Description

단열재용 외피재 및 이의 제조방법Cover material for insulation and method for manufacturing the same
본 발명은 단열재와 관련되는 것이되, 특히 단열재의 표면을 구성하는 외피재에 관한 기술이다.The present invention relates to a heat insulating material, and particularly relates to a sheath material constituting a surface of a heat insulating material.
컨테이너선이나 LNG선 등과 같은 대형 선박들은 수많은 격실을 가지게 되고, 수많은 배관들이 설치되어 있다.Large vessels such as container ships and LNG carriers have numerous compartments and numerous pipelines.
격실이나 배관은 마감작업을 위해 단열재로 벽이나 파이프를 덮도록 하거나 감싸도록 한다.The compartment or piping should be covered or enclosed by a wall or pipe with insulation for finishing work.
단열재는 열전달을 차단함으로써 보온, 보냉이 이루어질 수 있도록 하는데, 일반적으로 글라스울이나 미네랄울과 같은 단열성 소재를 주로 많이 사용하게 된다.Insulation materials are used to heat and cool by blocking heat transfer. In general, heat insulation material such as glass wool or mineral wool is used in many cases.
익히 알려진 바와 같이 글라스울이나 미네랄울은 소정 두께가 되도록 적층구조를 형성하여 판상체나 곡면체로 성형하여 선체의 벽 외면에 부착시키거나 배관을 감싸도록 장착된다.As is well known, glass wool or mineral wool is formed to have a laminated structure having a predetermined thickness and is formed into a plate or a curved body to be attached to the outer surface of the hull wall or to surround the pipe.
글라스울이나 미네랄울은 적당한 두께를 갖도록 함으로써 기본적인 강도와 단열특성을 가지게 되나, 외력이 작용하는 경우 쉽게 수축될 수 있다는 성질을 가진다. 따라서 단열재로서의 형상 유지 특성을 고려하여 고밀도로 글라스울이나 미네랄울을 적층하기도 한다.The glass wool or mineral wool has a proper thickness so that it has basic strength and heat insulation characteristics, but has a property that it can be easily shrunk when an external force acts. Therefore, glass wool or mineral wool may be laminated at a high density in consideration of shape retaining properties as a heat insulating material.
한편, 단열재의 표면 강도 및 접촉에 의한 손상 그리고 외관을 고려하여 글라스울이나 미네랄울 표면에 외피재를 부착하게 된다.On the other hand, in consideration of the surface strength of the heat insulating material, the damage due to the contact, and the appearance, the outer cladding material is attached to the surface of the glass wool or mineral wool.
일반적으로 단열재의 외피재는 소정 두께를 갖는 알루미늄 시트를 사용하는 경우가 많은데, 접착제를 이용하여 알루미늄 시트를 부착하게 된다.Generally, an aluminum sheet having a predetermined thickness is often used as a cover material of a heat insulating material, and an aluminum sheet is attached using an adhesive.
한편, 알루미늄 시트 자체만으로는 쉽게 찢어질 수 있기 때문에 알루미늄 시트의 일면에 일정한 패턴으로 직조되는 글라스크로스(glass cross)를 부착하여 사용하고 있다.On the other hand, since the aluminum sheet itself can easily be torn, a glass cross woven in a certain pattern is attached to one surface of the aluminum sheet.
알루미늄 시트에 부착되는 글라스크로스는 가로재와 세로재가 직교되면서 엮여서 형성되는 시트와 같은 것으로, 일정한 패턴을 이루게 됨에 따라 알루미늄 시트와 결합되면 알루미늄 시트의 외면에 일정한 패턴의 요철이 형성된다.The glass cloth adhered to the aluminum sheet is like a sheet formed by laminating crosswise and longitudinal members orthogonal to each other. When the aluminum sheet is combined with the aluminum sheet, a certain pattern of irregularities is formed on the outer surface of the aluminum sheet.
