Paper file mould-proof bacteriostatic agent and preparation method thereof

Abstract

The invention belongs to the technical field of file protection, and discloses a paper file mould-proof bacteriostatic agent and a preparation method thereof. The paper file mould-proof bacteriostaticagent is prepared from the following raw materials in parts by weight: 50-88 parts of a porous carbon material, 3-5 parts of sodium citrate, 1-4 parts of herba pteridis multifidae powder, 2-4 parts of herba asari powder, 3-6 parts of pricklyash peel powder, 1-2 parts of litsea cubeba oil, 2-6 parts of chitosan and 1-3 parts of gelatin. The paper file mould-proof bacteriostatic agent of a microsphere structure is prepared through the steps of ultrasoundphonic, high- pressure homogenization, gelling, liquid nitrogen freezing and the like of the porous carbon material, the sodium citrate, the herba pteridis multifidae powder, the herba asari powder, the pricklyash peel powder, the litsea cubeba oil, the chitosan and the gelatin, the synergistic effect is achieved through raw material compounding, thus the mould-proof bacteriostatic time can be effectively prolonged, the paper file mould-proof bacteriostatic agent is good in mould-proof bacteriostatic effect, has no toxic and side effectson a human body, has no pollution to the environment and no impact on paper files, is not prone to burning, and can be used safely.

Description

technical field [0001] The invention belongs to the technical field of archives protection, and relates to a paper archives anti-mildew and bacteriostatic agent and a preparation method thereof. Background technique [0002] With the continuous enhancement of people's awareness of archives, the use of archives has become more and more popular, but archives management has the problem of "focusing on collection and ignoring protection". At present, most archives are still kept in paper form. Mold erosion has always been one of the most important problems faced in the protection of paper archives, and it is also a key factor affecting the life of paper archives. [0003] At present, in addition to strict disinfection and dust removal before the paper files are put into storage, anti-mold and insect-proof drugs should be applied during the storage period to prevent mildew and moths. Commonly used anti-mold and insect-proof drugs include mothballs, sanitary balls, musk and Some...

AI Technical Summary

Problems solved by technology

[0003] At present, in addition to strict disinfection and dust removal before storage, paper files must also be treated with anti-mold and insect-proof drugs during storage to prevent mold and moths. Commonly used anti-mold and insect-proof drugs include camphor balls, sanitary balls, musk and Some chemical fumigants, etc., although camphor balls and hygienic balls have certain effects, most of their active ingredients contain p-dichlorobenzene, which can irritate the eyes, skin, mucous membranes and upper respiratory tract, and can be absorbed by the human body. Methemoglobin is formed to cause cyanosis. Chemical fumigants such as methyl bromide and ethylene oxide are toxic to the human body and are flammable and explosive.
