NOVELTY - A wear-resistant additive comprises 0.0001-5 wt.% multilayered graphene microfilm, 0.001-5 wt.% humectant, 0-0.5 wt.% emulsifier, 3-5 wt.% dispersant, 3-5 wt.% detergent, 1-2.5 wt.% pour point depressant and balance amount of base oil. USE - Wear-resistant additive for lubricating oil. ADVANTAGE - The wear-resistant additive provides lubricating oil with improved stability, anti-settling property, wear resistance and extreme pressure resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of wear-resistant additive, which involves mixing raw materials, stirring at 80 degrees C for 60-100 minutes, dispersing, homogenizing to obtain emulsion, stirring and homogenizing at pressure of 150-200 MPa for 30 minutes.
