Description

저수조 내면 라이닝재와 그 제조방법Reservoir inner lining material and manufacturing method

본 발명은 건축물에 부속하는 대형 급수시설로서의 콘크리트제 수수조(受水槽)와 고가수조(高架水槽) 내면에 수밀하게 부착되는 라이닝재 및 그 제조방법(Water Tank Inner Liner and Producing Process Therefor)에 관한 것이다.The present invention relates to a lining material and a manufacturing method thereof (Water Tank Inner Liner and Producing Process Therefor) that are watertightly attached to the inner surface of a concrete water tank and a high water tank as a large water supply facility attached to a building. will be.

아파트, 빌딩 등의 대형 건축물에는 상수원으로부터 보내오는 급수를 저장하였다가 일정한 압력으로 공급하기 위한 급수시설이 설치되어 있다. 이 급수시설 중에서 지하에 매설되는 수수조와 옥상에 설치되는 고가수조는 그 저수용량이 적을 경우에는 섬유강화프라스틱(FRP)으로 만들지만 저수용량이 클 경우에는 콘크리트로 축조된다.Large buildings such as apartments and buildings are equipped with a water supply facility for storing water supplied from a water supply and supplying it at a constant pressure. The water tanks buried underground and the high water tanks installed on the roof are made of fiber-reinforced plastics (FRP) when the water capacity is low, but concrete is constructed when the water capacity is high.

종래에는 이러한 콘크리트제의 저수조 내벽면에 수밀을 유지시키기 위하여 에폭시 수지도료나 유리섬유를 보강재로 한 열경화성 수지를 도포하고 있다. 혹은 두꺼운 연질 플라스틱 시트를 저수조 내면에 플라스틱 스크류를 이용해 못질하여 부착시키는 방법도 있다.Conventionally, in order to maintain the water tightness on the inner wall surface of the concrete water tank, a thermosetting resin made of epoxy resin or glass fiber as a reinforcing material is applied. Alternatively, a thick soft plastic sheet may be nailed to the inner surface of the reservoir using a plastic screw.

그러나, 상기한 도료 또는 수지를 저수조 내벽면에 도포하는 경우에는 영구적인 내장이 되지 못하여 위생성과 내구성면에 있어서 매우 취약한 문제가 있어 왔다. 또 다른 시공구조에서는 5~6m의 콘크리트제 저수조에 1m 폭의 시트를 위에서 아래로 늘어지게 하여 못질하거나 수조의 천정에 못질하게 되면 연질 프라스틱시트의 무게가 무거워 작업의 어려움과 처짐 및 찢어짐 등이 발생하였다.However, when the above-described paint or resin is applied to the inner wall surface of the water tank, there is a problem that is not permanently embedded and very weak in hygiene and durability. In another construction, when the 1m-wide sheet is stretched from top to bottom in a 5 ~ 6m concrete water tank, nailing or nailing to the ceiling of the water tank causes the weight of the soft plastic sheet to be heavy, causing difficulty, sagging, and tearing. It was.

본 발명의 목적은 가벼운 부직포를 이용하여 위생성을 높이면서 내구성 및 방수성이 우수한 재질로 저수조 내면 라이닝재를 구성하기 위한데 있는 것이다.An object of the present invention is to configure the water tank inner lining material with a material having excellent durability and waterproofness while increasing hygiene using a light nonwoven fabric.

본 발명은 상기 목적을 달성하기 위하여, 발수성을 갖는 단섬유 부직포 시트층과, 이 시트층의 형태안정성을 부여할 수 있도록 상기 시트층의 중간에 위치하는 망상 직물층, 그리고 상기 시트층의 일면에 열융착되는 방수 필름층으로 이루어진 라이닝재로 구성한 것이다.In order to achieve the above object, the present invention provides a single-fiber nonwoven fabric sheet layer having water repellency, a mesh fabric layer positioned in the middle of the sheet layer so as to impart morphological stability of the sheet layer, and one surface of the sheet layer. It is composed of a lining material made of a heat-sealed waterproof film layer.

이러한 라이닝재의 제조방법은, 일련의 부직포 섬유 가공공정 중에서 한쌍의 성형기를 각각 통과하는 2장의 섬유상 시트 중간에 망상 직물을 투입하여 니들펀칭기로 서로 교락시켜서 단섬유 부직포 시트를 얻고, 이렇게 얻어진 담섬유 부직포시트의 일면에 방수 필름을 열융착기로 열융착시킨 것이다.In the method of manufacturing such a lining material, a single fiber nonwoven fabric sheet is obtained by inserting mesh fabrics in the middle of two fibrous sheets passing through a pair of molding machines in a series of nonwoven fabric processing processes and intertwining them with a needle punching machine to obtain a single fiber nonwoven fabric sheet. One surface of the sheet is heat-sealed with a heat-sealing film.

