[Industrial applications]

 TECHNICAL FIELD The present invention relates to a tatami mat, and more particularly to an improvement of a thin tatami mat that is preferably used for incorporating a tatami mat into a part of a flooring space.

[0002]

[Prior art]

 Traditional Japanese tatami mats were generally made by stacking and compressing rice straw and sewn together, attaching a tatami mat table to the tatami mat, and sewing a tatami mat made of cloth. After that, a new material tatami mat made of a composite material of natural and plastic was attached to the building material tatami floor using new materials such as insulation boards made from wood fibers and polystyrene foam foamed with polystyrene resin. Many new tatami mats are used.

[0003]

[Problems to be solved by the device]

 However, traditional tatami mats that use the straw mat floor and the grass mat mat have the drawbacks of being extremely heavy, having high water absorption, and being susceptible to discoloration due to sunburn. There is also a problem that bacteria such as house mites easily propagate.

In a new tatami mat in which a new material tatami mat is attached to the building material tatami mat, the tatami mat 12 has a foam polystyrene board 13 sandwiched by insulation boards 14 in a sandwich shape as shown in FIG. The backing sheet 15 is adhered to the back side surface. The insulation board 14 is formed by compressing wood fibers, and the backing sheet 15 is made of a synthetic resin sheet having a thickness of 0.5 mm.

The new material, tatami mat, has no discoloration, no sunburn, and no water absorption, so that it does not easily get stains or stains and has the advantage of suppressing the reproduction of house mites. On the other hand, tatami mats are light and do not lose their shape when dry, while the insulation boards used are water absorbent and flammable. Although flammability can be solved by adding a flame-retardant material, it is difficult to prevent water absorption due to the use of wood fiber as a raw material. Therefore, in the conventional new tatami mat, when water permeates the tatami mat and reaches the insulation board, the board absorbs this water and swells or is deformed such as dented. Moreover, it cannot be said that the strength is sufficient. In addition, there is a problem that warping tends to occur in a tatami having a small thickness.

When a tatami mat is partly placed on the flooring, it is inevitable that the tatami mat should be made thin. In order to achieve this thinning, a tatami mat is used instead of the insulation board. However, it is still inferior in strength, and it is still not a solution to water absorption.

Therefore, an object of the present invention is to provide an improved tatami mat that is thin, lightweight, rich in flame retardancy, and strong against water.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a tatami floor in which synthetic resin plates are bonded to the upper and lower surfaces of expanded polystyrene foam using a binder and a synthetic resin lining sheet is bonded to the back surface, plastic, natural resin, and calcium. It consists of a tatami mat woven using artificial grass and a tatami edge made of synthetic fiber cloth, and the synthetic resin plate reinforces the synthetic fiber non-woven fabric. A tatami mat used as a material, which is a flame-retardant plate-like material obtained by impregnating this non-woven fabric with a polyester resin and curing.

[0009]

[Action]

 According to the present invention, the tatami floor has improved strength by adhering synthetic resin plates to the upper and lower surfaces of expanded polystyrene foam using a binder, and is superior in flame resistance and water resistance without deformation. The tatami mat is made of artificial grass that is made of a composite of plastic and natural materials, so it retains a suitable texture and elasticity, is resistant to moisture, does not fade, and is durable. Further, the synthetic resin cloth has a quick-drying property. The tatami of the present invention manufactured by these combinations is light, thin and does not deform even if it is thin, it has flame resistance and it has excellent water resistance, so it does not discolor even if it spills water or other liquids. No, it is extremely strong against moisture such as early drying.

【Example】

 1 is a perspective view of a tatami mat according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along the section line II-II of FIG.

The tatami mat 1 of the present invention is a tatami mat suitable for a tatami mat space that is mainly disposed in a part of a flooring space of a Western-style room, and is manufactured with a thickness of 25 mm as a standard.

The tatami mat 1 of the present invention comprises a tatami mat floor 2, a tatami mat table 8, and a tatami edge 10.

