Abstract
The invention discloses low-temperature composite calcium sulfonate-based lubricating grease and a preparation method thereof, and belongs to the technical field of lubricating grease, wherein the low-temperature composite calcium sulfonate-based lubricating grease comprises the following raw materials in parts by weight: 35-40 parts of low-temperature base oil, 1.1-1.5 parts of a converting agent, 3.5-5.5 parts of a composite thickening agent, 25-30 parts of ultrahigh-base-number synthetic calcium sulfonate, 3.5-5.5 parts of monoalkyl titanate, 1.5-2.5 parts of micro-nano borate, 1.5-2.0 parts of glacial acetic acid, 1.2-1.8 parts of cyclohexylamine, 0.5-1.5 parts of a high-temperature antioxidant, 1.0-2.0 parts of an oxidation and corrosion-resistant additive and 0.1-3.5 parts of a surfactant. By blending the low-temperature base oil, the low-temperature resistance of the lubricating grease can be improved from the raw materials, and by adding the oxidation and corrosion-resistant additive, the oxidation resistance and the corrosion resistance of the lubricating grease can be improved, so that the service life of the lubricating grease is prolonged, and the lubricating grease issuitable for popularization and application.
