Description

Technical Field

[0001] The utility model relates to the field of waterproof coatings, in particular to a tool for testing the low-temperature flexibility of waterproof coatings. Background Art

[0002] (1) Low temperature flexibility index is one of the important indicators for evaluating the performance of waterproof coatings. It is of great significance for ensuring the waterproof effect of coatings, enhancing the weather resistance and service life of coatings, and adapting to different engineering needs.

[0003] 1. Ensure the waterproof effect of the coating: The low-temperature flexibility index can reflect the performance of the waterproof coating in a low-temperature environment. If the low-temperature flexibility index of the coating is unqualified, problems such as cracking and crazing may occur in a low-temperature environment, thus affecting the waterproof effect of the coating.

[0004] 2. Enhance the weather resistance and service life of the coating: Waterproof coatings with good low-temperature flexibility indicators can adapt to various harsh environmental conditions, such as low temperature, high temperature, drought, humidity, etc., thereby enhancing the weather resistance and service life of the coating.

[0005] 3. Adapt to different engineering needs: Different engineering environments have different requirements for waterproof coatings. The low-temperature flexibility index can meet the needs of different projects, such as winter construction in the north and summer construction in the south.

[0006] In summary, low-temperature flexibility is often used as a coating ex-factory indicator and is an extremely important indicator that is frequently tested by the market and production plants.

[0007] (II) There are currently two mainstream testing methods on the market, one is machine automatic testing, and the other is manual bending testing. Machine testing is more convenient and quick, but the machine is expensive, and some parts are prone to corrosion and rust when placed in a low-temperature cold air environment for a long time, causing damage to the device. In manual bending testing, there are many human factors, so the test results of different people have large deviations. Moreover, when the same person tests, since it is necessary to bend one by one, the manual test takes a long time, which will affect the temperature of the test piece. Therefore, the later the test piece is bent, the greater the test error will be.

[0008] Therefore, it is a technical problem that needs to be solved urgently to provide a tool for testing the low-temperature flexibility of waterproof coatings in the field of waterproof coatings. Summary of the invention

[0009] The utility model aims to provide a tool for testing the low-temperature flexibility of waterproof coatings, so as to achieve simple and efficient testing of multiple objects to be tested.

[0010] To achieve the above object, the solution of the present utility model is to provide a tool for testing the low-temperature flexibility of waterproof coatings, including: a first platform, a flexible material layer, and a base connected in sequence from top to bottom. The flexible material layer is provided with a test object, and the surface of the test object is coated with a waterproof coating. One end of the flexible material layer is fixed on the first platform, and the other end is fixed on the base; fixed clamps are respectively arranged on the left and right sides of the flexible material layer. The fixed clamps are used to fix the tooling rod. When the first platform bends around the tooling rod, the tooling rod causes the flexible material layer to be pulled and deformed between the first platform and the base, so as to perform a low-temperature flexibility test on the waterproof coating applied to the surface of the test object.

[0011] Further, the fixed clamp includes a slide rail and two clamping components. The clamping components can slide or be fixed on the slide rail, and the clamping components are used to clamp and fix the tooling rod.

[0012] Further, the clamping component includes a positioning plate and a fixing nail. The fixing nail is arranged at the lower part of the positioning plate.

[0013] Further, a threaded hole is provided at the bottom of the positioning plate, and the fixing nail has an external thread. The fixing nail is connected with the positioning plate in a matching manner. When it is necessary to fix the positioning plate, the fixing nail is tightened, and the fixing nail and the positioning plate clamp the slide rail.

[0014] Further, a plurality of clips are respectively arranged on the first platform and the base. The clips are used to fix the test object, so that the test object is fixed between the flexible material layer and the tooling rod.

[0015] Further, the clips on the first platform and the base correspond to each other, and multiple test objects can be clamped simultaneously.

[0016] Further, a handle is arranged on the first platform to facilitate the operation of the staff.

[0017] Advantages of the present utility model:

[0023] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0024] As Figure 1 and Figure 2 shown, a tool for testing the low-temperature flexibility of waterproof coating includes: a first platform, a flexible material layer 2 and a base 1 connected in sequence from top to bottom. The object to be tested 7 is arranged on the flexible material layer 2, and the surface of the object to be tested 7 is coated with waterproof coating. One end of the flexible material layer 2 is fixed on the first platform, and the other end is fixed on the base 1. Fixed fixtures 5 are respectively arranged on the left and right sides of the flexible material layer 2. The fixed fixtures 5 are used to fix the tooling rod 6. When the first platform bends around the tooling rod 6, the tooling rod 6 causes the flexible material layer to be pulled and deformed between the first platform and the base 1, so as to conduct a low-temperature flexibility test on the waterproof coating coated on the surface of the object to be tested 7. A handle 3 is arranged on the first platform to facilitate the operation of the staff. By pulling the handle 3, the flexible material layer and the object to be tested 7 are deformed around the tooling rod 6, so as to observe whether the object to be tested 7 breaks.

