Abstract

As the main carrier of art and cultural heritages, paper cultural relics are suffering from aging, oxidation, acidification, bacterial corrosion and other diseases with the passage of storage time. Therefore, it is of great significance to carry out the protection of paper cultural relics. In order to improve the bacteriostatic properties, mechanical strength and delay aging of paper, sodium carboxymethyl cellulose was modified by berberine and prepare berberylated carboxymethyl cellulose (BBR-DCMC), which is mixed with KH-791 modified nano-silica and hydroxypropyl distarch phosphate to prepare a multifunctional protective liquid integrating deacidification, reinforcement and antibacterial. The paper coated with the multifunctional protective liquid showed better antibacterial and mechanical properties, and the gloss and whiteness changed slightly. The aging test and the acid and alkali resistance test showed that the paper had certain aging resistance and acid and alkali corrosion resistance. It is an ideal protective agent for paper cultural relics and has broad application prospects in paper protection. [ABSTRACT FROM AUTHOR]
