Description

고정부재를 사용하지 않는 열반사투습방수시트 및 이의 제조방법, 시공방법Heat-reflective waterproof sheet not using fixed member, its manufacturing method and construction method

The present invention relates to a heat reflective moisture-permeable waterproof sheet having excellent heat reflection, moisture permeability, and waterproofing, including a heat reflective breathable film layer having an upper, a lower layer, and an aluminum coating layer made of a nonwoven fabric or a fabric. Specifically, it is excellent in heat reflection, moisture permeability and waterproofing, and in the heat reflection moistureproof sheet which improves the handling and work performance of the worker without using a fixing member in order to increase the watertightness when constructing the heat reflection moistureproof sheet on the roof. It is about.
방수시트재는 목조주택에 있어서 방음, 단열 및 방수성을 유지하고, 외부로부터 침입하는 빗물 등을 차단하는 외벽재 또는 지붕재로서 투습, 방수성을 지니고 있다. 따라서 밀폐성이 좋고 옥내에 발생하는 습기를 외부로 효율적으로 배출하여야 하며, 또한 내균성이나 내부식성 등이 우수하여야 한다. The waterproof sheet material has moisture permeability and waterproofness as an exterior wall material or a roofing material that maintains sound insulation, heat insulation, and waterproofness in a wooden house and blocks rainwater invading from the outside. Therefore, the airtightness must be good and the moisture generated indoors must be discharged efficiently to the outside, and also excellent in corrosion resistance and corrosion resistance.
목조주택과 같은 건축물의 지붕구조에는 일반적으로 마룻대와 상반사이에서 여러개의 서까래가 서로 일정한 간격으로 교차된 상태에서 지지가 됨과 동시에 서까래 위에 OSB 구조용 합판 등을 깔아서 산자판을 구성한다. 지붕방수시트는 기와 틈이나 균열로 인하여 스며드는 빗물이 지붕 안으로 새는 것을 완전히 방수 하는 2차 방수재로서 상기의 상판인 OSB합판에 설치하는 마지막 방수시트재임으로 완벽한 방수가 요구된다. 또한, 지붕의 직사광선에 따른 태양열의 복사열을 반사시켜 열차단효과 또는 집안의 복사열을 반사시켜 단열효과를 가져 에너지 효율을 높일 수 있어야 한다.In general, the roof structure of a building such as a wooden house is supported in a state where several rafters intersect at regular intervals between the ridge and the upper half, and at the same time, a living board is constructed by laying OSB structural plywood on the rafters. The roof waterproof sheet is a secondary waterproofing material that completely prevents leaking rainwater leaking into the roof due to cracks, cracks, or cracks. It is the last waterproof sheet to be installed on the top plate of OSB plywood. In addition, by reflecting the radiant heat of the sun according to the direct sunlight of the roof to reflect the heat shielding effect or the radiant heat of the house should be able to increase the energy efficiency by having a heat insulation effect.
상기 방수시트재는 지붕에 사용하는 OSB합판에 부착시키기 위해 주로 햄머, 타카, 스테플러 및 못 등의 고정부재를 이용하는데 스테플러의 침이나 못 등은 방수시트재에 바늘구멍이나 못구멍 등의 틈새가 생겨 방수효과를 현저히 떨어트린다.The waterproof sheet material mainly uses fixing members such as hammers, taka, staplers and nails to attach to the OSB plywood used for the roof. The needles and nails of the stapler have gaps such as needle holes or nail holes in the waterproof sheet material. Significantly reduce the waterproof effect.
종래의 경우, 위에서 기술한 문제점을 해결하기 위하여, 다음과 같은 방법 등이 제시, 사용되고 있었다. 먼저, 이형지를 사용하지 않는 고무계의 개량된 아스팔트 방수시트재가 소개되었다. 하지만 이 제품 역시 기존방법과 동일하게 고정부재를 사용해야하는 한계를 드러냈으며, 40~50 ℃정도로 높은 온도가 유지되는 여름철의 지붕에는 제품이 롤링된 상태에서 접착력이 살아나 롤 중에 겹겹이 붙어버려 한겹씩 띄어내면서 작업해야 하는 불편함이 발생하였다, 또한, 제품표면이 울퉁불퉁하거나 부분적으로 뜯긴 상태로 OSB합판에 붙여야 하는 문제점들이 도출되었으며, 방수효과가 저하되고, 방수시트를 시공 후 구겨진 상태나 겹쳐진 곳, 뜯겨서 핀홀이 발생한 부분을 수정하기 위한 재시공 시 제품을 띄어내기 어렵고, 제품이 손상되어 모두 재시공 해야 하는 2중으로 비용이 들어가는 등의 애로사항이 발생되어 시장에서 외면 당해 왔다.In the related art, in order to solve the problems described above, the following methods and the like have been proposed and used. First, a rubber-based improved asphalt waterproof sheet material without a release paper was introduced. However, this product also showed the limitation of using the fixing member in the same way as the existing method, and the adhesive strength is maintained in the rolled state as the product is rolled up on the roof of the summer in which the temperature is maintained at a high temperature of about 40 ~ 50 ℃. Inconvenience to work on it occurred, and also the problem of attaching to OSB plywood with uneven or partly torn surface of the product was derived, and the waterproofing effect was deteriorated. In case of re-installation to correct the part where pinhole occurred, it is difficult to float the product, and it has been disregarded in the market due to troubles such as double damage that requires re-installation due to damage to the product.
