본 발명은 인체에 무해하고 흡음 및 방음 특성이 우수하고 각종 물성이 우수하여 바닥재, 천정재, 내장재의 건축자재로 적합한 경량 발포 세라믹체 및 이의 제조방법에 관한 것이다.The present invention relates to a lightweight foamed ceramic body which is harmless to the human body, has excellent sound absorption and soundproofing properties, and various physical properties, which is suitable for building materials of flooring materials, ceiling materials and interior materials, and a method of manufacturing the same.

발포세라믹은 세라믹을 발포시켜 초경량의 인공골재 및 석재를 대체할 수 있는 재료로 각광받고 있다. 상기 발포세라믹 제조 기술은 일반점토와 황토, 제올라이트(Zeolite)와 알루미나 등 몇 가지의 원료를 용도에 맞게 배합하는 기술을 바탕으로 강도발현, 기공의 수와 크기, 제품의 형태와 크기의 자유로운 조정이 가능한 특징이 있다. 또한 원료의 배합과 소성(燒成)기술을 바탕으로 비중도 0.4 내지 0.9까지 자유롭게 제조할 수 있다.Foam ceramics are in the limelight as a material that can replace ultra-lightweight artificial aggregates and stones by foaming ceramics. The foamed ceramic manufacturing technology is based on the technology of formulating several raw materials, such as clay, ocher, zeolite and alumina, according to the application, the strength, the number and size of pores, free adjustment of the shape and size of the product There are possible features. In addition, the specific gravity can be freely produced up to 0.4 to 0.9 based on the blending and firing technology of the raw materials.

발포세라믹 제조의 가장 큰 기술적 가치는 원료의 배합과 소성과정, 즉 예열대(豫熱帶)에서의 예열곡선과 용융점에서의 용융시간 조정, 발포가스의 통제, 냉각구간에서의 온도 수율(

Figure 112008076651917-PCT00001
度受
Figure 112008076651917-PCT00002
) 조정으로 요약된다. 또한 각 단계별 시간과 온도의 조정을 통한 비중 및 크기, 형태, 기포의 인위적 조작이 가능한 특징이 있다.The greatest technical value of foamed ceramic production is the blending and firing process of raw materials, that is, preheating curve in preheating zone and melting time at melting point, control of foaming gas, temperature yield in cooling section (
Figure 112008076651917-PCT00001
度 受
Figure 112008076651917-PCT00002
) Is summarized as an adjustment. In addition, it is possible to artificially manipulate specific gravity, size, shape, and bubbles by adjusting the time and temperature for each step.

발포세라믹은 비중 0.5 수준의 초경량 인공골재 및 판형의 석재를 대체할 수 있는 마감재, 가공 및 절단의 용이성을 이용한 목재대체재 등으로 활용이 가능하다.Foam ceramics can be used as finishing materials that can replace ultra-lightweight artificial aggregates and plate-shaped stones with a specific gravity of 0.5, and wood substitutes with ease of processing and cutting.

또한 제조된 발포세라믹을 이용하여 마블링(Marbling) 및 상감(Inlaying) 타일 및 장식용 건축자재로서도 활용이 유망하다. 아울러 발포성 소재 특유의 흡음, 단열, 경량성을 이용한 다양한 용도로서 응용이 가능하다In addition, it is promising to be used as marbling and inlaying tiles and decorative building materials using the manufactured foam ceramics. In addition, it can be applied to various applications using sound absorption, heat insulation, and light weight unique to foam materials.

종래 폐자원을 이용하여 경량 발포 세라믹을 개발했지만, 생산성에 맞지 않는 복잡한 제조 공정으로 제품의 가격이 너무 높은 폐단이 따랐다. 또한, 종래 발포세라믹은 유리화 온도가 높고, 발포 팽창시 과도한 기공으로 불량률이 높은 단점이 따른다.Conventionally, lightweight foamed ceramics have been developed using waste resources, but a complicated manufacturing process that is not suitable for productivity has resulted in a too high price of products. In addition, conventional foamed ceramics have a disadvantage in that the vitrification temperature is high and the defect rate is high due to excessive porosity during foam expansion.

폐자원의 이용이라는 측면도 있지만, 이 역시 오랜 시간의 경과함에 따라 인체에 유해한 물질이 방출되는 것으로 알려지고 있다. 현재 기술의 발달로 단열, 방음의 효과를 나타내어 주는 자재가 많이 보급되고 있지만, 대부분 열에 약한 특성이 있고 화재 발생시 유독 가스를 발생시키는 주요 원인이 되고 있다.Although there are aspects of the use of waste resources, this is also known to release substances harmful to the human body over time. With the development of current technology, many materials that show the effect of insulation and sound insulation have been widely used, but most of them have weak characteristics in heat and are a major cause of generating toxic gases in case of fire.

