본 발명은 항균도자기 제품 및 그 제조방법에 관한 것으로서, 특히 내항균성 및 내기능성이 소멸되지 않고 장기간 유지되게 하므로서 음식물이 쉽게 부패되는 현상을 방지함과 동시에 장기 보존이 가능케한 것이다.The present invention relates to an antimicrobial ceramic product and a method of manufacturing the same, and in particular, it is possible to prevent long-term preservation while preventing the food from easily rot by maintaining antibacterial and functional resistance without disappearing.

일반적으로 도자기제품에 항균력이 부여되게 한 제품들이 간혹 제공되고 있으나 그 효과가 미미하여 일반도자기 제품들과 성능면에서 큰 차이를 나타내지 못하고 있는 실정이기 때문에 널리 애용되고 있지 않다.In general, products that have been given antimicrobial power to ceramic products are sometimes provided, but the effect is insignificant and is not widely used because it does not show a big difference in performance with general ceramic products.

본 발명은 이러한 종래의 제반단점을 시정하고자 내항균력이 우수한 양질의 도자기를 제조한 다음 사용케하므로서, 음식물이 쉽게 부패되는 것을 방지함과 동시에 장기 보관이 가능케 한 것이다.The present invention is to make a good pottery with excellent anti-bacterial force to correct the above-mentioned general disadvantages, thereby preventing the food from easily rot and at the same time to enable long-term storage.

실험한 바에 의하면 황색 포도상구균은 99%, 대장균 및 녹농균은 97%이상의 내항균력을 갖고 있는 것으로 측정되었으며, 상기 내항균기능은 1500℃이상에서도 안전성을 유지하는 것으로서 내항균기능이 소멸되지 않고 유지될 수 있게 한다.According to the experiment, Staphylococcus aureus was measured as having more than 99% of E. coli and Pseudomonas aeruginosa, and the antibacterial function is maintained at 1500 ℃ or higher, and the antibacterial function is maintained without disappearing. To be able.

상기 목적을 달성하기 위하여 본 발명은 천연연료인 장석과 규석, 고령토, 게르마늄, 점토, 도석 등을 혼합 습식분쇄한 후 탈수하여 일정한 수분만 유지되게 하고, 동시에 탈철(기계적으로 철분을 제거하는 작업)한 후 흙속의 공기를 제거시킨 다음 숙성 후 제품을 성형한다.In order to achieve the above object, the present invention is mixed with wet pulverized feldspar and silica, kaolin, germanium, clay, pottery, and the like, and then dehydrated to maintain only a constant moisture, and at the same time de-ironing (mechanical removal of iron) After removing the air in the soil, the product is molded after aging.

성형된 제품은 자연 건조후 정형(면을 고르게 하는 작업)을 하고 1차소성한다.The molded product is naturally dried, then shaped (worked to equalize the surface) and firstly fired.

1차소성된 제품표면에 유약을 도포하게 되며 이때 유약은 천연원료만 사용한다.The glaze is applied to the surface of the first fired product, using only natural raw materials.

상기 유약조성은 장석, 규석, 고령토, 석회석, 백운석 등이다.The glaze composition is feldspar, silica, kaolin, limestone, dolomite and the like.

1차소성된 제품표면에 1차유약도포가 완료되면 도포된 유약이 건조되게 하고, 그위에 다시 안티제로(Antizero)란 항균제를 도포하고, 2차소성하고, 2차소성 완료된 제품표면에 전사후 3차소성하므로서 본 발명에서 제공하고자하는 항균도자기제품의 제조가 완료된다.When the first glaze is applied to the surface of the first fired product, the applied glaze is dried, and then an antimicrobial agent called Antizero is applied on it, secondly fired, and transferred to the surface of the second fired finished product. By tertiary firing, the production of antimicrobial ceramic products to be provided in the present invention is completed.

이하 본발명 항균도자기의 제조방법을 상세히 설명하면 다음과 같다.Hereinafter, the method for preparing the antimicrobial ceramic of the present invention will be described in detail.

천연원료인 장석과 규석, 고령토, 게르마늄, 점토 및 도석을 혼합하여 약48시간 정도 습식분쇄한 후 탈수하여 일정한 수분만 유지되게 하고, 동시에 탈철(기게로 철분을 제거하는 작업)한 후 흙속에 함유된 공기를 완전히 제거시키고, 약24시간 숙성후 제품을 성형한다.Natural materials, feldspar, silica, kaolin, germanium, clay, and pottery are mixed and wet pulverized for about 48 hours, then dehydrated to maintain only a certain moisture, and at the same time de-ironed (work to remove iron with flag) and contained in the soil After the air is completely removed, the product is molded after aging for about 24 hours.

상기 원료준비공정에서 혼입되는 천연원료의 량은 전체 원료의 량을 100%일경우 장석 약18%, 규석 약20%, 고령토 약25%, 게르마늄 약10%, 점토 약20%, 도석 약7%정도로서 일반도자기제품의 원료조성비와 다를바 없으며, 제품성형수단에 있어서도 자동성형, 주입성형 및 가압성형 등 작업여건에 맞게 선택 사용하면 된다.The amount of natural raw materials mixed in the raw material preparation process is about 18% feldspar, about 20% silica, about 25% kaolin, about 10% germanium, about 20% clay and about 7% pottery when the total amount of raw materials is 100%. In terms of accuracy, it is no different from the raw material composition ratio of general ceramic products, and the product forming means may be selected and used according to the working conditions such as automatic molding, injection molding, and press molding.