본 발명은 상기와 같은 구성에 따라, 가벼운 중량의 부직포가 망상 직물에 의하여 강도가 증가하면서 형태안정성을 가지며, 방수 필름은 방수성을, 단섬유 부직포 시트는 발수성을 각각 가지게 된다.According to the above configuration, the light weight nonwoven fabric has morphological stability while increasing the strength by the mesh fabric, the waterproof film is waterproof, the short-fiber nonwoven sheet has water repellency, respectively.

이하, 본 발명의 실시예를 첨부된 도면에 의하여 설명한다.Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

제1도는 망상 직물(1)이 가운데 삽입된 단섬유 부직포 시트층(2)과 방수 필름층(3)을 갖는 본 발명의 라이닝재(M) 단면을 나타낸다. 방수 필름층(3)은 방수성과 위생성을 높일 수 있는 저밀도 폴리에틸렌(LDPE) 필름으로서 0.3mm 전후가 적합하다. 또, 방수 필름층(3)은 항균성 물질을 적당량 첨가하여 제조된 저밀도 폴리에틸렌 필름(LDPE)를 포함한다. 단섬유 부직포 시트층(2)은 폴리에스터계 단섬유 부직포로, 망상 직물층(1)은 폴리에스터 섬유로 하였다.FIG. 1 shows a cross section of the lining material M of the present invention having a short fiber nonwoven sheet layer 2 and a waterproof film layer 3 with a network fabric 1 interposed therebetween. The waterproof film layer 3 is a low density polyethylene (LDPE) film capable of improving waterproofness and hygiene, and suitable for about 0.3 mm. In addition, the waterproof film layer 3 includes a low density polyethylene film (LDPE) prepared by adding an appropriate amount of an antimicrobial substance. The short fiber nonwoven fabric sheet layer 2 was made of polyester type short fiber nonwoven fabric, and the mesh fabric layer 1 was made of polyester fiber.

단섬유 부직포 시트층(2)의 가운데에 망상 직물(1)을 삽입하는 이유는 인장강도의 보강과 형태안정성 및 물성보강능력을 높이기 위한 것이다. 그것은 상기와 같이 하나의 방수 필름층(3)과 시트층(2)만으로 저수조의 내면에 부착시킬 경우에 라이닝재(M)가 자중에 의하여 가로 또는 세로 방향으로 신장되지 않으면서 일정 두께의 형태를 안정되게 유지할 수 있도록 하기 위한 것이다.The reason why the mesh fabric 1 is inserted in the middle of the short fiber nonwoven sheet layer 2 is to enhance the tensile strength, form stability and physical property reinforcing ability. When the lining material (M) is attached to the inner surface of the water tank with only one waterproof film layer (3) and the sheet layer (2) as described above, the lining material (M) does not extend in the horizontal or vertical direction by its own weight. This is to keep it stable.

본 발명은 일련의 부직포 섬유 가공공정에 따라 망상 직물(1)이 삽입된 단섬유 부직포 시트(2)를 얻고 나서 이 부직포 시트(2)의 일면에 방수 필름(3)을 열접착하여 길이방향으로 연속되는 하나의 라이닝재(M)를 얻게 되는 것으로서, 일련의 부직포 섬유 가공공정을 이하에서 설명한다.The present invention obtains the short-fiber nonwoven fabric sheet 2 into which the mesh fabric 1 is inserted according to a series of nonwoven fabric processing processes, and then heat-bonds the waterproof film 3 to one surface of the nonwoven fabric sheet 2 in the longitudinal direction. As a result of obtaining one continuous lining material M, a series of nonwoven fabric processing steps will be described below.

제2도는 본 발명의 일련의 부직포 섬유 가공공정을 나타낸 것이다.2 shows a series of nonwoven fiber processing processes of the present invention.

제2도에서 21a~25a와 21b~25b는 2장의 섬유상 시트를 별도의 과정을 거쳐 각각 얻기 위한 공정이다. 이 공정은 다음과 같이 이루어진다. 공급기(21a,21b)에서 각각 공급되는 폴리에스터계 단섬유를 베일오프너(22a,22b)에서 각각 개섬(푸는 것)시키고, 개섬된 섬유를 혼합실(23a,23b)에서 각각 혼합시킨다. 혼합된 각각의 섬유는 카딩기(24a,24b)에서 얇은 시트상의 섬유층으로 성형시킨다. 그런 후에 각각 성형기(25a,25b)에 넣고 시트상의 섬유층을 여려겹 겹쳐서 하나의 섬유상 시트(m1,m2)로 성형시킨다. 이와 같이 각각 얻어진 2장의 섬유상 시트(m1,m2)는 직포투입장치(30)로부터 투입되는 폴리에스터계 망상 직물(1)이 중간으로 들어가면서 니들펀칭기(26)에 의하여 2장의 섬유상 시트(m1,m2)와 1장의 망상 직물(1)이 서로 교락되면서 결속(결합)된다. 결속된 부직포 시트는 롤 카렌더(27,127)를 통과하면서 가열가압되고, 건조기(28)를 통과하면서 건조된다.In FIG. 2, 21a to 25a and 21b to 25b are processes for obtaining two fibrous sheets through separate processes. This process is carried out as follows. The polyester short fibers supplied from the feeders 21a and 21b are respectively opened (unwrapped) in the bale openers 22a and 22b, and the opened fibers are mixed in the mixing chambers 23a and 23b, respectively. Each blended fiber is molded into a thin sheet of fibrous layer at carding machines 24a and 24b. Thereafter, the sheets are placed in the molding machines 25a and 25b, respectively, and the sheet-like fibrous layers are piled up several times to form one fibrous sheet m1 and m2. The two fibrous sheets m1 and m2 thus obtained are two fibrous sheets m1 and m2 by the needle punching machine 26 while the polyester mesh cloth 1 fed from the woven feeding device 30 enters the middle. ) And one reticulated fabric (1) are entangled (combined) with each other. The bound nonwoven fabric sheet is heated and pressurized while passing through the roll calenders 27 and 127 and dried while passing through the dryer 28.

