Description
도 1은 종래의 기능성 적층 원단의 단면을 나타내는 모식도,1 is a schematic diagram showing a cross section of a conventional functional laminated fabric,

도 3은 본 발명에 따른 투습 방습 방수포의 제조 방법을 설명하기 위한 흐름도.3 is a flow chart for explaining a method for manufacturing a moisture-permeable moisture-proof tarpaulin according to the present invention.
본 발명은 발포 투습 방습 방수포와 그 제조 방법에 관한 것으로, 특히 폴리우레탄 수지를 사용한 발포 투습 방습 방수포와 그 제조 방법에 관한 것이다.TECHNICAL FIELD The present invention relates to a foamed moisture vapor barrier and a manufacturing method thereof, and more particularly, to a foamed moisture vapor barrier and a manufacturing method thereof using a polyurethane resin.
일반적으로 빗방울의 직경은 안개비인 경우 100㎛, 소낙비가 3000㎛인 반면에 수증기의 분자 직경은 0.0004㎛에 지나지 않으므로, 원단에 0.1~10㎛ 정도의 미세공을 갖는 피막층을 형성시키면 투습성과 방수성을 동시에 얻을 수 있다. Generally, the diameter of raindrops is 100㎛ for fog ratio and 3,000㎛ for rain shower, whereas the molecular diameter of water vapor is only 0.0004㎛. Therefore, if the film layer having 0.1 ~ 10㎛ micropores is formed on the fabric, moisture permeability and waterproofness Can be obtained at the same time.
다공질층은 폴리테트라플루오르에틸렌(PTFE)와 같은 다공질 피막이나 코팅 피막으로 형성 가능하지만, 섬유 간의 공극을 10㎛ 이하로 치밀하게 만든 고밀도 직물도 유사한 효과를 얻을 수 있다. The porous layer may be formed of a porous film or a coating film such as polytetrafluoroethylene (PTFE), but a similar effect can be obtained with a high-density fabric having densified voids between fibers of 10 μm or less.
그리고 무공질 피막 층도 친수기를 적용하면 다공질 막과 동일한 투습 방수포를 얻을 수 있다.In addition, when the hydrophilic group is applied to the non-porous coating layer, the same moisture-permeable tarp as the porous membrane can be obtained.
투습방수 소재에는 다양한 종류가 있으며, 제조법으로 분류하면 먼저 후 가공 기술과 고밀도 직물로 대별되고, 후 가공 기술은 코팅과 라미네이팅으로 나누어진다. There are various types of moisture-permeable waterproof materials, and when classified into manufacturing methods, they are first divided into post-processing technology and high-density fabric, and post-processing technology is divided into coating and laminating.
물성차이로 분류하면 내수압과 투습도의 정도 차이로 분류하는데, 5,000~30,000㎜의 H2O를 고내수압형, 1,000~2,500㎜ 의H2O를 범용형, 300~800㎜의 H2O를 저내수압형이라 하고, 6,000~13,000 g/m2.24hrs를 고투습형, 2,000~5,000g/m2.24hrs를 범용형, 2000g/g/m2.24hrs 이하를 저투습형이라한다.Divided by the difference in physical properties, it is classified as the difference between the water pressure and the degree of moisture permeability. H 2 O of 5,000 to 30,000 mm is a high water pressure type, H 2 O of 1,000 to 2,500 mm is a general type, and H 2 O of 300 to 800 mm is low. as water pressure resistance type, and is referred to 6,000 ~ 13,000 g / m 2 .24hrs the high moisture-permeable type, 2,000 ~ 5,000g / m 2 .24hrs the generic type, 2000g / g / m 2 .24hrs below the low moisture-permeable type.
코팅기술에는 습식코팅과 건식코팅이 있다. 습식코팅방법은 폴리우레탄수지를 착색제와 조합, 용제로 적절히 조합한 코팅용 수지를 기포지에 코팅한 다음 물에 침적하여 수중으로 용재성분(DMF)을 추출시켜 미세 다공 피막을 형성하는 것이다. Coating techniques include wet coating and dry coating. In the wet coating method, a coating resin obtained by combining a polyurethane resin with a colorant and a solvent, is coated on a bubble paper, and then immersed in water to extract a solvent component (DMF) into water to form a fine porous film.
