Description

강화 페놀 폼 보드{Phenol board having Honeycomb structure}Phenol board having Honeycomb structure < RTI ID = 0.0 >

본 발명은 강화 페놀 폼 보드에 관한 것이다.The present invention relates to a reinforced phenol foam board.

최근 단열 및 소방기준이 강화되는 상황에서 단열재 자체의 성능 개선을 위한 많은 시도가 진행되고 있다. 건물의 시공 공법에 있어서도, 종래의 내단열 공법을 벗어나서 단열재를 건물의 외벽에 시공하는 이른바 외단열시스템이 주목되고 있다.Recently, a lot of attempts have been made to improve the performance of the insulation itself in a situation where insulation and firefighting standards are strengthened. Also in the construction method of a building, a so-called external heat insulating system for installing a heat insulating material on an outer wall of a building after a conventional heat insulating method is attracting attention.

상기 외단열시스템에 사용될 수 있는 단열용 판재에는, 발포폴리스틸렌, 글라스울, 우레탄발포보드, 페놀수지발포보드 등이 제안되고 있다. As the heat insulating plate material which can be used in the above-mentioned external heat insulating system, expanded polystyrene, glass wool, urethane foam board, phenolic resin foam board and the like have been proposed.

그런데 상기한 폴리스틸렌이나 우레탄 등의 합성수지로 제작한 단열용 판재는, 내열성이 부족하여 화재 발생시 유독가스를 방출하고, 더욱이 내압성과 내압축성이 떨어져 단열용 판재로서 그 성능이 좋지 못하였다. 또한 상기 페놀수지발포보드로 성형된 단열용 판재는 내열성 및 내화성은 우수하지만 내압성과 내충격성과 굴곡탄성률이 좋지 못하다는 한계를 가진다.However, the heat insulating plate made of synthetic resin such as polystyrene or urethane has insufficient heat resistance, releases toxic gas when a fire occurs, and has poor pressure resistance and compressive resistance. In addition, the heat insulating plate material molded from the phenolic resin foam board is excellent in heat resistance and fire resistance, but has limitations in terms of pressure resistance, impact resistance and flexural modulus.

이러한 페놀수지발포보드의 문제를 해결하기 위하여, 하니컴재의 육각 셀 내부에 페놀수지를 주입 및 발포시키는 타입의 이른 바, 페놀 폼 보드도 제안된 바 있다. In order to solve the problem of the phenolic resin foam board, a so-called phenol foam board of the type which injects and foams the phenolic resin into the hexagonal cell of the honeycomb material has been proposed.

도 1은 종래의 패놀 폼 보드의 일부를 도시한 측단면도이다.1 is a side sectional view showing a part of a conventional phenol foam board.

도시한 바와같이, 종래의 패놀 폼 보드(11)는, 육각의 셀이 형성되며 일정두께의 평판의 형태를 취하는 하니컴재(13)와, 상기 허니텀재(13)의 각 셀 내부에 충진되는 페놀폼(15)과, 상기 허니컴재(13)의 상면과 저면에 밀착 결합하는 표면재(17)로 구성된다.As shown in the figure, the conventional phenol foam board 11 includes a honeycomb material 13 having a hexagonal cell shape and having a plate thickness of a predetermined thickness, and a honeycomb material 13 having phenol A foam 15 and a surface material 17 which is in tight contact with the upper and lower surfaces of the honeycomb material 13.

상기 하니컴재(13)는, 평판의 형태를 취하며 그 내부에 허니컴 구조의 육각 셀이 밀집 형성된 것으로서 두께 방향으로 일정 단면을 갖는다. 또한 상기 페놀폼(15)은 상기 각각의 셀에 충진되며 셀의 내벽면에 밀착 고정된 상태로 유지된다. 상기 페놀폼(15)은 페놀이 포함되어 있는 혼합액을 상기 셀의 내부에 수용시킨 상태로 발포시켜 상기 셀의 내부를 채운 구조를 갖는다.The honeycomb material 13 is in the form of a flat plate, in which hexagonal cells of a honeycomb structure are densely packed and have a certain cross section in the thickness direction. Further, the phenol foam 15 is filled in each of the cells and is maintained in a state of being closely fixed to the inner wall surface of the cell. The phenol foam 15 has a structure in which a mixed liquid containing phenol is foamed in a state of being accommodated in the cell to fill the inside of the cell.

