SOUND ABSORPTION BUILDING MATERIAL AND MANUFACTURING METHOD THEREOF
PROBLEM TO BE SOLVED: To provide a sound absorption building material A capable of achieving high sound absorption performance corresponding to sound absorption coefficient NRC of 0.7 or higher even if a nonwoven fabric is laminated on a surface of a base material 1 made of rock wool.SOLUTION: A sound absorption building material A is made by forming many bottomed pin holes 2,2,...with hole diameter d of 2.0 to 3.0 mm at a constant pitch p on a surface of a base material 1 made of rock wool, laminating a nonwoven fabric sheet 5 made of a nonwoven fabric on the surface of the base material 1, and coating the surface of the nonwoven fabric sheet 5 with air permeable coating to form a coating 8.SELECTED DRAWING: Figure 1
【課題】吸音建材Ａとして、ロックウールからなる基材１の表面に不織布が積層されていても、吸音率ＮＲＣで０．７以上の高い吸音性能が得られるようにする。【解決手段】吸音建材Ａは、ロックウールからなる基材１の表面に穴径ｄが２．０〜３．０ｍｍの多数の有底状ピン穴２，２，…が一定のピッチｐで形成され、その基材１の表面に不織布からなる不織布シート５が積層され、不織布シート５の表面が通気性塗料によって塗装されて塗膜８が形成されている。【選択図】図１
