▎ 摘 要
NOVELTY - High speed composite lubricating oil comprises 5-15 wt.% plant oil, 15-25 wt.% animal oil, 3-25 wt.% polyethylene glycol, 2-6 wt.% ethanol, 0.5-5 wt.% nano graphene, 30-70 wt.% mineral, where granularity of nano graphene is 1-14 nm. USE - Used as high speed composite lubricating oil. ADVANTAGE - The oil: can reduce friction heat productivity; has oxidation resistance; corrosion resistance; low pour point; good stability; and good thermal stability; can widely extend oil life period and can bear heavy loading and high working temperature (-40 degrees C to 150 degrees C).
