【摘要】：将纳米氧化镁、羟乙基纤维素、聚氧化乙烯和纳米二氧化钛复配制备具有脱酸、加固和抗菌功能的多功能复配液,并将其应用在纸质文物的脱酸和修复方面。结果表明,经过复配液处理后,纸张表面pH值从3.69提升至8.75,碱残留达到0.620 mol/kg,纸张抗张强度由421 N/m提升至546 N/m;再经热老化后,纸张表面pH值仍能达到8.21,碱残留达到0.600 mol/kg,抗张强度仍能保持在521 N/m,从而起到了持续保护的作用。复配液处理后的纸张具有一定的抑菌效果,抑菌圈直径达到28 mm。
[Abstract]:Nano-magnesium oxide, hydroxyethyl cellulose, polyvinyl oxide and nano-TiO _ 2 were mixed to prepare multifunctional compound solution with deacidification, strengthening and antibacterial functions, and it was applied to deacidification and restoration of paper cultural relics. The results showed that the pH value of the paper surface increased from 3.69 to 8.75, the alkali residue reached 0.620 mol / kg, the tensile strength of the paper increased from 42N / m to 546N / m, and after thermal aging, the pH value of the paper surface increased from 3.69 to 8.75, and the alkali residue reached 0.620 mol / kg. The pH value of the paper surface is still 8.21, the alkali residue is 0.600 mol / kg, and the tensile strength can be maintained at 521 N / m, which plays a continuous protective role. The paper treated with the compound solution had a certain bacteriostasis effect, and the diameter of the bacteriostasis circle was 28 mm.
