Description

카본 도자 조형물{ceramics with cabon layer}Carbon ceramics sculpture {ceramics with cabon layer}

본 발명은 카본 도자 조형물에 관한 것으로, 더욱 상세하게는 목분과 목질이 탄화된 탄소체 분말을 함께 포함하면서 도자기유약을 혼합한 상태의 조성물을 성형함으로 산화염만으로 소성시켜도 탄화된 탄소층을 형성할 수 있게 되어 경제적이면서 간편하게 이중구조로 제작할 수 있게 된 카본 도자 조형물에 관한 것이다. The present invention relates to a carbon ceramic sculpture, and more particularly, to form a carbonized carbon layer by firing only the oxidized salt by molding a composition containing a mixture of ceramic glaze and wood powder and carbonized carbon body powder together The present invention relates to a carbon ceramic sculpture that can be economically and conveniently manufactured in a dual structure.

종래의 대표적인 점토블록은 점토와 규사를 혼합하여 건조시킨 다음 1100~1200℃의 온도에서 소성하여 제조된다. 이러한 점토블록은 점토와 규사의 혼합물의 무게가 비교적 무거워서 완성된 점토블록 역시 무게가 무겁다는 단점이 있다.Representative conventional clay blocks are manufactured by mixing clay and silica sand and drying and firing at a temperature of 1100 ~ 1200 ℃. The clay block has a disadvantage that the finished clay block is also heavy because the weight of the mixture of clay and silica sand is relatively heavy.

이에, 점토 블록의 무게를 경감시키고자 점토 및 규사 혼합물에 톱밥이나 왕겨와 같은 목분를 추가로 포함시키는 블록이 제안되었다. 그러나 이러한 블록은 소성과정에서 소성화염에 의하여 목분이 탄소체로 부분 부분 남아있거나 완전히 연소되어 다공질 블록을 형성하게 됨으로써 외관을 손상시키는 문제점이 있다.In order to reduce the weight of the clay block, a block for adding wood powder such as sawdust or chaff to clay and silica sand mixture has been proposed. However, these blocks have a problem in that the wood powder is partially burned by carbon fire during firing or completely burned to form a porous block, thereby damaging the appearance.

이러한 목분 첨가의 문제를 개선하기 위하여 단계별로 구별되는 열원을 제공하여 소성을 진행하는 방법이 개발되어 제안되었다. 즉, 일단 환원염으로 소성시켜 목분을 연소한 후 전체적으로 탄소체로 형성시키고, 이후 산소를 공급하는 중성염 또는 산화염으로 일정시간 소성시켜 표면의 탄소체만를 완전히 기화시키고 내부의 탄소체는 그대로 남아있게 한 것이다. 그러나, 이와 같은 방법은 열원을 구분하여 제공하여야 하므로 작업이 복잡해지고, 또한 고가의 환원염(일정온도의 환원염은 산화염에 비해 많은 연료비와 가열시간이 요구됨)의 필수적인 이용에 따라 비경제적이게 된다. 나아가 산화염 제공시간이 길어지게 되면 내부에 있는 탄소체 또한 기화될 우려가 있기 때문에 산화염 제공에는 주의가 요구된다는 불편을 수반한다.In order to improve the problem of wood flour addition, a method of progressing firing by providing a heat source distinguished in stages has been developed and proposed. In other words, once the wood powder is burned with a reducing salt and burned to form a carbon body as a whole, it is then calcined with a neutral salt or an oxidizing salt supplying oxygen for a predetermined time to completely vaporize only the carbon body on the surface, and the carbon body inside remains as it is. . However, such a method is complicated because the heat source must be provided separately, and also becomes uneconomical due to the essential use of expensive reducing salt (reducing salt at a constant temperature requires more fuel cost and heating time than oxidizing salt). Furthermore, when the oxidizing salt providing time is prolonged, there is a risk that carbon dioxide inside may also be vaporized, and thus caution is required for oxidizing salt providing.

본 발명은 상기한 종래의 문제를 개선하고자 안출된 것으로서, 목분과 목질이 탄화된 탄소체 분말을 함께 포함하면서 도자기유약을 혼합한 상태의 조성물을 성형함으로 산화염만으로 소성시켜도 탄화된 탄소층을 형성할 수 있게 되어 경제적이면서 간편하게 제작할 수 있게 된 카본 도자 조형물을 제공하는데 그 목적이 있다.The present invention has been made to improve the above-described conventional problems, and by forming a composition of the ceramic powder mixed with wood powder and wood carbonized carbon powder to form a carbonized carbon layer even by firing with only an oxidized salt It is an object of the present invention to provide a carbon ceramic sculpture that can be economically and easily manufactured.

