Abstract

PURPOSE: To prepare magnetic paint containing magnetic metal powder such as iron powder, nickel powder, etc. in high dispersion, by dispersing the magnetic metal powder in a part of a polyurethane binder, and compounding the dispersion thus obtained with the remaining part of the binder.
CONSTITUTION: In the compounding and dispersion of powder of metal such as iron, nickel, cobalt, etc. with a binder to obtain a magnetic paint, the metal powder is first dispersed in a part of a polyurethane resin used as a component of the binder, and then the remaining part of the binder is mixed and dispersed with the dispersion obtained above.
EFFECT: Uniform dispersion can be attained in an extremely short time, and the viscosity of the prepared paint can be made lower than that of the paint prepared by the simultaneous compounding of the whole binder components.
