Adhesives for the Restoration of Chinese Paper 豆漿水等粘合劑在中國畫修復上的應用研究

Chinese mounting techniques have developed over hundreds of years, and are one of the important reasons for the long preservation of ancient painting and calligraphic works. To improve the stability of paper with water and avoid the bleeding of pigment when cleaning and inpainting, the glue-alum is normally used. But with prolonging of the aging time, the degradation of the paper is obvious. Following a technique recorded in ancient documents, the conservators tried soy milk instead of glue-alum. The physical properties, degree of polymerization, surface morphology and chemical structure changes were noted. The results showed that more hydrogen bonds formed between the paper surface and soy milk and the paper was more water-resistant.The degree of polymerization of the paper treated with soy milk decreased less than paper treated with glue-alum. The images of scanning electron microscopy shows the gel layer formed on the paper fibre surface.The soy milk can be used easily and has good effects. This study provides information for further use of soy milk in conservation.

Xu Wenjuan is the senior researcher in Shanghai Museum. She has worked there since 2002 after received her master degree. She has participated in the training project “Sina-Italy Cooperative Training Program on Cultural Relics Conservation & Restoration(Ⅱ)” and “International Course on Conservation of Japanese Paper organized by ICCROM. Her main interests are the preservation and restoration of paper-based and silk-based artifacts and the preventative environment research of cultural relics preservation. She obtained deep knowledge of the mounting materials of Chinese painting and calligraphic and Chinese hand-made paper g through her literature and field research.
