発明の名称 (英語) WATER-BASED LUBRICANT 新技術説明会
発明の概要(英語) Provided is a water-based lubricant that is water-based in order to resolve the problem of flammability, and in which the need for additives such as surfactants can be minimized to reduce the cost associated with processing the waste liquid after use. A water-based lubricant in which graphene oxide, obtained by performing a separation process on graphite and separating the graphene oxide from the graphite, is dispersed in water. The separation process causes the separation by the graphite being mixed into an aqueous solution containing an oxidation agent, and caused to oxidize. The graphite is a fine powder having an average grain size of 100 μm or less and contains graphene oxide at a concentration of 0.1wt% or above. If the average grain size of the graphite is 50 μm or less, the graphene oxide is contained at a concentration of 0.01 wt% or above.
