본 발명은 알루미늄 하니컴 판넬용 접착필름 및 그 제조방법에 관한 것이다. 보다 구체적으로는, 건축소재인 하니컴심재를 표면재와 부착시키는데 사용되는 접착필름 및 그 제조방법에 관한 것이다.The present invention relates to an adhesive film for aluminum honeycomb panel and a method of manufacturing the same. More specifically, the present invention relates to an adhesive film used to attach a honeycomb core material, which is a building material, to a surface material, and a manufacturing method thereof.

알루미늄복합판넬(aluminum composite panel)은 알루미늄 판 두겹사이로 PE 혹은 난연PE로 구성된 심재가 접착성 필름등에 의해 구성되는 고층건물의 내·외장 장식용으로 사용되는 건축소재를 말한다. Aluminum composite panel refers to a building material used for interior and exterior decoration of high-rise buildings in which core material composed of PE or flame retardant PE is composed of adhesive film between two layers of aluminum plates.

고층건물일수록 상부 층의 무게균형을 위해 가벼운 소재의 장식소재를 선호하는 것이 일반적이며 특히 알루미늄 소재의 화려한 외관으로 인해 시장에서 소재의 활용도가 높아지고 있는 추세이다.Higher buildings are generally favoring lightweight decorative materials to balance the weight of the upper floors, especially due to the brilliant appearance of aluminum materials.

그러나 최근에는 보다 가볍고 화재 발생시 외관의 변형이 일어나지 않는(일반 판넬의 경우 중간층의 PE 혹은 난연PE 심재가 화재시 연소하면서 외관변형이 일어남) 소재의 수요가 늘어나고 있으며 그 대안으로 제시된 제품이 알루미늄 하니컴(honey comb) 판넬이다. Recently, however, there is a growing demand for materials that are lighter and that do not change appearance in the event of fire (in the case of ordinary panels, PE or flame retardant PE core materials burn in the event of fire), and the alternative product is aluminum honeycomb ( honey comb) panel.

알루미늄 하니컴 판넬은 복합판넬과 같이 샌드위치 구조로서 알루미늄 2매 사이에 하니컴코어(honeycomb) 소재를 고온 압착시킨 제품으로 현존 외벽 판넬 중 최고의 경량과 강성을 동시에 지닌 그리고 단위 중량비 중 최성능의 평탄성과 강도 를 지닌 제품으로 각광을 받고 있다. Aluminum honeycomb panel is a sandwich structure like composite panel. It is a product that honeycomb core material is pressed at high temperature between two sheets of aluminum. It has the best light weight and rigidity among the existing exterior wall panels and has the highest flatness and strength in unit weight ratio. It has been in the spotlight for its products.

그러나, 하니컴 구조의 특성상 표면재와의 접착이 용이치 않으며 폴리우레탄등의 접착제를 사용함으로 인해 연속작업이 불가능하고 생산성이 저하되어 이로 인해 원할한 생산여건이 확보되지 못하는 문제점이 있다.However, due to the characteristics of the honeycomb structure, the adhesion with the surface material is not easy, and continuous operation is impossible due to the use of an adhesive such as polyurethane, and productivity is lowered, thereby preventing a smooth production condition.

또한, 기존의 알루미늄 복합판넬용 접착성 필름의 경우 PE 및 난연PE와 알루미늄 소재와의 접착력은 좋으나 하니컴 구조의 경우 상하 알루미늄판과 하니컴의 접착구조상 상대적인 접착면적의 한계로 접착력을 확보할 수 없어 근본적으로 사용이 불가능한 상태이다.In addition, in the case of the conventional adhesive film for aluminum composite panel, the adhesive strength between PE, flame retardant PE and aluminum material is good, but in the case of honeycomb structure, the adhesive force cannot be secured due to the limitation of relative adhesive area due to the bonding structure between the upper and lower aluminum plates and honeycomb. It is not available.

