MANUFACTURING METHOD OF DECORATIVE MATERIAL FOR FLOOR, AND DECORATIVE MATERIAL FOR FLOOR
PROBLEM TO BE SOLVED: To provide a decorative material for a floor capable of preventing defective bonding between a resin substrate containing powder and a decorative sheet, without a surface modification treatment for improving wettability.SOLUTION: A manufacturing method of a decorative material 1 for a floor is for manufacturing a decorative material 1 for a floor including: a resin substrate 2 containing powder that contains woody powder consisting of wood powder or paper powder; and a decorative sheet 4 bonded to the resin substrate 2 containing powder. The resin substrate 2 containing powder includes a 20-45 mass% thermoplastic resin, 35-50 mass% powder, and a 25-40 mass% inorganic filler containing metal soap, with regard to the total mass of the resin substrate 2 containing powder, so as to achieve wettability index of 40 dyn or more on a surface of the resin substrate containing powder.SELECTED DRAWING: Figure 1
【課題】本発明は、濡れ性向上の表面改質処理を行わなくても、粉末含有樹脂基材と化粧シートとの貼り合わせ不良を抑制可能な床用化粧材を提供することを目的とする。【解決手段】床用化粧材１の製造方法は、木粉または紙粉からなる木質系の粉体を含有する粉末含有樹脂基材２と、粉末含有樹脂基材２に貼り合わされた化粧シート４とを有する床用化粧材１の製造方法であって、粉末含有樹脂基材２には、粉末含有樹脂基材２の全質量に対し、熱可塑性樹脂を２０質量％以上４５質量％以下含有させ、粉体を３５質量％以上５０質量％以下含有させ、金属石鹸を含む無機充填材を２５質量％以上４０質量％以下含有させることで、粉末含有樹脂基材の表面の濡れ指数を４０dyn以上とした。【選択図】図１
