High-temperature heat-conducting oil and preparation method thereof

Abstract

The invention belongs to the technical field of chemical engineering, and particularly relates to high-temperature heat-conducting oil and a preparation method thereof. The high-temperature heat-conducting oil is prepared from the following raw materials in parts by weight: 99-99.5% of synthetic aromatic base oil, 0.01-1.0% of a high-temperature antioxidant, 0.01-1.0% of a detergent, 0.01-1.0% of a dispersant and 0.01-1.0% of a metal deactivator. The synthetic aromatic base oil comprises more selected from hydrogenated terphenyl, terphenyl, hydrogenated quaterphenyl, hydrogenated pentaphenyl, diisopropylnaphthalene, diisopropylbiphenyl, 1,2,3,4-tetrahydro-6-(1-phenylethyl) naphthalene, dibenzyltoluene, benzyltoluene and xylyl ether. The high-temperature heat-conducting oil composition taking the synthetic aromatic hydrocarbon base oil as the main component has the advantages of good heat transfer effect, easiness in industrial production and the like, and still has relatively good stability under the condition that the highest use temperature is 350 DEG C.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, and in particular relates to a high-temperature synthetic heat-conducting oil combination and a preparation method thereof. Background technique [0002] Heat transfer oil is a safe and efficient heat transfer medium. It is an organic heat carrier. According to its structure, it can be divided into hydrocarbons, ethers, alcohols, silicone oils, halogen-containing hydrocarbons, and nitrogen-containing heterocycles. At present, the most used heat transfer oil at home and abroad is hydrocarbon, that is, only two kinds of elements are carbon and hydrogen. Compared with water as a heat transfer medium, heat transfer oil has the characteristics of high temperature, low vapor pressure and convenient use. It also has the advantages of good heat transfer effect and uniform heating. It is widely used in heating, cooling, waste heat recovery, solar energy, etc. In the industrial field and in dail...
