본 발명은 친환경 샌드위치판넬 제조방법에 관한 것으로서, 좀더 상세하게 설명하면 샌드위치 판넬에서 금속판 사이에 넣는 단열부재를 내화성이 높고 유독가스가 발생하지 않는 천연재료를 삽입하도록 한 친환경 샌드위치 경량 건축판넬 제조방법에 관한 것이다.The present invention relates to a method for manufacturing an environmentally friendly sandwich panel, and more specifically, to an environmentally friendly sandwich lightweight building panel manufacturing method for inserting a natural insulating material having high fire resistance and no toxic gas to be inserted between metal plates in the sandwich panel. It is about.

일반적으로 샌드위치 판넬이라고 하면 금속판 사이에 단열부재(심재)를 넣어 판넬형태로 제작하는 것으로 금속판은 보통 0.5미리 아연도금강판을 많이 사용하며 최근에는 단가 문제로 인하여 점점 얇은 기판을 사용하는 추세이다.In general, a sandwich panel is manufactured in the form of a panel by inserting an insulation member (core material) between the metal plates. The metal plate is generally used 0.5 mm galvanized steel sheet, and recently, due to the unit cost problem, the trend is to use thinner substrates.

이때 단열재는 스치로폴폼, 그래스울, 미네랄울 등의 여러가지 재료를 사용하나 가장 많이 사용하는 것은 저렴한 스치로폴폼을 이용한 경량 판넬이다.At this time, the insulating material uses various materials such as styrofoam foam, glass wool, and mineral wool, but the most commonly used is a lightweight panel using inexpensive styrofoam foam.

하지만 스치로폴폼을 실제로 사용하는 판넬은 가볍고 가격이 저렴하나, 화재가 발생하는 경우 철판 사이에서 불이 확산 되기 때문에 화재를 진화하기 어려워 건물이 전소될 때까지 대책이 없을 뿐만 아니라, 대량의 유독가스가 발생하여 화재시 주변으로 화재가 확산되는 것을 방지하기 위한 소극적인 진화를 할 수밖에 없는 너무나 위험하고 단점이 많은 자재이다.However, the panel that actually uses Styrofoam foam is light and inexpensive.However, if a fire breaks out, the fire spreads between the steel plates, so it is difficult to extinguish the fire, and there is no countermeasure until the building is burned down. It is a material that is too dangerous and has many disadvantages that have to be passively extinguished to prevent the fire from spreading to the surroundings in case of fire.

또한 유리섬유를 이용하여 제조하는 그라스울 판넬 및 석면을 이용한 미네랄 울 판넬은 내화성능은 우수하나 가격이 고가이며 특히 유리섬유는 무척 날카롭기에 미세한 분진 형태로 피부에 박히거나 호흡기에 침투하면 치명적인 인체의 손상을 가져올 우려가 있는 문제점이 있다.In addition, glass wool panels manufactured using glass fibers and mineral wool panels using asbestos are excellent in fire resistance, but are expensive. Especially, glass fibers are very sharp and fine dust, which is very fine in the form of fine dust and can cause fatal effects on human body. There is a problem that may cause damage.

한편 왕겨나 볏짚을 이용한 단열재 조성물이 국내특허 등록 제 0186715호로 알려졌으나, 이 경우 바인더로 합성수지를 사용하는 것이어서 화재에 약하고, 화재시 연기 등이 발생하는 문제점이 있다.On the other hand, the insulation composition using rice husk or rice straw is known as Korean Patent Registration No. 0186715, but in this case it is a synthetic resin as a binder is weak to fire, there is a problem that smoke occurs in the fire.

또한 왕겨 또는 볏짚과 진주석과 규조토 및 수용성 바인더를 일정비율로 혼합하여 프레스 성형한 왕겨 또는 볏짚을 이용한 보온 단열재가 국내공개특허 제 2002-0035814호로 알려져 있는바, 이는 부피 비율로 볏짚이 45~48%, 진주석이 40~38%, 규조토가 4.5~5.5%, 수용성 바인더가 10.5~8.5%로 구성된 것이나, 보온 단열재로서의 기능을 수행 가능토록 개발된 것이어서, 볏짚 대비 진주석과 규조토의 첨가량이 상대적으로 많은 것이어서 중량이 많이 나가고, 진주석과 규조토의 첨가 량이 많아 원가가 상승하는 요인이 되어 경량 판넬에는 적합하지 않은 문제점이 있다.In addition, heat insulation using chaff or rice straw, which was formed by mixing rice husk or rice straw, mother-of-pearl, diatomaceous earth, and water-soluble binder at a predetermined ratio, is known as Korean Patent Publication No. 2002-0035814, which is 45 to 48% by volume. It is composed of 40-38% of pearlite, 4.5-5.5% of diatomaceous earth, and 10.5-8.5% of water-soluble binder, but it was developed to perform the function as a thermal insulation material, and the amount of pearlite and diatomaceous earth is relatively higher than that of rice straw. A lot of weight, the addition of pearlite and diatomaceous earth is a factor that increases the cost, there is a problem that is not suitable for lightweight panels.

