レタンフォーム等の弾性材が使用されている。The sound insulation wooden floor material is generally composed of a wood member on the surface which should exhibit the appearance and characteristics as a wooden floor and a cushioning material under the surface thereof, and the cushioning material exhibits sound insulation. As such a cushioning material, an elastic material such as a rubber cushion material, a non-woven fabric, a polyethylene foam, a polyurethane foam has been conventionally used.

る。The flooring material using a foamed rubber type special cushioning material which has been used conventionally is characterized by good sound insulation and a small change over time. However, the cost is inevitable. A floor material using a nonwoven fabric or a polyethylene foam having a conventionally known shape has a problem that the sound insulation performance is largely changed with time although the cost is low.

低下する場合もあった。On the other hand, a sound insulating wood-based floor material using polyurethane foam is characterized by a relatively low cost and a small change over time, but a floor material having a sufficient sound insulating property and a feeling of walking is obtained. In order to do so, it is necessary to compress the polyurethane foam by heating and pressurizing it into a sheet-like heat compression foam, and there is room for improvement in cost. In addition, when the floor material is constructed, the adhesive used may permeate into the cushioning material, which may reduce the sound insulation that should be exhibited.

が得られることを見いだし本発明を完成した。The inventor of the present invention has a high sound insulation performance and a so-called “sound insulation performance” by providing a plurality of holes in the elastic foam body, which has a high deformation recovery property and thus the sound insulation performance is not sufficiently obtained in the conventional shape. The present invention has been completed by finding that it is possible to obtain a flooring material which is capable of preventing deterioration of sound insulation performance due to "fatigue" over time and having an excellent walking feeling.

泡体が反発弾性の大きな発泡体となり好ましい。The elastic foam is a foam having a small compression set and a large impact resilience, and corresponds to a rubber-like foam. In particular, an open-cell foam having a cross-linking structure as the constituent molecule is preferable because it has a large impact resilience.

とを防止する作用を有するものである。The term "hole" used herein means a hole penetrating in the thickness direction of the elastic foam. Further, the resin film is a sound insulation as a result of the adhesive used when forming the wood flooring by applying the sound insulation wood-based flooring of the present invention into the holes of the elastic foam and impairing the cushioning property of the elastic foam. It has the effect of preventing the deterioration of the sex.
【００１２】このような構成とすることにより、木質部

なり、さらに低コスト化が達成できる。With such a structure, sufficient sound insulation performance can be obtained without the slits on the back surface of the wooden member. Therefore, the slit forming step can be omitted, and further cost reduction can be achieved. .
【００１３】本発明においては前記有孔弾性発泡体が有

である。In the present invention, it is preferable that the perforated elastic foam is a perforated open cell flexible polyurethane foam.
【００１４】有孔連続気泡軟質ポリウレタンフォームは
反発弾性が良好で、圧縮永久歪みが小さく、特に本発明
における緩衝材として好適である。The open-cell open-cell flexible polyurethane foam has a good impact resilience and a small compression set, and is particularly suitable as a cushioning material in the present invention.

It is preferable that m 3 , the hole diameter is 5 to 60 mm, the perforated area is 25 to 75%, and the thickness t satisfies 3 <t <6 mm. The density of perforated open-cell flexible polyurethane foam is the density of foam without pores.

音床としての均一性が低下し、好ましくない。When the foam density is 10 kg / m 3 or less, the rigidity of the perforated elastic foam becomes too low and the walking feeling deteriorates. If the foam density is 40 kg / m 3 or more, the rigidity of the perforated elastic foam becomes too high, and the sound insulation performance deteriorates. If the hole diameter is less than 5 mm, the number of holes to be provided to obtain a predetermined rigidity is too large to be practical. If the hole diameter exceeds 60 mm, the number of holes is reduced in order to keep the rigidity of the cushioning material as a whole in an appropriate range, and the uniformity as a sound insulation floor is deteriorated, which is not preferable.

It is 0 kg / m 3 . Further, the sound insulation wooden flooring material is generally formed in a unit shape (so-called geese type) in which four long thin boards having a width of 75 mm are displaced by several tens of millimeters and arranged side by side. It Therefore, if the hole diameter is less than 75 mm, the holes can be uniformly arranged on the floor surface, which is particularly preferable. A suitable pore size is 20-40 mm.
【００１８】有孔面積が２５％未満では歩行感は満足で

緩衝材の剛性が必然的に高くなり、結果として遮音性が
低下する。When the perforated area is less than 25%, the walking feeling is satisfactory but the sound insulation is deteriorated. When the perforated area exceeds 75%, the rigidity of the cushioning material inevitably becomes high, resulting in a decrease in sound insulation.

が歩行感は低下する。As a general tendency, when the other conditions are the same and compared, when the foam density d is high, the walking feeling is improved but the sound insulation is deteriorated. On the contrary, when the foam density d is low, the sound insulation of the floor is improved, but the walking feeling is deteriorated. Also, the thickness t
As for the item, when the thickness becomes thin, the walking feeling becomes good, but the sound insulation decreases, and conversely, when t increases, the sound insulation improves, but the walking feeling deteriorates.

が増大する座屈による現象が認められない。In particular, a comparison was made between the case of using a flexible polyurethane foam having no pores as a cushioning material and the case of using the perforated flexible polyurethane foam of the present invention. FIG. 2 shows a floor material using a soft polyurethane foam having no holes with a thickness of 5 mm as a cushioning material and a floor material having holes of 30 mm in diameter in the same soft polyurethane foam.
Applying a 100 mmφ disc, 10 mm / mi
It is the result of measuring the relationship between stress and displacement when compressed at a speed of n using a screw tester using a load cell. From this figure, it can be seen that the flexible polyurethane foam without pores causes a buckling phenomenon and the stress does not increase, but only the displacement increases. No phenomenon due to buckling, where displacement alone increases, is not observed.

ことを、数値データとして裏付けるものである。This buckling is considered to be a cause of a feeling of walking, that is, a so-called floor sickness phenomenon, and it is confirmed by numerical data that the sound insulation floor using the perforated flexible polyurethane foam as a cushioning material improves the walking ability. It is a thing.

ましい。As the open-cell flexible polyurethane foam which is a particularly suitable elastic foam, polyurethane foams well known in the field of flexible polyurethane foam can be used without particular limitation. Such a polyurethane foam is produced by reacting a polyisocyanate compound with a so-called polyol compound in the presence of a foaming agent by mixing components such as a catalyst and a foam stabilizer. Polyether polyols, polyester polyols, polycarbonate polyols and the like are known as polyol compounds, but they can be used in the invention without particular limitation. In particular, when a trifunctional or higher polyfunctional polyol is used, due to the cross-linked structure of the polyurethane molecule due to the branching thereof, it is more than the case of only an allophanate bond or a buret bond,
It is preferable because the above-described change in sound insulation performance over time can be reduced.