기포면에 직접코팅한 습식가공은 습식가공에 필요한 별도의 수조 등이 필요하고 넓은 작업공간을 필요로 할 뿐 아니라, 사포 공정 등 추가공정이 뒤따르므로 현재에 이르러서 높은 생산단가와 낮은 생산성, 고품질발현의 한계와 특히 많은 양의 폐수를 발생하게 됨으로써 환경오염의 가능성이 있어서 향후 건식방식이나 라미 네이팅 방식으로 대체될 전망이다. Wet processing directly coated on the bubble surface requires a separate tank for wet processing and requires a wide working space, and additional processes such as sanding process are followed, resulting in high production cost, low productivity, and high quality. There is a possibility of environmental pollution by limiting the expression and especially generating a large amount of wastewater, so it will be replaced by dry or laminating method in the future.
건식 코팅 방식(direct coating)은 용재나 물에 분산시킨 수지를 기포에 도포하여 열에너지로 물 또는 용재를 기화시켜 연속피막을 형성시킨다. 이 방법은 얇은 피막을 형성하는데 용이하며, 안료 및 각종 첨가물 혼합이 용이하여 부가기능을 부여하거나 또는 다양한 코팅표면처리 가공을 할 수 있다. 건식코팅방법을 적용하여 제조하는 투습방수소재는 친수무공형 건식코팅이 있다. 친수무공형 건식코팅에 사용되는 폴리우레탄수지는 분자 내에 도입된, PVA(polyvinyl alcohol)과 PEO(polyethylene oxide)에서 유도된 친수성 관능기가 물을 흡수하여 점차적으로 인접한 다른 친수성 관능기로 확산시키는 원리에 의하여 투습 능력을 갖게 된다.In the direct coating method, a resin dispersed in a solvent or water is applied to a bubble to vaporize water or a solvent with thermal energy to form a continuous film. This method is easy to form a thin film, and the pigment and various additives can be easily mixed to give additional functions or various coating surface treatments. The moisture-permeable waterproof material manufactured by applying the dry coating method is a hydrophilic non-porous type dry coating. Polyurethane resins used in hydrophilic non-porous dry coatings are based on the principle that hydrophilic functional groups derived from PVA (polyvinyl alcohol) and PEO (polyethylene oxide), which are introduced into the molecule, absorb water and gradually diffuse to other adjacent hydrophilic functional groups. You have the ability to breathe.
이 방식은 사용된 폴리우레탄 수지의 친수성 정도와 코팅층의 두께에 의해 투습성이 결정된다. 충분한 방수 및 내수압을 보유하나 투습 능력은 아직 미세 다공질에 미치지 못한다. 친수성 폴리우레탄 수지를 이용 건식코팅법으로 생산한 친수무공형 투습 방수포는 미세 다공성 피막을 이용한 제품보다 투습도는 낮으나 공정이 간단하여 생산원가가 낮고, 생산성이 높아 실용적이나 촉감의 유연성이 떨어져서 고급 제품으로 사용되지 못한다.This method determines the moisture permeability by the degree of hydrophilicity of the polyurethane resin used and the thickness of the coating layer. It has sufficient waterproof and water pressure, but its moisture permeability is still less than microporous. Hydrophilic air-permeable tarpaulin produced by dry coating method using hydrophilic polyurethane resin has lower moisture permeability than products using microporous coating, but it is simple in process and low in production cost, and high in productivity. Not used.
또한 이러한 기능성 적층 원단에 관한 일 예가 대한민국 공개특허공보 2004-010164호(2004년12월03일) 등에 개시되어 있다.In addition, an example of such a functional laminated fabric is disclosed in Korean Patent Laid-Open Publication No. 2004-010164 (December 03, 2004) and the like.
