Description

자착식 필름 방수시트 및 그 방수공법{Waterproof sheet and waterproof method}Self-adhesive film waterproof sheet and its waterproofing method

본 발명은 자착식 필름 방수시트 및 그 방수공법에 관한 것으로, 특히, 온도의 편차가 심한 지역에서의 방수시공 시 방수층의 물성변화를 방지하고, 방수시트의 물성변화에 따른 방수시트 파손문제를 해소하며, 시공이 단순화되면서도 하자의 발생을 최소화하고, 안정된 방수시공 및 방수층의 수명이 오랫동안 유지되게 하는 자착식 필름 방수시트 및 그 방수공법을 제공한다.The present invention relates to a self-adhesive film waterproof sheet and its waterproofing method, in particular, to prevent changes in the properties of the waterproof layer during waterproof construction in areas where temperature fluctuations are severe, and to solve the problem of damage to the waterproof sheet due to changes in the properties of the waterproof sheet. In addition, it provides a self-supporting film waterproof sheet and its waterproof method to minimize the occurrence of defects while simplifying the construction, and to maintain a stable waterproof construction and the life of the waterproof layer for a long time.

건물이 대형화되면서 옥상의 형태가 평면화되어 옥상에 고인 빗물이 건물 내부로 누수될 확률이 높아지고 있으며, 옥상 슬라브로 빗물이 스며드는 것을 방지하기 위한 여러 방수시공 공법 중 아스팔트시트 또는 액상의 도막제 등으로 시공하는 공법이 현재 가장 많이 사용되고 있다.As the size of the building becomes larger, the shape of the rooftop is flattened, and the probability of rainwater leaking into the building increases.In addition, it is used as an asphalt sheet or liquid coating agent among various waterproof construction methods to prevent rainwater from seeping into the rooftop slab. The most commonly used method is currently used.

즉, 바탕면에 일반적으로 사용되어지고 있는 프라이머(3)를 도포하고, 프라이머 시공후 건조가 완료되면 그 위에 일반 방수시트를 부착하여 방수층을 형성하거나 또는 일반 도막방수재를 도포하여 방수층을 형성한다. That is, the primer (3) which is generally used on the base surface is applied, and when the drying is completed after the primer construction, the general waterproof sheet is attached thereto to form a waterproof layer or a general coating waterproofing material is applied to form a waterproof layer.

상기 방수시트 또는 도막방수재의 방수 시공이 완료되면 방수층을 보호할 목 적으로 시멘트와 모래를 혼합한 시멘트 몰탈을 이용해서 보호 몰탈층 타설한다. When the waterproof construction of the waterproof sheet or the coating waterproofing is completed, a protective mortar layer is poured using cement mortar mixed with cement for the purpose of protecting the waterproof layer.

그리고, 바탕면으로부터 방수방수층의 들뜸 방지를 위해 시멘트, 모래, 자갈로 구성되는 보호누름층을 타설함으로써, 방수공법이 완료될 수 있다.And, by pouring a protective pressing layer consisting of cement, sand, gravel to prevent the lifting of the waterproof waterproof layer from the base surface, the waterproof method can be completed.

여기서, 상기 방수시트는 주로 아스팔트계 시트가 사용되고, 도막방수재는 주로 우레탄 도막 방수재나 무기질 탄성 도막방수재 등이 사용된다.Here, the waterproof sheet is mainly used asphalt-based sheet, the coating film waterproofing material is mainly used for urethane coating film waterproofing material or inorganic elastic coating film waterproofing material.

그러나, 상기 종래 방수공법에서 아스팔트계 시트를 사용할 경우, 현장에서 고체상태의 아스팔트를 가열 용융하여 점성이 높은 반고체상태로 만든 후, 바탕면에 부착하여야 하는 불편함이 있었으며, 이로 인하여 작업속도가 지연되며, 작업 시 작업자가 화상의 위험에 노출될 수 있으므로, 인건비 상승 등 전체적으로 시공에 소요되는 비용이 증가될 수밖에 없는 문제점이 있었다.However, when the asphalt sheet is used in the conventional waterproof method, there is an inconvenience to be attached to the base surface after heating and melting the solid asphalt in the field to make it a highly viscous semi-solid state, thereby delaying the work speed. And, since the worker may be exposed to the risk of burns during work, there is a problem that the cost required for construction as a whole, such as increase in labor costs will have to increase.

