摘要
由纤维素-壳聚糖的接枝改性物配以适量的交联剂制成一定浓度的胶液,喷涂于纸样表面,分别对处理前后的纸样进行了抗张强度、耐折度、抗干热加速老化、光泽度等测试分析,并用FT-IR和扫描电镜进行表征。结果表明,经胶液保护后,纸样保持了原有的质感、光泽、颜色,抗张强度及耐折度均有明显提高,由此证明,以纤维素-壳聚糖接枝产物为主要成分的保护胶液对纸质文物有明显的保护效果。
Using cellulose-chitosan graft product as antibiosis cellulose material for the protection of the paper based historic relics was reported in this article. The product was dissolved by organic solvent to prepare a solution with proper concentration and sprayed onto the surface of the paper. The results of tensile strength, folding endurance, gloss, dry-heat ageing tests, and FT-IR analysis, showed that the tensile strength and folding endurance increase obviously of the treated paper while it retains its original feeling, gloss, and color. It proves that the cellulose-chitosan graft product has a good protection effect on the results of paper based historic relics.
