Description

안료부착 형광체의 제조방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 종래의 안료부착전의 제품과 본 발명에 의해 제조된 안료부착후의 제품과의 입경 분포를 비교한 그래프이다.

Claims (3)

  1. 형광체 입자에 아크릴 에멀젼을 부착한 분산 수용액과 안료입자에 폴리비릴 알코올을 부착한 분산 수용액을 제조하고, 상기에서 제조된 두 분산 수용액을 균일하게 혼합한 후 그 혼합물에 산성액을 첨가하여 pH 7 내지 3으로 조절한뒤, 상기 혼합물에 경화제로서 옥살산을 적량 첨가하여 안료입자를 형광체 입자 표면에 부착하도록 하는 것을 특징으로 하는 안료부착 형광체의 제조방법.
  2. 제1항에 있어서, 상기 경화제로서 사용되는 옥살산의 양이 형광체 100중량부에 대해 0.001 내지 0.5중량부의 범위에 있는 것을 특징으로하는 안료부착형광체의 제조방법.
  3. 제1항에 있어서, 상기 아크릴 에멀젼과 폴리 비닐 알코올의 양이 각각 형광체 100중량부에 대해 0.005 내지 1중량부와 0.001 내지 0.1 중량부의 범위에 있는 것을 특징으로 하는 안료부착 형광체의 제조방법.