아울러, 상기한 아스팔트계 시트의 아스팔트는 열에 약하여 우리나라와 같이 사계절이 뚜렷하고, 여름과 겨울의 온도편차가 심할 경우에는 아스팔트의 물성이 파괴됨은 물론 영하의 온도에서 바탕면이 거동하게 되면 아스팔트계 시트가 미세하게 깨지거나 파손되는 등의 문제점이 발생하게 된다.In addition, the asphalt of the asphalt sheet is weak to heat, so the four seasons are clear, as in Korea, if the temperature deviation in summer and winter is severe, the properties of the asphalt are destroyed, as well as the asphalt surface sheet at sub-zero temperatures. Problems such as being broken or broken finely occur.

상기한 바와 같이 아스팔트계 시트가 온도 편차에 의하여 깨지거나 손상되는 현상이 반복되면 그로 인한 크랙의 증가로 들뜸현상이 발생할 수 있으며, 여름철 각종 강우에 의한 단기적인 수분영향과 지하수에 의한 장기적인 수분영향으로 말미암아 결국, 방수층 하부로 물이 스며들게 되므로 방수층의 수명이 오랜기간 동안 보장되지 못한다는 문제점이 있었다.As described above, if the asphalt sheet is broken or damaged due to temperature variation, the crack may increase due to the increase of cracks, and short-term water effects due to various rainfalls in summer and long-term water effects due to groundwater may occur. As a result, the water soaked into the lower portion of the waterproof layer has a problem that the life of the waterproof layer is not guaranteed for a long time.

상기한 문제점은 강우와 지하수에 포함되어 있는 각종 산, 알카리, 염소, 오 일, 오염 물질 등이 바탕면으로 스며들어 철근콘크리트 구조물의 중성화 촉진과 철근의 부식에 따른 내구성능 저하를 일으켜 2차적으로 철근 콘크리트 구조물의 잔존수명을 현저하게 단축시키거나 구조물 자체의 안정성을 저해하는 등의 문제점으로 확산될 수 있다.The above problems are secondary to acidity, alkali, chlorine, oil, pollutants, etc. contained in rainfall and groundwater, soaking into the ground surface, promoting neutralization of reinforced concrete structures and deteriorating durability due to corrosion of steel. It may spread to problems such as significantly shortening the remaining life of the reinforced concrete structure or inhibiting the stability of the structure itself.

아울러, 대부분의 방수시트에는 누름콘크리트 타설 시 방수층을 보호하기 위하여 방수보호층을 방수층 상부에 부착하는 방식으로 제조되는 바, 상기 방수보호층은 대부분 HDPE, EVA, PVC, EPDM, PET와 같은 재질로 이루어진 필름지로서, 방수시트와 방수시트를 연결하는 부위는 맞댐이음이나 겹침이음에도 대부분 도막방수재를 도포하는 바, 이때, 상기 도막방수재가 방수보호층의 상부에 도포되면서 방수보호층이 도막방수재측을 향하여 편향되게 연신됨으로써, 다른 부위도 도막방수재가 도포된 측을 향하여 연신되면서 방수보호층이 파형의 물결치는 모양으로 변형시키는 문제점이 있었다.In addition, most of the waterproof sheet is manufactured by attaching a waterproof protective layer on top of the waterproof layer in order to protect the waterproof layer when pressing concrete, the waterproof protective layer is mostly made of a material such as HDPE, EVA, PVC, EPDM, PET As the film paper, the part connecting the waterproof sheet and the waterproof sheet is coated with most of the waterproof film even in the joint or overlapping joint, wherein the waterproof film is applied to the upper portion of the waterproof protective layer, the waterproof protective layer is coated By being stretched outwardly toward the other side, other parts were also drawn toward the side to which the coating waterproofing material was applied, and there was a problem in that the waterproof protective layer was deformed into the wavy shape of the wave.

