[0025] Embodiment 1

[0026] As Figures 1 to 3 shown, a rainproof performance testing device for exterior wall coatings includes a test operation table 1. A rainwater simulation component 2 is installed on the top of the test operation table 1, a moving control component 3 is connected inside the test operation table 1, and a drying adjustment component 4 is arranged on the side of the test operation table 1. The rainwater simulation component 2 includes a water storage bucket 201, a connecting pipe 202, a circulation pipe 203, a leakage hole 204, a fixed seat 205, a threaded rod 206, and a blocking ball 207. The rainwater simulation component 2 can accurately evaluate the rain resistance of the coating in actual use by simulating the process of natural rainfall. The leakage hole 204 forms a communication structure with the water storage bucket 201 through the circulation pipe 203 and the connecting pipe 202, and the threaded rod 206 is threadedly connected to the fixed seat 205. By injecting water into the water storage bucket 201, and then rotating the threaded rod 206 to open the pipeline of the connecting pipe 202, the water in the water storage bucket 201 will leak out from the leakage hole 204 through the connecting pipe 202 and the circulation pipe 203, thus simulating natural rainfall. By simulating the process of natural rainfall, the rain resistance of the coating in actual use can be evaluated more accurately. When rotating the threaded rod 206, the water flow rate can be controlled, and thus different intensities of rainfall can be simulated, so that the rainproof performance of the coating under different conditions can be tested.

[0027] As Figure 1 And Figure 4As shown, a rainproof property testing device for exterior wall paint, an air-drying adjustment component 4, includes a mounting frame 401, a slide slot 402, a control block 403, a control seat 404, a locking screw 405, a rotating ball 406, and a fan 407. The fan 407 provided in the air-drying adjustment component 4 can simulate the wind in the natural environment, and can more realistically test the drying process and performance of the paint under wind conditions. The fan 407 forms a rotating structure with the control seat 404 through the rotating ball 406, and the rotating ball 406 forms a threaded detachable structure with the control seat 404 through the locking screw 405, and The control seat 404 forms a sliding structure through the control block 403, the slide groove 402 and the mounting frame 401; by providing the fan 407, the fan 407 can simulate the wind in the natural environment, and can more realistically test the drying process and performance of the paint under wind conditions. At the same time, the fan 407 can accelerate the evaporation of water on the surface of the paint and shorten the drying time of the paint. The fan 407 can adjust the angle by rotating the ball 406. In addition, the fan 407 can slide in the slide groove 402 through the control block 403, so that the fan 407 can be adjusted to a suitable angle and position as needed.

[0028] like Figure 1 and Figure 5 As shown, a rainproof property testing device for exterior wall coatings, a movable control component 3, includes a mounting seat 301, a ball bearing 302, a snap-fit ​​seat 303, and a slider 304. The movable control component 3 facilitates water to be poured onto all positions of the test board. The ball bearing 302 forms a rotating structure with the mounting seat 301 through the snap-fit ​​seat 303, and the mounting seat 301 forms a sliding structure with the rainwater simulation component 2 through the slider 304. The exterior wall waterproof coating is applied to a test board, and the test board is placed on the snap-fit ​​seat 303. The snap-fit ​​seat 303 can then be rotated so that water can be poured onto all positions of the test board. In addition, the ball bearing 302 is provided to make the snap-fit ​​seat 303 rotate more smoothly.

[0029] Working principle: First, apply the exterior wall waterproof coating on a test board and place the test board on the clamping seat 303. At this time, fill the water storage bucket 201 with water, and turn the threaded rod 206. At this time, the threaded rod 206 will drive the blocking ball 207 to move into the fixed seat 205, thus opening the pipeline of the connecting pipe 202. At this time, the water in the water storage bucket 201 will leak out from the leakage hole 204 through the connecting pipe 202 and the flow pipe 203, so that the water will pour on the test board at the bottom, thereby simulating rain, and the waterproof performance of the waterproof coating on the test board can be detected. At the same time, the relative position of the blocking ball 207 and the connecting pipe 202 can be controlled by turning the threaded rod 206, so that the water flow can be controlled, and different degrees of rain conditions can be simulated. Then, when simulating rain through the rain simulation component 2, the position and angle of the test board placed on the clamping seat 303 can be adjusted by rotating the clamping seat 303 and sliding the mounting seat 301, so that each position of the test board can be wetted by water, ensuring the accuracy of the waterproof performance of the coating;

[0030] Next, after simulating rain pouring for a period of time, tighten the threaded rod 206 to close the pipeline of the connecting pipe 202. At this time, the waterproof condition of the coating on the test board can be checked. Then, turn on the switch of the blower 407 to use the blower 407 to dry the moisture of the coating on the test board. After drying, the test can be carried out again, simulating the situation where the exterior wall is wetted by rain and then dried naturally and then wetted by rain again. At the same time, when using the blower 407 to dry the moisture on the coating, the blower 407 can be rotated through the rotating ball 406 to adjust the angle of the blower 407. After the angle is adjusted properly, the angle of the blower 407 can be fixed by tightening the locking screw 405, and the position of the blower 407 can be controlled by sliding the control block 403, so that the moisture of the coating on the test board can be fully dried.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
