有効に使用されている。2. Description of the Related Art In recent years, tatami mats, which partially or wholly make up a tatami mat floor, are made of a thermoplastic resin foam, an insulation board, or the like.
On the other hand, the demand for tatami mats, which are thinner and lighter than before, is increasing. For example, in Japanese Patent Laid-Open No. 7-217163,
A tatami mat is disclosed that uses a tatami floor in which foamed sheets compressed in the thickness direction are laminated on both sides of a plywood board. When a veneer board is used for a tatami floor, the thickness of the entire tatami can be reduced, and since the thickness of the tatami is moderate, a suitable strength can be obtained.

優れた製造の容易な素材が求められていた。However, when cutting the veneer plate to a certain size, a saw or a sharp blade must be used, which causes a problem that the cutting process requires a little labor. Further, when the tatami mat and the tatami floor are sewn together, there is a problem that the hardness of the veneer plate adversely impairs workability. For the above reasons, there has been a demand for a material which has physical properties equal to or higher than those of the veneer plate and which is superior in cutting workability to the veneer plate and which can be easily manufactured.

The plate-like material of the present invention is preliminarily mixed with 30 to 70% by weight of a thermoplastic resin and 70 to 30% by weight of wood powder (a pine, cypress, oak etc. milled into 30 mesh and dried). Then, the mixture was charged from the hopper of the extruder, extruded from the flat mold, sandwiched between two iron rolls, and cooled to obtain a plate-shaped product having a thickness of 1 mm and a width of 1200 mm.

的であるので特に好ましい。The plate-like material may be used alone, but one or both sides of the plate-like material may be made of a thermoplastic resin in order to add heat insulating property, improve the feeling of stepping, and give a soft feeling. Foams, insulation boards, straws, paper materials and the like may be laminated using an adhesive means such as a double-sided adhesive tape or a rubber adhesive. In particular, a thermoplastic resin foam is particularly preferable because it has excellent heat insulating properties, lightweight properties, buffer properties, and is hygienic.

合わない。The plate-like material of the present invention comprises a thermoplastic resin 30-7.
It consists of a mixture of 0% by weight and 70 to 30% by weight of wood flour.
If the thermoplastic resin content is less than 30% by weight, chipping or cracking is likely to occur, which is not preferable for practical use. Conversely, if it exceeds 70% by weight, sewing is difficult and it is not preferable in terms of texture and hygroscopicity.
Regarding the thickness of the plate-like material used in the present invention, for the purpose of facilitating the processing, a too thick material cannot be used, and is 0.5 to
It is preferably about 5 mm, and if it is 0.5 mm or less, the flexural rigidity as a tatami floor cannot be maintained, and if it exceeds 5 mm, the cutting workability and adhesion workability deteriorate, which is not suitable for the purpose.

も好ましい。Examples of the thermoplastic resin foam that can be used in the present invention include foams such as polyurethane, EVA, crosslinked polyethylene, polypropylene and polyethylene. The compressed polyurethane foam is preferable for thin tatami mats because the residual strain is small even after repeated compression. In this case, depending on the thickness of the tatami mat, the thickness of this compressed foam is about 2
mm is preferable. In a common tatami mat, a polystyrene foam is most preferable in terms of heat insulation, lightness, and cushioning.

Since the soft texture of the tatami mat surface can be obtained and the load can be distributed, strength such as bending rigidity can be provided even if the thickness of the tatami mat is reduced. The flexural modulus is 1 m measured at room temperature according to JIS K-7203.
A range of 2000 to 10,000 MPa in m thickness is desirable.

貼着することが好ましい。The laminating means for laminating the plate-like material with the thermoplastic resin foam, insulation board, straw, paper material, etc. is not particularly limited, but in general, tatami thread is often used for sewing. Alternatively, a double-sided adhesive tape or the like can be used as another means. In addition, the tatami mat and the tatami edges that overlap the side edges in the longitudinal direction are sewn with a needle or stapled and attached as in the case of a conventional tatami mat. The tatami mat and the tatami mat used in the present invention are the same as those used in ordinary tatami mats. For example, for tatami mats, weeds made of hemp threads or the like, or synthetic resins such as polypropylene are used. For the tatami mat, ordinary ones such as cotton and synthetic resin are used. To protect the laminated thermoplastic resin foam, insulation board, straw, paper material and the like, it is preferable to attach a sheet of polypropylene cloth or the like to the back surface of the tatami mat.