As shown in FIG. 2, the tatami floor 2 has a synthetic resin board 4 adhered and fixed to the upper and lower surfaces of expanded polystyrene foam 3 using a binder 5, and a synthetic resin lining sheet 6 on the back surface of the adhesive material. Attached by 7.

The expanded polystyrene foam 3 is a lightweight, high melting point 230 ° C., water-repellent semi-rigid plate, and its reference thickness is set to 18 mm. For the binder 5, for example, Instar Bond (trademark) KC-901 manufactured by Shoei Chemical Co., Ltd. is preferably used.

The synthetic resin plate 4 is, for example, a non-woven cloth made of synthetic fiber having a high flammability temperature such as Tetron as a reinforcing material, and is a plate-like body obtained by impregnating this with a polyester resin and curing it, and having a reference thickness of 2 mm. To be done. This synthetic resin plate 4 has extremely high mechanical strength, low water absorption, a flammable temperature of 260 ° C., and flame resistance.

The lining sheet 6 is preferably a woven fabric having a thickness of 0.5 mm obtained by plain-weaving a narrow vinyl tape, but other water-repellent sheet-like body may be used.

As the paste material 7, a nonflammable and water-insoluble adhesive is used.

The tatami mat 1 is manufactured by placing the tatami mat 8 on the tatami floor 2 and arranging the tatami edges 10 at both ends in the width direction, and then sewing the four mats in the same manner as in the conventional art.

In such a tatami mat 1, the tatami mat 2 has a strength even if the thickness is thin because the foamed styrene foam 3 and the synthetic resin board 4 are integrally combined and fixed to each other through the binder 5. It has high durability, does not undergo deformation such as stretching or warping, and has excellent durability, which is light.

The tatami mat 8 is preferably a new material tatami mat woven using artificial grass, for example, Migusa (trade name) manufactured by Sekisui Mold Co., Ltd. As mentioned above, this tatami mat is made of a new composite material made of a combination of plastics and inorganic / natural materials, has moderate absorbency and slipperiness, does not cause discoloration or fading, and is free from mold. In addition, it does not easily get dirty, has a low fluffiness, low water absorption, and has an appropriate elasticity due to its resilience. However, this new composite material is non-toxic and does not generate toxic gas when burned.

Further, as the tatami mat 10, a woven fabric made of, for example, polyester fiber, which has little dirt and is rich in water repellency, is used.

A backing paper 11 for sticking prevention is attached to the back surface of the tatami 1 if necessary.

The tatami mat 1 using such a material is light and flame-retardant, and does not stretch or warp even if the thickness is thin, and is highly durable. And the most important feature of the present invention is that the water absorption is extremely low. Therefore, even if it gets wet, it can be prevented from being deformed like a conventional tatami mat and becoming unusable. If it gets dirty, it can be washed completely.

The tatami of the present invention can be easily removed and moved when it is not needed, and the storage space is small when it is stored.

The structure of the present invention can be applied not only to a thin tatami mat but also to a normal tatami mat for Japan.

[0026]

[Effect of device]

 As described above, the tatami floor of the present invention is composed of a lightweight expanded polystyrene foam sandwiched between Tetoron boards and a lining sheet adhered to the back surface, and the synthetic resin board is made of synthetic fiber non-woven fabric. A flame-retardant plate-like body cured with a polyester resin used as a reinforcing material is applied. A well-known tatami mat woven from artificial grass is used as the tatami mat, and a synthetic fiber fabric having water repellency and durability is used as the tatami mat.

In the tatami of the present invention having such a combination, since the entire tatami is lightweight, the tatami can be easily moved. Even if the tatami mat is thin, it does not warp or lose its shape and is strong in strength. Besides, it is hard to burn. Since the tatami of the present invention has no water absorption throughout the composition and high water repellency, it dries quickly even when water or other liquid spreads on the tatami. For this reason, it can be washed with water if necessary, and it has a great effect not found in conventional tatami mats, and has a wide range of applications.
