Problems solved by technology

[0002] Due to environmental protection and other reasons, solvent-based metal cleaners are gradually being replaced by semi-solvent and water-based metal cleaners. Compared with semi-solvent-type, water-based metal cleaners have more prominent application advantages; existing metal cleaners The main components of oil agents are strong acids, strong alkalis ...

Abstract

The invention discloses a graphene oil removing agent. The graphene oil removing agent is composed of, by weight part, 1 to 2 parts of fatty alcohol-polyoxyethylene ether, 1 to 2 parts of a functionalcomplex, 0.8 to 1 part of coco fatty acid diethanol amide, 5 to 8 parts of graphene, 1 to 3 parts of cocinic acid, 2 to 4 parts of ethanediamine, 2 to 3 parts of adiponitrile, 0.01 to 0.02 part of stannous octoate, and 0.1 to 0.2 part of dodecyl alcohol. According to the graphene oil removing agent, the dispersion property of graphene in water can be effectively improved, the good oil removal effect is achieved, and in the oil removal process, through the surface friction effect of the graphene, the higher cleaning effect is achieved.