상기 표면재(17)는, 상기 하니컴재(13)의 양면을 커버하며 하니컴재(13)와 페놀폼(15)을 보호하여 외부로 미감을 구현하는 판상 부재이다. 상기 표면재(17)는 알루미늄 재질이며 에폭시 접착제를 통해 하니컴재(13) 및 페놀폼(15)의 외측에 접착 고정된다. The surface member 17 is a plate-shaped member covering both surfaces of the honeycomb member 13 and protecting the honeycomb member 13 and the phenol foam 15 to realize a feeling of externality. The surface material 17 is made of aluminum and adhesively fixed to the outside of the honeycomb material 13 and the phenol foam 15 through an epoxy adhesive.

그런데 상기 구조를 갖는 종래의 페놀 폼 보드(11)는 그 제작방법이 매우 번거롭다는 단점이 있었다.However, the conventional phenol foam board 11 having the above-described structure has a disadvantage that it is very troublesome to manufacture.

상기 페놀 폼 보드(11)를 제작하는 공정에는, 페놀과, 포르말린과, 젓산과, 가성소다와, 발포제 등이 적정 비율로 혼합된 교반용액을, 준비된 용기내에 부어 넣은 상태로, 상기 하니컴재(13)를 수평으로 내려 상기 교반용액에 침지시킨 후, 발포를 진행하는 과정을 포함한다.The step of preparing the phenol foam board 11 includes a step of pouring a stirred solution containing phenol, formalin, lactic acid, caustic soda, foaming agent, and the like in a suitable ratio into a prepared container, 13) is lowered horizontally and immersed in the stirring solution, followed by foaming.

상기 발포를 통해 하니컴재(13)의 육각 셀 내부에 페놀이 충진되었다면, 상기 하니컴재(13)를 들어올려 냉각한 후 후처리 공정을 수행한다.If the inside of the hexagonal cell of the honeycomb material 13 is filled with phenol through the foaming, the honeycomb material 13 is lifted and cooled to perform a post-treatment process.

상기한 바와같이, 하나의 페놀 폼 보드(11)를 제작하기 위해서, 용액의 혼합 및 가열공정과, 크레인을 이용한 하니컴재(13) 이동 등의 공정이 포함되어야 하므로 그만큼 번거롭고, 특히 경우에 따라 각각의 육각 셀의 내부에 페놀폼(15)이 완전히 충진되지 않을 수 도 있다.As described above, the process of mixing and heating the solution and moving the honeycomb material 13 using a crane must be included in order to manufacture one phenol foam board 11, which is troublesome and troublesome, The phenol foam 15 may not be completely filled in the hexagonal cell of the hexagonal cell.

상기 하니컴재(13)의 내부에 페놀폼(15)이 고른 밀도로 충진되지 않을 경우, 목적하는 단열성과 기계적 강도를 기대할 수 없음은 물론이며, 나아가 페놀폼(15)이 고른 밀도로 충진되더라도 그 만큼 중량이 증가하는 문제점이 있다.If the phenolic foam 15 is not filled in the honeycomb material 13 at an even density, it is not necessarily that the desired heat insulation and mechanical strength can be expected. Further, even if the phenolic foam 15 is filled at a uniform density, There is a problem that the weight increases by a certain amount.

본 발명은 상기 문제점을 해소하고자 창출한 것으로서, 미리 완성되어 있는 부품을 조립하여 구성하는 방식이므로 제작과정이 간단함은 물론, 특히 내부의 하니컴평판체의 내부가 비어 있으므로 밀도가 낮으면서도 단열성능과 내화성이 우수하고, 또한 굴곡탄성률이 좋아 높은 강성이 요구되는 외단열 견축자재로 더욱 적합한 강화 페놀 폼 보드를 제공함에 목적이 있다.The present invention has been made in order to solve the above problems, and it is a method of assembling and composing parts that have been already completed, so that the manufacturing process is simple, and in particular, since the interior of the honeycomb plate body is empty, It is an object of the present invention to provide a reinforced phenol foam board which is excellent in fire resistance and is excellent in flexural modulus and high in rigidity.

상기 목적을 달성하기 위한 본 발명에 따른 강화 페놀 폼 보드는, 일정두께의 플레이트의 형태를 취하고 하니컴 구조를 갖는 하니컴 평판체와; 상기 하니컴 평판체의 일측면 또는 양측면에 접착 고정되는 페놀발포층을 포함하여 구성된 것을 특징으로 한다.According to an aspect of the present invention, there is provided a reinforced phenol foam board comprising: a honeycomb flat plate having a honeycomb structure taking the form of a plate having a predetermined thickness; And a phenolic foam layer adhered and fixed to one side or both sides of the honeycomb flat plate.

