Document Type and Number:
Japanese Patent JP5270133
Kind Code:
B2
Abstract:

To provide a hydroforming lubricant, which exhibits excellent lubrication and seizure preventing performance to prevent break, buckling, damage on the surface during a hydroforming process and can be removed after the molding process; a hydroforming metallic tube using the lubricant, and a hydroforming processing method.

The hydroforming lubricant comprises 0.1-10 wt.% of wax with a melting point 45-110°C on a solid weight basis, and the rest of the hydroforming lubricant consists of at least one of a soluble aqueous resin and a surfactant. Preferably, the wax consists of one or more kinds of wax among carnauba wax, lanolin, and paraffin, while the soluble aqueous resin consists of one or more kinds of resin among acrylic resin with molecular weight of 5,000-100,000, polyalkylene glycol with molecular weight of 800-35,000, urethane resin, polylactic acid, and polyvinyl alcohol.
