Description

황토 타일 제조방법{Method for Manufacturing Loess Tile}Method for Manufacturing Loess Tile

본 발명은 건축물의 바닥 또는 벽체에 부착 시공하는 황토타일에 관한 것으로, 특히 운반 시공 등 취급 시에 쉽게 깨어지지 않고 구조적으로 견고하게 만들 수 있는 황토타일 제조방법에 관한 것이다.The present invention relates to an ocher tile attached to a floor or a wall of a building, and more particularly, to a method of manufacturing an ocher tile that can be structurally solid without being easily broken during handling such as transportation.

황토 1스푼에는 약 2억 마리의 미생물이 살고 있어 다양한 효소들이 순환 작용을 일으키고 있다. 예로부터 황토는 살아있는 생명체라 하여 엄청난 약성을 가진 무병장수의 흙으로 사용되어 왔다. About a hundred million microorganisms live in one spoon of loess, causing various enzymes to circulate. Since ancient times, loess has been used as a living, lifeless soil with tremendous weakness.

황토는 다량의 탄산칼슘(CaCO3)을 가지고 있는데, 이 탄산칼슘에 의해 물을 가하면 찰흙으로 변하는 성질이 있다. 황토는 실리카(SiO2), 알루미나(Al2O3), 철분, 마그네슘(Mg), 나트륨(Na), 칼리 등으로 구성되어 있다. 이러한 성분비와 다양한 효소들로 조성된 황토는 동-식물의 성장에 꼭 필요한 원적외선을 다량 방사하므로 일명 황토를 살아있는 생명체라 일컫는다. Ocher has a large amount of calcium carbonate (CaCO 3 ), which is converted into clay when water is added by the calcium carbonate. Ocher is composed of silica (SiO 2 ), alumina (Al 2 O 3 ), iron, magnesium (Mg), sodium (Na), and kali. Ocher composed of such an ingredient ratio and various enzymes emits a large amount of far-infrared rays necessary for the growth of animals and plants, so it is called a living organism.

황토는 표면이 넓은 벌집구조로 수많은 공간이 복층구조를 이루고 있다. 이 스펀지 같은 구멍 안에는 원적외선이 다량 흡수, 저장되어 있어 열을 받으면 발산 하여 다른 물체의 분자활동을 자극한다. 원적외선은 세포의 생리작용을 활발히 하고, 열에너지를 발생시켜 유해 물질을 방출하는 광전효과가 있다. Ocher is a honeycomb structure with a large surface, and a large number of spaces have a multi-layer structure. In this sponge-like hole, far-infrared rays are absorbed and stored in a large amount, and radiate when heated to stimulate molecular activity of other objects. Far-infrared rays have a photoelectric effect that activates the physiology of cells and generates thermal energy to release harmful substances.

또 항균, 탈취, 습기조절력으로 건물내부를 쾌적하게 하며, 축열 작용이 높아 난방비가 절약되며, 인체에 유해한 곰팡이와 같은 각종 균류의 서식을 방지한다.In addition, the interior of the building is comfortable with antibacterial, deodorizing, and moisture control, and the heat storage effect is high, which saves heating costs and prevents the infestation of various fungi, such as mold, which is harmful to the human body.

이렇게 황토가 인체에 유익하다는 것이 알려져, 다양한 황토 상품이 무수히 쏟아져 나오고 있으며, 현대식 건축에도 황토를 다시 활용하기 시작하고 있다. 대표적인 것이 황토벽돌인데, 황토의 기능을 발휘하기 위해서는 불에 굽는 소성 과정을 배제하고 자연건조만 해야 한다. It is known that ocher is beneficial to the human body, and various ocher products are pouring out, and it is starting to use ocher again in modern architecture. A typical example is the ocher brick, and in order to function as ocher, natural drying should be performed without the baking process.

그러나 자연건조만으로는 강인한 강도가 보장되지 않고, 물에 젖으면 황토가 녹아 쉽게 부서져 건축용으로 쓰기 힘들다. 따라서 타일 같이 얇고 단단해야 하는 경우에는 황토를 적용시킨 예가 거의 없는 실정이다.However, natural drying alone does not guarantee robust strength, and when wet, the ocher melts and is easily broken, making it difficult to use for construction purposes. Therefore, in the case of being thin and hard as a tile, there are few examples of applying ocher.