또한, 상기 페놀발포층은, 일정두께를 갖는 플레이트의 형태를 취하며, 상기 하니컴 평판체의 표면에 밀착 고정되는 것을 특징으로 한다.Further, the phenol foam layer takes the form of a plate having a predetermined thickness and is fixedly attached to the surface of the honeycomb plate body.

또한, 상기 페놀발포층의 외측면에는, 일정두께의 플레이트 형태를 취하는 하니컴 평판체와, 상기 하니컴 평판체를 커버하는 페놀발포층이 더 구비되는 것을 특징으로 한다.In addition, a honeycomb plate body having a plate thickness of a certain thickness and a phenol foam layer covering the honeycomb plate body are further provided on the outer surface of the phenol foam layer.

아울러, 상기 하니컴평판체는, 합성수지나 금속으로 제작된 것으로서, 두께 방향으로 일정 단면을 갖는 것을 특징으로 한다.In addition, the honeycomb plate body is made of synthetic resin or metal, and has a certain cross section in the thickness direction.

상기와 같이 이루어지는 본 발명의 강화 페놀 폼 보드는, 미리 완성되어 있는 부품을 조립하여 구성하는 방식이므로 제작과정이 간단함은 물론, 특히 내부의 하니컴평판체의 내부가 비어 있으므로 전체 보드의 밀도가 현저히 감소되면서도 단열성능과 내화성이 우수하고, 또한 굴곡탄성률과 압축강도가 우수하여 높은 강성이 요구되는 외단열 건축자재로 더욱 적합하다.The reinforced phenol foam board of the present invention as described above is a method of assembling and composing parts that have been already completed, so that the manufacturing process is simple, and in particular, since the interior of the honeycomb flat plate inside is empty, It is excellent in heat insulation performance and fire resistance, and is more suitable as an outer heat insulating building material which is excellent in flexural modulus and compressive strength and high in rigidity.

이하, 본 발명에 따른 하나의 실시예를 첨부된 도면을 참조하여 보다 상세히 설명하기로 한다.Hereinafter, one embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명의 일 실시예에 따른 강화 페놀 폼 보드(31)의 기본 구성을 설명하기 위하여 도시한 측단면도이다.2 is a side cross-sectional view illustrating a basic structure of a reinforced phenol foam board 31 according to an embodiment of the present invention.

도시한 바와 같이, 본 실시예에 따른 페놀 폼 보드(31)의 기본 구성은, 일정두께의 평판 형태를 취하는 하니컴평판체(33)와, 상기 하니컴평판체(33)의 양측면(도면상 상하면)에 밀착 고정되는 페놀발포층(35)으로 구성된다.As shown in the drawing, the basic configuration of the phenol foam board 31 according to the present embodiment includes a honeycomb flat plate 33 having a flat plate shape with a predetermined thickness, And a phenol foam layer 35 adhered and fixed to the base material.

먼저, 상기 하니컴평판체(33)는, 범용 플라스틱이나 알루미늄으로 제작된 판상 부재로서, 일반적인 하니컴(honeycomb)이 그러하듯이 다수의 육각형의 셀(도 4의 33a)이 밀집된 구성을 갖는다. First, the honeycomb flat plate 33 is a plate-like member made of general-purpose plastic or aluminum, and has a structure in which a plurality of hexagonal cells (33a in FIG. 4) are densely packed as in the case of a general honeycomb.

상기 범용플라스틱을 이루는 재질에는 여러 가지가 포함될 수 있으며 예컨대 폴리프로필렌을 사용할 수도 있다. The material of the general-purpose plastic may include various materials such as polypropylene.

하니컴 구조체의 다른 소재로는 알루미늄도 사용이 가능하며, 폴리프로필렌 하니컴에 비해서 더 우수한 기계적 강도를 나타낼 수 있으나, 단열성능 측면에서는 폴리프로필렌 하니컴구조체가 우수하다.Aluminum can also be used as another material of the honeycomb structure, and it can exhibit more excellent mechanical strength than polypropylene honeycomb, but polypropylene honeycomb structure is superior in terms of heat insulating performance.

하니컴평판체(33)의 두께는 사용 목적에 따라 다르게 제작되며 육각 셀의 크기도 다양하게 변경 가능함은 물론이다.It is needless to say that the thickness of the honeycomb flat plate 33 is made differently according to the purpose of use and the size of the hexagonal cell can be variously changed.

특히 상기 하니컴평판체(33)는, 내부의 육각셀이 비어있는 상태로 상기 페놀발포층(35)에 의해 밀폐되므로 그 내부에 공기층을 유지한다. 상기 공기층에 의해 하니컴평판체(33) 자체의 단열 및 내화 능력이 높아지게 된다. Particularly, the honeycomb flat plate 33 is closed by the phenol foam layer 35 in a state where the hexagonal cell inside is empty, and thus the air layer is retained therein. The air layer allows the honeycomb flat plate 33 itself to have high heat insulation and fire resistance.

