수축 복원 기능을 갖는 복합단열패널{Composite Insulation Panel with Shrinkage Restoration}Composite Insulation Panel with Shrinkage Restoration

본 발명은 LNG 운반선 등과 같이 대상물을 초저온 상태로 저장하기 위해 저장탱크를 단열시키기 위한 목적으로 단열벽체 사이의 틈에 끼워지는 수축 복원 기능을 갖는 복합단열패널에 관한 기술이다.The present invention relates to a composite insulation panel having a shrinkage restoration function that is fitted into a gap between insulating walls for the purpose of insulating a storage tank to store an object in a cryogenic state, such as an LNG carrier.

청정 연료로 LNG에 대한 수요가 증가됨에 따라 LNG 운반선의 중요성이 부각되고 있으며, LNG 운반선은 가스상의 연료를 초저온으로 액화하여 저장한 채 운송하도록 함에 따라 높은 기술력이 요구된다.As the demand for LNG as a clean fuel increases, the importance of LNG carriers is being highlighted.

저장탱크에 초저온 상태로 LNG를 저장하기 위해서는 저장탱크에 대한 단열이 무엇보다도 중요하며, 단열벽체를 구성할 때 이웃하는 단열벽체 사이의 틈을 메워주기 위한 목적으로 소정규격의 끼움재를 설치하게 된다. In order to store LNG in a cryogenic state in the storage tank, insulation of the storage tank is of utmost importance, and when constructing the insulation wall, a fitting material of a predetermined standard is installed for the purpose of filling the gap between adjacent insulation walls. .

끼움재 역시 단열특성을 갖는 것이어야하며, 끼움재는 단열벽체의 좁은 틈으로 설치되어야 하는 바, 작업성이 좋아야 하고 설치 후에는 밀폐력을 제공해야 한다는 상반적인 요구특성을 가지고 있다.The fitting material should also have heat insulation properties, and the fitting material should be installed through a narrow gap in the insulating wall, so workability should be good and sealing power should be provided after installation.

종래기술에서는 메인단열판(1)과 완충단열판(2)이 유리섬유천(3)을 매개로 상호 결합되며, 메인단열판과 완충단열판의 외측면은 염화비닐시트(4)가 부착되고, 메인단열판과 완충단열판의 모서리를 따라 비닐테이프가 부착되는 구조로 이루어지고, 단열벽체를 이루는 우레탄판넬(5)들 사이 공간으로 단열재를 끼워넣도록 한다.In the prior art, the main insulation plate (1) and the buffer insulation plate (2) are coupled to each other via the fiberglass cloth (3), and the outer surface of the main insulation plate and the buffer insulation plate is attached with a vinyl chloride sheet (4), and the main insulation plate and the It has a structure in which a vinyl tape is attached along the edge of the buffer insulation plate, and the insulation material is inserted into the space between the urethane panels 5 constituting the insulation wall.

하지만 종래기술의 경우 단열벽체 사이의 틈으로 넣을 때 부분적으로 단열재를 가압하여 수축시킨 후 밀어넣도록 하므로 작업성이 매우 나쁘고, 메인단열판과 완충단열판 각각은 하나의 단체로 이루어지고, 최소 하나 이상의 일단면이 개방되어있으므로 단열특성이 떨어진다는 문제점도 있었다.However, in the case of the prior art, workability is very poor because the insulating material is partially compressed and compressed when it is inserted into the gap between the insulating walls, and the workability is very poor. Since the surface is open, there is also a problem in that the thermal insulation properties are poor.

복수개의 단위패널(200a)을 폭 방향으로 적층하여 제1단열패널(100)과 같은 폭을 갖도록 제작함으로써 제2단열패널(200)이 제작되며, 인접한 단위패널(200a)들 사이에는 소정의 분리막(201)이 결합되도록 한다.The second insulating panel 200 is manufactured by stacking a plurality of unit panels 200a in the width direction to have the same width as the first insulating panel 100, and a predetermined separator is formed between adjacent unit panels 200a. (201) is combined.

