[0002] As a widely used waterproof material, waterproof membrane covers a variety of roof systems, such as flat roof systems, pitched roof systems, metal roof systems, etc. In these roof systems, waterproof membrane is a key component of the waterproof layer. Although it generally has good weather resistance to ensure that the roof is not corroded, it is subject to the roof structure and the influence of some environmental factors. Most of the waterproof membranes on the market will still be damaged. In this case, it is difficult to accurately detect the leakage point (i.e. the damage position) by conventional means. Once the leakage point is not found in time for repair, the roof erosion will be further aggravated. Summary of the invention

[0003] In response to at least one of the above-mentioned defects or shortcomings of the prior art, the present application provides a waterproof membrane that can form conductive points at leakage points, which is conducive to accurate detection of leakage points and effectively reduces the difficulty of detection.

[0004] In order to achieve the above-mentioned purpose, the present application provides a waterproof roll material, which is provided with a roll material insulation surface layer and a roll material conductive layer which are stacked and fixed up and down, and the surface of the roll material insulation surface layer serves as the surface of the waterproof roll material; when there is a leakage point on the roll material insulation surface layer, the local position of the roll material conductive layer can be exposed through the leakage point so that it can be detected by the high-voltage probe of the electric spark leak detector.

[0005] In some embodiments, the waterproof roll material is further provided with a roll material insulating bottom layer, and the roll material insulating surface layer, the roll material conductive layer and the roll material insulating bottom layer are stacked in sequence from top to bottom.

[0006] In some embodiments, the coiled material insulation surface layer and the coiled material insulation bottom layer are both polymer weather-resistant layers, and the coiled material conductive layer is a fiber-reinforced layer.

[0007] In some embodiments, the waterproof membrane is further provided with a membrane adhesive layer as the bottom layer.

[0008] In some embodiments, the insulating surface layer of the coiled material is a polymer weather-resistant layer, the conductive layer of the coiled material is a fiber-reinforced layer, and the adhesive layer of the coiled material is a fiber adhesive layer.

[0009] In some embodiments, the waterproof roll material is further provided with a roll material insulating inner layer, and the roll material insulating surface layer, the roll material conductive layer, the roll material insulating inner layer and the roll material adhesive layer are stacked in sequence from top to bottom.

[0010] In some embodiments, the coil insulation surface layer and the coil insulation inner layer are both polymer weather-resistant layers, the coil conductive layer is a fiber reinforcement layer, and the coil bonding layer is a fiber bonding layer.

[0011] In some embodiments, the coiled conductive layer is a conductive adhesive composite layer.

[0012] In some embodiments, the insulating surface layer of the coiled material is a polymer weather-resistant layer, and the conductive adhesive composite layer is a mixed fiber adhesive layer.

[0013] In some embodiments, the conductive layer of the roll material is a negative thermal expansion layer, and the remaining structural layers in the waterproof roll material are thermal expansion layers.

[0014] Through the above technical solution, once the waterproof coiled material of the present application has a leakage point, it means that the insulating surface layer of the coiled material is damaged, and the conductive layer of the coiled material exposes the insulating surface layer of the coiled material through the damaged position, so that the leakage point is formed into a conductive point. Therefore, when the waterproof coiled material is required to be detected for leakage points, the high-voltage probe of the electric spark leak detector can be used to comprehensively scan the waterproof coiled material laid on the roof. When an electric spark is observed between the high-voltage probe and the scanned position on the surface of the waterproof coiled material, it means that the exposed conductive layer of the coiled material is connected with the high-voltage probe, so that the position of the leakage point can be accurately determined, so as to repair the leakage point in time and solve the problem of roof erosion. The detection process is clear, intuitive and has low operation difficulty, which helps to save construction costs.

[0033] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0034] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with exemplary embodiments.

[0035] In the prior art, a variety of methods can be used to detect leakage points of roof waterproofing membranes, such as visual inspection method, water pressure test method, infrared thermal imaging method, ultrasonic detection method, pulse method, etc. Among them, the visual inspection method can find obvious signs of leakage, such as wet marks, water stains, mildew, etc. through the naked eye or visual inspection of the surface conditions of the material. The method is simple and intuitive, but it is only suitable for preliminary inspection; the water pressure test method applies a certain water pressure to the roof and observes the changes in water pressure to find the leakage point, but this method is relatively expensive; the infrared thermal imaging method can use infrared rays to detect changes in roof surface temperature. The leakage site has a temperature difference with other sites due to water content, so it is displayed as a different color area in the infrared thermal image, but when the outdoor sunlight radiation is large, it is difficult to accurately detect the leakage point; the ultrasonic detection method uses ultrasonic waves to detect cracks in the concrete and indirectly judge the leakage site, but it is only suitable for some concrete roofs with larger cracks; the pulse method detects the leakage location by laying cables above and below the waterproof layer and using the principle of pulse changes generated by electric current passing through the seepage point, but this method requires burying cables during waterproof construction, which is difficult and costly.

