うに思われる。As the resin forming the synthetic resin foam material 4, vinyl chloride resin, polyurethane resin, acrylobutadiene styrene resin and the like are suitable. If necessary, a foaming agent is added thereto, and the mixture is stirred and applied to the nonwoven fabric 3 and then slightly heated to foam. if,
It is not necessary to heat a resin that foams at room temperature. The thickness of the synthetic resin foam material 4 is preferably 3 to 10 mm, but is not limited thereto. If the thickness is too thin, the sound insulation performance is not good, and if it is too thick, there is an economic problem,
When walking on the floorboard, the sink of the floorboard becomes too large, and the walking feeling deteriorates. The foaming state of the synthetic resin foam material 4 may be either open-cell or closed-cell, but may be a foaming state in which there are many small foams in a large foam. It seems that the foams having overlapping foams are semi-open cells.

トであればよく、厚みは1 〜2mm が好ましい。As shown in FIG. 2, the wood board 1 may be composed of a front wood board 5, a sheet 7 having sound insulation, vibration damping or cushioning properties, and a back wood board 6. In this case, the thickness of the front wood board 5 and the back wood board 6 is 2.5 to 4.0, respectively.
mm is preferred, but is not limited thereto. If the thickness is too small, the rigidity of the floorboard becomes a problem. If the thickness is too large, there is a possibility that trouble may occur at the time of transportation and construction, in addition to the price. Examples of the sound insulation or vibration damping sheet to be attached to the back of the front wooden board 5 include a powdery lead-containing vinyl chloride resin sheet, an inorganic powder-filled rubber sheet, a vinyl chloride resin sheet, and the like, and preferably have a thickness of 0.8 to 2 mm. .
The cushioning sheet may be any sheet having a cushioning property, such as a foamed sheet of natural rubber or synthetic rubber or an olefin-based foamed sheet, and preferably has a thickness of 1 to 2 mm.

材が容易に製造できるという効果も有する。According to the present invention, since a synthetic resin foam material obtained by applying a synthetic resin sol to a nonwoven fabric and foaming is adhered to the back surface of a wooden board having a plurality of grooves formed on the back side, the sound insulating property is improved. In addition to the above, it is possible to obtain a sound-insulating wooden flooring material in which the wooden board and the synthetic resin foam material are not easily separated due to delamination between the nonwoven fabric portions. In addition, there is an effect that a synthetic resin foam material that is less likely to cause delamination in the nonwoven fabric portion can be easily manufactured.