그리고 알루미늄 시트에 일정한 패턴을 갖는 글라스크로스를 부착하게 되면, 외피재가 접히는 경우 가로재 혹은 세로재의 방향으로 쉽게 접히게 되어 복원이 잘 이루어지지 않게 되고, 시공 후에도 접혔던 라인이 남아 있어 외관을 해치게 되는 문제점이 있었고, 일정한 패턴을 갖는 글라스크로스로 인해 흡음 및 차음 특성이 떨어진다는 문제점도 있었다.When the glass cloth having a certain pattern is attached to the aluminum sheet, the outer cladding material is easily folded in the direction of the horizontal or vertical material when folded, so that the restoration is not performed well and the folded lines remain after the construction, And there was a problem that the sound absorption and sound insulation characteristics were deteriorated due to the glass cloth having a certain pattern.
또한, 알루미늄 시트에 부착된 글라스크로스 자체에 의한 열흡수 능력이 떨어지므로 알루미늄 시트 외표면의 온도가 높다는 문제점도 있었다.Further, since the glass cloth itself attached to the aluminum sheet itself has low heat absorbing ability, there is a problem that the temperature of the outer surface of the aluminum sheet is high.

도시된 바와 같이 본 발명에 의한 단열재용 외피재(100)는 표피재(110)와 장섬유시트(120)로 이루어지며, 단열재의 외면에 부착되어 사용되는 것이다.As shown in the figure, the outer cover material 100 according to the present invention is composed of a skin material 110 and a long fiber sheet 120, and is attached to the outer surface of the heat insulating material.
소정 두께를 갖는 단열소재는 글라스울이나 미네랄울과 같은 것이 사용될 수 있으며, 사각 판상과 같은 형태로 단열소재를 적층한 후 그 외면에 외피재를 부착하게 된다.As the heat insulating material having a predetermined thickness, glass wool or mineral wool may be used, and a heat insulating material is laminated in the form of a quadrangular plate, and then a sheath material is attached to the outer surface of the heat insulating material.
단열재용 외피재(100)를 이루는 표피재(110)는 알루미늄 호일이나 알루미늄 증착 필름과 같이 비투습성을 갖는 필름 형상을 갖는 것을 사용하도록 한다. The skin material 110 constituting the heat insulating shell material 100 is preferably made of a film having a moisture impermeable property such as an aluminum foil or an aluminum evaporated film.
표피재(110)로 알루미늄 호일이나 알루미늄 증착 필름은 하나의 예에 불과한 것이며, 그 외에도 에틸렌비닐알콜, 폴리비닐알콜, 산화규소, 산화 알루미늄, 나노클레이 코팅 및 유,무기 복합재질을 포함하는 필름 형상인 것들이 사용될 수 있다.The aluminum foil or the aluminum evaporated film as an example of the skin material 110 is merely an example. In addition, a film shape including ethylene vinyl alcohol, polyvinyl alcohol, silicon oxide, aluminum oxide, nano clay coating, May be used.
표피재(110)의 일면에 접착수단을 이용하여 장섬유시트(120)가 부착되며, 장섬유시트(120)는 소정길이로 절단된 장섬유를 불규칙하게 적층하여 소정 두께로 형성한 것을 의미한다.The long fiber sheet 120 is attached to one surface of the skin material 110 by the adhesive means and the long fiber sheet 120 means that the long fibers cut to a predetermined length are irregularly laminated to have a predetermined thickness .
여기에서, 장섬유시트(120)는 촙스트랜드 매트(Chopped Strand Mat), 이글라스 매트(E-Glass Mat), 탄소섬유 중 어느 하나를 사용할 수 있고, 얇은 매트와 같은 것이다.Here, the long fiber sheet 120 may be any one of chopped strand mat, E-glass mat, and carbon fiber, and is a thin mat.
특히, 촙스트랜드 매트는 이글라스 조성을 갖는 유리섬유를 대략 50mm 정도의 길이로 절단하여 얇고 편평한 매트로 만든 것을 말하는데, 절단된 장섬유를 접착제를 이용하여 결합한 것이다. 촙스트랜드 매트의 제조시 사용되는 접착제는 불포화 폴리에스터수지를 사용한다. 촙스트랜드 매트는 수지함침 속도가 빠르다는 장점이 있고 곡면성형이 용이하다는 특징이 있다.In particular, the quilted strand mat is made of a thin and flat mat by cutting a glass fiber having an Eagle's composition length to a length of about 50 mm, which is obtained by bonding the cut long fibers with an adhesive. 불 Unsaturated polyester resin is used as the adhesive used in the production of the strand mat. 촙 Strand mat has the advantage of fast resin impregnation speed and is easy to mold surface.
