This study incorporates artificial accelerated aging experiments into the testing of stain resistance performance of exterior wall coating test panels,and then compared the data with conventional stain resistance test panels.The results indicate that the stain resistance of samples with good resistance to artificial climate aging hasn't change much after artificial accelerated aging test.Samples with obvious discoloration after aging test have poor stain resistance,and surface pulverization and other phenomena can also cause a decrease in stain resistance.The current stain resistance detection methods can't fully simulate the stain resistance in practical application scenarios,and improvement ideas have been proposed to provide reference for the revision of relevant method standards.