상기 하니컴평판체(33)의 양측면에 접착 고정되는 페놀발포층(35)은 일정두께로 형성된 플레이트형 부재로서, 상기 하니컴평판체(33)의 양측면에 밀착 고정되어 있다. 상기 페놀발포층(35)은 그 자체가 내화성이 있고 특히 한 쌍의 페놀발포층(35)이 하니컴평판체(33)를 그 사이에 개재하므로 매우 뛰어난 내화 및 단열성능을 제공한다.The phenolic foam layer 35 adhered and fixed to both sides of the honeycomb flat plate 33 is a plate-like member formed to have a predetermined thickness and is tightly fixed to both sides of the honeycomb flat plate 33. The phenolic foam layer 35 itself is refractory, and in particular, a pair of phenol foam layers 35 interpose the honeycomb plate 33 therebetween, thereby providing excellent fire resistance and heat insulation performance.

상기 페놀발포층(35)은 일반적인 레졸 타입의 페놀수지 100에 대해서 경화촉매로서 파라톨루엔술폰산 5-15 중량부, 발포제로 싸이클로펜탄을 5-10 중량부 혼합하여 고속믹서로 혼련된 슬러리를 가열하여 팽창시키면서 경화된 발포체이다. 이 페놀발포층(35)은 제작하기에 따라서 내화 및 단열성능이 약간씩 차이가 나지만, 본 실시예에서는 25kg/cm3 내지 60kg/cm3 의 밀도를 가지도록 제작할 수 있다. 아울러 상기 페놀발포층(35)의 열전도율은 0.018 내지 0.023W/mk 정도이다.5 to 15 parts by weight of paratoluenesulfonic acid as a curing catalyst and 5-10 parts by weight of cyclopentane as a foaming agent are mixed with 100 parts of the phenol foam layer 35 of a general resole type, and the slurry kneaded with a high speed mixer is heated It is an expanded and cured foam. The phenol foam layer 35 slightly differs in refractory and adiabatic performance according to the production. In this embodiment, however, the phenol foam layer 35 can be manufactured to have a density of 25 kg / cm 3 to 60 kg / cm 3 . In addition, the thermal conductivity of the phenol foam layer 35 is about 0.018 to 0.023 W / mk.

더불어서, 상기 페놀발포층(35)은 폴리실록산 1-5 중량%, 파라톨루엔술폰산 10-18 중량%, 싸이클로펜탄 5-15 중량%, 폴리올 2-6 중량%를 포함하고, 그 독립기포율이 80-97%인 것으로 할 수 있다.In addition, the phenol foam layer 35 comprises 1-5% by weight of polysiloxane, 10-18% by weight of paratoluenesulfonic acid, 5-15% by weight of cyclopentane and 2-6% by weight of polyol, -97%.

상기한 성능을 갖는 페놀발포층(35)의 두께도 필요에 따라 달라짐은 물론이다. 아울러 상기 페놀발포층(35)과 하니컴평판체(33)의 고정은 에폭시 수지나 기타 접착제를 통해 이루어진다. 접착을 통해 만들어진 강화 페놀 폼 보드의 밀도는 15kg/m3 내지 40kg/m3의 낮은 밀도를 갖게 되고, 열전도율은 0.020 W/mK 내지 0.030 W/mK를 갖게 된다. It goes without saying that the thickness of the phenol foam layer 35 having the above-described performance also varies according to need. The phenolic foam layer 35 and the honeycomb plate 33 are fixed by using epoxy resin or other adhesive. The density of the reinforced phenol foam board made through the bond will have a low density of 15 kg / m 3 to 40 kg / m 3 and a thermal conductivity of 0.020 W / mK to 0.030 W / mK.

도 3은 본 발명의 일 실시예에 따른 강화 페놀 폼 보드의 다른 구성을 도시한 도면이다.3 is a view showing another configuration of a reinforced phenol foam board according to an embodiment of the present invention.

도면을 참조하면, 상기 각 페놀발포층(35)의 외측면에 표면재(37)가 부착되어 있음을 알 수 있다. 상기 표면재(37)는 일정두께를 갖는 시트형 부재로서, 페놀발포층(35)을 커버하여 페놀발포층(35)을 보호하며 외부에서 페놀발포층(35)이 보이지 않도록 한다.Referring to the drawing, it can be seen that the surface member 37 is attached to the outer surface of each phenol foam layer 35.
