樟木挥发性有机物成分分析及对中国纸质文物材料颜色的影响研究

Analysis of the Volatile Compounds of Camphorwood and Influence on the Materials Colour of Chinese Paper Cultural Relics

樟木是中国传统纸质文物在包装和展陈方面的常用材料,其挥发性有机物成分是影响文物保存环境因素之一。本文通过气相色谱-质谱联用技术对4种树龄樟木挥发性有机物进行了分析,并通过环境模拟实验舱法探讨两种不同树龄樟木对纸张载体和颜料颜色的影响。结果表明:樟木挥发性有机物成分非常复杂,不同树龄樟木成分含量存在一定的差异;随着在樟木环境中放置时间延长,颜料颜色变化有增大的趋势,特别是提高环境温度后,在樟木挥发性有机物和高温协同作用下颜料的变色被加剧。鉴于此,樟木类材料不适用于纸质文物的长期保存。

Camphorwood is a commonly used material for packaging and exhibition of traditional Chinese paper cultural relics.Its volatile components are one of the environmental factors affecting the preservation of cultural relics.In this article,the volatile organic compounds of four aged camphor trees were analyzed by gas chromatography-mass spectrometry(GC-MS).To explore the effects of different camphor trees on paper and pigment color,four environmental simulation experiment chambers were setup.The results showed that the volatile organic compounds in camphor wood are very complex,and there are certain differences in the content of camphor wood components at different ages.As the contact time with camphor wood increases,the color change of the pigment tends to increase.Specifically,after increasing the ambient temperature,the synergistic effect of camphor wood volatiles and high temperature intensifies the color change of the pigment.Camphor wood is not suitable for long-term preservation of paper cultural relics.
