NOVELTY - Preparing anti-wear agent comprises e.g. providing dodecylamine-modified graphene oxide, ferric (II) chloride hexahydrate, and sodium acetate, ethylene glycol and uniformly stirring to obtain solution A, transferring solution A into a high-pressure reaction kettle and carry out the reaction, reacting, cooling to room temperature to obtain solution B, subjecting solution B to a separation treatment using a magnet, to obtain a reaction product A and a reaction solution, washing product A with ultrapure water and anhydrous alcohol to obtain reaction product B and drying to obtain the product. USE - The method is useful for preparing anti-wear agent (claimed). ADVANTAGE - The anti-wear agent has good bearing capacity and is resistant to extreme pressure (claimed). DETAILED DESCRIPTION - Preparing anti-wear agent comprises providing 130-170 mg dodecylamine-modified graphene oxide, 550 -650 mg ferric (II) chloride hexahydrate, and 1-4 mg sodium acetate, 50-70 ml ethylene glycol and uniformly stirring to obtain solution A, transferring solution A into a high-pressure reaction kettle and carry out the reaction, reacting at 160-200 degrees C for 14-18 hours, cooling to room temperature to obtain solution B, subjecting solution B to a separation treatment using a magnet, to obtain a reaction product A and a reaction solution, washing reaction product A with ultrapure water and anhydrous alcohol for 5-15 times to obtain reaction product B and drying at 45-55 degrees C to obtain the product. An INDEPENDENT CLAIM is also included for energy saving environment-friendly engine oil anti-wear agent comprising magnetic extreme pressure anti-wear agent, specifically comprises 70-90 pts. wt. base oil, 0.1-0.5 pts. wt. anti-wear agent, 0.5-1 pts. wt. magnetic extreme pressure anti-wear agent, 0.1-0.8 pts. wt. high temperature antioxidant, 2-6 pts. wt. detergent, 3-5 pts. wt. dispersant, 5-10 pts. wt. viscosity index improver, 0.1-0.3 pts. wt. pour point depressant and 0.0001-0.0002 pts. wt. antifoaming agent.
