Abstract In this paper, the mechanical property changes of polyurea coating including tensile strength and breaking elongation were studied, as well as surface state such as glossiness, and smoke density during 180 days of natural exposure. Furthermore, Fourier infrared spectroscopy, thermogravimetric analysis, scanning electron microscope and atomic force microscope were used to characterize the microstructure and morphology of the coating, and the mechanism of the change in the anti-aging performance of the coating under natural exposure was analyzed. The results showed that the mechanical properties such as tensile strength and breaking elongation of the coating decreased after exposure. The gloss and smoke density respectively decreased by 99.89% and 82.20%, while the wettability and thermal stability increased. After exposure, the coating surface cracked and the roughness increased. The exposure process has a great impact on the chemical structure of the coating. After exposure, the degree of microphase separation of the coating increases. Quantitative analysis of the infrared spectrum shows that the hydrogen bond length and the degree of hydrogen bond of the coating are reduced after exposure.

Key words： polyurea coating aging property smoke suppression performance microphase separation degree of hydrogen bonding roughness
