Abstract
The present invention provides a lubricant composition for hot forming which makes it possible to provide lubricity at 80° C. or more without being peeled or washed by the roll cooling water, and which is easily washed under 40° C. without having water resistance. The lubricant composition for hot forming of the present invention comprises: a 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; and water from 45 to 80% by mass.
Claims8
A lubricant composition for hot forming comprising:
- a solid lubricant from 10 to 40% by mass;
- a water-dispersible synthetic resin from 5 to 20% by mass;
- an inorganic acid amine salt from 0.5 to 5% by mass;
- 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 vinyl acetate polymer obtained by emulsion polymerization using protective colloid selected from a group consisting of hydroxyethyl cellulose, sodium salt of carboxymethyl cellulose, and ammonium salt of carboxymethyl cellulose, or a vinyl acetate polymer obtained by emulsion polymerization using co-polymeric surfactant, and
- the inorganic acid of said inorganic acid amine salt is selected from boric acid, molybdenum acid or tungsten acid.
A lubricant composition for hot forming comprising:
- solid lubricant from 15 to 30% by mass;
- water-dispersible synthetic resin from 5 to 15% by mass;
- inorganic acid amine salt from 0.5 to 3% by mass;
- and water from 47 to 77% by mass, for 100% by mass of the total mass of the lubricant composition,
- wherein said water-dispersible synthetic resin is a vinyl acetate polymer obtained by emulsion polymerization using protective colloid selected from a group consisting of hydroxyethyl cellulose, sodium salt of carboxymethyl cellulose, and ammonium salt of carboxymethyl cellulose, or a vinyl acetate polymer obtained by emulsion polymerization using co-polymeric surfactant, and
- the inorganic acid of said inorganic acid amine salt is selected from boric acid, molybdenum acid or tungsten acid.
