Abstract

The invention relates to superstrong extreme pressure antiwear lubricating grease and a preparation method thereof; particularly, a densifier is generated by calcium sulfonate with a high base number through a phase inversion reaction, and the lubricating grease is prepared by combining base oil with other functional additives, wherein the base oil is combined by base oil with high viscosity and medium viscosity. The method comprises the following steps: stirring and mixing the composite base oil and the calcium sulfonate in a reaction vessel, heating, adding a phase inversion promoter, glacial acetic acid, and water, heating and reacting at a constant temperature, adding calcium hydrate, aliphatic acid and boric acid after the phase inversion is completed, reacting at a constant temperature, heating and dehydrating, adding an anti-oxidant, refining, transferring the materials into a blending vessel, adding an eutectic rolling additive and an adhesion improver, dispersing and homogenizing the mixture, filtering, and degassing to obtain the finished product. The lubricating grease of the invention has excellent water sprinkling resistance, excellent high and low temperature performance, superstrong extreme pressure antiwear performance, excellent pumping performance, outstanding shearing stability, and antirust performance.

Description

technical field [0001] The invention relates to a multifunctional ultra-extreme pressure anti-wear grease and a preparation method thereof, which are widely used in places where the grease is used in harsh environments such as mines, steel, cement, and electric power. Background technique [0002] Mining, steel, cement, electric power and other enterprises have a lot of equipment with very harsh working environment. Some of them are under long-term heavy-duty work, some have more dust, some work in high temperature and humidity for a long time, and some are washed by water for a long time. These high temperature, Harsh conditions such as water, dust, and heavy loads have a greater impact on equipment bearings and other parts, resulting in huge consumption of lubricating materials and replacement costs for spare parts. Therefore, the performance of lubricating grease used in such equipment bearings is also proposed. higher requirements. [0003] The furnace mud cannon and ca...
