Description

건축에 사용되는 판넬에 있어서 내화기능 보강방법 { The method of reinforcing fireproof function in panel by using building }The method of reinforcing fireproof function in panel by using building}

본 발명은 건축에 사용되는 판넬에 있어서 내화기능 보강방법에 관한 것이며 보다 구체적으로는 판넬의 제조공정에서 그라스울 상부에 규소 또는 규산나트륨을 주재로 한 내화층을 구비하여 판넬의 내화기능을 보강한 것이다.The present invention relates to a method for reinforcing a fireproof function in a panel used in a building, and more particularly, to reinforce a fireproof function of a panel by having a fireproof layer mainly composed of silicon or sodium silicate on an upper part of a glass wool in a panel manufacturing process. .

오늘날 건축공법의 발달과 변화로 인하여 건축물의 벽체, 지붕, 실내구획을 신속하게 하기 위하여 철판재내에 그라스울을 구비하는 판넬이 널리 이용되고 있다.Today, due to the development and change of construction method, panel with glass wool in steel plate is widely used to speed up the wall, roof and interior of building.

이에 사용되고 있는 종래의 판넬은 철판재, 접착제, 그라스울, 접착제, 철판재를 차례로 적층하여 압착을 제조가 이루어지고 있고, 외피인 철판재의 경우에는 융점이 1,300℃이고 그라스울은 융점이 350℃ 이어서 상온에서의 사용에는 별다른 문제가 없으나 300℃ 이상에서는 내화기능이 떨어져 고온에서의 내화기능을 갖는 판넬이 절실히 요구되고 있고, 이에 따라 고온에서 내화기능을 갖는 판넬제조공법에 많은 연구가 이루어지고 있으며 내화기능이 보강되는 판넬로는 2000년 특허출원제75457호와 같이 통상 판넬에 석고 보드층을 구성하여 석고보드에 의한 내화기능을 보강할 수 있도록 하는 수단등이 발명된 바 있으나 이는 석고보드로 인한 판넬의 중량이 증가되는 폐단이 있고, 또 내화기능이 높은 흑연등으로 내화층을 구성하게 되면 제조원가가 상승되어 경제성이 떨어지는 폐단이 있다.Conventional panels used for this are manufactured by pressing laminated steel plates, adhesives, glass wool, adhesives, and iron plates in sequence, and in the case of the outer steel sheet, melting point is 1,300 ° C and glass wool is 350 ° C at room temperature. There is no problem in the use of, but the fireproof function is deteriorated above 300 ℃, so a panel having a fireproof function at a high temperature is desperately required. Accordingly, a lot of researches have been made on a panel manufacturing method having a fireproof function at a high temperature. As a panel to be reinforced, a means for reinforcing a fireproof function by a gypsum board has been invented by forming a gypsum board layer on a panel as in Patent Application No. 75457 in 2000, but this is the weight of the panel due to gypsum board. If the fire resistant layer is made of graphite with high fire resistance and high fire resistance, the manufacturing cost is increased. There are two poor economic evils.

이에 본 발명은 통상 판넬을 제조하면서 그라스울의 상부에 규소 또는 규산나트륨은 주재로 한 분말 또는 액을 도포시켜 그라스울과의 혼용층을 구성하여 판넬의 제조를 간편히 하고, 경량화하면서 일정온도에 이르면 발포되어 내화층이 형성되면서 내화기능이 보강되도록 하는 판넬의 내화기능 보강방법을 제공함에 목적이 있다.Therefore, the present invention is to prepare a panel by mixing a powder or a liquid mainly made of silicon or sodium silicate on the top of the glass wool while manufacturing the panel to form a mixed layer with the glass wool to simplify the production of the panel, and to be lightweight and foamed when it reaches a certain temperature It is an object of the present invention to provide a method of reinforcing a fireproof function of a panel to which a fireproof function is reinforced while a fireproof layer is formed.

[제3공정](그라스울 공급공정)[3rd process] (Glass wool supply process)

제2공정의 접착제(2) 위에 롤(ROll)상의 그라스울(3)을 구성한다.The glass wool 3 on a roll ROll is comprised on the adhesive agent 2 of a 2nd process.

동 그라스울은 판넬의 규격에 따라 두께를 선택하고, 밀도는 대체적으로 48Kg/㎥ 이상이고, 수지부착율은 12%이상, 열밀도율은 70℃에서 0.037㎉/mh℃이하를 기준으로 하나 판넬의 용도와 규격에 따라 변화될 수 있다.The copper wool is selected according to the panel size. The density is generally 48Kg / ㎥ or more, the resin adhesion rate is 12% or more, and the thermal density rate is 7037 ℃ or less than 0.037㎉ / mh ℃. It may vary depending on the application and specification.

[제4공정](규사 또는 규산나트륨 도포공정)[Step 4] (Silicite or Sodium Silicate Coating Process)

제3공정의 그라스울(3)에 규소(Si)를 주재로 한 분말상태 또는 액상의 규산나트륨(SiNa₂O₃) 용액의 내화소재를 도포하여 그라스울(3)에 유입되어 그라스울과 규소 또는 규산나트륨이 혼용되는 내화층(10)을 구성한다.The refractory material of powder or liquid sodium silicate (SiNa₂O₃) solution mainly containing silicon (Si) is applied to the glass wool (3) of the third step, and the glass wool (3) flows into the glass wool (3) to mix glass wool with silicon or sodium silicate. The fire resistant layer 10 is comprised.

