▎ 摘　　要

NOVELTY - Preparing graphene based composite machine oil involves preparing base oil raw material, squeezing the fresh oil into water and impurities with ash content, viscosity, pH, pour point, flash point and stability better than the national standard base oil raw material. The reaction of liquid graphene raw material, high temperature dispersant and castor oil is carried out at 200-250 degrees C for 5-10 mins, then again added with high temperature dispersant and reacted for 60 mins at 500 degrees C to obtain the product, which is mixed with the base oil raw material. USE - Method for preparing graphene based composite machine oil (claimed). ADVANTAGE - The method enables to prepare graphene based composite machine oil has strong abrasion resistance strength, can form a super permeable membrane between the moving parts, greatly reduces the wear and power loss, impact noise and vibration of the machine. DETAILED DESCRIPTION - Preparing graphene based composite machine oil involves preparing base oil raw material, squeezing the fresh oil into water and impurities with ash content, viscosity, pH, pour point, flash point and stability better than the national standard base oil raw material. The reaction of liquid graphene raw material, high temperature dispersant and castor oil is carried out at 200-250 degrees C for 5-10 mins, then again added with high temperature dispersant and reacted for 60 mins at 500 degrees C to obtain the product, which is mixed with the base oil raw material, then reacted with 4 wt.% auxiliary material at 45-85 degrees C for 60 mins, then added with antioxidant, corrosion inhibitor, antifoaming agent, anti-wear agent, pour point depressant, anti-rust agent, viscous modifiers to promote further reduction of graphene dissolved and then cooled. The product obtained is statically stored for more than three hours, verified for quality, measured, packaged, measured, filled, sealed, printed, labeled, tested and sent to the warehouse.
