Description
Technical field
The present invention relates to the reinforcement means of waterlogged wooden culture relics, and in particular to based on different-shape and surface carboxyl groups official
Can the strengthening agent of nano-cellulose of group prepare, and, cell membrane moisture content high to water content it is high, degraded is serious, mechanical strength is poor
Waterlogged wooden culture relics processing method.
Background technology
The protection of wooden cultural relic is the emphasis and difficult point in archaeology field, and unearthed relics and marine bed are salvaged in some coastal waters
The destiny of unearthed relics is still precarious.When waterlogged wooden culture relics are unearthed, softwood moisture content is 100%-500%, broad-leaved
Material moisture content is then up to 200%-1000%, institutional framework, chemical composition, mechanical property of timber etc. and is all greatly broken
It is bad.The subject matter that the protection and reparation of waterlogged wooden culture relics face focuses on 1) Fe ionic catalysises makes sulfate formation sulfuric acid,
So as to cause wood chemistry to degrade, its structure is set further to degrade；2) cell membrane of waterlogged wooden culture relics is through life over the past thousands of years
Thing is degraded and chemical degradation, and oxidation is serious, it is lost mechanical strength and color and luster, it is difficult to differentiate original pattern, line quarter etc.
Information.At present, not having a kind of method of historical relic's protection can efficiently solve these problems.And after these waterlogged wooden culture relics are unearthed
If carrying out relevant treatment or treatment not in time, improper measures are gently then dry and cracked, and heavy then deformation even weathering disappears.Therefore, it is wooden
The protection of historical relic particularly waterlogged wooden culture relics has great importance with reparation.
It is domestic it is most widely used be Hubei Provincial Museum Mr. Chen Zhonghang invention, Jingzhou Cultural Relics Protection Center Wu along it is clear first
The improved compound glyoxal method of life, glyoxal is monomer, is polymerized by initiator, and wood cell wall is reinforced, right
Lumen is filled, and plays a part of dehydration setting.Compound glyoxal, is that glyoxal the inside has added polymerization inhibitor and bleeding agent,
Later stage carries out initiation polymerization by initiator, carries out dewater treatment to ancient times full sealing wax wood articles made of bamboo and simple wooden tablets or slips for writing in this way
Afterwards, substantially without mutation, the shrinkage factor of implements is less than 1%, and the requirement of late protection condition is relatively low, is easy to long-term guarantor for device shape and color
Deposit.Because the method forms chemical covalent bonds, so more difficult meet " reversible " and the requirement that can be reduced completely in historical relic's protection.

Hydrocarbon polymer, a part can enter cell membrane, and substitution combines hydroxyl on water and cell wall grape sugar chain with hydrogen bond formation knot
Close, another part then enters lumen instead of water as swelling agent, and is deposited in lumen to support cell membrane, prevents timber
Make wood shrinkage because cell membrane is collapsed in drying process.Because PEG is soluble in water, reinforcing process is reversible, therefore the method is at present
Archaeological circle common method, but macromolecular PEG moisture absorptions are serious, hold faintly acid, and small molecule PEG stability is poor, after causing treatment
Wood color is deeper, and the bigger color and luster of concentration deepens more serious, and texture is unclear, loses the natural colored of timber.Meanwhile, merely
Use PEG, it is impossible to the catalysis acid corrosion of Fe ions and marine bed salt are the problems such as separate out in the Gu timber that solves to be unearthed.