본 발명의 실시예에서는 장섬유시트로 촙스트랜드 매트를 사용하는 것으로 한다.In the embodiment of the present invention, a long strand mat is used as the long strand mat.
장섬유시트(120)는 유리섬유와 같은 장섬유를 소정의 길이로 절단한 후 소정 두께가 되도록 불규칙한 배열로 배치하여 결합하여 만들게 됨으로써 내부에 수많은 공극이 형성된다는 장점이 있다. 장유섬시트(120) 내부에 형성되는 공극들로 인해 쿠션 특성이 매우 우수하게 되며, 장섬유가 불규칙한 배열을 이루게 됨으로써 어떠한 방향으로 접히게 되더라도 복원성이 우수하게 된다는 장점이 생긴다.The long fiber sheet 120 is formed by cutting long fibers such as glass fibers into a predetermined length and arranging the fibers in an irregular arrangement so as to have a predetermined thickness, thereby forming numerous voids therein. The pores formed in the large oil island sheet 120 have a very excellent cushioning property and the long fibers are arranged irregularly so that the stability is improved even if they are folded in any direction.
그리고 이러한 장섬유시트(120)가 알루미늄 호일과 같은 표피재(110)에 결합되면 무수한 공극의 존재로 인해 흡음 및 차음 특성을 향상시킬 수 있다는 장점도 가진다.Also, when the long fiber sheet 120 is bonded to the skin material 110 such as aluminum foil, there is an advantage that the sound absorption and sound insulation characteristics can be improved due to the presence of innumerable voids.
바람직하게 장섬유시트(120)는 그 두께가 200 ~ 1000㎛ 인 것으로 하며, 필요에 맞게 언급한 범위 내에서 적당한 두께의 장섬유시트를 사용하면 된다.Preferably, the long fiber sheet 120 has a thickness of 200 to 1000 占 퐉, and a suitable length of the long fiber sheet may be used within the range mentioned above.
불규칙한 배열로 이루어지는 장섬유시트(120)는 동일한 두께를 갖는 글라스크로스에 비교하여 복원성이 매우 우수하며, 공극도 많이 생기므로 뛰어난 장점이 있고, 예를 들어 두께가 400㎛ 인 글라스크로스를 사용하는 경우보다 두께 400㎛ 인 장섬유시트를 사용하는 것이 보다 우수한 특성을 나타낸다.The long fiber sheet 120 having an irregular arrangement has an excellent advantage in that the glass cloth having the same thickness has excellent stability and a lot of voids as compared with the glass cloth having the same thickness. For example, when a glass cloth having a thickness of 400 m is used The use of a long fiber sheet having a thickness of 400 占 퐉 is more preferable.
산업적으로 널리 사용되는 글라스크로스의 두께는 100 ~ 400㎛ 이며, 본 발명에서의 장섬유시트(120)는 200 ~ 1000㎛ 의 두께를 갖는 것을 사용하는 것이 바람직하다. The thickness of the glass cloth widely used in the industry is 100 to 400 탆, and the long fiber sheet 120 in the present invention preferably has a thickness of 200 to 1000 탆.
장섬유시트(120)의 두께를 1000㎛ 초과하는 두께를 적용하는 것은 단열재에 부착시, 특히 곡면으로 이루어지는 단열재인 경우 형상을 잡는데 어려움이 발생하기 때문에 200 ~ 1000㎛ 두께를 사용하도록 한다.If the thickness of the long fiber sheet 120 is more than 1000 占 퐉, the thickness of the long fiber sheet 120 should be 200 to 1000 占 퐉.
