Description
Technical field
The present invention relates to a kind of compounding cleaning agents and application thereof that the mildew on paper relics is cleaned.
Background technique
Paper relics are the carriers of Chinese culture, carry the gene of Chinese national culture origin, while witnessing China and going through
History transition have high historical value.But there is different degrees of damage in most of paper relics as time goes by, and mildew is
It is one.At present both at home and abroad using the methods of physical chemistry, although there is certain effect, oxidation is more serious, gives papery
The long-term preservation of historical relic brings adverse effect.
Summary of the invention
In order to solve problem above, the present invention provides a kind of main ingredient using biological enzyme as mildew cleaning agent, to mould
Spot cleaning effect is good, and paper relics are damaged with small paper relics mildew cleaning agent.
The technical solution adopted by the present invention is that: a kind of paper relics mildew bio-enzyme cleaning agent, by weight percentage, by 1-
10% biological enzyme, surfactant, the water surplus of 0.2-2% form.
Preferably, by weight percentage, it is made of the biological enzyme of 3-7%, the surfactant of 0.2-1%, water surplus.
Preferably, the biological enzyme is alkali protease, trypsase or papain.
Preferably, the surfactant is AEO carboxylic acid sodium (AEC), fatty alcohol polyoxyethylene ether
(AEO9) or pungent Plantacare 818 (APG), sodium n-alkylbenzenesulfonate (LAS) or α-sodium olefin sulfonate (AOS).
Preferably, the paper relics mildew bio-enzyme cleaning agent, by weight percentage, by 3% papain,
0.5% fatty alcohol polyoxyethylene ether, water surplus composition.
The beneficial effects of the present invention are: of the invention, using biological enzyme and surfactant system to paper relics mildew into
Row collaboration cleaning.Biological enzyme is a kind of protein with special catalysis, can reduce the activation energy of reaction, and enzyme has height
Imitate it is single-minded, mild, degradable, it is without secondary pollution the features such as.The present invention selects specific bio protease as mildew cleaning agent
Main ingredient, then form compound system with surfactant, filter out the biological enzyme compounding cleaning agent of optimum efficiency, it is clear
Except rate can achieve 90% or more and not damaged to papery.Biological enzyme compounding cleaning agent of the invention does not hurt mildew pattern
Evil, and there is fine elimination effect to pattern mildew, therefore can be applied to the cleaning of paper relics mildew.

The application of experimental example paper relics mildew bio-enzyme cleaning agent
(1) preparation of paper relics mildew
Potato sugar agar medium (PDA): potato cleans peeling, takes 200g to be cut into small pieces, adds the water of appropriate amount, boil
After boiling half an hour, with 8 layers of filtered through gauze, 10g agar powder and 20g glucose is added in filtrate, finally supplies 1000mL water,
Packing, sterilizing, a kind of rhyme scheme in Chinese operas serving as the prelude to a complete score for voices, spare fluid nutrient medium is identical with solid medium composition formula, is free of agar powder.
Paper relics mildew sample: late Qing Dynasty rice paper is cut into the pattern of several pieces of 6cm × 10cm sizes, is laid in after sterilizing
On culture dish, with sprayer respectively by penicillium chrysogenum (A), the spore of the different moulds of aspergillus niger (B) or fold blueness enzyme (C) is outstanding
Liquid is sprayed at rice paper surface respectively, and 10d is cultivated in incubator, during Spawn incubation is bred, sprays sterile distilled water every 12h,
Taken out after preferable bacterial plaque to be formed, gently handle surface mycelia with soft hairbrush, divide be placed in shady place dry in the shade for 24 hours, sealing
Drying box saves, and preparation contains the paper relics mildew sample of different mildews.
(2) it applies
Cleaning method: the cleaning agent of Example 1-7 preparation respectively, by paper relics mildew specimen holder in two blocks of sheet glass
Between be fixed, be immersed in paper relics mildew cleaning agent, impregnate 30min at room temperature, then removed with siphon method
Residual cleaner spontaneously dries, and observation mildew cleans situation after 16h, as a result as shown in table 1- table 3.