[0025] The fixed fixture 5 includes a slide rail 51 and two clamping components. The clamping components can slide or be fixed on the slide rail 51, and the clamping components are used to clamp and fix the tooling rod 6. The clamping component includes a positioning plate 53 and a fixing nail 52. The fixing nail 52 is arranged at the lower part of the positioning plate 53, and the fixing nail 52 slides or is fixedly connected to the slide rail 51. A threaded hole is arranged at the bottom of the positioning plate 53, and the fixing nail 52 has an external thread. The fixing nail 52 is cooperatively connected with the positioning plate 53. When it is necessary to fix the positioning plate 53, the fixing nail 52 is tightened, and the fixing nail 52 and the positioning plate 53 clamp the slide rail 51. By moving and fixing the clamping component on the slide rail 51, the tooling rod 6 is clamped and fixed to be applicable to tooling rods 6 with different diameters. The slide rail 51 is perpendicular to the axis of the tooling rod 6.

[0026] A number of clips 4 are respectively provided on the first platform and the base 1. The clips 4 are used to fix the object to be tested 7, so that the object to be tested 7 is fixed between the flexible material layer 2 and the tooling rod 6. The clips 4 on the first platform and the base 1 correspond one by one, and multiple objects to be tested 7 can be clamped simultaneously. The object to be tested 7 is a low-temperature object to be tested 7, and the tooling rod 6 is a low-temperature tooling rod 6. By clamping multiple objects to be tested 7, multiple objects to be tested 7 can be tested simultaneously. Multiple objects to be tested are bent under the same environmental and the same force conditions, which can increase the credibility of data parallelism and improve the test efficiency.

[0027] Specific working process:

[0028] First step: Place a number of low-temperature objects to be tested 7 one by one on the flexible material layer 2, and the clips 4 on the first platform and the base 1 fix both ends of the low-temperature objects to be tested 7.

[0029] Second step: Select a low-temperature tooling rod 6 with a suitable diameter and place it at the junction of the base 1 and the low-temperature object to be tested 7, and use the tooling rod 6 to press the low-temperature object to be tested 7. The tooling rod 6 is fixed by the fixing fixture 5. According to the diameter of the tooling rod 6, adjust the distance between the two clamping components, and then slide the fixing nail 52 on the slide rail 51 to a suitable position and tighten the fixing nail 52 to fix the position of the clamping component, thereby clamping the tooling rod 6.

[0030] Third step: Place this test tool device in a specified low-temperature environment.

[0031] Fourth step: As Figure 3 shown, after reaching the specified time, pull the handle 3 uniformly until it is parallel to the base 1 and then stop. The low-temperature object to be tested 7 and the flexible material layer 2 deform around the tooling rod 6.

[0032] Fifth step: Observe whether the low-temperature object to be tested 7 is broken and record the experimental data.

[0033] In some other embodiments, the tool for testing the low-temperature flexibility of waterproof coating further includes a driving motor, and the driving motor is fixed on the base 1 and connected to the first platform. By setting the driving motor, precise control of the bending angle can be achieved, so that the bending degree can be adjusted according to different test standards or material properties, improving the flexibility and accuracy of the test.

[0034] In some other embodiments, the tool for testing the low temperature flexibility of the waterproof coating further includes a sensor and a processor. The sensor is adapted to monitor the temperature, deformation amount and surface state of the object to be tested. The processor is electrically connected to the sensor, and the processor is adapted to record the monitoring results of the sensor and perform analysis and processing based on the monitoring results.

The processor can record and analyze the monitoring results of the sensor. For example, it can record the temperature and deformation amount when cracks occur in the object to be tested 7, so as to determine whether the object to be tested 7 is qualified, and further calculate the qualification rate, etc. Further, the processor includes a Bluetooth or Wi-Fi module to transmit the analysis results to a computer or a mobile device in real time, realizing the intelligence of the test process and the instant analysis of data.

[0035] In some other embodiments, the tool for testing the low temperature flexibility of the waterproof coating further includes a second platform, and the second platform is detachably connected to the first platform. By providing the second platform, the testing tool can be made to adapt to more sizes and shapes of the objects to be tested 7. Especially for larger or longer samples, the combination of the two platforms can provide more stable support and more uniform stress distribution, improving the applicability and accuracy of the test.

[0036] Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.
