| 目的 提高海洋环境下具有指示作用的金属构件的防腐性能及夜间辨识度。方法 将硬脂酸改性发光颗粒与疏水高岭土和疏水二氧化硅颗粒均匀分散在环氧树脂中，用刷涂法将涂料刷在碳钢表面，待其固化后得到涂层。通过傅里叶变换红外光谱(FT-IR)、X射线光电子能谱(XPS)、X射线衍射(XRD)和热重分析(TGA)方法分析改性发光颗粒的化学成分，用接触角测量仪、SEM、LSCM测试和观察涂层表面的润湿性及微观形貌，通过砂纸磨损、盐雾和EIS测试涂层的耐磨性能和防腐性能，并借助屏幕亮度计测试涂层在盐雾试验前后的发光强度。结果 发光颗粒经过硬脂酸处理后在表面覆盖形成了疏水层。当涂层中的疏水高岭土颗粒与改性发光颗粒的质量比为1∶4时，涂层经过20次的磨损循环后仍具有超疏水性，且涂层质量仅损失了10.79%，该涂层在经过60 d的盐雾测试后，其阻抗保持在1010 Ω.cm2以上。在经过15次的干湿循环后，涂层体系的阻抗降至2.4×109 Ω.cm2，经过60 d盐雾测试后涂层的发光强度降至0.22 cd/m2。结论 通过硬脂酸改性提高了发光颗粒在水环境中的发光持久性，制备的涂层具有较好的疏水性和优异的耐磨性。在涂层中添加疏水高岭土颗粒提高了涂层的防腐性能，涂层防腐性能的提高使得涂层保持了良好的余辉性能。该涂层的性能研究为特殊海洋环境下金属类指示构件的防腐和夜间发光辨识提供了依据。 |

| Luminescent particles possess the attributes of non-electrical luminescence, environmental friendliness, and remarkable endurance, thereby bestowing immense significance in the domains of imaging, sensing, display, and warning. Adding luminescent particles to organic resins can endow marine environmental indicator materials with the ability to be visible at night. Moreover, the luminescent particles can be filled into the pores of the coating to isolate corrosion factors, thus improving the corrosion resistance of the coating. However, the application of luminescent particles in marine coatings is limited due to their insufficient abrasion resistance and compatibility, which leads to damage and failure of the coating surface. An effective way to solve this problem is to endow luminescent particles with superhydrophobic properties. The rapid rolling of water droplets on surface endow the materials with self-cleaning, waterproofing, chemical protection and other desirable properties. Therefore, hydrophobic treatment of luminescent particles and compositing with organic resin to form a warning superhydrophobic coating to protect the surface of carbon steel is beneficial for expanding the application field of luminescent materials and improving their adaptability and durability in harsh environments. In this paper, the luminescent particles were modified by stearic acid, and then, FT-IR, XPS, XRD and TGA were employed to analyze the chemical composition of the modified luminescent particles. The successfully modified luminescent particles were uniformly dispersed in the epoxy resin solution with hydrophobic kaolin and hydrophobic silica particles. The mixed solution was then brushed onto the carbon steel surface, and the target coating was obtained after curing. The effects of different particle ratios on the luminescence and hydrophobic properties, as well as on the wettability, abrasion resistanc and corrosion resistance of the modified composite coatings were investigated. The wettability and micromorphology of the coating surface were tested and observed by contact angle measurement, SEM and LSCM, respectively. The wear resistance and corrosion resistance of the coatings were tested by sandpaper abrasion, salt spray and EIS, respectively. The change of luminescence intensity of the coatings before and after salt spray was tested with a screen luminometer. When the mass ratio of hydrophobic kaolin particles to modified luminescent particles in the coating was 1∶4, the best effect was achieved. At this ratio, the coating still maintained superhydrophobic after 20 wear cycles, with only a mass loss of 10.79%. The impedance of the coating remained above 1010 Ω.cm2 after 60 days of salt spray test, and the impedance of the coating decreased to 2.4×109 Ω.cm2 after 15 wet and dry cycles. The results of EIS indicated that the coating had good salt spray resistance and dry-wet cycle resistance. After 60 days of salt spray test, the coating containing the highest proportion of modified luminescent particles could maintain high luminescence intensity with minimal reduction in luminescence intensity. In summary, the modification of luminescent particles with stearic acid improves their luminescent durability in aqueous environments. The coating prepared after compositing with organic resin has good hydrophobicity and excellent wear resistance, and thus has good anti-corrosion performance. The preparation and research of this coating are expected to provide reference and assistance for the long-term and effective application of metal based indicator markers in special marine environments. |
