이하, 본 발명을 상세히 설명하도록 한다. 본 발명은 다양한 변경을 가할 수 있고 여러 가지 형태를 가질 수 있으며 본 발명의 사상 및 기술 범위에 포함되는 모든 변경, 균등물 내지 대체물을 포함하는 것으로 이해되어야 한다.Hereinafter, the present invention will be described in detail. It is to be understood that the present invention includes various modifications, may have various forms, and include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.
본 발명의 일 실시예에 따른 친환경 규조토 트레이는 모두 무공해, 친환경 소재로만 구성되도록, 규조토 50 내지 70중량%, 석고 분말 25 내지 40 중량%, 천연섬유 5 내지 10 중량%를 포함하도록 제조되는 것이 바람직하다.The eco-friendly diatomaceous earth tray according to an embodiment of the present invention is preferably manufactured to contain 50 to 70% by weight of diatomaceous earth, 25 to 40% by weight of gypsum powder, and 5 to 10% by weight of natural fibers so that all of the eco-friendly diatomaceous earth trays are made of pollution-free and eco-friendly materials only. Do.
본 발명의 주성분인 규조토는 이미 널리 알려져 있고 산업적으로 유용하게 사용되고 있다. 이러한 규조토는 식물성 플랑크톤인 규조류의 단세포 생물이 퇴적하여 암석화한 것으로 SiO2가 80% 이상이며, 미세 기공으로 이루어진 경량의 천연 광물이다. 이러한 규조토의 특성으로 산업적으로 여과조제, 단열재, 흡수제로 이용되고 건축용으로는 유해 가스의 흡착·분해 및 탈취 성능을 이용하거나 불연이나 경량 및 친환경의 건축 소재의 재료 등으로 널리 활용되고 있다.Diatomaceous earth, which is the main component of the present invention, is already widely known and is usefully used industrially. Diatomaceous earth is a natural mineral with more than 80% SiO2, and is a lightweight natural mineral composed of fine pores, as single-celled organisms of diatoms, which are phytoplankton, are deposited and formed into rocks. Due to the characteristics of such diatomaceous earth, it is industrially used as a filter aid, insulation, and absorbent, and for construction, it is widely used as a material for adsorbing, decomposing, and deodorizing harmful gases, or as a material for non-flammable, lightweight, and eco-friendly building materials.
일반적으로 규조토는 채광을 하여 선별, 분쇄를 한 뒤 소성 과정을 거치면서 수분, 불순물을 재거하고 사용에 적합한 입도로 가공하는 과정을 거쳐 제조된다. 이렇게 가공된 규조토 분말은 규조토의 평균입경에 따라 물리적 성능이 달라지는데 규조토의 평균입경이 10 내지 100㎛인 것이 이용될 수 있고 바람직하게는 30 ~ 80㎛인 것이 비표면적 및 흡수율이 높아 유해 가스의 흡착·분해, 탈취 및 조습 기능이 뛰어나다.In general, diatomaceous earth is manufactured by mining, selecting, pulverizing, removing moisture and impurities during a firing process, and processing it into a particle size suitable for use. The diatomaceous earth powder processed in this way has a different physical performance depending on the average particle diameter of the diatomaceous earth. However, those with an average particle diameter of 10 to 100 μm may be used, and preferably 30 to 80 μm are high in specific surface area and absorption rate, so that harmful gases can be adsorbed. ·Excellent decomposition, deodorization and humidity control.
본 발명에 적합한 규조토는 최적의 성능을 발현하기 위해 흡수율이 180 ~ 250이고 평균입경이 30 ~ 80㎛인 규조토를 사용하는 것이 적합하다. 규조토 분말의 평균입경이 30 ㎛ 이하이면 분쇄 공정으로 인해 기공이 사라지게 되어 탈취나 흡수 효과가 저하되고, 평균입경이 80 ㎛이상이면 성형물의 기계적 강도가 저하될 수 있다. Diatomaceous earth suitable for the present invention is suitable to use diatomaceous earth having a water absorption rate of 180 ~ 250 and an average particle diameter of 30 ~ 80㎛ in order to express the optimum performance. If the average particle diameter of the diatomaceous earth powder is 30 µm or less, pores disappear due to the pulverization process, thereby reducing the deodorization or absorption effect, and if the average particle size is 80 µm or more, the mechanical strength of the molded product may decrease.
본 발명의 일 실시예에 따른 친환경 규조토 트레이는 규조토의 함량이 전체 조성물에서 50 내지 70중량%인 것이 바람직하다. 규조토의 사용량이 적으면 적을수록 탈취, 흡습, 조습 성능이 저하되고, 70중량% 이상의 함량이 되면 기계적 강도, 성형성이 나빠져 트레이의 내구성을 지속적으로 유지하기 어렵게 된다.In the eco-friendly diatomaceous earth tray according to an embodiment of the present invention, it is preferable that the content of diatomaceous earth is 50 to 70% by weight in the total composition. The smaller the amount of diatomaceous earth used, the lower the deodorization, moisture absorption, and humidity control performance is, and when the content exceeds 70% by weight, mechanical strength and moldability are deteriorated, making it difficult to continuously maintain the durability of the tray.
본 발명의 일 실시예에 따른 친환경 규조토 트레이는 무기 바인더(binder)를 포함하는데, 무기 바인더(binder)로서는 벤토나이트(bentonite), 카올리나이트(kaolinite), 할로이사이트(halloysite), 아타풀자이트 등의 점토 광물이나, 물유리(soluble glass), 석회, 석고, 시멘트(cement) 등을 사용할 수 있지만, 본 발명에서는 석고를 사용하는 것이 바람직하다.The eco-friendly diatomaceous earth tray according to an embodiment of the present invention includes an inorganic binder, and as the inorganic binder, clay minerals such as bentonite, kaolinite, halloysite, and attapulgite However, soluble glass, lime, gypsum, cement, etc. can be used, but it is preferable to use gypsum in the present invention.
