Description

황토장식판넬 {A yellow-soil decoration panel}Ocher decorative panel {A yellow-soil decoration panel}

본발명은 황토를 이용하여 두께가 얇은 경량의 판넬을 얻게한 황토장식판넬에 관한 것으로,The present invention relates to an ocher decorative panel obtained by using a loess to obtain a thin and lightweight panel.

특히, 황토속에 들어있는 마사토 및 불순물을 제거하고 이를 미세하게 분쇄시킨 황토농축액에 펄프를 혼합교반하여 얻어진 황토혼합농축액을 3~10mm의 얇은 두께로 형성하고 이를 건조시켜 상면에는 맥반석, 게르마늄, 실리콘등으로 된 도포층을 도층시켜서 겉종이를 부착시키거나 직접겉종이를 부착시키고 바닥밑면에는 바닥지를 부착하여 경량이면서도 맥반석, 게르마늄, 실리콘등의 도포층에 의하여 인체에 유익한 원적외선의 발산으로 보온단열의 효과를 높게한 것으로,In particular, the ocher mixed concentrate obtained by mixing and stirring the pulp in the ocher concentrate finely ground and then removing the masato and impurities contained in the loess is formed into a thin thickness of 3 ~ 10mm and dried on the upper surface, such as elvan, germanium, silicon, etc. The outer layer is attached by coating the outer layer or attaching the outer sheet directly and attaching the bottom sheet to the bottom of the floor.The effect of thermal insulation by the emission of far-infrared rays, which is beneficial to the human body by the coating layer such as elvan, germanium and silicon, is light By raising the

제작된 황토장식판넬의 두께가 얇으므로 운반이나 시공 및 보수가 간단하고 본발명의 판넬을 이용하여 바닥이나 벽, 천정등을 장식할 수 있도록 다양한 색상을 창출하여 시각적 효과를 높힐 수 있는 보온단열효과와 원적외선방사효과를 갖는 내장제를 황토장식판넬로 할 수 있게 한 것이다.As the thickness of the manufactured ocher decorative panel is thin, it is easy to carry, construct and repair. Insulation effect that can enhance visual effect by creating various colors to decorate the floor, wall, ceiling, etc. using the panel of the present invention The interior decoration with far-infrared radiation effect can be made with ocher decorative panel.

종래의 황토판넬은 석고와 석면 그리고 종이로 제작되어 인체에 유해하며 기존황토제품은 황토벽을 황토몰탈, 황토핀이라고는 하나, 시공이 불편하고 무게가 중량이며 두께가 매우 두꺼워 사용이 불편하고 무게가 중량이며 두께가 매우 두꺼워 사용이 불편하고 시공이 용이치 않아 널리 보급되지 않고 특수한 경우에만 사용되고 있다.Conventional ocher panel is made of gypsum, asbestos and paper, which is harmful to human body. Existing ocher products are called ocher mortar and ocher pin, but it is inconvenient in construction, heavy in weight and very thick, making it inconvenient to use and Due to its weight and thickness, it is inconvenient to use and not easy to install, so it is not widely used and is used only in special cases.

이와같은 종래의 석고판넬은 온도 및 습도를 조절하지 못할 뿐만아니라 용도가 다양치 못하다.Such conventional gypsum panels not only control temperature and humidity, but also have various uses.

그리고 종래의 황토제품은 압착으로 만들어져 있기 때문에 제품이 정교하지 못하고 디자인이 다양하지 못하여 내장제로 사용하지 못하고 오직 황토라는 점에서 기초자제로만 사용되어지고 있는 실정이었다.In addition, the conventional ocher products are made by pressing, so the products are not sophisticated and the design is not varied, so they are not used as interior materials.

종래의 황토제품은 거의 모든 제품이 입착을 사용하여 만든제품으로써 황토벽돌 황토판넬이 있으나 모양이 정교하지 못하고 무게가 매우 무거우며 시공이 불편하고 생산이 용이치 못하다. 황토몰탈역시 시공이 매우 불편하고 공시기간이 길며 전열이 심하여 모양이 좋지 못하다.Conventional ocher products are made of almost all products using the adhering as the ocher brick ocher panel, but the shape is not elaborate and very heavy, the construction is inconvenient and not easy to produce. Ocher mortar is also very uncomfortable construction, long disclosure period and severe heat transfer, poor appearance.

시중의 황토벽지나 황토장판은 황토성분을 축출하여 기존장판에 첨가제작되였기 때문에 기존제품과 특별한 차이점을 발견할 수 없기 때문에 소비자에게 황토제품이라는 인식을 주지 못하고 있다.On the market, ocher wallpaper or ocher slate is not added to the old stool by removing the ocher constituents. Therefore, no special difference from the existing product can be found.

