Abstract

The invention discloses an anti-ultraviolet and anti-discoloration lubricating grease. The lubricating oil comprises the following components in parts by weight: 140-170 parts of base oil, 10-15 partsof lithium hydroxide, 10-15 parts of fatty acid, 3-5 parts of graphite, 3-5 parts of molybdenum disulfide, 3-5 parts of carbon black, 3-5 parts of glycerol, 2-4 parts of an antioxidant, 2-4 parts ofan ultraviolet light absorber, 2-4 parts of a light stabilizer, 2-4 parts of a high-temperature-resistant additive, 10-20 parts of water and 2-4 parts of a defoaming agent. The anti-ultraviolet and anti-discoloration lubricating grease can strongly absorb ultraviolet rays with the wavelength of 290-400 nm and effectively prevent oxidation and discoloration of the lubricating grease, the light stabilizer, the antioxidant and the ultraviolet absorber are used together, an excellent synergistic effect is achieved, the anti-ultraviolet performance of the lubricating grease is further improved, andthe high-temperature resistance of the lubricating grease is greatly improved; the problem that the color of the lubricating grease is deepened due to high temperature is avoided, the deterioration of the lubricating grease is effectively prevented, the thickening capacity to the base oil is high, the consumption of lithium hydroxide and fatty acid is reduced, the thickening effect on the base oil is guaranteed, and the service life of the lubricating grease is prolonged.

Description

Technical field[0001]The invention relates to the technical field of lubricating grease, in particular to an anti-ultraviolet and anti-tarnishing grease.Background technique[0002]Lubricating grease is a thick grease-like semi-solid. It is used for the friction part of the machine for lubrication and sealing. It is also used for metal surfaces to fill gaps and prevent rust. It is mainly made of mineral oil and thickening agent. Grease can adhere to the vertical surface without loss at room temperature, and can work in open or poorly sealed friction parts, and has a holding point that other lubricants cannot replace.[0003]Grease can maintain its shape without flowing, and can adhere to metal without slipping. When high temperature or external force exceeds a certain limit, it can flow like a liquid. Grease is sheared by moving parts in machinery. When the shearing action, it can produce flow and lubricate, reduce the friction and wear between the moving surfaces, when the shearing act...