특히, 하니컴 심재의 경우 얇고 길어서 기존의 접착성 필름의 두께인 30-50㎛로는 접착력을 유지하기가 어렵고 또한 기존 필름의 물성 개선 없이 단순히 두께만 가지고도 하니컴심재와 알루미늄판 사이의 접착력을 유지할 수가 없는 문제점이 있다.In particular, the honeycomb core material is thin and long, so it is difficult to maintain the adhesive strength with the thickness of the conventional adhesive film 30-50㎛, and it is impossible to maintain the adhesive force between the honeycomb core material and the aluminum plate simply by the thickness without improving the properties of the existing film. There is no problem.

본 발명은 상기와 같은 문제점을 감안하여 안출된 것으로서, 하니컴심재와 표면재의 결합력을 증대시키고 특히 건축소재로 각광을 받고 있는 하니컴판넬을 연속적으로 생산하는 것이 가능하도록 하는 알루미늄 하니컴 판넬용 접착필름 및 그 제조방법을 제공하는데 그 목적이 있다. The present invention has been made in view of the above problems, the adhesive film for aluminum honeycomb panel to increase the bonding strength of the honeycomb core material and the surface material, and in particular to be able to continuously produce a honeycomb panel that is spotlighted as a building material and its The purpose is to provide a manufacturing method.

이하, 첨부된 도면을 참조하여 본 발명의 바람직한 실시예에 따른 알루미늄 하니컴 판넬용 접착필름 및 제조방법을 상세히 설명하기로 한다.Hereinafter, with reference to the accompanying drawings will be described in detail the adhesive film and manufacturing method for the aluminum honeycomb panel according to an embodiment of the present invention.

도 1에서, 알루미늄판(101)은 표면재로서 고층건물 등의 내·외장 장식용으로 사용되는 판상의 건축소재로 알루미늄 소재가 사용된다. 또한, 하니컴심재(102)는 알루미늄 단일 소재로 된 얇고 가벼운 벌집(honey comb) 모양의 건축소재이다.In FIG. 1, the aluminum plate 101 is an aluminum material used as a plate-like building material used for interior and exterior decoration, such as a high-rise building as a surface material. In addition, the honeycomb core material 102 is a thin and light honeycomb-shaped building material made of a single aluminum material.

본 발명의 실시예에 따른 접착필름(100)은 알루미늄판(101)과 하니컴심재(102) 사이에 위치하여 알루미늄판(101)과 하니컴심재(102)를 서로 결합시키는 기능을 수행한다.The adhesive film 100 according to the embodiment of the present invention is positioned between the aluminum plate 101 and the honeycomb core material 102 to perform the function of coupling the aluminum plate 101 and the honeycomb core material 102 to each other.

이를 위해 접착필름(100)의 각 면은 알루미늄판(101)과 하니컴심재(102)에 각각 부착되는데, 알루미늄판(101)과 접착하는 면과 하니컴심재(102)와 접착하는 면의 접착력과 물성이 서로 다르게 조성되어 있다. 특히 하니컴심재(102)와 접착하는 면의 용융지수(melt index)가 알루미늄판(101)과 접착하는 면의 용융지수에 비해 더 높기 때문에 접착층이 하니컴심재(102)의 빈공간(103)으로 함침되어 접착면적이 증가하게 되고 결과적으로 접착력이 증가되는 것이다.To this end, each surface of the adhesive film 100 is attached to the aluminum plate 101 and the honeycomb core material 102, respectively, the adhesive strength and physical properties of the surface to be bonded to the aluminum plate 101 and the honeycomb core material 102 This is different composition. In particular, the adhesive layer is impregnated into the void space 103 of the honeycomb core material 102 because the melt index of the surface that is in contact with the honeycomb core material 102 is higher than the melt index of the surface that is in contact with the aluminum plate 101. As a result, the adhesion area increases, and consequently, the adhesion force increases.

도 2에서, 본 발명의 실시예에 따른 접착필름(100)은 알루미늄판(101)과 대면하여 접착되는 제 1 접착층(110)과 하니컴심재(102)와 대면하여 접착되는 제 2 접착층(120)을 포함한다.In FIG. 2, the adhesive film 100 according to the embodiment of the present invention has the first adhesive layer 110 and the second adhesive layer 120 bonded to face the honeycomb core material 102 to face the aluminum plate 101. It includes.

