Publication number: 20150315512Abstract: A water-based coolant contains: at least one inorganic acid salt selected from among carbonate, hydrogen carbonate, sesquicarbonate, phosphate, borate, molybdate and tungstate; and a metal corrosion inhibitor. The water-based coolant is excellent in cooling performance and unlikely to cause corrosion of a metal material to be cooled. Therefore, the water-based coolant is suitably usable as a quenchant or a cutting oil.Type: ApplicationFiled: December 10, 2013Publication date: November 5, 2015Applicant: IDEMITSU KOSAN CO., LTD.Inventors: Mayu HASEGAWA, Masahisa GOTO, Katsumi ICHITANI, Kenro NOGUCHI

Publication number: 20150000710Abstract: A water-based coolant contains at least one inorganic acid salt of phosphate, phosphite, sulfate, sulfite, borate, molybdate, tungstate, carbonate, hydrogen carbonate and sesquicarbonate. Since the water-based coolant of the invention exhibits a high cooling capability but does not easily corrode a metallic material (a cooling object), the water-based coolant of the invention is suitable as a quenching oil or a cutting oil for the metallic material.Type: ApplicationFiled: February 27, 2013Publication date: January 1, 2015Applicant: IDEMITSU KOSAN CO., LTD.Inventors: Mayu Hasegawa, Masahisa Goto, Katsumi Ichitani, Kenro Noguchi
