Coating storage stability testing device

The utility model provides a coating storage stability testing device, which comprises a testing box, a box cover and a sample storage assembly, and compared with the prior art, the coating storage stability testing device has the following beneficial effects that by arranging an observation window and the sample storage assembly, a user can directly observe the change of a coating sample in the testing box in the testing process through the observation window, so that the testing accuracy is improved; in this way, a tester can conveniently monitor and adjust the testing process, meanwhile, the xenon lamp in the testing box can provide a simulated sunlight spectrum with ultraviolet light and visible light and is used for testing the weather resistance of the coating in the outdoor environment, and by arranging a heating pipe and a ventilation assembly, the weather resistance of the coating can be improved. The test box is simple in structure and convenient to use, the temperature influence of the coating in t
