Abstract

The invention provides a high-temperature heat transfer oil composition which consists of the following components in percentage by weight: 95-98% of base oil, 0.01-2.0% of high-temperature antioxidant, 0.01-2.0% of clearing agent, 0.01-1.0% of dispersing agent and 0.01-0.5% of metal deactivator, wherein the base oil is one or more of HVI base oil, naphthenic-base base oil and alkylbenzene. The high-temperature heat transfer oil composition dominated by mineral-oil base oil, provided by the invention, has the advantages of good thermal stability, good heat transfer effect, no toxicity, low cost, easiness in realizing industrial production and the like; and the maximum service temperature is up to 320 DEG C.

Description

technical field [0001] The invention relates to a heat-conducting oil composition, in particular to a mineral oil type high-temperature heat-conducting oil composition. Background technique [0002] Heat transfer oil (referred to as heat transfer oil) is the main type of organic heat carrier, and is widely used in various industries such as petrochemical, textile printing and dyeing, wood processing, food and pharmaceuticals, and paper making. [0003] With the rapid development of my country's industrial production, the demand for heat transfer oil as an efficient and safe heat carrier continues to grow. The annual domestic demand for heat transfer oil is about 200,000 tons. However, the existing mineral oil-based L-QC320 high-temperature heat transfer oil generally has poor thermal stability, severe cracking and polymerization in the heating system, and the high price of synthetic high-temperature heat transfer oil greatly limits its large-scale application in the market. ...
