Abstract
Description
본 발명은 신규한 세라믹 소재와 그 제조방법에 관한 것이다.The present invention relates to a novel ceramic material and a manufacturing method thereof.
세라믹이란 일반적으로 금속과 비금속 또는 준금속들이 열처리에 의해 서로 결합하여 결정질을 만드는 소결과정을 거쳐, 형성된 결정질들이 모여 3차원적 망구조를 형성한 고체 물질을 의미한다. 과거에는 주로 천연 원료인 점토로부터 제조한 요업 가공 물질을 의미했으나, 현대에 들어서는 폭넓은 의미로 결정질을 가지는 무기물질을 형성하는 요업 제조 과정과 요업 제품까지 포함하는 것으로 통용되고 있다.Ceramic generally refers to a solid material in which metals and non-metals or metalloids are bonded to each other by heat treatment to form crystals through a sintering process, where formed crystals are gathered to form a three-dimensional network structure. In the past, it mainly meant ceramic processed materials manufactured from clay, a natural raw material, but in modern times, it is commonly used to include ceramic manufacturing processes and ceramic products that form inorganic materials having crystals in a broad sense.
세라믹 물질은 비교적 단단하고, 산이나 염기 등의 부식성 조건에서도 높은 저항성을 나타내어, 예로부터 타일, 도기, 고온 단열재, 전자재료 등 다양한 분야에서 활용되고 있다. Ceramic materials are relatively hard and exhibit high resistance even under corrosive conditions such as acid or base, and have been used in various fields such as tiles, pottery, high-temperature insulation materials, and electronic materials.
특히, 최근에는 세라믹 소재의 흡수·흡습·탈취·항균 성능이 주목받으면서, 주방 및 욕실 용품의 개발에 적극적으로 활용되고 있다. 한편, 시중의 세라믹 소재를 활용한 주방 및 욕실 용품은, 물의 사용이 많은 주방 및 욕실 환경에 노출되면서, 소재에 함유된 성분들이 쉽게 용출되거나, 외부 힘에 의해 쉽게 부러지는 한계에 직면한 상황이다.In particular, recently, as the absorption, moisture absorption, deodorization, and antibacterial performance of ceramic materials have been attracting attention, they are actively used in the development of kitchen and bathroom products. On the other hand, kitchen and bathroom products using ceramic materials on the market face limitations in that components contained in the material are easily eluted or easily broken by external forces, as they are exposed to kitchen and bathroom environments with a lot of water use. .
일 측면에서, 본 발명의 목적은 치밀한 구조를 갖는 세라믹 소재를 제공하는 것이다.In one aspect, an object of the present invention is to provide a ceramic material having a dense structure.
일 측면에서, 본 발명의 목적은 물리적 안정성 및 화학적 안정성이 우수한 세라믹 소재를 제공하는 것이다. In one aspect, an object of the present invention is to provide a ceramic material having excellent physical and chemical stability.
일 측면에서, 본 발명의 목적은 흡습, 탈취 및 항미생물 효과가 우수한 세라믹 소재를 제공하는 것이다.In one aspect, an object of the present invention is to provide a ceramic material having excellent moisture absorption, deodorization and antimicrobial effects.
일 측면에서, 본 발명의 목적은 인체 안전성이 담보된 세라믹 소재를 제공하는 것이다.In one aspect, an object of the present invention is to provide a ceramic material that ensures human safety.
상기 목적을 달성하기 위하여, 본 발명은 일 측면에서, 규토조, 알루미나, 맥반석, 제올라이트, 패각 분말 및 금속 촉매를 포함하는, 다공성 세라믹 소재를 제공한다.In order to achieve the above object, in one aspect, the present invention provides a porous ceramic material including silica, alumina, elvan, zeolite, shell powder and a metal catalyst.
