Abstract

안료부착강도가 강한 고품질의 안료부착 형광체를 제공하기 위한 것으로서, 콜로이드성 실리카와 18∼20중량% 폴리비닐알코올 수용액을 1:1비율로 혼합한 분산액을 결합제로서 사용하여 형광체에 안료를 부착시킴을 특징으로 하는 안료부착 형광체의 제조방법은 안료부착강도와 발광휘도가 우수한 안료 부착형광체를 제공하며 또한 경화공정을 실시하지 않아도 되는 잇점이 있다.It is to provide high quality pigmented phosphors with strong pigment adhesion strength.The pigments are attached to the phosphors by using a dispersion mixture of colloidal silica and 18 to 20 wt% polyvinyl alcohol aqueous solution in a 1: 1 ratio as a binder. The method for producing a pigment-containing phosphor characterized in that it provides an excellent pigment-adhesive phosphor with excellent pigment adhesion strength and luminous luminance and does not require a curing process.