무엇보다 기존의 흡음 재료는 인체에 유해한 석면을 사용하기 때문에 석면 입자가 외부로 유출되어 폐암을 일으키는 원인이 되기도 한다.Above all, existing sound absorbing materials use asbestos, which is harmful to the human body, causing asbestos particles to leak out and cause lung cancer.

그리고 소음 공해의 문제 해결은 실제 소음원과 수음원의 저감에는 한계가 있어, 소음 전달 경로의 차단 방법을 사용하지만, 비용이 많이 들고, 설치 후 시간이 경과하면 그 성능이 저하된다.The problem of noise pollution is that there is a limit to the reduction of the actual noise source and the sound source, and the noise transmission path blocking method is used, but the cost is high, and the performance decreases after the installation.

기술적 과제Technical challenge

본 발명의 목적은 인체에 무해하고 흡음 및 방음 특성이 우수하고 내균열성, 내마모성, 강도, 동결융해성, 흡수성 및 접착성이 적합하여 건축자재로 적합한 발포 세라믹체 및 이의 제조방법을 제공하는 것이다.It is an object of the present invention to provide a foamed ceramic body suitable for construction materials and a method for manufacturing the same, which are harmless to human body, have excellent sound absorption and soundproofing properties, and are suitable for cracking resistance, abrasion resistance, strength, freeze melting, absorbency and adhesion. .

기술적 해결방법Technical solution

상기 목적을 달성하기 위해, 본 발명은 화산재, 점토, 알루미나, 규석, 장석 및 발포제를 포함하는 경량 발포 세라믹체를 제공한다.In order to achieve the above object, the present invention provides a lightweight foamed ceramic body comprising volcanic ash, clay, alumina, silica, feldspar and blowing agent.

또한 본 발명은 화산재, 점토, 알루미나, 규석, 장석 및 발포제를 혼합하여 얻어진 혼합 분말을 점토틀에 주입한 후 1000 내지 1300℃에서 발포 소성하여 제조하는 경량 발포 세라믹체의 제조방법을 제공한다.The present invention also provides a method for producing a lightweight foamed ceramic body prepared by injecting a mixed powder obtained by mixing volcanic ash, clay, alumina, silica, feldspar and blowing agent into a clay mold and then foaming and firing at 1000 to 1300 ° C.

이하 본 발명을 더욱 상세하게 설명한다.Hereinafter, the present invention will be described in more detail.

본 발명에 따른 경량 발포 세라믹체는 인체에 무해할 뿐만 아니라, 흡음 및 방음 특성이 우수하고, 단열성 및 불연성을 비롯한 각종 물성이 우수하고, 곰팡이 저항성, 탈취 및 습기 투과성이 높아 인체에 무해하여 건축자재로 적합하다.The lightweight foamed ceramic body according to the present invention is not only harmless to the human body, but also has excellent sound absorption and soundproofing properties, various physical properties including heat insulation and non-combustibility, and is high in mold resistance, deodorization and moisture permeability, and therefore harmless to building materials. Is suitable as.

상기 경량 발포 세라믹체는 화산재, 점토, 알루미나, 규석, 장석 및 발포제를 포함하는 경량 발포 세라믹체를 포함한다.The lightweight foamed ceramic body includes a lightweight foamed ceramic body including volcanic ash, clay, alumina, silica, feldspar and a blowing agent.

화산재는 고열 고압 가스 에너지에서 천연 소생 다공질로 이루어진 쇠설질이 퇴적된 것으로 화산 폭발시 1600 내지 1800℃로 천연 고온 소성되어 기공이 많고 가벼우며, 견고하여 흡음율 및 보온성이 우수할 뿐만 아니라 인체에 유익한 원적외선을 방출한다.Volcanic ash is a deposit of natural resuscitation porous iron from high-temperature high-pressure gas energy. It is naturally high-temperature calcined at 1600-1800 ℃ during volcanic eruption, so it has a lot of pores and lightness, it is strong, and its sound absorption and warmth are excellent. Emits.

본 발명에서 상기 화산재는 50 내지 70 중량%로 포함되며, 만약 그 함량이 상기 범위 미만이면 흡음율이 저하되는 문제가 있고, 상기 범위를 초과하면 경량 세라믹 발포체의 강도가 저하될 우려가 있으므로, 상기 범위 내에서 적절히 사용하는 것이 바람직하다.In the present invention, the volcanic ash is included in the range of 50 to 70% by weight, and if the content is less than the above range, there is a problem that the sound absorption is lowered. It is preferable to use suitably within.

