Abstract

The invention provides lubricating grease for an industrial robot. The lubricating grease is prepared from base oil, a tetrapolyurea-composite calcium sulfonate thickener, an antioxidant, a solid additive, an extreme-pressure anti-wear agent, an antirust agent and an anti-foaming agent. The invention further provides a preparation method of the lubricating grease for the industrial robot. The lubricating grease of the invention is mostly remarkably characterized by very long high-temperature service life, very low friction coefficient, capability of improving the transmission efficiency of a speed reducer and reducing energy consumption, excellent fretting wear resistance, as well as excellent extreme-pressure wear resistance, water resistance, shearing resistance, rust prevention and stability. In addition, the production and preparation process of the lubricating grease is simple, and the product is environment-friendly and stable in quality.

Description

technical field [0001] The invention belongs to the field of petrochemical industry and relates to a lubricating grease, in particular to a lubricating grease for industrial robots and a preparation method thereof. Background technique [0002] Industrial robots were born in the 1960s. They are high-tech integrated with computer, cybernetics, mechanism, information and sensing technology, artificial intelligence, bionics and other disciplines. In recent years, ensuring personal safety, reducing labor intensity, improving large-scale production efficiency and quality reliability, reducing production costs, and the need for industrial upgrading have become the driving force for China's manufacturing industry to replace labor with industrial robots, and it has also promoted my country's industrial robots. Rapid growth of applications. my country has been the world's largest industrial robot market for five consecutive years, and it will continue to rise in the future. Accordin...
