이하, 본 발명의 바람직한 실시예를 첨부한 도면에 의거하여 설명하면 다음과 같다. 도 1은 본 발명의 일 실시예를 보인 사시도로서, 본 발명은 도시된 바와 같이, EVA와 PE를 포함하여 발포성형된 제1EVA-PE발포시트(10)와, EVA와 PE를 포함하여 발포성형되며 상기 제1EVA-PE발포시트(10)에 비해 상대적으로 밀도가 낮은 제2EVA-PE발포시트(20)가 서로 교호되게 반복적으로 적층되어 이루어진 충격흡수방음발포보드(30)이다. Hereinafter, preferred embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a perspective view showing an embodiment of the present invention, the present invention, as shown, foamed molding including the first EVA-PE foam sheet 10, including EVA and PE, foaming molding including EVA and PE The second EVA-PE foam sheet 20 having a relatively lower density than the first EVA-PE foam sheet 10 is alternately and repeatedly stacked alternately with each other to be a shock-absorbing sound-absorbing foam board 30.
상기 제1,2EVA-PE발포시트(10,20)는 EVA수지와 PE수지를 주성분으로 하고, 이에 고무, 프로세스오일, 가교제, 발포제와 함께 카본블랙, 숯, 제올라이트 등의 충전제 및 기타 첨가제가 혼합되어 이루어진 원료로 이루어진다. 이때 고밀도인 제1EVA-PE발포시트(10)는 저밀도인 제2EVA-PE발포시트(20)에 비해 카본블랙과, 숯과 제올라이트 및 고무의 혼합량이 상대적으로 적게 혼합되도록 각 원료들의 혼합량이 조절되며, 발포제나 가교제 등의 양이 조절되어 각 시트(10,20)들이 발포 후, 서로 다른 밀도를 갖도록 제작된다. The first and second EVA-PE foam sheets 10 and 20 are mainly composed of EVA resin and PE resin, and are mixed with rubber, process oil, crosslinking agent, foaming agent, fillers such as carbon black, charcoal, zeolite, and other additives. It is made of raw material. At this time, the high density of the first EVA-PE foam sheet 10 is adjusted compared to the low density of the second EVA-PE foam sheet 20, the mixing amount of each raw material is adjusted so that the mixed amount of carbon black, charcoal, zeolite and rubber is relatively less mixed. , The amount of the blowing agent or crosslinking agent is controlled, and the sheets 10 and 20 are manufactured to have different densities after foaming.
이와 같은 구성을 갖는 본 발명은 다음과 같이 제작된다. 먼저, 전술한 바와 같은 혼합량에 기초하여 고밀도인 제1예비EVA-PE발포시트와, 제1예비EVA-PE발포시트에 비해 상대적으로 저밀도인 제2예비EVA-PE발포시트를 소정두께로 성형한다. 시트의 성형시에는 원료 중에 혼합된 발포제가 분해되지 않도록 발포제의 분해온도보다 낮은 온도에서 성형한다. 그리고 성형된 시트들을 서로 교호되게 반복적으로 적층시킨다. 이때에는 상대적으로 저밀도인 제2예비EVA-PE발포시트가 보드(30)의 상하 외측면을 형성하도록 시트(10,20)들을 적정 개수로 적층시킨다. 경우에 따라서는 서로 다른 밀도를 가지는 시트를 3종류 또는 그 이상으로 준비하여 교호로 적층할 수도 있다. The present invention having such a configuration is produced as follows. First, the first preliminary EVA-PE foam sheet having a high density and the second preliminary EVA-PE foam sheet having a relatively lower density than the first preliminary EVA-PE foam sheet are molded to a predetermined thickness based on the mixing amount as described above. . In forming the sheet, the blowing agent mixed in the raw material is molded at a temperature lower than the decomposition temperature of the blowing agent so as not to decompose. The molded sheets are then repeatedly stacked alternately with each other. In this case, the second preliminary EVA-PE foam sheet having a relatively low density stacks the sheets 10 and 20 in an appropriate number so as to form upper and lower outer surfaces of the board 30. In some cases, three or more types of sheets having different densities may be prepared and laminated alternately.
이어서 가열프레스 등으로 적층된 예비EVA-PE발포시트를 가열가압하는데, 시트에 혼합된 발포제가 분해하도록 가열가압한다. 이와 같이 하면 각 시트들이 발포되면서 서로 융착된다. 경우에 따라서는 적층된 예비EVA-PE발포시트를 단순히 가열하여 발포, 융착시킬 수도 있다.Subsequently, the preliminary EVA-PE foam sheet laminated by a heat press or the like is heated and pressurized, and is heated and pressurized to decompose the blowing agent mixed in the sheet. In this way, the sheets are foamed and fused together. In some cases, the laminated pre-EVA-PE foam sheet may be simply heated to be foamed and fused.
이와 같이 비발포된 시트를 적층하여 발포와 동시에 시트들이 부착되도록 하는 것은, 기발포된 시트를 접착제로 접착하여 방음보드를 제작하는 것에 비해 공정이 간단하여 코스트가 저렴하기 때문이다. The lamination of the non-foamed sheet as described above allows the sheets to be attached at the same time as the foaming because the process is simpler and the cost is lower than that of manufacturing the soundproof board by adhering the foamed sheet with an adhesive.
