秦俑彩绘回贴影响因素的探索性研究
发布时间：2019-03-21 07:56
【摘要】：在历经两千年埋藏以后,秦始皇兵马俑表面的漆皮彩绘在出土时,大多会卷曲脱落。如何将漆皮彩绘回贴加固好一直是保护工作者研究的难点。本工作在秦帝陵博物院前期工作的基础上,通过实验室模拟研究探索了黏结、回贴过程中陶本体含水率、PEG含量、可溶盐含量、陶块泥土粘附量、漆皮彩绘含水率、PEG含量、临时固型剂含量等对回贴、黏结效果的影响。结果表明将陶块含水率降至5%以下、减少PEG200溶液渗入陶本体、对陶本体进行脱盐处理、在黏结剂中添加极细小填料、逐渐增加PEG200浓度来润湿漆皮、清除残存的临时固型剂薄荷醇等措施都能不同程度地改善漆皮彩绘回贴的效果,增加黏结强度,提高其耐老化破坏循环的能力。以上应用基础研究可以为彩绘类文物现场保护工艺的改进提供借鉴。
[Abstract]:After burial in 2000, the lacquer skin painted on the surface of Qin Shihuang terracotta warriors and horses will mostly curl and fall off when unearthed. How to strengthen the paint back is a difficult problem for the protection workers. Based on the previous work of Qin Emperor Mausoleum Museum, the moisture content, PEG content, soluble salt content, adhesion amount of clay block, painted water content and PEG content of lacquer skin in the process of bonding and reattachment have been studied by laboratory simulation and study on the basis of the previous work of Qin Emperor Mausoleum Museum. The effect of the content of temporary curing agent on the effect of back-bonding and bonding. The results showed that the moisture content of the ceramic block was reduced to less than 5%, the infiltration of PEG200 solution into the ceramic body was reduced, the ceramic body was desalted, the extremely fine filler was added to the binder, and the concentration of PEG200 was gradually increased to moisten the paint skin. Removal of the remaining temporary curing agent menthol and other measures can improve the effect of paint painting and retainer in varying degrees, increase the bonding strength, and improve its ability to resist aging and destroy the cycle. The above basic research can be used for reference for the improvement of the field protection technology of painted cultural relics.