기존의 황토제품을 바닥, 벽, 천정에 시공하려면 일일이 황토몰탈을 발라야 하므로써 시공기간이 길고 시공방법이 번거로우며 균열이 발생하여 하자가 발생하며 시공단가가 높다.In order to install the existing ocher products on the floor, wall, and ceiling, it is necessary to apply ocher mortar every day, so the construction period is long, the construction method is cumbersome, cracks occur, and the construction cost is high.

현재 시중에 황토판넬이라고 나와있는 제품을 보면 두께가 매우 두껍고 중량이 무겁고 시공이 용이치 않으며 단지 황토벽돌의 제작방법에서 크게 탈피하지 못하고 벽돌제작방법과 동일한 압착으로 만들어져 있어 널리 보급되지 못하고 상품성이 떨어지는 문제점이 있었다.At present, the products that are called ocher panel are very thick, heavy, and not easy to install. They are not widely escaped from the process of making ocher bricks and made by the same pressing method as brick making method. There was a problem.

이러한 종래의 황토판넬들의 제반문제점을 해결하기 위하여 본발명의 목적은 두께가 얇으며 경량황토판넬을 얻게한 것으로 시공이 간단하고 보수가 용이하며 시공단가를 절감할 수 있도록 개발한 것이다.In order to solve the problems of the conventional ocher panel, the object of the present invention is to obtain a thin and lightweight ocher panel, which is simple to install, easy to repair, and to reduce construction cost.

경량황토판넬을 이용하여 바닥, 벽, 천정을 장식할 수 있도록 다양한 디자인과 색상을 창출하여 시각적효과를 높일 수 있도록 내장제로 개발하고 보온단열제로 사용할 수 있도록 개발한 것으로,It is developed to be used as a thermal insulation material and to develop various designs and colors to enhance the visual effect by decorating floors, walls and ceilings using lightweight ocher panels.

기존생활공간의 시멘트, 비닐, 철제속에서 우리조상의 생활문화였던 황토흙과 가까이 다가가며 맥반석, 게르마늄, 실리콘등을 첨가하여 인체에 더욱 유익한 판넬을 제공함에 본발명의 목적이 있는 것이다.The purpose of the present invention is to provide a more beneficial panel to the human body by adding ganban stone, germanium and silicon by approaching ocher soil, which was the life culture of our ancestors in the existing living space of cement, vinyl and iron.

상기한 목적을 달성하기 위하여 본발명의 황토장식판넬은 황토속에 들어 있는 불순물을 제거하고 미세하게 분쇄한 황토미립자와 분쇄펄프지를 혼합교반한 황토혼합액으로 두께 약3~10mm의 판넬을 형성하고 건조시켜 상,하면에 직접 겉지를 부착사용하거나, 맥반석, 게르마늄, 실리콘 분말입자를 도포한 위에 겉지를 상면에 바닥지를 밑면에 각각 부착시켜 본발명의 황토장식판넬을 제공받게한 것이다.In order to achieve the above object, the ocher decorative panel of the present invention removes impurities contained in the ocher, forms a panel having a thickness of about 3 to 10 mm with an ocher mixture mixed with finely pulverized ocher particles and pulverized pulp paper, and dried. The upper and lower surfaces are directly attached or used, or the upper surface and the bottom surface are attached to the bottom surface, respectively, on which elvan, germanium, and silicon powder particles are applied, thereby providing the ocher decorative panel of the present invention.

본발명의 구성을 도1과 도2에 의해 상세히 설명하기로 한다.The configuration of the present invention will be described in detail with reference to Figs.

황토속에 있는 마사토와 불순물을 제거한 순수황토와 펄프를 물에 풀어준 펄프(5) 농축물을 함께 혼합교반하여서 교질화된 황토혼합층(3)을 3~10mm의 얇은 두께로 성형하고 건조과정중 상,하면에 겉지(1)와 바닥지(4)를 직접 부착시키거나,상면에는 맥반석, 게르마늄, 실리콘등의 도포층(2)을 도포하여 그 상면에는 겉지(1)를 부착하고 밑면에는 바닥지(4)를 부착성형하여 본온단열기능과 원적외선 방사효과를 갖는 황토장식판넬(A)을 제공받는 것이다.Mixing and stirring masato in the ocher, pure ocher with impurities removed and pulp (5) concentrate in which the pulp was released in water was formed, and the gelatinized ocher mixed layer (3) was formed into a thin layer of 3 to 10 mm in thickness during the drying process. The bottom surface 1 and the bottom surface 4 are directly attached to the lower surface, or the upper surface 1 is coated with a coating layer 2 such as ganbanite, germanium and silicon, and the upper surface 1 is attached to the upper surface, and the bottom surface is attached to the bottom surface. By attaching and molding (4), it is provided with ocher decorative panel (A) which has an insulator function and far-infrared radiation effect.

