Manufacturing method of extruded resin plate and extruded resin plate

摘要

A step of extruding from a T-die 11 in a molten state a thermoplastic resin laminate 16 in which a layer containing a methacrylic resin having a glass transition temperature of 115° C. or higher is laminated on at least one side of the layer containing polycarbonate, , at the position where the thermoplastic resin laminate 16 is peeled off from the last winding cooling roll 14, the temperature of the entire resin is -2°C to +15°C with respect to the glass transition temperature of the polycarbonate-containing layer. of the extruded resin sheet in which the circumferential speed ratio (V4/V2) of the circumferential speed V4 of the take-up roll 15 and the circumferential speed V2 of the second cooling roll 13 is 0.98 or more and 1.01 or less. manufacturing method.
