The invention discloses a kind of preparation of paper relics depickling material and its application technologies.The preparation process of material is:First deacidification agent is dissolved in deionized water, certain density clear solution is made;Then water-absorbent material is immersed in above-mentioned depickling agent solution to impregnate and takes out, dries after a certain period of time.The use of depickling material:It will wait for depickling paper relics depickling material package or sandwich, it is that can reach deacidification effect to stand certain time.
Description
Technical field
Belong to historical relic's protection field, is related to preparation and its application technology of a kind of paper relics depickling material.
Background technology
Acidification is that paper relics are common and a kind of serious deterioration phenomenon of harm, it can cause the water of paper fibre element
Solution, oxidation, cause the acceleration of paper relics to damage.It is generally believed that when the pH value of paper is less than 5.6, paper relics just should
Take depickling treatment measures.Currently, the acid stripping method of paper relics has Shui Rongyefa [Zhang Jinping, Zheng Dongqing, Lu Gang etc., it is a kind of
For the multifunctional nano combined processing liquid and preparation method thereof of paper relics protection, zl201310208232.1,2014], have
Solvent Fa [Y.Wang, Y.Fang, W.Tan, et al, Preservation of aged paper using borax in
Alcohols and the supercritical carbon dioxide system, Journal of Cultural
Heritage, 2013,14 (1):16-22], Qi Xiangfa [C.J.Williams, B.G.Kelly, Method of
Deacidifying paper, US, 4051276,1977]With Deng Lizitifa [A kind of acid stripping method of paper relics, Zhang Xi
Text, Zhejiang University, CN201110187998.7]Etc. several.Aqua-solution method, which uses, has dissolved alkaline matter such as calcium bicarbonate etc.
Aqueous solution is as depickling medium.This method has both the effect of depickling and decontamination, but must be by paper relics (such as in deacidification
More album of paintings or calligraphy historical relics such as books) dismantle progress single page dip operation, and writing, dyestuff, pigment after aqueous solution soaking on paper
A degree of colour fading or dizzy dye phenomenon are will produce, paper itself can also deform after immersion, grain is wrinkled.Organic solvent method uses
The methanol for having dissolved alkaline matter such as magnesium methoxide is depickling medium.The use of organic solvent avoids paper caused by aqua-solution method
Deformation and ink marks dizzy dye phenomenon.But this method depickling is uneven, solvent methanol is toxic and its dissolution can cause organic face
Phenomena such as dissolution of material and bonding agent.Vapor phase method is deacidification agent using diethyl zinc.When depickling, the diethyl zinc of liquid is in vacuum
Gasify rapidly in equipment and neutralization reaction occurs with the acidic materials in paper.Compared to aqua-solution method and organic solvent method, gas
Phase method have deacidification effect it is ideal and on writing, pigment substantially without influence, the advantages of will not also causing paper distortion.But, gas
Phase method needs huge vacuum installations, processing cost high.Though the zinc oxide that paper surface deposits after depickling can be steady to a certain extent
Determine the pH value of paper relics, but zinc-containing substance also has the photooxidation of accelerating fibers element simultaneously.In addition, deacidification agent diethyl zinc
Inflammable and explosive, deacidification needs the parameters such as strict temperature control, and there are An Quanyinhuan [H.Cheradame, S.Ipert,
E.Rousset, Mass deacidification of paper and books I-Study limitations gas
Phase process, Restaurator, 2003,24 (4):227-229.].Plasma method is using inert gas argon and nitrogen
Deacidification agent such as calcium hydroxide are excited the hydroxide ion for generating high activity by carrier gas in high pressure plasma generating means, and
It is used for the depickling of paper.Because the plasma of high-energy density has paper fibre certain damage, therefore use this method
It needs the energy density of plasma being maintained in reasonable range.
Invention content
The present invention provides a kind of preparation method and applications technologies of paper relics depickling material.The preparation process of material
For:First deacidification agent is dissolved in deionized water, certain density clear solution is made;Then water-absorbent material is immersed into above-mentioned depickling
It impregnates to take out after a certain period of time in agent solution and dry.The use of depickling material:It will wait for that depickling paper relics depickling material wraps up
Or sandwich, handle certain time.
1, a kind of preparation of paper relics depickling material of the present invention and its application technology, it is characterised in that the system of material
It is for step:Deacidification agent is first dissolved in the clear solution that 1%-5% is made in deionized water;Then water-absorbent material is immersed above-mentioned
It takes out and is dried as depickling material after being impregnated 10-30 minutes in depickling agent solution.The use of depickling material:It will wait for depickling papery text
Object is wrapped up or is sandwiched with depickling material, and it is 15 DEG C -25 DEG C, in relative humidity 55%-65% environmental conditions at depickling to be placed in temperature
Reason 3-7 days.
2, a kind of preparation of paper relics depickling material of the present invention and its application technology, it is characterised in that deacidification agent by
