Abstract

PURPOSE:To easily realize the strong bonding in a multi-layer sheet by a method wherein the surface to be bonded of a fluoroplastic sheet is surface-treated, and a sheet to be bonded in piled up each other with a resin composition consisting of ethylene-ethyl acrylate-maleic anhydride terpolymer (EEM resin) and ethylene-glycidyl methacrylate-vinyl acetate terpolymer (EGV resin) as adhesive linkage and, after that, pressurized and finally heat-treated. CONSTITUTION:By employing resin composition, which consisting of EEM resin and EGV resin meted in an extruder and is melt-extruded from a sheeting die 1 under molten state as adhesive a surface-treated fluoroplastic sheet 4 and a sheet to be bonded 3 are strongly pressed against a metallic cooling roll 5 with a press roll 2. At that time, the surface temperature of the cooling roll 5 is set to be below the melting points of the fluoroplastic sheet and of the sheet to be bonded. In addition, the temperatures of cooling rolls 6 and 7 are lowered stepwise. However, said sheets are bonded to each other during running through the cooling rolls 5-7 so as to be turned into a multi-layer sheet. Further, the bonding becomes perfect by giving the predetermined thermal history to the sheet.
