Description
Technical field
The invention belongs to chemical field, especially relate to a kind of composition and method of making the same and application that can be used for protecting paper document.
Background technology
Books, manuscript, painting and calligraphy, through folding, periodical etc., usining paper as the paper relics of carrier, is historical real record, for the propagation of human civilization, the progress of society and the development of science and technology, has brought into play irreplaceable important function.Paper relics is the important component part of Chinese history historical relic, not only having high aesthetic is worth, the abundant information such as politics, economy, military affairs, science and technology, culture and art and social life etc. that itself has also contained the creation age, by the research to all kinds of paper relics, be of value to and improve constantly the understanding of people to the Chinese elite traditional culture.No matter the value of paper relics is present or future, is all immeasurable.
Paper relics is generally organic material, the paper relics that successive dynasties are handed down from ancient times or unearthed, as time goes by, the mankind's use, dust cover, soak that hydrolysis, mould are grown, in nature air harmful substance the factor such as pollution and oxidation and cause turning to be yellow go mouldy, efflorescence brittle failure, poor rotten fragmentation, stain have one's face covered with, what have even can't stir, greatly reduce historical relic the preservation life-span and view and admire, researching value.Since paper invention, the method that the continuous exploration of people can long preservation.Why three color grade of Nanjing Museum (" East Asia paper relics protection: first East Asia paper protection scientific seminar collection of thesis "; 2008,55～62) silk screen used is made into by single-silk, sprays thermosol on silk screen; only need press with electric iron during use, make it and the paper adhesion.This silk net reinforcing technical operation is easy, material is ageing-resistant, and the paper relics protection that is applied to general value has certain effect.Although this method makes brokenly to be shielded and sustain through volume, the covering or can cause obstruction to the identification of word of silk screen, this seems particularly evident on the photograph plate.(" the archival science researchs " 1996 such as Zhang Xin Min; (4): 63～64) utilize the gamma radiation reinforcement technique to be reinforced whole book; its principle is to utilize gamma ray to cause to be attached to the high molecular polymer monomer on paper; crosslinked, polymerization; thereby play the effect of reinforcement protection; the advantage of this method is not need to use solvent and initator, and polymer monomer can be obtained better osmotic effect.China just carried out the research of this work in 1958, through radiated by gamma-ray, process, can make insect death or offspring sterile, but be applied to killing of historical relic insect, because considering the preciousness of historical relic and the characteristics that historical relic is of a great variety, material is different, should further study, at present unsuitable promotion and application, in order to avoid cause the loss that can't retrieve to historical relic.(historical relic's protection and the archaeology science such as Gong Decai; 1996; 8; (1): 29～34) introduced group and drawn the synthetic fibre vapour deposition to reinforce the method for paper, drawn the paper relics of synthetic fibre protection through group, waterproof, fungi-proofing, corrosion resistance is good; but certain variation has occurred in the texture of paper; and, due to the restriction of equipment cost, can't apply, the scope of application has very large limitation.
Above method is preserved by paper relics and positive role has been played in protection; but also exist the drawback that can't overcome; as protective material, the identification on word causes obstruction, affects the texture of paper etc.; therefore, study a kind of method of paper relics of can protecting safely and effectively and become current problem demanding prompt solution.
