Description
본 발명은 패각을 이용한 건축 내장재의 제조방법 및 그에 의해 제조된 건축 내장재에 관한 것이다.The present invention relates to a method for manufacturing a building interior material using a shell and to a building interior material manufactured by the method.
일반적으로 건축용 내장재로 많이 사용하고 있는 타일은 장석, 석회석, 카올린, 지르콘, 아연화 등의 원료를 혼합하여 건식 및 습식분쇄 후 미소성된 타일의 소지 표면에 도포하여 건조한 다음, 약 1,000 ℃ 내지 1,200 ℃ 정도의 온도를 가진 로러허스 가마에서 소성하여 제조되게 된다.Tiles, which are generally used as interior materials for construction, are mixed with raw materials such as feldspar, limestone, kaolin, zircon, and zinc oxide, dry and wet crushed, applied to the surface of the unfired tile substrate, dried, and then dried at about 1,000 ℃ to 1,200 ℃ It is produced by firing in a low-heat kiln with a certain temperature.
이와 같이 종래기술에 따른 타일은 높은 온도에서 소성 가공함으로써 작업공정이 복잡하고, 제조과정시 고열처리 과정에 따른 2차환경오염과 비용 상승되는 문제가 있다.As described above, the tile according to the prior art has a complicated work process by plastic processing at a high temperature, and there is a problem of secondary environmental pollution and cost increase due to a high heat treatment process during the manufacturing process.
한편, 산업폐기물인 현재 발생되는 패각(貝殼)은 조개류의 껍데기로서, 현재 우리나라에서 발생하고 있는 패각은 분말로서 호분이나 제산제, 태운 조개재로서 도료, 매염제, 비료 등으로 이용되고, 단추의 제작, 비료 및 건자재 등과 같은 일차적 가공물로서의 활용, 칼슘성분을 추출하여 식품 또는 의약품으로서의 활용 등으로 실생활에 이용되고 있다.On the other hand, the currently generated shells, which are industrial wastes, are shells of shellfish, and the shells currently occurring in Korea are powdered aloe or antacid, and burned shellfish as paints, mordants, fertilizers, etc. It is used in real life for use as primary processing products such as fertilizers and construction materials, and for use as food or medicines by extracting calcium components.
그러나, 이러한 소비에도 불구하고 패각은 연간 30만 톤 이상이 폐기물로 처리되고 있어서 매립이나 야적을 위해 많은 유지 관리비를 발생시키며, 패각의 처리방식이 다양하게 보급되어 있지 않으므로, 대부분의 굴 패각은 해당 해역에 그냥 방치됨으로 인하여 부패된 악취를 발생시킬 뿐 아니라, 특히 해양폐기물의 주요 오염원으로 패각의 비율이 약 70 %에 달해 심각한 환경문제를 초래하고 있다.However, despite this consumption, more than 300,000 tons of shells are treated as waste annually, which incurs a lot of maintenance cost for landfilling or storage. Not only does it generate a rotten odor due to being left alone in the sea area, but in particular, the proportion of shells as a major source of pollution in marine wastes reaches about 70%, causing serious environmental problems.
따라서, 건축용이나 산업용에서 사용될 수 있도록 패각의 재활용은 이러한 문제점의 해결 방안으로서 요구되는 상황이다.Therefore, the recycling of shells so that they can be used for construction or industry is required as a solution to these problems.

종래의 패각을 재활용하는 방식은 1000 ℃이상의 고열소성으로 패각을 열처리하여 시멘트 몰탈과 섞어 건축자재로 사용한다. 그러나, 본 발명의 일 실시예에 따른 패각을 이용한 건축 내장재의 제조방법에서는 패각의 불순물과 연분을 제거할 때 고열을 사용하지 않으며, 인테리어 타일로 제조했을 경우에도 기존 도자기 타일에서 처리하는 방식인 유약을 바르고 고온에서 소성하는 방법을 사용하지 않기 때문에 제조과정이 친환경적 (이산화탄소 배출 저하, 전기 자원 사용절감)이고, 2차 환경오염의 피해가 없으며, 비용 절감의 이점이 있다.The conventional method of recycling shells is to heat-treat the shells by sintering at a high temperature of 1000 ℃ or more, and mix them with cement mortar and use them as building materials. However, in the method for manufacturing a building interior material using a shell according to an embodiment of the present invention, high heat is not used to remove impurities and smoke from the shell. Because it does not use the method of applying a coating and firing at a high temperature, the manufacturing process is eco-friendly (reduced carbon dioxide emission, reduced use of electric resources), there is no damage from secondary environmental pollution, and there are advantages of cost reduction.

Oyster shells and mussel shells are discarded in large quantities in Korea, so they are easy to obtain, and the high calcium carbonate ratio makes the strength stronger in molding, so use small particles mixed and adjust the ratio of other shells such as oysters, mussels, scallops, and abalone. Various aesthetic effects can be maximized.