이러한 문제점은 방수시트를 연결하는 부위가 도막방수재에 의하여 일체화됨으로써, 연결부위를 통한 침수현상을 방지하고자 함이 주된 목적인 바, HDPE, EVA, PVC, EPDM, PET 등의 재질로 이루어진 종래의 방수보호층이 열에도 약하며 도막방수재와의 일체성이 낮아 쉽게 분리되므로 방수성능을 저해하는 요인으로 작용하게 된다.The problem is that the part connecting the waterproof sheet is integrated by the coating waterproof material, the main purpose is to prevent the immersion through the connecting part, the conventional waterproof protection made of a material such as HDPE, EVA, PVC, EPDM, PET The layer is also weak against heat and is easily separated because of its low integrity with the coating waterproofing material, thus acting as a factor that inhibits the waterproof performance.

본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 열을 가하지 않고도 방수층이 바탕면에 용이하게 부착시킬 수 있음은 물론, 계절에 관계없이 저온이나 고온에서도 물성이 변화하지 않고, 파괴되지 않을 뿐만 아니라 바탕면 또는 구조체의 균열 및 진동, 충격 및 거동에 대하여 유연하게 충격을 흡수하게 하고, 방수층의 인장강도와 인열강도를 보강 및 증대시키며, 도막방수재 도포 시 방수보호층이 어느 한쪽을 향하여 편향되지 않도록 함은 물론, 우레탄 도막재에 부틸시트가 녹아서 방수층이 파괴되거나 우레탄 도막재가 탈리되는 종래의 문제점을 해결하여 옥외방수 및 노출방수시공 시 우레탄 도막재가 노출되게 하는 방수공법에서의 안정적인 방수시공 및 하자보수의 문제점을 해결할 수 있게 하는 자착식 필름 방수시트 및 그 방수공법을 제공하는 데 그 목적이 있다. The present invention has been made to solve the above problems, the waterproof layer can be easily attached to the base surface without applying heat, as well as the physical properties do not change, even at low or high temperatures regardless of season, Instead, it flexibly absorbs the impact against cracks, vibrations, impacts and behavior of the base surface or structure, reinforces and increases the tensile strength and tear strength of the waterproof layer, and the waterproof protective layer is deflected toward either side when the coating waterproofing material is applied. Stable waterproof construction in the waterproof method to prevent the urethane coating material is exposed to the outdoor waterproof and exposed waterproof construction by solving the conventional problem that the butyl sheet is melted in the urethane coating material is destroyed or the urethane coating material is detached. Self-adhesive film waterproof sheet and its waterproof hole to solve the problem of defect repair For it is an object to provide.

여기서, 상기 강도보강층은, 직포 또는 부직포로 이루어지며, 상기 강도보강층은 유리섬유로 이루어진다.Here, the strength reinforcing layer is made of woven or nonwoven fabric, the strength reinforcing layer is made of glass fiber.

그리고, 상기 부틸고무층의 하부면에 부착되어 방수시공 시 제거되는 이형지를 더 포함하는 것이 바람직하다.And, it is preferable to further include a release paper attached to the lower surface of the butyl rubber layer is removed during waterproofing.

본 발명은 저온과 고온의 온도차가 발생하는 작업환경 또는 사계절이 뚜렷하여 계절별 온도차가 심한 지역의 건물, 주차장 등에 시공되어도 온도의 편차에 의한 재질의 물성이 변화되거나, 방수시트가 파손되는 등의 문제점이 해소될 수 있으며, 방수시공에 사용되는 우레탄 도막방수재와의 일체성을 증대시키고, 우레탄 도막방수재 도포 시 필름의 편향수축 문제를 해소하여 안정된 방수시공 및 방수층의 수명이 오랫동안 유지되게 하는 자착식 필름 방수시트 및 그 방수공법을 제공한다.The present invention is a problem that the physical properties of the material change due to the temperature difference or even the waterproof sheet is damaged even if the construction environment or the parking lot in the region where the temperature difference is severe due to the four seasons are obvious or the four seasons when the temperature difference between the low temperature and high temperature occurs The self-adhesive film can be eliminated and increases the integrity of the urethane coating waterproofing material used for waterproofing, and solves the deflection shrinkage problem of the film when applying the urethane coating waterproofing material to maintain a stable waterproofing and life of the waterproof layer for a long time Provide waterproof sheet and its waterproofing method.