[0036] Although the above methods combine different principles and technical means to effectively locate the leakage points of roof waterproofing membranes, in actual operation, they are more or less restricted by factors such as the specific conditions of the roof, detection conditions and cost budget, making it difficult to achieve ideal detection results.

[0037] In view of this, if Figures 1 to 7 As shown, the first exemplary embodiment of the present application provides a method for detecting leakage points of a waterproof coiled material, the method comprising the steps of:

[0038] S1: Scan the surface of the waterproofing coiled material 1 using the high voltage probe 201 of the spark detector 2, wherein the waterproofing coiled material 1 is provided with a coiled material insulating surface layer 101 and a coiled material conductive layer 102 which are stacked and fixed up and down, and the surface of the coiled material insulating surface layer 101 serves as the surface of the waterproofing coiled material 1;

[0039] S2: When electric sparks are observed between the high-voltage probe 201 and the scanned position on the surface of the waterproof membrane 1, it is determined that there is a leakage point at the scanned position; when electric sparks are observed not to be generated between the high-voltage probe 201 and the scanned position, it is determined that there is no leakage point at the scanned position.

[0040] Therefore, when the operator uses the high-voltage probe 201 of the spark detector 2 to scan the waterproof roll 1 laid on the roof, the damaged waterproof roll 1 will cause the roll conductive layer 102 to be exposed, forming the above-mentioned leakage point. Therefore, when it is observed that the high-voltage probe 201 and the scanned position on the surface of the waterproof roll 1 generate sparks, it means that the exposed roll conductive layer 102 and the high-voltage probe 201 form a flash connection. According to the position of the spark, it can be determined that the waterproof roll 1 has a leakage point at this location. If the scanned position does not generate sparks, it can be determined that the waterproof roll at this location is intact. It can be seen that the detection method of this exemplary embodiment is simple and fast, and it is easy to deal with large-area roof leakage point detection, and the detection results are clear and intuitive, which effectively improves the accuracy of detection and reduces detection costs.

[0041] In addition, the location that has been determined to be a leak point can be marked to facilitate subsequent repair of the leak point, thereby effectively and promptly solving the problem of roof erosion.

[0042] In one embodiment, the spark detector 2 may include a voltmeter (not shown in the drawings) for displaying the real-time voltage of the high-voltage probe 201. Since the voltmeter is very sensitive to the voltage change of the high-voltage probe 201, once the high-voltage probe 201 is connected to other conductors, a pulse discharge is generated between the electrodes, and the voltage of the high-voltage probe 201 will decrease instantly.

[0043] To this end, the waterproof coiled material leakage detection method of this exemplary embodiment also includes:

[0044] When the voltage indication on the spark detector 2 decreases, it is determined that there is a leakage point at the scanned position; when the voltage indication on the spark detector 2 remains unchanged, it is determined that there is no leakage point at the scanned position.

[0045] Therefore, when the operator uses the spark leak detector 2 to scan the waterproof membrane 1 laid on the roof, he can not only determine whether a leakage point occurs at the scanned position by observing whether the high-voltage probe 201 generates sparks, but also determine whether a leakage point is detected by observing the change in the voltage reading of the voltmeter, thereby improving the detection accuracy.

[0046] Furthermore, in one embodiment, the spark detector 2 also includes an alarm (not shown in the drawings) for issuing an alarm signal, and the alarm can determine the timing of issuing the alarm signal based on the voltage change of the high-voltage probe 201. Specifically, when the real-time voltage of the high-voltage probe 201 is lower than a preset voltage threshold, the alarm sends an alarm signal.

[0047] To this end, the waterproof membrane leakage detection method also includes:

[0048] When the alarm on the spark leak detector 2 sends out an alarm signal, it is determined that there is a leakage point at the scanned position; when the alarm on the spark leak detector 2 does not send out an alarm signal, it is determined that there is no leakage point at the scanned position.

[0049] Therefore, when the operator uses the spark leak detector 2 to scan the waterproof membrane 1 laid on the roof, he can not only determine whether there is a leakage point at the scanned position by observing whether the high-voltage probe 201 generates sparks and whether the voltage reading of the voltmeter changes, but also determine whether the leakage point is detected by observing whether the alarm sends an alarm signal, thereby further improving the detection accuracy and avoiding leakage points from being missed.