이때, 제 1 접착층(110)과 제 2 접착층(120)의 용융지수는 서로 다르며, 바람직하게는 제 2 접착층(120)의 용융지수가 제 1 접착층(110)의 용융지수보다 더 높다.In this case, the melt index of the first adhesive layer 110 and the second adhesive layer 120 are different from each other, preferably, the melt index of the second adhesive layer 120 is higher than the melt index of the first adhesive layer 110.

용융지수(melt index)란 수지(플라스틱)의 물성을 나타내는 대표적인 factor로써, 소정의 MI측정기를 사용하여 측정되는 것이 일반적이며, 용융지수의 단위로는 10분동안 흘러나온 시료의 무게, 즉 g/10min를 사용한다.Melt index is a representative factor indicating the physical properties of the resin (plastic), it is generally measured by using a predetermined MI meter, the unit of the melt index is the weight of the sample flowed out for 10 minutes, that is, g / Use 10min.

본 실시예에서는 제 1 접착층(110)의 용융지수는 1~4로, 제 2 접착층(120)의 용융지수는 5~20으로 설정되었다. 더 바람직하게는 제 1 접착층(110)의 용융지수는 3으로, 제 2 접착층(120)의 용융지수는 12로 설정하는 것이 좋다. 이렇게 서로 다른 용융지수를 갖는 접착층을 형성하는 구체적인 방법에 대해서는 후술하도록 한다.In this embodiment, the melt index of the first adhesive layer 110 is set to 1-4, and the melt index of the second adhesive layer 120 is set to 5-20. More preferably, the melt index of the first adhesive layer 110 is set to 3, and the melt index of the second adhesive layer 120 is set to 12. A specific method of forming the adhesive layers having different melt indexes will be described later.

하니컴심재(102)와 접촉되는 제 2 접착층(120)은 제 1 접착층(110)에 비해 용융지수가 크므로 동일한 온도 조건에서 양 부재(101)(102)를 결합시키는 공정을 수행하게 되면 용융지수가 큰 제 2 접착층(120)은 하니컴심재(102)의 빈공간(103)으로 함침되며 접착된다. 따라서 종래 접착방법에 비해 접착면적이 증가하게 되고 접착력 또한 우수하게 되는 것이다.Since the second adhesive layer 120 in contact with the honeycomb core material 102 has a larger melt index than the first adhesive layer 110, the melt index is performed when the two members 101 and 102 are bonded under the same temperature condition. The large second adhesive layer 120 is impregnated into the empty space 103 of the honeycomb core material 102 and bonded. Therefore, the adhesion area is increased and the adhesion is also excellent compared to the conventional bonding method.

다음으로, 도 3을 참조하며 본 발명의 실시예에 따른 접착필름의 제조방법에 대해 설명하기로 한다.Next, referring to Figure 3 will be described with respect to the manufacturing method of the adhesive film according to an embodiment of the present invention.

도 3을 참조하면, 본 발명의 실시예에 따른 접착필름의 제조방법은 크게 그라프토머(graftomer) 준비 단계(S310), 컴파운딩(compounding) 단계(S320), 및 필름성형 단계(S330)로 나눌 수 있다. 개략적으로, 그라프토머(graftomer) 준비 단계(S310)에서 제조 공정상 기초가 되는 물질을 준비하고, 컴파운딩(compounding) 단계(S320)에서 상기 준비된 물질에 첨가물을 가하여 제 1 접착층(110, 도 2참조) 및 제 2 접착층(120, 도 2참조)으로 사용될 레진(resin)을 제조한 후, 필름성형 단계(S330)에서 각 접착층(110)(120)을 서로 부착시켜 2-layer 접착필름을 만들게 된다.Referring to FIG. 3, a method of manufacturing an adhesive film according to an embodiment of the present invention is largely divided into a graftomer preparing step (S310), a compounding (compounding) step (S320), and a film forming step (S330). Can be. In general, in the graftomer preparation step (S310), a material that is a basis for a manufacturing process is prepared, and in the compounding step (S320), an additive is added to the prepared material to form the first adhesive layer 110 (FIG. 2). Resin) to be used as the second adhesive layer (120, see FIG. 2), and then, in the film forming step (S330), the adhesive layers 110 and 120 are attached to each other to form a 2-layer adhesive film. do.

