Abstract
본 발명은 콘크리트 구조물의 단열방수 시공에 적용되는 결로방지 복합단열시트 및 이를 이용한 노출 시트방수공법에 관한 것으로서, 좀더 구체적으로 설명하면, 건물의 옥상, 콘크리트 바닥면 등에 설치되며 콘크리트 구조물면과 방수층 사이에 발생하는 습기를 고흡수성 시트를 활용하여 흡수 및 배출함으로서, 콘크리트 구조물의 균열 등에 의한 건축물 수명 단축을 예방 내지 지연시킬 수 있는 결로방지 복합단열시트 및 이를 이용한 노출 시트방수공법에 관한 것이다.The present invention relates to an anti-condensation composite insulation sheet applied to the insulation and waterproofing of a concrete structure and an exposed sheet waterproofing method using the same. To be more specific, it is installed on the roof of a building, a concrete floor, etc., and is installed between the concrete structure surface and the waterproofing layer. This relates to an anti-condensation composite insulation sheet that can prevent or delay shortening of the lifespan of a building due to cracks in concrete structures by absorbing and discharging moisture generated using a highly absorbent sheet and an exposed sheet waterproofing method using the same.
Description
본 발명은 콘크리트 구조물에 적용되는 결로방지 복합단열시트를 이용한 노출 시트방수공법에 관한 것으로서, 건물의 옥상, 콘크리트 바닥면 등에 설치되며 콘크리트 구조물면과 방수층 사이에 발생하는 습기를 고흡수성 시트를 활용하여 흡수 및 배출함으로서, 콘크리트 구조물의 균열 등에 의한 건축물 수명 단축을 예방 내지 지연시킬 수 있는 발명에 관한 것이다.The present invention relates to an exposed sheet waterproofing method using an anti-condensation composite insulation sheet applied to a concrete structure. It is installed on the roof of a building, a concrete floor, etc., and uses a highly absorbent sheet to absorb moisture generated between the concrete structure surface and the waterproofing layer. It relates to an invention that can prevent or delay the shortening of the lifespan of a building due to cracks in concrete structures by absorbing and discharging it.
건물 옥상 등의 방수공사시 기존 콘크리트면 또는 도장 면 위로 방수공사를 수행하는데, 콘크리트 구조물은 방수력이 약하기 때문에 빗물이 스며들게 되며, 일정 기간이 지나면 콘크리트 자체에 함유된 수분이 상기 콘크리트 수분의 증발로 수증기가 발생하게 되고, 이러한 수증기로 인해 바닥면과 방수층 및/또는 표면층간 접착성능이 떨어져 박리현상을 일으켜 공기층(Air Pocket)을 형성되며, 이로 인해 방수층의 수명 단축 및 콘크리트 열화현상이나 온도변화에 따른 체적변화에 의해 콘크리트 균열 및 노후화가 발생하여 건축물의 수명이 단축되는 문제가 있다.During waterproofing work on the roof of a building, etc., waterproofing work is performed on the existing concrete surface or painted surface. Since concrete structures have weak waterproofing properties, rainwater seeps in, and after a certain period of time, the moisture contained in the concrete itself becomes water vapor due to evaporation of the concrete moisture. This occurs, and due to this water vapor, the adhesive performance between the floor and the waterproofing layer and/or the surface layer decreases, causing delamination and forming an air pocket, which shortens the lifespan of the waterproofing layer and causes concrete deterioration or temperature changes. There is a problem that concrete cracks and deterioration occur due to volume changes, shortening the lifespan of the building.
이를 방지하기 위하여, 콘크리트 구조물의 옥상, 바닥 등과 같이 물과 직접 면하는 장소에서는 물이 구조물 내부로 침투하지 않도록 방수층을 설치하는데, 효율적이면서 효과가 우수한 방수시공을 위한 다양한 연구, 시도가 있으며, 기존 시공방법은 대부분 폴리우레탄계 소재의 도막 방수재를 도포하여 시공하고 있으나, 방수재의 도막 형성을 위한 건조 시간 등이 많이 필요하여 전체적인 방수 시공 시간이 너무 길어지는 단점이 있고, 콘크리트 구조물에 흡수된 습기의 원활한 배출이 되지 않는 문제가 있었다. To prevent this, a waterproof layer is installed in places that directly face water, such as the rooftop or floor of a concrete structure, to prevent water from penetrating into the structure. There are various studies and attempts to achieve efficient and effective waterproofing construction. The construction method is mostly by applying a waterproofing film made of polyurethane-based material, but it has the disadvantage of requiring a lot of drying time to form a film of waterproofing material, which makes the overall waterproofing construction time too long, and it is difficult to prevent moisture absorbed in the concrete structure from flowing smoothly. There was a problem with it not being discharged.
본 발명은 옥상, 건물 주차장, 배수로 등의 콘크리트 구조물과 방수층에서 발생하는 공기층의 발생을 방지하기 위해, 콘크리트 모체의 습기가 외부로 빠르게 배출될 수 있도록 바탕면에 콘크리트의 수분, 습기를 빠르게 흡수 및 외부로 배출하여 결로 등이 발생하는 문제를 해결할 수 있는 결로방지 복합단열시트 및 이를 이용한 노출 시트방수공법을 제공하고자 한다.The present invention is to quickly absorb moisture and moisture from the concrete on the base surface so that the moisture from the concrete matrix can be quickly discharged to the outside in order to prevent the occurrence of air layers in concrete structures and waterproofing layers such as rooftops, building parking lots, and drainage channels. We aim to provide an anti-condensation composite insulation sheet and an exposed sheet waterproofing method using it that can solve the problem of condensation occurring by discharging to the outside.

