▎ 摘 要
NOVELTY - Preparing styrene block copolymer and graphene composite lubricant, comprises adding graphene into base oil, dispersing ultrasonically for 0.5-2 hours, adding styrene block copolymer, then dispersing ultrasonically for 0.5-2 hours. USE - The method is useful for preparing styrene block copolymer and graphene composite lubricant (claimed). ADVANTAGE - The lubricant prevents the agglomeration between the graphene layers, thus suitable for aircraft engine and cold mountain region vehicles. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for composite lubricant.