점토는 경량 발포 세라믹체 제조시 발포시 발포체가 균일한 셀 크기를 갖게 하고, 소성시 재료의 점성을 증가시켜 강도를 향상시킨다. 상기 점토는 본 발명에서 특별히 한정하지 않으며, 이 분야에서 통상적으로 사용되는 점토가 사용될 수 있으며, 대표적으로 카올린족 광물, 피로필라이트(Pyrophyllite, 엽납석), 몬모릴로나이트(Montmorillonite), 마이카(Mica, 운모), 일라이트(Illite), 및 탈크(Talc, 활석)로 이루어진 군에서 선택된 1종 이상이 가능하다.Clay allows the foam to have a uniform cell size when foaming in the manufacture of lightweight foam ceramics, and increases the viscosity of the material upon firing to improve strength. The clay is not particularly limited in the present invention, and clays commonly used in this field may be used. Representatively, kaolin minerals, pyrophyllite (Pylophyllite), montmorillonite, and mica (Mica, mica) may be used. ), Illite, and Talc (Talc, talc) may be used.

본 발명에 따른 점토는 10 내지 30 중량%로 포함되며, 만약 그 함량이 상기 범위 미만이면 발포체의 셀 크기 제어 또는 재료의 점성 조절이 미비하여 기공을 가지지 않는 치밀한 구조의 경량 발포 세라믹체가 제조된다. 이와 반대로, 상기 범위를 초과하면 점성이 과도하게 증가하여 소성시 경량 발포 세라믹체의 유리질 형성이 미비하여 강도가 저하되는 문제가 발생하므로 상기 범위 내에서 적절히 사용하는 것이 바람직하다.The clay according to the present invention is contained in 10 to 30% by weight, and if the content is less than the above range, a compact foamed ceramic body having a compact structure having no pores due to insufficient cell size control or viscosity control of the foam is produced. On the contrary, if it exceeds the above range, the viscosity is excessively increased, so that the glassy formation of the lightweight foamed ceramic body during firing is insufficient, resulting in a problem that the strength is lowered.

알루미나는 내열성, 전기 절연성, 및 기계적 성질이 우수하고 화학적으로 중성으로서 매우 안정하며 여러 가지 화학 약품에 대해 강한 내식성을 나타내어 건축자재로 많이 사용되고 있다.Alumina is widely used as a building material because it has excellent heat resistance, electrical insulation, mechanical properties, is chemically neutral, very stable, and exhibits strong corrosion resistance against various chemicals.

본 발명에서 상기 알루미나는 0.5 내지 10 중량%로 포함되며, 만약 그 함량이 상기 범위 미만이면 상기 효과를 얻을 수 없고, 상기 범위를 초과하면 상대적으로 규석을 비롯한 다른 성분의 함량이 저하되어 열팽창 계수가 증가하고, 발포 및 소성시 표면과 내부 사이의 온도 차이로 인해 균열 등이 발생하게 되므로, 상기 범위 내에서 적절히 사용하는 것이 바람직하다.In the present invention, the alumina is contained in 0.5 to 10% by weight, if the content is less than the above range can not be obtained the effect, if it exceeds the above range, the content of other components, including silica, is relatively low, the coefficient of thermal expansion Increasing and cracking occurs due to the temperature difference between the surface and the inside during foaming and firing, so it is preferable to use the above within the above range.

규석은 발포 및 소성 공정시 낮은 온도에서 유리상을 형성하여 발생되는 가스(CO2)를 세라믹체 내부로 포집하여 폐기공(閉氣孔) 조직을 생성시켜 세라믹체의 강도 및 발포를 균일하게 한다.Silica collects gas (CO 2 ) generated by forming a glass phase at a low temperature during the foaming and sintering process into the ceramic body to form a waste hole structure, thereby making the strength and foaming of the ceramic body uniform.

본 발명에서는 상기 규석을 15 내지 20 중량%로 사용한다. 만약, 그 함량이 상기 범위 미만이면 세라믹의 열팽창 계수가 높게 되어, 가열 발포된 생성들이 냉각될 때 이것의 표면부와 내부 사이의 온도 차이로 인해 균열 등이 발생하게 되고, 이와 반대로 상기 범위를 초과하면 과대 발포를 유발하므로, 상기 범위 내에서 적절히 사용하는 것이 바람직하다.In the present invention, the silica is used at 15 to 20% by weight. If the content is less than the above range, the coefficient of thermal expansion of the ceramic becomes high, and when the heat-expanded products are cooled, a crack or the like occurs due to a temperature difference between the surface portion and the inside thereof, and vice versa. Since lower foaming will cause excessive foaming, it is preferable to use suitably within the said range.