즉, 상기 공개특허공보 2004-010164호에는 도 1 및 도 2에 도시된 바와 같이, 기능성 적층원단은 기초 포지(1)상에 폴리 우레탄 접착제 조성물로부터 형성된 접착 필름층(2) 및 음이온방출 물질을 함유하는 폴리우레탄 수지 조성물로부터 형성된 표면 필름층(3)이 순차적으로 적층되고, 기능성 3중 적층원단은 표면 필름층(3)이 기초 포지(1)와 별도로 이형지상에서 형성되어, 접착제층(2)을 통하여 기초포지(1)와 접합되는 구조를 가짐으로써, 음이온방출 물질을 염색을 통하거나 바인더를 사용하여 고착시키는 방식에 비하여, 보다 견고하게 다량의 음이온방출 물질을 원단에 결착시킬 수 있다. That is, as shown in FIGS. 1 and 2, the functional laminated fabric is formed by using the
이러한 기능성 적층 원단은 이형지(21)상에 필름코터(22)를 이용하여 폴리우레탄 수지 조성물을 도포하고, 이때 상기 조성물은 두께가 10-200㎛의 피막을 형성하도록 한 후, 90-130℃의 건조기(23)에서 건조시키며, 소망하는 도포량의 폴리우레탄 수지 조성물은 이형지(21) 상에 2회 이상에 걸쳐 도포 및 건조되는 과정을 반복한다.This functional laminated fabric is applied to the polyurethane resin composition using a
또, 피막형성 과정을 수회에 걸쳐 반복함으로써 기계적 물성 및 내구성이 더욱 향상된 적층 피막을 얻을 수 있고, 특히, 건조기(23)내의 온도는 센서를 이용하여 이형지가 이동하는 방향으로 순차적으로 100℃ 및 120℃가 되도록 유지시키며, 이형지(21)상에 형성된 폴리우레탄 표면 필름층에, 두께가 10-100㎛인 피막을 형성하도록, 접착제 코터(24)를 이용하여 폴리우레탄 접착제 조성물을 도포한 후, 100-135℃의 건조기(25)에서 건조한다. 특히, 건조기(25) 내의 온도는 센서를 이용하여 이형지 진행방향으로 순차적으로 120℃, 125℃ 및 130℃가 되도록 유지시키며, 그 단계로서, 이형지 상에 순차적으로 형성된 폴리우레탄 표면 필름 층 및 폴리우레탄 접착 필름 층상에 가압 및/또는 가열함으로써 기초포지(26)를 접착시킨다. 이때 사용되는 기초포지는 직물, 편물, 또는 부직포 등이 모두 가능하 나, 최종 기능성 원단이 유연성 및 신축성, 우수한 착용감 등을 나타내기 위해서는 편물을 사용하는 것이 바람직하다고 기재되어 있다.In addition, by repeating the film forming process several times, a laminated film having improved mechanical properties and durability can be obtained. In particular, the temperature in the
그러나, 상술한 문헌 등에 개시된 기술에 있어서, 기능성 적층원단에 음이온방출 물질을 결착시키는 구조에 대해서만 개시되어 있을 뿐, 투습 방수에 관해서는 전혀 개시되어 있지않다. However, in the technique disclosed in the above-mentioned literature and the like, only the structure for binding the anion-releasing material to the functional laminated fabric is disclosed, and no water vapor permeability is disclosed at all.
또 종래의 기술에 의해 제조된 미세다공성 투습 방수포는 기포의 한 단면에 미세 다공성 피막을 접착시킨 것으로 이 소재로 옷을 만들 경우, 인체에서 발생하는 수증기 형태의 물 분자는 미세 다공을 통과하여 외부로 방출되는 투습성이 발휘되고, 빗물과 같은 거대 물 분자는 미세기공을 통과할 수 없음으로 방수성이 발휘되도록 한 것이므로, 땀이 빗물 분자처럼 커진 경우 미세 다공을 통과할 수 없고, 오염에 의한 미세 다공의 막힘은 그 기능성을 현저히 저하시킨다. In addition, the microporous moisture-permeable tarpaulin manufactured by the prior art is a microporous coating film adhered to one end surface of the bubble. When clothes are made of this material, water molecules in the form of water vapor generated in the human body pass through the micropores to the outside. As the moisture permeability is released and the giant water molecules such as rainwater cannot pass through the micropores, the waterproofness is exerted. Therefore, if the sweat is large like the rainwater molecules, the water cannot penetrate through the micropores. Blockage significantly lowers its functionality.
또 종래의 기술에 의한 접착 방법에서 사용되는 접착제는 내수성이 강해서 점을 찍는 방식으로 접착제를 도포하는데, 그 도포 면적에 따라 면적이 넓어지면 기능성이 저하되고, 면적이 좁아지면 세탁내구성을 저하시킨다. In addition, the adhesive used in the adhesive method according to the prior art is water-resistant, and the adhesive is applied in a dotted manner. If the area is widened according to the application area, the adhesiveness decreases, and if the area is narrow, the durability of washing is reduced.
상기와 같이 종래의 미세 다공성 피막을 이용한 가공법에 의한 투습 방수 가공포는 방수성과 통기성 및 투습성을 적절히 조화시키지 못하였기 때문에 실용화 후에도 상당한 결점을 나타냈다. As described above, the moisture-permeable waterproof fabric by the conventional method using a microporous coating has a considerable disadvantage even after practical use because it did not properly balance the waterproofness, breathability and moisture permeability.
