Description

Graphene oxide sealing and protecting method for iron cultural relics
Technical Field
The invention relates to a graphene oxide sealing and protecting method for an iron cultural relic, and belongs to the technical field of sealing and protecting of iron cultural relics.
Background
The iron cultural relics have important historical, artistic and scientific values and account for a large proportion of cultural relics collected in the library in China. However, if the chemical activity of iron and the structural characteristics of rusty objects are not protected under the condition of collection, further deterioration corrosion and even mineralization disintegration can be generated.
The protection process of the iron cultural relics generally comprises cleaning, derusting, desalting, inhibiting corrosion, reinforcing and sealing protection. The sealing layer improves the mechanical strength of the iron cultural relics to a certain extent, greatly slows down the speed of oxygen, moisture and other corrosion factors reaching the surface of the cultural relics, and avoids or delays the continued corrosion of the cultural relics. Therefore, the selection and optimization of the containment material is critical. The wax such as microcrystalline paraffin and insect white wax is applied earlier and more widely in the protection of iron cultural relics, but is only suitable for small utensils and is difficult to operate and use on large utensils due to process limitation. In addition, synthetic polymer materials such as nitro varnish, polyurethane, acrylic resin, fluorocarbon resin and the like are also applied to the sealing protection of iron cultural relics, but all have defects and cannot well meet the cultural relic protection principle. For example, the nitro varnish is fast to dry, hard and abrasion-resistant, but has poor adhesion; the polyurethane has good weather resistance and aging resistance, but is difficult to remove after curing; acrylic resin has good film forming property but insufficient corrosion resistance; the fluorocarbon resin has good corrosion resistance, but can generate glare after film forming. In order to promote the development of iron cultural relic protection materials, researchers apply organosilicon materials with excellent hydrophobicity to the sealing and protection of iron cultural relics, but the organosilicon film layer often contains micropores and has poor corrosion resistance. At the same timeThe addition of nano-filler to the original sealing and protecting material also becomes a research trend, and researchers have led to the introduction of nano-SiO 2 TiO 2 nanoparticles 2 The powder is added into the acrylic emulsion, so that the hydrophobicity, the acid and alkali resistance and the like of the sealing layer can be improved, but the unmodified nano powder is directly added into the coating, so that the dispersion is not uniform, and the sealing and protecting effect is greatly reduced.
