Description
본 고안은 우레탄 판넬에 관한 것으로, 보다 상세하게는 우레탄 판넬 내부에 우레탄의 발열을 차단할 수 있는 단열보드, 바람직하게는 난연성 E.P.S를 내장하여, 우레탄 판넬의 최종 제조공정인 우레탄 숙성공정에서 우레탄의 발열로 인해 표면판재가 변형되는 현상을 방지할 수 있는 우레탄 판넬에 관한 것이다.The present invention relates to a urethane panel, and more specifically, a heat-insulating board that can block the heating of the urethane inside the urethane panel, preferably a flame retardant EPS is embedded, the heat generation of the urethane in the urethane maturing process, which is the final manufacturing process of the urethane panel It relates to a urethane panel that can prevent the phenomenon that the surface plate deformation.
도1은 건축물의 내외장재로서 일반적으로 사용되는 샌드위치 판넬의 단면도로서, 이를 참고하면 샌드위치 판넬은 상하부 표면판재(11, 12) 사이로 방음과 단열을 위한 중간단열재(13)가 구비되어 구성된다. 또한, 상기 상하부 표면판재(11, 12)의 양측은 서로 연결하여 설치할 수 있도록 굴곡진 결합부(11-1, 11-2, 12-1, 12-2)로 구성되어 있으며, 결합부는 테이프(P)로 마감되어 있다.1 is a cross-sectional view of a sandwich panel generally used as interior and exterior materials of a building, referring to the sandwich panel is provided with an intermediate insulation material 13 for sound insulation and insulation between the upper and lower surface panels 11 and 12. In addition, both sides of the upper and lower surface plate material (11, 12) is composed of a curved coupling portion (11-1, 11-2, 12-1, 12-2) to be installed in connection with each other, the coupling portion is a tape ( P) closed.
여기서, 상기 중간단열재(13)로 종래에는 E.P.S 보드(Expanded Polystyren Board)나 유리섬유보드(Glass Wool Board)등이 주로 사용되었으나 현재에는 비록 고가라는 단점을 있지만 방음과 단열 성능이 우수하다는 측면에서 발포 우레탄이 일반적으로 사용되고 있다.Here, the intermediate insulation material 13 is conventionally used as an EPS board (Expanded Polystyren Board) or a glass fiber board (Glass Wool Board), but at present, although the disadvantages of being expensive, but in terms of excellent sound insulation and insulation performance foam Urethane is generally used.
이에, 우레탄 판넬의 제조과정을 도2를 참고하여 간략하게 살펴보면, 아연도금강판이나 철판인 상하부 표면판재(11, 12)를 이송롤러로 각각 연속적으로 안내하면서 미도시된 포밍기로 결합부(11-1, 11-2, 12-1, 12-2)를 굴곡지게 형성시키고 나서, 하부 표면판재(12)상에 일정량의 우레탄수지액을 분사기(20)로 분사시킨 다음, 상하부 표면판재(11, 12)를 더블벨트(30)내로 진입시켜 가열기(40)로 우레탄수지액을 가열하면 우레탄수지액은 120℃ ~ 140℃의 온도로 발열반응을 하게 되고 이에 따라 부피가 팽창하면서 상하부 표면판재(11, 12)내에서 발포되어 충진된다. 이 때, 상하부 표면판재(11, 12)가 더블벨트(30)내로 진입할 때에 급지테이프(50) 공급기에 의해 테이프(P)가 공급되어 상하부 표면판재의 결합부 측면을 마감하여 판넬 내부에 발포공간을 형성시키게 된다. 이와 같이, 우레탄이 발포된 판넬은 소정의 간격으로 절단된 후 적재장에 차곡차곡 쌓여 적재된 상태에서 자연냉각되는 숙성공정을 통해 제조가 완료된다.Thus, briefly look at the manufacturing process of the urethane panel with reference to Figure 2, the upper and lower surface plate material (11, 12), which is a galvanized steel sheet or iron plate, respectively guided continuously to the feed roller, the coupling portion (11-) 1, 11-2, 12-1, and 12-2 are formed to bend, a predetermined amount of urethane resin liquid is injected into the injector 20 onto the lower surface plate 12, and then the upper and lower surface plate 11, 12) into the double belt 30 and the urethane resin solution is heated by the heater 40, the urethane resin solution is exothermic reaction at a temperature of 120 ℃ ~ 140 ℃, thereby expanding the volume of the upper and lower surface plates (11) And foamed in 12). At this time, when the upper and lower surface plate materials 11 and 12 enter the double belt 30, the tape P is supplied by the feeding tape 50 feeder to close the side of the coupling portion of the upper and lower surface plate materials and foam the inside of the panel. To form a space. In this way, the urethane foamed panel is cut through a predetermined interval and the manufacturing is completed through a aging process that is naturally cooled in a stacked state stacked on top of the stack.
