Problems solved by technology

[0007] At present, the methods for the protection of ancient books at home and abroad mainly focus on deacidification, but multifunctional ancient book treatment methods are relatively rare. Most of the treatment processes are relatively complicated, and most of them are dipping treatment, which is difficult to achieve large-scale treatment.

Embodiment 1

[0039] The preparation of a deacidification enhanced treatment solution in this embodiment, the specific steps are as follows:

[0040] Add nano-MgO to H 2 In O and IPA, MgO / H with a mass concentration of 4g / L was prepared respectively 2 4 samples each of O and MgO / IPA, and then to MgO / H 2 Add 0.1wt.% (based on the quality of the compound solution) of PEI-600, PEI-1800, PEI-10000 and PEI-70000 (PEI with different molecular weights) to the O and MgO / IPA samples in turn; mechanical stirring and ultrasonic dispersion, The mechanical stirring speed is 500r / min, and the stirring time is 30min; the ultrasonic frequency is 100KHz, and the ultrasonic time is 30min, to obtain the enhanced deacidification treatment liquid.

[0041] The determination of the dispersion effect of the deacidification enhanced treatment solution obtained in this example: after the prepared deacidification enhanced treatment solution was left to stand for 0h and 6h, the transmittance (T) (wavelength range 2...

Embodiment 2

[0044] The preparation of a deacidification enhanced treatment solution in this embodiment, the specific steps are as follows:

[0045] Nano-MgO, nano-CaO and nano-TiO were respectively 2 Add it to IPA to prepare MgO / IPA with mass concentration of 4g / L, CaO / IPA with 1g / L and TiO with 1g / L respectively 2 / IPA, then add PEI-70000 of 0.1wt.% (based on the quality of the compound liquid) respectively; mechanical stirring and ultrasonic dispersion, the mechanical stirring speed is 500r / min, and the stirring time is 30min; the ultrasonic frequency is 100KHz, and the ultrasonic time is After 30 minutes, the deacidification enhanced treatment solution was obtained.

[0046] The mensuration of the dispersion effect of the deacidification enhanced treatment liquid obtained in the present embodiment: the prepared deacidified enhanced treatment liquid was left to stand for 0h, 3h, 6h, 9h, and 12h respectively and measured its transmittance (T) (wavelength Range 200nm~900nm), then take t...

Embodiment 3

[0049] The preparation of a deacidification enhanced treatment solution in this embodiment, the specific steps are as follows:

[0050] nano-MgO and nano-TiO 2 Add it to IPA at a mass ratio of 4:1 to prepare MgO / TiO with a mass concentration of 4g / L 2 / IPA compound solution 5 parts, respectively add 0.05wt.%, 0.1wt.%, 0.2wt.%, 0.5wt.% and 1.0wt.% (based on the quality of the compound solution) of PEI-70000; mechanical stirring and Ultrasonic dispersion, the mechanical stirring speed is 500r / min, the stirring time is 30min; the ultrasonic frequency is 100KHz, the ultrasonic time is 30min, and the deacidification enhanced treatment solution is obtained.

[0051] (1) Measurement of the dispersion effect of the deacidification enhancement treatment solution in this embodiment: measure the transmittance (T) (wavelength range 200nm to 900nm ), and then take the transmittance of a specific light source wavelength (λ=810nm) to calculate the transmittance change rate (D), and the cal...

Abstract

The invention belongs to the technical field of ancient book protection, and discloses a deacidification enhancement treatment solution and a method for treating aged paper. The deacidification enhancement treatment solution is composed of metal oxide nanoparticles, a PEI dispersant and a solvent. The treatment method comprises the steps: cleaning impurities on the surface of the aged paper, putting the aged paper into a vacuum drying device after constant temperature and humidity treatment, and treating; laying the pre-treated aged paper flat in an airtight box, carrying out pressurization atomization by the deacidification enhancement treatment solution, and carrying out atomization treatment; and then placing the aged paper in a fuming cupboard, air-drying, evenly and smoothly placing between wool cloth, placing the aged paper and the wool cloth in the vacuum drying device together, carrying out drying treatment, taking out, placing in a constant temperature and humidity environment, balancing water, and completing the treatment. The deacidification enhancement treatment solution and the treatment method have the multifunctional treatment effects of deacidification, enhancement,bacteriostasis and aging resistance.

Description

technical field [0001] The invention belongs to the technical field of ancient book protection, and in particular relates to a deacidification enhanced treatment liquid and a method for treating aged paper. Background technique [0002] my country has a long history and a large number of damaged ancient books and cultural relics. Ancient books and cultural relics have value attributes such as historical relics, academic materials, and artistic representation. In the process of dissemination, due to poor storage conditions or human destruction, a large number of ancient books and cultural relics will inevitably suffer from aging, damage and other damage. Therefore, the protection of ancient books and cultural relics is very important. However, the protection of ancient books is also a worldwide problem. Traditional paper deacidification enhancement methods have more or less problems, such as complicated processes, low processing efficiency, and poor processing effects, whic...
