 2 to 30 times is preferably used, and a hard foam sheet such as a hard resin such as a polyolefin resin or a polystyrene resin is more preferably used. Such a foam sheet preferably has a thickness of 0.5 to 5 mm, more preferably 1 to 3 mm, and a laminate sheet having at least one layer, preferably a plurality of layers is used.
[0014]
In that case, the synthetic resin sheet whose shape is maintained by the core material is used in the present invention. That is, a laminate of a said synthetic resin sheet and the core material, for example, synthetic resin sheet / core, synthetic resin sheet / core / synthetic resin sheet, synthetic resin sheet / core / synthetic resin sheet / core / A laminate structure such as a synthetic resin sheet is used.
Such a core material, have a shape retention property, on which is excellent in rigidity and stretchability, using a Rukoto Excellent lightweight and strength, particle board, the insulation board or al one selected To do .
[0015]
In such a tatami floor, in consideration of a level difference in the flooring, a tatami mat having a taper at the edge of the tatami mat can be used. In addition to this form, by using a borderless tatami structure, it is possible to provide a laying tatami mat that is rich in aesthetics and fashion.
[0016]
An anti-slip sheet is laminated on the back surface of the tatami structure. The slip sheet over TMG, adhesion to the floor of the該畳structure is intended to ensure fixation, it is composed of d styrene vinyl acetate copolymer of the polymer having viscoelasticity .
[0017]
In the tatami mat structure of the present invention, a structure in which a nonwoven fabric sheet is laminated between a tatami mat and a tatami floor is preferably used. Of course, in order to express natural sensation, the surface may be made of cocoon instead of non-woven fabric.
[0018]
Next, the nonwoven fabric is not an indispensable component for tatami flooring, but it is usually used for providing a soft touch feeling and cushioning properties. For example, a nonwoven fabric manufacturing method such as short fiber, melt blown, spun bond, etc. Anything can be used as long as the fibers are entangled, for example, fiber scraps.
[0019]
The basis weight of the nonwoven fabric is preferably 50 to 1000 g / m ² , more preferably 100 to 800 g / m ² , particularly preferably from the viewpoint of soft touch feeling and cushioning of the tatami surface, and handling properties such as laying work. The thing of the range of 200-600 g / m < ² > is used.
[0020]
As a material constituting such a nonwoven fabric, a mixture with natural fibers can be used in addition to the above-mentioned thermoplastic resin material. Examples of such natural fibers that can be used include wool, cotton, hemp, rayon, pulp, fiber scraps, and mixtures thereof. Of course, it may be composed only of such natural fibers .
[0021]
When laminating the nonwoven fabric sheet and the tatami floor, and further the tatami floor and the tatami surface, an appropriate method such as sewing, fusing, or an adhesive can be used. For example, as the adhesive, rubber-based, epoxy-based, urethane-based, silicon-based or the like can be appropriately selected according to the material. It is also possible to heat-seal with a low-melting polymer powder or a fibrous material, or to directly heat-seal the tatami surface and the nonwoven fabric surface by heating. As such a low-melting-point polymer, a low-melting-point polymer such as a polyolefin-based resin, a copolymerized polyester, a copolymerized polyamide or the like, preferably 80 to 150 ° C., more preferably 100 to 130 ° C. can be used.
[0022]
Hereinafter, the present invention will be described with reference to the drawings. FIG. 1 is a cross-sectional view showing an example of the laying tatami mat of the present invention. The tatami floor 2 in this figure is a two-layer structure composed of a synthetic resin sheet (foamed polystyrene) A and a core material (particle board) B. A polyester fiber nonwoven fabric sheet 3 having a basis weight of 90 g / m ² is laminated on the surface of this tatami floor.
[0023]
If necessary, this tatami mat 1 has a portion that becomes a bent portion of the edge portion formed by melting the back surface by melting the surface (a groove by cutting; not shown). Can be formed. This technique is more effective when the steps of the tatami floor are used as they are. In this case, one groove is formed in each portion corresponding to the thickness of the tatami floor 2. That is, this groove functions as a crease groove.
