Title:
Metal processing liquid which does not contain amine and does not contain VOC
Document Type and Number:
Japanese Patent JP5968428
Kind Code:
B2
Abstract:
The present application concerns an aqueous metalworking composition comprising in a concentrate or after dilution of a concentrate with water in a diluent: 0.002 to 40% by weight of component (a) which is a lubricity agent comprising at least one water-insoluble compound (a) having at least one hydrophobic aliphatic chain and at least one polar group and having a water solubility at 20° C. of less than 0.1 g/liter; 0.002 to 40% by weight of component (b) comprising at least one water-soluble corrosion inhibiting compound (b) having a water-solubility at 20° C. of more than 0.1 g/liter; 0.002 to 45% by weight of at least one emulsifying and dispersing agent (c) which contains at least one emulsifying and/or dispersing compound (c) which is water-soluble, water-miscible or water-dispersable and which is selected from the group consisting of non-ionic, anionic and zwitterionic surfactants; 0.002 to 30% by weight of an alkalinity agent (d) containing at least one alkaline water-soluble compound (d) selected from the group consisting of hydroxides and carbonates; and 0.004 to 99% by weight of a transport component (e) containing predominantly water. Further on, the present application concerns a method of use of such aqueous metalworking composition as a coolant, as a lubricant, etc., and concerns further on a method to prepare an aqueous metalworking composition and a metalworking process.
