A reinforcing agent for the protection of ancient paper cultural relics and its use and preparation method

Abstract

The invention discloses a reinforcing agent for the protection of ancient paper cultural relics, which comprises: bletilla striata gum saturated aqueous solution and trehalose; the mass percentage of the bletilla striata gum saturated aqueous solution and the trehalose is 100: (2-3), It can reinforce the ancient paper cultural relics without changing the appearance of the cultural relics, and will not cause secondary damage. It is non-toxic, easy to operate, high in curing and bonding, and has a good reinforcement effect, making the ancient paper cultural relics resistant to preservation. Adding a small amount of water-soluble antifungal agent to the subsequent reinforcing agent can well solve the problem that polysaccharides are prone to mold. The invention also discloses a using method and a preparation method of a reinforcing agent for the protection of ancient paper cultural relics.

Description

technical field [0001] The invention belongs to the technical field of protection and restoration of paper cultural relics, and relates to a reinforcing agent for the protection of ancient paper cultural relics, a method for using the reinforcing agent for the protection of ancient paper cultural relics, and a method for the protection of ancient paper cultural relics. The preparation method of the reinforcing agent. Background technique [0002] Paper is widely used in people's life. In addition to common writing and painting, it can also be used as postage products, bills, archives, handicrafts, etc. According to the results of the first national survey of movable cultural relics, it is conservatively estimated that there are more than 21 million paper cultural relics in my country, accounting for 33.78% of all movable cultural relics, and paper cultural relics account for 27.15% of precious cultural relics, which is the largest category. Compared with metal, wood, and ce...

Problems solved by technology

[0003] However, the current reinforcement technology has its corresponding limitations: the backmounting method is a traditional paper reinforcement technology, and its use is limited. It can only be used for cultural relics printed on one side, and it is consistent with the basic principles of cultural relics protection. The concept does not match; although the silk screen reinforcement method has a better reinforcement effect, the silk has a serious impact on the covering of the paper with blurred writing. In addition, the silk is easy to age and harden, and at the same time it will cause the chain aging of the paper it protects; the principle of the hot pressing film method is Use a resin film to isolate the paper from the outside world, but this method will change the texture, appearance and thickness of the paper itself, and it is extremely difficult to process after the film is covered; the vacuum filming method is to introduce polymer monomers under vacuum conditions. Penetrating on the surface of paper to form a double-layer protective layer on the front and back, but this method requires high equipment and raw material costs, the operation is more complicated, and the thickness of the film is not easy to control; polymer glue coating and filming use one or more raw materials , formulated into a certain concentration of resin solution and then coated on the paper surface, but due to the poor permeability and wettability between the polymer material and the fiber, it cannot penetrate into the fiber well, and it is easy to be on the surface of the paper cultural relics and The internal concentration gradient is poor, thereby accelerating the aging of paper cultural relics; radiation reinforcement technology is a new type of paper protection technology, which mainly uses radiation to trigger the cross-linking and polymerization of polymer monomers attached to the paper, but the impact of radiation on paper has not yet been determined. Do books of certain materials have side effects?
