FLOOR MATERIAL AND METHOD OF MANUFACTURING THE SAME, AND EMBOSSED FLOOR MATERIAL
To achieve improvement in processability in kneading by two rolls and improvement in processability around a bank by a calendar roll, and to provide a floor material which is superior in shapeability of formation of an uneven shape on a floor material surface.SOLUTION: A floor material 1 has a surface resin layer 2, an upper intermediate resin composition layer 6, a lower intermediate resin composition layer 7, and a back resin layer 5 stacked in order from above. The upper intermediate resin composition layer 6 and the lower intermediate resin composition layer 7 have a melt mass flow rate of 0.5 to 3 g/10 min, and the upper intermediate resin composition layer 6 and the lower intermediate resin composition layer 7 use, as resin components, an olefin-based resin and an olefin-based elastomer, and a low-crystalline resin of 10 to 40% in crystallinity.SELECTED DRAWING: Figure 1
【課題】２本ロールにおける混練時の加工性向上及びカレンダーロールにおけるバンク回りの加工性向上、かつ、床材表面に凹凸形状を形成するための賦形性に優れた床材を提供する。【解決手段】床材１は、上から、表面樹脂層２、上側中間樹脂組成物層６、下側中間樹脂組成物層７、裏面樹脂層５の順番に積層され、上側中間樹脂組成物層６及び下側中間樹脂組成物層７は、メルトマスフローレートが０．５ｇ／１０ｍｉｎ〜３ｇ／１０ｍｉｎであり、上側中間樹脂組成物層６及び下側中間樹脂組成物層７は、樹脂成分としてオレフィン系樹脂及びオレフィン系エラストマー及び結晶化度が１０％〜４０％である低結晶性樹脂が用いられている。【選択図】図１
