NOVELTY - Water-soluble fluorocarbon graphene engine oil comprises 0.17-9 pts. wt. fluorine-carbon alcohol, 0.023-1.6 pts. wt. graphene, 29.7-62.3 pts. wt. propanediol, 29.7-62.3 pts. wt. glycol, 29.7-62.3 pts. wt. triethylene glycol, 0.97-5.2 pts. wt. borate, 1-9 pts. wt. ethylene oxide and 0.31-5 pts. wt. phosphate. USE - Water-soluble fluorocarbon graphene engine oil. ADVANTAGE - The water-soluble fluorocarbon graphene engine oil is eco-friendly and easy to dissolve in water, has easy degradation, good lubricity, low pour point viscosity and small viscosity drops with high boiling point, and saves energy. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing water-soluble fluorocarbon graphene engine oil, which involves: (A) mixing fluorocarbon alcohol, propanediol, glycol and triethylene glycol uniformly, then stirring and heating, raising temperature slowly to 80-170 degrees C; (B) adding ethylene oxide, reacting for 120-200 minutes, reducing the temperature to 60-70 degrees C, reacting for 180 minutes, then reducing temperature to 65 degrees C; and (C) adding boric acid ester, phosphate, graphene, esterifying reaction to adjust pH value to 6.0-8.0 to obtain water-soluble fluorocarbon-graphite oil.