[0050] In this embodiment, the alarm may be a sound alarm, a light alarm, a vibration alarm, etc., as long as it is a device that can emit a signal that can be perceived by people, and this application does not limit this.

[0051] like Figures 1 to 7 As shown, the second exemplary embodiment of the present application provides a waterproof membrane leakage point detection system, which includes a waterproof membrane 1 and an electric spark leak detector 2, wherein the waterproof membrane 1 is provided with an insulating surface layer 101 and a conductive layer 102 stacked and fixed up and down, and the surface of the insulating surface layer 101 serves as the surface of the waterproof membrane 1; the electric spark leak detector 2 is provided with a high-voltage probe 201 for scanning the leakage point on the surface of the waterproof membrane 1, and when the high-voltage probe 201 scans the leakage point, an electric spark can be generated between the high-voltage probe 201 and the conductive layer 102 of the membrane partially exposed at the leakage point.

[0052] Specifically, in addition to the high-voltage probe 201, the spark detector 2 also includes a high-voltage generator (not shown in the drawings) as a core component, which is electrically connected to the high-voltage probe 201 and is responsible for generating high-voltage pulses, so that the high-voltage probe 201 applies the high-voltage pulses to the surface of the object to be detected. If there is a conductive structure on the surface of the object to be detected, when the high-voltage probe 201 is close to the conductive structure, the voltage pulse can be derived from the conductive structure, forming an air gap breakdown between the conductive structures and generating sparks.

[0053] Therefore, when detecting leakage points on a roof covered with a waterproof membrane 1, the spark leak detector 2 can be used to scan the surface of the waterproof membrane 1. Once a spark is generated between the high-voltage probe 201 and the surface of the waterproof membrane 1, it can be determined that there is a leakage point at that location. The process is simple and fast, easy to operate, and the high-voltage probe 201 is very sensitive, so that the positioning accuracy is high.

[0054] In one embodiment, the spark detector 2 is further provided with a display or the above-mentioned voltmeter (not shown in the drawings) capable of displaying the voltage value of the high-voltage probe 201. During the scanning process, when the voltage value displayed on the display decreases, it means that there is a leakage point at the scanned position. If the display reading remains unchanged or fluctuates slightly, it can be determined that there is no leakage point at the scanned position.

[0055] Furthermore, the spark detector 2 is also provided with an alarm (not shown in the drawings) that can send out an alarm signal when sparks are generated between the high-voltage probe 201 and the coil conductive layer 102 partially exposed at the leakage point. For example, the alarm can receive a pulse signal from the above-mentioned high-voltage generator, and when the pulse signal fluctuates greatly, the alarm can send out an audible and visual alarm signal to indicate the leakage point detected by the operator.

[0056] In one embodiment, referring to Figure 7 The high-voltage probe 201 is a high-voltage electrode mesh plate 2011 that can move in contact with the surface of the waterproof coiled material 1. The high-voltage electrode mesh plate 2011 has a large area and a wide scanning range, which can effectively improve the detection efficiency. During the scanning process, by moving the high-voltage electrode mesh plate 2011 in contact with the surface of the waterproof coiled material 1, the detection success rate can be effectively guaranteed, and by observing the grid position of the electric spark generated by the high-voltage electrode mesh plate 2011, the leakage point of the waterproof coiled material can be accurately located.

[0057] Further, refer to Figure 7 The spark detector 2 is also provided with an oblique long connecting rod 202, the bottom of which is connected to the high-voltage electrode mesh plate 2011 and the top of which is connected to the handheld insulating structure 203. Thus, the operator can push the high-voltage electrode mesh plate 2011 to move by holding the insulating structure 203 while walking, without bending over to operate, and the oblique long connecting rod 202 will not block the operator from observing the high-voltage electrode mesh plate 2011, so that the operator has a better experience.

[0058] At present, the waterproofing membrane used in metal roofing systems is mainly bonded, and metal roofing systems generally use corrugated metal plates as roof structures, which have a large number of peaks and troughs. In actual construction, construction workers are required to bond the waterproofing membrane to the metal plate in the form of a film. The membrane itself is composed of heat-expanding materials. When exposed to the environment for a long time, it will deform, causing the originally compliant membrane to peel off the metal plate, which in turn causes the metal plate to be eroded by rainwater, affecting the roof structure.

