Abstract
PURPOSE:The titled white releasing agent with good releasability, preventing a metal mold from seizing by application to the mold, which is prepared by mixing a powdered mica having structural formula contg. an OH gp. with a specified wax. CONSTITUTION:A powdered mica of structural formula including an OH gp. [e.g., KMg3 (AlSi2O10)(OH)2] is mixed with a wax of initial boiling pt. <=230 deg.C (e.g., a microcrystalline wax) in a 1.5<=wax to mica <=9 ratio, and the resulting mixt. is emulsified in water. In the plastic processing of a metal material under high temperatures such as hot forging, when a material heated to about 1,000 deg.C is inserted into a metal mold, to which the releasing agent has been applied and pressed, the wax in the releasing agent is vaporized. Space between mica flakes is filled with the vapor evolved and water vapor evolved from the mica, which, preventing the mica flakes from contacting mutually, forms a films rich in plasticity. The film prevents seizing by inhibiting the material to be worked from being brought into contact with the metal mold.
