NOVELTY - A lubricant comprises 15-25 pts. wt. sodium tripolyphosphate, 10-25 pts. wt. calcium stearate, 3-4 pts. wt. polyethylene glycol, 8-16 pts. wt. calcium oxide, 75-100 pts. wt. deionized water, 1-2 pts. wt. hydroquinone and 1-4 wt.% graphene oxide. USE - Lubricant. ADVANTAGE - The lubricant has low friction coefficient and excellent wear resistance, and reduces the agglomeration effect of graphene oxide. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation method of lubricant, which involves adding graphene oxide, hydroquinone and deionized water to high-speed mixer and uniformly mixing, leaving for 15 minutes, then adding sodium tripolyphosphate, calcium stearate, polyethylene glycol and calcium oxide and stirring for 2-3 hours.