이를 구체적으로 살펴보면, 먼저 그라프토머(graftomer) 준비 단계(S310)는 제조 공정 상의 기재(base material)로 사용되는 극성 그라프토머(graftomer)를 제 조하기 위해 비극성 폴리에틸렌(polyethylene, 이하 PE라 함)을 개질(reforming)시키는 단계이다.Specifically, first, a graftomer preparation step (S310) is a non-polar polyethylene (hereinafter referred to as PE) to manufacture a polar graftomer (graftomer) used as a base material (base material) in the manufacturing process This is a step of reforming.

즉, 용융지수 10 ~ 20, 밀도 0.950 ~ 0.960인 PE에 과산화물(peroxide)을 첨가하여 에틸렌 결합을 끊어 라디칼(radical)을 생성하고, 여기에 극성기 도입을 위한 그라프팅제(grafting agent)로 MAH(maleic anhydride)를 에틸렌 결합에 도입시켜 극성의 성질을 갖는 그라프토머(graftomer)를 제조하게 된다.That is, by adding peroxide to PE having a melt index of 10 to 20 and a density of 0.950 to 0.960, radicals are formed by breaking ethylene bonds, and MAH (maleic) as a grafting agent for introducing a polar group thereto. Anhydride) is introduced into the ethylene bond to produce a graftomer having polar properties.

다시 말해, 압출기(twin extruder)의 고온·고압의 조건에 의한 중합을 통해 그라프팅제인 MAH를 PE와 결합시키는 것인데, PE가 압출기 내의 고온·고압 하에서 과산화물(반응개시제)에 의해 극성 성분들과의 그라프팅이 가능한 모노머(monomer) 라디칼(radical)을 생성하게 되며, 이때 첨가된 MAH의 극성기와 결합하여 그라프토머(graftomer)가 생산되는 것이다.In other words, MAH, which is a grafting agent, is combined with PE through polymerization under high temperature and high pressure conditions of a twin extruder, and PE is mixed with polar components by peroxide (reacting initiator) under high temperature and high pressure in the extruder. A grafting monomer radical is generated, and a graftomer is produced by combining with the polar group of the added MAH.

이때 초기의 비극성 PE로 고밀도폴리에틸렌(HDPE, high density polyethylene)이 사용될 수 있으며, MAH 및 과산화물 외에도 산화방지제가 첨가될 수 있다.At this time, high density polyethylene (HDPE) may be used as the initial nonpolar PE, and antioxidants may be added in addition to MAH and peroxide.

또한 실험에 사용된 기기는 twin extruder 75MM(L/D=24:1)이고, 가공온도는 210~230℃이다.In addition, the instrument used in the experiment is a twin extruder 75MM (L / D = 24: 1), the processing temperature is 210 ~ 230 ℃.

컴파운딩(compounding) 단계(S320)는 상기 단계에서 준비된 그라프토머(graftomer)에 저밀도폴리에틸렌(LDPE, low density polyethylene), 선형저밀도폴리에틸렌(LLDPE, linear low density polyethlene), 고밀도폴리에틸렌(HDPE, high density polyethylene), 에틸렌비닐아세테이트(EVA, ethylene vinyl acetate), 에틸렌프로필렌러버(EPR, ethylene propylene rubber), 부타디엔러버(BR, butadiene rubber), 스틸렌에틸렌부타디엔스틸렌(SEBS, styrene ethylene butadiene styrene) 등의 폴리머(접착성 수지조성물)를 첨가하여 각기 다른 물성(예컨대, 용융지수)을 갖는 제 1 접착층(110) 및 제 2 접착층(120)을 각각 형성시키는 단계이다.Compounding step (S320) is a low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE, high density polyethylene) in the graftomer prepared in the step ), Polymers such as ethylene vinyl acetate (EVA, ethylene vinyl acetate), ethylene propylene rubber (EPR, ethylene propylene rubber), butadiene rubber (BR, butadiene rubber), styrene ethylene butadiene styrene (SEBS) It is a step of forming a first adhesive layer 110 and a second adhesive layer 120 having different physical properties (eg, melt index) by adding a resin composition).

