▎ 摘  要

NOVELTY - Highly conductive, anti-corrosion, anti-aging electric power complex grease comprises 60-70% composite conductive filler, 20-30% base grease and 5-10% mixing aid. The composite conductive filler includes: 4-10 pts. wt. graphene flakes, 8-20 pts. wt. graphite powder, 60-80 pts. wt. silver-coated copper powder, and 6-12 pts. wt. carbon nanofiber powder. The mixing aid comprises 2-4 pts. wt. dispersant sodium polyacrylate, 4-6 pts. wt. fumed silicon dioxide as thickener, 2-4 pts. wt. antioxidant tris(2,4-di-tert-butylphenyl) phosphite, 8-12 pts. wt. bentonite, and 2-6 pts. wt. molybdenum disulfide. USE - Used as highly conductive, anti-corrosion, anti-aging electric power complex grease. ADVANTAGE - The method solves the problems of poor electrical conductivity and low dropping point of the existing electric composite grease. The grease has aging resistance and corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the complex grease.