이때 본발명에 사용되는 황토는 마사토와 불순물을 제거하고 순수한 황토만 축출하여 농축시킨것이며, 여기에 혼합되는 펄프(5) 농축물은 폐지를 사용하여 믹서기등에서 황토농축액과 함께 미세하게 갈아주는 것이다.At this time, the ocher used in the present invention is to remove masato and impurities, and concentrate only by removing the pure ocher, and the pulp (5) concentrate mixed therein is finely ground together with the ocher concentrate in a blender using waste paper.

이와같이하여 황토농축물과 펄프농축물이 함께 혼합교반되어 교질화하므로 서로의 결속력이 높아져 점도가 높은 관계로 서로 잘 엉켜지게되어 얇은 두께(약3~10mm이내)의 판상으로 성형하여도 되는 것이다.In this way, the ocher concentrate and the pulp concentrate are mixed and agitated together so that the cohesion of each other increases and the viscosity is high so that they are entangled with each other and formed into thin plates (within about 3 to 10 mm).

이와같은 상태의 판상으로 성형하여 건조시키는 과정중 인체에 유익하며 보온단열효과와 원적외선방사기능을 갖는 맥반석, 게르마늄, 실리콘등의 재료를 미분쇄한 분말을 판상의 황토혼합층(3) 상면에 일정두께로 도포하여 도포층(2)을 갖게한 상태에서 종이로된 겉지(1)를 도포층의 상면에 판상의 밑면에는 바닥지(4)를 각각 부착시켜 황토장식판넬(A)을 형성하여 주므로서 상,하면에 부착된 겉지(1)와 바닥지(4)에 의하여 판넬이 부서지거나 파손되는 것을 방지할 수 있고 겉지와 바닥지의 색상 또는 표면처리방법에 의하여 매끄럽고 다양한 무늬등을 갖는 판넬을 얻게되므로 다양한 두께와 무늬모양 및 색채를 갖는 제품을 제공할 수 있어 상품가치성을 높혀주게한 것이다.It is beneficial to the human body during the process of forming and drying in the shape of plate in such a state, and the powder which is pulverized with materials such as ganbanite, germanium, and silicon having heat insulating effect and far infrared radiation function on the upper surface of the plate-shaped ocher mixed layer (3) In the state that the coating layer (2) is applied by applying a paper to the upper surface of the coating layer on the bottom surface of the plate (4) is attached to each of the bottom paper (4) to form the ocher decorative panel (A) Panels can be prevented from being broken or damaged by the upper and lower surfaces 1 and 4 attached to the upper and lower surfaces, and a panel having smooth and various patterns can be obtained by the color or surface treatment method of the outer and the ground. It is possible to provide products with various thicknesses, patterns, and colors, thereby enhancing product value.

이와같은 상태로 제조된 본발명의 황토장식판넬은 시멘트 및 철의 사용 및 비닐사용으로 우리인체에 나쁜영향을 주는 요소를 생흙인 경량황토판넬을 사용하여 차단하였으며,The ocher decorative panel of the present invention manufactured in such a state blocked elements that adversely affect the human body by using cement and iron and vinyl using lightweight ocher panel, which is raw soil.

기존 석고보드나 판넬은 인체에 매우 해로우므로 세계적으로 사용이 점차금지되고 있으므로 그 대체품으로 유용한 것이다.Existing gypsum board or panel is very harmful to the human body, so it is useful as a substitute because it is increasingly prohibited worldwide.

그리고, 황토경량장식판넬은 디자인 및 색상이 다양하고 내장제로 사용이 가능하며 보온단열 및 습도를 조절하며 시공이 용이하고 경비를 절감할 수 있어 아파트 및 일반주택 내장제 및 기초자재로 사용이 가능하다.In addition, the ocher lightweight decorative panel has various designs and colors, can be used as interior materials, and can be used as interior materials and basic materials for apartments and general houses because it can be easily installed and can reduce costs by controlling thermal insulation and humidity.

생황토는 농축시켜 제작하였기 때문에 가볍고 얇은판으로 제작되었으므로 소비자의 눈으로 확인할 수 있어 구매욕구를 충족시킬 수 있을 뿐만아니라 소량다품종 생산이 가능하다.Since the raw ocher is concentrated and manufactured, it is made of light and thin plates so that it can be confirmed by the eyes of consumers, and it is possible to satisfy the purchase needs and to produce small quantities of various varieties.

재료구입이 용이하고 재활용품을 이용할 수 있으며 유지보수가 간편하고 자연 친화적 제품이기 때문에 폐기물이 유발되지 않는 매우 획기적이고 활용성이 좋은 제품이다.It is very innovative and easy to use because it is easy to purchase materials, use recycled materials, easy to maintain and nature-friendly.