하지만, 종래의 우레탄 판넬의 발포 우레탄은 자연냉각되는 숙성공정에서도 상당시간 고온으로 유지되므로 상당한 온도로 발열을 하게 되고, 상기 발열에 의해 표면판재(11, 12)가 뒤틀리거나 웨이브 형태로 변형되는 문제점이 있었다.However, since the urethane foam of the conventional urethane panel is maintained at a high temperature for a considerable time even in a natural cooling aging process, it generates heat at a considerable temperature, and the surface plates 11 and 12 are warped or deformed into waves by the heat generation. There was this.
본 고안은 상기 문제점을 해결하기 위해 안출된 것으로, 본 고안의 목적은 우레탄 판넬의 최종 제조공정인 우레탄 숙성공정에서 우레탄의 발열로 인해 표면판재가 변형되는 현상을 방지할 수 있는 우레탄 판넬을 제공하는 것이다.The present invention is devised to solve the above problems, an object of the present invention is to provide a urethane panel that can prevent the phenomenon of the surface plate deformation due to the heating of the urethane in the urethane maturing process of the final manufacturing process of the urethane panel will be.
상기 본 고안의 목적은 양측 단부에는 굴곡진 결합부가 형성되고 상기 결합부가 테이프로 마감되어 우레탄 발포공간을 형성하는 상하부 표면판재와; 상기 하부 표면판재의 내면에 접착고정된 단열보드와; 상기 상하부 표면판재의 발포공간에 발포 충진된 우레탄을 포함하여 구성된 것을 특징으로 하는 우레탄 판넬을 제공하는 것이다.An object of the present invention is the upper and lower surface plate material formed on both sides of the curved coupling portion and the coupling portion is closed with a tape to form a urethane foam space; An insulation board fixed to an inner surface of the lower surface plate material; It is to provide a urethane panel comprising a urethane foam filled in the foam space of the upper and lower surface plate material.
여기서, 상기 단열보드와 우레탄의 두께 비는 1:9 내지 6:4 중 어느 하나이고 상기 단열보드의 폭은 하부 표면판재의 폭의 80 내지 90% 의 어느 하나인 것이 바람직하며, 상기 단열보드는 난연성 E.P.S 인 것이 보다 바람직하다.Here, the thickness ratio of the insulation board and the urethane is any one of 1: 9 to 6: 4 and the width of the insulation board is preferably any one of 80 to 90% of the width of the lower surface plate material, the insulation board is It is more preferable that it is flame-retardant EPS.
상술한 본 고안의 목적은 첨부된 도면을 참조하여 후술되는 본 고안의 바람직한 실시예로부터 더욱 명확해질 것이다.The object of the present invention described above will become more apparent from the preferred embodiment of the present invention described below with reference to the accompanying drawings.
이하, 첨부된 도면을 참고하여 본 고안을 보다 상세하게 설명한다. 첨부된 도3은 본 고안에 따른 우레탄 판넬의 사시도이며, 도4는 도3은 본 고안에 따른 우레탄 판넬의 단면도이다.Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail. 3 is a perspective view of the urethane panel according to the present invention, Figure 4 is a cross-sectional view of the urethane panel according to the present invention.
