본 발명은 단열성능을 가진 이중복합직물 방수시트 구조체와 이를 이용한 복합단열시트 방수공법으로서, 좀더 상세하게는 외부 온도 변화에 따른 고무화 아스팔트 시트의 변형 문제를 해결하고 특히 우수한 인장강도와 내구성, 신축성과 방수성능을 가진 합성섬유인 폴리에스테르 섬유와 고강도를 특징으로 하는 유리섬유 직물시트(Fiber glass)를 이중으로 이용하여 제작된 이중복합직물 방수시트와 단열성능이 우수한 보온 부직포 단열시트가 적층된 이중복합직물 방수시트 구조체와 이를 이용한 복합단열시트 방수공법에 관한 것이다.The present invention is a double composite fabric waterproof sheet structure having a thermal insulation performance and a composite insulation sheet waterproofing method using the same, more specifically solves the problem of deformation of the rubberized asphalt sheet according to the external temperature change, in particular excellent tensile strength and durability, elasticity Double layered composite fabric waterproof sheet made of polyester fiber, a synthetic fiber having high waterproof performance, and fiberglass, which is characterized by high strength, and an insulating nonwoven insulation sheet having excellent thermal insulation performance. The present invention relates to a composite fabric waterproof sheet structure and a composite insulating sheet waterproofing method using the same.
일반적으로 건축구조물의 옥상이나 상부 슬라브 등과 같은 콘크리트 구조물의 방수에 있어서 가장 광범위하고 전통적인 방수공법으로 도막방수공법 중에는 아크릴 수지와 또는 EVA수지를 이용하여 시멘트, 규사, 무기충전제와 기타 첨가제를 혼합하여 시공하는 무기질계 탄성도막 방수공법과 폴리에스테르와 폴리에테르에 이소시아네이트 등으로 고분자화한 폴리머에 여러 무기 충전제, 착색제를 혼합한 폴리우레탄 도막방수공법이 있다. Generally, it is the most extensive and traditional waterproofing method for waterproofing concrete structures such as rooftops or upper slabs of building structures. In coating waterproofing method, cement, silica sand, inorganic filler and other additives are mixed using acrylic resin or EVA resin. Inorganic elastic coating film waterproofing method and polyurethane coating film waterproofing method in which various inorganic fillers and coloring agents are mixed with a polymer polymerized with isocyanate or the like in polyester and polyether.
그리고 시트방수공법으로 가장 대표적으로 아스팔트를 유화시켜 합성고무를 배합시킨 고무화 아스팔트시트를 이용한 시공방법 등이 있는데 이러한 방법들의 경우, 먼저 도막방수에 있어서 요즘과 같이 불확실한 기후조건 속에서 시공기간이 장기간 길어지고 잦은 비로 인한 건조지연과 특히 공기 중에 수분과 습기에 취약한 폴리우레탄방수에 가장 큰 하자발생의 원인이 되는 경화반응불량이 나타나서 이로 인해 방수층과 방수층 사이에 접착성이 약해지는 문제점이 빈번하게 나타나고, 시공 후에 내구성약화와 들뜸현상과 박리사고의 원인이 되고 있다. 그리고 폴리우레탄 도막방수의 경우 주제와 경화제를 정해진 배합비로 현장에서 시공해야 하는 이유로 공정이 복잡해지고 현장작업자의 정확하지 않은 계량으로 혼합불량이 나타나서 본래의 물성이 나오지 않는 경우가 많고, 이 폴리우레탄 도막방수는 혼합하여 도포한 후 경화되어 방수기능을 갖는 도막을 형성하기까지 많은 시간이 걸린다. 시공초기단계에서는 액상의 형태로 유지되므로 일반적인 콘크리트 바닥에서는 완전한 수평이 아니기 때문에 도포 시 높은 곳에서 낮은 곳으로 흐름으로 인하여 일정한 두께의 도막을 형성하기 어려움으로 경화 후 얇은 층은 약한 외부 충격과 압력에 취약하여 도막파괴가 일어나 수회 시공과 보수를 해야 하는 문제점이 있다. The most popular method is the waterproofing method of rubberized asphalt sheets that emulsify asphalt and mixes synthetic rubber. In the case of these methods, the construction period is long in the climate of uncertain weather conditions. The delay in drying due to long and frequent rains and the hardening reactions that cause the greatest defects in polyurethane waterproof, which are particularly susceptible to moisture and moisture in the air, result in the weakening of adhesion between the waterproof layer and the waterproof layer. It is a cause of weakening of durability, lifting phenomenon and peeling after construction. In the case of waterproofing polyurethane coatings, the process is complicated due to the fact that the main body and the curing agent must be installed at a fixed mixing ratio, and inaccurate mixing due to inaccurate weighing of the field workers often results in the inherent physical properties. Waterproofing takes a long time to mix and apply, and then harden to form a coating having a waterproofing function. Since it is maintained in the form of liquid phase at the initial stage of construction, it is not completely horizontal on the general concrete floor, so it is difficult to form a coating film of a certain thickness due to flow from high to low during application. Due to fragile film breakdown, there is a problem that the construction and repair several times.
그리고 이러한 도막방수의 문제점을 보완하기 위해 시트공법이 있으나 대표적인 공법인 고무화 아스팔트시트공법의 경우 열에 의한 변형이 발생하며 이를 방지하기 위해 부직포를 합지하여 그 위에 중도층으로 무기질계 탄성도막방수나 폴리우레탄도막방수를 시공하고 상도층을 시공하고 있다. 하지만 공정횟수가 많아지고 인건비 지출이 증가되고 외부에 의한 열이 차단되지 않아 결국 직접 전달되는 열로 인해 변형이 되어 하자발생의 문제점이 되고 있다. And there is a sheet method to compensate for the problem of waterproofing the coating film, but the rubberized asphalt sheet method, which is a typical method, deformation occurs due to heat. In order to prevent this, the non-woven fabric is laminated and the inorganic elastic film waterproof or polyurethane is coated on it. The film is waterproofed and a top coat is being applied. However, as the number of processes increases, labor costs increase, and heat is not blocked by the outside, it is deformed due to heat transferred directly, which is a problem of occurrence of defects.
그리고 이와 같은 일반적인 도막방수공법과 시트방수공법의 대표적인 고무화 아스팔트시트방수공법의 경우에는 단열기능이 없기 때문에 건축물의 슬라브에 단열이 제대로 되어지지 않는 경우 여름 장마철이나 겨울철 실내에 외부와의 온도 차로 인해 결로 현상이 생겨 벽지가 젖고 곰팡이가 발생하고 있다.In the case of the typical rubberized asphalt sheet waterproofing method of the general coating film waterproofing method and sheet waterproofing method, there is no insulation function, so if the insulation of the slab of the building is not properly insulated due to the temperature difference between the outside in the summer rainy season or the winter season Condensation is occurring, the wallpaper is wet and mold is occurring.
그리고 일반적인 폴리우레탄도막방수의 경우 유기용제와 납, DOP와 같은 환경오염에 주범이 되는 화학 물질을 사용함으로 발생되는 문제점을 해결하기 위한 친환경적인 새로운 방수공법이 요구되고 있다.
In the case of general polyurethane coating waterproofing, there is a need for a new eco-friendly waterproofing method to solve the problems caused by the use of organic solvents, chemicals that lead to environmental pollution such as lead, DOP.
