Technical Field

[0001] The utility model relates to the technical field of test chambers, and particularly relates to a climate aging test chamber for waterborne damping coatings. Background Art

[0002] The ultraviolet aging test chamber uses fluorescent ultraviolet lamps as light sources, and accelerates the weather resistance test of materials by simulating the ultraviolet radiation and condensation in natural sunlight to obtain the results of the weather resistance of materials. It can simulate environmental conditions such as ultraviolet, rain, high temperature, high humidity, condensation, and darkness in natural climate. By reproducing these conditions, they are combined into a cycle and it is allowed to automatically execute the number of cycles.

[0003] Common aging test chambers cannot simulate the water vapor environment in the natural environment, can only perform a single ultraviolet pretreatment test, and cannot adjust the light and shade of the coating during the light exposure, resulting in a large deviation in the obtained results of weather-resistant materials. Therefore, those skilled in the art have provided a climate aging test chamber for waterborne damping coatings to solve the problems raised in the above background art. Content of the Utility Model

The lower end of the arc-shaped shunt pipe is connected with a corrugated hose. The rear end of the lower box body is fixedly installed with a water tank. After the corrugated hose penetrates into the inner part of the shell of the lower box body, it is communicated with the water tank. The water in the water tank is pressurized by a water pump, so that the water liquid is atomized through the atomizing nozzles to supplement water for the coating during the aging test process. A water injection pipe is installed at the left end of the water tank.

[0005] Preferably: A number of screw heightening feet are provided on the lower end surface of the lower box body, and the levelness of the lower box body is adjusted by rotating the screw heightening feet to reduce the accumulation of the coating during the test and the residual water supplement, resulting in test errors.

[0007] Preferably: A transparent window is provided at the front end of the lower box body to facilitate observing whether the coating test process is normal during the test.

[0008] Preferably, a bottom groove is formed in the lower box body, and a plurality of limiting sliding grooves are equidistantly formed in the side end wall of the bottom groove. A limiting sliding block is arranged in the limiting sliding groove, and the same test groove table is connected between the left and right symmetric limiting sliding blocks at the same height, so that the test coating can be evenly smeared into the test groove table. A plurality of reciprocating lead screws are vertically arranged on the left side in the bottom groove, and the reciprocating lead screws are in threaded engagement with the test groove table at the same height.

A plurality of limiting sliding grooves 15 are equidistantly opened on the side end wall surface of the bottom groove 13. A limiting sliding block 17 is arranged in the limiting sliding groove 15. The same test groove table 16 is connected between the left and right symmetric limiting sliding blocks 17 at the same height, so that the test coating can be evenly smeared into the test groove table 16. A plurality of reciprocating lead screws 18 are arranged vertically and arranged on the left side in the bottom groove 13. The reciprocating lead screws 18 are threadedly engaged with the test groove table 16 at the same height. A meshing tooth 19 is fixedly installed at the rear end of the reciprocating lead screw 18. The adjacent meshing teeth 19 are meshed with each other. The uppermost meshing tooth 19 is fixedly connected with the output shaft of the rear servo motor 20, so as to synchronously drive the rotation of the reciprocating lead screw 18 on the meshing tooth 19 by using the servo motor 20;

[0019] An arc-shaped ultraviolet lamp panel 6 is fixedly installed at the lower end inside the box cover 3 by bolts.