또한, 고정부재를 사용하지 않고 방수시트재를 고정하기 위하여 OSB합판과 방수시트재의 사이에 접착제를 도포하는 방법이 제시되고 있다.   In addition, a method of applying an adhesive between the OSB plywood and the waterproof sheet material in order to fix the waterproof sheet material without using the fixing member has been proposed.
그러나 60~70°로 경사진 지붕에 설치된 OSB합판의 전면에 접착제를 도포하기 쉽지 않고, 전면 도포된 접착제 끈적임 때문에 경사진 지붕 위의 이동이 불편하여 시공 시 어려움이 있었다. 행여 방수시트를 잘못 설치하게 되면 재시공이 불가능하여 종래의 방법보다 작업의 효율성이 떨어지고, 경제성이 현저하게 떨어졌다. 또한, 상기 제품은 방수기능에만 목적을 가졌을 뿐, 투습 또는 열반사기능에 대해서는 기능이 떨어져 수분에 결로현상 제어가 불가능하고, 여름철의 태양 복사열에 의한 에너지관리에도 대책이 없었다.However, it is not easy to apply the adhesive to the front surface of the OSB plywood installed on the inclined roof at 60-70 °, and it is difficult to install because of the uncomfortable movement on the inclined roof due to the adhesive applied on the front. Improper installation of the hanger waterproof sheet makes it impossible to reconstruct, resulting in less work efficiency than the conventional method and significantly lowering economic efficiency. In addition, the product had only the purpose of waterproofing function, the function of moisture permeation or heat reflection function is poor, condensation control is not possible in the moisture, and there is no measure for energy management by solar radiation in summer.
또한, 방수시트재의 한면에 접착제를 전면 도포하면서 박리지 또는 이형지를 삽입하여 롤상태로 감아서 보관하였다가, 필요시에 방수시트재로 사용 할 때 박리지 또는 이형지를 제거하면서 사용하는 제품이 소개되었다. 이는 지붕에서 작업할 때 박리지 또는 이형지를 벗겨가면서 작업을 하게 되는데 이렇게 벗겨진 박리지 또는 이형지는 작업자 발밑 앞에서 쌓여져 작업에 방해되고, 특히, 박리지 또는 이형지에는 매우 미끄러운 실리콘이형제가 전면에 코팅되어 잘못 밟을 경우, 추락사고 등의 안전사고의 문제가 대두되었다. 특히, 박리지는 쓰레기로 처리해야 하는 이중 부담이 되어 시장의 외면을 받아왔다. In addition, the product is used while removing the release paper or release paper when the release sheet or release paper is rolled and stored in roll state while applying the adhesive on one side of the waterproof sheet material. It became. This is done by peeling off the release paper or release paper when working on the roof. The peeled release paper or release paper is piled up in front of the worker's feet, which hinders the work. In particular, the release paper or release paper is coated with a very slippery silicone release agent on the front surface. In case of wrong step, there is a problem of safety accidents such as a fall accident. In particular, the release paper has been a double burden to be disposed of as rubbish has been the outside of the market.
또한, 종래의 제품 중에서 방수시트를 OSB합판에 고정시킨 후에 못주변의 틈새를 막기 위해 고정시킨 부분에 방수시트를 겹쳐서 시공하는 제품도 있으나 이러한 방법은 전체적인 소요량보다 실제 사용량이 많게 되어 비경제적인면이 지적되어왔다.In addition, there are products in which the waterproof sheet is laminated on the part fixed to prevent the gap around the nail after fixing the waterproof sheet to the OSB plywood, but this method is more economical than the overall requirements, which is uneconomical. Has been pointed out.
이외에 종래의 방법인 방수시트재를 아스팔트, 고무 등으로 침적시켜 방수성을 향상시킨 타르계 방수시트가 있다. 그러나 이러한 타르계 방수시트는 타르의 침적으로 인하여 두께가 2~5㎜가 됨으로 롤제품의 중량도 무겁기 때문에 혼자서 다루기가 어렵고, 이로 인해 지붕위에서 작업하는 작업자의 취급성이 현저히 떨어지는 단점이 있다. 타르계의 개량 아스팔트를 주재료로 사용하는 제품 역시 방수기능에만 목표를 하고 열반사 및 투습기능에는 효과가 없는 문제가 있었다. 또한, 고정부재를 사용하여 발생하는 틈새에 따른 방수효과 저하가 발생한다.In addition, there is a tar-based waterproof sheet which improves waterproofness by depositing waterproof sheet material, which is a conventional method, with asphalt or rubber. However, such tar-based waterproof sheet is difficult to handle alone because the weight of the roll product is too heavy due to the thickness of the tar is 2 ~ 5㎜, which has a disadvantage in that the handling of the worker working on the roof is significantly reduced. Products using tar-based improved asphalt as the main material also had problems with only the waterproof function and the heat reflection and moisture permeability. In addition, a decrease in waterproofing effect occurs due to a gap generated by using the fixing member.

At this time, any one or two selected from gravure copper plate and rubber pressure roller Indentation grooves may be dug to generate the adhesive surface and the release surface. When the rubber pressing roller is pressed in this way, the portion where the unevenness is formed passes through the pressure-sensitive adhesive or the release agent by the pressure of the rubber pressure roller. On the other hand, the portion where the groove is formed may be a pressure-sensitive adhesive or a release agent is transferred to the upper layer or the lower layer to form a plurality of adhesive or release surface. This intaglio groove is the gravure copper plate Alternatively, one or more rubber rollers may be formed.
