MULTILAYER THERMOPLASTIC RESIN SHEET MANUFACTURING METHOD, AND MULTILAYER THERMOPLASTIC RESIN SHEET |
摘要 |
A method for efficiently manufacturing multi-layer thermoplastic resin sheet without damaging foamed resin layer, and a multi-layer thermoplastic resin sheet are provided. After bringing a thermoplastic resin film 19 into close contact with either one of a metal endless belt 15 (with surface roughness Ra: less than or the same as 0.5 mu m) or a roller 16, a foamed resin sheet 18 from a die 11 or a feed roller is superposed onto the thermoplastic resin film 19, and the laminated thermoplastic resin film 19 and the foamed resin sheet 18 are sandwiched and sheet-pressed between the belt 15 and the roller 16 to manufacture double-layer thermoplastic resin sheet 24, during the sheet-pressing operation, sheet-pressure applied is 0.05 to 1.00MPa, and sheet-pressure acting time is 0.5 to 10.0 seconds. <IMAGE> |
