Problems solved by technology

[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 preparation method, using the document preservation solution prepared by this method to treat paper documents can form a sealing film on the surface of paper and handwriting, and the film layer has It is effective in anti-corrosion, fire prevention, moisture-proof and insect-proof, and it can be stored for a long time and with good quality by one-time treatment before long-term storage of documents, which has good practical value and social benefits

Embodiment 1

[0018] The method for preparing the paper document preservation solution involved in the present embodiment comprises the following steps:

[0019] (1) First select fresh wormwood and pepper leaves according to the weight ratio of 3:1, clean them respectively, chop them into 1-3cm fragments and put them into the extraction container, then add fresh wormwood and pepper leaves with a weight of 3 -5 times the weight percent concentration of 75-90% ethanol aqueous solution, the temperature is controlled to be 40-45 °C in a sealed state, stirred and soaked for 2-3 hours, then left to stand for 30-60 minutes, and the supernatant is used as an insect repellent for later use ;

[0020] (2) Then mix 8-12 parts of film-forming agent, 2-5 parts of filter agent, 5-15 parts of curing agent, 0.5-1 part of talcum powder and 10-15 parts of insect repellent in a ceramic container at room temperature and mix evenly , and then heat the ceramic container and materials in a water bath to 50-60°C ...

Abstract

The invention belongs to the technical field of document preservation, and relates to a preparation method of paper document quality keeping liquid. The preparation method comprises the following steps: adding wormwood and bunge pricklyash leaves into an ethanol solution, heating, and standing to obtain supernate as an insect-resist agent, putting the insect-resist agent, a film forming agent, a filtering agent, a curing agent and talcum powder in a quantitative ratio into a ceramic container, stirring and mixing uniformly at normal temperature, and heating and stirring in thermostatic waterbath for a certain period of time to obtain a document quality keeping pulp; and sealing the document quality keeping pulp, and when processing the document, adding a solvent of a corresponding weight percentage to the document quality keeping pulp, and stirring for a certain period of time under temperature controlled condition, thereby obtaining the paper document quality keeping liquid. The preparation process is mature, the processing method is simple and reliable and application environment friendly, and the paper document quality keeping liquid has a good use effect and long quality keeping period.
