[0022] Preferred embodiments of the present invention will now be described in more detail. While 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 to the embodiments set forth herein. Rather, 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.

[0023] like Figure 1 As shown, this utility model provides a waterproof membrane, comprising:

[0024] The structure consists of a lower isolation layer 1, a lower waterproof layer 2, a base layer 3, an upper waterproof layer 4, and an upper isolation layer 5, arranged sequentially from bottom to top. The materials of the lower waterproof layer 2 and the upper waterproof layer 4 are carbon fiber modified asphalt.

[0025] Specifically, to address the shortcomings of existing SBS modified bitumen waterproof membranes in terms of strength, toughness, and low-temperature resistance, the waterproof membrane provided by this invention has a lower waterproof layer 2 and an upper waterproof layer 4 made of carbon fiber modified bitumen respectively on the lower and upper sides of the base layer 3. While providing sufficient waterproofing effect, the use of carbon fiber modified bitumen layers as the lower waterproof layer 2 and upper waterproof layer 4 can significantly improve the strength, toughness, and low-temperature resistance of the waterproof membrane. At the same time, the lower isolation layer 1 and the upper isolation layer 5 provide isolation effect on both outer sides of the waterproof membrane.

[0026] Optionally, the base layer 3 is made of polyester.

[0027] Specifically, the base layer 3 can be made of polyester base, which can be a long-fiber polyester base with a weight of 200g / ㎡ and a thickness of 0.9mm; the lower waterproof layer 2 and the upper waterproof layer 4 can be coated on the polyester base layer 3 after drying, oiling and squeezing, and then the lower isolation layer 1 and the upper isolation layer 5 are covered on the surface.

[0028] Optionally, the base layer 3 is made of carbon fiber reinforced polyester.

[0029] Specifically, the base layer 3 can also use carbon fiber reinforced polyester base. A carbon fiber reinforced polyester base with a weight of 200-300g / ㎡ and a thickness of 0.5-0.6mm can be selected, which is about half the thickness of the conventional polyester base. This forms an ultra-strong, ultra-tough, and ultra-thin base layer 3. The selection of such a base layer 3 can improve the physical and mechanical properties of the waterproof membrane while keeping the thickness of the waterproof membrane at the conventional 3mm, so as to fill as much of the lower waterproof layer 2 and upper waterproof layer 4 material as possible, thereby improving the waterproof quality and waterproof life of the waterproof membrane.

[0030] Optionally, the thickness of the base layer 3 is 0.5-0.6 mm.

[0031] Specifically, the thickness of the base layer 3 made of carbon fiber reinforced polyester material can be very thin, reducing its thickness while maintaining good strength performance. Under the same waterproof membrane thickness, the waterproof membrane has a higher content of carbon fiber modified bitumen, which is beneficial to the waterproof quality and waterproof life of the waterproof membrane.

[0032] Optionally, the material of the lower isolation layer 1 is an isolation membrane.

[0033] Specifically, the lower isolation layer 1 can be a conventional isolation film, such as a PE isolation film.

[0034] Optionally, the material of the lower isolation layer 1 is carbon fiber cloth.

[0035] Specifically, the lower isolation layer 1 can also be made of carbon fiber cloth, which can be selected with a weight of 200-300g / ㎡ and a thickness of 0.1-0.2mm, and covered on the surface of the lower waterproof layer 2. Using the carbon fiber cloth layer as the lower isolation layer 1, the carbon fiber cloth is bonded to the area to be repaired through the matching adhesive. The carbon fiber cloth is used to reinforce the structure of the area to be repaired, while combining the waterproof effect of the carbon fiber modified bitumen covering material of the lower waterproof layer 2. Furthermore, the carbon fiber modified bitumen material can protect the carbon fiber cloth, making it more durable.

[0036] Optionally, the thickness of the lower isolation layer 1 is 0.1-0.2 mm.

[0037] Specifically, carbon fiber cloth is used as the lower isolation layer 1, and its thickness can be very thin.

[0038] Optionally, the upper isolation layer 5 is made of PE film.

[0039] Specifically, the upper isolation layer 5 can be made of PE film.

[0040] Optionally, the upper isolation layer 5 may be made of shale.

[0041] Specifically, the upper isolation layer 5 can also be made of shale and can be exposed.

[0042] Optionally, the thickness of the waterproof membrane is 3mm.

[0043] Specifically, the thickness of this waterproof membrane can be made like that of conventional SBS modified bitumen waterproof membrane, at 3mm.
