Environment friendly energy-efficient heat conduction oil

Abstract

The environment friendly energy-efficient heat conduction oil of the present invention is composed of 90-95% of base oil and 10-5% of other additives. The invention has advantages of low viscosity, low condensation point, high boiling point, low volatility, low acid value, free of smell, non-toxicity, high viscosity index, high flash point, high initial boiling point, high specific heat capacity, low temperature flow performance, material compatibility of system, high tepid stability, antioxidation stability, anti-corrosivity, antirust performance, peace and quiet dispersion performance, high heat conduction coefficient, biodegradability, and other performances. The index of each performance accords with the usage requirement, and can satisfy the technology requirements of the GB23971-2009 heat conduction oil with L-QB, L-QC, L-QD quality grade specifications and the performance requirements of those with temperature grades: 280, 300, 310, 320, 330, 340 and 350.

Description

technical field [0001] The invention belongs to heat conduction medium, in particular to an environment-friendly and energy-saving heat conduction oil. Background technique [0002] Heat transfer oil, also known as heat transfer fluid, has been widely used as a heat transfer medium in petroleum, petrochemical, coal chemical, electric power, metallurgy, textile printing and dyeing, non-ferrous metals, building materials, grain, oil chemistry, food processing, medicine, electronics, etc. industry. It has high heat transfer efficiency, non-toxic, high initial boiling point, good thermal stability, low viscosity, low freezing point, low water absorption, easy to adjust and control temperature, no corrosion to equipment, high cost performance, convenient recycling, Low investment and other advantages, and its use and consumption are also increasing. [0003] At present, domestic production is mostly based on mineral heat transfer oil. As we all know, mineral oil is obtained fr...

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
