Abstract

[Problem] To provide a water-based lubricating coating agent for a metal material, said coating agent making it possible to realize excellent lubrication properties even during plastic working, pressmolding etc., making it possible to simultaneously solve operability (process shortening, sludge reduction etc.), and making it possible to simultaneously carry out chemical conversion treatment and lubrication treatment. [Solution] Provided is a water-based lubricating coating agent for a metal material, said coating agent having a pH of 2.0-6.5 and being formed by blending at least one type of lubricating component other than a black solid lubricating agent and at least one type of chemical conversion component selected from the group consisting of a phosphoric acid compound, oxalic acid compound, molybdic acid compound, zirconium compound, and titanium compound, said coating agent being characterized in that the concentration of the lubricating component is at least 5 mass% by mass ratio relative to the mass of the total solid content in the lubricating coating agent, and the concentration of the chemical conversion component is 0.3-8 mass% when the total mass of the lubricating coating agent is defined as 100 mass%.

Description

technical field [0001] The present invention relates to an aqueous lubricating coating agent for metal materials which can form a lubricating coating with a two-layer structure of a lower layer as a chemical conversion coating and an upper layer as a lubricating coating on the surface of metal materials, particularly metal materials such as steel, stainless steel, aluminum, and magnesium, in one step, and related technologies. More specifically, the present invention relates to a lubricating coating agent used for plastic working such as forging, wire drawing, pipe drawing, and punching, press forming of sheet materials, sliding parts of various devices, etc. Contains black lubricants such as molybdenum disulfide or graphite. Background technique [0002] Generally speaking, when plastic working of metal materials, for the purpose of preventing ablation (焼付き) and galling (galling, かじり) caused by the metal contact between the workpiece and the tool, a metal material with a ...
