Abstract

The purpose of the present invention is to provide: a foreign substance removing lubricating composition which has high foreign substance removal effect, while having improved lubricity in comparisonto conventional foreign substance removing lubricating compositions; a member which is coated with this foreign substance removing lubricating composition; and a use of this foreign substance removinglubricating composition. A foreign substance removing lubricating composition according to the present invention is characterized by containing a perfluoroalkyl group-containing compound (S) having aperfluoroalkyl group or a fluoropolyether-containing compound. Consequently, this foreign substance removing lubricating composition is able to have enhanced foreign substance removal effect, while having improved lubricity in comparison to conventional foreign substance removing lubricating compositions.

Description

technical field [0001] The present invention relates to a foreign matter removing lubricating composition, a member coated with the foreign matter removing lubricating composition, and a method of using the foreign matter removing lubricating composition. Background technique [0002] Lubricating oil or grease is used in automotive parts such as door lock mechanisms, window regulators, seat rails, and sunroofs, as well as components with sliding parts in various equipment. [0003] However, there is a problem that when foreign substances such as dust and sand are mixed into lubricating oil or grease, not only the wear of the sliding member is promoted, but also abnormal noise may be generated in some cases. [0004] prior art literature [0005] patent documents [0006] Patent Document 1: Japanese Patent Laid-Open No. 2008-38047 Contents of the invention [0007] As a prior art, for example, it is known to improve lubricating performance by a grease composition added w...