장석은 고온에서 점성이 있는 액체 특성을 나타내어, 본 발명의 소성 공정에서 재료에 점성을 부여하여 각 조성간 결합을 높이는 역할을 한다. 상기 장석은 본 발명에서 특별히 한정하지 않으며, 이 분야에서 통상적으로 사용되는 장석이 사용될 수 있으며, 대표적으로 칼리장석(orthoclase, 정장석), 소오다 장석(Albite, 조장석), 석회 장석(Amorthite), 및 바륨장석(Calsian)으로 이루어진 군에서 선택된 1종 이상이 가능하다.Feldspar exhibits a viscous liquid property at high temperatures, thereby imparting viscosity to the material in the firing process of the present invention and serves to enhance the bonds between the compositions. The feldspar is not particularly limited in the present invention, feldspar commonly used in this field may be used, and typically, feldspar (orthoclase, feldspar), soda feldspar (Albite, feldspar), lime feldspar (Amorthite), and At least one selected from the group consisting of barium feldspar is possible.

본 발명에서는 상기 장석을 5 내지 30 중량%로 사용한다. 만약, 그 함량이 상기 범위 미만이면 소성시 재료의 점성이 지나치게 증가하고, 이와 반대로 상기 범위를 초과하게 되면 점성이 너무 낮아 과대 발포를 유발하므로, 상기 범위 내에서 적절히 사용하는 것이 바람직하다.In the present invention, the feldspar is used at 5 to 30% by weight. If the content is less than the above range, the viscosity of the material at the time of baking is excessively increased. On the contrary, if the content exceeds the above range, the viscosity is too low to cause excessive foaming, and therefore, it is preferable to use it properly within the above range.

발포제는 기포를 함유한 재료를 만들기 위한 첨가제로, 본 발명에 따른 경량 발포 세라믹체의 발포도 및 기공도를 조절하여 적절한 발포 특성을 갖도록 한다. 사용가능한 발포제는 본 발명에서 특별히 한정하지는 않으며, 대표적으로 탄화규소, 질화규소, 질화붕소, 산화안티몬, 산화비소, 카본블랙, 탄산나트륨, 탄산칼슘, 탄산마그네슘, 백운석 및 물 유리로 이루어진 군에서 선택된 1종 이상이 가능하다.The blowing agent is an additive for making a material containing bubbles, and adjusts the degree of foaming and porosity of the lightweight foamed ceramic body according to the present invention to have appropriate foaming properties. The foaming agent that can be used is not particularly limited in the present invention, and is typically selected from the group consisting of silicon carbide, silicon nitride, boron nitride, antimony oxide, arsenic oxide, carbon black, sodium carbonate, calcium carbonate, magnesium carbonate, dolomite and water glass. The above is possible.

상기 발포제는 2 내지 10 중량%로 사용한다. 만약 그 함량이 상기 범위 미만이면 충분한 발포가 이루어지지 않아 물성이 저하되고, 이와 반대로 상기 범위를 초과하게 되면 과도한 발포로 인한 물성 저하가 일어나므로, 상기 범위 내에서 적절히 조절하여 사용한다.The blowing agent is used in 2 to 10% by weight. If the content is less than the above range, sufficient foaming is not performed, and thus physical properties are lowered. On the contrary, if the content is exceeded, the physical properties are lowered due to excessive foaming.

이러한 경량 발포 세라믹체는 화산재, 점토, 알루미나, 규석, 장석 및 발포제를 혼합한 후, 점토틀에 주입한 후 1,000℃ 내지 1,300℃ 에서소성하여 제조한다.The lightweight foamed ceramic body is prepared by mixing volcanic ash, clay, alumina, silica, feldspar and blowing agent, and then injecting it into a clay mold and firing at 1,000 ° C to 1,300 ° C.

볼밀기에 화산재, 점토, 알루미나, 규석, 장석 및 발포제 각각의 각각의 원료를 주입한 후, 입도가 80 내지 100 mesh가 되도록 균일하게 분쇄하는 볼밀 공정을 수행한다. 상기 입도는 경량 발포 세라믹체의 밀도 및 다공성에 영향을 주게 되는데, 입도가 균일할수록 균일한 발포가 이루어지고 소성 공정 후 더욱 안정적인 결정형의 구조를 갖게 된다.After injecting the raw materials of each of the volcanic ash, clay, alumina, silica, feldspar, and blowing agent into the ball mill, a ball mill process of uniformly pulverizing the particles to 80 to 100 mesh is performed. The particle size affects the density and porosity of the lightweight foamed ceramic body. The more uniform the particle size is, the more uniform foaming is achieved and a more stable crystalline structure after the firing process is obtained.

