Problems solved by technology

But each lubricant has some disadvantages of its own
For example, the disadvantages of calcium-based grease: poor heat resistance, the maximum operating temperature is 60 ° C; the disadvantages of sodium-based grease: general heat resistance, better than calcium-based grease, the general operating temperature is 80 ° C; general lithium-based grease Disadvantages of extreme pressure lithium-based grease: both have a maximum service temperature of 120°C; disadvantages of molybdenum disulfide extreme-pressure lithium-based grease: a maximum service temperature of 120°C, not suitable for high-speed, light-load, and low-temperature conditions; composite aluminum-based grease Disadvantages: the price is high, the bearing life is not long, the thickening ability of composite aluminum soap to mineral oil is relatively strong, but the thickening ability to synthetic oil, such as silicone oil, ester oil, PAG, etc. is very poor, and even does not form fat
A large amount of mineral oil is used in lubricating oil, but many occasions cannot meet the requirements of use
For example, mineral oil cannot meet the use requirements under high or ultra-low temperature, strong pollution environment, heavy load, etc.; the price of synthetic oil is high, so research and use new materials, improve the function of lubricating oil, meet the use requirements and save energy and protect the environment.

Embodiment 1

[0018] A kind of nanometer multifunctional lubricating oil, it is characterized in that, according to the mass ratio, it is composed of composite nanoscale additive 0.1%, detergent 3.2%, dispersant 4.3%, antioxidant 1.4%, high temperature antioxidant 1.0%, viscosity index improvement 5.5% additive, 0.5% pour point depressant, and the balance is made of base oil.

[0019] A method for making nanometer multifunctional lubricating oil. First, base oil is added to a reactor, and the agitator is turned on; Put the antioxidant into the base oil and start heating. After the temperature reaches 75°C, keep the temperature constant for 2 hours; add the composite nano-additive and dispersant into the reactor, continue to heat up to 120°C-160°C, and keep the temperature constant for 2 hours; it is the finished oil .

[0020] The stirrer adopts a high-speed stirrer or ultrasonic stirring.

[0021] After adding 0.1% mass fraction of composite nano-additives to ordinary lubricating oil, th...

Embodiment 2

[0023] A kind of nanometer multifunctional lubricating oil, it is characterized in that, according to the mass ratio, it is composed of composite nanoscale additive 0.15%, detergent 2.6%, dispersant 3.3%, antioxidant 1.5%, high temperature antioxidant 1.2%, viscosity index improvement 4.0% additive, 0.4% pour point depressant, and the balance is made of base oil.

[0024] The anti-wear and anti-friction mechanism of nanometer multifunctional lubricating oil is closely related to the type, structure, size and surface treatment materials of nanoparticles. The anti-wear and anti-friction mechanism of nanoparticles are:

[0025] 1. During the friction process, under the conditions of high temperature and high pressure, nanoparticles have strong adsorption force and form a deposited film on the friction contact surface, which can greatly improve the carrying capacity. Once the lubricating oil leaks, the deposited film on the contact surface can lubricate in an emergency.

Abstract

The invention discloses nano multifunctional lubricating oil, which is prepared from the following components by mass: 0.1-1.8% of a composite nano additive, 2.0-5.7% of a clearing agent, 3.2-6.6% ofa dispersing agent, 1.5-3.0% of an oxidation and corrosion inhibitor, 2.0-4.0% of a high-temperature antioxidant, 3.3-5.5% of a viscosity index improver, 0.2-1.0% of a pour point depressant and the balance base oil. The making method includes: firstly adding the base oil into a reactor, and starting a stirrer; then sequentially adding the viscosity index improver, the pour point depressant, the clearing agent, the dispersing agent, the oxidation and corrosion inhibitor and the high-temperature antioxidant into the base oil, starting heating, and keeping the temperature constant for 2h after the temperature reaches 75DEG C; adding the composite nano additive and the dispersing agent into the reactor, continuously performing heating to 120DEG C-160DEG C, and keeping the temperature constantfor 2-5h; thus obtaining the product oil. Compared with the prior art, the lubricating oil has the advantages of special tribological properties like wear resistance, friction reduction, high load capacity and self-repairing function in the aspects of lubrication and tribology, has no toxic or side effect in use, and is harmless to the environment and human bodies.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a nanometer multifunctional 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 some disadvantages of its own. For example, the disadvantages of calcium-based grease: poor heat resistance, the maximum operating temperature is 60 ° C; the disadvantages of sodium-based grease: general heat resistance, better than calcium-based grease, the general operating temperature is 80 ° C; general lithium-based grease Disadvantages of extreme pressure lithium-based grease: both have a maximum service temperature of 120°C; disadvantages of molybdenum disulfide extreme-pressure lithium-based grease: a maximum service temperature of 120°C, not suitable for high-speed, light-load, and low-temperature conditions; com...
