Fullerene nano functional lubricating oil

Abstract

The invention provides fullerene nano functional lubricating oil, and belongs to the technical field of lubricating oil. The invention is prepared from the following components in percentage by mass:0.1 to 0.5 percent of nanoscale fullerene, 3 to 5 percent of detergent, 2 to 5 percent of dispersant, 2 to 4 percent of antioxidant and anti-corrosion agent, 3 to 6 percent of high-temperature antioxidant, 1 to 3 percent of viscosity index improver, 0.1 to 0.8 percent of pour point depressant and the balance of base oil. The preparation method comprises the following steps: firstly, adding the base oil into a reactor, and starting a stirrer; then sequentially adding a detergent, a dispersant, an anti-oxidation and anti-corrosion agent, a high-temperature antioxidant, a viscosity index improverand a pour point depressant into the base oil, starting to heat, after the temperature reaches 70 DEG C, adding nanometer fullerene and the dispersant into the reactor, continuously heating to 100-150 DEG C, and keeping the constant temperature for 2-5 hours to obtain the finished product oil; the finished product oil meets the American APISN standard. The fullerene nano-functional lubricating oil does not change the original performance of the lubricating oil, and is non-toxic and harmless to human bodies; the finished product oil is particularly suitable for various working conditions suchas heavy load, low speed, high temperature and high environmental pollution.

Description

technical field [0001] The invention relates to a fullerene nano functional lubricating oil, which belongs to the technical field of lubricating oil. Background technique [0002] In industrial production, as long as the moving parts are inseparable from lubricants, the service life and noise of the machine have been greatly improved. But each lubricant has its own disadvantages. For example, the disadvantages of calcium-based grease are: poor heat resistance, and the maximum operating temperature is 60°C. Disadvantages of sodium-based grease: general heat resistance, better than calcium-based grease, generally used at a temperature of about 80°C, general anti-rust performance, and poor water resistance. Disadvantages of aluminum-based grease: poor heat resistance and water resistance, the maximum operating temperature is 50°C. Disadvantages of general-purpose lithium-based grease and extreme-pressure lithium-based grease: both have a maximum operating temperature of 120°C...

AI Technical Summary

Problems solved by technology

However, each lubricant has its own disadvantages. For example, the disadvantages of calcium-based grease are: poor heat resistance, and the maximum operating temperature is 60°C

Disadvantages of sodium-based grease: average heat resistance, better than calcium-based grease, generally used at a temperature of about 80°C, average anti-rust performance, poor water resistance

Disadvantages of aluminum-based grease: poor heat resistance and water resistance, maximum operating temperature of 50°C

Disadvantages of general-purpose lithium-based grease and extreme-pressure lithium-based grease: both have a maximum operating temperature of 120°C

Disadvantages of molybdenum disulfide extreme pressure lithium base grease: the maximum operating temperature is 120°C, not suitable for high speed, light load and low temperature conditions

Disadvantages of bentonite lubricating grease: poor rust resistance, the maximum operating temperature is around 130°C, and the price is relatively high

Disadvantages of complex calcium-based grease: the highest use temperature is around 130°C, and the price is relatively high

The disadvantages of extreme pressure complex lithium-based grease are: the highest use temperature is 160°C, and the price is relatively high

Disadvantages of polyurea grease: it has certain radiation resistance and high price

The disadvantages of composite aluminum-based grease are: high price, short service life of bearings, composite aluminum soap has relatively strong thickening ability to mineral oil, but poor thickening ability to synthetic oil, such as silicone oil, ester oil, PAG, etc. , not even fat