상기에서와 같은 원료로 성형된 제품은 약24시간정도 자연건조시키고 자연건조 완료된 제품은 다시 표면을 고르게 가공하는 정형작업을 하고 1차소성에 들어간다.The products molded from the raw materials as described above are naturally dried for about 24 hours, and the products that are naturally dried are subjected to the shaping process to evenly process the surface again and enter the primary firing.

상기 1차소성은 약900℃에서 6시간정도 소성하고, 1차소성된 제품표면에 시유작업을 하게 되며 이때 사용되는 유약은 반드시 천연원료만 사용하여야 한다.The primary firing is calcined at about 900 ℃ for about 6 hours, and the first firing is applied to the surface of the fired product, and the glaze used must use only natural raw materials.

상기 유약의 조성은 장석, 규석, 고령토, 석회석, 백운석 등으로 된 것으로서 상기 조성의 유약을 제품표면에 1차 도포한 다음 건조한다.The glaze is composed of feldspar, silica, kaolin, limestone, dolomite, and the like, and the first glaze of the composition is dried on the surface of the product.

상기에서 설명한 공정은 일반적으로 도자기제조공정에서 널리 사용되고 있는 공정이다.The process described above is a process that is widely used in the ceramics manufacturing process in general.

본 발명에서 일반도자기 제조공정과 구별되는 것은 제품표면에 1차유약을 도포 건조한 다음 그 표면에 2차 항균제를 도포하여 2차소성하는 공정이다.What is distinguished from the general ceramic manufacturing process in the present invention is a process of secondary firing by applying a primary glaze on the surface of the product and then applying a secondary antimicrobial agent on the surface thereof.

상기에 도포되는 항균제는 안티제로(Antizero)란 항균제를 사용하게 되며, 2차소성조건은 1250∼1300℃에서 약10시간 정도 소성한다.The antimicrobial agent applied to the above is to use an antimicrobial agent (Antizero), the secondary firing conditions are baked for about 10 hours at 1250 ~ 1300 ℃.

2차소성완료된 제품은 선별한 후 표면에 전사작업 하고 800∼900℃에서 약 5시간 정도 3차소성하므로서 본 발명에서 제공하고자 항균도자기의 제조가 완료된다.After the secondary firing finished product is screened and transferred to the surface and the third firing for about 5 hours at 800 ~ 900 ℃ to complete the manufacture of antimicrobial ceramics to provide in the present invention.

상기에서와 같이 본 발명은 천연원료를 이용하여 성형, 건조, 정형 1차소성하고, 상기 1차소성하고, 상기 1차소성된 제품표면에 천연원료로된 유약을 도포건조후 본 발명공정의 특징인 항균제, 즉 안티제로(Antizero)를 도포하고, 2차소성, 전사, 3차소성하여 항균성을 갖는 도자기제품을 얻을 수 있게 되고, 상기 방법으로 제조된 항균도자기제품은 항균성 검사결과 황색 포도상구균은 약99%, 대장균 및 녹농균은 약97%이상의 내항균력을 유지하고 있음이 입증되었다.As described above, the present invention is characterized by the process of the present invention after drying, molding, drying, shaping primary firing using a natural raw material, applying the primary firing, and applying the glaze of natural raw material to the primary fired product surface. Phosphorus antimicrobial, that is, anti-zero (Antizero) is applied, secondary firing, transfer, tertiary firing to obtain a ceramic product having antimicrobial properties, the antimicrobial ceramic products produced by the above method is antibacterial test results yellow staphylococcus About 99%, Escherichia coli and Pseudomonas aeruginosa have proven to have an antibacterial activity of about 97% or more.

따라서 상기 도자기제품으로 음식물을 조리보관할 경우 쉽게 부패되는 현상을 방지할 수 있게 될뿐 아니라 장기보존이 가능하다.Therefore, when the food is stored in the porcelain product, it is possible to prevent the phenomenon of corruption easily as well as long-term preservation.

또한 무기질제 항균제인 안티제로는 약1500℃이상에서도 안전성을 유지하게 되므로 제조과정이나 사용중 항균력이 소실되는 경우가 없게 된다.In addition, the antimicrobial agent, which is an inorganic antimicrobial agent, maintains safety at about 1500 ° C. or higher so that the antimicrobial activity is not lost during the manufacturing process or during use.

뿐만 아니라 LD50경구 투여, 피부자극시험, 돌연변이시험 등의 여러가지로 측정한 결과 인체에 무해하며 안정성이 탁월하여 제품화에 아무런 문제가 없음이 입증되었다.In addition, as a result of various measurements such as LD50 oral administration, skin irritation test, and mutation test, it was proved to be harmless to the human body and excellent in stability, thus having no problem in commercialization.

이상과 같이 본 발명은 도자기제품을 제조하는 과정에서 1차소성된 제품의 표면에 1차유약을 도포 건조한 다음 그 표면에 다시 항균제인 안티제로(Antizero)를 도포하여 2차소성, 전사, 3차소성하여 항균도자기 제품을 제조사용케 하므로서 음식물 조리시 음식물이 쉽게 부패되는 현상을 방지함과 동시에 장기보존이 가능케 하므로 음식물의 위생적 보관, 관리가 가능한 고품질의 향균도자기를 제공받을 수 있게 되는 등의 효과가 있는 것이다.As described above, the present invention applies the first glaze to the surface of the first fired product in the process of manufacturing ceramic products, and then applies the anti-zero agent (Antizero) to the surface again to apply the second firing, transfer, third By firing and manufacturing antimicrobial ceramic products, it prevents the food from easily decaying during cooking, and enables long-term preservation. Therefore, it is possible to provide high-quality antibacterial ceramics that can be hygienicly stored and managed. It is.
