一种新型复合封护剂的性能研究

该文研究一种应用于铁器文物保护的复合封护剂。该复合封护剂采用纯丙乳液作为基料，选用合适的分散剂，将纳米TiO2和SiO2均匀地分散在基料中，添加合适的助剂制成铁器文物的表层封护剂；选择一种高效的缓蚀剂，适量地添加到基料中，作为铁器文物的底层封护剂。根据铁器文物的保护要求对这种复合封护剂的主要性能进行了测试，并与未改性的纯丙乳液的封护性能进行了对比，发现这种复合封护剂在紫外屏蔽、耐蚀性及耐污染等方面有显著改善。这种复合封护剂无色、透明、无毒、无味，有锈无锈表面均可使用，可以作为一种新的环保型封护剂用于铁器文物的保护。

Study on the Composite Protective Agent for Iron Artifacts

An efficient composite protective agent for iron artifacts was studied and its main performances were tested under the requirement of the conservation for iron cultural relics in the paper. The nano-material was dispersed in the pure acrylic emulsion to form nano-composites. Nano-composites were used as top coat and pure acrylic emulsion added corrosion inhibitor was used as bottom coat in the conservation for iron artifacts. It was found that the composite protective coatings performed well in many properties, such as ultraviolet shield, resistance to pollution. The composite protective agent is promising in the conservation for iron artifacts.
