Abstract
PURPOSE: To enhance dispersibility of a magnetic paint by performing admixing and dispersion of each component in two specified steps, in the preparation of the magnetic paint by use of a polyurethane resin and a vinyl chloride-vinyl acetate copolymer as binders.
CONSTITUTION: In the preparation of a magnetic paint consisting of a magnetic powders, binder, lubricant, abrasive material and additive by use of said two polymers as the binder, an iron metal powder (a magnetic powder) and a polyurethane resin are primarily dispersed and then secondarily dispersed with addition of the lubricant and a vinyl chloride-vinyl acetate copolymer. About 0.01W 10pts.wt., based on 100pts.wt. said magnetic powder, 14W20C saturated fatty acid (e.g. myristic acid) is used as lubricant.
