LUBRICANT COMPOSITION FOR HOT FORMING

摘要

Disclosed is a lubricant composition for hot forming which contains 10-40 mass% of a solid lubricant, 5-20 mass% of a water-dispersible synthetic resin, 0.5-5 mass% of an amine salt of an inorganic acid, and 45-80 mass% of water. Such a lubricant composition for hot forming exhibits lubricating properties without being separated or washed away by roll cooling water at temperatures not less than 80˚C, while it does not have water resistance at temperatures less than 40˚C and thus can be easily cleaned away by water.
