广西富川百柱庙建筑彩绘的保护修复研究

广西富川百柱庙为明朝修建，该建筑物建筑构件的型式、彩绘、斗拱的制作技法等保留了典型的地方民族风格，是研究古代瑶族历史的重要实物资料，但已年久失修。为了对该建筑进行维修，特别是对建筑内彩绘进行加固修复工作，应用XRD和FT-IR方法分析了彩绘颜料层的化学成分，结果表明全部为无机矿物颜料。以古建筑保存环境和彩绘层颜料化学成分为依据，通过现场实验确定用3％的Paraloid B～72丙酮溶液对彩绘层加固，结果表明该加固剂的渗透性、均匀性、加固强度都达到了对彩绘物的修复要求，加固后彩绘的颜色也较前鲜艳、明亮。

Research on protection and restoration of colored paintings in Baizhu Temple, Fuchuan, Guangxi province

The Baizhu Temple, built in Ming Dynasty in Fuchuan, Guangxi Zhuang Autonomous Region, boasts strong local style in terms of its building components, colored paintings and structures of Dougong. It is rated as an important material for studying the history of the ancient Yao nationality. However,it has not been repaired or rebuilt for many years. In order to repair this temple especially to reinforce and restore the colored paintings in the building, the pigments are analyzed with XRD and FT - IR methods and the result shows that all the chemical compositions are inorganic minerals. Considering the preservative environment for historic buildings and the chemical compositions of the coloured paintings, it is decided to use the Paraloid B - 72 acetone solution in 3% concentration as the consolidator of paintings. Field experiment proved that this consolidator was able to meet the demands of the restoration of ancient colored paintings either in its permeability, homogeneity or intensity. The result shows that the colors of the paintings became brighter and more brilliant after being reinforced.
