Patent ID: 8288325

Claim:
A lubricant composition for hot forming comprising: solid lubricant from 10 to 40% by mass; water-dispersible synthetic resin from 5 to 20% by mass; inorganic acid amine salt from 0.5 to 5% by mass, the inorganic acid of said inorganic acid amine salt being selected from boric acid, molybdenum acid, or tungsten acid; and water from 45 to 80% by mass, for 100% by mass of the total mass of the lubricant composition, wherein said water-dispersible synthetic resin is a resin obtained by polymerization with the following a first to a fourth ingredients, a first ingredient: main monomer from 85 to 99.7% by mass, a second ingredient: monomer having functioning group from 0.1 to 7% by mass, a third ingredient: cross-linking monomer from 0 to 5% by mass, a fourth ingredient: co-polymeric surfactant from 2.1 to 7% by mass, for 100% by mass of the total mass of said first to fourth ingredients, said main monomer is two or more monomers selected from methacrylic ester or acrylic ester, and solubility of said monomer in the water is 1% or less.
