NOVELTY - Graphene industrial gear oil comprises 3-4 pts. wt. paraffin modified graphene, 0.1-0.2 pts. wt. allyl thiourea, 1-2 pts. wt. dimethylaminopropylamine, 180-200 pts. wt. base oil, and 2-3 pts. wt. gear oil additive. USE - Graphene industrial gear oil. ADVANTAGE - The paraffin-modified graphene has good lubricating property and good anti-rust property, improved surface activity, and increased dispersion in base oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene industrial gear oil comprising taking 36-40 wt.% base oil, adding dimethylaminopropylamine, stirring uniformly, adding paraffin-modified graphene, stirring at 55-60 degrees C, keeping the temperature for 20-30 minutes to obtain pre-dispersion liquid, taking allyl thiourea, adding to the remaining amount of base oil, stirring and uniformly mixing with the pre-dispersion liquid, adding gear oil additive, and ultrasonically processing for 10-15 minutes.
