PURPOSE: A preparation method of an interior paint composition for a cathode ray tube, an interior paint composition prepared by the method and a cathode ray tube coated with the composition are provided, to stabilize the electrical resistance of the interior paint for a cathode ray tube by controlling the dispersibility and the electrical properties. CONSTITUTION: The method comprises the steps of dispersing 10-90 wt% of titanium alkoxide solution or iron acetate solution whose solid content is 1-30 % in 10-90 wt% of an organic solvent; dipping 3-20 wt% of graphite particle into the dispersion solution and heating it at 60-150 deg.C for 1 hour to dope the graphite particle with titanium dioxide or iron oxide; and dispersing 3-20 wt% of the doped graphite particle and 30-50 wt% of water glass as a binder in 10-30 wt% of water. Preferably the organic solvent is selected from the group consisting of toluene, methylisobutylketone, methylethylketone, ethyl acetate and xylene; and the graphite particle has a particle size of 0.1-2 micrometers. |
