PURPOSE:To obtain the titled lubricant having high dispersion stability, forming little precipitate and having improved adhesivity and fixability to metallic materials such as iron alloy, Ni-Cr alloy, etc., by reacting powdery quick lime, an alkali metal salt of a higher fatty acid and water. CONSTITUTION:The objective lime soap lubricant is produced by reacting (A) powdery quick lime usually containing >=98% calcium oxide with (B) an alkali metal salt of usually 12-24C (un)saturated higher fatty acid (e.g. beef tallow fatty acid sodium salt) and (C) water usually for 2-3hr under agitation while cooling the system to <=100 deg.C (preferably keeping the system at about 80 deg.C). |
