摘　　要：本研究以异构十三醇聚氧乙烯醚(TO-8)作为纸质档案油渍的清洗剂,制备不同质量分数的TO-8水溶液,借助手持式超声波渗透仪对纸张油渍模拟样品进行清洗。采用白度仪、红外光谱仪、非接触式分光光度仪、扫描电子显微镜和视频光学接触角测试仪等,表征TO-8对纸质档案上油渍的清洗作用;采用万能材料试验机、柔软度仪和pH计,表征TO-8对纸张性能的影响;采用TG/DTG热分析仪,表征TO-8对纸张热稳定性的影响。结果表明:质量分数为1.5%的TO-8水溶液清洗油渍的效果最好;TO-8在清洗样品后,纸张的抗张强度下降,柔软度增加,pH维持弱碱性;TO-8清洗纸张后,纸张的热稳定性没有改变。In this study,iso-triadecanol polyoxyethylene ether(TO-8)was used as the cleaning agent for oil stains on paper archives.TO-8 aqueous solutions with different mass fractions were prepared,and simulated oil-stained paper samples were cleaned with the help of a handheld ultrasound permeameter.A whiteness meter,an infrared spectrometer,a non-contact spectrophotometer,a scanning electron microscope and a video optical contact angle tester were used to characterize the cleaning effect of TO-8 on oil stains on paper archives.A universal material testing machine,a softness meter and a pH meter were used to characterize the effect of TO-8 on paper properties.In addition,a TG/DTG thermal analyzer was used to characterize the effect of TO-8 on the thermal stability of paper.The results show that the TO-8 aqueous solution with a mass fraction of 1.5%had the best effect on cleaning oil stains.For the paper samples,after the cleaning with TO-8,the tensile strength decreased,the softness increased,the pH remained weakly alkaline,and the thermal stability did not change.
