Description

technical field [0001] The invention belongs to the field of heat conduction, and in particular relates to an environment-friendly heat conduction oil and a preparation method thereof. Background technique [0002] Due to its good performance, heat transfer oil is widely used in petroleum, chemical industry, oil, textile printing and dyeing, plastic rubber, building materials, road construction machinery, food, paper making, oil refining, carbon and other fields. Although heat transfer oil has many uses, it has the disadvantage that the physical and chemical indicators of heat transfer oil will deviate due to long-term high-temperature use, which greatly limits its service life. [0003] At present, domestic production is mostly based on mineral heat transfer oil. As we all know, mineral oil is obtained from petroleum by-products through a series of purification, fractionation, and addition of additives. Its biggest feature is that it is relatively cheap and suitable for lo...

AI Technical Summary

Problems solved by technology

However, when mineral oil is heated, it is easy to show various decomposition temperatures with the increase of temperature, which makes it easy to decompose and coke when it is used at high temperature for a long time, block the pipeline, affect the heat transfer efficiency, consume a lot of energy, and the indirect cost is expensive. There are many hidden dangers of accidents and short service life, which makes it difficult to meet the performance requirements of actual working conditions

In addition, with the continuous rise of international oil prices, the cost of using traditional mineral heat transfer oil will become higher and higher, and mineral heat transfer oil is difficult to decompose in nature, causing increasingly serious pollution to the natural environment

[0004] Although traditional heat transfer oil products have certain high-temperature thermal stability and heat transfer characteristics, due to their own structure, they have shortcomings such as short service life and easy coking, which affect the normal and safe operation of the system, high-temperature thermal stability and The heat transfer characteristics cannot meet the processing temperature and heat transfer requirements of new industrial technologies and processes, and a new heat transfer oil product with high temperature oxidation resistance is required to match it