The transfer heat reflection layer is composed of an aluminum film, aluminum sheet, or aluminum tape, and serves to block not only radiant heat transmitted from the outside, but also heat transfer by convection or conduction, and reduces the condensation rate due to the secondary insulation effect. It plays a lowering role. Additionally, the transfer heat reflection layer can be formed by applying an adhesive or adhesive to one side of the superabsorbent sheet layer, then adhering or adhering an aluminum sheet or aluminum film, or attaching an aluminum tape to one side of the superabsorbent sheet layer.
그리고, 전사열 반사층의 두께는 1 ~ 70㎛, 바람직하게는 5 ~ 50㎛ , 더욱 바람직하게는 8 ~ 30㎛ 정도인 것이 적절하며, 두께가 1㎛ 미만이면 쉽게 파손되거나 열차단, 단열 효과가 미비할 수 있으며, 70㎛를 초과하는 것은 비경제적이다.In addition, the thickness of the transfer heat reflecting layer is appropriately 1 to 70㎛, preferably 5 to 50㎛, and more preferably 8 to 30㎛. If the thickness is less than 1㎛, it is easily damaged or has no heat blocking or thermal insulation effect. It may be insufficient, and exceeding 70㎛ is uneconomical.
그리고, 상기 수분 고흡수성 시트층은 단층 또는 다수층의 니들펀칭 부직포로 구성된다. 그리고, 상기 니들펀칭 부직포는 단층 기준으로 두께 50 ~ 200㎛ 및 평량 400 ~ 1,000 g/m2, 바람직하게는 두께 60 ~ 180㎛ 및 평량 420 ~ 650 g/m2, 더욱 바람직하게는 두께 60 ~ 170㎛ 및 평량 450 ~ 550 g/m2 정도인 것이 적절하다.And, the moisture-absorbent sheet layer is composed of a single-layer or multi-layer needle-punched non-woven fabric.

There is a problem that the effect of releasing it from the outside is reduced, and there may be a problem that physical properties such as mechanical strength become too weak, so it is advantageous to have a porosity within the above range.

상기 엘라스토머 수지(또는 엘라스토머 칩)는 산 성분과 디올 성분을 1 : 1.0 ~ 1.2 몰비로 중합시킨 중합체로서, 상기 산 성분은 테레프탈산 및 이소프탈산을 1 : 0.2 ~ 0.3 몰비로 포함하며, 바람직하게는 테레프탈산 및 이소프탈산을 1 : 0.25 ~ 0.30 몰비로 포함한다.The elastomer resin (or elastomer chip) is a polymer obtained by polymerizing an acid component and a diol component at a molar ratio of 1:1.0 to 1.2, and the acid component includes terephthalic acid and isophthalic acid at a molar ratio of 1:0.2 to 0.3, preferably terephthalic acid. and isophthalic acid at a molar ratio of 1:0.25 to 0.30.