본 고안에 따른 우레탄 판넬은 우레탄 숙성공정에서 우레탄의 발열로 인해 표면판재가 변형되는 현상을 방지할 수 있도록 판넬 내부에 단열보드가 내장된 것이 특징으로, 이를 위해 상하부 표면판재(110, 120), 단열보드(B) 및 발포우레탄(130)을 포함한다.Urethane panel according to the present invention is characterized in that the insulation board is built in the panel to prevent the deformation of the surface plate material due to the heating of the urethane in the urethane aging process, the upper and lower surface plate material (110, 120), Insulation board (B) and foamed urethane (130).
상기 상하부 표면판재(110, 120)는 그 재질이 철판 또는 아연도금강판이며, 판넬을 순차적으로 연결 설치할 수 있도록 양측 단부에는 굴곡진 결합부(110-1, 110-2, 120-1, 120-2)가 형성되어 있다. 여기서, 상기 결합부의 형상은 본 고안의 본질은 아닌 것으로 당업자는 필요에 따라 다양하게 변경설계 할 수 있음은 당연한다. 또한, 상기 결합부는 우레탄 발포시 우레탄이 외부로 삐져 나오는 것을 방지하기 위해 테이프(P)로 마감처리되어 있다. 따라서, 상하부 표면판재(110, 120)와 마감테이프(P)로 인해 판넬 내부는 우레탄이 발포될 발포공간이 형성되게 된다.The upper and lower surface plate (110, 120) is a steel plate or a galvanized steel plate, the bent coupling portion (110-1, 110-2, 120-1, 120-) at both ends so that the panel can be connected in sequence 2) is formed. Here, it is obvious that the shape of the coupling portion is not the essence of the present invention, and those skilled in the art can variously change the design as necessary. In addition, the coupling portion is finished with a tape (P) to prevent the urethane from leaking out when urethane foaming. Therefore, due to the upper and lower surface plate material 110, 120 and the finishing tape (P) inside the panel is to form a foam space for the urethane foaming.
상기 단열보드(B)는 우레탄이 판넬 내부에서 발포되기 전에, 하부 표면판재(120)의 내면에 접착 고정되며, 우레탄의 발열이 외부로 방출되어 표면판재가 변형되는 것을 방지하는 역할을 수행한다. 상기 단열보드(B)는 단열재로 일반적으로 사용되는 유리섬유보드(Glass Wool Board)을 사용하여도 무방하지만, 비용측면이나 중량 측면을 고려할 때 E.P.S 보드(Expanded Polystyren Board)를 사용하는 것이 바람직하다. 또한, 본 고안에 있어 단열보드로서 E.P.S 보드가 유리섬유보드에 비해 바람직한 또 다른 이유는 유리섬유보드는 섬유질이기 때문에 우레탄 발포시 우레탄이 유리섬유보드내로 침습되는 데, 이러한 침습으로 인해 우레탄과의 접착력이 약화되고 분사될 우레탄 수지액량에 오차가 생길 수 있지만, E.P.S 보드는 그러한 우려가 없다는 잇점이 있다.The insulation board (B) is adhesively fixed to the inner surface of the lower surface plate material 120 before urethane is foamed in the panel, and serves to prevent the heat generation of the urethane is released to the outside to deform the surface plate material. The insulating board (B) may be used as a glass wool board (Glass Wool Board) generally used as a heat insulating material, but considering the cost or weight side, it is preferable to use an E.P.S board (Expanded Polystyren Board). In addition, in the present invention, the EPS board is more preferable than the fiberglass board as the insulation board, because the fiberglass board is a fiber, and the urethane is infiltrated into the fiberglass board during urethane foaming. This weakening and error may occur in the amount of urethane resin to be sprayed, but the EPS board has the advantage that there is no such concern.