상술하였듯이, 제 1 접착층(110)과 제 2 접착층(120)의 용융지수는 서로 다르다. 이를 위해 컴파운딩 단계(S320)는 알루미늄판(101, 도 2참조)과 대면하여 접착되는 제 1 접착층(110)이 형성되도록 S310 단계에서 제조된 그라프토머에 접착성 수지조성물을 첨가하여 압출 제립하고, 이어서 하니컴심재(102, 도 2참조)와 대면하여 접착되는 제 2 접착층(120)이 형성되도록 상기 S310 단계의 그라프토머에 접착성 수지조성물을 첨가하되 제 1 접착층(110)보다 높은 용융지수를 갖는 제 2 접착른 조성으로 상기 접착성 수지조성물을 첨가하여 압출 제립하는 것이 가능하다.As described above, the melt indexes of the first adhesive layer 110 and the second adhesive layer 120 are different from each other. To this end, the compounding step (S320) is extruded and granulated by adding an adhesive resin composition to the graft copolymer prepared in step S310 so that the first adhesive layer 110 is formed to face the aluminum plate 101 (see FIG. 2). Then, an adhesive resin composition is added to the graphitizer of step S310 to form a second adhesive layer 120 to be faced with the honeycomb core material 102 (see FIG. 2), but has a higher melt index than the first adhesive layer 110. It is possible to carry out extrusion granulation by adding the adhesive resin composition with the second adhesive composition having.

또한 추가적인 폴리머(접착성 수지조성물)을 첨가함에 있어서 제 1 접착층(110)의 용융지수는 1~4로, 제 2 접착층(120)의 용융지수는 5~20이 되도록 조성과 비율을 적절히 조절하여 첨가하는 것이 바람직하다.In addition, in the addition of an additional polymer (adhesive resin composition), the melt index of the first adhesive layer 110 is 1-4, and the melt index of the second adhesive layer 120 is 5-20, so that the composition and ratio are appropriately adjusted. It is preferable to add.

표 1은 각 접착층(110)(120)을 형성하기 위해 그라프토머(graftomer)에 첨가되는 폴리머(접착성 수지조성물)의 종류 및 비율을 나타낸 것이다.Table 1 shows the types and ratios of polymers (adhesive resin compositions) added to the graftomer to form the adhesive layers 110 and 120.

표 2에서와 같이 알루미늄판(101)과 접촉되는 제 1 접착층(110)에 비해 하니컴심재(102)와 접촉되는 제 2 접착층(120)의 MI(용융지수)가 더 큰 것을 알 수 있다.As shown in Table 2, the MI (melt index) of the second adhesive layer 120 in contact with the honeycomb core material 102 is greater than that of the first adhesive layer 110 in contact with the aluminum plate 101.

마지막으로 필름성형 단계(S330)는 상기 과정을 통해 형성된 제 1 접착층(110)과 제 2 접착층(120)을 상하로 적층시켜 부착시키는 단계이다.Finally, the film forming step S330 is a step of laminating the first adhesive layer 110 and the second adhesive layer 120 formed by the above process up and down.

필름성형 단계(S330)는 2층 필름 성형기를 이용하여 제 1 접착층(110)과 제 2 접착층(120)을 부착시키며, 이때 제 1 접착층(110)은 접착필름(100)의 전체 두께의 40~60% 정도로 설계하고, 제 2 접착층(120)은 접착필름(100)의 전체 두께의 60~40% 정도로 설계하여 저온에서도 높은 용융지수를 갖는 제 2 접착층(120)이 하니컴심재(102)의 빈공간에 잘 함침되고 강한 접착력을 보유할 수 있도록 하는 것이 좋다.Film forming step (S330) is attached to the first adhesive layer 110 and the second adhesive layer 120 using a two-layer film molding machine, wherein the first adhesive layer 110 is 40 ~ of the entire thickness of the adhesive film 100 60% design, the second adhesive layer 120 is designed to 60 ~ 40% of the total thickness of the adhesive film 100, the second adhesive layer 120 having a high melt index even at low temperature is the hollow of the honeycomb core material 102 It is good to be well impregnated into space and to have strong adhesion.

