[0007] To achieve the above purpose, the utility model adopts the following technical solution:

[0008] A coating weather resistance testing device includes a coating plate coated with a coating, a testing box for spraying water on the coating plate for testing, and a water tank located on the ground. A water filling pipe convenient for adding water is fixedly arranged at the top of the water tank, and a tightening cap is threadedly connected to the water filling pipe. A box body is arranged in the testing box, and a plurality of spray heads for spraying water are fixedly arranged on one side of the box body and are communicated. The same first placing rack for placing the coating plate is fixedly arranged on the inner walls of both sides of the testing box, the first placing rack is adapted to the coating plate, and the coating plate is placed in the first placing rack;

[0009] A conveying mechanism, which is arranged in the test box and used for conveying the water in the water tank;

[0010] A moving mechanism, which is arranged in the test box and used for moving multiple nozzles to expand the spraying range;

[0011] A high-temperature mechanism, which is arranged on one side of the test box and used for heating and baking the coating plate.

[0012] In a possible design, the conveying mechanism includes a water pump, a first pipeline and a telescopic hose. A support plate is fixedly arranged on the inner wall of one side of the test box. The bottom of the water pump is fixedly connected to the top of the support plate. One end of the first pipeline is fixedly connected to the input port of the water pump. The other end of the first pipeline penetrates through one side of the test box and is fixedly connected to and communicated with one side of the water tank. One end of the telescopic hose is fixedly connected to the output port of the water pump. The other end of the telescopic hose is fixedly connected to and communicated with one side of the box body.

One side of the motor is fixedly connected to the inner wall of one side of the cover body. One end of the lead screw is fixedly connected to the output end of the motor. The other end of the lead screw is rotatably connected to the inner wall of one side of the cover body. The top of the moving plate is slidably connected to the inner wall of the top of the cover body. A lead screw nut is embedded in one side of the moving plate. The lead screw nut is threadedly connected to the lead screw. The bottom of the moving plate is fixedly connected to the top of the box body.

[0014] In a possible design, the high-temperature mechanism includes a high-temperature box, an electric heating plate and a second placement rack.

Open the first cover of the test box, place the application board coated with paint on the first placement rack in the test box, and close the first cover to prevent water from splashing during the test. Start the water pump, so that the water in the water tank is transported into the box body through the first pipe and the telescopic hose, and the water is sprayed out through the nozzle in the box body to conduct a water spray test on the application board, simulating the effect of rain erosion. If it is necessary to expand the spraying range, start the moving mechanism. The motor drives the screw rod to rotate. Through the threaded connection between the screw rod nut and the moving plate, the moving plate drives the box body and the nozzle to move horizontally, thereby expanding the water spray range (the motor is a stepping motor). During this process, the valve on the drain pipe needs to be opened for drainage. After the water spray is completed, take out the application board, and the application board can be compared with the coating sample before baking to observe whether it fades and whether the gloss changes, and then record the test results. When high-temperature testing is required, place the application board on the second placement rack in the high-temperature box, close the second cover of the high-temperature box, start the electric heating plate to increase the temperature in the high-temperature box, and conduct high-temperature baking on the application board (within the specified time and at the specified temperature), simulating the paint performance in a high-temperature environment. After the high temperature ends, take out the baked application board and place it at room temperature to cool naturally. Compare it with the application board before high-temperature baking, check the color and gloss of the paint, evaluate the heat resistance of the paint, and record the test results. During the entire test process, personnel can record the changes of the paint under different conditions, such as color, gloss, cracks, etc. Among them, the temperature of the electric heating plate can be controlled by an external controller, and the materials of the test box and the first cover are transparent glass or transparent acrylic materials.