즉, 방수성을 중요시하면 투습성이 떨어져서 인체에서 발산하는 땀과 열을 외부로 방출하지 못하고, 투습성에 역점을 두어 미세기공을 크게 하면 방수성이 떨어지거나 필요로 하는 내수압을 얻을 수 없다. In other words, if the importance of waterproofness is poor moisture permeability to release the sweat and heat emitted by the human body to the outside, the emphasis on the moisture permeability to increase the micropores, the waterproofness or the required water pressure can not be obtained.
친수성 폴리우레탄 수지를 이용 라미네이팅(laminating)형식으로 생산한 친수 무공형 투습 방수포는 미세 다공성 피막을 이용한 제품보다 투습도는 낮으나, 공정이 간단하여 생산원가 낮아서 실용적이나 친수성 피막과 친수성 접착제가 물에 의하여 팽윤(swelling) 되므로 세탁내구성을 현저하게 떨어뜨리는 단점이 있었다.Hydrophilic non-porous moisture-permeable tarpaulin produced in the form of laminating using hydrophilic polyurethane resin has lower moisture permeability than the product using microporous coating, but the process is simple and the production cost is low due to the simple process. (swelling), so there was a disadvantage that the washing durability significantly drops.
본 발명의 목적은 상술한 바와 같은 미세 다공형 투습방수포의 문제점을 해결하기 위해 이루어진 것으로서, 무공형의 친수성 수지를 이용한 투습방수포의 접착력을 개선할 수 있는 발포 투습 방습 방수포와 그 제조 방법을 제공하는 것이다.An object of the present invention is to solve the problems of the microporous water-permeable tarpaulin as described above, to provide a foamed moisture-permeable moisture-proof tarpaulin that can improve the adhesion of the moisture-permeable waterproof cloth using a non-hydrophilic resin and a method of manufacturing the same. will be.

먼저 본 발명의 개념에 대해 설명한다.First, the concept of the present invention will be described.
본 발명에서 사용되는 라미네이팅은 이형지(release paper; RP) 위에 수지를 코팅하여 친수 무공형 혹은 미세 다공질 필름을 제조한 후 이를 접착제로 접합시켜서 투습방수포를 제조하는 방식이다. Laminating used in the present invention is a method of manufacturing a moisture-permeable waterproof cloth by coating a resin on a release paper (RP) to produce a hydrophilic non-porous or microporous film and then bonding it with an adhesive.
접합은 접착제의 도포 형태에 따라 점(Dot) 접합과 전면 접합의 두 가지 방식이 있으나 고투습성, 촉감의 유연성 등 고기능성을 요하는 제품은 점(Dot) 접합을 선호한다. There are two methods of bonding, dot bonding and front bonding, depending on the type of adhesive applied. However, dot bonding is preferred for products requiring high functionality such as high moisture permeability and softness of touch.
라미네이팅 방식의 중요한 기술은 고기능성 박막 필름을 균일하게 제조하는 것이며, 제조된 필름과 원단을 합포하는 기술은 제품 전체의 품질을 좌우하는 것으로서 접착강도, 세탁내구성, 외관상 품위, 부드러운 촉감 발현 등에 유의하여야 한 다. An important technique of the laminating method is to uniformly manufacture a high functional thin film, and the technique of combining the manufactured film and the fabric depends on the quality of the whole product.Attention should be paid to adhesive strength, washing durability, appearance quality, and soft touch. do.
다음에 본 발명에 따른 발포 투습 방습 방수포의 제조 방법에 대해 도 3에 따라 설명한다.Next, the manufacturing method of the moisture permeable moisture proof tarpaulin which concerns on this invention is demonstrated according to FIG.
도 3은 본 발명에 따른 발포 투습 방습 방수포의 제조 방법을 설명하기 위한 흐름도이다.Figure 3 is a flow chart for explaining a method of manufacturing a foam moisture permeable waterproof tarpaulin according to the present invention.