또한, 상기 E.P.S 보드는 난연성 E.P.S 보드인 것이 보다 가장 바람직한 데, 이는 난연성 E.P.S보드는 일반 E.P.S보드 보다는 물론 발포 우레탄 보다도 난연성이 우수하기 때문에 판넬 내부에 내장된 난연성 E.P.S 보드에 의해 판넬 전체적인 난연성을 향상시킬 수 있기 때문이다.In addition, the EPS board is more preferably a flame-retardant EPS board, which is because the flame retardant EPS board is excellent flame retardant than polyurethane foam as well as the general EPS board to improve the overall flame retardancy by the flame-retardant EPS board embedded in the panel. Because it can.
한편, 상기 단열보드(B)가 하부 표면판재(120)의 내면에 접착고정되면 판넬 내부의 발포공간에는 우레탄 수지액이 분사되어 발포 충진되는 데, 여기서 상기 E.P.S보드(120)와 우레탄(130)의 두께 비는 1:9 내지 6:4 중 어느 하나인 것이 바람직한 데, E.P.S보드의 두께비가 우레탄 두께비의 1 미만이면 E.P.S보드의 우레탄 발열차단기능이 약화되어 요구하는 성능을 만족하기 어렵기 때문이다.On the other hand, when the insulation board (B) is fixed to the inner surface of the lower surface plate material 120, the urethane resin liquid is injected into the foam space inside the panel is foamed and filled, wherein the EPS board 120 and the urethane 130 It is preferable that the thickness ratio of is 1: 9 to 6: 4, because if the thickness ratio of the EPS board is less than 1 of the urethane thickness ratio, the urethane heat shielding function of the EPS board is weakened and it is difficult to satisfy the required performance. .
또한, 상기 단열보드(B)의 폭은 하부 표면판재(120)의 폭의 80 내지 90% 의 어느 하나인 것이 바람직하다. 이로 인해 결합부 내부 공간으로도 발포 우레탄이 충진되어 도5에 도시된 바와 같이 판넬을 순차적으로 연결한 후 볼트와 같은 결합수단을 통해 결합시킬 때 상대적으로 강도가 강한 우레탄으로 인해 판넬 상호간의 결합강도를 향상시킬 수 있게 되기 때문이다.In addition, the width of the insulating board (B) is preferably any one of 80 to 90% of the width of the lower surface plate material 120. Due to this, the foamed urethane is also filled into the inner space of the joining portion, and as shown in FIG. Because it can be improved.
이와 같이 구성된 본 고안에 따른 우레탄 판넬의 제조방법 및 그 효과를 알아본다.It looks at the manufacturing method and the effect of the urethane panel according to the present invention configured as described above.
도6에 도시된 바와 같이, 상하부 표면판재(110, 120)를 연속적으로 이송롤러를 통해 이송시키는 데, 상하부 표면판재(110, 120)는 미도시된 포밍기에 의해 그 양측단부에 결합부(110-1, 110-2, 120-1, 120-2)가 형성되며, 이송되는 하부 표면판재에는 접착제 분무기(210)에 의해 접착제가 도포된다. 그리고, 단열부재 공급롤러에 의해 단열부재(B)가 하부 표면판재(120)상에 적재되고 가압롤러(215)에 의해 단열부재(B)가 하부 표면판재(120)상에 견고하게 접착되게 된다. 그 후, 우레탄 수지액 분무기(220)에 의해 분무된 우레탄 수지액은 더블벨트(230)를 통과하면서 가열기(240)의 가열에 의해 발포되어 판넬 내부에 충진된 후 소정의 길이로 절단되게 되어 적재장으로 옮겨져 적재된 후 자연냉각되는 숙성공정을 거치게 된다.As shown in FIG. 6, the upper and lower surface plate members 110 and 120 are continuously transferred through the feed rollers, and the upper and lower surface plate members 110 and 120 are coupled to the both ends of the upper and lower surface plate members 110 and 120 by a forming machine. -1, 110-2, 120-1, 120-2 is formed, the adhesive is applied to the lower surface plate material to be transported by the adhesive sprayer 210. Then, the heat insulating member B is loaded on the lower surface plate 120 by the heat insulating member supply roller, and the heat insulating member B is firmly adhered on the lower surface plate 120 by the pressure roller 215. . Thereafter, the urethane resin liquid sprayed by the urethane resin liquid sprayer 220 is foamed by heating of the heater 240 while passing through the double belt 230 and filled into the panel, and cut into a predetermined length. After being transferred to the cabinet and loaded, it undergoes a maturation process that is naturally cooled.
