Environment-friendly wide-temperature water and rust-resistant rail top lubricating grease composition

Abstract

The present invention discloses an environment-friendly wide-temperature water and rust-resistant rail top lubricating grease composition which is prepared by mixing base oil and a variety of complex additives, the base oil is obtained by compounding 90%-70% by mass of MVI300 base oil and 10%-30% of poly alpha olefin , and the variety of complex additives includes butter, castor base, rapeseed oil, calcium hydroxide, sodium hydroxide, flaky graphite, an antioxidant preservative, an antioxidant, an anti rust agent, an extreme pressure agent, an antiwear agent and the like. The composition has the advantages of use stability in a wide temperature range, good pumping performance and adhesion, good expansion ability, excellent extreme pressure abrasion resistance, water resistance, rust resistance and antioxidation stability.

Description

technical field [0001] The invention relates to an environment-friendly, wide-temperature, water-resistant, rust-proof rail top lubricating grease composition, which belongs to the field of lubricating greases. Background technique [0002] As a heavy passenger and freight job, railways are related to the national economy and the people's livelihood. Materials that need to be transported in large quantities include petroleum, coal, steel, mineral raw materials, and agricultural and sideline products. They play an irreplaceable role in logistics transportation, especially coal and ore. . Coal accounts for more than 60% of my country's energy consumption and has always been an important component of railway transportation. With the operation of 10,000-ton heavy-duty trains and the increasing axle load of trucks, the dynamic interaction between vehicles and rails has become more and more severe, and the wear of wheel and rail has become more and more serious, resulting in poor...
