在修复宝蕴楼之前,了解其当时所用材料是非常必要的。本文研究了宝蕴楼门窗漆层的成分,所用方法是热裂解气相色谱质谱(Py—GC—HS)法、气相色谱质谱(GC—MS)法、扫描电镜能谱(SEH—EDS)法。分析结果显示:其漆层主要胶结材料为桐油和松香树脂,同时在底层发现使用猪血的现象;所用颜料:白色颜料为锌钡白,黑色为炭黑。与传统材料不同的是,门窗涂层材料用桐油和松香树脂代替大漆;而底层-腻子中测出了猪血,与中国古代传统建筑彩绘所用材料一致。从材料上反映出该建筑中西合璧的特征,本研究结论为文物修复工作提供了可靠的信息和科学依据。
It is very important to understand the materials used at the time before Bao Yun House was repaired. In this paper, the composition of Bao Yunlou door and window paint was studied. The methods used were pyrolysis gas chromatography mass spectrometry (GC-MS) and scanning electron microscopy (SEH-EDS). The results showed that the main cementing materials of the lacquer were tung oil and rosin resin, and the phenomenon of using pig blood was found on the bottom. The pigments used were white lithopone and black black carbon black. Different from the traditional materials, the door and window coating materials use tung oil and rosin resin instead of lacquer; while the bottom - putty measured in the blood of pigs, and ancient Chinese traditional architectural painting materials used. The characteristics of Chinese and western architecture of the building are reflected from the material. The conclusion of the study provides reliable information and scientific basis for the restoration of cultural relics.
