도 1은 실시예 및 비교예의 세라믹 단열패널의 고온 단열 성능을 평가하기 위한 장치를 나타낸 것이다. Fig. 1 shows an apparatus for evaluating the high-temperature insulation performance of the ceramic thermal insulation panels of the examples and the comparative examples.
이하, 일구현예에 따른 상온 성형 세라믹 단열 패널용 조성물, 이로부터 형성된 상온 성형 세라믹 단열 패널 및 그 제조방법을 보다 상세하게 설명하기로 한다.Hereinafter, a composition for a room temperature molded ceramic thermal insulation panel according to an embodiment, a room temperature molded ceramic insulation panel formed from the composition, and a method for manufacturing the same will be described in detail.
물유리, 플라이 애쉬, 소석회, 산화철, 발포제 및 방수제를 포함하며, 상기 산화철의 함량이 조성물 총중량을 기준으로 하여 0.5 내지 2 중량%인 상온 성형 세라믹 단열패널용 조성물이 제공된다.There is provided a composition for a room temperature molded ceramic thermal insulation panel comprising water glass, fly ash, slaked lime, iron oxide, a foaming agent and a waterproofing agent, wherein the content of iron oxide is 0.5 to 2% by weight based on the total weight of the composition.
산화철은 착색제이므로 이를 조성물내에 부가하면 상온 성형 세라믹 단열패널의 색상을 원하는 바대로 구현할 수 있을 뿐만 아니라 세라믹 단열 패널의 강도가 매우 개선된다. 산화철은 예를 들어 Fe2O3, Fe3O4, FeO 등을 들 수 있고, 그 중에서도 (Fe2O3 또는 Fe2O3와 FeO의 혼합물)을 사용한다. 산화철은 사이즈가 50 내지 500nm 범위를 갖는다. 산화철이 구형 입자 형태를 갖는 경우에는 사이즈는 평균입경을 나타내고 산화철이 비구형 입자인 경우에는 장축 길이를 나타낸다. 산화철의 함량은 0.5 내지 2 중량%, 예를 들어 1 내지 1.5 중량%이다. 산화철의 함량 및 사이즈가 상술한 범위일 때 세라믹 단열 패널의 착색이 용이하게 이루질 뿐만 아니라 개선된 강도와 발포력을 갖는 세라믹 단열 패널을 용이하게 제조될 수 있다.Since iron oxide is a coloring agent, if it is added to the composition, the color of the room-temperature molded ceramic heat-insulating panel can be realized as desired, and the strength of the ceramic heat-insulating panel is greatly improved. Examples of the iron oxide include Fe 2 O 3 , Fe 3 O 4 and FeO, among which (Fe 2 O 3 or a mixture of Fe 2 O 3 and FeO) is used. The iron oxide has a size ranging from 50 to 500 nm. When iron oxide has a spherical particle shape, the size indicates an average particle diameter, and when iron oxide is non-spherical particle, it indicates a long axis length. The content of iron oxide is 0.5 to 2% by weight, for example, 1 to 1.5% by weight. When the content and the size of the iron oxide are within the above-mentioned range, the ceramic heat-insulating panel can be easily colored, and the ceramic heat-insulating panel having improved strength and foaming power can be easily manufactured.
또한 상온 성형 세라믹 단열패널용 조성물내에 산화철이 함유되면 세라믹 단열 패널 제조시 인가되는 마이크로파의 흡수 효율을 높여 반응시간을 줄일 수 있다. 이러한 산화철 이외에 Al2O3, CaO, SiO2, TiO2, MgO 중에서 선택된 하나 이상의 금속 산화물을 더 포함할 수 있다. 이러한 금속 산화물은 산화철과 마찬가지로 마이크로파의 흡수 효율을 높일 수 있다. 그리고 이러한 금속 산화물의 함량은 산화철 100 중량부를 기준으로 하여 0.01 내지 10 중량부 범위이다.In addition, when iron oxide is contained in the composition for a room temperature molded ceramic insulation panel, the absorption efficiency of the microwave applied in the production of the ceramic insulation panel can be increased and the reaction time can be reduced. In addition to the iron oxide, it may further include at least one metal oxide selected from Al 2 O 3 , CaO, SiO 2 , TiO 2 , and MgO. These metal oxides can increase the absorption efficiency of microwaves like iron oxide. The content of the metal oxide is in the range of 0.01 to 10 parts by weight based on 100 parts by weight of iron oxide.

