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:In this study, a new method combining deacidification, strengthening and antibacterial steps of paper conservation was developed, by using the compound solution containing hydroxyethyl cellulose, polyethylene oxide, nano-micro magnesium oxide and titanium dioxide. It was observed that the pH value of paper surface increased from 3.69 to 8.75 and the alkali reserve was 0.620mol/kg, the tensile strength significantly improved. After thermal aging, the pH value still was 8.21 and the alkali reserve was 0.600 mol/kg, the tensile strength maintained a high level. After treatment, the paper had certain antibacterial performance, the diameter of inhibition zone was 28 mm．
