▎ 摘  要

NOVELTY - Production of graphene material involves mixing 100 pts. wt. graphite, 13-17 pts. wt. polyisobutylene, 3-7 pts. wt. hydroxyethyl cellulose, 4-8 pts. wt. dimethylpyrrolidone, 10-50 pts. wt. polyphenylene ether, 15-25 pts. wt. quartz sand, 20-40 pts. wt. octanoic acid, 15-35 pts. wt. polyethylene, 0.5-2.5 pts. wt. magnesium boride, 11-15 pts. wt. liquid crystal polymers, 50-70 pts. wt. PVC, 0.2-0.8 pt. wt. spherical silica, 60-80 pts. wt. graphene oxide, 1-5 pts. wt. crosslinking agent and 2-6 pts. wt. antioxidant, crushing for 35-45 minutes, sieving through 150-350-mesh sieve, drying for 15-25 minutes, heating at 50-70 degrees C for 30-50 minutes, heating at 85-95 degrees C for 45-65 minutes, stirring uniformly, extruding in twin-screw extruder, granulating, injection-molding, mixing at 220-280 degrees C for 80-90 minutes, calcining in tube furnace under nitrogen protection, leaving still and cooling. USE - Production of graphene material for cantilever beam. ADVANTAGE - The method enables simple and economical production of graphene material with improved Shore hardness of 85-105, corrosion resistance, elongation at break of 400-600%, tensile strength of 75-95 MPa, energy density, electrical conductivity, bending strength of 190-210 MPa and oxygen index of 55-75%. The graphene material improves impact strength of cantilever beam by 130-170 J/m, and is easy to use.