석고(gypsum)는 황산 칼슘(CaSO4)을 주성분으로 하는 매우 부드러운 황산염 광물로, 석고를 약 190℃에서 가열하여 75% 정도의 수분을 제거한 후 분쇄한 석고 분말이 통상적으로 무기계 바인더로 많이 사용된다. Gypsum is a very soft sulfate mineral containing calcium sulfate (CaSO4) as a main component. Gypsum powder obtained by heating gypsum at about 190°C to remove about 75% of moisture and then pulverized gypsum powder is commonly used as an inorganic binder.
석고 분말에 석고 대비 최소 18 중량%의 물을 혼합하면 입자의 결정이 다시 결합하여 단단한 수산화칼슘의 황산염 상태로 돌아가 경화되는 과정을 통해 다른 조성물을 결합하는 바인더 기능을 발휘하는데, 이러한 경화과정 동안에 석고와 물이 발열반응을 하여 약 60도까지 가열될 수 있어, 다른 조성물과의 혼합 성형 과정에서 별도의 외부 에너지가 불필요하고 혼합 성형된 혼합물의 건조도 신속하게 수행되는 효과가 있다.When the gypsum powder is mixed with at least 18% by weight of water compared to gypsum, the crystals of the particles are recombined, returning to the hard calcium hydroxide sulfate state, and curing, thereby exerting a binder function to bind other compositions. Since water undergoes an exothermic reaction and can be heated up to about 60 degrees, there is an effect that separate external energy is not required in the process of mixing and molding with other compositions, and drying of the mixed-molded mixture is quickly performed.
따라서, 본 발명과 같이 수 백도 내지 수 천도의 고온 소결과정이 불필요한 경우에는 석고를 바인더로 사용함으로써 별도의 연료 사용이 없이 석고의 발열 에너지만으로 본 발명의 조성물들을 혼합 성형할 수 있으므로 본 발명의 제조과정에서 연소 유해물질의 배출이 감소하게 된다.Therefore, when the high-temperature sintering process of several hundred to several thousand degrees is unnecessary, as in the present invention, by using gypsum as a binder, the compositions of the present invention can be mixed and molded only with the heating energy of gypsum without using a separate fuel. In the process, the emission of harmful substances from combustion is reduced.
본 발명에서는 석고 분말이 전체 조성물에서 25 내지 40 중량% 범위가 바람직한데, 석고 분말 25 중량% 이하이면 바인딩 효과가 저하되고 석고 분말 40 중량% 이상이면 규조토 함량이 감소하여 탈취나 흡습 효과가 감소하게 된다. In the present invention, the gypsum powder is preferably in the range of 25 to 40% by weight in the total composition. If the gypsum powder is 25% by weight or less, the binding effect is reduced, and if the gypsum powder is 40% by weight or more, the diatomaceous earth content decreases, thereby reducing the deodorization or moisture absorption effect. do.
한편, 본 발명에서 벤토나이트(bentonite), 특히 활성 벤토나이트를 석고와 같이 무기계 바인더로 사용할 수 있는데, 벤토나이트는 바인더 기능을 하는 동시에 악취성분의 흡착 능력을 가지므로 규조토의 탈취 효과를 한층 더 향상시킬 수 있다. On the other hand, in the present invention, bentonite, especially activated bentonite, can be used as an inorganic binder like gypsum. Since bentonite functions as a binder and has the ability to adsorb odor components, the deodorizing effect of diatomaceous earth can be further improved. .
예를 들어, 전체 조성물에서 석고 분말을 15 내지 30 중량% 범위로 줄이고, 벤토나이트를 10 내지 20 중량% 범위로 추가함으로써 벤토나이트의 탈취 효과가 규조토의 탈취 효과와 상승 작용을 하여 친환경 규조토 트레이의 탈취 성능을 한층 더 향상시킬 수 있다.For example, by reducing gypsum powder in the range of 15 to 30% by weight in the total composition and adding bentonite in the range of 10 to 20% by weight, the deodorizing effect of bentonite is synergistic with the deodorizing effect of diatomaceous earth, and the deodorizing performance of the eco-friendly diatomaceous earth tray Can further improve.
또한, 본 발명에서는 탈취 촉매로서 전체 조성물 기준 0.1 내지 0.2 중량％ 정도의 이산화 망간을 첨가하여 암모니아, 황화수소나 메틸 메르캅탄과 같은 악취 성분을 분해할 수 있다. 이산화 망간은 독성이 낮고 염가이며, 산화티탄과 같은 광촉매와는 달리 빛이 없어도 탈취 효과를 나타내므로 밀폐된 실내 공간의 탈취제로 적합하고, 또한 이산화 망간은 촉매 탈취제이므로 화학 탈취제나 활성탄과 같은 물리적 탈취제와 달리 탈취 효과가 반영구적으로 지속할 수 있다. In addition, in the present invention, as a deodorization catalyst, about 0.1 to 0.2% by weight of manganese dioxide can be added to decompose odor components such as ammonia, hydrogen sulfide and methyl mercaptan. Manganese dioxide has low toxicity and is inexpensive, and unlike photocatalysts such as titanium oxide, it exhibits a deodorizing effect even without light, so it is suitable as a deodorant for a closed indoor space.Also, manganese dioxide is a catalyst deodorant, so a physical deodorant such as a chemical deodorant or activated carbon. Unlike this, the deodorizing effect can persist semi-permanently.