또한 현재 국내시중에서 실시되고 있는 황토 바닥의 시공은 황토성분이면서 잡석들이 섞여 있으며 입자도 고르지 못한 흙을 마구 바닥에 깔고 물로 반죽하여 바닥 표면만을 고르게 골라서 황토바닥 시공을 해오고 있는 실정이어서 시공 시에 바닥을 고르게 고르는 작업도 어렵거니와 잡석마저 혼합되어 있어서 원적외선이 방출되는 양이 감소될 뿐만 아니라 결국 바닥의 두께만 증가시킬 뿐 건강에 좋다는 원적외선 효과는 없으면서 시공비와 아파트 분양가 등만 상승시키면서 입주 소비자들만 부담을 가중하게 되어 기만당하는 것 같은 결과가 초래하게 되는 결점이 있다.In addition, the construction of ocher floor is currently carried out in the domestic market. It is the fact that the construction of the ocher floor is carried out by evenly arranging the floor surface by spreading the clay with uneven soil and uneven particles on the harness floor and kneading with water. Even flooring is difficult to work with, and even rubble reduces the amount of far-infrared rays emitted, and only increases the thickness of the floor, but it does not increase the cost of far-infrared rays. There is a drawback to the consequences of being weighted and deceived.

상기한 결점을 해결하고자 특허등록번호 제0216568호에서는 잡석이 혼합된 황토를 수중에 분산시켜서 비중이 무거운 잡석이나 금속 등을 침전시키면서 미세하게 분쇄되게 한 다음 황토만을 분리하여 다시 교반하면서 더욱 미세한 현탁액으로 한 후 황토만을 침전시켜 분리한 다음 어느 정도 건조되었을 때 다양한 크기의 타일형태로 성형하여 합성수지필름 포장지에 넣고 진공 포장하여 제조하는 방법을 제시하고 있다.In order to solve the above-mentioned defects, Patent Registration No. 0216568 disperses the mixed clay in water to finely crush it while precipitating heavy rubble or metal, and then separates only the yellow soil and stirs it to a finer suspension. After sedimentation and separation of only ocher, and then dried to some extent to form a tile of various sizes and put into a synthetic film wrapping paper to propose a method of manufacturing by vacuum packaging.

그러나 이와 같이 구성되는 황태 타일은 접착제 또는 구조재가 부가되지 않고 황토만으로 형성되는 것이므로 취급 시에 파손될 우려가 있으며 물을 분사시킬 경우 쉽게 분해되는 문제점이 있으며, 합성수지필름 포장지에 진공상태로 보관하여야만 하기 때문에 보관이 어렵고 보관비용이 증대되는 문제가 있다.However, since the yellow tiles formed as described above are formed only by loess, without any adhesive or structural material added, there is a risk of breakage during handling, and there is a problem of being easily decomposed when water is sprayed. There is a problem that the storage is difficult and the storage cost is increased.

따라서 본 발명이 이루고자 하는 기술적 과제는 상술한 문제점을 해결할 수 있는, 즉 강도가 높고, 물에 잘 견디며 보관이 용이한 황토 타일 제조방법을 제공하는 것이다.

<실시예><Example>

정제된 고운 분말의 황토에 하기 표 1에서와 같은 물 내지 고분자 수용액을 약 100:5 중량비로 혼합하여 지름 1인치, 높이 1인치의 원기둥 모양의 황토 시편 타일을 제조하였다. 이와 같이 제조된 시편 타일에 대하여 압축 강도를 테스트하여 하기 표 1에 나타냈다. A cylindrical ocher specimen tile having a diameter of 1 inch and a height of 1 inch was prepared by mixing water to a polymer aqueous solution as shown in Table 1 in a weight ratio of about 100: 5 to the refined fine powder loess. The compressive strength of the specimen tiles thus prepared was tested and shown in Table 1 below.

상기 표 1에서 압축 강도 테스트 결과를 보면 수용성 고분자 수용액을 함유하는 시편 타일이 황토만의 시편 타일보다 압축 강도가 강하였으며, 특히 폴리비닐알콜 5% 수용액을 이용하여 제작된 시편 타일이 가장 강력한 것으로 측정되었다. 상기 표 1의 P-17은 P는 중간 검화형(검화도 85%이상)이며, 중합도 1700인 것을 뜻한다.In Table 1, the compressive strength test results showed that the specimen tile containing the aqueous aqueous solution of water had a higher compressive strength than that of the ocher-only specimen. In particular, the specimen tile manufactured using the 5% aqueous polyvinyl alcohol solution was determined to be the most powerful. It became. P-17 in Table 1 means that P is an intermediate saponification type (more than 85% saponification), and the degree of polymerization is 1700.

