Synthetic high-temperature lubricating grease and production method thereof

Abstract

The invention discloses a synthetic high-temperature lubricating grease and a production method thereof. The synthetic high-temperature lubricating grease is produced by taking synthetic oil as base oil and mixing the base oil with thickening agents, an extreme-pressure additive, an antioxidant and an anticorrosive agent, wherein the weight ratios of all ingredients are as follows: 47-94% of base oil, 2-20% of polyurea thickening agent, 2-20% of acylamide thickening agent, 0.5-5.0% of antioxidant, 1.0-5.0% of extreme-pressure additive and 0.5-3.0% of anticorrosive agent. In the invention, the synthetic base oil, the polyurea thickening agent and the acylamide thickening agent all have excellent high-temperature performance, and the organic combination thereof leads the lubricating grease to obtain excellent high-temperature performance; the polyurea thickening agent endows the lubricating grease with good colloid stability, and the acylamide thickening agent endows the lubricating grease with excellent anti-shear stability, therefore, the organic combination of colloid stability and anti-shear stability leads the lubricating grease to have excellent high-temperature performance and good losing resistance, does not change to thin and avoids losing at high temperature. The extreme-pressure anti-wear additive endows the lubricating grease with excellent extreme-pressure anti-wear performance, and the bearing capacity is high.

Description

Technical field: [0001] The invention relates to a lubricating grease composition, in particular to a synthetic lubricating grease with synthetic oil as base oil and polyurea and amide salt mixed thickener. Background technique [0002] With the rapid development of industries such as metallurgy, mining, building materials, petrochemicals, machinery manufacturing, food processing, textile printing and dyeing, and papermaking, the load requirements of bearings in these industries are increasing, and the temperature requirements are increasing. Traditional high-temperature grease In use, it cannot meet the requirements of use, and the phenomenon of thinning, loss and coking and carbonization often occurs, resulting in the scrapping of bearings. In production, a lubricating grease with suitable high temperature performance and good extreme pressure and anti-wear properties is extremely needed to reduce the scrapping rate of bearings. , to ensure the smooth progress of productio...