본 발명은 상기와 같은 문제점을 해결하기 위하여 개발된 것으로서, 그 목적은 내화성이 있는 천연소재의 경량 단열부재(건초보드)를 이용한 샌드위치 판넬을 제공하는데 있다.The present invention was developed to solve the above problems, an object of the present invention is to provide a sandwich panel using a lightweight insulating member (hay board) of a natural material with fire resistance.

또한 본 발명의 다른 목적은 건초를 화산재를 포함하는 바인더로 결합하여 성형함으로써, 화산재에서 발생하는 원적외선과 음이온에 의하여 항균성을 갖는 친환경 샌드위치 경량 건축판넬 제조방법을 제공하는데 있다.In addition, another object of the present invention is to provide a method for manufacturing an environmentally friendly sandwich lightweight building panel having antibacterial by far infrared rays and negative ions generated from the ash by combining hay with a binder containing a volcanic ash.

이를 위하여 본원발명은 건초와 화산재를 주성분으로 하는 바인더를 혼합하여 일정 두께로 건조하여 보드 크기로 절단한 후 샌드위치형 경량 판넬의 내장재로 내장시킨다.To this end, the present invention is mixed with a binder containing hay and volcanic ash as a main component, dried to a predetermined thickness, cut into a board size and then embedded as a sandwich-type lightweight panel interior material.

즉, 본 발명의 제 1 예는 테두리는 금속판 하우징이, 내부는 한쌍의 석고판과, 각 석고판 사이에 안치되는 스치로폴폼을 금속판 하우징 내에 내장시키고, 하우징의 폭방향 양단에는 요철이 있어 상호 끼움 결합되는 경량판넬에 있어서,That is, according to the first example of the present invention, a metal plate housing has a rim, a pair of gypsum plates inside, and a styrofoam foam placed between the gypsum plates are embedded in the metal plate housing, and both ends of the housing have unevenness in the width direction. In the combined lightweight panel,

본 발명에 사용하는 화산재는 알루미늄, 칼슘, 산화철, 마그네슘 등의 미네랄 성분을 포함하고 있으며, 산화물형태로는 SiO2, Al2O3, Fe2O3 형태로 존재한다.화산재의 성분으로는 SiO2 65~75W%, Al2O3 16~18Wt%, Fe2O3 1~2Wt%, CaO 1~2Wt%, MgO 0.1~0.5Wt%, K2O1~2Wt%, Na2O 1~2Wt%, 기타 5Wt%로 알려져 있으나, 지역에 따라 성분 조성비가 달라지나, 핵심 조성 성분은 대체로 유사하다.Volcanic ash used in the present invention contains minerals such as aluminum, calcium, iron oxide, magnesium, etc., and is present in oxide form in the form of SiO 2, Al 2 O 3 , Fe 2 O 3 . 2 65 ~ 75W%, Al 2 O 3 16 ~ 18Wt%, Fe 2 O 3 1 ~ 2Wt%, CaO 1 ~ 2Wt%, MgO 0.1 ~ 0.5Wt%, K 2 O1 ~ 2Wt%, Na 2 O 1 ~ 2Wt %, Other 5Wt%, but the composition ratio varies depending on the region, but the core composition is generally similar.

이러한 화산재는 FT-IR 스펙트로미터를 이용하여 측정하면 원적외선 방사율(5~20마이크로미터)은 섭씨 40도에서 약 92.5%이고, 방사에너지는 약 3.72곱하기102 W/m2마이크로미터,섭씨40도로 알려져 있는 것을 본 발명의 재료로 이용하였다.The volcanic ash is measured using the FT-IR spectrometer, and the far-infrared emissivity (5-20 micrometers) is about 92.5% at 40 degrees Celsius, and the radiation energy is about 3.72 times 10 2 W / m 2 micrometers and 40 degrees Celsius. Known one was used as the material of the present invention.

