| titleOfInvention | Graphene heat conduction oil and preparation method thereof |
| abstract | The invention relates to the field of chemical industry, in particular to graphene heat conduction oil and a preparation method thereof. The graphene heat conduction oil is prepared from, by weight, 80-90 parts of base oil, 3-8 parts of graphene, 2-5 parts of a dispersing agent and 1-5 parts of an auxiliary agent; the graphene comprises 10-20 wt% of modified graphene, the dispersing agent comprises sugar ester and sulfonic acid, and the weight ratio of the sugar ester to the sulfonic acid is (0.05-0.2): 1, mixing base oil, graphene and a dispersing agent, carrying out ultrasonic treatment at 40-60 ℃ for 1-2 hours, adding an auxiliary agent, and stirring to obtain the heat conduction oil. The graphene heat conduction oil provided by the invention has good heat conductivity and heat stability, can be stably stored for a long time under the condition of normal temperature or high temperature, and has good rheological property and heat exchange property. |
