FIRE-RETARDANT FLUOROPLASTIC FILM LAMINATED STEEL PLATE

摘要

PROBLEM TO BE SOLVED: To manufacture a fluoroplastic film laminated steel plate of superior fire retardancy used for an interior member and the like. SOLUTION: A polyolefin resin film containing aluminum hydroxide or magnesium hydroxide as a fire retardant is laminated on the surface of a fire-retardant fluoroplastic film laminated steel plate through a first bonding agent layer, and also a transparent ethylene-tetrafluoroethylene copolymer film of 10-50μm film thickness is provided thereon through a second bonding agent layer. Also for the purpose of providing design properties, a printed ink layer can be formed between the polyolefin resin film and the second bonding agent layer.