상기한 목적달성을 위해 본 발명은 황토 57~68중량%, 점토 9~20중량%, 맥반석분 2~5중량%, 샤모트 3~7중량%, 목분 3~8중량%, 목질이 탄화된 탄소체 분말 3~5중량%, 물 11~13중량%, 도자기유약 1~3중량%를 포함하여 혼합한 조성물을 성형하여 1150~1250℃의 가마에서 산화염으로 소성시킨 것을 특징으로 하는 카본 도자 조형물을 제공한다.The present invention for achieving the above object is 57 to 68% by weight of clay, 9 to 20% by weight of clay, 2 to 5% by weight of millstone, 3 to 7% by weight of chamotte, 3 to 8% by weight of wood powder, carbonized carbon A carbon ceramic sculpture comprising a composition comprising 3 to 5 wt% of sieve powder, 11 to 13 wt% of water, and 1 to 3 wt% of ceramic glaze was molded and calcined with an oxidized salt in a kiln at 1150 to 1250 ° C. to provide.

이하, 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.

본 발명에서는 도자 조형물을 제작하기 위한 원재료서 황토 57~68중량%, 점토 9~20중량%, 맥반석분 2~5중량%, 샤모트 3~7중량%, 목분 3~8중량%, 목질이 탄화된 탄소체 분말 3~5중량%, 물 11~13중량%, 도자기유약 1~3중량%를 포함하여 혼합한 조성물을 선택한다. 상기 조성물의 조성범위는 각 성분의 성질발현을 위해 최적화한 범위이다. In the present invention, raw materials for producing ceramic sculptures are 57 to 68% by weight of clay, 9 to 20% by weight of clay, 2 to 5% by weight of bedrock powder, 3 to 7% by weight of chamotte, 3 to 8% by weight of wood powder, and wood carbonized. 3 to 5% by weight of the carbonaceous powder, 11 to 13% by weight of water, and 1 to 3% by weight of ceramic glaze are selected. The composition range of the composition is the range optimized for the expression of the properties of each component.

본 발명에서는 특히 목분과 목질이 탄화된 탄소체 분말을 함께 포함하면서 도자기유약을 혼합한 상태의 조성물을 이용하여 성형물을 제작하고 있는데, 이는 산화염만으로 소성시켜 이중구조의 카본 도자 조형물을 완성할 수 있도록 하기 위함이다. 소성온도는 일반적인 도자기의 소성온도인 1150~1250℃로 한다.In the present invention, in particular, the powder is produced using a composition containing a mixture of porcelain glaze while carbon powder and carbon is carbonized powder, which is fired only by oxidizing salt to complete a carbon ceramic sculpture having a dual structure. To do this. The firing temperature is 1150 ~ 1250 ℃ which is the firing temperature of general ceramics.

황토와 점토는 도자 조형물을 제작하기 위한 주요 성분이 되는 것으로서, 본 발명에서는 황토를 다량 함유하도록 함으로 벽돌 등과 같은 건축 자재로 완성되는 경우 친환경적인 요소로 작용하도록 하고 있다.Ocher and clay are to be a major component for producing a ceramic sculpture, in the present invention is to contain a large amount of loess so that when it is completed with a building material such as bricks to act as an environmentally friendly element.

맥반석분은 미세구멍으로 이루어져 흡착성이 강하고, 무기염류의 함유로 중금속과 이온을 교환하는 작용을 하며 또한 원적외선을 방출하는 성질을 갖는다. 이러한 성질은 본 발명에서도 그대로 발현된다.Elvan powder is composed of fine pores, has strong adsorption property, and contains inorganic salts to exchange ions with heavy metals and emit far infrared rays. This property is expressed as it is in the present invention.

샤모트(Schamotte)는 내화 점토(耐火粘土)를 1300∼1400℃의 고온으로 가열한 후 부수어서 3mm 이하의 알갱이로 만든 것으로, 내화성을 향상시키면서 소성시의 수축율을 저하시키기 위해 첨가하는 재료이다. Chamotte is made of granules of 3 mm or less after heating fire clay at a high temperature of 1300 to 1400 ° C., and is added to reduce the shrinkage during firing while improving fire resistance.

샤모트의 첨가로 본 발명에 따른 카본 도자 조형물을 벽돌 등과 같은 건축용 자재로 만드는 경우 내화성 확보할 수 있게 해준다.The addition of the chamotte makes it possible to ensure fire resistance when the carbon ceramic sculpture according to the present invention is made of a building material such as brick.

목분은 톱밥의 형태로 사용되며, 소성시 탄소체로 되므로 이를 첨가한 도자 조형물은 내구성과 원적외선 방출효과를 발현하게 된다. 또한 소성시 탄화과정을 거치고 나아가 조형물의 표면에 있는 것은 연소되기도 하는 바, 도자 조형물의 경량화에 기여하는 역할을 하기도 한다. Wood flour is used in the form of sawdust, and since it becomes a carbon body during firing, ceramic sculptures added with it exhibit durability and far-infrared emission effects. In addition, what is on the surface of the sculpture is also burnt through the carbonization process during firing, and also contributes to the weight reduction of the ceramic sculpture.

