| Abstract:Calligraphy and painting art have a long history in China and the splendid opuses have passed down through the ages, but due to the passage of time, most of them have appeared severe acidification, rotten, broken, folded, water stained, etc. which need to be rebuilt and repaired urgently. At present the common repair method for antique calligraphy and painting is remounting. In the process of remounting, the acidification rotten paper is easy to damage when contacting water. Through several experiments, we found that the wet tear strength of Xuan paper could increase after coating ethanol solution of phosphotungstic acid, phosphoric acid (LC1) and methanol solution of barium hydroxide (LC2). The simulated acidized rotten paper sample was prepared by artificial accelerated aging, on which LC agent was coated, then papers pH, whiteness, wet tensile strength, wet tearing strength and wet bursting strength were tested. The results indicated that LC agent not only could increase the wet strength, but also could reduce acidity, prolong the life of paper, which was of great significance for antique calligraphy and painting mounting and saving for a long time. |
