Lubricating oil composition for oil film bearing

Abstract

The invention discloses a lubricating oil composition for an oil film bearing. The lubricating oil composition is characterized by being prepared by stirring the following raw materials in percentage by weight for 5 hours at 60-90 DEG C: 93-95% of high-viscosity-index refined mineral oil, 0.1-0.9% of fatty acid polyol ester, 0.01-0.1% of polyglycerol ether, 1.0-4.0% of dibatyl dithio-formamide, 0.1-1.0% of thiophosphate and 0.1-1.0% of a benzotriazole fatty acid salt. The lubricating oil composition disclosed by the invention has excellent hydrous wear resistance and wear-resistant durability to guarantee good wear resistance under the condition with water, can be used for quickly separating oil and water in a static state to ensure that the content of water in the lubricating oil does not exceed a standard, and has excellent thermal oxidation stability to ensure that an oil product has a relatively long service life.

Description

technical field [0001] The invention relates to a lubricating oil composition, in particular to an oil film bearing lubricating oil composition. Background technique [0002] The use of bearings on industrial machinery generally has the characteristics of high working environment temperature, complex transmission, high precision, fast speed and heavy load. Oil film bearing lubricating oil will inevitably enter industrial water during use, so oil film bearing lubricating oil is required It still has good anti-wear properties under the condition of static, and quickly separates oil and water under static conditions to ensure that the water content in the lubricating oil does not exceed the standard. Due to the special requirements of lubricating oil for oil film bearings, it brings difficulties to the production technology of lubricating oil for oil film bearings. Under such harsh working conditions, oil film bearing lubricants require oil film bearing lubricants to put forwar...

[0002] The use of bearings on industrial machinery generally has the characteristics of high working environment temperature, complex transmission, high precision, fast speed and heavy load. Oil film bearing lubricating oil will inevitably enter industrial water during use, so oil film bearing lubricating oil is required It still has good anti-wear properties under the condition of static, and quickly separates oil and water under static conditions to ensure that the water content in the lubricating oil does not exceed the standard. Due to the special requirements of lubricating oil for oil film bearings, it brings difficulties to the production technology of lubricating oil for oil film bearings. , oil film bearing lubricating oil under such harsh working conditions requires oil film bearing lubricating oil to put forward higher requirements in water separation performance, extreme pressure and anti-wear performance, and develop an oil film bearing lubrication with high water separation performance and extreme pressure and anti-wear performance Oil products are very necessary