그리고 알루미늄 호일과 같은 표피재(110)에 장섬유시트(120)를 부착함에 있어서는 접착수단을 사용하게 되는데, 이때 사용되는 접착수단으로는 접착제, 점착제, 레진과 같은 것들이 사용될 수 있다. 대표적으로 접착수단은 핫멜트 종류를 사용하도록 하는데 PE(폴리에틸렌) 필름을 녹여서 접착수단으로 사용할 수 있다.In order to attach the long fiber sheet 120 to the skin material 110 such as an aluminum foil, an adhesive means is used. As the adhesive means used in this case, an adhesive, an adhesive, and a resin may be used. Typically, the adhesive means is made of a hot-melt type, and a PE (polyethylene) film can be melted and used as an adhesive means.
접착수단은 표피재(110)에 도포하도록 하거나 장섬유시트(120)에 도포하여 상호간 결합이 되게 맞붙여서 접합이 되도록 할 수 있는데, 본 실시예의 경우 자동화에 적합하도록 하고자 핫멜트의 하나인 난연성의 PE필름을 접착수단으로 사용하도록 하며, 표피재와 장섬유시트를 공급할 때 표피재와 장섬유시트 사이로 PE필름을 함께 공급되게 하면서 열과 압력을 작용시켜서 녹은 PE필름에 의해 표피재와 장섬유시트가 일체로 결합이 이루어지도록 한다.The bonding means may be applied to the skin material 110 or may be applied to the long fiber sheet 120 so that they are bonded together to be joined together. In this embodiment, in order to be suitable for automation, a flame-retardant PE The film is used as a bonding means, and when the skin material and the long fiber sheet are supplied, the PE film is supplied together with the skin material and the long fiber sheet, and the skin material and the long fiber sheet are integrally .
접착수단으로 핫멜트를 사용함이 바람직한데, 핫멜트에도 다양한 종류가 있으며, 본 실시예의 경우 PE필름 형태로 제공되는 핫멜트를 사용하며, 특히 난연성이 부여된 PE필름을 사용하도록 하는 것이 보다 적합하다.It is preferable to use hot melt as the adhesive means. There are various kinds of hot melts. In this embodiment, hot melts provided in the form of PE film are used, and it is more preferable to use a PE film imparted with flame retardancy.
표피재(110)에 장섬유시트(120)를 부착시킬 때에는 금형이나 지그를 이용하여 적당한 가압력을 작용시키면서 접착수단에 의해 결합이 이루어지게 하는데, 바람직하게는 지그나 금형에 적당한 열이 발생되게 하여 접착수단이 열에 의해 보다 빠르게 경화되면서 접합이 원활이 이루어질 수 있도록 한다.When the long fibrous sheet 120 is attached to the skin material 110, a proper pressing force is applied by using a mold or a jig, and bonding is performed by the bonding means. Preferably, heat is generated in the jig or the mold The bonding means is cured more quickly by heat so that the bonding can be smoothly performed.
보다 바람직하게, 표피재(110)에 장섬유(120)를 부착시킬 때 금형이나 지그를 이용한 외압을 부여함에 따라 장섬유시트(120)에 일정한 요철이 형성되도록 할 수 있다. 이를 위해 금형이나 지그에는 일정한 배열로 돌출되는 가압돌기가 형성되도록 하여 장섬유시트(120)가 상면이 되도록 한 상태에서 금형이나 지그를 누르게 되면, 가압돌기에 맞닿는 부분은 타 부위보다 깊게 눌러져 오목한 홈(121)을 형성시키게 되고, 가압돌기에 의한 가압에 의해 보다 강력한 접합이 이루어질 수 있다.More preferably, when the long fibers 120 are adhered to the skin material 110, a certain unevenness can be formed on the long fiber sheet 120 by applying an external pressure using a mold or a jig. When the mold or the jig presses the mold or jig in a state in which the long fiber sheet 120 is in an upper surface by forming a pressing protrusion protruding in a constant arrangement, the portion abutting the press protrusion is pressed deeper than the other portion, (121) is formed, and stronger bonding can be achieved by pressing by the pressing projection.
