Abstract

The invention relates to the field of lubricating materials, in particular to a valve core sealing lubricating agent composition, which comprises: (A) 100.0 weight parts of base oil; (B) 5.0 to 35.0 weight parts of thickening agent; (C) 3.0 to 55.0 weight parts of solid lubricating agent; (D) 0.1 to 3.0 weight parts of surfactant; (E) 0.1 to 2.5 weight parts of antioxygen; (F) 0.1 to 4.0 weight parts of extreme pressure antiwear agent; (G) 0.1 to 2.0 weight parts of metal passivating agent; and (H) 0.1 to 1.5 weight parts of antimicrobial agent. The finished lubricating agent prepared according to the mixing ratio has high high-temperature resistance, high antiwear and wear-resistance performance and high dead-locking-preventing performance. Meanwhile, the production and preparation method of the lubricating agent are simple, convenient and easy to implement and is suitable for large-scale batch production.

Description

technical field [0001] The invention belongs to the field of lubricating materials, and in particular provides a valve core sealing lubricant composition. Background technique [0002] Lubricants are semi-solid (or semi-fluid) materials made by dispersing thickeners in liquid lubricating oils, and other components that impart certain special properties can also be added. It has a wide range of uses, and all kinds of lubricating grease are required for the parts that rotate and slide to lubricate the mechanical friction parts. At the same time, in some applications, grease is often required to have functions such as waterproof, dustproof, rustproof and sealing protection. [0003] In the mechanical field, the spool, as a valve part that uses its movement to realize the basic functions of direction control, pressure control or flow control, has a wide range of applications. There are also many grease products used in conjunction with it. However, with the development and pr...
