Method for preparing MgO based nano-sized powders for protective layer of PDP application

摘要

The present invention relates to a method for producing MgO-based nanopowder for PDP (Plasma Display Panel) protective film, comprising the steps of: (a) impregnating an aqueous metal salt solution of magnesium (Mg) into a polymer material; And (b) putting the polymer material impregnated with the aqueous metal salt solution in step (a) into a furnace at room temperature and heating to 800 to 1400 ° C. for calcination. It is about a method. As a result, MgO-based nanopowders having a uniform particle size at low temperature can be obtained, and the nanoparticles can be prepared by pelleting to increase the density, thereby preventing the adhesion of impurity gas to the surface of the PDP protective film. The power consumption can be reduced by increasing the brightness of the discharge cells.;PDP, MgO-based, nano powder, metal salt aqueous solution
