MULTILAYER RESIN SHEET, LAMINATED SHEET, METHOD FOR PRODUCING MULTILAYER RESIN SHEET, METHOD FOR PRODUCING LAMINATED SHEET, AND METHOD FOR PRODUCING FOAMED WALL PAPER
PROBLEM TO BE SOLVED: To provide a multilayer resin sheet which can be efficiently produced by extrusion molding while having a resin layer containing a foaming agent; a laminated sheet and a method for producing them; and a method for producing foamed wall paper.SOLUTION: In a multilayer resin sheet 20 having a first layer 1 formed from a foaming agent-containing resin composition that contains a first resin content, a filler and a foaming agent, and a second layer 2 formed from a foaming agent-free resin composition that contains a second resin content and does not contain a foaming agent, a thickness Tof the first layer 1 is smaller than a thickness Tof the second layer 2. Tand Tsatisfy a relationship of the following expression: T×2≤T. The first resin content contains an ethylene-vinyl acetate copolymer or an ethylene copolymer having a melting point of 100°C or lower, and a silane crosslinkable resin.SELECTED DRAWING: Figure 2
【課題】発泡剤が含まれる樹脂層を有しながらも押出成形によって効率よく生産することができる多層樹脂シート、積層シート及びこれらの製造方法、並びに発泡壁紙の製造方法の提供。【解決手段】第１の樹脂分と、充填剤と、発泡剤と、を含む発泡剤含有樹脂組成物からなる第１層１と、第２の樹脂分を含み、発泡剤を含まない発泡剤非含有樹脂組成物からなる第２層２とを有する多層樹脂シート２０であって、第１層１の厚みＴ１が第２層２の厚みＴ２よりも小さい、多層樹脂シート２０。Ｔ１とＴ２が下記式の関係を満たす多層樹脂シート。Ｔ１×２≦Ｔ２。第１樹脂成分が１００℃以下の融点を有するエチレン−酢酸ビニル共重体又はエチレン共重合体と、シラン架橋性樹脂とを含む多層樹脂シート【選択図】図２
