The present invention relates to a composition solution. Elements of the composition have a lubricant effect, a cooling effect, cutting chip generating and eliminating properties, and rust-resistant properties, which are properties unique to water-soluble cutting oil. The composition solution includes at least one metal ion of tungsten, molybdenum, silicon, magnesium, vanadium, zirconium, titanium, and hafnium which are eco-friendly and have excellent durability, corrosion resistance, and heat resistance. The composition is produced by mixing and reacting fluoride as an etching agent for a metal surface, a silane coupling hydrolyzate enhancing adhesiveness, and copper ions as metal catalysts. The composition prevents formation of heavy metal sludge, formed in an existing pretreatment process; phosphate, factors for eutrophication of river and water streams, is not used for the composition solution. Therefore, the composition solution is eco-friendly. |
