▎ 摘　　要

NOVELTY - A high-conductivity nano heat conducting oil comprises 85-100 pts. wt. base oil, 10-15 pts. wt. dispersant, 10-15 pts. wt. antioxidant, 2-5 pts. wt. corrosion inhibitor, 2-4 pts. wt. metal passivant, 2-4 pts. wt. anti-fog agent, 4-9 pts. wt. silica powder, and 0.5-1.5 pts. wt. carbon nanotube or graphene. USE - High-conductivity nano heat conducting oil. ADVANTAGE - The heat conducting oil has good thermal stability, high thermal efficiency, small toxicity, and high safety uses simple raw materials, and has easy production, environmental protection effect, and simple preparation method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the heat conducting oil comprising mixing carbon nanotube and graphene, heating to 350-420 degrees C for 2-4 hours, taking out, and cooling to room temperature; diluting with hydrochloric acid, distilled water and acetone, cleaning, centrifugal separating carbon nanotube and graphene with cleaning liquid, and vacuum drying; ultrasonically dispersing in base oil for 0.5-1 hour; adding dispersant and anti-fog agent and continuously stirring for 2-3 hours; and adding remaining raw materials and stirring for 1-2 hours.