폭 방향으로 상하 가장자리에 배치되는 단위패널(200a)을 외측단위패널(210)이라 부르며, 그 사이로 배치되는 단위패널을 내측단위패널(220)이라 부르도록 한다. 내측단위패널(220)은 최소 2개 이상 복수개로 이루어지도록 한다.The unit panel 200a disposed at the upper and lower edges in the width direction is called the outer unit panel 210 , and the unit panel disposed therebetween is called the inner unit panel 220 . The inner unit panel 220 is made of at least two or more.

보다 구체적으로 본 실시예의 경우 총 5개의 단위패널(200a)과 4개의 분리막(201)이 결합되어 제2단열패널(200)이 형성되도록 하는데, 도 3에 도시된 바와 같이 하측으로부터 단위패널들은 제1단위패널(210-1), 제2단위패널(220-2), 제3단위패널(220-3), 제4단위패널(220-4), 제5단위패널(210-5)이라 부르도록 한다. 특히 제1단위패널(210-1)과 제5단위패널(210-5)은 동일한 폭을 갖거나 다른 폭을 갖게 되며, 제2단위패널(220-2), 제3단위패널(220-3), 제4단위패널(220-4)은 동일한 폭을 갖게 된다. 제1단위패널(210-1)과 제5단위패널(210-5)이 외측단위패널(210)에 해당되고, 제2단위패널(220-2), 제3단위패널(220-3), 제4단위패널(220-4)은 내측단위패널(220)에 해당된다.More specifically, in the present embodiment, a total of five unit panels 200a and four separation membranes 201 are combined to form a second heat insulating panel 200, and as shown in FIG. 3, the unit panels from the lower side are The first unit panel 210-1, the second unit panel 220-2, the third unit panel 220-3, the fourth unit panel 220-4, and the fifth unit panel 210-5 are called. let it be In particular, the first unit panel 210-1 and the fifth unit panel 210-5 have the same width or different widths, and the second unit panel 220-2 and the third unit panel 220-3 ), the fourth unit panel 220-4 has the same width. The first unit panel 210-1 and the fifth unit panel 210-5 correspond to the outer unit panel 210, the second unit panel 220-2, the third unit panel 220-3, The fourth unit panel 220 - 4 corresponds to the inner unit panel 220 .

따라서, 제1단위패널(210-1)의 치수는 두께(T2), 폭(W2-1), 길이(L2)가 되고, 제2단위패널(220-2)의 치수는 두께(T2), 폭(W2-2), 길이(L2)가 되고, 제3단위패널(220-3)의 치수는 두께(T2), 폭(W2-3), 길이(L2)가 되고, 제4단위패널(220-4)의 치수는 두께(T2), 폭(W2-4), 길이(L2)가 되고, 제5단위패널(210-5)의 치수는 두께(T2), 폭(W2-5), 길이(L2)가 된다.Accordingly, the dimensions of the first unit panel 210-1 are the thickness T2, the width W2-1, and the length L2, and the dimensions of the second unit panel 220-2 are the thickness T2, The width W2-2 and the length L2 are the dimensions of the third unit panel 220-3 are the thickness T2, the width W2-3, and the length L2, and the fourth unit panel 220-3 is 220-4) is the thickness (T2), width (W2-4), and length (L2), and the dimensions of the fifth unit panel 210-5 are thickness (T2), width (W2-5), It becomes the length L2.

그리고 분리막(201)은 비통기성의 소재가 적합하며, 종이재나 합성수지재가 사용될 수 있고, 분리막(201)의 두께(TS)는 얇은 필름 정도가 되도록 한다.In addition, non-breathable material is suitable for the separator 201 , and a paper material or a synthetic resin material may be used, and the thickness TS of the separator 201 is made to be about a thin film.

따라서 제1단열패널(100)의 폭(W1)과 제2단열패널(200)의 폭(W2)의 관계는 다음과 같다고 할 수 있다.Therefore, the relationship between the width W1 of the first heat insulating panel 100 and the width W2 of the second heat insulating panel 200 is as follows.

