Abstract
The present invention relates to a method for manufacturing a transparent sheet, and more specifically, to a method for manufacturing a transparent sheet in which a first transparent resin that is a graft copolymer including a conjugated diene-based polymer and a second transparent sheet that is a graft copolymer including an acrylic polymer, and a transparent sheet manufactured by the method.
Claims15
A method for manufacturing a transparent sheet, the method comprising:
- extruding a first transparent resin from a T-die, wherein the first transparent resin includes a first graft copolymer comprising a conjugated diene-based polymer;
- transferring, to a compression roll, the T-die first transparent resin film extruded from the T-die;
- feeding a second transparent resin film and the T-die first transparent resin film together into the compression roll while bonding the second transparent resin film to at least one surface of the T-die first transparent resin film in response to the T-die first transparent resin film being discharged from the T-die and fed into the compression roll, wherein the second transparent resin includes a second graft copolymer comprising an acrylic polymer;
- and
- laminating the T-die first transparent resin film and the second transparent resin film using the compression roll.

A transparent sheet comprising:
- a first transparent resin film layer comprising a first transparent resin including a graft copolymer including a conjugated diene-based polymer;
- and
- a second transparent resin film layer on at least one surface of the first transparent resin film layer, wherein the second transparent resin film layer comprises a second transparent resin that includes a graft copolymer including an acrylic polymer, and
- wherein the first transparent resin film layer and the second transparent resin film layer each has a uniform thickness in a TD direction of the transparent sheet.