Furthermore, since the raw material is aluminum, it is excellent in refractory heat resistance, rigidity and workability, and is widely used as a functional material.
물유리(Water Glass)는 수용성 규산염 중 가장 널리 사용되고 있는 무기 화합물이다. 물에 대한 용해성 때문에 물유리(Water Glass)로 불리어 지고 있다. 이는 알카리 금속이 이산화규소(SiO2)와 다양한 몰비로 결합한 화합물로써 규산나트륨(Sodium Silicate), 규산 칼륨(Potassium Silicate), 리튬 실리케이트(Lithium Silicate) 등이 있으며 자체적으로 10% 내지 30% 정도의 물을 포함하고 있다. 물유리(Water Glass)는 순도 높은 모래를 탄산나트륨(Na2CO3) 또는 탄산칼륨(K2CO3)과 함께 1100~1200?에서 용융시켜 만들어 진다.Water Glass is the most widely used inorganic compound among water-soluble silicates.

이하, 본 발명에 따른 세라믹 단열패널의 제조방법을 살펴보기로 한다.Hereinafter, a method for manufacturing a ceramic thermal insulation panel according to the present invention will be described.
먼저, 성형틀을 준비한다. 성형틀은 예를 들어 실리콘 소재 성형틀을 이용하거나 또는 실리콘 소재 코팅층을 갖는 성형틀을 사용한다. 이러한 성형틀을 이용하면 후술하는 마이크로파 조사 과정이 원할하게 진행될 수 있다. First, a mold is prepared. The forming mold may be a mold made of, for example, a silicon material, or a mold having a silicon material coating layer. When such a mold is used, the microwave irradiation process described below can proceed smoothly.
이어서 성형틀에 이형제를 도포한다. 이형제로는 실리콘 오일 등을 이용하며 이형제를 성형틀에 미리 도포해두면 성형틀에 완성된 세라믹 단열 패널을 성형틀로부터 분리해내기가 용이해진다.Then, the mold release agent is applied to the mold. Silicone oil or the like is used as the releasing agent, and if the releasing agent is previously applied to the forming mold, the completed ceramic insulating panel can be easily separated from the forming mold in the forming mold.
이형제가 도포된 성형틀에 보강용 메쉬를 넣고 본 발명의 상온 성형 세라믹 단열 패널용 조성물을 부가한다.The reinforcing mesh is placed in a mold having the mold release agent applied thereto, and the composition for a room temperature molded ceramic heat insulating panel of the present invention is added.
상온 성형 세라믹 세라믹 단열패널용 조성물은 하기 2단계에 따라 제조할 수 있다. The composition for a room-temperature-formed ceramic ceramic thermal insulation panel can be prepared by the following two steps.
먼저 고형분 분말인 플라이 애쉬, 소석회, 발포제 및 산화철을 혼합하여 혼합물을 얻는다. 이 혼합물에 물유리 및 방수제를 부가 및 고속으로 교반하여 제조한다. 상기 교반 및 혼합 시간은 예를 들어 5분 이하, 예를 들어 3분 이하 범위로 조절하는 것이 바람직하다. 그리고 교반은 고속으로 예를 들어 내지 rpm범위로 실시해야 발포를 원하는 범위로 제어할 수 있다. First, the mixture of fly ash, slaked lime, foaming agent and iron oxide is mixed with solid powder. Water glass and a waterproofing agent are added to this mixture and stirred at a high speed. The stirring and mixing time is preferably adjusted to a range of, for example, 5 minutes or less, for example, 3 minutes or less. And stirring is performed at a high speed, for example, in the range of rpm, so that the foaming can be controlled in a desired range.