W1=W2=(W2-1+W2-2+W2-3+W2-4+W2-5+4TS)W1=W2=(W2-1+W2-2+W2-3+W2-4+W2-5+4TS)

바람직하게 제2단열패널(200)의 가장자리를 이루는 제1단위패널(210-1)과 제5단위패널(210-5)의 폭은 제2단위패널(220-2), 제3단위패널(220-3), 제4단위패널(220-4)의 폭 보다 작도록 한다.Preferably, the width of the first unit panel 210-1 and the fifth unit panel 210-5 forming the edge of the second heat insulating panel 200 is the second unit panel 220-2, the third unit panel ( 220-3) to be smaller than the width of the fourth unit panel 220-4.

즉, W2-1≠W2-5 〈 W2-2=W2-3=W2-4 의 관계를 갖는다.That is, it has a relationship of W2-1≠W2-5 < W2-2=W2-3=W2-4.

한편, 제1단열패널(100)과 제2단열패널(200)은 폭 방향으로 서로 결합되는데, 이를 위해 코어글라스크로스(300)를 이용하여 제1단열패널(100)과 제2단열패널(200)을 접합되도록 한다. 즉, 코어글라스크로스(300)의 양면에 접착제를 도포하여 일면에 제1단열패널(100)을 부착하고 타면에 제2단열패널(200)을 부착시켜서 전체적으로 일체가 되도록 한다.On the other hand, the first insulating panel 100 and the second insulating panel 200 are coupled to each other in the width direction, for this, the first insulating panel 100 and the second insulating panel 200 using the core glass cloth 300 ) to be joined. That is, an adhesive is applied to both sides of the core glass cross 300 to attach the first heat insulating panel 100 to one side and the second heat insulating panel 200 to the other side so that the whole is integrated.

제1단열패널(100)과 제2단열패널(200) 사이에 위치되는 코어글라스크로스(300)는 접착제가 굳으면서 제1단열패널(100) 및 제2단열패널(200)과 결합되고 접착제가 마르게 되면 빳빳하게 굳어져 코어 역할을 하게 된다.The core glass cross 300 positioned between the first heat insulating panel 100 and the second heat insulating panel 200 is combined with the first heat insulating panel 100 and the second heat insulating panel 200 while the adhesive is hardened, and the adhesive is formed. When it dries, it hardens and acts as a core.

여기서 코어글라스크로스(300)는 글라스화이버를 가로 및 세로 방향으로 배치하여 격자를 이루도록 한 얇은 유리섬유천을 의미한다.Here, the core glass cross 300 means a thin glass fiber cloth in which glass fibers are arranged in the horizontal and vertical directions to form a grid.

한편, 코어글라스크로스(300)와 마주보게 제1단열패널(100)의 외면에는 제1서피스글라스크로스(400)가 부착되며, 제2단열패널(200)의 외면에는 제2서피스글라스크로스(500)가 부착된다.On the other hand, the first surface glass cloth 400 is attached to the outer surface of the first insulating panel 100 to face the core glass cross 300 , and the second surface glass cloth 500 is attached to the outer surface of the second insulating panel 200 . ) is attached.

즉, 제1서피스글라스크로스(400)의 일면에 접착제를 도포하여 제1단열패널(100)과 접합되도록 하고, 제2서피스글라스크로스(500)의 일면에도 접착제를 도포하여 제2단열패널(200)과 접합되도록 한다.That is, an adhesive is applied to one side of the first surface glass cross 400 to be bonded to the first insulating panel 100 , and an adhesive is also applied to one side of the second surface glass cross 500 to make the second insulating panel 200 . ) to be combined with

특히, 제1서피스글라스크로스(400)와 제2서피스글라스크로스(500)는 그 일면 또는 양면에 러버 코팅이 얇게 형성될 수 있다. 코어글라스크로스(300)의 경우는 그 외면에 러버 코팅이 되지 않도록 함이 바람직하나 제1서피스글라스크로스(400)와 제2서피스글라스크로스(500)의 최소 어느 일면에는 얇게 러버 코팅을 실시하도록 한다.In particular, the first surface glass cross 400 and the second surface glass cross 500 may have a thin rubber coating on one or both surfaces thereof. In the case of the core glass cross 300, it is preferable not to apply a rubber coating on the outer surface, but at least one surface of the first surface glass cross 400 and the second surface glass cross 500 is coated with a thin rubber. .

