[0004] The technical solution of the test sample for the high-temperature water tolerance of the waterproof materials of the present invention is realized as follows: A test sample for the high-temperature water tolerance of waterproof materials with more accurate testing, characterized in that: it includes two layers of waterproof materials, which are an upper waterproof material and a lower waterproof material respectively. The upper waterproof material and the lower waterproof material are adhesively connected, and the adhesive part is a closed structure, which is the first adhesive part. A cavity is formed between the upper waterproof material, the lower waterproof material, and inside the first adhesive part, and this cavity is the first cavity. Two conductive meshes are placed in the first cavity, which are the upper conductive mesh above and the lower conductive mesh below. The upper conductive mesh is above the first cavity, and the lower conductive mesh is below the first cavity. There is dry water storage resin between the two conductive meshes, and two power lines are respectively connected to the upper conductive mesh and the lower conductive mesh and led out to the outside, and these two power lines are the first power lines.

[0005] Furthermore, there is a closed second bonding part on the outer periphery of the first bonding part. There is a distance between the first bonding part and the second bonding part. A cavity is formed between the upper waterproof material, the lower waterproof material, outside the first bonding part, and inside the second bonding part. This cavity is the second cavity. Two annular conductive meshes are placed in the second cavity, namely the upper annular conductive mesh above and the lower annular conductive mesh below. An annular water storage resin is in contact between the two annular conductive meshes. This annular resin is the second resin. There are also two power lines respectively connected to the upper annular conductive mesh and the lower annular conductive mesh and led out to the outside. These two power lines are the second power lines respectively.

[0006] Furthermore, the first bonding part and the second bonding part are respectively an annular structure or a square structure.

[0007] The technical solution of the production device for the waterproof material high-temperature water tolerance test sample of the present invention is realized as follows: The production device for the waterproof material high-temperature water tolerance test sample is characterized in that: it includes a device frame. There is a conveyor belt driven by a motor on the device frame. The device frame has an inlet end at the back and a product outlet end at the front. A rear placement station, a coating station, a gluing station, a front placement station, and a pressing station are sequentially arranged on the device frame from back to front. The conveyor belt passes through the rear placement station, the coating station, the gluing station, the front placement station, and the pressing station in sequence.

[0008] The rear placement station is a station for placing the lower waterproof material. The coating station is a station for placing the water storage resin layer in the middle of the lower waterproof material. The gluing station is a station for applying an adhesive around the water storage resin layer of the lower waterproof material. The front placement station is a station for placing the upper waterproof material. The pressing station is a station for pressing the lower waterproof material and the upper waterproof material together with an adhesive.

[0009] There is a coating outlet above the coating station, and the coating outlet faces the coating station. During production, the coating outlet can apply the water storage resin, which is the central water storage resin, on the lower waterproof material. There is a gluing device on the gluing station. The gluing device has a gluing outlet. The gluing device is connected to a control device. The gluing device includes a positioning probe. A turntable is installed around the positioning probe. The gluing outlet is installed on the turntable. When the positioning probe detects that there is a water storage resin layer below, the control device makes the turntable rotate, and the gluing outlet applies an annular adhesive, which is the inner annular adhesive, that is, the first adhesive, around the water storage resin layer.

[0010] The pressing station is equipped with a stamping head connected to a telescopic component. The stamping head is provided with a detection device, which is connected to a control device. The detection device has downward protruding ribs, and the protruding ribs are in the shape of the bonding glue. When the upper waterproof material moves under the stamping head, the detection device detects the information and transmits this information to the control device. The control device activates the stamping head, and the stamping head moves downward and acts on the upper waterproof material, bonding the upper waterproof material and the lower waterproof material together through the bonding glue.

The front coating station can form an annular water storage resin ring around the first bonding glue; there is also another glue coating station in front of the glue coating station, which is the front glue coating station. The front glue coating station can apply a ring of bonding glue around the water storage resin ring, and this bonding glue ring is the first bonding glue.

[0012] Furthermore, the coating outlet can also form an annular resin band around the central water storage resin. This annular resin band is the second resin band, and there is a distance between the central water storage resin and the second resin band.