이 때 규소분말의 경우에는 그라스울에 붙게되면서 다공부에 유입충진되어 내재되고, 규산나트륨 용액의 경우에는 그라스울 소재를 일정두께 코팅한 상태로 건조되어 내화층(10)을 구성하게 된다.At this time, in the case of the silicon powder is adhered to the glass wool and filled in the porous part, and in the case of sodium silicate solution is dried in a state in which the glass wool material is coated with a certain thickness to form a fireproof layer (10).

[제5공정](접착제 도포공정)[Fifth step] (adhesive application step)

제4공정의 내화층(10) 표면에 발포성 수지접착제를 도포시켜 접착제(4)을 조성한다.The adhesive agent 4 is formed by apply | coating a foamable resin adhesive to the surface of the fireproof layer 10 of a 4th process.

[제6공정](철판재 공급공정)[Step 6] (Steel Sheet Supply Process)

제5공정의 접착제(4)위에 제1공정과 같이 절곡되는 철판재(5)를 구성한다.On the adhesive agent 4 of a 5th process, the iron plate material 5 bend | folded like a 1st process is comprised.

[제7공정](접합공정 및 제품화 공정)[7th process] (bonding process and commercialization process)

제1공정 내지 제6공정을 경료하여 적층된 소재를 압착로울러에 통과하면 판넬이 제조되고 이를 규격으로 절단하여 제품화한다.When the laminated materials are passed through the pressing roller after passing through the first to sixth processes, the panel is manufactured and cut into a standard to be commercialized.

이와 같이 제조된 판넬은 규소 또는 규산나트륨의 내화소재가 그라스울(3)에 일정두께 도포시켜 내화기능이 보강되는 내화층(10)을 구비하게 되므로 내화기능이 보강되고, 그 작업공정이 간단하여 제조가 용이하게 된다.The panel manufactured as described above is provided with a fireproof layer 10 in which a refractory material of silicon or sodium silicate is applied to the glass wool 3 to a certain thickness, thereby reinforcing the fireproof function. Becomes easy.

또한 판넬은 경량상태를 유지하게 되므로서 사용이 편리하게 되며 동 판넬에 도포되는 규소 또는 규산나트륨을 주재로 하는 분말 또는 액상의 소재는 가격이 저렴하고 700℃~800℃의 고온에 이르게 되면 규소 또는 규산나트륨은 발포되면서 그내에 그라스울이 내재되어 발포내화층이 구성되고 동 발포내화층은 단열기능을 갖게 되면서 1,200℃에 이르기까지 변화없이 내화기능을 갖게 된다.In addition, the panel is light and easy to use, and the powder or liquid material mainly made of silicon or sodium silicate applied to the panel is inexpensive and reaches a high temperature of 700 ° C to 800 ° C. As the sodium silicate is foamed, glass wool is embedded in the foamed fireproof layer, and the foamed fireproof layer has a heat insulation function, and has a fireproof function without change up to 1,200 ° C.

또 본 발명의 제4공정에서 규사 또는 규산나트륨의 도포량의 설정은 판넬의 사용용도와 요구되는 내화온도에 따라 그라스울(3)에 도포량을 조절할 수 있게 된다.In addition, in the fourth step of the present invention, the coating amount of silica sand or sodium silicate can be adjusted to the coating amount of the glass wool 3 according to the usage of the panel and the required refractory temperature.

일예로 내화온도가 높으면 그라스울(3)에 규사 또는 규산나트륨의 단위면적당 도포량을 늘이게 되면 고온에서 규소가 발포되어 내화층이 두꺼워지게 되고 도포량을 줄이면 고온에서 규소 발포시 내화층이 엷어지게 된다.For example, if the refractory temperature is high, increasing the coating amount per unit area of silica sand or sodium silicate on the glass wool (3) increases the foaming of the silicon at high temperatures, resulting in a thickening of the refractory layer.

또 이와 같은 본 발명은 앞에서와 같이 규소 또는 규산나트륨을 그라스울에 도포상태로 제조하여 제품화 할 수 있고, 그라스울소재에 규소 또는 규산나트륨을 도포시켜 이를 700℃~800℃의 소성로를 통과시켜 발포성형시키게 되면 내화용 보드가 구성되므로 이를 그라스울과 함께 적층시켜 판넬을 제조할 수도 있다.In addition, the present invention can be produced by producing a silicon or sodium silicate in a glass wool coating state as described above, by applying the silicon or sodium silicate to glass wool material to pass through a firing furnace of 700 ℃ ~ 800 ℃ to foam molding If the refractory board is configured, it can be laminated with glass wool to manufacture a panel.

이상과 같은 본 발명은 판넬의 제조공정에 그라스울 위에 규소 또는 규산나트륨을 주재로 한 분말 또는 액을 도포시켜 판넬을 제조하므로서 판넬의 제조공정에 변화 없이 제조할 수 있게 되고 제조된 판넬은 경량화되면서 내화기능을 갖는 내화층이 구비되므로서 내화기능이 요구되는 각종 건축물의 판넬로 널리 이용할 수 있고, 규소 또는 규산나트륨은 저가이어서 경제성이 있고 널리 실용화할 수 있는 유용한 발명이다.The present invention as described above can be manufactured without change in the manufacturing process of the panel by applying a powder or a liquid mainly made of silicon or sodium silicate on the glass wool in the manufacturing process of the panel and the manufactured panel is lightweight and fireproof Since a fireproof layer having a function is provided, it can be widely used as a panel of various buildings requiring a fireproof function, and silicon or sodium silicate is a useful invention that can be economically and widely used because it is inexpensive.
