豆浆水在中国书画修复中应用性能研究

摘要

Paper relics are vulnerable to conservation materials due to their fragility.To investigate the application of soy milk to conservation of paintings and paper,Xuan paper was used to simulate soy milk treated paper.The physical properties,degree of polymerization,surface morphology and chemical structure changes in Xuan paper were recorded.The results suggested that after soy milk treatment,there were more hydrogen bonds formed between the paper surface and soy protein,making the paper more water resistant.Treatment with soy milk resulted in a smaller change to the degree polymerization of the paper than did glue alum water.The scanning electron microscopy image shows a gel layer formed on the paper fiber surface after being treated with soy milk.This study provides information for further use of soy milk in conservation.%书画文物由于材质脆弱,容易受修复材料的影响。为探讨豆浆水在书画文物修复中的应用性能,采用宣纸为纸样通过模拟加速试验测试了豆浆水处理后纸张的物理性能、聚合度、表面形态和化学结构的变化。结果表明,豆浆水处理后,纸张纤维表面和蛋白质形成更多的氢键,可以提高纸张的抗水性能,对纸张聚合度影响低于胶矾水,扫描电镜结果表明豆浆水处理后纤维表面形成一层胶状物质。本研究为豆浆水的应用提供了依据。
