Nano graphite fluoride lubricant oil and preparation method therefor

Abstract

The invention discloses nano graphite fluoride lubricant oil and a preparation method therefor. The nano graphite fluoride lubricant oil is prepared from the following ingredients in parts by weight:250-350 parts of base oil, 10-15 parts of detergent, 5-18 parts of dispersant, 3-10 parts of foam inhibitor, 5-15 parts of viscosity index improver, 15-30 parts of nano graphite fluoride, 1-2 parts ofemulsifier, 10-25 parts of extreme-pressure antiwear additive, 2-5 parts of pour point depressant and 3-9 parts of alcohols. According to the nano graphite fluoride lubricant oil prepared by the preparation method, a layered structure of the nano graphite fluoride is prone to sliding, the friction factor is small, and thus, the nano graphite fluoride lubricant oil has an excellent lubricating property. The graphite fluoride is highly stably dispersed in lubricant oil, is uniform in dispersion, is of a nanometer scale, is very small in particle size, easily enters a friction area and will deposit on a microscopic friction area of a worn-out surface under pressure to exert a self-repairing action, so that the nano graphite fluoride lubricant oil has excellent extreme-pressure and antiwear properties, can adapt to harsh environmental conditions such as high temperatures and extreme pressure and is environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of lubricating oil, in particular to a nanometer fluorinated graphite lubricating oil and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of modern industrialization, the requirements for mechanical structure design and service life have been continuously improved. At the same time, the requirements for the operating environment have become more and more stringent, and the awareness of environmental protection has increased, so that the lubricating oil needs to be more excellent. comprehensive performance. Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil. Additives can make up for and improve the performance of base oil, endow some new properties, and are an important part of lubricating oil. The mineral-based lubr...

Problems solved by technology

[0005] To sum up, the traditional mineral-based lubricating oils have reduced lubricity under conditions of high temperature and extreme pressure, and have great wear on friction pairs, making it difficult to meet the requirements of use, and nano-materials are prone to agglomeration in the base oil, making the lubricating effect poor.