본 발명에서 사용하는 화산재는 분쇄기에서 분쇄하여 평균입도 25~42메시로 분쇄한 것이 바람직한바, 이는 25메시 이하로 되면 결착력이 저하되고, 42메시를 넘으면, 건초에 대한 화산재의 첨가량이 많아져, 경량성 판넬에 부적합하다. The volcanic ash used in the present invention is preferably crushed in a crusher and crushed to an average particle size of 25 to 42 mesh, which is less than 25 mesh, the binding force is lowered, and if it exceeds 42 mesh, the amount of ash added to hay increases. Not suitable for lightweight panels.

본 발명에 사용하는 건초는 1년생 건초가 좋고, 특히 비목과 식물의 줄기 즉, 볏짚, 억새풀, 갈대, 보릿대, 옥수수대, 수숫대 등이 사용 가능하며, 건초들의 사용에 있어서는 단독 또는 적당량 씩 혼합 즉, 일 예로써 볏짚과 갈대를 혼합하거나, 또는 볏짚에 억새풀과 갈대를 첨가 사용할 수도 있다. 이러한 1년생 건초의 줄기는 마디가 있고 원통형으로 이루어져 속이 비어있기에 단열부재의 무게를 줄일 수 있을 뿐만 아니라 구조적으로 밀집된 구성이어서 부수적으로 단열 및 방음의 효 과도 얻을 수 있게 된다. 특히 가장 쉽게 구할 수 있는 것은 추수 후의 볏짚으로 다른 단열부재와 비교하여 저가이고 다량으로 얻을 수 있는 장점을 가지고 있음도 특징이다. Hay used in the present invention is a year-old hay is good, in particular, the stems of trees and plants, that is, rice straw, pampas grass, reeds, barley, cornstalks, etc. can be used, in the use of hay mixed alone or an appropriate amount, that is, For example, rice straw and reed may be mixed, or straw grass and reed may be added to rice straw. Since the stem of the annual hay has a node and a hollow shape, it can not only reduce the weight of the insulation member but also have a structurally dense structure so that the effect of insulation and sound insulation can be obtained. In particular, the most readily available is straw after harvesting, which has the advantage of being inexpensive and obtained in large quantities compared to other insulation materials.

본 발명에 사용하는 바인더는 25~42메시의 화산재 분말 60~70중량%, 수용성본드 30~40중량% 비율로 혼합하는 것이 좋은바, 이는 목재 등의 접착제로 사용되는 수용성 목공본드(Polyvinyl acetate)인 수용성본드(예를들어 상표명;오공본드)가 30중량%보다 적게 혼합되면 접착력이 낮아져 내구성이 떨어지고, 40중량%를 초과하면 건조시간(두께에 따라 온도에 따라 다르나 건조시간은 30미리 두께의 건초보드인 경우 섭씨 50내지 80도 에서 약 2~3시간 이 걸렸다)이 길어져 작업성이 떨어진다.The binder used in the present invention is preferably mixed at a ratio of 60 to 70% by weight of the ash powder of 25 to 42 mesh and 30 to 40% by weight of the water-soluble bond, which is a water-soluble woodworking bond (Polyvinyl acetate) used as an adhesive such as wood. When water-soluble phosphorus (e.g., trade name; pore bond) is mixed at less than 30% by weight, the adhesive strength is lowered and durability is reduced.When it is more than 40% by weight, the drying time (depending on the temperature depending on the thickness, but the drying time is 30mm thick In the case of hay boards, it took about 2-3 hours at 50 to 80 degrees Celsius).

이에 본 발명의 구성을 첨부된 도면에 의하여 당업자가 용이하게 이해하고 재현할 수 있도록 상세하게 설명하면 다음과 같다.Accordingly, the configuration of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce.

도 1 은 본 발명의 제 2 예에 따른 분해 사시도로써, 중앙에 건초보드(1)가 형성되고 테두리는 금속판(2)이 하우징을 이루도록 감싸는 구성을 이루며, 건초보드(1)는 일정 크기(바람직하기는 1~10센티미터)로 절단된 1년생 건초(11)와, 바인더(12)를 혼합하여 일정 두께의 보드를 이루도록 성형한다.1 is an exploded perspective view according to a second example of the present invention, the hay board (1) is formed in the center and the edge forms a configuration surrounding the metal plate (2) to form a housing, hay board (1) is a certain size (preferably In the following, 1 year hay (11) cut into 1 to 10 centimeters) and the binder 12 are mixed to form a board having a predetermined thickness.

