▎ 摘　　要

NOVELTY - Graphene heat transfer oil comprises 80-90 pts. wt. base oil, 3-8 pts. wt. graphene, 2-5 pts. wt. dispersant, and 1-5 pts. wt. auxiliary agent, where the base oil is a synthetic or mineral oil. USE - Used as graphene heat transfer oil. ADVANTAGE - The graphene heat-conducting oil has good thermal conductivity and thermal stability, can be stored stably for a long time under normal temperature or high temperature conditions, and has good rheological performance and heat exchange performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing graphene heat transfer oil, comprising mixing a base oil, graphene, and a dispersant, sonicating at 40-60 degrees C for 1-2 hours, adding an auxiliary agent, and stirring.
