纸质档案绿色抑菌剂的筛选及应用研究

摘要

微生物防治是纸质档案保护的重要内容,但防治过程中对环境的污染和人体的危害一直困扰着档案保护工作者。本文选择绿色无危害抑菌剂对纸质档案进行实验,首先通过抑菌活性筛选出抑菌剂,其中接触型抑菌剂抑菌效果匹马霉素>PHMB>ε-PL>蒜氨酸,空间型抑菌剂抑菌效果香芹酚>香茅醛>2-苯乙醇;其次进行了联合抑菌实验,确定了PHMB（125mg/L）与匹马霉素（3.906mg/L）配伍的接触型抑菌剂、香芹酚（15.62mg/L）与香茅醛（31.25mg/L）配伍的空间型抑菌剂性能最好;最后对上述两组抑菌剂处理过的纸张进行安全性能检测,结果显示两种抑菌剂组合对纸张拉力无显著影响,但有显著的脱酸和抗老化效果,对处理后的纸张ΔE最大值不超过1.5。本研究为研制安全高效的纸质档案抑菌剂提供实践基础。

Abstract

Microbial prevention and control is an essential task for the protection of paper archives. However, the harmful conservation process to human body, as well as potential contamination to the environment, has always been troubling the workers. In this paper, non-harmful Eco-friendly bacteriostatic agent is selected to carry out bacteriostatic experiments on paper-based documents. Firstly, the bacteriostatic agents are selected based on antibacterial activity. Among contact-type bacteriostatic agent, their effectiveness can be ranked as pimamycin > PHMB > Epsilon-PL > Allicine; the effectiveness of spatial bacteriostatic agent can be ranked as carvol > Citronellal > 2-phenylethanol. Secondly, the test for synergistic bacteriostatic effect is carried out. PHMB (125mg/L) and Pimamycin (3.906mg/L) forms the contact-type synergistic pair that produces the optimal bacteriostatic effect. Carvol (15.62mg/L) and Citronellol (31.25mg/L) forms the spatial-type synergistic pair that has the best bacteriostatic performance. Finally, the applicability of the two identified synergistic bacteriostatis pairs were tested. Results show that both pairs of bacteriostatis agents did not induce significant changes to the tensile force of paper; significant diacidification and anti-aging effects are observed; the value of ΔE should not exceed 1.5 after the treatment. The identification, selection and validation process could provide practical basis for future development of safe and efficient bacteriostatic agent for paper.
