CERAMIC SLURRY COMPOSITION FOR 3D PRINTING, AND METHOD FOR PRODUCING HIGH-STRENGTH CERAMIC STRUCTURE USING SAME
The present invention relates to a ceramic slurry composition for 3D printing, and a method for producing a high-strength ceramic structure using same, and more specifically, provides a ceramic slurry composition for 3D printing, and a method for producing a high-strength ceramic structure using same, the ceramic slurry composition comprising: 60-80 parts by weight of ceramic particles coated with an inorganic binder precursor solution comprising sodium (Na); 15-35 parts by weight of a photocurable resin; and 0.1-5 parts by weight of a dispersant, wherein the photocurable resin comprises 80-90 parts by weight of a photopolymerizable monomer, 1-10 parts by weight of a photoinitiator, and other additives, and the composition is photopolymerized by being irradiated with light, and then aged at 50-200°C for 1-3 hours, thereby having enhanced strength. By using ceramic particles modified with an inorganic binder instead of the conventional sintering process, high strength may be gained, and deformation which may occur in a heat treatment process may be minimized.
La présente invention concerne une composition de suspension céramique pour impression 3D, et un procédé de production d'une structure céramique à haute résistance l'utilisant, et plus particulièrement, concerne une composition de suspension céramique pour impression 3D, et un procédé de production d'une structure céramique à haute résistance l'utilisant, la composition de suspension céramique comprenant : 60 à 80 parties en poids de particules de céramique revêtues d'une solution de précurseur de liant inorganique comprenant du sodium (Na) ; 15 à 35 parties en poids d'une résine photodurcissable ; et 0,1 à 5 parties en poids d'un dispersant, la résine photodurcissable comprenant 80 à 90 parties en poids d'un monomère photopolymérisable, 1 à 10 parties en poids d'un photo-initiateur, et d'autres additifs, et la composition étant photopolymérisée en étant exposée à de la lumière, puis vieillie à 50 jusqu'à 200 °C pendant 1 à 3 heures, ce qui permet d'obtenir une résistance améliorée. En utilisant des particules de céramique modifiées avec un liant inorganique au lieu du procédé de frittage classique, une résistance élevée peut être obtenue, et une déformation qui peut se produire dans un processus de traitement thermique peut être réduite au minimum.
본 발명은 3D 프린팅용 세라믹 슬러리 조성물 및 이를 이용한 고강도 세라믹 구조체의 제조방법에 관한 것으로, 보다 상세하게는 나트륨(Na)을 포함하는 무기 바인더 전구체 용액으로 코팅된 세라믹 입자 60 내지 80 중량부; 광경화성 수지 15 내지 35 중량부; 및 분산제 0.1 내지 5 중량부를 포함하는 세라믹 슬러리 조성물로, 상기 광경화성 수지는 광중합성 단량체 80 내지 90 중량부, 광개시제 1 내지 10 중량부, 및 기타 첨가제로 이루어지며, 상기 조성물에 광을 조사하여 광중합 후, 50 내지 200℃에서 1 내지 3 시간 에이징(aging)하여 강도를 향상시킨 것을 특징으로 하는, 3D 프린팅용 세라믹 슬러리 조성물 및 이를 이용한 고강도 세라믹 구조체의 제조방법을 제공한다. 종래의 소결 공정 대신 무기 바인더로 개질된 세라믹 입자를 이용하여 높은 강도를 가지고 열처리 과정에서 발생할 수 있는 변형을 최소화할 수 있다.
