▎ 摘　　要

NOVELTY - Graphene regenerating agent comprises 100-200 pts. wt. graphene, 50-100 pts. wt. graphite, 10-20 pts. wt. solid lubricant, 10-20 pts. wt. liquid lubricant, 200-400 pts. wt. water, 10-20 pts. wt. rubber, 1-3 pts. wt. sulfur, 2-8 pts. wt. compounding agent, 10-20 pts. wt. composite nano-carbon material, 25-30 pts. wt. modified porous graphene antibacterial masterbatch, 2-4 pts. wt. poly-N-vinylacetamide, 1-3 pts. wt. silicone oil, 1-3 pts. wt. paraffin wax, 2-6 pts. wt. antiaging agent, 4-8 pts. wt. foaming agent, 10-30 pts. wt. regenerating agent and 2-4 pts. wt. surfactant. USE - As a graphene regenerating agent. ADVANTAGE - The agent realizes the low-carbon discharge during process, and is environmentally-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the agent involving (a) immersing graphite in liquid lubricant one and a half hours at a pH of 5, (b) mixing graphene, solid lubricant and rubber thoroughly, and leaving still for half an hour, (c) adding compounding agent to the mixed solution prepared in step (b), (d) adding paraffin wax and antioxidant to the solution obtained in step (a) and carrying out banburying for 10-15 minutes at 120-130 degrees C, (e) adding the mixed material, thining, adding the thinned material into an internal mixer, adding composite nano-carbon material, modified porous graphene antibacterial masterbatch, poly-N-vinylacetamide and silicone oil, and mixing for 20-30 minutes at 120-140 degrees C, (f) adding foaming agent, regenerating agent and surfactant to the obtained material and banburying the obtained material for 5-8 minutes at 80-100 degrees C, (g) thinning the resulted material and extruding using an open mill to obtain graphene masterbatch, and (h) carrying out compression molding, continuously molding, winding molding, pultrusion molding, lamination and coiling molding, centrifugal molding, casting molding, elastomer resin molding and enhanced reaction injection molding processes to the particles to form desired shape.
