Title:
WATER-SOLUBLE LUBRICANT FOR WARM OR HOT PLASTIC WORKING
Document Type and Number:
Japanese Patent JP3665745
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water-soluble lubricant for warm or hot plastic working, which is excellent in lubricity and mold release properties, can control the deposition of a metal, and does not worsen the working environment and the operating efficiency.
SOLUTION: The lubricant contains an anionic polymer compound having an average molecular weight of 500 to 1,000,000 and a nonionic polymer compound having an average molecular weight of 500 to 1,000,000, with the contents of the anionic polymer compound and the nonionic polymer compound respectively being 0.5-50 wt.% and 0.2-30 wt.% based on 100 wt.% of the lubricant. The anionic polymer compound preferably comprise polymer having at least one of a sulfo group and its ion group, and a carboxy group and its ion group.
