Abstract

The invention relates to a mural and colored drawing cultural relic reinforcing agent with a self-healing function and a preparation method thereof, poly (2-ethyl-2-oxazoline) and poly(4-vinylphenol)are taken as main components, the reinforcing agent has good permeability to murals or colored drawing cultural relics, and the appearance of the reinforced cultural relics is not influenced. The reinforcing agent has a high-efficiency self-healing function in a humid environment with the normal temperature and the relative humidity of 80% or above, and the self-healing efficiency can reach 85% orabove. Besides, soluble salt calcium chloride or magnesium chloride is added, or calcium chloride or magnesium chloride contained in murals and colored drawing cultural relics can be coordinated withthe reinforcing agent, and self-healing can be better promoted. Compared with a common acrylic reinforcing agent, the reinforcing agent disclosed by the invention has higher bonding strength, the reinforcing effect is ensured, and meanwhile, the reinforcing agent can also be used as a cultural relic adhesive capable of being repeatedly bonded.

Description

Technical field

[0001] The invention belongs to the technical field of cultural relics protection, and relates to a mural and color-painted cultural relic reinforcement with self-healing function and a preparation method. Background technique

[0002] The protection of cultural relics is a common long-term issue worldwide. Reinforcement protection is to restore certain mechanical strength to murals and painted cultural relics by adding organic or inorganic materials to avoid devastating damage. Reinforcing agents for murals and painted cultural relics require a certain degree of flexibility, tensile strength, hardness, and adhesive properties (Sichuan Cultural Relics, 2003, 3, 94-96). At present, most cultural relics protection materials use solution-type polymer materials, which are usually used as adhesives, reinforcing agents and protective coatings, and the protection effect is fast and effective. However, not only cultural heritage, but these protective materials themselve...
