Description

(1) Technical field [0001] The invention relates to the field of chemical industry, in particular to a high-conductivity nanometer heat-conducting oil and a preparation method thereof. (2) Background technology [0002] Heat transfer oil is a kind of heat transfer medium. It has been widely used in recent years because of its characteristics of uniform heating, accurate temperature adjustment and temperature control, high temperature under low vapor pressure, good heat transfer effect, energy saving, convenient transportation and operation, etc. on various occasions. [0003] Mineral oil and organic synthetic heat transfer oil are the two most commonly used heat transfer oils. Mineral oil has complex components and poor performance stability, while organic synthetic heat transfer oil has excellent thermal stability and wide operating temperature range. It has been widely used in various fields. In addition to the operating temperature range and thermal stability, thermal c...