Detailed implementation mode

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] As Figure 1 shown, the test sample of the high-temperature water tolerance of the waterproof material is characterized in that: it includes two layers of waterproof materials, which are the upper waterproof material A1 and the lower waterproof material A2 respectively. The upper waterproof material and the lower waterproof material are adhesively connected, and the bonding part is a closed structure, which is the first bonding part A3. A cavity is formed between the upper waterproof material, the lower waterproof material and inside the first bonding part, and this cavity is the first cavity A4. Two conductive nets are placed in the first cavity, which are the upper conductive net A5 above and the lower conductive net A6 below respectively. The upper conductive net is above the first cavity, and the lower conductive net is below the first cavity. There is dry water storage resin A7 between the two conductive nets, and two power lines are respectively connected to the upper conductive net and the lower conductive net and led out to the outside, and these two power lines are the first power line A8.

[0023] When the present invention is in use, connect the first power cord to an external circuit, place the present tolerance test sample in water, heat the water, and when the temperature rises to a certain level, after a period of time (usually 60 - 100 minutes), check whether the external circuit is turned on. If it is turned on or turned on midway, it indicates that the waterproof material does not have tolerance at this temperature. If it is not turned on, it indicates that the waterproof material has tolerance at this temperature. The working principle is that if it is not turned on, the waterproof material is not damaged, water will not enter the first cavity, and the water storage resin remains dry. If it is turned on, the waterproof material is damaged, water will enter the first cavity, the water storage resin stores water, and the circuit will be turned on.

[0024] Furthermore, there is a closed second bonding part A9 on the outer periphery of the first bonding part. There is a distance between the first bonding part and the second bonding part. A cavity is formed between the upper waterproof material, the lower waterproof material, outside the first bonding part, and inside the second bonding part. This cavity is the second cavity A10. Two annular conductive meshes are placed in the second cavity, namely the upper annular conductive mesh A11 above and the lower annular conductive mesh A12 below. An annular water storage resin is in contact between the two annular conductive meshes. This annular resin is the second resin A13. There are also two power cords respectively connected to the upper annular conductive mesh and the lower annular conductive mesh and led out to the outside. These two power cords are the second power cords A14 respectively.

[0025] When the present invention is in use, on the basis of the above, connect the second power cord to another circuit. This circuit is the second circuit;

[0026] If the second circuit is turned on while the first circuit is not turned on, it may be that the second bonding part is cracked and the test fails;

[0027] If the second circuit is turned on and the first circuit is turned on, it may be that the first bonding part and the second bonding part are cracked and the test fails;

[0028] If the second circuit is not turned on, it indicates that the second bonding part is firmly bonded, water will not enter the second cavity and even the first cavity through the second bonding part, and the test result is reliable and can be used as the test result.

[0029] In one embodiment, the first bonding part and the second bonding part are respectively an annular structure or a square structure.

[0030] In another embodiment, the area of the first cavity is larger than the area of the second cavity.

[0031] In one embodiment, the area of the first cavity is 3 - 5 times the area of the second cavity.

[0032] With such a setting of the present invention, the inaccurate rate of testing can be reduced.

[0033] As Figure 2 shown, a production device for testing the tolerance of waterproof materials in high-temperature water is characterized in that: it includes a device frame 1B, on which there is a conveyor belt 2B driven by a motor. The device frame has an inlet end at the back and a product outlet end at the front. From the back to the front on the device frame, there are successively arranged a rear placement station 3B, a coating station 4B, a gluing station 5B, a front placement station 6B, and a pressing station 7B. The conveyor belt passes through the rear placement station, the coating station, the gluing station, the front placement station, and the pressing station in sequence;

[0034] The rear placement station is a station for placing the lower-layer waterproof material. For example, the lower-layer waterproof material is manually placed on this station. The lower-layer waterproof material includes a layer of waterproof material to be tested below and a lower conductive net above the waterproof material. The lower conductive net also has a wire connected to it, and this wire is the wire serving as the first power supply line;

[0035] Of course, a placement robot can also be installed at the rear placement station to place the lower-layer waterproof material by the robot.

[0036] The coating station is a station for placing the water storage resin layer in the middle of the lower-layer waterproof material (above the lower conductive net). There is a coating outlet 41B above the coating station, and the coating outlet faces the coating station. During production, the coating outlet can coat the water storage resin on the lower waterproof material, and this water storage resin is the central water storage resin;

[0037] For example, a glue coating valve 42B is installed at the coating outlet, and the coating valve is connected to a probe 43B. When the probe detects that there is a lower-layer waterproof material coming, the probe opens the valve, and the coating outlet releases the water storage resin;