이와 같이 제조되는 본 고안에 따른 우레탄 판넬은 판넬 내부에 내장된 E.P.S보드에 의해 자연냉각되는 숙성공정에서 발포 우레탄에서 발생하는 열이, 도7에 도시된 바와 같이 그 상부나 하부에 적재된 판넬로 전달되는 것을 차단하므로, 우레탄의 발열로 인해 표면판재(110, 120)가 변형되는 현상을 방지할 수 있다는 잇점이 있다.The urethane panel according to the present invention manufactured as described above is a panel loaded with heat generated from the urethane foam in the maturation process naturally cooled by the EPS board embedded in the panel, as shown in FIG. 7. Since the transmission is blocked, there is an advantage that the phenomenon that the surface plate (110, 120) is deformed due to the heating of the urethane.
또한, 본 고안에 따른 우레탄 판넬은 E.P.S보드(B)가 마련된 하부 표면판재(120)를 외벽으로 하여 시공하면, 하계에 철판인 표면판재가 고온이 되어 자체 변형이 생길 경우 우레탄 보다 상대적으로 밀도가 떨어지는 E.P.S보드가 표면판재에 대응하여 변형을 하고 표면판재가 저온이 되어 원상복귀하는 경우에도 이에 대응하여 원상복귀함으로써 표면판재가 휘거나 틀어지는 문제점도 해결할 수 있다는 잇점이 있다.In addition, when the urethane panel according to the present invention is constructed with the lower surface plate 120 provided with an EPS board (B) as an outer wall, the surface plate material, which is an iron plate in the summer, becomes a high temperature, so that its deformation becomes relatively higher than that of urethane. Even if the falling EPS board deforms in response to the surface plate and the surface plate returns to its original state due to the low temperature, the problem that the surface plate is bent or distorted can also be solved by returning to the original state.
또한, 본 고안에 있어 내장된 단열보드를 난연성 E.P.S 보드로 하게 되면 자기 소화성인 우레탄 판넬의 난연성을 보강하여 화재 안전성을 높일 수 있다는 잇점이 있다.In addition, in the present invention, the built-in insulation board is a flame-retardant E.P.S board has the advantage that it is possible to enhance the fire safety by reinforcing the flame retardancy of the self-extinguishing urethane panel.
이상에서 설명한 바와 같이, 본 고안에 따른 우레탄 판넬은 우레탄 판넬 내부에 우레탄의 발열을 차단할 수 있는 단열보드를 내장함으로써 우레탄 판넬의 최종 제조공정인 우레탄 숙성공정에서 우레탄의 발열로 인해 표면판재가 변형되는 현상을 방지할 수 있다는 효과가 있다. As described above, the urethane panel according to the present invention has a surface board that is deformed due to the heating of the urethane in the urethane aging process, which is the final manufacturing process of the urethane panel by embedding an insulating board that can block the heating of the urethane inside the urethane panel There is an effect that can prevent the phenomenon.
또한, 본 고안에 있어, 내장된 단열보드를 난연성 E.P.S 보드로 하게 되면 자기 소화성인 우레탄 판넬의 난연성을 보강하여 화재 안전성을 높일 수 있다는 효과가 있다.In addition, in the present invention, if the built-in insulation board to the flame retardant E.P.S board has the effect of enhancing the fire safety by reinforcing the flame resistance of the self-extinguishing urethane panel.