본 발명은 투습방수포를 제조함에 있어서 친수성인 변성폴리우레탄 수지에 극미립자상의 열가소성 수지 미소구체에 이소부탄, 이소펜탄, n-펜탄 등 액화시킨 저융점 탄화수소를 내포한 2중 구조의 플라스틱 미소구체(평균입자 10-30㎛)를 마련하고(S10), 2중 구조의 플라스틱 미소구체를 친수성인 변성폴리우레탄 수지에 투입 후(S20), 이형지(RP)에 도포한다(S30).The present invention provides a double-molecular plastic microsphere containing a low-melting-point hydrocarbon such as isobutane, isopentane, and n-pentane in a microparticle-like thermoplastic resin microsphere in a hydrophilic modified polyurethane resin. An average particle of 10-30 μm) is prepared (S10), and the plastic microspheres of the double structure are added to a hydrophilic modified polyurethane resin (S20), and then coated on a release paper (RP) (S30).
다음에 예를 들어 도 2에 도시한 바와 같은 장치를 사용하여 이형지에 열을 가해(S40) 미소구체를 팽창시켜(S50) 친수성의 발포 표층을 형성한다(S50). Next, using a device as shown in FIG. 2, heat is applied to the release paper (S40) to expand the microspheres (S50) to form a hydrophilic foam surface layer (S50).
이때 미소구체가 50~80㎛ 정도로 팽창된 피막(skin)은 촉감이 유연하고 두께감을 갖으며 미세한 구멍을 갖게 된다. 이는 물분자의 크기에 관계없이 친수성의 수지층에서 일단 몸으로부터 발생된 땀을 흡수한 다음에 외부로 방출시키기 때문에 쾌적성을 크게 향상시키며, 미소구체가 팽창할 때 생긴 미세한 구멍은 미세 다공형 투습 방수포의 장점을 갖게 한다. At this time, the film (skin) in which the microspheres are expanded to about 50 ~ 80㎛ has a soft touch, has a sense of thickness and has a fine hole. Regardless of the size of the water molecules, the hydrophilic resin layer absorbs the sweat generated from the body and then releases it to the outside, greatly improving comfort, and the fine pores generated when the microspheres expand are fine porous breathing. It has the advantage of a tarpaulin.
또한 발포체의 장점인 보온성을 갖게 됨을 장점으로 한다. 이 같은 장점으로 인하여 체온과 외부 온도 간의 차이로 인하여 발생되는 결로현상이 발생하지 않는다.In addition, the advantage of having a thermal insulation which is an advantage of the foam. Due to this advantage, no condensation occurs due to the difference between body temperature and external temperature.
본 발명에서는 라미네이팅을 위한 접합방식은 전면접합으로 하는데, 이때 친수성 폴리우레탄수지와 이에 상응하는 경화제만을 사용하게 되면 세탁시, 경화된 접착수지에 팽윤이 발생하여 세탁 내구성을 현저하게 떨어뜨린다. In the present invention, the bonding method for laminating is a front bonding, in which only the hydrophilic polyurethane resin and the corresponding curing agent are used, when washing, swelling occurs in the cured adhesive resin, thereby significantly reducing the laundry durability.
이것을 방지하기 위하여 이소시아네이트(-NCO)를 말단기로하는 프레폴리머를 도입하여 투습성의 급격한 저하를 막으며, 접착력을 향상시켜서 세탁내구성을 향상시켰다. In order to prevent this, a prepolymer having an isocyanate (-NCO) as a terminal group was introduced to prevent a sudden decrease in moisture permeability, and improved adhesion to improve washing durability.
이때 도입한 프레폴리머의 NCO%는 1~3%로 한다. 분자량은 6,000~10,000으로 하고 분자내 관능기 수를 2로 한다. 이하 실시예의 설명에 있어서는 본 발명에 따른 가교제로서의 프레폴리머를 "SJ-200(개발품)"이라 명명하고, 이를 사용하여 기술한다.The NCO% of the prepolymer introduced at this time is 1 to 3%. The molecular weight is 6,000 to 10,000 and the number of functional groups in the molecule is 2. In the description of the following examples, the prepolymer as a crosslinking agent according to the present invention will be referred to as "SJ-200 (developed product)" and described using this.
본 발명에 따른 투습방수포는 투습도가 8.000g/m2.24hrs이며, 내수압은 10,000㎜H2O 이상이다. 아울러 수지층과 기포 간의 접착강도는 2.0Kg/㎠이상이다.The moisture-permeable waterproof cloth according to the present invention has a water vapor transmission rate of 8.000 g / m 2 .24 hrs and a water pressure of 10,000 mmH 2 O or more. In addition, the adhesive strength between the resin layer and the bubble is more than 2.0Kg / ㎠.
이하, 본 발명의 제조방법을 상세히 설명하면 다음과 같다.Hereinafter, the manufacturing method of the present invention will be described in detail.
