Technical Field

[0001] The present application relates to the technical field of waterproofing membranes, and in particular to an APP modified asphalt waterproofing membrane. Background Art

[0002] Waterproof membrane is a kind of flexible building material product that can be rolled into a roll and mainly serves to resist the leakage of external rain and groundwater. It is widely used in building walls, roofs, tunnels and roads. As a leak-free connection between the project foundation and the building, it is the first barrier to waterproofing the entire project and plays a vital role in the entire project.

[0003] The waterproof membrane laid on the roof is often exposed to the sun, so the ultraviolet rays in the sun can easily accelerate the aging of the waterproof membrane and shorten the service life of the waterproof membrane. Utility Model Content

[0013] By adopting the above technical solution, the aerogel felt layer has a strong heat insulation effect, thus helping to enhance the high temperature resistance of the coil body.

[0014] Optionally, the coil body includes a first waterproof membrane layer, a first asphalt layer, a base material layer, a second asphalt layer and a second waterproof membrane layer which are arranged in sequence.

[0015] By adopting the above technical solution, the first waterproof membrane layer and the second waterproof membrane layer can play a waterproof role, and the first asphalt layer and the second asphalt layer are APP modified asphalt layers, so that the waterproof membrane has better high temperature resistance.

[0016] Optionally, a PE waterproof layer is provided between the first waterproof membrane layer and the first asphalt layer.

[0017] By adopting the above technical solution, the waterproof performance of the coiled material body can be further improved.

[0018] Optionally, a marking line is provided on a side of the aluminum foil layer away from the anti-ultraviolet fiber layer.

[0021] By adopting the above technical solution, after overlapping adjacent waterproof membranes, it helps to ensure the consistency of the overlapping width, thereby ensuring the waterproof effect of the overlapping joint.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0028] The present application is further described in detail below in conjunction with the accompanying drawings.

[0029] The present application discloses an APP modified asphalt waterproofing membrane. Figure 1 The APP modified asphalt waterproofing membrane comprises a membrane body 1, which comprises a first waterproof membrane layer 11, a first asphalt layer 12, a base material layer 13, a second asphalt layer 14 and a second waterproof membrane layer 15 which are sequentially bonded and fixed. The first waterproof membrane layer 11 and the second waterproof membrane layer 15 are both PVC waterproof membranes. The first asphalt layer 12 and the second asphalt layer 14 are both APP modified asphalt layers, and thus have good high temperature resistance. The base material layer 13 is a glass fiber layer.

[0030] A PE waterproof layer 6 is bonded between the first waterproof membrane layer 11 and the first asphalt layer 12 , and a PE waterproof layer 6 is also bonded between the second waterproof membrane layer 15 and the second asphalt layer 14 . The provision of the PE waterproof layer 6 can further enhance the waterproof performance.

[0031] An aerogel felt layer 5 is bonded to the outside of one of the first waterproof membrane layers 11. The aerogel felt is a flexible thermal insulation felt made of nano-silicon dioxide aerogel as the main material and is compounded with glass fiber wool or pre-oxidized fiber felt through a special process. The thermal conductivity of the aerogel felt is low, so it can further enhance the high temperature resistance of the waterproof membrane.

[0032] The aerogel felt layer 5 is bonded with an anti-ultraviolet fiber layer 2 on one side away from the first waterproof membrane layer 11. The anti-ultraviolet fiber layer 2 is made of acrylic fiber, which is an excellent anti-ultraviolet fiber. It can absorb ultraviolet energy and convert it into heat energy and dissipate it, so very little energy is conducted to the fiber, which can play a role in anti-ultraviolet.

[0033] Furthermore, the anti-ultraviolet fiber layer 2 is provided with two layers, and the two anti-ultraviolet fiber layers 2 are arranged in parallel at intervals, so that a cavity is formed between the two anti-ultraviolet fiber layers 2, and air is stored in the cavity. The thermal conductivity of air is small, so it helps to enhance the high temperature resistance of the waterproof coiled material; the outer edges of the two anti-ultraviolet fiber layers 2 are bonded and fixed to prevent moisture from entering the cavity and ensure the waterproof effect. The two anti-ultraviolet fiber layers 2 are fixedly bonded on one side close to each other, and there are multiple protrusions 4 on the same anti-ultraviolet fiber layer 2, and they are arranged in an array; the protrusions 4 are hemispherical, and the two sides of the protrusions 4 are respectively against the two anti-ultraviolet fiber layers 2, so the protrusions 4 can play a supporting role.

[0034] The bump 4 is also coated with an ultraviolet absorber coating 41. The ultraviolet absorber is a salicylic acid-based agent that can form stable hydrogen bonds. The hydrogen bond integration ring can absorb energy and convert it into heat energy and dissipate it, so very little energy is conducted to the polymer, which plays a role in preventing ultraviolet rays. In other embodiments, the ultraviolet absorber can also be a benzophenone-based agent, a benzotriazole-based agent, a cyanoacrylate-based agent, and the like.

[0035] An aluminum foil layer 3 is also bonded to the outer side of the anti-ultraviolet fiber layer 2 away from the first waterproof membrane layer 11 . The aluminum foil layer 3 can reflect sunlight, thereby reducing the ultraviolet rays entering the coil body 1 and weakening the impact of ultraviolet rays on the coil body 1 .

[0036] Reference Figure 2 A marking line 31 is provided on one side of the aluminum foil layer 3 away from the anti-ultraviolet fiber layer 2, and the marking line 31 is provided along the length direction of the aluminum foil layer 3. The marking line 31 can serve as a marking function, so that construction personnel can distinguish the upper and lower sides of the waterproof coiled material.

[0037] Furthermore, two marking lines 31 are provided, and the two marking lines 31 are respectively located at the two edges in the width direction of the aluminum foil layer 3. The distance between the edge of the aluminum foil layer 3 close to the marking line 31 and the corresponding marking line 31 is 10 cm. Therefore, when laying the waterproof membrane, aligning the marking lines 31 on one of the waterproof membranes with the adjacent waterproof membrane can ensure the uniformity of the overlap width, thereby ensuring the laying effect of the waterproof membrane.

[0038] The implementation principle of an APP modified asphalt waterproofing membrane in the embodiment of the present application is as follows: the waterproofing membrane is laid on the roof so that the side edge of one of the waterproofing membranes is aligned with the marking line 31 on the adjacent waterproofing membrane, so that the waterproofing membrane is laid flat. After laying, the second waterproofing membrane layer 15 is located at the bottom, and the second waterproofing membrane layer 15 is against the roof, and the aluminum foil layer 3 is located at the top. When sunlight shines on the aluminum foil layer 3, the aluminum foil layer 3 will reflect part of the sunlight, and the other part of the sunlight that passes through the aluminum foil layer 3 will shine on the anti-ultraviolet fiber layer 2. The ultraviolet absorber coating 41 on the anti-ultraviolet fiber layer 2 and the protrusion 4 can absorb ultraviolet rays in the sunlight, thereby reducing the influence of ultraviolet rays on the waterproofing membrane and slowing down the aging rate of the waterproofing membrane.

[0039] The above are optional embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
