본 발명은 플라즈마디스플레이패널(PDP)용 백색유전체 프리트 조성에 관한 것으로서 25-50중량퍼센트의 산화비스무스(Bi2O3), 10-20중량퍼센트의 산화바륨(BaO), 10-20중량퍼센트의 산화아연(ZnO), 10-20중량퍼센트의 산화붕소(B2O3)의 조성을 갖는 유리프리트에 고 굴절율을 갖는 결정질필러로 아나타제(Anatase)형과 루타일(Rutile)형의 산화티타튬(TiO2), 산화바륨(BaO), 산화바륨(BaO)+산화티타늄(TiO2(anatase)), 산화바륨(BaO)+산화티타늄(TiO2(rutile))을 일정비율로 첨가 혼합하여 소다라임기판유리(soda-lime silicate substrate glass)위에 도포한 후 480-540℃에서 소성 했을 때, 백색유전체로 제조되는 것으로, 종래의 백색유전체가 갖는 특성을 유지 또는 증가시키고 친환경적인 저온 소성 가능한 무연의 백색 유전체를 제조하는 것에 관한 것이다. The present invention relates to a white dielectric frit composition for plasma display panel (PDP), 25-50% by weight of bismuth oxide (Bi 2 O 3 ), 10-20% by weight of barium oxide (BaO), 10-20% by weight of It is a crystalline filler having a high refractive index in a glass frit having a composition of zinc oxide (ZnO) and 10-20% by weight of boron oxide (B 2 O 3 ) and anatase type and rutile type titanium oxide ( TiO 2 ), Barium Oxide (BaO), Barium Oxide (BaO) + Titanium Oxide (TiO 2 (anatase)), Barium Oxide (BaO) + Titanium Oxide (TiO 2 (rutile)) by adding and mixing in a certain ratio When coated on a soda-lime silicate substrate glass and calcined at 480-540 ° C, it is made of white dielectric, and maintains or increases the characteristics of conventional white dielectrics and is environmentally friendly at low temperature. Relates to manufacturing a dielectric.

기존의 백색 유전체의 프리트 조성으로는 중량으로 24.6중량퍼센트 산화실리 카(SiO2), 65.3중량퍼센트 산화납(PbO), 5.8중량퍼센트 산화붕소(B2O3), 4.3중량퍼센트 산화알루미늄(Al2O3)를 갖는다. 이 프리트 조성물에 고 굴절율을 갖는 TiO2결정질 필러를 15중량% 첨가 혼합하여 백색유전체를 제조하였다. The frit compositions of conventional white dielectrics are 24.6 weight percent silicon oxide (SiO 2 ), 65.3 weight percent lead oxide (PbO), 5.8 weight percent boron oxide (B 2 O 3 ), and 4.3 weight percent aluminum oxide (Al). 2 O 3 ). A white dielectric material was prepared by adding 15 wt% of TiO 2 crystalline filler having a high refractive index to the frit composition.

이 백색유전체는 어드레스(Address)전극이 형성된 소다라임규산(Soda-lime silicate)유리기판 위에 스크린 프린팅법으로 형성된다. 이때, 백색유전체는 가시광 반사에 의한 발광효율 향상, 확산 방지등의 역할을 하게 되는 것이다. 따라서, 백색유전체가 갖춰야 할 특성으로는 높은 가시광선 반사율, 기판유리와 유사한 열팽창계수, 낮은 소성온도, 낮은 유전상수를 가져야 한다.The white dielectric is formed by screen printing on a soda-lime silicate glass substrate having an address electrode formed thereon. At this time, the white dielectric is to play a role of improving the luminous efficiency, preventing diffusion by visible light reflection. Therefore, the white dielectric should have high visible light reflectance, thermal expansion coefficient similar to that of substrate glass, low firing temperature, and low dielectric constant.

현재 위 특성을 만족시키며 사용되는 기존의 백색유전체는 인체에 해로운 산화납(PbO)성분이 최소 60중량%이상 다량 함유되어 있기 때문에 플라즈마 디스플레이 패널(PDP) 폐기 시 폐수 중의 산 또는 알칼리 용액과 화학반응을 일으키게 되면 토양 및 수질오염을 비롯한 환경공해를 유발시키고 인체에도 유해한 영향을 주는 문제점이 있다.  The existing white dielectric used to satisfy the above characteristics currently contains a large amount of lead oxide (PbO) that is harmful to the human body at least 60% by weight, so when the plasma display panel (PDP) disposal, chemical reaction with acid or alkaline solution in the wastewater If it causes a problem that causes environmental pollution, including soil and water pollution and harmful effects on the human body.

본 발명은 상기와 같은 문제점을 해소하기 위해 납성분을 함유하지 않는 산화비스무스-산화아연-산화바륨-산화붕소계 프리트 조성에 고 굴절율을 갖는 결정질 필러를 첨가하여 높은 가시광 반사에 의한 반사율 향상과 유리기판과의 열팽창계수 를 정합시켜 유리기판과의 사이에서 견고한 밀착성을 갖는 후막을 제조하는데 있다.In order to solve the above problems, the present invention adds a crystalline filler having a high refractive index to a bismuth oxide-zinc oxide-barium oxide-boron oxide-based frit-free composition, which does not contain lead, thereby improving the reflectance and glass by high visible light reflection. By matching the coefficient of thermal expansion with the substrate to produce a thick film having a strong adhesion between the glass substrate.

상기와 같은 유리기판과의 사이에 견고한 밀착성을 갖는 후막을 제조하는 기술수단으로는As a technical means for producing a thick film having a strong adhesion between the glass substrate as described above

산화비스무스(Bi2O3), 산화바륨(BaO), 산화아연(ZnO), 산화붕소(B2O3)의 조성을 갖는 유리프리트에 고굴절율을 갖는 결정 필러를 혼합하여 소다라임 기판유리 위에 도포한 후 480-540℃에서 소성하는 것을 과제해결 수단으로 한다.A glass frit having a composition of bismuth oxide (Bi 2 O 3 ), barium oxide (BaO), zinc oxide (ZnO), and boron oxide (B 2 O 3 ) is mixed with a crystal filler having a high refractive index and coated on a soda-lime substrate glass. After that, firing at 480-540 ° C is a problem solving means.