이어서 검화도와 중합도가 다른 폴리비닐알콜 5% 수용액을 이용하여 시편 타일을 하기 표 2에서와 같이 제조하였으며, 이에 대하여도 압축 강도를 측정하여 표 2에 나타냈다.Subsequently, a specimen tile was prepared as shown in Table 2 using a polyvinyl alcohol 5% aqueous solution having a different degree of saponification and polymerization degree, and the compressive strength thereof was also shown in Table 2 below.

상기 표 2에서 F는 완전 검화형(검화도 98%이상), P는 중간 검화형(검화도 85%이상)이며, 17과 24는 각각 중합도 1700과 2400을 뜻하며, 표 2의 결과를 보면 중합도와 검화도가 높을수록 인장강도 및 접착력이 증가하며 위의 압축강도 데이터에도 증명이 되었습니다. P-17보다는 P-24가, 중간 검화형 P보다 완전 검화형 F가 압축강도가 높은 것을 알 수 있습니다. 따라서 사용하기 가장 적절한 폴리비닐알콜은 완전 검화형에 중합도 1700인 폴리비닐알콜(F-17) 또는 중간 검화형에 중합도 2400인 폴리비닐알콜(P-24)임을 알 수 있다. 완전 검화형에 중합도 2400인 F-24 폴리비닐알콜은 이론적으로 가장 바람직할 수 있으나 F-24 폴리비닐알콜을 생산하는 곳이 없어 재료를 구하기가 어려운 문제점이 있다.In Table 2, F is a complete safflower type (more than 98% safflower), P is a medium safflower type (more than 85% safflower), 17 and 24 means a degree of polymerization of 1700 and 2400, respectively, The higher the degree of sagification and the higher the tensile strength and adhesion, the higher the compressive strength data. It can be seen that P-24 has higher compressive strength than P-17, and fully safty F than intermediate safing P. Therefore, it can be seen that the most suitable polyvinyl alcohol is polyvinyl alcohol (F-17) having a polymerization degree of 1700 in a fully saponified type or polyvinyl alcohol (P-24) having a polymerization degree of 2400 in a medium saponification type. F-24 polyvinyl alcohol having a degree of polymerization of 2400 for full saponification may be the most preferable in theory, but there is a problem in that it is difficult to obtain a material because there is no place for producing F-24 polyvinyl alcohol.

또한 폴리비닐알콜을 사용하여 수용액을 만드는 경우에는 수용성 고분자 이지만 물에 쉽게는 녹지않기 때문에, 물의 온도를 60℃~80℃ 정도의 더운 물에 폴리비닐알콜 파우더를 서서히 가하여 용해시키는 것이 바람직하다.In addition, in the case of making an aqueous solution using polyvinyl alcohol, it is a water-soluble polymer, but it is not easily dissolved in water, so it is preferable to dissolve the polyvinyl alcohol powder slowly in hot water of 60 ° C to 80 ° C.

상기 표 2에서 보는 바와 같이 Press 압력은 5t, 10t, 15t 으로 각각 측정하였으나 압축강도 물성에는 그다지 큰 차이는 보이지 않았습니다. 하지만, Press 압력 5t의 경우 황토타일 표면이 깨끗하지 못한 단점이 있습니다. 따라서 10t, 15t 정도의 압력이 필요하며, 단가 및 공정을 고려하여 10t정도의 압력이 적당하다고 볼 수 있겠습니다.As shown in Table 2 above, the press pressure was measured at 5t, 10t, and 15t, respectively, but there was no significant difference in compressive strength properties. However, the press pressure 5t has the disadvantage that the surface of the ocher tile is not clean. Therefore, a pressure of about 10t and 15t is required, and a pressure of about 10t may be considered considering the unit cost and process.

따라서 최종적으로 F-17 폴리비닐알콜 또는 P-24 폴리비닐알콜 5% 수용액을 이용하여 Press압력 10t으로 황토 타일을 제작하는 것이 가장 물성, 경제성, 생산성이 가장 좋다는 것을 알 수 있었습니다. Therefore, it was found that the best physical properties, economics and productivity were achieved by fabricating ocher tiles at 10t press pressure using 5% aqueous solution of F-17 polyvinyl alcohol or P-24 polyvinyl alcohol.

이상에서 살펴본 바와 같은 본 발명에 따르면 기존의 황토의 성질은 유지하면서 물에 강하고 강도가 높은 황토 타일을 2~10mm 두께로 얇게 제작할 수 있다.According to the present invention as described above, while maintaining the properties of the existing loess, it is possible to manufacture a strong ocher tile high in strength and high in thickness to 2 to 10 mm in thickness.
