Abstract

Abstract A novel paper multifunctional protective solution was prepared by mixing berberine modified trimethoprimed carboxymethyl cellulose (TMP-DCMC-BBR), KH-791 modified nano-SiO2 (KH791-SiO2) and hydroxypropyl starch phosphate (HPDSP), and the mechanical properties, optical properties, antibacterial properties, aging resistance, acid and alkali resistance of the paper coated with the protective solution were investigated. It is shown that the paper coated with the multifunctional protective liquid showed good mechanical properties, and has little influence on optical properties of the paper. At the same time, it had good antibacterial properties, aging resistance and acid and alkali corrosion resistance, and there is no obvious change in paper appearance, no decolorization and ink diffusion, which is in line with the principle of “repairing the old as the old and keeping the original appearance”. Moreover, the compound solution has certain reversibility and can absorb a certain degree of ultraviolet rays, so as to weaken the damage of ultraviolet rays to the paper. It is an ideal multifunctional protective liquid for paper and has broad application prospects in paper protection.

TMP-DCMC-BBR/KH-791-SiO2/HPDSP多功能保护液在纸张保护中的应用

摘要将黄连素改性甲氧苄啶羧甲基纤维素（TMP-DCMC-BBR）、KH-791改性纳米SiO2（KH791-SiO2）和羟丙基淀粉磷酸酯（HPDSP）混合制备了一种新型纸用多功能防护液，并对其力学性能、光学性能、抗菌性能、耐老化性能、，研究了涂布保护液后纸张的耐酸性和耐碱性。结果表明，用多功能保护液涂布的纸张具有良好的力学性能，对纸张的光学性能影响不大。同时具有良好的抗菌性能、耐老化和耐酸碱腐蚀性能，纸张外观无明显变化，无脱色和油墨扩散，符合“修旧如旧，保持原貌”的原则。而且，该复合溶液具有一定的可逆性，可以吸收一定程度的紫外线，从而减弱紫外线对纸张的损伤。它是一种理想的多功能纸张保护液，在纸张保护方面具有广阔的应用前景。
