Conduction oil and preparing method thereof

The invention belongs to the field of conduction oil, and relates to conduction oil and a preparing method thereof. The conduction oil is prepared from base oil, antioxidant, antirust agent, dispersant, an anticoking agent, surfactant, a clearing agent and metal passivator. The preparations and the base oil are stirred for 3 h at the temperature of 65 DEG C by weight to obtain the conduction oil. The antioxidant, the clearing agent, the dispersant, the antirust agent, the anticoking agent, the metal passivator, the surfactant and the base oil are compounded, so that the conduction oil with thermal oxidation stability has the advantages that the service life is prolonged, and the conduction oil does not coke easily; production and emission of low-boiling-point substances are reduced, the conduction oil is safe, environmentally friendly, wide in application and reasonable in raw material compatibility, the preparing method is simple, and the raw materials are easy to obtain. 本发明属于导热油领域，涉及种导热油及其制备方法，包括：基础油，抗氧化剂，