[0024]
An anti-slip sheet 4 made of an ethylene vinyl acetate copolymer is attached to the back surface of this tatami structure (rimless tatami mat) with a neoprene rubber adhesive.
[0025]
In such laying tatami mats, for example, when the edges are stepped like ordinary tatami mats, it is beautiful to use the side of the edges decorated, and select the decoration color and design By doing so, it is possible to provide a room having an aesthetic and fashionable balance in flooring. Such decoration processing is achieved, for example, by laminating a decoration tape or a decoration sheet on the side surface of the tatami floor. Of course, a border tape can be adopted as such a decorative tape.
[0026]
The laying tatami mat of the present invention may have a normal tatami thickness, but for use as a carpet or carpet, the total thickness of the tatami structure is preferably 20 mm or less, more preferably 10 mm or less. Things may be functionally superior.
[0027]
【Example】
Example 1
100 parts of polypropylene and 60 parts of polypropylene chip containing 60% by weight of calcium carbonate were mixed with 0.3 part of azodicarbonamide and melted at 210 ° C. with an extruder, and this molten polymer was 4 m / min from the die. Discharged at a speed.
[0028]
The discharged molten polymer is foamed and introduced into a cooling water tank having a water surface 30 cm directly below the die. After the polymer temperature is cooled to the water temperature, the resulting unstretched hollow foam is guided to a heated stretching zone heated to 180 ° C. It is heated here and stretched 7 times.
[0029]
The stretched linear hollow foam is drawn down into the can and guided to the weaving process. The resulting linear hollow foam had an outer diameter of 1.25 mm, a hollow portion with a diameter of 0.5 mm, and a large number of streaky irregularities extending in the axial direction. The artificial grass thus obtained was very similar in appearance and texture to natural grass.
[0030]
Next, using a weaving machine in which the weft insertion device of the artificial weed weaving machine was changed to a single rapier mechanism, we set the artificial weeds that had been pulled down to Kens, and applied it to the weaving machine using Manila hemp as the warp . As a result, a tatami mat with a weft of 1200 mm and a basis weight of 1.8 kg / tatami was woven.
[0031]
Next, a polyester nonwoven fabric sheet having a basis weight of 80 g / m ² is partially bonded to each surface of two hard polystyrene sheets having a thickness of 4 cm and 3 mm, and laminated by using a rubber-based solvent type adhesive. Two tatami floors were formed by partially bonding an insulation board having a thickness of 2 mm with the same adhesive and laminating them on the back side.
[0032]
The two tatami floors are bonded to the nonwoven fabric lamination side with the above-mentioned woven tatami mat with a width of 1200 mm using the above-mentioned adhesive to create two types of artificial tatami mats with a width of 900 mm and a length of 1800 mm Two tatami mats were prepared by adhering a 2 mm thick ethylene vinyl acetate copolymer sheet (non-slip sheet) to the back of the insulation board with the same adhesive.
[0033]
These laying tatami mats were laid in the center between 6 tatami mats made of wooden floors and evaluated.
As a result, the one similar to a normal tatami structure with a large thickness is 1/3 or less compared to a normal natural grass tatami mat (tatami floor = wall) except that there is a step. It was very light (9.5kg / tatami mat), and it was a flooring tatami mat that was in close contact with the floor that did not slip even when external force was applied.
[0034]
On the other hand, the thin carpet type is lighter than the above (4kg / tatami), does not feel high and low, does not move or slide due to external force, is firmly attached to the floor, and the boundary is inconspicuous It was flat and beautiful flooring.
[0035]
【The invention's effect】
According to the present invention, it is possible to provide a beautiful flooring that is light and easy to perform flooring, and that is stable and aesthetically pleasing and fashionable, which is in close contact with the floor and hardly moves.
