In addition, the waterproof roll material of the embodiment of the present application is provided with a first connecting part and a second connecting part at both ends of the main waterproof area, so that the first reinforcement layer of the fourth splicing part of one waterproof roll material is connected to the adhesive layer of the second splicing part of another waterproof roll material, and the third splicing part can be overlapped on the first splicing adhesive layer of the second splicing part, and finally the second reinforcement layer of the first splicing part is overlapped with the second reinforcement layer of the third splicing part, so as to have a structure that realizes multi-layer bite, strengthen the connection strength of the overlapping parts of the waterproof roll material, and reduce the risk of water leakage.

[0046] In the embodiments of the present application, Figure 1As shown, the first splicing adhesive layer 15 covers the side of the first reinforcement layer 12 in the second splicing part 22 away from the adhesive layer 11.

[0047] In the embodiments of the present application, Figure 1-6 As shown, the surface material layer 14 of the first splicing part 21 in the first connecting part 2 is connected to the surface material layer 14 of the main waterproof area 1, and can be integrally formed or separately arranged.

The first splicing adhesive layer 15 and the adhesive layer 11 can both infiltrate the hooking fluff layer 8 and strengthen the connection strength with the second splicing part 22, thereby improving the waterproof performance of the waterproof roll material. The difference between the hooking fluff layer 9 and the fluff layer 8 is that the fluff of the hooking fluff layer 9 is arc-shaped or hook-shaped at the end of the second reinforcing layer away from the third splicing part or at the end of the first reinforcing layer away from the fourth splicing part, so as to better bond with the adhesive layer or the first splicing adhesive layer.

[0067] In some embodiments, the material of the surface material layer is selected from shale, reactive sand, mineral particles, TPO, HDPE, PVC, PE film, PP film, PET film, PET aluminized film, PVDF film, PF film, silicon titanium film, aluminum foil composite film, stainless steel film, polymer fiber cloth. The surface material layer can well protect the first reinforcement layer, the second reinforcement layer and the adhesive layer of the waterproof coiled material, as well as the middle adhesive layer and the outer adhesive layer, and prevent the main waterproof structure layer of the waterproof coiled material from being affected by external light and debris.

[0068] In some embodiments of the present application, the first reinforcement layer is selected from polyethylene polypropylene composite waterproof membrane, polymer reinforced composite waterproof sheet, thermoplastic polyolefin waterproof membrane, elastomer modified asphalt waterproof membrane, and plastomer modified asphalt waterproof membrane.

[0069] In some embodiments of the present application, the second reinforcement layer is selected from polyethylene polypropylene composite waterproof membrane, polymer reinforced composite waterproof sheet, thermoplastic polyolefin waterproof membrane, elastomer modified asphalt waterproof membrane, and plastomer modified asphalt waterproof membrane.

[0070] In some embodiments of the present application, the adhesive layer is selected from butyl adhesive, self-adhesive adhesive, hot melt adhesive, asphalt self-adhesive adhesive, and hot melt elastomer pressure-sensitive adhesive.

[0072] In some embodiments of the present application, the adhesive layer 11 of the second splicing portion 22, the main waterproof area 1, and the fourth splicing portion 32 are integrally connected and are all arranged on the side of the first reinforcement layer 12 away from the second reinforcement layer 13, so that the adhesive layer is unilaterally arranged in the waterproof membrane, which facilitates the laying of the waterproof membrane on the surface of the structure to be constructed and enables a good connection between two adjacent waterproof membranes.

[0073] The waterproofing coiled material of the embodiment of the present application is used. The first reinforcement layer and the second reinforcement layer of the waterproofing coiled material are combined as a double reinforcement layer. By laying a layer of the waterproofing coiled material of the embodiment of the present application, the effect of two layers of waterproofing coiled materials can be achieved, and the requirements of waterproofing specifications are met. The waterproofing coiled material has a self-adhesive layer on one side. After tearing off the isolation layer, it can be directly pasted on the surface of the structural base that needs to be waterproofed. The construction is convenient and simple, which can effectively save the construction period and improve the construction efficiency. The first connecting part and the second connecting part of the waterproofing coiled material are connected by a multi-layer bite overlap method, and can be further connected by gluing and welding overlap methods. The connection parts of the waterproofing coiled material have double connection guarantees, which doubles the connection strength of the overlapped parts, strengthens the connection strength of the connection parts of the waterproofing coiled material, and avoids displacement after the coiled material is constructed.