바람직하게는 보드(30) 제작시 각 예비EVA-PE발포시트들을 상하로 대칭되게 적층하여 발포부착시킨 다음, 상하대칭되는 위치의 시트 중앙부를 수평방향으로 절단하여 2개의 보드(30)를 제작한다. 이와 같이 하면, 절단된 면이 보드(30)의 일측 표면을 형성하게 되는데, 이 면은 시트의 중앙부를 절단하여 형성된 면이므로 시트의 표면에 비해 상대적으로 오픈셀이 많이 배치되어 있다. 따라서 이 경우에는 시트의 표면이 방음보드의 표면을 이루는 경우에 비해 보드(30)의 흡음율이 다소 상승된다.Preferably, when the board 30 is fabricated, each preliminary EVA-PE foam sheet is symmetrically stacked up and down to be foamed, and then two boards 30 are manufactured by cutting the center of the sheet in the horizontally symmetrical position in the horizontal direction. . In this case, the cut surface forms a surface of one side of the board 30. Since this surface is a surface formed by cutting the center portion of the sheet, the open cells are arranged relatively more than the surface of the sheet. Therefore, in this case, the sound absorption rate of the board 30 is slightly increased as compared with the case where the surface of the sheet forms the surface of the soundproof board.
이상과 같은 본 발명은 건축물의 슬라브시공시 철근콘크리트(2) 위에 시공되는데, 서로 다른 밀도를 가지는 시트(10,20)들이 교호로 적층되어 이루어지므로, 다양한 주파수대의 소음이 흡음되며, 특히 소음이 각 시트(10,20)들 사이의 경계면에서 반사되어 간섭, 상쇄되는 과정이 반복적으로 행해지므로 소음의 제거효율이 상승된다. The present invention as described above is constructed on the reinforced concrete (2) during the construction of the slab of the building, because the sheets 10 and 20 having different densities are alternately stacked, noise of various frequency bands is absorbed, in particular noise Since the process of reflection, interference, and offsetting at the interface between the sheets 10 and 20 is repeatedly performed, noise removal efficiency is increased.
또한, 소음이 보드(30)에 흡음됨에 따라 소음이 열에너지로 전환되어 열이 발생되는데, 특히, 본 발명에서는 시트(10,20)에 혼합된 카본블랙에 의해 발생된 열이 원활하게 확산되므로 보드(30)의 흡음효율이 한층 더 상승된다. 필요에 따라서는 시트(10,20) 성형시 동분말을 혼합할 수도 있는데, 이와 같이 동분말이 혼합되면 동분말의 열전도성에 의해 소음이 흡음됨에 따라 발생되는 열이 더욱 효과적으로 확산되므로 방음보드(30)의 흡음효율이 한층 더 상승된다. 또한, 동분말에 의해 수맥파 차단효과 등도 기대될 수 있다. In addition, as the noise is absorbed by the board 30, the noise is converted into thermal energy and heat is generated. In particular, in the present invention, the heat generated by the carbon black mixed in the sheets 10 and 20 is smoothly diffused. The sound absorption efficiency of 30 is further increased. If necessary, the copper powder may be mixed when the sheet 10 and 20 are formed. In this way, when the copper powder is mixed, the heat generated as the noise is absorbed by the thermal conductivity of the copper powder is more effectively diffused. ) The sound absorption efficiency is further increased. In addition, by the same powder can also be expected to the water wave blocking effect.
도 2와 도 3은 본 발명의 다른 실시예를 보인 것으로, 보드(30)의 저면을 형성하는 시트(20b)의 외측면에 엠보싱돌기(26)가 형성된 것이다. 상기 엠보싱돌기(26)는 보드(30)가 시공된 상태에서 방음보드(30)와 슬라브(2) 사이에 공간부(28)가 형성되는 들뜸시공을 하기 위한 것이다. 상기 엠보싱돌기(26)가 전후좌우로 연결된 형상을 가지면 보드(30)와 슬라브(2) 사이에 형성되는 공간부(28)가 다수개로 구획되어, 각 공간부(28)로 흡입된 소음은 공간부(28)에서 공명을 일으켜 소음이 증대될 우려가 있다. 따라서 바람직하게는 도 3에 도시된 바와 같이, 상기 공간부(28)가 구획되지 않고 보드(30)의 전 면적에 걸쳐 상호 연통되도록, 상기 엠보싱돌기(26)는 전후좌우로 이격되게 형성된다.2 and 3 show another embodiment of the present invention, wherein the embossing protrusions 26 are formed on the outer surface of the sheet 20b forming the bottom surface of the board 30. The embossing projection 26 is for the lifting construction in which the space portion 28 is formed between the soundproof board 30 and the slab 2 in the state where the board 30 is constructed. When the embossing projection 26 has a shape connected in front, rear, left and right, the space portion 28 formed between the board 30 and the slab 2 is divided into a plurality of spaces, and the noise sucked into each space portion 28 is space. There is a fear that the noise is increased by causing resonance in the unit 28. Thus, as shown in FIG. 3, the space portion 28 is preferably not communicated with each other over the entire area of the board 30. The embossing protrusion 26 is formed spaced apart from front to back, left and right.
