Problems solved by technology

Therefore, the temperature has a great influence on the use state of the grease during the use of the grease, and the existing grease has poor high temperature resistance, and it is difficult to maintain the consistency and adhesion when the use temperature is too high, resulting in poor lubrication effect , not only will consume too much energy when overcoming the frictional force, but also will wear the internal components of the bearing, affecting the use

Abstract

High-temperature resistant lubricating grease for bearings and a preparing method thereof are disclosed. A dielectric layer is prepared from polytetrafluoroethylene, agar, pentaerythritol, sulfosuccinate, polyphenyl ether, polyacrylamide, silicon oxide, calcium silicate and molybdenum disulfide. The method includes crushing, homogenizing, heating, mixing, stirring, cooling, grinding, filtration and filling steps. The lubricating grease has high resistance to high temperatures, can have high consistence and adhesive force in a high-temperature environment, and has good lubricating effects in ahigh-temperature environment. The preparing method is simple and the production cost is low.

Description

technical field [0001] The invention relates to a bearing lubricating grease, in particular to a bearing high temperature resistant lubricating grease and a preparation method thereof. Background technique [0002] Grease English name: lubricating grease; grease thick grease like semi-solid. It is used in the friction part of the machine to lubricate and seal. It is also used on metal surfaces to fill voids and prevent rust. [0003] The function of grease is mainly to lubricate, protect and seal. The vast majority of greases are used for lubrication and are called antifriction greases. Anti-friction grease mainly plays the role of reducing mechanical friction and preventing mechanical wear. At the same time, it also plays a protective role against metal corrosion and a sealing and dustproof function. There are some greases that are primarily used to prevent rust or corrosion of metals, called protective greases. [0004] It is in a paste state at room temperature and ...
