Abstract

The invention discloses a high-temperature chain lubricating grease. The high-temperature chain lubricating grease comprises the following components in percentage by weight: 60-80% of base oil, 10%-20% of polytetrafluoroethylene lubricating particle additive, less than 8% of high-temperature anti-oxidation additive, less than 1% of anti-corrosion additive, less than 10% of high-temperature cleaning additive and 2%-8% of extreme pressure anti-wear additive. Compared with the traditional high-temperature chain lubricating grease, the high-temperature chain lubricating grease is low in residual carbon, non coking and capable of keeping a chain run stably for a long time, excellent in lubricity and abrasion resistance, good in adhesion, prone to form an oil film and long in service life, and extremely high in high-temperature bearing capability and high-speed anti-shear ability, and thus being enabled to rise to the occasion in a high-temperature environment.

Description

technical field [0001] The invention relates to a lubricating grease, in particular to a high-temperature chain lubricating grease. Background technique [0002] High-temperature chain grease is widely used in the lubrication and protection of high-temperature chains such as high-temperature ovens, ovens, spraying lines, and baking lines. In addition, it is also widely used in lubricating the chains and bearings of various machinery with high speed working at high temperature such as stretch tenter, hot melt fan, heat setting dryer, baking machine, high temperature dyeing vat, etc. . [0003] The current high-temperature chain grease still has deficiencies in maintaining long-term chain stability, lubricity, wear resistance, adhesion, etc., and cannot meet the lubrication requirements of high-temperature chains in extremely high-temperature environments. Contents of the invention [0004] The object of the present invention is to solve the above problems and provide a hi...
