Abstract

Purpose

The color painting of ancient buildings has high historical and artistic value but is prone to aging due to long-term outdoor exposure. The purpose of this study is to develop a new type of sealing coating to mitigate the impact of ultraviolet (UV) light on color painting.

Design/methodology/approach

The new coating was subjected to a 500-h UV-aging test. Compared with the existing acrylic resin Primal AC33, the UV aging behavior of the new coating, such as color difference and gloss, was studied with aging time. The Fourier infrared spectra of the coatings were analyzed after the UV-aging test.

Findings

Compared with AC33, the antiaging performance of SF8 was substantially improved. SF8 has a lower color difference value and better light retention and hydrophobicity. The Fourier transform infrared spectroscopy results showed that the C-F bond and Si-O bonds in the resin of the optimized sealing coating protected the main chain C-C structure from degradation during the aging process; thus, the resin maintained good stability. The hindered amine light stabilizer TN292 added to the coating inhibited the antiaging process by trapping active free radicals.

Originality/value

To address the problem of UV aging of oil-decorated colored paintings, a new type of sealing coating with excellent antiaging properties was developed, laying the foundation for its demonstration application on the surface of ancient buildings.

彩绘文物新型密封涂层的抗老化性能研究

目的古建筑彩画具有很高的历史和艺术价值，但由于长期暴露在户外，容易老化。本研究旨在开发一种新型密封涂料，以减轻紫外线（UV）对彩画的影响。与现有的丙烯酸树脂 Primal AC33 相比，研究了新涂料的紫外线老化行为，如色差和光泽度随老化时间的变化。结果与 AC33 相比，SF8 的抗老化性能大幅提高。SF8 的色差值更低，保光性和疏水性更好。傅立叶变换红外光谱结果表明，优化密封涂层树脂中的 C-F 键和 Si-O 键保护了主链 C-C 结构在老化过程中不发生降解，因此树脂保持了良好的稳定性。原创性/价值针对油饰彩画紫外线老化的问题，开发了一种具有优异抗老化性能的新型密封涂料，为其在古建筑表面的示范应用奠定了基础。

期刊介绍： Anti-Corrosion Methods and Materials publishes a broad coverage of the materials and techniques employed in corrosion prevention. Coverage is essentially of a practical nature and designed to be of material benefit to those working in the field. Proven applications are covered together with company news and new product information. Anti-Corrosion Methods and Materials now also includes research articles that reflect the most interesting and strategically important research and development activities from around the world. Every year, industry pays a massive and rising cost for its corrosion problems. Research and development into new materials, processes and initiatives to combat this loss is increasing, and new findings are constantly coming to light which can help to beat corrosion problems throughout industry. This journal uniquely focuses on these exciting developments to make essential reading for anyone aiming to regain profits lost through corrosion difficulties. • New methods, materials and software • New developments in research and industry • Stainless steels • Protection of structural steelwork • Industry update, conference news, dates and events • Environmental issues • Health & safety, including EC regulations • Corrosion monitoring and plant health assessment • The latest equipment and processes • Corrosion cost and corrosion risk management.
