NOVELTY - Graphene lubricating oil comprises 50-60 pts. wt. high-performance vulcanized lard oil, 10-20 pts. wt. vulcanized fatty acid ester, 10-20 pts. wt. water, 5-10 pts. wt. epoxy linseed oil, 2-5 pts. wt. rust inhibitor, 1-5 pts. wt. antioxidant and 6-15 pts. wt. graphene slurry. USE - The lubricating oil is useful for copper wire drawing (claimed). ADVANTAGE - The lubricating oil: reduces surface wear of copper wire when drawing; does not easy to break the wire; improves yield rate of pulled wire; reduces surface scratches; reduces impedance of copper wire and increase conductivity; and improves the quality of the copper wire. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene lubricating oil comprising (a) pre-mixing high-performance vulcanized lard oil, vulcanized fatty acid ester and water, stirring for 10-30 minutes, and (b) adding epoxy linseed oil into mixed solution, rust inhibitor and antioxidant, stirring for 10-30 minutes, adding graphene slurry, continuing stirring for 30-40 minutes to obtain lubricating oil products.
