| 目的 在较短的时间内获得有机涂层在沙漠大气环境下的腐蚀失效规律。 方法 针对有机涂层中应用比较广泛的丙烯酸聚氨酯涂层,采用紫外暴晒与吹沙试验相结合的加速试验环境谱进行实验室模拟沙漠大气环境加速老化试验,通过分析涂层质量、厚度、光泽度、表面形貌及电化学阻抗的变化,研究有机涂层的老化失效过程。 结果 随着加速试验周期的延长,丙烯酸聚氨酯涂层发生了一系列变化,表现为涂层质量减小,厚度减薄,光泽度降低,表面微观缺陷增多,电化学低频阻抗模值减小,防护性能下降。 结论 通过加速试验,可以快速获得有机涂层在沙漠大气环境下的老化失效规律。 |

| Objective To get the law of failure of the organic coating in the desert atmospheric environment in a relatively short period of time. Methods Acrylic polyurethane coating which is widely used in organic coatings was selected in the test, the accelerated aging test of the organic coating in desert atmospheric environment was carried out using the method of UV exposure and blowing sands test in the laboratory, and the aging process of the organic coating was characterized by changes in coating mass, thickness , gloss, the surface morphology and the electrochemical impedance. Results It turned out that the organic coating began to degrade with the decrease of mass, gloss, thickness and impedance but the increase of micro defects which implied the decrease of coating protective properties with time. Conclusion The law of degradation of the organic coating in desert atmospheric environment could be quickly obtained by accelerated test. |
