A subject of continuous discussion in the field of underwater archaeology is how to safely extract fragile waterlogged artifacts while maintaining their best condition. In this study, lacquerware with fragile wooden body was simulated and extracted, using a triple-package reinforcement technique. Using veratraldehyde as a temporary consolidant, SH-MWCNTs@PU sponge/epoxy resin composite materials as free-form reinforced layers, and double-sided self-adhesive bandages wrapped around the outer layer, the safe underwater extraction and the layer-by-layer removal of the simulated artifacts were studied. The method maximized the preservation of the artifacts’ state and information and minimized their damage during removal and transport. This method can be used as a technique for the extraction of fragile artifacts from underwater archaeological excavation sites.

在水下考古领域中不断讨论的一个主题是如何安全地提取脆弱的浸水文物，同时保持其最佳状态。在这项研究中，使用三重包装加固技术模拟并提取了具有易碎木体的漆器。使用四乙醛作为临时固结剂，SH-MWCNTs @ PU海绵/环氧树脂复合材料作为自由形式的增强层，并在外层周围包裹有双面自粘绷带，可以安全地进行水下提取并逐层研究了模拟伪像的去除。该方法最大程度地保存了人工制品的状态和信息，并最大程度地减少了它们在搬运和运输过程中的损坏。