본 발명에 의한 단열재용 외피재를 구성하는 장섬유시트에 일정한 요철이 형성되게 하면, 실제 단열재용 외피재를 단열재에 부착시켜 사용하는 경우 장섬유시트에 인위적으로 만들어진 홈 부위는 빈 공간으로 남게 됨으로써 단열특성 및 흡음, 차음 등의 특성을 더욱 좋게 할 수 있도록 한다는 효과가 있다.When a certain concavity and convexity is formed on the long fiber sheet constituting the heat insulating shell material according to the present invention, when the actual heat insulating material is adhered to the heat insulating material, the groove portion artificially formed on the long fiber sheet is left as an empty space The heat insulating property, the sound absorption property, and the sound insulation property can be improved.
한편, 첨부되는 도 5는 본 발명에 의한 단열재용 외피재와 기존의 단열재용 외피재의 비교 사진으로서, 도 5의 에이(a)는 기존의 단열재용 외피재이고, 비(b)는 본 발명에 의한 단열재용 외피재의 외면 사진이다.5 (a) and 5 (b) are cross-sectional photographs of a conventional heat insulating cladding material and a conventional heat insulating cladding material according to the present invention. Fig. 3 is a photograph of the outer surface of a jacket material for a heat insulating material according to the present invention.
기존의 단열재용 외피재는 알루미늄 호일에 글라스크로스를 결합한 것이므로, 외피재의 외면에 글라스크로스의 일정한 패턴 무늬가 그대로 표출된다. 반면에 본 발명의 단열재용 외피재의 경우 알루미늄 호일에 불규칙한 장섬유가 배열된 장섬유시트가 부착되므로 표피재 외면으로 불규칙한 장섬유시트의 배열형식이 그대로 표출되는 것이다.Since the conventional outer cover material for insulation has a glass cloth bonded to the aluminum foil, a certain pattern pattern of the glass cloth is directly exposed on the outer surface of the outer cover material. On the other hand, in the case of the heat insulating cladding material of the present invention, since the long fiber sheet with irregular long fibers is attached to the aluminum foil, the arrangement form of the irregular long fiber sheet is directly expressed on the outer surface of the skin material.
즉, 도 5를 통해 확인할 수 있는 바와 같이 본 발명의 단열재용 외피재의 경우 장섬유시트 자체를 구성하는 장섬유들의 불규칙한 배열이 그대로 표출되므로 기존과는 다른 새롭고 보다 미려한 미감을 제공할 수 있다. That is, as can be seen from FIG. 5, in the case of the heat insulating shell material of the present invention, since the irregular arrangement of the long fibers constituting the long fiber sheet itself is expressed as it is, new and more beautiful aesthetic can be provided.
다음으로 본 발명의 또 다른 사상인 단열재용 외피재의 제조방법에 대해 설명하도록 한다.Next, a method for manufacturing a casing material for a heat insulating material, which is another aspect of the present invention, will be described.
본 발명에 의한 단열재용 외피재의 제조방법에서는 알루미늄 호일, 알루미늄 증착 필름과 같은 비투습성인 필름 형상의 표피재에 장섬유가 불규칙하게 적층되면서 형성되는 장섬유시트를 부착하도록 하되, 상기 표피재와 장섬유시트 사이에 접착수단을 두고서 열과 압력을 가함으로써 상기 표피재와 장섬유시트가 결합이 이루어지고, 상기 접착수단이 장섬유시트에 함침되면서 상기 표피재와 견고한 결합력을 형성하도록 한다.In the method for producing a casing material for a heat insulating material according to the present invention, a long fiber sheet formed by irregularly stacking long fibers in a non-breathable film-like skin material such as an aluminum foil or an aluminum evaporated film is adhered, The skin material and the long fiber sheet are combined by applying heat and pressure with the adhesive means between the fiber sheets so that the adhesive means is impregnated into the long fiber sheet to form a firm binding force with the skin material.
여기서 접착수단은 접착제, 점착제, 레진 등 다양한 공지의 접착력을 제공하는 것들이 사용될 수 있으며, 이러한 접착수단은 수작업이나 자동화를 통해 장섬유시트나 알루미늄 호일에 도포 내지 코팅될 수 있다.Here, the adhesive means may be any of those providing various known adhesive strengths such as adhesives, pressure-sensitive adhesives, and resins. Such adhesive means may be coated or coated on sheets of long fiber or aluminum foil by hand or automation.