상술한 바와 같이 세라믹 단열 패널 조성물이 제공된 성형틀 상부에 보강용 메쉬 및 이형지를 순차적으로 적층한다. 이형지는 성형틀로부터 완성된 세라믹 단열 패널 분리를 용이하게 해주는 역할을 한다. 그리고 보강용 메쉬는 세라믹 단열패널의 강도를 더 높여주는 역할을 한다. 보강용 메쉬로는 등의 재질로 이루어진 메쉬를 이용한다.As described above, the reinforcing mesh and the releasing paper are sequentially stacked on the mold frame provided with the ceramic heat insulating panel composition. The releasing paper serves to facilitate the separation of the ceramic insulating panel finished from the molding die. And the reinforcing mesh serves to increase the strength of the ceramic insulating panel. As the reinforcing mesh, a mesh made of a back material is used.
상기 결과물 상부에 발포 가이드가 설치된 덮게를 설치한다. 발포 가이드에는 이형지 또는 이형제와 공기 배출구가 구비되어 발포시 발생하는 압력 공기를 외부로 배출하여 세라믹 단열 패널의 평활도 특성이 우수하다.A covering provided with a foam guide is provided on the resultant product. The foaming guide is provided with releasing paper or a releasing agent and an air discharging port to discharge pressure air generated at the time of foaming to the outside, so that the flatness characteristic of the ceramic heat insulating panel is excellent.
이어서, 상온에서 발포를 실시한다. 발포 시간은 세라믹 단열 패널 조성물의 구성성분 등에 따라 가변적이지만 예를 들어 5분 내지 30분, 예를 들어 5분 내지 10분이다.Subsequently, foaming is carried out at room temperature. The foaming time is variable depending on the constituents of the ceramic insulation panel composition and the like, but is, for example, 5 minutes to 30 minutes, for example, 5 minutes to 10 minutes.
상기 덮게에는 발포 가이드가 설치되어 있어 상온 발포로 발생된 공기가 외부로 배출될 수 있다.Since the foam guide is provided on the cover, the air generated by the room temperature foaming can be discharged to the outside.
발포가 완료된 결과물에 마이크로파 장치를 이용하여 마이크로파(극초단파)를 30 내지 70W 조건으로 조사하여 경화 반응을 실시한다. 마이크로파를 조사하는 단계는 예를 들어 30분 이내, 예를 들어 20분 이내, 예를 들어 3분 내지 10분, 예를 들어 5분 내지 7분 동안 실시한다. 상술한 마이크로파의 조사로 경화 공정이 진행되면서 세라믹 단열 패널의 내부까지 수분이 건조되는 효과를 얻을 수 있다.After completion of the foaming, the resultant is irradiated with a microwave (microwave) at 30 to 70 W using a microwave apparatus to perform a curing reaction. The step of irradiating microwaves is carried out for example within 30 minutes, for example within 20 minutes, for example from 3 minutes to 10 minutes, for example from 5 minutes to 7 minutes. The effect of drying the moisture to the inside of the ceramic heat insulating panel can be obtained while the curing process is performed by the irradiation of the microwave.
경화반응이 끝나면 성형틀로부터 완성된 세라믹 단열 패널을 분리해낸다.After the curing reaction is complete, remove the finished ceramic insulation panel from the mold.
상기 세라믹 단열 패널의 적어도 일 면에는 아연판, 황토 함유 기판 등의 기판을 더 적층하여 세라믹 단열 구조체를 형성할 수 있다.A ceramic heat insulating structure can be formed by further laminating a substrate such as a zinc plate and a yellow earth containing substrate on at least one surface of the ceramic heat insulating panel.
상기 제5단계 이후에 마이크로파 조사, 근적외선 조사, 또는 자연 건조하는 단계를 더 포함할 수 있다. 이러한 단계를 더 거치면 세라믹 단열패널의 강도 등의 특성이 더 우수해질 수 있다.The method may further include a step of microwave irradiation, near-infrared irradiation, or naturally drying after the fifth step.
