▎ 摘　　要

NOVELTY - Cable shielding material comprises 65-85 pts. wt. base resin, 10-30 pts. wt. conductive carbon black, 0.5-5 pts. wt. graphene-nano silver composite material and 0.5-3 pts. wt. crosslinking agent. USE - The shielding material is useful in a super-high voltage cable material (claimed). ADVANTAGE - The cable shielding material reduces the amount of conductive carbon black by adding graphene nano-silver composite material, improves the conductivity, and has excellent mechanical properties and processing properties and high the smoothness of the cable surface. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing cable shielding material comprising mixing the base resin, conductive carbon black and graphene-nano silver composite material, extruding to obtain the resin composite material and subjecting the resin composite material and crosslinking agent for post-absorption process to obtain the cable shielding material.
