LUBRICANT COMPOSITION AND LUBRICANT COMPOSITION-COVERED METAL SHEET

摘要

Provided is a lubricant composition and a lubricant composition-covered metal sheet excellent in degreasing property corrosion resistance, and moldability of a metal sheet.;The lubricant composition of the invention comprises a paraffin wax, a liquid paraffin, and a sorbitan fatty acid ester, with a content of the liquid paraffin relative to 100 parts by mass of the paraffin wax being 10-500 parts by mass; an HLB value of the sorbitan fatty acid ester being more than 0 and 4.5 or less; and a content of the sorbitan fatty acid ester relative to 100 parts by mass of total of the paraffin wax and the liquid paraffin being 5-30 parts by mass. The sorbitan fatty acid ester preferably has a sorbitan having only a part of hydroxyl groups thereof esterified. The lubricant composition preferably further comprises a polyoxyethylene alkyl ether which preferably has an HLB value of 10-20.
