Abstract
PURPOSE: A magnetic water paint with excellent magnetic and power output characteristics, and good dispersibility, which is prepared by the incorporation of a water- soluble salt of an isobutylene-maleic anhydride copolymer as a dispersing agent.
CONSTITUTION: A water-soluble salt (e.g., a sodium or ammonium salt) of an isobutylene-maleic anhydride copolymer is used as a dispersing agent. For example, 100pts.wt. mgnetic powder (e.g., γ-iron oxide needle), about 0.5pts.wt. dispersant (e.g., sodium pyrophosphate), about 4pts.wt. said dispersing agent and about 120pts.wt. water are mixed, and about 30 parts adhesive (e.g., a styrene-butadiene emulsion) is added to the resultig mixture. After dispersing treatment for about 2W3hr with a ball mill, to prepare a magnetic paint.
