NOVELTY - Graphene lubricant additive comprises 10-15 pts. wt. graphene modified film-forming aid, 3-5 pts. wt. calcium linoleate soap, 0.4-1 pt. wt. tert-butyl hydroquinone and 2-3 pts. wt. sorbitan monostearate. USE - Graphene lubricant additive. ADVANTAGE - The additive improves the mechanical strength of methylcellulose film formation, improves the lubricating performance of traditional oils, and improves the quality of finished oil. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the additive, involving (a) adding tert-butyl hydroquinone to 4-7 times absolute ethanol, evenly stirring, adding calcium linoleate soap, increasing the temperature to 60-70 degrees C, heat-preserving, and stirring for 1-2 hours, and (b) adding graphene modified film-forming aid and sorbitan monostearate, evenly stirring, and removing ethanol by rotary evaporation to obtain the product.