[0059] To this end, in one embodiment of the present application, the coiled conductive layer 102 can be made of a negative thermal expansion material, such as a carbon fiber material, and the remaining structural layers in the waterproof coiled material 1 are all made of thermal expansion materials, such as polyester fibers, etc. Among them, the coiled conductive layer 102 made of a negative thermal expansion material will not produce permanent deformation due to the influence of the climate environment, and at the same time, by utilizing its negative thermal expansion performance, it can reversely offset the deformation of each structural layer made of thermal expansion material, thereby reducing or even eliminating the deformation of the waterproof coiled material 1 caused by climate change, avoiding the situation of peeling off the roof structure layer, and realizing effective and long-term protection of the roof structure layer.

[0060] In the case where the coil conductive layer 102 is provided, in order to save the setting of the adhesive layer, refer to Figure 3 The coiled conductive layer 102 may be a conductive adhesive composite layer 106. The conductive adhesive composite layer 106 has both conductivity and adhesiveness, and can effectively save costs. The conductive adhesive composite layer 106 may be made of a composite of viscose fiber and carbon fiber, or a composite of viscose fiber and metal fiber, and this application does not limit this.

[0061] Of course, in the case of an additional adhesive layer, the waterproof roll 1 can also be provided with a roll adhesive layer 104 as the bottom layer, for example, Figure 2 The insulating surface layer 101, the conductive layer 102 and the adhesive layer 104 are stacked in sequence from top to bottom to form a waterproof roll 1 with a three-layer structure. Figure 4 As shown, two insulating layers are provided, the coiled conductive layer 102 is provided between the two insulating layers, and the coiled adhesive layer 104 is provided at the bottom layer, forming a waterproof coiled material 1 with a four-layer structure to improve the waterproof effect. In practical applications, the arrangement positions between different material layers can be determined according to the adhesion and waterproof performance between different material layers, and this application does not limit this.

[0062] The present application also provides a waterproof roll material accordingly. In a specific embodiment, see Figures 1 to 6 The waterproof roll material 1 is provided with a roll material insulating surface layer 101 and a roll material conductive layer 102 which are fixedly stacked up and down, and the surface of the roll material insulating surface layer 101 serves as the surface of the waterproof roll material 1; when there is a leakage point in the roll material insulating surface layer 101, a local position of the roll material conductive layer 102 can be exposed through the leakage point so as to be detected by the high-voltage probe 201 of the electric spark leak detector 2.

[0063] Therefore, once a leakage point appears in the waterproofing coiled material 1 of this exemplary embodiment, it means that the insulating surface layer 101 of the coiled material is damaged, and the conductive layer 102 of the coiled material exposes the insulating surface layer 101 of the coiled material through the damaged position, so that the leakage point is formed into a conductive point. When it is required to detect the leakage point of the waterproofing coiled material 1, the high-voltage probe 201 of the electric spark leak detector 2 can be used to comprehensively scan the waterproofing coiled material 1 laid on the roof. When it is observed that an electric spark is generated between the high-voltage probe 201 and the scanned position on the surface of the waterproofing coiled material 1, it means that the exposed conductive layer 101 of the coiled material is connected with the high-voltage probe 201. Thus, the position of the leakage point can be accurately determined, so as to repair the leakage point in time and solve the problem of roof erosion. The detection process is clear, intuitive and has low operation difficulty, which helps to save construction costs.

[0064] In one embodiment, referring to Figure 1 The waterproofing coiled material 1 is also provided with a coiled material insulating bottom layer 103, and the coiled material insulating surface layer 101, the coiled material conductive layer 102 and the coiled material insulating bottom layer 103 are stacked in sequence from top to bottom.

[0065] The coiled material insulation surface layer 101 and the coiled material insulation bottom layer 103 can both be polymer weather-resistant layers, and the coiled material conductive layer 102 is a fiber reinforcement layer. By providing two layers of polymer weather-resistant layers, the overall waterproof effect of the waterproof coiled material 1 can be effectively improved. Once the polymer weather-resistant layer on the surface is damaged, the polymer weather-resistant layer on the bottom layer can also resist the leaking rainwater to prevent the roof from being damaged.

[0066] In one embodiment, referring to Figure 2 and Figure 4 The waterproofing membrane 1 is also provided with a membrane adhesive layer 104 as the bottom layer. The membrane adhesive layer 104 has a better bonding effect. By setting the membrane adhesive layer 104 at the bottom layer, the construction workers can stick the waterproofing membrane 1 on the roof structure in the form of a film, simplifying the construction process and improving the construction efficiency.

[0067] Specifically, Figure 2 As shown, the waterproof roll 1 can be composed of a roll insulation surface layer 101, a roll conductive layer 102 and a roll adhesive layer 104 stacked in sequence from top to bottom, wherein the roll insulation surface layer 101 is a polymer weather-resistant layer, the roll conductive layer 102 is a fiber reinforcement layer, and the roll adhesive layer 104 is a fiber adhesive layer.