이러한 상기 건초보드(1)는 종래 스치로폴폼으로 이루어지는 단열부재와 비교하여 발화온도가 낮고, 연소에 걸리는 시간이 느리며, 간단한 화재시에도 단열부재(종래의 스티로폴폼)가 용융되어 단열부재가 위치했던 자리가 공동으로 되어 내구성에 치명적인 영향을 미치는 것을 방지할 수 있다.The hay board 1 has a lower ignition temperature, a slower time to burn, and a heat insulation member (conventional styrofoam foam) is melted even in a simple fire compared to a heat insulation member made of conventional styrofoam foam. The seats can be cavityed to prevent a critical impact on durability.

Forming process (third process), drying process for drying the formed heat insulating member, and assembling process for attaching metal plates to both sides of the dried heat insulating member (indicated as the fourth process in combination with the above-mentioned assembly process and drying process). A series of processes are made in succession. First, the process of making the binding additives (first process) is performed. In FIG. 2, this is omitted.

이때 상기 건조과정은 직접 가열식 또는 열풍에 의한 건조를 하는 것을 에시할 수 있고, 성형과정에서는 직접 가열로 최종 건조되도록 할 수도 있다.In this case, the drying process may be performed by drying by direct heating or hot air, and may be finally dried by direct heating in the forming process.

상기표에서 강도는 가로세로 30센티의 건초보드 시편 10개를 1미터 높이에서 자유낙하시켰을 때 절단되는 개수를 측정한 것으로, 실시예 1 내지 3은 대체로 건조시간이 2시간대로 균일하고, 부서지는 것이 없어 건축보드로서 안전함을 확인할 수 있었고, 비교예 1 은 3개가 부서져 건축보드로서 사용 불가능함을 알 수 있고, 비교예 2 는 강도는 이상이 없으나 건조시간이 많이 걸려 생산성이 저하되는 문제점이 있음을 알 수 있다.In the above table, the strength is measured by free-falling 10 hayboard specimens having a width of 30 centimeters at a height of 1 meter. Examples 1 to 3 generally have a uniform drying time of 2 hours. It can be confirmed that there is no safety as a building board, Comparative Example 1 can be seen that it is impossible to use as a building board broken three, Comparative Example 2 has a problem that the productivity is reduced due to the high drying time is not abnormal It can be seen.

본 발명은 또한 상기 실시예 1 을 통하여 수득한 경량판넬을 사용하여 한국 건자재시험연구서를 통한 항균시험을 실시하였는바, 사용한 균은 대장균(Escherichia coli ATCC 25922)를 사용하고 시험방법(KICM-FIR-1002)으로 시험하였는바, 세균 감소율이 0,5% 감소하는 것을 확인할 수 있었다. 이는 균의 생성이 용이한 자연생건초를 사용하지만 화산재분말을 통한 원적외선과 음이온의 발산으로 세균수가 감소하는 것으로 판단된다.The present invention also carried out the antibacterial test through the Korea Construction Materials Test Report using the lightweight panel obtained through Example 1, the bacterium used was E. coli (Escherichia coli ATCC 25922) and the test method (KICM-FIR- 1002), it was confirmed that the bacterial reduction rate is reduced by 0,5%. It uses natural hay that is easy to produce bacteria, but the number of bacteria decreases due to the emission of far infrared rays and anions through volcanic ash powder.

상술한 바와 같이 본 발명은 화산재와 수용성 본드를 혼합한 것을 바인더로 사용하여 건초와 섞어 샌드위치판넬의 단열부재를 제조함으로써 환경오염을 줄이고 자원의 낭비를 방지하는 효과가 있다.As described above, the present invention has an effect of reducing environmental pollution and preventing waste of resources by manufacturing a heat insulating member of a sandwich panel by mixing with hay using a mixture of volcanic ash and a water-soluble bond as a binder.

또한 가장 보편적인 스치로폴을 이용한 판넬 보다 대화능력이 우수하여 화재시 재산과 인명의 손실을 억제하는 효과가 있다.In addition, the ability to communicate better than panels using the most common Schiropol has the effect of suppressing the loss of property and life in the event of fire.

또한 건초를 화산재와 수용성 본드를 결합한 바인더로 건초를 적정량 혼합하여 건조시켰기에 형태를 유지할 정도의 강도를 갖추어 경량 판넬로서의 성능을 유지할 수 있고,In addition, hay is mixed with an appropriate amount of hay with a binder that combines volcanic ash and a water-soluble bond, so that it has strength enough to maintain its shape, thereby maintaining its performance as a lightweight panel.

화산재를 통한 원적외선 등의 발산으로 항균성을 확보하여 건초를 사용한 경량판넬 이라 할지라도 경량 웰빙 건축 자재로 사용 가능토록 한다.The anti-microbial property is secured by the emission of far infrared rays through volcanic ash so that even light panels made of hay can be used as lightweight well-being building materials.