도 1은 본 발명에 따른 자착식 필름 방수시트(100)의 구조를 도시한 부분 분해사시도이고, 도 2는 본 발명에 따른 자착식 필름 방수시트(100)의 시공방법을 시계열적으로 도시한 순서도이고, 도 3은 본 발명에 따른 자착식 필름 방수시트(100)의 시공방법을 도시한 시공상태도이며, 도 4는 본 발명에 따른 자착식 필름 방수시트(100)의 시공단면도이다.1 is a partially exploded perspective view showing the structure of the self-adhesive film waterproof sheet 100 according to the present invention, Figure 2 is a flow chart showing the time-series construction method of the self-adhesive film waterproof sheet 100 according to the present invention. 3 is a construction state diagram illustrating a construction method of the self-adhesive film waterproof sheet 100 according to the present invention, and FIG. 4 is a construction cross-sectional view of the self-adhesive film waterproof sheet 100 according to the present invention.

본 발명에 따른 자착식 필름 방수시트(100)는, 도 1에 도시된 바와 같이 부틸고무층(101), 강도보강층(102) 및 방수보호층(103)으로 크게 구분할 수 있으며, 상기 부틸고무층(101)은, 부틸고무 또는 부틸러버로 명명되는 소재로서, 순도 99% 이상의 이소부틸렌에 1.5∼4.5%의 이소프렌 혼합물과 순수한 메틸클로라이드를 넣고 촉매제로 무수염화알루미늄을 넣은 뒤 중합반응기에 넣어 약 -100℃의 낮은 온도에서 중합하여 만든 고무를 말하며, Isobutylene-Isoprene rubber[IIR]라고 한다. Self-adhesive film waterproof sheet 100 according to the present invention, as shown in Figure 1 can be largely divided into butyl rubber layer 101, strength reinforcing layer 102 and waterproof protective layer 103, the butyl rubber layer 101 ) Is a material called butyl rubber or butyl rubber, isobutylene having a purity of 99% or more, 1.5 to 4.5% of isoprene mixture and pure methyl chloride, anhydrous aluminum chloride as a catalyst, and then put into a polymerization reactor. Refers to a rubber made by polymerization at a low temperature of ℃, Isobutylene-Isoprene rubber [IIR].

상기 소재는 기후의 변화에 잘 견디고 불포화결합이 적어 열이나 오존·산화제에 강하며, 전기절연성이 뛰어나고 충격 흡수성이 우수한 것으로, 탄성체가 잘 결정화하지 않으므로 -50℃ 정도의 낮은 온도에서도 유연성이 있다. The material is resistant to climate change and has a small number of unsaturated bonds, which is resistant to heat, ozone, and oxidizing agent, and has excellent electrical insulation and excellent shock absorption. The elastic body does not crystallize well, and thus has flexibility at a low temperature of about -50 ° C.

상기한 부틸고무층(101)은 자착성이 우수하여 영하의 온도에서도 바탕면(105)에 이 부틸고무층(101)을 부착시키기 위하여 가열할 필요가 없으므로, 방수시공 작업시간이 단축되는 장점을 가지며, 작업을 매우 수월하게 할 수 있다.Since the butyl rubber layer 101 is excellent in self-adhesion property and does not need to be heated to attach the butyl rubber layer 101 to the base surface 105 even at subzero temperatures, the waterproof construction time is shortened. It can make your work very easy.

특히, 계절의 변화에 따른 온도편차에 관계없이 저온, 고온에서도 물성변화가 적으므로, 우리나라와 같이 사계절이 뚜렷한 지역에서는 항상 반고체상태의 물성을 유지하여 구조체의 균열 및 진동과 충격에 매우 유리한 소재이다.In particular, there is little change in physical properties even at low and high temperatures regardless of temperature variations due to seasonal changes. Therefore, it is a material that is very advantageous for cracking, vibration and impact of structures by maintaining semi-solid properties in regions with four distinct seasons like Korea. .

상기한 부틸고무층(101)의 상부면에는 도 1 또는 도 3에 도시된 바와 같이 직포 또는 부직포로 이루어진 강도보강층(102)을 부착하여 부틸고무층(101)의 인장강도와 인열강도가 보강될 수 있게 하며, 바람직하게는 상기 강도보강층(102)은 유리섬유로 성형하는 것이 바람직하다.The tensile strength and tear strength of the butyl rubber layer 101 may be reinforced by attaching the strength reinforcing layer 102 made of a woven or nonwoven fabric to the upper surface of the butyl rubber layer 101 as shown in FIG. 1 or 3. Preferably, the strength reinforcing layer 102 is preferably formed of glass fiber.