본 발명의 바람직한 실시예에서는 접착수단으로 접착필름을 사용하도록 하는데, 특히 PE필름을 사용하도록 하며, 이러한 접착필름을 사용하게 되면 외피재 생산을 자동화로 구성할 수 있고, 난연성을 갖는 PE필름을 사용할 수 있다.In the preferred embodiment of the present invention, an adhesive film is used as a bonding means. In particular, a PE film is used. When such an adhesive film is used, it is possible to automate the production of a covering material and use a PE film having flame retardancy .
보다 구체적으로는, 표피재(110), PE필름(130), 장섬유시트(120)를 준비하되, 자동화가 가능하도록 각각은 롤상으로 감겨진 상태에서 인장력에 의해 풀리면서 롤러 형상의 성형금형(200)에서 합체가 이루어지도록 한다.More specifically, the skin material 110, the PE film 130, and the long fiber sheet 120 are prepared, and each of them is rolled up in a rolled state so as to be automated, 200).
표피재(110)는 알루미늄 호일이나 알루미늄 증착 필름과 같은 비투습성인 것이며, 장섬유시트(120)는 장섬유가 불규칙하게 적층되어 소정 두께를 갖도록 성형되는 시트상의 소재이다. 장섬유시트(120)는 소정길이로 절단된 장섬유가 불규칙하게 적층되어 형성되므로 내부에 무수한 공극을 가지게 되는 특성이 있다. 그리고 장섬유시트의 두께는 200 ~ 1000㎛ 범위인 것을 사용하도록 한다.The skin material 110 is non-moisture-permeable such as aluminum foil or an aluminum evaporated film, and the long fiber sheet 120 is a sheet-like material that is formed so that long fibers are irregularly stacked to have a predetermined thickness. The long fiber sheet 120 is formed by irregularly stacking long fibers cut to a predetermined length, so that the long fiber sheet 120 has innumerable voids therein. And the thickness of the long fiber sheet is in the range of 200 to 1000 mu m.
표피재(110)와 장섬유시트(120)를 일체가 되게 결합하기 위해 PE필름(130)이 사용되는데, PE필름(130)은 얇은 필름 형태를 이루고 있고, 열이 작용되면 녹게 되는 성질이 있다.A PE film 130 is used to integrally join the skin material 110 and the long fiber sheet 120. The PE film 130 has a thin film form and is melted when heat is applied .
표피재(110), PE필름(130), 장섬유시트(120)가 성형금형(200)으로 진입되어 열과 압력의 작용하에서 결합이 이루어지는데, 이때 열에 의해 PE필름(130)이 녹게되고 녹은 PE필름(130)은 장섬유시트(120)에 함침됨과 동시에 표피재(110)와도 결합을 이루게 되고, 불규한 표면을 갖고 또한 내부에 공극을 갖는 장섬유시트(120)로 PE필름이 함침됨에 따라 뛰어난 결합구조를 형성하게 된다.The PE film 130 and the long fiber sheet 120 enter the molding die 200 and are bonded under the action of heat and pressure. At this time, the PE film 130 is melted by the heat, The film 130 is impregnated into the long fiber sheet 120 and is also bonded to the skin material 110. The PE film is impregnated with the long fiber sheet 120 having an uneven surface and having voids therein And an excellent bonding structure is formed.
접착제로서 본 실시예에서는 PE필름을 사용하도록 하나, PE필름은 핫멜트의 하나일 뿐이며, 단열재가 사용되는 장소의 특성에 따라 핫멜트 중 적당한 것을 선택 사용할 수 있고, PE필름은 난연성을 갖는 것이 사용될 수도 있다.In this embodiment, a PE film is used as the adhesive, but the PE film is only one of the hot melts. Depending on the characteristics of the place where the heat insulating material is used, a suitable one among the hot melts can be selectively used. .
본 발명에 의한 단열재용 외피재는 단열재의 제조시에 사용될 수 있는 기술이다.The covering material for a heat insulating material according to the present invention is a technique that can be used in the production of a heat insulating material.
