Abstract

To provide a coating composition for a lubricating coating film capable of forming a lubricating coating film having a high level of flexibility on surfaces of various base materials. <Resolution Means> A coating composition for a lubricating coating film including: (A) a phenolic resin, (B) an epoxy resin having an epoxy equivalent weight of 600 to 4000, and (C) at least one type of solid lubricant; and having a weight ratio of component (A) to the total weight of component (A) and component (B) of at least 50 weight %.

Description

technical field [0001] The present invention relates to coating compositions for lubricating coating films. Furthermore, the present invention relates to a lubricating coating film obtained by curing a coating composition for a lubricating coating film, a sliding member provided with a lubricating coating film, and a method for manufacturing the sliding member. Background technique [0002] As described in, for example, Japanese Unexamined Patent Application Publication No. 2013-189569, a sliding member provided with a binder containing a phenolic resin and an epoxy resin and provided with a coating film containing a solid lubricant is known . [0003] However, in some cases, the above-mentioned coating film lacks flexibility, and in such cases, the adhesion between the substrate and the coating film may be impaired. For example, if the above-mentioned coating film is formed on the surface of a sheet-like substrate made of metal, the coating film is poor in flexibility, an...
