▎ 摘  要

NOVELTY - Electromagnetic wave shielding sheet comprises a lower fabric (12) having insulating properties, 0.2-5 pts. wt. graphene powder is mixed with 100 pts. wt. silicon-based resin raw material, and is discharged as molten fine fibers through a nozzle to form a non-woven fabric that is solidified and laminated. An elastic fabric (11) overlapped with the lower fabric, sprayed with water mixed with graphene powder and a crosslinking agent, dipped in water, and dried to be bonded to the lower fabric. The elastic fabric composed of the lower fabric and an upper fabric (13) fixed by quilting by the elastic fabric and a quilting yarn (14) after being located on the upper part of the elastic fabric. USE - The shielding sheet is useful in covers of various electrical and electronic products and interior interiors. ADVANTAGE - The shielding sheet has excellent electromagnetic wave shielding properties to increase electromagnetic wave shielding effect and has effect of reducing damage caused by electromagnetic waves. DESCRIPTION OF DRAWING(S) - The diagram shows a perspective view showing the electromagnetic wave shielding sheet. 11Elastic fabric 12Lower fabric 13Upper fabric 14Quilted yarn
