No, it is cut by the cutting blade of the cutting means in step S1 to a small size, preferably about 1 ~ 5cm in width and finely cut to facilitate its handling and filling inside the mold, the outside in the state filled in the hopper Joined while being put into the mold and pressurized in the state of surface melting by hot air supplied from So that when the lungs can be made PE foam pieces between compact and also robust joint.
상기 단계 S2에서는 작게 커팅된 폐 PE폼 조각을 호퍼에 투입하고 열풍을 가하게 되는데, 이 열풍은 호퍼 내부로 전체적으로 균일하게 공급이 이루어질 수 있도록 호퍼의 하부와 측부측에 열풍공급구를 형성하는 것이 바람직하며, 이때 공급되는 열풍의 온도는 PE폼의 용융온도(약 120℃)보다 높은 약 150℃정도의 열풍을 공급하여 PE폼 조각 사이사이의 공극을 통해 전체적으로 공급되면서 PE폼 조각의표면을 용융시키게 된다.In step S2, a small piece of waste PE foam is cut into the hopper and hot air is applied. The hot air is preferably formed at the bottom and side of the hopper so that the hot air is uniformly supplied into the hopper. At this time, the hot air temperature is supplied to the hot air of about 150 ℃ higher than the melting temperature of the PE foam (about 120 ℃) to supply through the pores between the PE foam pieces to melt the surface of the PE foam pieces. do.
호퍼 내부에 적정시간동안 열풍을 공급한 후에는 단계 S3에서 표면이 용융된 폐 PE폼 조각을 몰드에 투입한 후 몰드 상부에서 가압판을 눌러 표면이 용융된 PE폼 조각들을 상호 압착시키게 되는데, 이때에는 약 15분 정도 가압판으로 가압시킨 상태를 유지함으로써 재접합되는 PE폼의 결합력을 높이고 탈형후에도 안정된 형태를 유지할 수 있도록 하며, 가압판을 누른 상태에서 압축성형된 PE폼 보드가 서서히 냉각되도록 한다.After the hot air is supplied to the inside of the hopper for a predetermined time, the waste PE foam pieces having the molten surface are introduced into the mold in step S3, and the pressing plates are pressed from the upper part of the mold to compress the PE foam pieces with the molten surface. Maintaining the pressurized state with the pressure plate for about 15 minutes to increase the bonding strength of the re-bonded PE foam and to maintain a stable form even after demolding, and to slowly cool the compression-molded PE foam board while pressing the pressure plate.
또, 단계 S4에서는 가압성형된 재생 PE폼 보드를 몰드로부터 꺼내 원하는 두께로 슬라이싱을 하거나 또는 몰드에서 꺼낸 두께 그대로를 사용할 수 있는데, 이때에는 원하는 규격에 맞게 절단해주기만 하면 된다.In addition, in step S4, the press-formed recycled PE foam board may be taken out of the mold and sliced to a desired thickness or may be used as it is taken out of the mold.
마지막 단계인 S5에서는 재생 PE폼을 프린트 강판과 열융착방법 또는 공지의 접착제를 사용하여 접합시키면 건축용 패널이 완성된다.In the final step S5, the recycled PE foam is bonded to the printed steel sheet using a thermal fusion method or a known adhesive to complete the building panel.
도 2는 본 고안의 일 실시예에 의한 건축용 패널을 도시한 일부절개사시도로서, 본 실시예에 도시된 패널은 PE폼 조각(1)이 가압 열융착된 PE폼 보드(2)의 일면에만 프린트 강판(3)이 접합된 홑겹 패널로, 이는 지붕용 패널이나 기타 벽체용 패널로 사용될 수 있다.2 is a partial cutaway perspective view showing a building panel according to an embodiment of the present invention, the panel shown in this embodiment is printed on only one surface of the PE foam board (2) where the PE foam pieces (1) is pressurized heat-sealed It is a single layer panel to which the steel sheet 3 is bonded, which can be used as a roof panel or other wall panels.
도 2의 실시예에 의한 건축용 패널은 PE폼 조각(1)이 재접합된 PE폼 보드(2)가 외부로 노출되어 있으며, 그럼에도 불구하고 PE폼 보드(2)를 이루는 PE폼 조각(1)은 상호 열융착되어 있으므로 부스러짐이나 분리가 발생되지 않으며, 몰드 내부에서 성형되고 탈형후 적정두께로 슬라이싱 되므로 원하는 표면형상을 얻을 수 있다.In the building panel according to the embodiment of FIG. 2, the PE foam board 2 to which the PE foam pieces 1 are re-bonded is exposed to the outside, and the PE foam pieces 1 forming the PE foam board 2 nevertheless. Since they are mutually heat-sealed, no chipping or separation occurs, and the desired surface shape can be obtained because they are molded in the mold and sliced to an appropriate thickness after demolding.