도 4와 도 5는 상기 엠보싱돌기(26)가 다양한 형상으로 변형될 수 있음을 보여준다. 4 and 5 show that the embossing protrusion 26 can be modified in various shapes.
이상에서는 본 발명이 서로 다른 밀도를 가지는 EVA-PE발포시트들이 적층되어 이루어진 것으로 설명하였으나, 경우에 따라서는 셀의 크기가 서로 다른 EVA-PE발포시트들이 교호로 적층되어 이루어질 수도 있다. 셀의 크기가 크면 오픈셀이 형성된 가능성이 높아지고, 셀의 크기가 상대적으로 작으면 오픈셀이 형성될 가능성이 저하되어 독립셀이 형성된 가능성이 높아진다. 그리고 오픈셀이 많은 경우에는 독립셀이 많은 경우에 비해 흡음특성이 상승되며, 상대적으로 독립셀이 많은 경우에는 흡음성 보다는 차음특성 다소 상승된다. 따라서 본 발명에서는 셀의 크기를 0.5㎜기준으로 하여 셀의 직경이 대략 0.5㎜이하인 EVA-PE발포시트와, 셀의 직경이 대략 0.5~2㎜인 EVA-PE발포시트가 교호로 적층되어 이루어져서 다양한 주파수대의 소음에 대한 흡차음특성을 가지게된다. In the above description, the present invention has been described in that the EVA-PE foam sheets having different densities are laminated, but in some cases, the EVA-PE foam sheets having different cell sizes may be alternately stacked. If the size of the cell is large, the possibility of forming an open cell increases. If the size of the cell is relatively small, the possibility of forming an open cell decreases, thereby increasing the possibility of forming an independent cell. In the case of a large number of open cells, the sound absorption characteristics are increased compared to the large number of independent cells. Accordingly, in the present invention, a cell size of 0.5 mm is used as the base of the EVA-PE foam sheet having a diameter of about 0.5 mm or less, and an EVA-PE foam sheet having a diameter of about 0.5 to 2 mm is alternately stacked. It has the sound absorbing and insulating characteristic against noise of frequency band.
이와 같이 셀의 크기가 서로 다른 EVA-PE발포시트들이 교호로 적층되어 이루어지는 경우에도 전술한 바와 같이, 시트들이 발포와 융착이 동시에 이루어지도록 하는데, 이때에는 발포 후 직경이 0.5㎜ 이하인 셀과 직경이 0.5~2㎜인 셀을 갖는 두 종류의 예비EVA-PE발포시트를 만들고 이들을 교호로 적층한 후 가열가압 또는 가열하여 발포와 동시에 융착되도록 한다. 발포시트의 셀크기 조절은 원료의 혼합비율이나 발포조건 등에 따라 당업자가 용이하게 실시할 수 있는 정도의 기술이므로 상세한 설명은 생략한다. As described above, even when EVA-PE foam sheets having different cell sizes are alternately stacked, as described above, the sheets are foamed and fused at the same time. In this case, the cells having a diameter of 0.5 mm or less after foaming Two kinds of preliminary EVA-PE foam sheets having cells of 0.5 ~ 2mm are made, and they are laminated alternately, and then pressurized or heated to be fused simultaneously with foaming. Cell size control of the foam sheet is a technique that can be easily carried out by those skilled in the art according to the mixing ratio of the raw material, foaming conditions, and the like, detailed description thereof will be omitted.
또한, 이상에서는 본 발명이 층간소음제로 사용된 것을 예로 들었으나, 본 발명은 층간소음제 뿐만 아니라 벽체 내장제 또는 건축물의 바닥재나 벽재 등으로도 사용이 가능하다. In addition, although the present invention has been used as an example of the interlayer noise absorbent, the present invention can be used not only as an interlayer noise absorber, but also as a floor covering or wall material of a building.
이상에서와 같이 본 발명에 의하면, 밀도 또는 셀의 크기가 다른 발포시트를 교호되게 적층하여 이루어지므로 다양한 주파수대의 소음에 대한 방음효과가 우수하며, 이에 따라 외부소음이 실내로 유입되는 것이 효과적으로 방지되어 쾌적한 실내환경을 조성할 수 있으며, 특히, 비발포된 시트들이 발포와 동시에 융착되도록 구성되어 제작이 용이하여 코스트도 저럼한 새로운 구성의 충격흡수방음발포보드를 제공할 수 있다. As described above, according to the present invention, since the foam sheets having different densities or cell sizes are alternately laminated, the soundproof effect is excellent against noise of various frequency bands, and thus, external noise is effectively prevented from entering the room. It is possible to create a comfortable indoor environment, in particular, the non-foamed sheet is configured to be fused at the same time as the foam is easy to manufacture and can provide a shock-absorbing sound-absorbing foam board of a new configuration with low cost.
