[0015] In order to make the purpose, technical scheme and advantage of the embodiment of the utility model more clearly, the following will be combined with the drawing in the embodiment of the utility model, and the technical scheme in the embodiment of the utility model is clearly and completely described, obviously, the described embodiment is a part of the embodiment of the utility model, instead of all the embodiment. Based on the embodiment in the utility model, all other embodiments obtained by ordinary skilled person in the art without making creative labor belong to the scope of the utility model protection.

[0016] Please refer to Figure 1 The utility model provides a technical scheme: including prevent sticking layer 1, flame -retardant butyl adhesive self -adhesion layer 2, high polymer film base reinforcing layer 3, butyl adhesive self -adhesion layer 4, high polymer sheet waterproof layer 5 five layer structure of water -proof layer 5 from top to bottom in turn distribution, the length of prevent sticking layer 1 one side is less than the lap joint edge that forms with flame -retardant butyl adhesive self -adhesion layer 2, and its lap joint edge width is 8-10cm.

[0017] It should be noted that the 8-10cm lap joint edge set between the prevent sticking layer 1 and the flame -retardant butyl adhesive self -adhesion layer 2 can effectively prevent moisture from penetrating from the joint of the roll material. The 8-10cm lap joint width is wide enough to ensure the sealing of the joint, thereby greatly enhancing the overall waterproof performance of the roll material. During construction, the construction personnel can more easily control and adjust the laying position of the roll material, ensuring the accurate lap joint between the roll materials. This design simplifies the construction steps, improves the construction efficiency, and reduces the risk of water leakage due to improper operation. The existence of the lap joint edge makes the roll materials form a more stable connection, thereby enhancing the overall stability of the roll materials. When subjected to external forces, such as base settlement or wind force, the roll materials can better resist deformation and displacement, maintaining the integrity of their waterproof function. In complex base surface environments, such as areas with unevenness or irregular shapes, the 8-10cm lap joint edge can more effectively adapt to these changes, ensuring that the roll materials can closely adhere to the base layer and form an effective waterproof layer.

[0018] Further, the prevent sticking layer 1 is composed of reactive sand, and the fineness is 30-60 mesh.

[0019] The prevent sticking layer 1 is composed of reactive sand, and the fineness is 30-60 mesh. The reactive sand has good anti-sticking performance and certain roughness, which helps the roll material closely adhere to the base layer during construction and prevents the roll material from sticking to itself. This improves the construction efficiency and quality of the roll material, reducing waste and damage caused by self-sticking of the roll material.

[0020] Further, the flame -retardant butyl adhesive self -adhesion layer 2 is composed of butyl rubber, petroleum resin and flame retardant, and the thickness is 0.25-0.3mm.

This combination of materials has excellent flame -retardant performance and self -adhesion, and can maintain stable performance in high temperature environment. Effectively improve the flame -retardant performance of the roll material, reduce the risk of roll material burning caused by high temperature factors such as electric slag, and ensure the close adhesion of the roll material to the base layer.

[0022] Further, the high polymer film base reinforcing layer 3 is composed of four layers of laminated cross film, and the thickness is 0.1-0.2mm, and the tension is ≥300N / 5cm.

[0023] The high polymer film base reinforcing layer 3 is composed of four layers of laminated cross film, with a thickness of 0.1-0.2mm and a tensile force of ≥300N / 5cm. The high polymer film with this structure has high strength and good ductility, which can effectively resist the pressure caused by the settlement deformation of the base layer. The strength and durability of the roll material are significantly improved, the problem of roll material rupture caused by the settlement deformation of the base layer is avoided, and the long-term effect of the waterproof engineering is ensured.

[0024] Further, the butyl rubber self-adhesive layer 4 is made of butyl rubber and petroleum resin, with a thickness of 0.25-0.3mm.

[0025] The butyl rubber self-adhesive layer 4 is composed of butyl rubber and petroleum resin, with a thickness of 0.25-0.3mm. This material has good self-adhesion and sealing properties, which can ensure the close fit between the layers of the roll material. The overall performance and waterproof effect of the roll material are improved, and the risk of water leakage caused by separation between the layers of the roll material is reduced.

[0026] Further, the high polymer sheet waterproof layer is composed of linear low-density polyethylene and additives, with a thickness of 0.7-0.9mm.

[0027] The high polymer sheet waterproof layer 5 is composed of linear low-density polyethylene and additives, with a thickness of 0.7-0.9mm. Linear low-density polyethylene has good softness and processing performance, while maintaining sufficient strength and durability. While ensuring the softness and ease of construction of the roll material, the strength and waterproof performance of the roll material are also ensured, effectively avoiding the problem of roll material rupture caused by the settlement deformation of the base layer.
