▎ 摘　　要

NOVELTY - Cable insulation material comprises 10-20 pts. wt. modified bentonite, 80-100 pts. wt. phenolic resin, 10-20 pts. wt. carbon nitride, 20-30 pts. wt. polystyrene, 30-40 pts. wt. epoxy resin, 5-8 pts. wt. antioxidant, 5-10 pts. wt. plasticizer, 10-15 pts. wt. glass fiber, 20-30 pts. wt. neoprene, 20-30 pts. wt. polyvinyl chloride, 10-20 pts. wt. basalt fiber, 0.001-0.003 pts. wt. graphene, 10-20 pts. wt. vinyl silicone rubber, 50-70 pts. wt. polyethylene, and 5-12 pts. wt. modifier. USE - Cable insulation material. ADVANTAGE - The cable insulation material prevents interface corona and discharge phenomena, has better high temperature resistance and puncture resistance, is used for cables, improves cable quality, and is simple and reliable, and suitable for large-scale and industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing cable insulation material involves modifying bentonite by grafting with polyimide after acid pretreatment, mixing modified bentonite with the components of insulating material, poured into high-speed mixer that is uniformly stirred, and then discharged, melted, and injection molded to obtain the cable insulating material.
