Description
Technical field
The invention belongs to paper document recovery technique field, and in particular to be aided with the LBL self-assembly papery text of vacuum infiltration
Shelves repaired item.
Background technology
Paper relics archives are the precious cultural heritages that ancestors leave us for, be Chinese history succession carrier and witness,
With important historical value, artistic value, antique value.Protecting historical relic, contributes to contemporary times and brings benefits for future centuries.However, China is existing
Ancient books situation but allows of no optimist.The paper relics ancient books archives few in number to get off are retained now generally by paper aging, acid
Document since the infringement of change, especially the Republic of China, due to so far even more few can be preserved.Therefore, for precious document
More preferable protection be that pendulum one in face of us is urgent and difficult task.
The main component of ancient books papery is cellulose, and acid is the catalyst of cellulose hydrolysis, and cellulose is in acid condition
Under be easy to occur hydrolysis.Plant cellulose is oxidized, hydrolysis produces the oxidized fibre and sulfurous acid easily crushed.It is sub-
Sulfuric acid has blanching effect, page can be made to fade, and sulfurous acid belongs to extremely unstable compound again, after oxygen in absorption air
Stable sulfuric acid can be generated.After hydrolysis, the degree of polymerization reduces cellulose, generates hydrocellulose, causes the jaundice of document paper to become
It is crisp.When cellulose hydrolysis after the degree of polymerization be down to below 200 when, document paper will serious embrittlement so that it cannot read.
Because the paper fibre element of acidifying has largely been destroyed, therefore the mechanical property of paper is largely
Decline.Therefore necessary reinforcing is carried out to paper.At present, mainly have to the reinforcement protections of paper relics support mounting method, coating method,
Silk net reinforcing method and glue method for strengthening etc..The above method is " curing the symptoms, not the disease ", it is impossible to which angle chemically really improves paper
The mechanical property opened.Moreover, the method that paper is reinforced wastes time and energy, efficiency is very low.LBL self-assembly can be in substantially any table
Face forms the controllable ultrathin membrane of thickness, is a kind of film technique widely used.Formed in order that obtaining in paper surface to be repaired
Relatively stable film, strengthen the mechanical property of paper, membrane material need to be reached into as far as possible on the basis of paper quality is not influenceed
Expect the infiltration in paper surface.
