Abstract
The invention discloses an ionic liquid-based conductive lubricating grease, which is composed of ionic liquid and lithium-based lubricating grease / polyurea lubricating grease at a mass ratio of 0.1-10% and 90-99.9%. After testing, the ionic liquid-based conductive grease of the present invention has good electrical conductivity (resistivity between 3.07 and 11.71GΩ at a voltage of 10-30V) and lubricating grease (coefficient of friction is 0.1-0.13), which can be used in Machinery, aviation, aerospace and other fields.
Description
technical field [0001] The invention relates to an ionic liquid lubricating grease, in particular to an ionic liquid-based conductive lubricating grease, which belongs to the field of lubricating grease. Background technique [0002] The main function of lubricating grease is lubrication and protection, and the lubricating grease used in the conductive parts of electrical equipment, in addition to lubricating and protective properties, its good electrical conductivity is also one of the important indicators. The use of conductive grease can reduce wear and wear while enhancing the electrical conductivity of contacts and equipment, thereby reducing equipment corrosion, preventing static electricity accumulation and causing arcs to cause problems such as ablation of balls and pitted raceways. In the early days of the development of conductive grease, people generally increased the conductivity of the grease by adding components such as molybdenum disulfide to the base oil. La...
