Description

Space inhibition type paper cultural relic comprehensive protective agent and preparation method and application thereof
Technical Field
The invention relates to the field of paper cultural relic protection, in particular to a space inhibition type paper cultural relic comprehensive protective agent and a preparation method and application thereof.
Background
On one hand, the paper cultural relics such as paper archives, paper books, paper picture rolls and the like are easy to breed and invade microorganisms after being stored for a long time, because cellulase is produced in the metabolic process of the microorganisms, glycosidic bonds in paper fibers can be damaged, and the produced organic acid accelerates the degradation of the cellulose along with the secretion of the organic acid, so that the prevention and the treatment of the microorganisms become important subjects in the protection work of the paper archives; on the other hand, the paper is inevitably acidic due to the additives introduced in the papermaking process, and the acidification phenomenon becomes more and more serious along with the extension of the air exposure process, the existence of the acid can reduce the activation energy of beta-glycoside bonds, so that cellulose molecules are easy to hydrolyze, the beta-glycoside bonds are broken, the polymerization degree is reduced, hydrolyzed cellulose is generated, the strength of paper sheets is reduced, when the cellulose is completely hydrolyzed into glucose, the paper sheets are pulverized, and at the moment, the collection and use values of paper documents are lost. Thirdly, the method comprises the following steps: the paper is embrittled and deteriorated due to the fact that the paper is promoted to carry out oxidative degradation reaction on cellulose, lignin and the like in the paper in the environment where the paper cultural relics are located, such as temperature, humidity, illumination, pollutants in the air and the like; in addition, microorganisms can damage paper in a variety of ways, such as by generating heat, degrading nutrients, forming stains, lowering the pH of the paper, causing the paper to bind, and the like, which accelerate the aging of the paper. The paper cultural relics also record the history, so the paper cultural relics has important significance for protecting the paper cultural relics
The existing bacteriostasis of paper can be divided into two aspects of bacteriostasis of the paper and bacteriostasis of a storage space. At present, the chemical fumigation method is most widely applied to bacteriostasis of paper, for example, plum blossom and the like select mildewcide such as paraformaldehyde and the like, so that the paper has the characteristic of high sterilization efficiency, plum vine and the like describe the mildew removing effect of phosphine in paper, but the toxicity of chemical reagents such as paraformaldehyde, phosphine and the like can seriously harm the skin and respiratory system of archive management personnel and readers. In addition, the method for inhibiting bacteria of paper per se usually adopts a method of directly spraying a medicament on the paper, and although a certain effect is achieved, certain harm can be brought due to the fact that the medicament directly acts on the paper, so that the medicament which is not directly sprayed on the paper and is used for inhibiting bacteria of the paper by being put in the surrounding environment of the paper has important significance.
In addition, in the prior art, bacteriostasis, deacidification and aging resistance of the paper cultural relics are respectively carried out, the increase of the medicament not only causes the increase of the cost, but also causes harm to the surrounding environment, and more importantly, the harm to the paper cultural relics is increased along with the increase of the use of chemical agents.
