摘　　要：以生宣纸和7种国画颜料制备的字迹材料为研究对象,对其耐酸碱性、耐氧化性、耐干热老化、耐紫外老化等性能进行系统实验,以探讨壳聚糖(CTS)、海藻酸钠(SA)及羟乙基纤维素(HEC)制得的3种加固剂涂布对纸质文物的保护作用。结果表明,涂布3种加固剂对纸张和颜料的老化均起到一定的延缓作用,以质量分数0.9%的HEC与质量分数0.5%的明胶制得的复配液,具有最显著的固色效果,经过干热老化与紫外老化后,相比未涂布加固剂的字迹材料,此复配液涂布后的字迹材料的色差显著降低,同时可使酸化纸张pH值达7.55,更利于纸质文物的长期保存。In this study,with the raw Xuan paper and writing materials prepared from 7 kinds of Chinese painting pigments as research ob-jects,the properties of acid-alkali resistance,oxidation resistance,dry-heat aging resistance and UV aging resistance were expericed,the protective effects of chitosan,sodium alginate,and hydroxyethyl cellulose coating on paper relics were explored.The results showed that the three kinds of reinforcing agents all played a certain role in delaying the aging of paper and pigment.The compound solution prepared with 0.9%hydroxyethyl cellulose and 0.5%gelatin had the most significant color fixing effect.After dry-heat aging and UV aging,the color dif-ference was significantly reduced compared with the writing material without coating.At the same time,the pH value of the acidified paper could reach 7.55,which was more conducive to the long-term preservation of the paper relics.