이때 보다 균일한 혼합을 이루기 위해 화산재, 점토, 알루미나, 규석, 장석 및 발포제 각각의 원료를 균일한 혼합을 이루기 위해 필요에 따라 전분쇄 과정을 수행할 수 있다.At this time, in order to achieve a more uniform mixing, the raw material of each of the ash, clay, alumina, silica, feldspar and blowing agent can be carried out a starch grinding process as necessary to achieve uniform mixing.

다음으로, 볼밀 공정 후 얻어진 혼합 분말을 발포 및 소성을 위해 점토틀에 주입한다. 상기 점토틀은 발포 및 소성 공정시 균일한 기공을 형성하고, 내부와 외부간의 열의 온도 차이를 낮추는 효과가 있다. 이러한 점토틀은 본 발명에서 한정하지 않으며, 제작하고자 하는 건축자재의 형상에 적합하도록 제작할 수 있으며, 점토틀의 색상과 디자인, 용도에 따른 활용 방안이 크다고 할 수 있다.Next, the mixed powder obtained after the ball mill process is poured into the clay bottle for foaming and firing. The clay bottle has an effect of forming uniform pores during the foaming and firing process, and lowering the temperature difference of heat between the inside and the outside. Such a clay bottle is not limited in the present invention, it can be produced to suit the shape of the building material to be produced, it can be said that the utilization method according to the color, design, and use of the clay bottle.

이어서, 상기 혼합 분말을 포함하는 소성물을 소성로로 이송하여 1,000 내지 1,300℃ 에서 0.5 내지 2 시간 동안 유지하여 발포 및 소성 공정을 수행하여 경량 발포 세라믹체와 겉표면 천연 유리질 피막을 동시에 제조 가능하게 한다.Subsequently, the calcined product including the mixed powder is transferred to a calcining furnace and maintained at 1,000 to 1,300 ° C. for 0.5 to 2 hours to perform a foaming and calcining process to simultaneously produce a lightweight foam ceramic body and a surface natural glass coating. .

일단 소성로 내 온도가 상승하게 되면 유리질과 결정질이 생성되고 하기 반응식에서 제시한 바와 같이 발포제(예 탄화규소)의 반응이 진행되어 점토틀 내 혼합분말의 발포가 진행되어 부풀어 오르며, 소성온도에서 소성하여 경량 발포 세라믹체가 제조된다. Once the temperature in the kiln is raised, glassy and crystalline are formed, and the reaction of the blowing agent (eg silicon carbide) proceeds as shown in the following reaction formula, and the foaming of the mixed powder in the clay bottle proceeds to swell, and then fired at the firing temperature. Lightweight foamed ceramic bodies are produced.

상기 경량 발포 세라믹체는 적절한 온도와 원료 배합의 조건이 서로 상응할 때, 기공구조의 내부면과 유리질 피막으로 싸여진 외부면의 형태로 생성된다. 상기 경량 발포 세라믹체의 표면(외부면)은 소성시 표면 유리질 피막의 두께는 조건에 따라 다르나 수 mm로, 실시예 1의 경우 약 1 mm 정도를 가진다. 상기 표면의 유리질 피막은 종래 타일의 제조 과정 중 유약을 시유하여 얻게 되는 구조로, 본 발명에서는 별도의 유약 처리 없이 특정 범위의 조성을 이용하여 제조함으로써 적절한 온도와 소지의 배합에서 자연히 유리질 표면을 얻는다. 이는 공정을 단축시켜 작업이 편리해지고 원가도 저감되는 잇점이 있다.The lightweight foamed ceramic body is produced in the form of an inner surface of the pore structure and an outer surface wrapped with a glassy film when the appropriate temperature and the conditions of the raw material mixture correspond to each other. The surface (outer surface) of the lightweight foamed ceramic body has a thickness of the surface glassy film during firing, depending on conditions but several mm, in the case of Example 1, about 1 mm. The glass coating on the surface is a structure obtained by applying a glaze during the manufacturing process of the conventional tile, in the present invention, by using a specific range of composition without a separate glaze treatment to obtain a naturally glassy surface at the appropriate temperature and body combination. This has the advantage of shortening the process, making the operation convenient and reducing the cost.

Moreover, the sound insulation and sound absorption properties are superior to those of conventional cement or building materials. In particular, it is excellent in mold resistance and moisture permeability, and it does not generate mold and has excellent deodorizing effect. Therefore, it can be used for various building materials.
