FOAMING AGENT FOR MANUFACTURING GYPSUM BOARD
To provide a foaming agent for manufacturing a gypsum board, capable of forming foam-derived voids almost uniform in size, in the gypsum board having few fine foams.SOLUTION: A foaming agent for manufacturing a gypsum board contains an alkyl sulfate (A) represented by the following general formula (1): R1OSO3M1 (In the formula, R1 represents a 9-11C branched alkyl group having a branching degree of 1.8 to 3.0, obtained by subtracting 1 from the number of methyl groups determined by 1H-NMR measurement; and M1 represents an alkali metal, ammonium or organic ammonium).SELECTED DRAWING: Figure 1
【課題】 石膏ボードに微細泡が少なく、大きさがほぼ均一な泡由来の空隙を形成することができる石膏ボード製造用起泡剤を提供すること。【解決手段】下記一般式（１）で表されるアルキル硫酸塩（Ａ）を含有する石膏ボード製造用起泡剤。Ｒ１ＯＳＯ３Ｍ１（１）（式中、Ｒ１は１Ｈ－ＮＭＲ測定により求められるメチル基数から１を引いて得られる分岐度が１．８～３．０である炭素数９～１１の分岐アルキル基を示し、Ｍ１はアルカリ金属、アンモニウム又は有機アンモニウムを示す。）【選択図】 図１
