Abstract

The invention relates to the technical field of lubricating greases, in particular to low-noise lubricating grease suitable for a juicer and a preparation method of the lubricating grease. By adding a nanoscale material with a noise reduction effect and meanwhile adding a moderate amount of an additive in a process of synthetizing urea-based lubricating grease, the lubricating grease has excellent abrasion resistance and an extreme pressure property as well as excellent high temperature performance. Besides, different solid fillers with certain microwave absorbing properties are introduced into the lubricating grease, noise produced by irregular vibration during gear operation can be effectively lowered, and an effective noise reduction effect is achieved.

Description

technical field [0001] The invention relates to the technical field of lubricating grease, in particular to a low-noise lubricating grease suitable for a juicer and a preparation method thereof. Background technique [0002] Lubricating grease (lubricating grease, grease) is a thick, greasy semi-solid used for mechanical friction parts to lubricate and seal, and also used on metal surfaces to fill gaps 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. In the prior art, urea-based grease mainly uses diisocyanate and organic amine to react at 60-80°C, then keep warm at 130-200°C, then add extreme pressure anti-wear agent, antioxi...