그리고, 부직포 시트에 필름투입장치(31)로부터 공급되는 저밀도 폴리에틸렌(LDPE) 필름을 열접착기(32)에 의하여 서로 열접착시키므로서 방수 필름층(3)이 존재하는 라이닝재(M)가 얻어진다.Then, the low-density polyethylene (LDPE) films supplied from the film feeding device 31 to the nonwoven fabric sheet are thermally bonded to each other by the heat sealer 32, thereby obtaining a lining material M in which the waterproof film layer 3 is present. .

이 라이닝재(M)는 약 1m의 폭을 갖는 것으로, 적당한 길이로 절단된 후 저수조의 내면에 못질 등을 통하여 부착된다. 상기 방수 필름층(3)은 방수성 뿐만 아니라 항균성을 가지며, 이러한 성질을 가지는 다른 소재의 필름으로도 적용될 수 있다. 또, 본 발명은 시트층(2)에 발수제를 첨가하여 저수조의 내벽에 형성되는 이슬맺힘 등에 의하여 부직포 시트(2) 내로 수분이 침출되지 않도록 하는 것을 포함한다. 이것은 일련의 부직포 섬유 가공공정 중에서 공급기(21a,21b) 또는 혼합실(23a,23b)에 실리콘계 등의 발수제를 첨가시키는 것에 의하여 달성하는 것이 바람직하다.The lining material (M) has a width of about 1m, is cut to a suitable length, and then attached to the inner surface of the reservoir through nailing. The waterproof film layer 3 is not only waterproof but also antibacterial, and may be applied to a film of another material having such properties. In addition, the present invention includes adding a water repellent agent to the sheet layer 2 so that moisture does not leach into the nonwoven fabric sheet 2 due to dew formation or the like formed on the inner wall of the water storage tank. This is preferably achieved by adding a water repellent such as silicone to the feeders 21a and 21b or the mixing chambers 23a and 23b in a series of nonwoven fabric processing steps.

마지막으로, 본 발명에서는 청구범위의 기술사상을 해치지 않는 범위 내에서 단섬유 부직포 시트층을 직물조직 또는 직물조직에 부직포층이 형성되도록 구성하는 것을 배제하지 않는다.Finally, the present invention does not exclude configuring the short fiber nonwoven sheet layer so that the nonwoven fabric layer is formed on the woven tissue or the woven tissue within a range that does not impair the technical spirit of the claims.

이와 같은 본 발명은 가벼운 부직포를 이용하여 라이닝재로 구성하므로서 시공이 용이하고, 자중이 작고 망상 직물의 삽입에 따른 형태안정성에 의하여 처짐이나 못 등의 결합부에서 찢어짐이 발생하지 않으면서 인장력 및 신장력이 향상되기 때문에 누수되는 일이 없다. 그리고 수지나 도료를 사용하지 않으므로 위생적이면서 내구성이 높아진다. 또, 방수 필름이 항균성 등을 지니고 있어서 인체에 무해하므로 위생적이며, 부직포 시트에 발수제를 첨가하므로써 콘크리트 벽면에서 발생하는 이슬 내지 수분이 부직포 시트 내로 침출되지 않게 하므로서 방수성과 내구성을 더욱 향상시키는 효과가 있다.The present invention is easy to construct as a lining material using a light non-woven fabric, and the tension and elongation force without the occurrence of sagging or tearing at the joints, such as nails due to the shape stability of the insertion of the mesh fabric is small There is no leak because it improves. And since no resin or paint is used, it is hygienic and durable. In addition, since the waterproof film has antibacterial properties and is harmless to the human body, it is hygienic and by adding a water repellent agent to the nonwoven sheet, dew or moisture generated from the concrete wall is not leached into the nonwoven sheet, thereby improving the waterproofness and durability. .
