Abstract

The present invention provides a lubricant surface treatment agent capable of improving the foreign matter removal effect of lubricants and improving lubricity compared with the prior art, a foreign matter removal lubricating composition and a foreign matter removal lubricating composition using the lubricant surface treatment agent. A method of producing a lubricating composition, a member coated with the foreign matter removing lubricating composition, and a method of using the foreign matter removing lubricating composition. The lubricant surface treatment agent in the present invention is characterized by containing at least one of a perfluoroalkyl-containing compound having a perfluoroalkyl group or a fluorine-containing polyether compound.

Description

technical field [0001] The present invention relates to a lubricant surface treatment agent, a foreign matter removing lubricating composition, a method for producing the foreign matter removing lubricating composition, a member coated with the foreign matter removing lubricating composition, and a method for using the foreign matter removing lubricating composition. Background technique [0002] Lubricating oil or grease can be used on 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, when foreign matter such as dust or sand is mixed into lubricating oil or grease, there are problems in that wear of sliding members is accelerated and abnormal noise may be generated in some cases.
