Abstract

The invention belongs to the technical field of chemical industry and especially relates to a high-temperature resisting heat conductive oil. The high-temperature resisting heat conductive oil contains the following components in parts by weight: 80-120 parts of base oil, 1-3 parts of cleaning agent, 5-8 parts of dispersing agent, 5-10 parts of high-temperature antioxidant, 1-3 parts of anti-coking agent, 1-3 parts of pour point reducer, 1-3 parts of viscosity reducer and 1-2 parts of metal deactivator. The high-temperature resisting heat conductive oil is higher in safety, low in product toxicity, wide in raw material resource and low in cost. The compounded oil is high in thermal stability, low in low temperature viscosity and high in thermal efficiency, has the advantages of long service life and difficulty in coking, is capable of reducing generation and emission of low-boiling point substance, is safe and environment-friendly and is wide in application.

Description

[0001] (1) Technical field [0002] The invention belongs to the technical field of chemical industry, and in particular relates to a high-temperature-resistant heat-conducting oil. [0003] (2) Background technology [0004] High temperature heat transfer oil is an important petroleum product with high technical content. Compared with gasoline, kerosene, diesel oil, heavy fuel oil and other petroleum products, although its quantity is small, it has many varieties and specifications. [0005] High temperature resistant heat transfer oil mainly plays the roles of lubrication, cooling, rust prevention, cleaning, sealing and buffering. High temperature heat transfer oil is composed of base oil and additives. Base oil is the main component of high temperature heat transfer oil, which determines the basic properties of high temperature heat transfer oil. Additives can make up for and improve the performance of base oil. The new performance is an important part of high temperature h...
