[0002] China's construction industry is developing rapidly, with the current construction area exceeding 70 billion square meters. However, due to different construction technology standards and construction levels in different eras and the aging of buildings, an average of about 2 billion square meters of buildings need to be repaired every year in recent years. The repair work faces a complex environment, which puts higher requirements on the ability of waterproof membranes to resist external damage.
[0003] Based on the thickness of the waterproof membrane, the design and construction of its overlap edge is an important part of ensuring its waterproof function. Optimizing the product structure at the overlap is the key to ensuring the effective sealing of the waterproof structure.
[0004] The soluble matter content refers to the content of organic substances such as asphalt and SBS thermoplastic elastomer in the waterproof membrane, that is, the content of key substances that make the waterproof membrane play a "waterproof" role. Increasing the soluble matter content is an effective measure to ensure the waterproof effect. Utility Model Content

[0016] Optionally, the width of the first single tire area is 30-100 mm, and the width of the second single tire area is 10-50 mm.
[0017] The utility model provides a waterproof coiled material, which has the beneficial effects that: the waterproof coiled material has two tread layers, a first tread layer and a second tread layer, which can improve the puncture resistance, maximum tolerable tensile force, thermal aging dimensional change, etc. of the waterproof coiled material, and can improve the ability of the waterproof coiled material to resist external damage.

[0023] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.
[0024] like Figure 1 As shown, the utility model provides a waterproof coiled material, comprising:
[0025] A first waterproof layer 1, a first tread base layer 2, a second waterproof layer 3, a second tread base layer 4 and a third waterproof layer 5 are arranged in sequence, one end of the waterproof roll in the width direction is an overlap edge 10, the width of the second tread base layer 4 is smaller than the width of the first tread base layer 2, a first single tire area 6 is formed on the side of the second tread base layer 4 close to the overlap edge 10, and a second single tire area 7 is formed on the side of the second tread base layer 4 away from the overlap edge 10, and the third waterproof layer 5 and the second waterproof layer 3 wrap the second tread base layer 4.
[0026] Specifically, in order to comprehensively consider the ability of the waterproof membrane to resist external damage, the overlapping effect of the overlapping edge 10 and the improvement of the soluble content, the overall performance of the waterproof membrane is comprehensively improved; the waterproof membrane provided by the utility model has two tread layers, a first tread layer 2 and a second tread layer 4, which can improve the puncture resistance, maximum tolerable tensile force, thermal aging dimensional change, etc. of the waterproof membrane, and can improve the ability of the waterproof membrane to resist external damage. The first tread layer 2 and the second tread layer 4 are laminated and clamped by the first waterproof layer 1, the second waterproof layer 3 and the third waterproof layer 5, and the width of the second tread layer 4 is smaller than that of the first tread layer 2, the second tread base layer 4 is wrapped by the second waterproof layer 3 and the third waterproof layer 5, and the first single tire area 6 and the second single tire area 7 are respectively formed on the side of the second tread base layer 4 close to the overlapping edge 10 and the side away from the overlapping edge 10, that is, the first single tire area 6 and the second single tire area 7 both have only one first tread base layer 2 and no second tread base layer 4. Such an arrangement can not only increase the content of the waterproof layer, but also increase the soluble matter content, and can reduce the thickness of the tread base at the overlapping parts on both sides in the width direction, so as to better realize the airtightness of the waterproof layer and reduce the risk of leakage at the weak link, i.e., the overlapping parts.
[0027] Furthermore, in order to fully consider the hidden dangers of the overlap edge 10 of the double-base waterproof membrane being too hard or too thick, causing the overlap edge 10 to warp and be difficult to press, etc. due to the double-base design, the waterproof membrane provided by the utility model has an innovative structural design to achieve a large-area double-base structure with a single-base in the overlap area.
[0028] In this embodiment, the width of the first single tire area 6 is 30-100mm, the width of the second single tire area 7 is 10-50mm, and the overall thickness of the single tire area is still ≥5mm, which can ensure that the overlap edge 10 has stronger conformity, more modified asphalt material, and better edge sealing overlap effect; the overlap edge 10 can be impermeable to 1.0MPa, which is more than 3 times the conventional national standard indicator.
[0029] Optionally, the materials of the first waterproof layer 1 , the second waterproof layer 3 and the third waterproof layer 5 are modified asphalt or SBS thermoplastic elastomer.
[0030] Specifically, the organic substances in the materials of the first waterproof layer 1, the second waterproof layer 3 and the third waterproof layer 5 are the key substances that enable the waterproof membrane to play a "waterproof" role, and the content of such organic substances can be referred to as soluble content.
