丙烯酸树脂B72丙酮溶液在陶瓷文物修复中应用比例研究

Study of application proportion of Paraloid B72 in acetone for the restoration of ceramics

作为加固剂和封护剂,丙烯酸树脂B72(简称B72)是国内外应用极其广泛的文物保护修复材料,但作为黏接剂在陶瓷修复粘接、补全、涂层饰色流程中的应用比例及范围几乎未见相关研究实例。文章梳理了B72材料性能和配制方式,通过不同比例B72丙酮溶液固化及作业时间和应用状态实验,提出其作为黏接剂在陶瓷文物粘接、补全、涂层饰色修复流程中的应用比例标准、适用范围和配方比例。研究结果可为文物保护者提供B72简便高效的应用甄选方案。

Paraloid B72 is widely used as a consolidation and sealing material for the conservation and restoration of cultural relics at home and abroad.However,there is almost no relevant discussion of proportions and scope of application as adhesives in the process of bonding,filling and coating-painting of ceramics.This article describes material properties and preparation methods of B72,and proposes standard of application proportions,the scope of application and formulations with talc for use as adhesives in the process of bonding,filling and coating-painting of ceramics,based on tests of set and working time and application conditions with different proportions of B72 in acetone.It provides simple,efficient and available application cases of B72 for conservators.
