Lithium-based lubricating grease composition and preparation method thereof

Abstract

The invention discloses a lithium-based lubricating grease composition and a preparation method thereof, and belongs to the technical field of lubricating grease. The composition is specifically composed of the following components in parts by weight: 83.5-90.0 parts of base oil, 5.0-7.5 parts of dodecahydroxyl stearic acid, 3.0-5.5 parts of stearic acid, 0.3-0.5 parts of naphthenic acid, 0.2-0.5parts of alkyl salicylic acid, 1.3-2.1 parts of lithium hydroxide and 0.2-0.4 parts of an antioxidant. The invention also provides a preparation method of the lithium-based lubricating grease composition. The prepared lithium-based lubricating grease is white and transparent in appearance, has the characteristic of low noise, and can meet the lubricating requirements of precise instruments, meters, electric tools, household appliances and other equipment.

Description

Technical field

[0001] The present invention relates to the technical field of grease, and more specifically to a lithium-based grease composition and a preparation method thereof. Background technique

[0002] Grease is a solid or semi-solid lubricant, generally composed of base oil, thickener and additives. It can adhere well to the surface of friction parts of mechanical equipment, thereby reducing friction and wear. Lithium-based grease is currently the most widely used grease, accounting for about 70% of my country's grease production.

[0003] Due to the shortcomings of conventional industrial lithium-based greases such as opaque appearance, dark color, and high noise, their use in precision instruments, meters, power tools, household appliances, robots, etc. is greatly restricted.

[0004] The existing research mainly focuses on improving the lubrication effect of grease, and there are few research reports on the appearance, color and low-noise performance of grease....
