Abstract

The invention relates to the technical field of lubricating grease, in particular to low-noise lubricating grease suitable for micromotors and a preparation method of the low-noise lubricating grease. The method comprises the steps that base oil with different viscosities and types is adopted for blending, structure modifier is added, the lubricating grease forms a layer of better oil film on the contact surface of a workpiece, and the noise reduction effect is effectively achieved. Meanwhile, the lubricating grease is prepared by reacting compound base oil with compound thickening agents, and therefore the service life of the lubricating grease is effectively prolonged. According tot he lubricating grease prepared through the method, the technology is simple, and the production cost is low. When the lubricating grease is used in the micromotors, the surface of the workpiece can form a layer of effective protective oil film, the lubricating grease is not prone to runoff when the micromotors run at a high speed, the high-temperature resistance is good, and good effects of lubricating, noise reduction and rust prevention are achieved.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to low-noise lubricating grease suitable for micromotors and a preparation method thereof. Background technique [0002] Lubricating grease (lubricating grease, grease) is a kind of thick grease paste semi-solid, which is used in the friction part of machinery to lubricate and seal, and is also used on metal surfaces to fill voids and prevent rust. The working principle of grease is that the thickener keeps the oil in the position that needs to be lubricated, and when there is a load, the thickener releases the oil to lubricate. Grease is mainly prepared from mineral oil (or synthetic lubricating oil) and thickener. According to the thickener, grease can be divided into two types: soap-based grease and non-soap-based grease. Commonly used thickeners for soap-based greases include metal soaps such as lithium, sodium, potassium, calcium, aluminum, zinc, barium, lead, and ...