[0031] In this embodiment, the modified asphalt materials of the first waterproof layer 1, the second waterproof layer 3 and the third waterproof layer 5 are all modified asphalt coating materials that are modified by conventional modification methods in the industry and meet national standards.
[0032] Optionally, the first tread base layer 2 is a long-fiber polyester tread base.
[0033] Specifically, the first tire base layer 2 adopts a long-fiber polyester tire base, which can be directly purchased from outside and can be used as the "main skeleton" of the double tire base structure to ensure the product's tensile strength, elongation, puncture resistance, and construction cut resistance.
[0034] Optionally, the second tread base layer 4 is an inorganic glass fiber reinforced polyester fiber tread base.
[0035] Specifically, the second tread base layer 4 adopts an inorganic glass fiber reinforced polyester fiber base, that is, a glass fiber reinforced polyester base, which can be directly purchased from outside. The thickness of the second tread base layer 4 is less than the thickness of the first tread base layer 2. Compared with using two identical first tread base layers 2, it can reduce the overall thickness of the tread base layer, increase the specific gravity of the modified asphalt of the waterproof membrane, and at the same time increase the soluble content, which can improve the waterproof effect and waterproof life.
[0036] Optionally, the first tread layer 2 has a gram weight of 200-250 g / ㎡.
[0037] Optionally, the thickness of the first tread layer 2 is 0.9-1.2 mm.
[0038] Optionally, the second tread layer 4 has a gram weight of 40-80 g / ㎡.
[0039] Optionally, the thickness of the second tread layer 4 is 0.2-0.6 mm.
[0040] In this embodiment, the structural design of the waterproof membrane introduces an ultra-thin and ultra-tough base, namely, the second base layer 4, with a thickness of 0.2-0.6 mm. The thickness of the second base layer 4 is 1 / 3 of the thickness of a conventional polyester base, combined with a conventional long-fiber polyester base, namely, the first base layer 2, with a thickness of 0.9-1.2 mm. The introduction of the ultra-thin and ultra-tough base can increase the proportion of modified asphalt in the waterproof membrane, thereby increasing the waterproof effect and waterproof life. The soluble content can be made ≥3500 g / ㎡, which is 65% higher than that of conventional SBS3mm waterproof membranes, and its larger oil output is more conducive to sealing and bonding.
[0041] Optionally, a first isolation layer 8 is provided on a side of the first waterproof layer 1 away from the second waterproof layer 3 , and a second isolation layer 9 is provided on a side of the third waterproof layer 5 away from the second waterproof layer 3 .
[0042] Specifically, the first isolation layer 8 may be an isolation film, and the second isolation layer 9 may be a polyethylene film or shale.
[0043] In this embodiment, the overlapping edge 10 does not have the second isolation layer 9 , and a release film may be provided to cover the overlapping edge 10 .
[0044] Optionally, the width of the first single tire area 6 is 30-100 mm, and the width of the second single tire area 7 is 10-50 mm.
[0045] In this embodiment, the first waterproof layer 1, the first tread base layer 2, the second waterproof layer 3, the second tread base layer 4 and the third waterproof layer 5 are arranged in sequence from bottom to top, the first waterproof layer 1 is the lower waterproof layer, the first tread base layer 2 is the lower tread base layer, the second waterproof layer 3 is the middle waterproof layer, the second tread base layer 4 is the upper tread base layer, and the third waterproof layer 5 is the upper waterproof layer.
[0046] In summary, the waterproof roll material provided by the utility model is prepared by taking one production as an example:
[0047] The "double drying, double pre-impregnation, double squeezing" method is adopted to respectively coat the configured upper waterproof layer, lower waterproof layer and middle waterproof layer of polymer modified asphalt on the two base layers after drying, oil impregnation and squeezing. The upper base layer uses a glass fiber reinforced polyester base with a gram weight of 50g / ㎡ and a thickness of 0.3mm, and the lower base layer uses a long-fiber polyester fiber base with a gram weight of 200g / ㎡ and a thickness of 0.9mm. Then the upper surface is covered with a polyethylene film, and the coating material is covered with a polyethylene film on the lower surface after a cooling process. After finalizing and winding, the waterproof membrane is obtained.
[0048] The waterproof coiled material provided by the utility model can be used for roof repair. In this case, the second isolation layer 9 can also be made of shale or inorganic mineral granules, which can enhance the anti-ultraviolet effect of the surface of the waterproof coiled material.
[0049] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
