NOVELTY - Lubricating oil comprises 90-97 pts. wt. light white oil, 1-2 pts. wt. methyl oleate, 0.5-1 pts. wt. lauryl alcohol, 0.1-0.2 pts. wt. graphene oxide-based nano-silicon dioxide, 0.5-1 pts. wt. isooctyl acid phosphate octadecylamine salt and 0.1-0.3 pts. wt. octadecenoic acid. USE - The lubricating oil is useful for rolling aluminum plate and aluminum foil (claimed). ADVANTAGE - The lubricating oil: synergistically acts graphene oxide-based nano-silica, isooctyl acid phosphate octadecylamine salt and octadecenoic acid; improves the oil film bearing capacity of lubricating oil; and has excellent lubricity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the lubricating oil, comprises adding graphene oxide-based nano-silicon dioxide, isooctyl acid phosphate octadecylamine salt and octadecenoic acid into light white oil in sequence, heating and stirring to obtain mixed solution, adding methyl oleate and lauryl alcohol to the above mixture in turn, heating and stirring, cooling to room temperature, and obtaining uniform transparent color oil body, i.e. obtaining the lubricating oil for rolling the aluminum plate and aluminum foil.
