Abstract Preservation of ancient polychromic relics is imperative for providing rich historical information. Raw material consolidation has become a new trend for the protection of polychromic relics. A new material based on gelatin microspheres (GM) was developed in this work to overcome the issues associated with the sol-gel property of gelatin. Small particles were sprayed on the surface of a polychromic relic; these permeated to a certain depth and expanded in the presence of water to provide internal crosslinking and surface sealing. The GMs were obtained through emulsification-coacervation in a water-in-oil emulsion. The GMs were uniform in size and their purity was verified using SEM and FT-IR spectroscopy. The protective effect of this novel treatment on painted samples was evaluated and compared to a commonly used synthetic treatment (Paraloid B72) as well as a blank control. The surface performance, breathability, and durability of the GM treatment was superior to Paraloid B72. The GM treatment can be used for effective consolidation.

基于明胶微球的多色文物保护处理

摘要 古代多色文物的保存对于提供丰富的历史信息势在必行。原材料整合已成为多色文物保护的新趋势。在这项工作中开发了一种基于明胶微球 (GM) 的新材料，以克服与明胶溶胶-凝胶特性相关的问题。将小颗粒喷洒在多色文物的表面；它们渗透到一定深度并在有水的情况下膨胀以提供内部交联和表面密封。GMs是通过在油包水乳液中乳化-凝聚获得的。GMs 大小均匀，并且使用 SEM 和 FT-IR 光谱验证其纯度。评估了这种新型处理对涂漆样品的保护作用，并与常用的合成处理 (Paraloid B72) 以及空白对照进行了比较。GM处理的表面性能、透气性和耐用性优于Paraloid B72。GM 处理可用于有效巩固。
