【摘要】：目的提高纸质文物、档案的防水、防酸、抗老化等性能。方法把样品放入JRP镀膜设备中,控制真空、温度、电场、磁场等条件对化学原料进行真空聚合,在样品表面形成纳米级保护膜。通过老化前后色度值、水接触角、耐折度、拉伸强度和海水浸泡等测试,来分别评价样品的防水、防酸、抗老化、抗撕裂等性能,并通过扫描电镜对制备的纳米级厚度的聚合物保护膜进行了检测和分析。结果镀膜纸在湿热老化前后、紫外和酸雨老化前后的色差均较小。JRP镀膜后的宣纸样品正反面接触角平均值均大于90°,而未镀膜的宣纸的接触角为0°,是处于完全润湿状态。SEM照片显示镀膜后纸张纤维宏观尺寸没有变化,纤维之间的孔洞也未见堵塞。耐折度测试结果表明,镀膜处理后可略微提高纸张的纵向耐折度。纸张拉伸强度测试表明,镀膜纸张的横向拉伸强度明显高于原纸张。酸蚀实验和海水浸泡实验表明,镀膜后的纸张样品抗酸和海水腐蚀性能优于未镀膜纸张。结论镀膜对纸张的颜色没有影响,保持了其原貌,同时能一定程度地减小湿热老化和紫外老化对纸张颜色的影响。镀膜使纸张具有良好的疏水防水功能,耐折度和拉伸强度有一定的提高,具有防酸蚀和海水腐蚀的膜层保护了基材。
[Abstract]:Objective to improve the waterproof, acid-proof and anti-aging properties of paper cultural relics and archives. Methods the samples were put into JRP coating equipment to control vacuum, temperature, electric field, magnetic field and other conditions for vacuum polymerization of chemical raw materials. Nanoscale protective films were formed on the surface of the samples. The properties of the samples such as waterproofing, acid resistance, aging resistance, tear resistance and so on were evaluated by the tests of color value, water contact angle, folding resistance, tensile strength and seawater immersion before and after aging. The polymer protective film with nanoscale thickness was examined and analyzed by SEM. Results the coating paper was prepared before and after hydrothermal aging. The color difference before and after UV and acid rain aging is smaller. The average contact angle of the Xuan paper after JRP coating is more than 90 掳, while the contact angle of the uncoated Xuan paper is 0 掳, which is in a completely wetted state. SEM photos show the paper fiber after coating. There is no change in the dimensions of the dimension. The results of the folding test showed that the longitudinal folding resistance of the paper was slightly improved after coating treatment. The tensile strength test of the paper showed that, The transverse tensile strength of the coated paper was obviously higher than that of the original paper. The acid corrosion test and seawater immersion test showed that the acid resistance and seawater corrosion resistance of the coated paper was better than that of the uncoated paper. Conclusion the coating has no effect on the color of the paper. At the same time, it can reduce the influence of wet and heat aging and ultraviolet aging on the color of paper to a certain extent. The paper has good hydrophobic and waterproof function, and its folding resistance and tensile strength are improved. The base material is protected by a film with acid resistance and seawater corrosion.
