Abstract

The invention relates to a modified asphalt waterproof coiled material with reinforced overlap edges and a production method of the modified asphalt waterproof coiled material. The modified asphalt waterproof coiled material comprises a main body material layer, a modified asphalt layer and an isolating membrane, wherein two strips of fiber cloth are respectively embedded between the parts, which are respectively 0.1-1cm away from the edges of the two sides along the longitudinal direction of the modified asphalt layer, and the isolating membrane, so that the overlap edges are formed. After the method is adopted, the mechanical properties of the overlap edges are obviously improved after the modified asphalt waterproof coiled material is molded, so that the water resistance of the modified asphalt waterproof coiled material is more reliable; the production method provided by the invention solves the problems that in the traditional production process, due to mechanical mismatch of the left side and the right side of the coiled material, the coiled material is neat when being coiled and is twisted when being unfolded, and the like, and improves the quality of the waterproof coiled material.

Description

technical field [0001] The invention relates to a production method for reinforcing the overlapping edge of modified asphalt waterproof coiled materials, and belongs to the field of building waterproof construction. Background technique [0002] At present, the waterproof membrane adopts grid cloth in the way of adding grid cloth to the whole and adding grid cloth to one side, which increases the strength of the membrane to a certain extent, but also receives some restrictions. After the mesh fiber is added as a whole between the main material and the modified asphalt layer, the tensile strength of the coil is greatly enhanced, but the ductility is limited, because the fiber mesh, especially the stripped fiber mesh, The tensile strength is very high, but the ductility is very small when subjected to the maximum tensile force. Once the external stress on the coil is greater than its own strength, it cannot be effectively stretched to resist the stress, which will cause the co...