도 3은 본 고안의 다른 실시예에 의한 샌드위치 패널의 사시도이고, 도 4는 도 3에 도시된 샌드위치 패널의 단면도로서, 본 실시예에서는 상기한 방법에 의해 생산된 PE폼 보드(2)의 양면에 프린트 강판(3,3')을 접합시킨 것이며, 이는 건물의 내,외벽용 패널이나 칸막이용 패널 등 여러 용도로 사용할 수 있다.3 is a perspective view of a sandwich panel according to another embodiment of the present invention, Figure 4 is a cross-sectional view of the sandwich panel shown in Figure 3, in this embodiment both sides of the PE foam board (2) produced by the method described above The printed steel sheets 3, 3 'are bonded to each other, and can be used for various purposes such as panels for interior and exterior walls of a building and partition panels.
또, 본 고안은 도면상에는 도시되어 있지 않으나 상기한 재생 PE폼을 이중 샌드위치 패널 즉, 중간에 프린트 강판이 개재되고 이 프린트 강판의 양측에 각각 재생 PE폼이 부착되며, 이 재생 PE폼의 양 외측에 다시 프린트 강판이 부착된 형태로도 제작할 수 있다.In addition, the present invention is not shown in the drawings, but the above-mentioned recycled PE foam is a double sandwich panel, that is, a printed steel sheet is interposed in the middle, and the recycled PE foam is attached to both sides of the printed steel sheet, both sides of the recycled PE foam. It can also be produced in the form of a printed steel sheet attached to the back.
상기한 바와 같은 본 고안의 폐 PE폼을 충진재로 사용하는 건축용 패널은 그동안 폐기가 곤란하고 제품의 생산시 어쩔 수 없이 발생하는 손실(loss)부분의 폐기물 및 수거된 제품을 사용하므로 원재료의 구입에 대한 비용부담이 없고, 이들 원재료를 잘게 컷팅한 후 표면을 용융시킨 상태에서 가압 융착시켜 재생 PE폼 보드를 생산하므로 자원의 재활용측면 및 환경보호측면에서도 상당히 유리하며, 재생된 PE폼 보드는 그대로 또는 필요한 두께로만 절단하여 프린트 강판과 접합하는 것에의해 건축용 패널을 생산할 수 있으므로 비교적 간단한 공정을 거쳐 제품이 생산되어 제품의 제조코스트도 낮아 기존의 다른 건축용 패널보다 난연성 및 차음성과 압축강도가 우수한 성능을 가지면서도 저렴한 비용으로 보급할 수 있는 잇점을 갖는다.Building panels using the waste PE foam of the present invention as a filler as described above is difficult to dispose during that time and use the waste part and the collected products that are inevitably generated during the production of the product. There is no cost burden, and these raw materials are cut finely and pressurized and fused in the molten state to produce recycled PE foam board, which is very advantageous in terms of recycling and environmental protection of recycled PE foam board. As it is possible to produce building panels by cutting only to the required thickness and joining with the printed steel sheet, the product is produced through a relatively simple process, and the manufacturing cost of the product is low. Therefore, it has better flame retardancy, sound insulation, and compressive strength than other building panels. It has the advantage that it can be supplied at low cost.
이와 같이 구성된 본 고안의 폐 폴리에틸렌 폼을 충진재로 사용하는 건축용 패널은 일반 PE폼을 사용한 패널과 같이 소재 자체가 자기소화성을 갖는 난연기능을 가짐과 더불어 재생시 다시 압축되므로 밀도가 높아 불이 쉽게 붙지 않을 뿐만 아니라 알루미늄이 코팅된 PE폼을 사용할 경우 난연성은 더욱 우수하고, 압축강도와 차음성 또한 일반 PE폼이나 E.P.S패널에 비하여 우수하며, 그럼에도 불구하고 이의 제조비용은 기존 PE폼과 비교할 수 없을 만큼 저렴하므로 기존의 E.P.S패널 및 PE폼 보다도 안전하고 구조적인 강도도 우수한 고품질의 건축용 패널을 염가로 제공할 수 있는 실용적인 효과를 갖는다.The building panel using waste polyethylene foam of the present invention configured as described above has a flame retardant function that has the self-extinguishing property as the panel using general PE foam, and is compressed again during regeneration, so that the fire is not easily caught. In addition, the use of aluminum-coated PE foam is more excellent in flame retardancy, and its compressive strength and sound insulation are also superior to that of ordinary PE foam or EPS panels. Nevertheless, its manufacturing cost is incomparable with that of conventional PE foam. Since it is inexpensive, it has a practical effect that can provide a high quality building panel which is safer and structural strength superior to existing EPS panels and PE foams at low cost.
