A kind of preservation solution for paper documents

Abstract

The invention belongs to the technical field of document preservation, and relates to paper document quality keeping liquid. The paper document quality keeping liquid is prepared from the following raw materials in parts by weight: 8-12 parts of a film forming agent, 2-5 parts of a filtering agent, 5-15 parts of a curing agent, 0.5-1 part of talcum powder, 10-15 parts of an insect-resist agent and 50-60 parts of a solvent. When used, the atomized document quality keeping liquid is sprayed to a document in an atomization room by a matched paper document quality keeping processing device, thereby forming a sealed film to effectively prevent the document from deterioration, damages and writing fading, achieving an insect erosion prevention effect, realizing quality keeping preservation of the document for a long time, and particularly, preventing writings on the document from fading or adhering to one another. The raw materials of the paper document quality keeping liquid are reasonable and easy in proportioning, the manufacture cost is low, the processing process is reliable, the quality keeping liquid is application environment friendly, the use effect is good, and the quality keeping period is long.

Description

Technical field: [0001] The invention belongs to the technical field of document preservation, and relates to a paper document preservation liquid, which prolongs the preservation time of handwriting on the document by spraying the document preservation liquid on the document archives. Background technique: [0002] Paper document archives are a kind of document archives with paper as the carrier, referred to as documents, including official documents, drawings, letters, telegrams, household registrations, account books, contracts, certificates, manuscripts, diaries, notes, originals and manuscripts of family trees, etc. Paper files are easy to manage and use, but have the disadvantages of being easily damaged, unable to be reproduced, and needing to be kept secret.

[0002] Paper document archives are a kind of document archives with paper as the carrier, referred to as documents, including official documents, drawings, letters, telegrams, household registrations, account books, contracts, certificates, manuscripts, diaries, notes, originals and manuscripts of family trees, etc. Paper documents and archives are easy to manage and use, but have the disadvantages of being easily damaged, unable to be reproduced, and needing to be kept secret

Due to historical reasons, at present, important documents and documents are generally stored in paper materials, especially some highly confidential government documents are mostly archived in paper documents, which has a great impact on how to preserve paper documents. The archives put forward higher requirements; in order to keep the paper and its handwriting for a long time, in the prior art, on the one hand, natural materials with strong alkalinity such as lime and asbestos are used in papermaking, so that they can be stored in the future during the preservation process. Resist the acidic substances in the air so that the paper is not easy to age and damage; on the other hand, yellow tiller dyed paper and paint containing lead red are also used in the preservation process to prevent insect damage, and wooden boxes are made of fir and sycamore wood to prevent moisture and moisture. Oxidation, but the existing methods are complex, costly and difficult to apply on a large scale

[0003] As we all know, the storage of paper documents and archives is affected by many factors such as temperature, humidity, light, pests, dust, toxic and harmful gases, handwriting, paper quality, natural disasters, and wars. It is impossible to completely eliminate the influence of the above factors, but as long as there are suitable methods and proper preservation, the long-term and proper preservation of paper documents can still be realized; most of the existing technologies only consider moisture-proof or insect-proof when preserving documents and archives, and often do not Considering the aging, wear and decay of the paper itself, and rarely considering the oxidation, fading or smearing of the handwriting itself, so that many irreparable losses are often caused; in order to overcome some of the above shortcomings, many researchers have designed many technologies solution, such as a temperature-controlled storage device for paper archives disclosed in Chinese patent 201320649303.7, which realizes file storage by setting a temperature sensor and a control box with a built-in battery, signal converter, and data analysis processor in the file archive storage box. Appropriate regulation of the temperature in the device, thereby solving the adverse effects of temperature on file storage; Chinese patent 201420383804.X discloses an electromagnetic emission type file storage cabinet, which mainly solves the problem of paper file file storage during ocean voyages. It can automatically send out an alarm signal when a natural disaster occurs to facilitate searching; Chinese patent 201310537555.5 discloses a preparation method of an anti-insect composition for paper archives, and a technical method to overcome insect erosion and deterioration of archives by spraying the anti-insect composition; Chinese patent 201310537443 .X discloses a paper file storage device, which solves the problem of sealed storage of file files through the design of the device structure; Blurring and mutual print-through and other technical problems; therefore, discuss the design of a paper document preservation solution, which can form a sealing film on the surface of paper and handwriting after treatment. The film is effective in preventing corrosion, fire, moisture and insects. One-time processing before long-term storage of documents can achieve long-term and effective storage, which has good practical value and social benefits
