Multifunctional nano compound treating fluid for protecting paper cultural relics and preparation method thereof

Abstract

The invention discloses multifunctional nano compound treating fluid for protecting paper cultural relics. The multifunctional nano compound treating fluid takes deionized water as a solvent, and comprises nano magnesium hydroxide, nano titanium dioxide and hydroxyethyl cellulose, wherein nano magnesium hydroxide accounts for 0.2-1.0% of the weight of deionized water, nano titanium dioxide accounts for 0.1-0.8% of the weight of deionized water, and hydroxyethyl cellulose accounts for 0.2-0.8% of the weight of deionized water. The invention also discloses a preparation method of the multifunctional nano compound treating fluid. The multifunctional nano compound treating fluid can be used for large-area treatment of the paper cultural relics, and can be used for providing protection for deacidification, solidification, light-resistant degradation and mould proofing of the paper cultural relics during a large-area treatment of the paper cultural relics. The pH value of the paper cultural relics treated by the multifunctional nano compound treating fluid can reach an alkalescence degree, and the paper cultural relics have a certain alkali residue, can resist external acid, can be greatly improved in tensile strength, and have a certain antibacterial property.

Description

technical field [0001] The invention relates to a treatment liquid for paper cultural relics, in particular to a multifunctional nano-composite treatment liquid which can be used for large-area treatment of paper cultural relics and a preparation method thereof. Background technique [0002] As an important medium for recording and inheriting human culture, paper cultural relics are now under severe damage from acidification, oxidation, biocorrosion and photo-induced degradation. Paper cultural relics are generally made of paper, which is suffering irreversible damage as time goes by. In response to this situation, library and cultural relic management workers in various countries have taken a series of actions. At present, there are many large-scale deacidification methods for deacidification protection of paper cultural relics, and some of them have been commercialized. There are some controversies about some existing deacidification methods, which mainly focus on the fa...

Problems solved by technology

There are some controversies about some existing deacidification treatment methods, which mainly focus on the fact that the current treatment methods cannot endow paper cultural relics with other properties, such as mechanical strength and corrosion resistance, while deacidifying them and leaving a certain amount of alkali. Bacteria performance etc.