또한 접착필름(100)의 두께는 100~500μm 인 것이 바람직하다.In addition, the thickness of the adhesive film 100 is preferably 100 ~ 500μm.

상기 과정을 거치면 도 2에서와 같이 2층 구조(2-layer)의 접착필름(100)이 형성되며, 상기 접착필름(100)은 용융지수가 다른 제 1 접착층(110)과 제 2 접착층(120)을 포함하고, 특히 하니컴심재(102)와 대면하는 제 2 접착층(120)이 제 1 접착층(110)에 비해 용융지수가 높기 때문에 하니컴심재(102)와 접촉하는 면은 하니컴심재(102)의 빈공간으로 투입되고 공간상의 벽면에 접착되어 우수한 접착능력을 발휘하게 되는 것이다.Through the above process, as shown in FIG. 2, a two-layer adhesive film 100 is formed, and the adhesive film 100 has a first adhesive layer 110 and a second adhesive layer 120 having different melt indices. And the honeycomb core 102 is in contact with the honeycomb core 102 because the second adhesive layer 120 facing the honeycomb core 102 has a higher melt index than the first adhesive layer 110. It is put into the empty space and adhered to the wall in the space to exhibit excellent adhesion ability.

본 실시예에서는 2층 구조의 접착필름(100)에 대하여 설명하였으나, 2층 이상의 다층구조(multi-layer)를 갖는 필름(film) 내지는 시트(sheet)로 응용할 수도 있다.In the present embodiment, the adhesive film 100 having a two-layer structure has been described, but it may be applied to a film or a sheet having a multi-layer of two or more layers.

도 4는 본 발명의 실시예에 따른 접착필름(100)을 사용하여 건축소재로 사용되는 알루미늄하니컴판넬(400)을 연속적으로 생산하는 방법을 설명하기 위한 도면이다.4 is a view for explaining a method for continuously producing an aluminum honeycomb panel 400 used as a building material using the adhesive film 100 according to an embodiment of the present invention.

도 4에서, 알루미늄판(101), 접착필름(100)은 알루미늄판롤(420)과 필름롤(410)에 각각 감겨있고, 하니컴심재(102)는 두 개의 히팅롤(430) 사이를 일정한 온도에서 소정의 압력을 받으며 통과하게 되는 구조이다.In FIG. 4, the aluminum plate 101 and the adhesive film 100 are wound on the aluminum plate roll 420 and the film roll 410, respectively, and the honeycomb core material 102 is formed at a constant temperature between the two heating rolls 430. It is a structure that passes under a predetermined pressure.

본 발명의 실시예에 따른 접착필름(100)은 용융지수가 다른 2개의 접착층으로 되어 있고, 각 접착층은 알루미늄판(101)과 접촉하는 층(제 1 접착층)과 하니컴심재(102)와 접촉하는 층(제 2 접착층)으로 구분되기 때문에 필름롤(410)에는 그 방향을 고려하여 감겨있게 되는 것은 당연한 결과이다.Adhesive film 100 according to an embodiment of the present invention is composed of two adhesive layers having different melt index, each adhesive layer is in contact with the aluminum plate 101 (first adhesive layer) and the honeycomb core material 102 Since it is divided into layers (second adhesive layers), it is a natural result that the film roll 410 is wound in consideration of its direction.

