Abstract

The invention discloses an environment-friendly anti-rust oil composition for bearings. The environment-friendly anti-rust oil composition comprises the following components in percentage by weight: 2%-8% of petroleum calcium sulfonate, 0.5%-8% of oxidized paraffin calcium soap, 0.5%-3% of oleoyl sarcosine tallow amine salt, 1%-4% of a film-forming agent and the balance of machine oil. The anti-rust oil composition disclosed by the invention has good wettability and blocking property, has excellent damp-heat resistance and salt fog protection resistance on bearings of high-carbon alloy steel, copper alloy or steel and copper assemblies, has good sweat corrosion resistance, does not contain a volatile hydrocarbon compound, or barium and other heavy metals, and is good in environmental protection capability and safe to use. According to the environment-friendly anti-rust oil composition for the bearings disclosed by the invention, a film layer is good in protective performance and long in protective cycle, and especially has excellent damp-heat resistance and salt fog protection resistance on high-carbon bearing steel materials and bearing steel / copper alloy bearing assemblies; the anti-rust oil film has good sweat corrosion resistance; and the oiled bearings have good anti-pollution and anticorrosion properties.

Description

technical field [0001] The invention relates to an environment-friendly antirust oil composition for bearings, which belongs to the field of metal protection. Background technique [0002] Bearings are important mechanical components. Bearing rings and rollers are mainly bearing steel with high carbon content, and bearing cages are mainly made of steel or copper alloy. Bearing steel with high carbon content has high mechanical strength and wear resistance, but this material has high carbon content. In the metallographic structure, due to the chemical potential difference between iron carbon compound and iron, there is a chemical potential difference. Electrochemical corrosion is prone to occur in the atmospheric environment and the salty marine atmospheric environment. For bearings with a copper alloy cage, there is also a chemical potential difference between the cage and the rollers and rings made of bearing steel, and electrochemical corrosion is also prone to occur in ...
