Description of the Related Art Flooring materials in which a decorative surface layer such as veneer or decorative paper is adhered to the surface of a wooden base material are known. As the wood substrate, many materials such as plywood, OSB (Oriented Strand Board), block board, laminated wood, particle board, and the like are used. Then, a large number of grooves are formed at least on the rear surface side to enhance the sound insulation, and a cushioning material such as a foamed synthetic resin sheet or a nonwoven fabric is adhered to the rear surface to improve the buffering property. When a wooden substrate is made from the above-described materials, the surface smoothness is not always sufficient, and when a decorative surface layer such as a veneer is adhered as it is, fine irregularities or cracks (cracks) are formed on the surface of the decorative surface layer. ) May occur. For this purpose, the surface of the wood substrate is usually subjected to some smoothing treatment.

凹凸やクラックが生じないなどの利点がある。[0003] The smoothing treatment is performed by various methods. One of them is to bond and laminate a medium density fiberboard (MDF) or a high density fiberboard (HDF) on the surface of a wooden base material. Such a fibreboard is itself smooth in surface,
Moreover, since it has a certain degree of cushioning property, there is an advantage that even if a veneer or decorative paper is stuck thereon as a decorative surface material, no irregularities or cracks occur on the surface of the veneer.

の曲げ強度も不十分となる。As described above, for example, when it is intended to supplement the surface smoothness of a wooden base material by laminating a medium density fiberboard or a high density fiberboard, Thickness of high density fiberboard is 0.5mm ~ 2.0
It is empirically known that about mm is sufficient. However, such thin fiberboards are expensive and hard to obtain, and medium-density fiberboards and high-density fiberboards themselves have weaker bending strength compared to wood like plywood, Such a thin wood fiber board is easily affected by the behavior of the wood base material as the base material. In particular, when using a wooden substrate having a large number of grooves on the back surface to obtain a floor material with high sound insulation, the bending strength of the wooden substrate tends to be insufficient, and the bending behavior of the wooden substrate is a medium density fiber. It can affect the plate and impair its surface smoothness. In addition, the bending strength of the entire flooring material becomes insufficient.

Compared with wood material such as plywood, the expansion and contraction due to moisture and heat is large (the rate of dimensional change is large). Therefore, even when using a thin material, the dimensional change is limited to a veneer or other surface decorative layer. And may cause cracks in the surface decorative layer. Furthermore, medium-density fiberboards and high-density fiberboards, regardless of their thickness, have the inherent disadvantage that so-called spikes and blisters are likely to occur,
In particular, when placed in a high temperature environment of about 50 ° C., since shrinkage due to heat increases, a floor material formed by bonding and laminating a fiberboard on the surface of a wooden base material is used as a floor material for floor heating. It is difficult.

なる。When a medium-density fiberboard or a high-density fiberboard is used as a wood base material, the above-mentioned problem of surface smoothness does not usually occur. The bending strength of the base material is insufficient, and the bending behavior of the wood base material may directly affect the surface decorative layer such as a veneer. For this purpose, a thin medium-density fiberboard or a high-density fiberboard is usually attached to the surface of a wooden base material, and a veneer or the like is attached thereon. With this type of flooring, cracks can occur in the surface decorative layer due to the large dimensional change rate of medium-density fiberboard and high-density fiberboard compared to plywood, etc., and low bending strength. The nature is even greater.

By attaching a relatively thick medium-density fiberboard or high-density fiberboard to the surface of the wooden base material, the bending behavior of the wooden base material side is not affected by the veneer side, and the bending strength is insufficient. Can be solved temporarily. But,
When a thick fiberboard is attached to a wooden base material to obtain a floor material of a predetermined thickness, the thickness of the wooden base material becomes thinner by the thickness of the fiberboard, and the strength of the floor material itself is reduced.

A number of grooves are formed on at least the back surface of the wooden substrate for the purpose of improving sound insulation. The grooves are about 2 mm in width and 15 mm apart.
It is preferable from the viewpoint of maintaining the bending strength and improving the sound insulation function. A concave groove may be additionally formed from the front side to the back side of the wooden base material.

The wood fiberboard having a size of 5 mm to 2.0 mm and a specific gravity of about 0.4 to 1.2 is a medium density fiberboard (MDF) or a high density fiberboard (HDF). Such a thin wood fiber board is difficult to obtain by a normal manufacturing method. For this purpose, a commercially available thick woody fiberboard obtained by dividing a thick wood fiberboard with a slicer in the thickness direction may be used (for example,
Further, two or more commercially available thick woody fiberboards are glued and laminated using an adhesive to form a flitch, which is sliced by a slicer to obtain a thin fiberboard. (Japanese Patent Application No. 10-273260, filed by the present applicant).
Issue is disclosed in more detail in In the latter case, there is also an advantage that the adhesive used at the time of bonding and laminating penetrates into the wood fiber board, so that the mechanical strength is improved. As an adhesive to be used, an adhesive used for laminating conventional decorative materials such as a formalin-based adhesive such as a urea resin, an acrylic-based adhesive, or a urethane-based adhesive may be used as it is.

The thin sheet may be paper such as Japanese paper, resin-impregnated paper such as phenolic resin-impregnated paper, wire mesh or resin mesh, or wood veneer such as Lauan's rotary veneer. When the thickness of this thin sheet is increased, the thickness of the wooden base material must be reduced, and the strength of the entire flooring material may be reduced. Therefore, it is desirable that the sheet to be arranged is as thin as possible, and preferably about 0.05 mm to 1.0 mm. In the case of resin-impregnated paper, weighing 30 g / m 2-
Those of 60 g / m 2 are suitable.

ト、不織布、合成ゴムシートのようなものが好ましい。By arranging such a thin sheet between the wood substrate and the wood fiber board, the behavior of the wood fiber board due to moisture and heat (such as dimensional change, sprinkling and blistering) is suppressed. It is possible to avoid the occurrence of irregularities and cracks in a surface decorative layer such as a veneer attached to the surface of a wood fiber board. At the same time, the thin sheet also has no function of reinforcing the bending strength of the entire flooring material, and complements the reduction in bending strength due to the formation of a large number of grooves at least on the back surface of the wooden base material.
Thereby, it is avoided that the influence of the bending of the wooden base material appears on the surface decorative layer such as the veneer. As a material having a cushioning function to be adhered to the back surface of the wooden substrate, a material such as a foamed synthetic resin sheet, a nonwoven fabric, or a synthetic rubber sheet is preferable.
