研究了含氟丙烯酸酯聚氨酯(FPA)涂层和丙烯酸酯聚氨酯(PA)涂层暴露在模拟自然环境(紫外光、酸雨、灰尘)中的防沾污性能。结果表明,FPA 涂层的防沾污性能在暴露初期优于 PA 涂层,且随着环境暴露时间的延长防沾污性能逐渐下降。根据两种涂层在模拟自然环境中的表面光泽度、接触角及滚动角的变化特点,初步分析探讨了这两种涂层的防沾污失效机制,发现疏水性的FPA涂层与亲水性的 PA 涂层在模拟自然环境中的防沾污失效机制上存在着差异。
The study aims to explore the anti-staining property of fluorine-modified polyurethane-acrylic coatings (FPA)and polyurethane-acrylic coatings (PA)in simulated natural environmental (UV light,acid rain,dust). The results show that FPA coatings’anti-staining property was better than that of PA coatings at the early stage of exposing time but declines gradually.The analysis of failure mechanism was based on the results of three relevant surface properties:glossness,contact angle and sliding angle,which suggest that the failure mechanism of anti-staining property of hydrophobic FPA coatings differs from that of hydrophilic PA coatings.
