SOUNDPROOF FLOOR MATERIAL
To restrict a change of a size of a soundproof floor material during dryness and moisture absorption.SOLUTION: The soundproof floor material 50 comprises a first wooden fiber plate layer 20 with a plurality of grooves G at a lower surface, a second wooden fiber plate layer 30 at an upper surface side of the first wooden fiber plate layer 20, a surface decorative layer 35 at an upper surface side of the second wooden fiber plate layer 30 and a buffer layer 15 at a lower surface side of the first wooden fiber plate layer 20, and the surface decorative layer 35 has a moisture permeability equal to or smaller than 10 g/m2 24h, the first wooden fiber plate layer 20 and the second wooden fiber plate layer 30 are bonded by a moisture-proof layer 25 provided on a whole surface between the first wooden fiber plate layer 20 and the second wooden fiber plate layer 30, the moisture-proof layer 25 is formed by a reactivity hotmelt adhesive and has a moisture permeability equal to or smaller than 10 g/m2 24h and the plurality of grooves G are arranged not to reach at the moisture-proof layer 25.SELECTED DRAWING: Figure 1
【課題】乾燥時及び吸湿時の防音床材の寸法変化を抑制する。【解決手段】複数の溝Ｇが下面に設けられた第１木質繊維板層２０と、第１木質繊維板層２０の上面側に設けられた第２木質繊維板層３０と、第２木質繊維板層３０の上面側に設けられた表面化粧層３５と、第１木質繊維板層２０の下面側に設けられた緩衝層１５とを備えた防音床材５０であって、表面化粧層３５は、１０ｇ／ｍ２・２４ｈ以下の透湿度を有し、第１木質繊維板層２０及び第２木質繊維板層３０は、第１木質繊維板層２０及び第２木質繊維板層３０の間に全面に設けられた防湿層２５により互いに接着され、防湿層２５は、防湿性を有する反応性ホットメルト接着剤により形成され、１０ｇ／ｍ２・２４ｈ以下の透湿度を有し、複数の溝Ｇは、防湿層２５に到達しないように設けられている。【選択図】図１
