However, the existing research on the performance of waterproof coatings only considers the influence of a single factor on their waterproof and durability performance, mainly focusing on the influence of water pressure on waterproof performance, while the temperature factor is rarely involved, and there is a lack of corresponding testing devices, which brings challenges and difficulties to the development of high-performance waterproof coatings.

[0004] Therefore, developing a waterproof performance testing device that can consider the multi-field coupling of temperature and force to optimize the design of high-performance waterproof coatings has become an urgent need in the current water conservancy industry. Content of the Utility Model

It realizes the testing of the waterproof performance of waterproof coatings under different temperature and pressure conditions.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A temperature-force multi-field coupling coating waterproof performance testing device, comprising:

[0008] A temperature adjusting member for adjusting the water temperature;

[0012] The test system is connected to the water tunnel system and tests the waterproof performance of the waterproof coating through the circulating water flow.

[0013] The air extraction pipeline is connected to the water tunnel system.

[0014] Preferably, a detector is further arranged on the water tunnel system, and the detector is used for detecting the water pressure in the water tunnel system.

[0015] Preferably, the test system includes a fixing frame, a test box arranged on the fixing frame, and connecting pipes connected to both sides of the test box.

[0016] The test box is formed by enclosing two side plates, a back plate, a top plate, a bottom plate and a test plate, and a temperature measuring element and a pressure measuring element are arranged on the inner side wall of the back plate.

[0017] Preferably, the two side plates, the bottom plate, the back plate, the fixing frame and the connecting pipes are made of stainless steel, and the top plate is made of tempered glass.

[0018] Preferably, the test plate includes a cement base and the waterproof coating coated on the surface of the cement base.

[0024] Due to the application of the above technical solutions, the beneficial effects of the present application compared with the prior art are as follows:

[0025] In the prior art, the research on the performance of waterproof coatings only considered the influence of a single factor, i.e., water pressure, on their waterproof and durability performance.

[0047] In some embodiments, the above-mentioned first pipeline 6, second pipeline 7, water inlet pipeline 8, and water tunnel system 3 are made of stainless steel.

[0048] The test system 4 is connected to the water tunnel system 3, and the waterproof property of the waterproof coating is tested through the circulating water flow. The test system 4 includes a fixing frame 41, a test box 42 provided on the fixing frame 41, and connecting pipes 43 connected to both sides of the test box 42.

[0049] Specifically, the test box 42 is formed by enclosing two side plates 421, a back plate 423, a top plate, a bottom plate 422, and a test plate 424. A temperature measuring member 30 and a pressure measuring member 40 are provided on the inner side wall of the back plate 423.

[0050] In some embodiments, the length of the inner cavity of the test box 42 is 120 mm, the width is 50 mm, and the depth is 50 mm.

[0051] In some embodiments, the two side plates 421, the bottom plate 422, the back plate 423, the fixing frame 41, and the connecting pipe 43 are made of stainless steel, and the top plate is made of tempered glass.

[0052] In some embodiments, the test plate 424 includes a cement base and a waterproof coating applied to the surface of the cement base.

[0053] In some embodiments, the test plate 424 is connected to the two side plates 421, the top plate, and the bottom plate 422 respectively by screws.

[0054] As described above, in order to improve the detection accuracy and prevent water from seeping into the interior of the cement base from the edge, the length of the test plate 424 is greater than the length of the inner cavity of the back plate 423, and the width of the test plate 424 is greater than the depth of the inner cavity.

[0060] The water flow temperature is adjusted to -5 - 50 °C through the temperature adjusting element, and the water pressure is adjusted to 0.1 MPa - 1.5 MPa through the booster pump; the waterproof rate of the waterproof coating is characterized by the change in the mass P of the test plate, and the calculation formula is as follows:

[0061] P = (M1 - M0) / M0 × 100, where M1 is the mass of the test plate after a certain water flow time, M0 is the original mass of the test plate, and the smaller the P value, the better the waterproof effect.

[0062] In some other embodiments, the waterproof coating can be directly removed, and the water seepage condition of the cement base can be observed with the naked eye.

[0063] Due to the application of the above technical solutions, the beneficial effects of this application compared with the prior art are as follows:

[0064] In the prior art, the research on the performance of waterproof coatings only considers the influence of a single factor, i.e., water pressure, on their waterproof and durability performance.

This breaks through the limitations of the prior art. Such multi-factor coupling tests are closer to the actual engineering environment, can more comprehensively evaluate the waterproof performance and durability of the coating, and then provide more reliable data support, which helps to better develop waterproof coating technology.

[0065] At the same time, by setting the height of the inlet branch pipe to be lower than that of the inlet main pipe, and the height of the pressure-reducing drainage branch pipe to be higher than that of the inlet branch pipe and the inlet main pipe, it is ensured that when the device is operating, the water flow can effectively be naturally transported from the inlet branch pipe to the water tunnel system by gravity. When the water pressure is too high, part of the water flow enters the pressure-reducing drainage branch pipe, and the gas can be discharged through the exhaust valve to reduce the water pressure, while the overflow valve can safely discharge the excess water to prevent the pipelines at various parts of the device from being damaged due to overpressure, thereby improving the use safety and reliability of the device.
