CN-117188200-B - Multifunctional ancient book repair atomizing agent and preparation method and application thereof

Abstract

The invention discloses a multifunctional ancient book repairing atomizing agent and a preparation method and application thereof, and belongs to the technical field of ancient book protection. The ancient book repairing atomizing agent is a mixed solution containing chitosan quaternary ammonium salt and ammonium zirconium carbonate. The method for treating ancient books by using the atomizing agent comprises the steps of cleaning the ancient books by impurities, placing the cleaned ancient books in a closed deacidification device, introducing a chitosan quaternary ammonium salt and ammonium zirconium carbonate mixed solution after atomizing treatment, spraying the ancient books, and then carrying out ventilation drying at the ambient temperature to finish the treatment. The ancient book repairing atomizing agent and the processing method have the multifunctional processing effects of deacidifying, enhancing, reinforcing, resisting bacteria, resisting aging and the like on the ancient books, the phenomena of uneven processing, yellowing, fading and the like caused by the coffee ring effect are avoided, the simplification of ancient book repairing processing is realized, the processing flow can be obviously shortened, the processing operation is reduced, the processing period is reduced, and the processing efficiency is obviously improved.

Description

Multifunctional ancient book repair atomizing agent and preparation method and application thereof Technical Field The invention belongs to the technical field of ancient book protection. More particularly, relates to a multifunctional ancient book repairing atomizing agent and a preparation method and application thereof. Background The history source of China is long, ancient books and cultural relics are numerous, its value is immeasurable. However, in the flowing process, ancient books and cultural relics are damaged to different degrees, on one hand, transportation and storage conditions are limited, and on the other hand, the ancient books and cultural relics in China are mainly used for maintaining physical properties of paper such as burst resistance and folding resistance by virtue of the stability of cellulose, so that the paper is easily subjected to natural erosion such as worm-eating, mildew, acidification and ageing along with the time. The main factors influencing the aging and deterioration of ancient books are that the hydrolysis of cellulose in paper under acidic conditions leads to the breakage of structural chains and the reduction of the polymerization degree. The stronger the acidity, the faster the ageing degree of the ancient books, the lower the usability of the paper, and the serious deterioration and embrittlement of the paper, even the breaking into paper scraps. Therefore, the protection and repair work of ancient books and cultural relics is crucial, and the problem of ancient books damage is solved by deacidifying and protecting paper, so that the strength of the paper is improved. In recent years, the research on ancient book deacidification protection is gradually increased, and certain achievements are also achieved. He et al propose a high-efficiency method for deacidifying and strengthening aged paper by in-situ quaternization, the performance of the treated aged paper is improved, the pH value is in the range of 7.5-9.0, the maximum alkali storage amount reaches 220mmol/kg, the tensile strength and folding endurance are respectively improved by 28.05% and 80%, meanwhile, the deacidification strengthening is realized only by coating and two-round atomization, the steps are relatively complex, and the effect of multifunctional ancient book protection cannot be realized by one-step treatment (carbon Polym,2019, 209:250-257). Jia et al propose a new paper manuscript protection method using chitosan nanoparticles as lewis base, which can realize deacidification and strengthening of paper by one-step treatment, and the treated paper has excellent durability in terms of pH, tensile strength, folding resistance and the like, and also shows good antibacterial performance, and although the chitosan nanoparticles undergo ball milling, a heterogeneous system of the chitosan nanoparticles also has the problems of easy sedimentation, uneven spraying and the like (Coatings, 2020, 10:1226). In addition, the multifunctional atomization deacidification agent is a research hot spot in recent years in the ancient book protection and repair field. The alkaline solution is atomized into micron-sized liquid drops by utilizing the ultrasonic atomizer, so that the deacidification agent can be fully absorbed by the paper, the paper is not wetted or deformed, the alkalinity of the deacidified paper can be improved, and the durability is improved. Qi Dan et al acted calcium propionate and sodium carbonate aqueous solution on paper by pressure atomization, in which calcium carbonate was formed in situ to achieve deacidification protection. The results show that the pH value of the treated paper is improved from 4.32 to 8.4, the tensile index and the folding endurance are respectively improved by 19 percent and 109 percent, and the treated paper also has certain mildew resistance (China paper making, 2022,41,52). Ren Junli et al invented a multifunctional ancient book repairing liquid and its treatment method (CN 109518527B), the repairing liquid is composed of alkaline mixed sol containing metal oxide nano particles and surfactant dispersed in inert solvent and alcohol-water mixed solution containing quaternary ammonium salt, and researches show that the ancient book treating liquid and its treatment method has deacidification, enhancement, antibiosis, anti-aging and other multifunctional treatment effects on ancient books. However, the two treatment methods are complex, the repair liquid is in a heterogeneous system and is atomized after soaking, and uneven ancient book treatment is easily caused by the coffee ring effect after soaking. Although the research results of the existing multifunctional deacidification agent are not few, most of ancient book deacidification treatment liquid is a heterogeneous system, so that the multifunctional ancient book repair protection cannot be realized by one-step treatment, and the coffee ring effect is easily generated due to inconsistent solvent evaporation ra