러버 코팅되지 않는 코어글라스크로스(300)는 양호한 통기성을 갖게 되나, 러버 코팅이 이루어지는 제1서피스글라스크로스(400)와 제2서피스글라스크로스(500)의 경우는 상대적으로 낮은 통기성을 갖게 되는데, 이는 본 발명의 수축 복원 기능을 갖는 복합단열패널의 시공시에 전체 두께를 일시적으로 줄이고자 진공흡입시에 제각각의 역할을 하게 된다.The core glass cross 300 that is not coated with rubber has good air permeability, but the first surface glass cross 400 and the second surface glass cross 500 with rubber coating have relatively low air permeability, which In order to temporarily reduce the overall thickness during the construction of the composite insulation panel having a shrinkage restoration function of the present invention, each plays a role during vacuum suction.

다시 말해서 제1단열패널(100)과 제2단열패널(200) 사이에 부착된 코어글라스크로스(300)는 양호한 통기성을 갖게 되는데, 제1단열패널(100)에 흡입노즐을 끼워서 진공흡입을 하게 되면 내부 공기가 배출되면서 두께가 얇아지게 된다. 이때 통기성이 우수한 코어글라스크로스(300)를 통해서 제2단열패널(200)의 공기가 통과되어 진공펌프로 흡입될 수 있도록 한다.In other words, the core glass cross 300 attached between the first heat insulating panel 100 and the second heat insulating panel 200 has good air permeability. As the internal air is discharged, the thickness becomes thinner. At this time, the air of the second heat insulating panel 200 passes through the core glass cross 300 having excellent air permeability so that it can be sucked into the vacuum pump.

반면에 제1단열패널(100)과 제2단열패널(200)의 외면을 감싸는 제1서피스글라스크로스(400)와 제2서피스글라스크로스(500)는 코어글라스크로스(300)에 비해 지극히 낮은 통기성을 갖기 때문에 진공흡입시 외기 유입을 차단하여 빠르게 제1단열패널(100) 및 제2단열패널(200)의 두께가 감소될 수 있도록 기능하게 된다.On the other hand, the first surface glass cloth 400 and the second surface glass cloth 500 surrounding the outer surfaces of the first insulation panel 100 and the second insulation panel 200 have extremely low air permeability compared to the core glass cloth 300 . It functions so that the thickness of the first insulating panel 100 and the second insulating panel 200 can be reduced quickly by blocking the inflow of external air during vacuum suction.

제1서피스글라스크로스(400)와 제2서피스글라스크로스(500)에 적용되는 러브 코팅의 정도에 따라 통기성이 달라질 수 있으며, 필요에 맞게 일면 또는 양면으로 러버 코팅을 하거나 코팅의 두께를 달리하는 방법 등으로 통기도를 조절함이 바람직하다.Breathability may vary depending on the degree of rub coating applied to the first surface glass cross 400 and the second surface glass cross 500, and a method of rubber coating on one or both sides or varying the thickness of the coating as needed It is preferable to adjust the air permeability with the like.

제1단열패널(100)과 제2단열패널(200)이 일체화된 상태에서 메인밀봉테이프(600)를 이용하여 4면에 대한 밀봉이 이루어지도록 한다. 메인밀봉테이프(600)는 ㄷ 자 형상이 되어 제1단열패널(100) 및 제2단열패널(200)의 가장자리에 접합되는데, 제1면(610)은 제1서피스글라스크로스(400)의 가장자리를 덮게 되고, 제2면(620)은 제2서피스글라스크로스(500)의 가장자리를 덮게 되고, 제3면(630)은 제1단열패널(100)과 제2단열패널(200)의 두께면을 덮게 된다.In a state in which the first heat insulating panel 100 and the second heat insulating panel 200 are integrated, the four sides are sealed using the main sealing tape 600 . The main sealing tape 600 has a U-shape and is bonded to the edges of the first insulating panel 100 and the second insulating panel 200 , and the first surface 610 is the edge of the first surface glass cross 400 . is covered, the second surface 620 covers the edge of the second surface glass cross 500 , and the third surface 630 is the thickness surface of the first insulation panel 100 and the second insulation panel 200 . will cover