알루미늄판(101)과 접착필름(100)은 보조롤(440)을 통해 히팅롤(430)쪽으로 유도되며, 보조롤(440)을 지나면서 접착필름(100)의 제 1 접착층(110)이 알루미늄 판(101)과 대면한다. 이어서 하니컴심재(102)가 히팅롤(430) 사이를 통과하면서 제 2 접착층(120)이 하니컴심재(102)와 대면하게 되고, 히팅롤(430)의 온도와 압력으로 인해 각 접착층(110)(120)이 알루미늄판(101)과 하니컴심재(102)에 각각 접착되는 것이다. The aluminum plate 101 and the adhesive film 100 are guided to the heating roll 430 through the auxiliary roll 440, and the first adhesive layer 110 of the adhesive film 100 is made of aluminum while passing through the auxiliary roll 440. It faces the board 101. Subsequently, as the honeycomb core material 102 passes between the heating rolls 430, the second adhesive layer 120 faces the honeycomb core material 102, and each adhesive layer 110 is formed due to the temperature and pressure of the heating roll 430. 120 is bonded to the aluminum plate 101 and the honeycomb core material 102, respectively.

이때 제 2 접착층(120)은 제 1 접착층(110)에 비해 용융지수가 크므로 동일한 온도 조건에서 용융지수가 큰 제 2 접착층(120)은 하니컴심재(102)의 빈공간으로 함침되며, 연속적으로 하니컴판넬(400)을 생산할 수 있게 된다.In this case, since the second adhesive layer 120 has a larger melt index than the first adhesive layer 110, the second adhesive layer 120 having a large melt index under the same temperature condition is impregnated into an empty space of the honeycomb core material 102. The honeycomb panel 400 can be produced.

이상에서 본 발명의 바람직한 실시예에 대하여 설명하였으나 본 발명은 상술한 특정의 실시예에 한정되지 아니한다. 즉, 본 발명이 속하는 기술분야에서 통상의 지식을 가지는 자라면 첨부된 특허청구범위의 사상 및 범주를 일탈함이 없이 본 발명에 대한 다수의 변경 및 수정이 가능하며, 그러한 모든 적절한 변경 및 수정의 균등물들도 본 발명의 범위에 속하는 것으로 간주되어야 할 것이다.Although preferred embodiments of the present invention have been described above, the present invention is not limited to the above-described specific embodiments. That is, those skilled in the art to which the present invention pertains can make many changes and modifications to the present invention without departing from the spirit and scope of the appended claims, and all such appropriate changes and modifications are possible. Equivalents should be considered to be within the scope of the present invention.

이상에서 설명한 바와 같이, 본 발명에 따른 알루미늄 하니컴 판넬용 접착필름 및 제조방법에 의하면, 표면재와 하니컴심재를 결합시키는 접착필름에 있어서 상대적으로 좁은 접착 표면적을 가지는 하니컴심재와 접촉되는 면의 물성을 표면재와 접촉되는 면과 다르게 형성하였기 때문에 접착필름의 일부가 하니컴심재의 빈공간으로 함침되며 접착이 이루어져서 우수한 접착력을 확보할 수 있는 효과가 있다. 또한, 소정의 시트형태로 구성된 접착필름을 사용하였기 때문에 건축자재로 사용되는 하니컴판넬을 생산하는 경우 이를 연속적으로 생산할 수 있어 생산성이 향상되며, 나아가 친환경 및 건물의 고층화에 따른 경량화가 대세인 추후 건축소재 시장 개발과 보조를 같이하여 시장을 선도할 수 있는 장점이 있다.As described above, according to the adhesive film and manufacturing method for the aluminum honeycomb panel according to the present invention, the physical properties of the surface in contact with the honeycomb core material having a relatively narrow adhesive surface area in the adhesive film bonding the surface material and the honeycomb core material Since it is formed differently from the surface in contact with the part of the adhesive film is impregnated into the empty space of the honeycomb core material and the adhesion is made there is an effect that can secure excellent adhesion. In addition, since an adhesive film composed of a predetermined sheet form is used, when producing a honeycomb panel used as a building material, it can be continuously produced, thereby improving productivity, and furthermore, a building material that is light in weight due to eco-friendly and high-rise building. It has the advantage of leading the market by keeping pace with market development.
