The waterproof coiled material products in the current market mainly comprise asphalt waterproof coiled materials and high-molecular waterproof coiled materials. The asphalt waterproof coiled material is a curlable sheet waterproof material which is prepared by dipping asphalt on a base (such as base paper and fiber fabric) and then spreading powdery or sheet isolating material on the surface.
The traditional asphalt waterproof coiled material is a single-base modified asphalt waterproof coiled material, the tensile strength and the tearing strength of the traditional asphalt waterproof coiled material are relatively low, and the single-base modified asphalt waterproof coiled material cannot meet the use requirement when meeting the severe environment or meeting the waterproof coiled material of a special part in a building. Later, a double-base asphalt waterproof coiled material is developed, for example, a self-adhesive waterproof coiled material disclosed in chinese patent CN202866011U, which comprises an upper surface material, a lower surface material, a first layer of self-adhesive asphalt coating material, a second layer of self-adhesive asphalt coating material, a third layer of self-adhesive asphalt coating material, a first base reinforcing layer and a second base reinforcing layer, wherein the first layer of self-adhesive asphalt coating material is arranged between the lower surface material and the first base reinforcing layer, the second layer of self-adhesive asphalt coating material is arranged between the first base reinforcing layer and the second base reinforcing layer, and the third layer of self-adhesive asphalt coating material is arranged between the second base reinforcing layer and the upper surface material. The self-adhesive waterproof coiled material is compounded by the double-layer base, so that the strength of the coiled material is greatly improved. However, the upper surface material is plastic film, fine sand or isolation film, and the lower surface material is fine sand, isolation film or isolation paper, so that the waterproof roll is easy to damage in the specific construction process, poor in cohesiveness with post-cast concrete or needs to be stripped off when the concrete is post-cast, and the waterproof roll adopting fine sand is low in yield, heavy and easy to fall off.
