Abstract

The influence of weather conditions on the durability of acrylic-polyurethane car coatings during their exposure to industrial plants (Grupa Azoty, Zakłady Chemiczne "Police" SA) was investigated. The surface structure and the general appearance of the paint coatings (after 16 months of the test) were examined using an optical microscope and a scanning electron microscope, an optical profilometer and a gloss meter. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared spectroscopy (FTIR) were used to study the composition and chemical structure of the coatings. Convex spots of various sizes were observed on the surface of the tested coatings. Quantitative profilometric analysis showed a clear increase in surface roughness. However, the results of the XPS and FTIR tests did not confirm the chemical degradation of the tested samples. It was shown that the convexities observed on the surfaces of the aged coatings were atmospheric deposits consisting mainly of oxygen, calcium, phosphorus, iron, silicon and carbon. Thorough cleaning of the surfaces resulted in their complete removal.

某工业区气候条件对丙烯酸-聚氨酯汽车涂料耐久性的影响

天气条件对丙烯酸-聚氨酯汽车涂料暴露于工业工厂(Grupa Azoty, Zakłady Chemiczne“Police”SA)期间耐久性的影响进行了调查。使用光学显微镜和扫描电子显微镜、光学轮廓仪和光泽度仪检查油漆涂层的表面结构和总体外观(经过16个月的测试)。利用x射线光电子能谱(XPS)和傅里叶变换红外光谱(FTIR)研究了涂层的组成和化学结构。在被测涂层表面观察到不同大小的凸点。定量轮廓分析表明，表面粗糙度明显增加。然而，XPS和FTIR测试的结果并没有证实被测样品的化学降解。结果表明，老化涂层表面的凸起是大气沉积物，主要由氧、钙、磷、铁、硅和碳组成。彻底清洗表面使其完全去除。
