Composition of compound calcium sulfonate-based lubricating grease for improving high-temperature performance and preparation method thereof
InactiveCN104327906AGood high temperature resistanceImprove retentionThickenersTemperature resistanceSalicylic acid
The invention relates to a composition of compound calcium sulfonate-based lubricating grease for improving high-temperature performance and a preparation method thereof. The composition is prepared from a high-alkalinity calcium sulfonate cleaner, methanol, lithium hydroxide, salicylic acid, C12-C16 salicylic acid and base oil. The lubricating grease provided by the invention has relatively good high-temperature resistance and meets the seepage loss of ASTM D4290 and ASTM D1263 (industrial standard is SH / T0326). Experiments show that the seepage loss ranges from 5 to 10 which is obviously better than that (15-35g) of marketed products. The improving method provided by the invention can be used for prolonging the retentivity of the lubricating grease in a friction pair so as to ensure the operating reliability of equipment.