그리고 제1단열패널(100)과 제2단열패널(200)의 각 모서리에서 코너부에 대한 추가적인 밀봉을 위해 코너밀봉테이프(700)가 부착된다. 구체적으로 코너밀봉테이프(700)는 모서리에 인접된 메인밀봉테이프(600)를 덮으면서 결합되는데, 코너밀봉테이프(700)는 정사각형 또는 직사각형의 형상을 이루되, 상하 센터라인을 따라 상단과 하단에 절개라인(710)이 소정깊이까지 형성되어 있으며, 각 모서리에 결합될 때 제1상단편(701)에 제2상단편(702)이 겹쳐지게 부착되고, 제1하단편(703)과 제2하단편(704)도 서로 겹쳐지게 결합됨으로써 코너부에 대한 보강이 이루어지게 한다.In addition, a corner sealing tape 700 is attached to each corner of the first heat insulating panel 100 and the second heat insulating panel 200 to further seal the corner portions. Specifically, the corner sealing tape 700 is coupled while covering the main sealing tape 600 adjacent to the corner, and the corner sealing tape 700 has a square or rectangular shape, and is located at the top and bottom along the upper and lower center lines. The cut-out line 710 is formed to a predetermined depth, and when coupled to each corner, the second upper end piece 702 is attached to overlap the first upper end piece 701, and the first lower end piece 703 and the second The lower end 704 is also coupled to overlap each other, so that the corner portion is reinforced.

이상 설명한 바와 같은 본 발명에 따른 수축 복원 기능을 갖는 복합단열패널은 LNG 선박과 같이 초저온 상태로 저장이 요구되는 유체의 저장탱크에 대한 단열벽체(P)를 구성할 때 도 5와 같이 단열벽체(P)간 형성되는 틈에 끼워져 틈을 통한 열손실이 발생되는 것을 최소화할 수 있도록 하며, 동시에 온도나 습도 변화에 따른 단열벽체의 수축 팽창에 대한 완충작용을 할 수 있도록 기능하게 된다.As described above, the composite insulation panel having a shrinkage restoration function according to the present invention is a thermal insulation wall (P) as shown in FIG. It is inserted into the gap formed between P) to minimize heat loss through the gap, and at the same time, it functions to act as a buffer against the shrinkage and expansion of the insulating wall according to temperature or humidity changes.

특히 제1단열패널 및 제2단열패널의 외면에 부착되는 제1서피스글라스크로스와 제2서피스글라스크로스는 글라스화이버를 가로세로 직조한 유리섬유천에 러브 코팅이 이루어지도록 한 것이므로 무수히 많은 격자를 가지게 되고 이러한 격자라인이 단열패널의 표면과 접촉되어 무수한 씰링라인을 형성함에 따라 밀폐 특성을 더욱 높일 수 있게 된다.In particular, the first surface glass cloth and the second surface glass cloth attached to the outer surfaces of the first and second insulation panels are made to have a love coating on a glass fiber cloth woven horizontally and vertically with glass fibers, so they have countless grids. As these grid lines come into contact with the surface of the insulation panel to form countless sealing lines, the sealing characteristics can be further improved.

그리고 제2단열패널은 복수개의 단위패널의 결합으로 이루어지고 이웃하는 단위패널 사이에는 보호막이 삽입되어 있는 구조인 바, 다단 단열특성이 제공될 수 있고, 가장자리의 단위패널의 폭은 내부의 단위패널의 폭 보다 작게 하여 보호막을 하나 더 둘 수 있도록 함으로써 보다 우수한 단열 특성을 제공할 수 있게 된다.In addition, the second insulating panel is made of a combination of a plurality of unit panels and has a structure in which a protective film is inserted between adjacent unit panels, so that multi-stage thermal insulation properties can be provided, and the width of the unit panel at the edge is the inner unit panel. By making it smaller than the width of , it is possible to provide one more protective film, thereby providing better thermal insulation properties.

본 발명은 초저온 유체를 저장하거나 운송하는 플랜트 또는 선박용 단열재로 사용될 수 있다.The present invention can be used as a thermal insulation material for plants or ships that store or transport cryogenic fluids.
