Abstract
Provided is an anti-wear agent capable of furnishing an epoxy resin coating film with anti-wear properties. The anti-wear agent is characterized by containing an alicyclic difunctional epoxy and a polymerization initiator or is characterized by containing a difunctional bisphenol A-type epoxy resin, a leveling agent and a polymerization initiator.
Description
technical field [0001] The present invention relates to an anti-wear agent, and more particularly relates to an anti-wear agent capable of providing an epoxy resin coating having anti-wear properties. Background technique [0002] Conventionally, in internal combustion engines of ships, vehicles, and the like, sliding members are used in various devices. For such sliding parts, energy loss is reduced by reducing the coefficient of friction, and various developments are being made to meet the US Corporate Average Fuel Economy (CAFE) regulations to protect the global environment. [0003] For this reason, various developments have been made as sliding parts. Among them, a diamond-like carbon film-based sliding part using a diamond-like carbon film (DCL) as a coating has been proposed as a sliding part having good wear resistance. [0004] For example, Japanese Patent Application Laid-Open No. 7-41779 describes a sliding part that has a solid lubricant coating formed of a diam...
