摘要:对文化用纸进行了模拟干热老化和湿热老化实验，通过评估纸张在老化过程中色差、pH值、机械性能、聚合度、结晶度等性能的变化，探究2种老化方式对文化用纸耐久性的影响。结果表明，干热老化对文化用纸的性能变化和降解过程均有较大的影响；在文化用纸老化过程中，氧化降解占主导地位，温度是影响文化用纸老化的主要因素。

Abstract:Simulated dry heat aging and wet heat aging tests were conducted on cultural paper in this study. The influence of different aging methods on the durability of cultural paper was explored by analyzing the changes of color difference， pH value， mechanical properties， the degree of polymerization and crystallization index. The results showed that the dry heat aging process had a significant impact on the change of properties and degradation process of cultural paper. Furthermore， oxidative degradation was dominant in the aging process and temperature was the main factor affecting the aging of cultural paper.