[0068] Further, in order to improve the overall waterproof effect of the waterproof membrane 1, refer to Figure 4 The waterproofing roll 1 is also provided with a roll insulation inner layer 105. Specifically, the roll insulation surface layer 101, the roll conductive layer 102, the roll insulation inner layer 105 and the roll adhesive layer 104 are stacked in sequence from top to bottom.

[0069] The coiled material insulation surface layer 101 and the coiled material insulation inner layer 105 can both be polymer weather-resistant layers, the coiled material conductive layer 102 is a fiber reinforcement layer, and the coiled material bonding layer 104 is a fiber bonding layer. The waterproof coiled material 1 composed of two layers of polymer weather-resistant layers has a better waterproof effect, and the fiber bonding layer has a better bonding effect with the polymer weather-resistant layer as the inner layer, so that the overall deformation resistance of the waterproof coiled material 1 is better.

[0070] In one embodiment, referring to Figure 3 The conductive layer 102 of the roll material is a conductive adhesive composite layer 106. The conductive adhesive composite layer 106 has both conductivity and adhesiveness, so that the waterproof roll material 1 composed of the roll material insulating surface layer 101 and the conductive adhesive composite layer 106 can be directly pasted on the roof structure without the need to additionally set up the roll material adhesive layer 104 as the bottom layer, effectively saving material costs.

[0071] Specifically, the coil insulation surface layer 101 is a polymer weather-resistant layer, and the conductive adhesive composite layer 106 is a mixed fiber adhesive layer.

[0072] It should be noted that the polymer weather-resistant layer described in the above embodiments can be made of insulating materials such as TPO, PVC, EPDM, etc., the fiber reinforcement layer can be woven from carbon fiber bundles 1021 or blended fiber bundles 1061, the fiber bonding layer can be made of inorganic fibers such as polyester fibers and nylon, and the blended fiber bonding layer can be woven from blended fiber bundles 1061.

[0073] Specific as Figure 5 and Figure 6 As shown, the carbon fiber bundle 1021 is composed of a plurality of carbon fiber filaments 10211, and the mixed fiber bundle 1061 is composed of a plurality of carbon fiber filaments 10211 and a plurality of polymer fiber filaments (such as polyester fiber filaments, nylon fiber filaments, etc.), wherein the plurality of polymer fiber filaments can be wrapped around the plurality of polymer fiber filaments.

[0074] It can be understood that since the fiber reinforcement layer is woven from carbon fiber bundles 1021 or blended fiber bundles 1061, once the waterproof membrane 1 is damaged, a leakage point will appear, and the carbon fiber bundles 1021 or blended fiber bundles 1061 will form exposed ends at the leakage points, similar to the thread ends of clothes. In this way, when the surface of the waterproof membrane 1 is scanned using the electric spark leak detector 2, once the high-voltage probe 201 is close to or touches the exposed end of the fiber reinforcement layer, an electric spark will be instantly generated, thereby locating the leakage point.

[0075] like Figure 1 and Figure 4In the embodiment shown, in actual production, the area of ​​the fiber-reinforced layer needs to be set smaller than that of other structural layers to avoid exposure of the fiber-reinforced layer; if the fiber-reinforced layer needs to be exposed after cutting the waterproof membrane 1, a homogeneous waterproof membrane needs to be used to wrap and cover the exposed fiber-reinforced layer.

[0076] In one embodiment, the conductive layer 102 of the roll is a negative thermal expansion layer, such as the fiber reinforcement layer made of woven carbon fiber bundles, and the remaining structural layers in the waterproof roll 1 are thermal expansion layers, such as the polymer weather-resistant layer. Among them, carbon fiber is an inorganic material, which will not be permanently deformed due to the influence of climate. At the same time, the carbon fiber material has the property of negative thermal expansion, so that it can reversely resist the deformation of the remaining structural layers caused by thermal expansion, thereby stabilizing the overall structure of the waterproof roll 1, especially as Figures 2 to 4 The waterproof membrane 1 shown can effectively solve the problem of roof peeling due to climate change.

[0077] In addition, the tensile strength of carbon fiber ranges from approximately 1300Mpa to 4000Mpa, while the tensile strength of traditional polyester fiber is approximately 230Mpa. Using a fiber reinforcement layer woven from carbon fiber bundles as the inner layer of the waterproof membrane 1 greatly improves its overall tensile and tear resistance, effectively resisting damage to the waterproof membrane 1 caused by extreme weather or other external factors, and extending the service life of the waterproof membrane 1.
