▎ 摘  要

NOVELTY - Lubricating oil additive comprises graphene nanosheet and dispersant which is adsorbed on graphene nanosheet through non-covalent bond. USE - The lubricating oil additive or refrigerating machine oil is useful in compressor (claimed). ADVANTAGE - The additive prevents agglomeration and precipitation between graphene nanosheet; ensures that dispersant does not generate new functional group in molecular structure of graphene nanosheet and does not destroy molecular structure of graphene itself; can retain the chemical properties of graphene itself and has excellent lubricating performance. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: preparing lubricating oil additive comprising mixing graphene nanosheet with dispersant and carrying out stirring under ultrasonic condition; a refrigerating machine oil comprising base oil and lubricating oil additive; a compressor comprising a shell body and a moving part is arranged in the shell body. The lubricating oil additive or the refrigerating machine oil is provided in the shell body to lubricate the moving parts when the compressor is operating; and a refrigeration device comprising compressor.
