摘要
利用FT IR、DSC以及形态组织观察等方法,初步探讨了Kauramin(MF树脂)法渗透加固16世纪饱水古船残块(古像木)的过程与机理。结果表明,MF树脂可填充在橡木细胞组织的各层中,与其中的纤维素、木质素等形成大量氢键,高度交联,最终形成网络状整体,从而使古木件的机械性能得以改善。
FT- IR spectroscopy and differential scanning calorimetry was used in the preliminary analysis of the reinforeement mechanism of the Kuraumin method（melamine- formaldehyde resin） used on 16th century water- logged oak. The results showed that the water- soluble MF resin diffused effectively into the pores, the lumen, and the different cell walls. Abundant hydrogen bonding was produced by the interaction of the MF resin, the cellulose, the lignin, and the old wood. It was concluded that a highly combined structure had been foimed by the production of hydrogen bonding between the three - dimensional MF resin and the polymers in the oak, which improved the mechanical properties of the old water- logged objects being treated.