At this time, if the 2-methyl-1,3-propanediol content is less than 10 mol% or the 2-methyl-1,3-pentanediol content exceeds 5 mol%, the pore formation rate in the elastomer constituting the core layer is too high. There may be a low problem, and if the 2-methyl-1,3-propanediol content exceeds 30 mol%, or the 2-methyl-1,3-pentanediol content is less than 3 mol%, the pore formation rate is too high and the core Since the mechanical properties of the layer are too low, it may cause problems with insufficient shape retention of the hollow fiber, so it is appropriate to use it within the above range.

(3) 수분흡수율 측정(3) Measurement of moisture absorption rate
부직포의 수분 흡수율은 부직포의 양면 중 일면 방향으로 부직포의 두께 1/5 정도를 물에 5분간 침지시킨 후, 침진 전후의 무게를 비교하여, 백분율화하여 수분 흡수율(%)을 측정하였다. The moisture absorption rate of the nonwoven fabric was measured by immersing about 1/5 of the thickness of the nonwoven fabric in water for 5 minutes on one side of both sides of the nonwoven fabric, comparing the weight before and after immersion, and calculating the moisture absorption rate (%).
상기 표 1의 물성 측정 결과를 살펴보면, 기존 니들펀칭 부직포인 비교예 1과 비교할 때, 실시예 1 ~ 6의 부직포가 수분 흡수율이 상대적으로 매우 높으면서도, 방수시공에 사용하기 적합한 인장강도 및 탄성회복률을 가지는 것을 확인할 수 있었다. Looking at the physical property measurement results in Table 1, compared to Comparative Example 1, which is a conventional needle-punched nonwoven fabric, the nonwoven fabrics of Examples 1 to 6 have relatively high moisture absorption rates and tensile strength and elastic recovery rate suitable for use in waterproofing construction. It was confirmed that it had .
그리고, 중공형 섬유의 중공율이 10% 미만인 8.8%인 중공형 섬유로 제조한 비교예 2의 경우, 실시예 1(중공율 13.5%) 및 실시예 2(중공율 10.4%)와 비교할 때, 인장강도 및 탄성회복률은 유사하면서, 수분 흡수율이 급격하게 감소하는 문제가 있었다. 또한, 중공형 섬유의 중공율이 20%를 초과한 20.7%인 중공형 섬유로 제조한 비교예 3의 경우, 실시예 1(중공율 13.5%) 및 실시예 3(중공율 17.6%)와 비교할 때, 수분 흡수율은 우수하나, 인장강도 및 탄성회복률이 크게 감소하는 문제가 있었다.And, in the case of Comparative Example 2 manufactured with hollow fibers with a hollow fiber of 8.8%, which is less than 10%, when compared to Example 1 (porosity of 13.5%) and Example 2 (porosity of 10.4%), Although the tensile strength and elastic recovery rate were similar, there was a problem in that the moisture absorption rate rapidly decreased. In addition, in the case of Comparative Example 3 manufactured with hollow fibers whose porosity is 20.7%, which is more than 20%, compared to Example 1 (porosity 13.5%) and Example 3 (porosity 17.6%) Although the moisture absorption rate was excellent, there was a problem in that the tensile strength and elastic recovery rate were greatly reduced.

In addition, in the case of Comparative Example 5, in which the sheath layer thickness ratio compared to the core layer exceeded 3.0, compared to Examples 1 (1:2.3) and Example 5 (1:2.8), the water absorption rate was high, but the tensile strength and elasticity were low. There was a problem where the recovery rate decreased significantly.
그리고, 바인더 단섬유를 사용하여 제조한 실시예 6의 니들펀칭 부직포는 실시예 1과 비교할 때, 수분 흡수율은 다소 5% 정도 떨어지지만 상대적으로 높은 인장강도 및 증가된 탄성회복률을 가졌다. 이에 반해, 바인더 단섬유를 부직포 내 20 중량% 초과하여 사용한 비교예 6의 경우, 매우 높은 인장강도와 탄성회복률을 가지지만 수분 흡수율이 급격하게 감소하는 문제가 있었다. And, compared to Example 1, the needle-punched nonwoven fabric of Example 6 manufactured using binder short fibers had a relatively high tensile strength and increased elastic recovery rate, although the moisture absorption rate was slightly lower by about 5%. On the other hand, in the case of Comparative Example 6, in which binder single fibers were used in an amount exceeding 20% by weight in the nonwoven fabric, although it had very high tensile strength and elastic recovery rate, there was a problem in that the moisture absorption rate decreased rapidly.
