Description

Technical Field

[0001] The utility model relates to the technical field of SBS waterproof coiled materials, in particular to an SBS waterproof coiled material. Background Art

[0002] The SBS waterproof coiled material is made by using SBS synthetic rubber as the base material of modified asphalt, adding high-strength polypropylene fibers and special additives, and has relatively good weather resistance and corrosion resistance, and can be used for waterproof projects such as building roofs, basements, underground tunnels, and water conservancy projects.

[0003] The inventor found in the actual application process that when laying the SBS waterproof coiled material, the connection at the gap between adjacent waterproof coiled materials is not tight enough, resulting in water seepage and leakage problems. Therefore, we propose an SBS waterproof coiled material. Summary of the Utility Model

[0004] In order to overcome the defects of the prior art pointed out above, the inventor has conducted in-depth research and completed the present utility model after a large amount of creative labor.

[0005] Specifically, the technical problem to be solved by the present utility model is: to provide an SBS waterproof coiled material to solve the technical problems of insufficient tight connection at the gap between adjacent waterproof coiled materials and water seepage and leakage.

[0006] To solve the above technical problems, the present utility model provides the following technical solution:

[0007] An SBS waterproof coiled material, comprising: an SBS waterproof coiled material;

[0008] A notch, which is provided at the upper and lower ends of one side of the SBS waterproof coiled material and forms a protrusion for overlapping adjacent SBS waterproof coiled materials;

[0009] A groove, which is provided in the middle of the other side of the SBS waterproof coiled material. The groove is melt-bonded to and fits with the protrusion, and is used for overlapping adjacent SBS waterproof coiled materials. By placing the protrusion on the adjacent SBS waterproof coiled material into the groove on the adjacent SBS waterproof coiled material and then performing melt-bonding, the tight connection at the gap between adjacent SBS waterproof coiled materials can be completed, thereby ensuring the tight connection at the gap between adjacent waterproof coiled materials and preventing water seepage and leakage.

[0010] As an improved technical solution, the outer surface shape and size of the protrusion are both adapted to the inner cavity shape and size of the groove.

[0011] As an improved technical solution, the SBS waterproof coiled material includes a carcass substrate, puncture-proof structures are provided on both the upper and lower sides of the carcass substrate, modified asphalt adhesive layers are provided on both the upper and lower sides of the puncture-proof structures, and release layers are provided on both the upper and lower sides of the modified asphalt adhesive layers.

[0012] As an improved technical solution, the puncture-proof structure includes a first puncture-proof layer provided on both sides of the carcass substrate, a second puncture-proof layer is provided on the first puncture-proof layer, and one side of the second puncture-proof layer away from the first puncture-proof layer is connected to the modified asphalt adhesive layer. By peeling off the release layer on the SBS waterproof coiled material and bonding the modified asphalt adhesive layer to the building object, the first puncture-proof layer and the second puncture-proof layer sequentially arranged on both the upper and lower sides of the carcass substrate can prevent sharp objects from piercing the carcass substrate. With the above structure, it is convenient to improve the puncture-proof effect of the SBS waterproof coiled material, and further avoid the phenomenon that the SBS waterproof coiled material is pierced by force collision or sharp objects.

[0013] As an improved technical solution, the thickness of the second puncture-proof layer is twice the thickness of the first puncture-proof layer.

[0014] As an improved technical solution, the first puncture-proof layer is made of polyester, and the second puncture-proof layer is made of a high molecular elastomer.

[0015] As an improved technical solution, the thickness of the modified asphalt adhesive layer is equal to the thickness of the first puncture-proof layer.

[0016] As an improved technical solution, the thickness of the carcass substrate is greater than the thickness of the second puncture-proof layer.

[0017] After adopting the above technical solution, the beneficial effects of the present utility model are:

[0018] 1. In the present utility model, by placing the protrusions on adjacent SBS waterproof coiled materials into the grooves on adjacent SBS waterproof coiled materials and then performing melting bonding, the tight connection at the gaps between adjacent SBS waterproof coiled materials can be completed, thereby ensuring the tight connection at the gaps between adjacent waterproof coiled materials, and further preventing water seepage and leakage.

[0019] 2. In the present utility model, by peeling off the release layer on the SBS waterproof coiled material and bonding the modified asphalt adhesive layer to the building object, the first puncture-proof layer and the second puncture-proof layer sequentially arranged on both the upper and lower sides of the carcass substrate can prevent sharp objects from piercing the carcass substrate. With the above structure, it is convenient to improve the puncture-proof effect of the SBS waterproof coiled material, and further avoid the phenomenon that the SBS waterproof coiled material is pierced by force collision or sharp objects.

[0033] The outer surface shape and size of the protrusion 3 are both adapted to the inner cavity shape and size of the groove 4, so as to place the protrusion 3 on the adjacent SBS waterproof coiled material 1 into the groove 4 on the adjacent SBS waterproof coiled material 1, thereby facilitating the tight connection at the gap between adjacent SBS waterproof coiled materials 1.

[0034] The SBS waterproof coiled material 1 includes a carcass matrix 11. Anti-puncture structures 12 are provided on both the upper and lower sides of the carcass matrix 11. Modified asphalt adhesive layers 13 are provided on both the upper and lower sides of the anti-puncture structures 12.

The side of the second anti-puncture layer 122 away from the first anti-puncture layer 121 is connected to the modified asphalt adhesive layer 13. By peeling off the release layer 14 on the SBS waterproof coiled material 1 and bonding the modified asphalt adhesive layer 13 to the building object, at this time, the first anti-puncture layer 121 and the second anti-puncture layer 122 sequentially provided on both the upper and lower sides of the carcass matrix 11 can prevent sharp objects from piercing the carcass matrix 11. With the above structure, it is convenient to improve the anti-puncture effect of the SBS waterproof coiled material 1, and further avoid the phenomenon that the SBS waterproof coiled material 1 is pierced by force collision or sharp objects.

[0036] The thickness of the second puncture-proof layer 122 is twice that of the first puncture-proof layer 121.

[0037] The first puncture-proof layer 121 is made of polyester, which is a lightweight material with puncture-proof, scratch-resistant and tear-resistant properties.

[0038] The thickness of the modified asphalt adhesive layer 13 is equal to that of the first puncture-proof layer 121.

[0039] The thickness of the tire matrix 11 is greater than that of the second puncture-proof layer 122.

[0040] Working principle: By peeling off the release layer 14 on the SBS waterproof coil 1 and bonding the modified asphalt adhesive layer 13 to the building object, at this time, the first puncture-proof layer 121 and the second puncture-proof layer 122 arranged on the upper and lower sides of the tire matrix 11 can prevent sharp objects from piercing the tire matrix 11. With the above structure, it is convenient to improve the puncture-proof effect of the SBS waterproof coil 1, and thus avoid the phenomenon that the SBS waterproof coil 1 is pierced by force collision or sharp objects;

[0041] Then, by placing the protrusions 3 on the adjacent SBS waterproof coils 1 into the grooves 4 on the adjacent SBS waterproof coils 1 and then performing melting bonding, the tight connection at the gaps between the adjacent SBS waterproof coils 1 can be completed, so as to ensure the tight connection at the gaps between the adjacent waterproof coils, and thus prevent water seepage and leakage. This device can not only ensure the tight connection at the gaps between the adjacent waterproof coils, but also prevent water seepage and leakage.