[0038] The gluing station is a station for coating an adhesive around the water storage resin layer of the lower-layer waterproof material. There is a gluing device 51B on the gluing station. The gluing device has a gluing outlet 52B. The gluing device is connected to a control device. The gluing device includes a positioning probe 53B, and a turntable 54B is installed around the positioning probe. The gluing outlet is installed on the turntable. When the positioning probe detects that there is a water storage resin layer below, the control device rotates the turntable, and the gluing outlet coats a ring-shaped adhesive around the water storage resin layer. This adhesive is an inner ring-shaped adhesive, that is, the first adhesive;

[0039] The front placement station mentioned above is a station for placing the upper waterproof material. For example, the upper waterproof material is placed on this station manually. The upper waterproof material includes a layer of waterproof material to be tested on the top and an upper conductive net below the waterproof material. The upper conductive net also has a wire connected to it, and this wire is the wire of the first power supply line.

[0040] The pressing station is a station for pressing the lower waterproof material and the upper waterproof material together with an adhesive. Of course, a placement robot can also be installed at the front placement station to place the upper waterproof material by the robot. Above the pressing station, there is a punching head 71B connected by a telescopic component. The punching head has a detection device 72B. The detection device is connected to a control device. The detection device has a downward convex rib 73B. The convex rib is a convex rib that matches the shape of the first adhesive. When the upper waterproof material moves below the punching head, the detection device detects information and transmits this information to the control device. The control device activates the punching head, and the punching head moves downward. The punching head acts on the upper waterproof material, bonding the upper waterproof material and the lower waterproof material together through the adhesive.

[0041] Furthermore, the convex rib includes an inner convex rib and an outer convex rib. The inner convex rib has the structure of the first bonding part, and the inner convex rib is the convex rib that presses the first bonding part. The outer convex rib has the structure of the second bonding part, and the outer convex rib is the convex rib that presses the second bonding part.

[0042] Furthermore, there is another coating station in front of the coating station. This coating station is the front coating station. The front coating station can form an annular water storage resin ring around the first adhesive. In front of the glue application station, there is another glue application station. This glue application station is the front glue application station. The front glue application station can apply a ring of adhesive around the water storage resin ring, and this ring of adhesive is the second adhesive.

[0043] The present invention is arranged in this way because some waterproof material high-temperature water tolerance test samples also have an outer annular water storage resin. Setting this front coating station can apply the outer annular water storage resin.

[0044] Similarly, some waterproof material high-temperature water tolerance test samples also have an outer annular water storage resin. Setting this front glue application station can seal the outer annular water storage resin.

[0045] Furthermore, the coating outlet can also form an annular resin belt around the central water storage resin, that is, the side of the coating outlet is also connected to an outer material outlet outside. This annular resin belt is the second resin belt, and there is a distance between the central water storage resin and the second resin belt.

[0046] With this configuration of the present invention, it is possible to apply a central water storage resin on the lower waterproof material layer and also apply an annular resin band in one go, saving the coating process.

[0047] Furthermore, the glue application outlet further includes an outer glue application outlet 55B. The outer glue application outlet applies an adhesive on the second resin band, and this adhesive is the peripheral adhesive.

[0048] With this configuration of the present invention, it is possible to apply a sealing central water storage resin adhesive on the lower waterproof material layer and also apply a sealing annular resin band adhesive in one go, simultaneously forming a first adhesive and a second adhesive, saving the glue application process and the coating process.

[0049] The technical solution of the method for testing the tolerance of the waterproof material of the present invention in high-temperature water is realized as follows: For the method for testing the tolerance of the waterproof material in high-temperature water, use the above test sample, place it in water, connect the first power cord to the external circuit, heat the water, and observe whether the circuit is turned on after a period of time under a high temperature. If it is not turned on, it indicates that the waterproof material has tolerance at this temperature. If it is turned on, it indicates that the waterproof material does not have tolerance at this temperature.

[0050] Furthermore, the second power cord is also connected to a circuit, and this circuit is the second circuit. If the second circuit is turned on after a period of time, it indicates that the test fails or is in doubt (not regarded as the test result). If the second circuit is not turned on after a period of time, it indicates that the test is successful and the record is valid.

[0051] At this time, if the second circuit is turned on, it may be because the outermost bonding part is not firmly bonded, and water enters from this bonding part, affecting the test result. Therefore, it cannot be regarded as the test result.

[0052] At this time, if the second circuit is not turned on, the outermost bonding part is firmly bonded, and water will not enter from this bonding part, and the test result is reliable and valid.

[0053] So far, the technical solution of the present invention has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
