SURFACE MATERIAL FOR RESIN FOAM PLATE MADE OF FILAMENT NONWOVEN FABRIC HAVING HIGH-RIGIDITY AND HIGH ADHESIVE STRENGTH

To provide a surface material for a resin foam plate which has little leakage of a resin composition and is less likely to cause width shrinkage of a nonwoven fabric surface material in a manufacturing process of the resin foam plate and has high adhesive strength to the resin foam plate and is made of a filament nonwoven fabric, and to provide a resin foam plate.SOLUTION: A surface material for a resin foam plate is made of a filament nonwoven fabric, and the filament nonwoven fabric has thermocompression bonding parts with asperity depth of 250 μm or more on one surface or both surfaces thereof, and has a stress of 25 N/3 cm or more when the filament nonwoven fabric is elongated by 5% in the MD direction.SELECTED DRAWING: None 【課題】滲み出しがなく、樹脂発泡板の製造過程において不織布面材の幅入りが発生し難く、そして樹脂発泡板との接着力が高い、長繊維不織布からなる樹脂発泡板用面材及び樹脂発泡板の提供。【解決手段】長繊維不織布からなる樹脂発泡板用面材であって、該長繊維不織布は片面もしくは両面に凹凸深さが２５０μｍ以上の熱圧着部を有し、かつ、該長繊維不織布をＭＤ方向に５％伸長した時の応力が、２５Ｎ/３ｃｍ以上であることを特徴とする樹脂発泡板用面材。【選択図】なし
