摘　　要：纸张酸性是影响纸质文献保存寿命的重要因素,因此应对酸化严重的纸张进行脱酸处理。但部分近现代书籍中常添加为提高纸张表面强度、抗水性、平滑度、印刷适性等的施胶剂或其他疏水性填料,使得脱酸所需的浸润时间变长。为改善纸张的渗透性,需在脱酸液中引入润湿剂,因此探索脱酸过程中所加润湿剂对纸张性能的影响显得尤为必要。本实验筛选了4种润湿剂(吐温80、0P-10、OT-75和十二烷基硫酸钠(SDS))作为候选材料,针对纸张安全性参数和润湿性参数开展实验。结果表明,润湿剂OT-75既能达到理想的润湿效果,又可保护文物。Acidity of paper is a very important factor affecting the presercation life of the paper based cultured relics, so deacidification is necessary for the books printed with acid papers. Usually size agents or fillers are used in papermaking to enhance its strengths, water-proof ability, smoothness and printability, and they will prolong deacidifying solution permeating into papers. Wetting agents can improve decidify- ing solution penetration into this paper. In this thesis, the effects of wetting agents Tween 80, OP-10, OT-75 and SDS on the paper proper- ties and contact angles were investigated. The results indicated that wetting agent OT-75 had satisfactory wetting efficiency and also eusured the safety of paper based cultural relic.