아울러, 상기 강도보강층(102)의 상부면에는 나이론 필름으로 이루어진 방수보호필름을 부착하는 바, 이 나이론 필름으로 이루어진 방수보호층(103)은 누름콘크리트 타설 시 부틸고무층(101)이 파손되거나 손상되는 것을 방지하며, 방수시공 시 연결이음부분에 사용되는 우레탄 도막방수재(107)와의 일체성이 우수하여 저온 또는 고온에서도 분리되거나 들뜸현상이 방지된다.In addition, the upper surface of the strength reinforcing layer 102 is attached to the waterproof protective film made of a nylon film, the waterproof protective layer 103 made of the nylon film is damaged or damaged when the butyl rubber layer 101 when pressed concrete It prevents and prevents separation or lifting even at low or high temperature due to excellent integrity with the urethane coating waterproofing material 107 used in the joint portion during waterproof construction.

특히, 기존의 HDPE, EVA, PVC, EPDM, PET 재질은 편향연신 또는 편향신축이 일어나는 반면, 나일론 필름의 경우 이축연신공정에 의해 제작된 것이므로 인장강도, 인장탄성율, 산소 등의 가스차단성, 내열, 내한성이 우수하여 우레탄 도막방수재(107)가 도포되더라도 우레탄 도막방수재(107)가 도포된 부분으로 편향신축 또는 편향연신되지 않음으로써, 시공 후에도 부틸고무층(101)을 안정적으로 보호할 수 있으며, 부틸고무층(101) 및 우레탄 도막방수재(107)와 분리되지 않아 방수층을 안전하게 보호할 수 있게 된다.In particular, while HDPE, EVA, PVC, EPDM, and PET materials are deflected or deflected and stretched, nylon films are manufactured by a biaxial stretching process, so that gas barrier properties such as tensile strength, tensile modulus, oxygen, heat resistance, Even though the urethane coating waterproofing material 107 is applied because of excellent cold resistance, the urethane coating waterproofing material 107 is not stretched or deflected to the coated portion, thereby stably protecting the butyl rubber layer 101 even after construction, and the butyl rubber layer It is not separated from the 101 and the urethane coating waterproofing material 107 it is possible to safely protect the waterproof layer.

즉, 상기한 바와 같이 이축연신 나일론 필름은, 분자 사슬간의 아미드기(- NHCIO-)에 의한 수소결합으로 인해 이축연신이 어려운 고분자였으나, 1960년대에이르러서야 이축연신 필름이 개발되기 시작하였으며, 이축연신 필름이란 압출 다이에서 토출된 미연신 시트를 종횡 양방향으로 연신하여 고분자 사승을 면방향으로 늘린 필름으로, 평면상 이축으로 분자를 배향시킨 것이다.That is, as described above, the biaxially stretched nylon film was a polymer that is difficult to biaxially stretch due to hydrogen bonds between amide groups (-NHCIO-) between molecular chains, but until the 1960s, biaxially stretched films began to be developed. The stretched film is a film in which the unstretched sheet discharged from the extrusion die is stretched in both the longitudinal and transverse directions to increase the polymer square in the plane direction, and the molecules are oriented in the planar biaxial direction.

상기한 이축연신 나일론 필름은 이미 그 사용이 식품 가공업 및 수산물 등의 진공포장에 널리 사용되는 것이므로 그 상세한 설명은 생략하기로 한다.Since the biaxially stretched nylon film is already widely used in vacuum packaging for food processing industry and aquatic products, its detailed description will be omitted.

한편, 본 발명에 따른 자착식 필름 방수시트(100)의 부틸고무층(101) 하부면에는 도 1에 도시된 바와 같이 보관의 용이성 및 물류관리의 용이성을 위하여 이형지(104)를 부착하는 것이 바람직하고, 이 이형지(104)는 방수시공시 제거한다.On the other hand, it is preferable to attach a release paper 104 to the lower surface of the butyl rubber layer 101 of the self-adhesive film waterproof sheet 100 according to the present invention for ease of storage and ease of logistics management as shown in FIG. This release paper 104 is removed during waterproof construction.
