【摘要】：在歷經(jīng)兩千年埋藏以后,秦始皇兵馬俑表面的漆皮彩繪在出土?xí)r,大多會卷曲脫落。如何將漆皮彩繪回貼加固好一直是保護工作者研究的難點。本工作在秦帝陵博物院前期工作的基礎(chǔ)上,通過實驗室模擬研究探索了黏結(jié)、回貼過程中陶本體含水率、PEG含量、可溶鹽含量、陶塊泥土粘附量、漆皮彩繪含水率、PEG含量、臨時固型劑含量等對回貼、黏結(jié)效果的影響。結(jié)果表明將陶塊含水率降至5%以下、減少PEG200溶液滲入陶本體、對陶本體進行脫鹽處理、在黏結(jié)劑中添加極細小填料、逐漸增加PEG200濃度來潤濕漆皮、清除殘存的臨時固型劑薄荷醇等措施都能不同程度地改善漆皮彩繪回貼的效果,增加黏結(jié)強度,提高其耐老化破壞循環(huán)的能力。以上應(yīng)用基礎(chǔ)研究可以為彩繪類文物現(xiàn)場保護工藝的改進提供借鑒。
[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.
