INTEGRATED COMPOSITE WATERPROOF LAYER AND METHOD OF INTEGRATED COMPOSITE WATERPROOF CONSTRUCTION
Provided in the present invention is an integrated composite waterproof construction method which attaches a waterproof sheet, formed by attaching non-woven fabric where an amine compound is coated on the bottom surface or both the top surface and the bottom surface, i) onto a solvent-free urethane waterproof material and ii) in the lower part of a modified asphalt compound. The construction method can form an integrated composite waterproof layer through chemical bond between the waterproof material and the waterproof sheet due to urea reaction between polyisocyanate contained in the waterproof material and the amine compound coated on the non-woven fabric. Therefore, the construction method can improve bonding strength by integrating the waterproof material with the waterproof sheet through chemical bond, and can remove a problem of waterproof function degradation of a joint unit by attaching the waterproof sheet to overlap an adjacent waterproof sheet and filling the waterproof material into the joint unit between the overlapping two waterproof sheets. In addition, the construction method can significantly reduce construction time compared with the conventional method by coating the waterproof material at the same time as attaching the waterproof sheet and, in turn, skipping steps of drying and curing of the waterproof material.
본 발명은 ⅰ)무용제 우레탄계 방수재 위에, ⅱ)개량아스팔트 콤파운드의 하부에, 하부면 또는 상부면과 하부면 모두에 아민계 화합물이 코팅된 부직포가 부착되어 형성된 방수시트를 부착하는 방법으로서, 방수재에 포함된 폴리이소시아네이트와 부직포에 코팅된 아민계 화합물 간의 우레아 반응에 의해 방수재와 방수시트 간의 화학적 결합이 이루어져 일체화된 복합방수층을 형성하는 일체화 복합방수 시공방법을 제공한다. 이로써, 방수재와 방수시트 간의 화학적 결합으로 인하여 방수재와 방수시트가 일체화되어 접착강도를 향상시킬 수 있으며, 방수시트를 인접한 방수시트와 중첩되게 부착하고 중첩된 두 방수시트 간의 이음부에 방수재가 충진되도록 함으로써 이음부의 방수성능 저하 문제를 개선시킬 수 있다. 또한 방수재를 도포함과 동시에 방수시트를 부착할 수 있어, 방수재의 건조와 양생단계를 거치지 않아 종래의 시공방법보다 시공시간이 획기적으로 단축할 수 있는 효과가 있다.
