水溶性金属加工用油剤

Japanese Patent JP4121644

B2

PROBLEM TO BE SOLVED: To provide a water soluble metal processing oil agent exhibiting excellent lubricity, surface property and rust preventive property without adding a chlorine-based or a sulfur-based extreme pressure. SOLUTION: This water soluble metal processing oil agent contains (a) 2-20 pts.wt. of at least one kind selected from polypropylene glycol or polybutylene glycol having 800-5,000 average molecular weight and (b) 1-15 pts.wt. of dibasic acid in 100 pts.wt. of the total agent. The metal processing oil agent exhibits excellent rust preventive property and can exhibit excellent lubricity without adding an extreme pressure additive. Therefore, a trouble caused by occurrence of rust in a processed product or a processing machine can be avoided. An improvement of a processing efficiency can be contrived by making a processing speed higher. Furthermore, a state generating a harmful combustion gas can be avoided in an incineration treatment of a waste liquid of an oil agent added with a chlorine-based or a sulfur-based additive.
