MANUFACTURING METHOD FOR CONDUCTIVE THEOMOPLASTIC POLYURETHNAE SHEET AND THEOMOPLASTIC POLYURETHNAE SHEET USING THE SAME

摘要

PURPOSE: A manufacturing method of an electroconductive thermoplastic polyurethane sheet, and the electroconductive thermoplastic polyurethane sheet manufactured therefrom are provided to secure an excellent electrical resistance and abrasion resistance. CONSTITUTION: A manufacturing method of an electroconductive thermoplastic polyurethane sheet comprises the following steps: forming a carbon nanotubes/thermoplastic polyurethane master batch by dispersing carbon nanotubes into a solvent and mixing the dispersed mixture with thermoplastic polyurethane; and mixing the carbon nanotubes/thermoplastic polyurethane master batch with a thermoplastic polyurethane resin and processing. The carbon nanotubes/thermoplastic polyurethane master batch contains 0.5~4.8wt% of carbon nano tube, 94.7~99.2wt% of thermoplastic polyurethane, and 0.3~0.5wt% of antioxidant.
