Abstract

The invention discloses a reinforcing method utilizing waterlogged wood relics of nanocellulose. The reinforcing method comprises the following steps of: mixing nanocellulose with a filling agent to obtain a reinforcing agent; and performing dehydrating and desalination on the waterlogged wood relics, and adding the waterlogged wood relics into the reinforcing agent to soak, and performing drying for reinforcing. The waterlogged wood relics obtained by treatment of the reinforcing method are bright in color, are good in stability, do not easily separate out salts, and are especially free of secondary acid degradation. The reinforcing method disclosed by the invention can be used for effectively clearing and protecting the reinforcing method, the dried and reinforced wood is stabilized to a pH neutral state, acid corrosion and salt separation are effectively restrained, and mechanical strength of highly rotten wood is greatly reinforced.

Description

technical field

[0001] The invention relates to a reinforcement method for saturated wooden cultural relics, in particular to the preparation of a reinforcement based on nano-cellulose with different shapes and surface carboxyl functional groups, and for saturated wood relics with high water content, high water content of cell walls, severe degradation, and poor mechanical strength. Methods of processing water and wooden cultural relics. Background technique

[0002] The protection of wooden cultural relics is an important and difficult point in the field of archaeology. The fate of some cultural relics unearthed from offshore salvage and marine strata is still in jeopardy. When the water-saturated wooden relics are unearthed, the moisture content of the coniferous wood is 100%-500%, and the moisture content of the broad-leaved wood is as high as 200%-1000%. The structure, chemical composition, and mechanical properties of the wood are greatly damaged. . The main problems ...