본 발명에서는 목분 외에 목질이 탄화된 탄소체 분말을 직접 함유하도록 하는데, 이는 목분이 탄화되는데 걸리는 시간을 줄이면서 도자 조형물에 안정성 있는 탄소체를 공급하기 위함이다. 목질(木質)이 탄화된 탄소체 분말로는 숯, 갈탄, 흑연 등을 가장 대표적으로 들 수 있으며, 위 예시 중 갈탄분말이 가장 경제적이다.In the present invention, in addition to wood flour, the wood directly contains a carbonized carbon powder, which is intended to supply a stable carbon body to the ceramic sculpture while reducing the time taken for the carbon powder to be carbonized. Wood carbonized carbon powder is most representative examples of charcoal, lignite, graphite, etc., lignite powder is the most economic among the above examples.

물은 본 발명에서 11~13중량%를 함유하도록 하고 있는데, 이는 통상 도자 성형시보다는 작은 양으로서 샤모트의 첨가로 인한 수축율 저하효과를 감안한 것이다.Water is to contain 11 to 13% by weight in the present invention, which is in consideration of the shrinkage reduction effect due to the addition of chamotte in a smaller amount than in the case of the usual ceramic molding.

본 발명에서는 도자기유약을 성형물 표면에 바르는 것이 아니라 성형물을 제 작하기 위한 원재료 조성물에 포함시키고 있다. 이는 산화염만을 이용하여 소성하여도 이중구조를 갖는 도자 조형물을 완성하기 위함이다. In the present invention, the ceramic glaze is not applied to the molding surface, but is included in the raw material composition for producing the molding. This is to complete a ceramic sculpture having a dual structure even when fired using only an oxide salt.

도자기유약을 포함하지 아니한 상태의 원료로 성형물을 제작하고 이를 산화염으로 바로 소성시키면, 목분과 목질이 탄화된 탄소체 분말이 연소되면서 기화(탄소성분이 밖으로 분출되어 버림)되어 이 자리에 미세한 구멍이 형성되므로 다공성 도자 조형물로 완성될 것이다. 한편, 도자기유약을 포함하지 아니한 상태의 원료로 성형물을 제작하고 소정 전에 도자기유약을 발라 소성시키면, 도자기유약에 의해 피막이 형성되어 목분과 목질이 탄화된 탄소체 분말은 연소되지만 도자기유약 피막에 차단되면서 기화되지 못한 채 갇히게 되므로 전체적으로 탄소체가 형성된 도자 조형물로 완성될 것이다. When the molding is made from raw materials without ceramic glaze and fired directly with an oxidized salt, carbon powder of carbonized wood and wood is burned and vaporized (carbon component is ejected out) and fine pores are formed in this place. As it is formed, it will be completed with porous ceramic sculptures. On the other hand, if a molded article is made of a raw material that does not contain porcelain glaze and the ceramic glaze is fired before the predetermined time, the film is formed by the porcelain glaze, and the carbon powder powdered with wood powder and wood is burned, but is blocked by the porcelain glaze film. It will be trapped without vaporization, so it will be completed as a ceramic sculpture with carbon body as a whole.

그런데, 본 발명에서는 도자기유약을 포함한 상태의 원료로 성형물을 제작하므로, 산화염으로 바로 소성시키더라도 도자기유약이 피막을 형성하기 전에 성형물 표면에 있는 목분과 목질이 탄화된 탄소체 분말은 연소되면서 기화될 것이며, 내부에 있는 목분과 목질이 탄화된 탄소체 분말이 연소되는 동안 도자기유약이 성형물의 피막을 형성함으로 내부에 있는 목분과 목질이 탄화된 탄소체 분말은 연소되지만 더 이상 기화되지는 못하고 내부에 갇히게 될 것이다. 이로써 내부에 탄소층이 형성된 이중구조의 도자 조형물이 완성된다. However, in the present invention, since the molding is made of a raw material containing porcelain glaze, the wood powder and the carbonized carbonaceous powder on the surface of the molding may be vaporized while the porcelain glaze is burned even if it is directly fired with an oxidized salt. The ceramic glaze forms a coating film while the wood powder and wood carbonized carbon powder are burned, so that the wood powder and wood carbonized carbon powder is burned but not vaporized anymore. You will be trapped. This completes a dual-layered ceramic sculpture having a carbon layer formed therein.

본 발명에서는 상기 도자기유약으로 전체 중량 대비 1~3중량%를 포함할 것을 제안하나, 가장 바람직하게는 물토 0.8중량%, 석회석 0.8중량%, 재 0.4중량%를 혼합할 것을 제안하고 있다. The present invention proposes to include 1 to 3% by weight relative to the total weight of the porcelain glaze, but most preferably, 0.8% by weight of water, 0.8% by weight of limestone, and 0.4% by weight of ash.

이상과 같은 본 발명에 따르면, 목분과 목질이 탄화된 탄소체 분말을 함께 포함하면서 도자기유약을 혼합한 상태의 조성물을 성형함으로 산화염만으로 소성시켜도 내부에 탄화된 탄소층을 형성할 수 있게 되는 바, 경제적이면서 간편하게 이중구조를 갖는 카본 도자 조형물을 완성할 수 있게 된다.According to the present invention as described above, by shaping the composition of the ceramic powder mixed with wood powder and wood carbonized carbon powder together, it is possible to form a carbonized carbon layer even if the calcination only by oxidizing salt, It is possible to complete a carbon ceramic sculpture having a dual structure economically and simply.
