Problems solved by technology

However, the actual operability of this method is not strong at present. Although the acrylic resin used has excellent stability and weather resistance, it also has the disadvantages of becoming brittle at low temperature and softening at high temperature.
[0021] In addition, the current existing technology deacidifies and strengthens paper-based historical relics separately, which is not only cumbersome to operate, but also has a great impact on the treatment effect and efficiency.

Embodiment 1

[0042] In this embodiment, a method for preparing a paper-based historical relic deacidification and reinforcement protection material, the steps are as follows:

[0043] (1) under 60 ℃ of constant temperature water baths, in 100g organic solvent (according to weight ratio glycerol: the mixture of ethanol=1: 3), add 6g calcium bicarbonate and 0.5g starch, stir 15min with 600r / min speed, Then reduce the speed to 300r / min, add 70g deionized water while stirring, and stir for 10min to obtain a mixed solution;

[0044] (2) After the obtained mixed solution was ultrasonically oscillated for 20 minutes, 200 g of the above-mentioned organic solvent was added, and ultrasonically treated for 20 minutes, and then cooled to room temperature to obtain a uniform and translucent paper historical relic deacidification and reinforcement protection material.

Embodiment 2

[0046] In this embodiment, a method for preparing a paper-based historical relic deacidification and reinforcement protection material, the steps are as follows:

[0047] (1) Add 11g of magnesium ethylate and 0.5g of hydroxypropyl methylcellulose to 100g of ethanol in a constant temperature water bath at 70°C, stir at 700r / min for 20min, then reduce the speed to 400r / min, and add 90g deionized water was stirred for 15min to obtain a mixed solution;

[0048] (2) After the obtained mixed solution was ultrasonically oscillated for 20 minutes, 200 g of ethanol was added, and then ultrasonically treated for 25 minutes, cooled to room temperature, and a uniform, translucent paper-based historical relic deacidification and reinforcement protection material was obtained.

Embodiment 3

[0050] In this embodiment, a method for preparing a paper-based historical relic deacidification and reinforcement protection material, the steps are as follows:

[0051] (1) In 100g of organic solvent (according to weight ratio propanol: ethylene glycol = 1: 1 mixture) in 80 ℃ constant temperature water bath, add 3g of magnesium bicarbonate and 0.1g of hydroxyethyl cellulose, with 800r / Stir at min speed for 20 min, then reduce the speed to 500r / min, add 50g of deionized water while stirring, and stir for 15 min to obtain a mixed solution;

[0052] (2) After the obtained mixed solution was ultrasonically oscillated for 35 minutes, 200 g of the above-mentioned organic solvent was added, and ultrasonically treated for 10 minutes, and cooled to room temperature to obtain a uniform and translucent paper-based historical relic deacidification and reinforcement protection material.

Abstract

The invention discloses a paper historical relic deacidifying and reinforcing protective material. The paper historical relic deacidifying and reinforcing protective material consists of a solvent and an active component, wherein the active component is a compound formed by chelating a metal ion with starch or hydroxyl contained cellulose. In addition, the invention also discloses a preparation method of the paper historical relic deacidifying and reinforcing protective material. According to the protective material provided by the invention, deacidification and reinforcing treatment are combined, so that the protective material has the excellent comprehensive protective performances of safety, simplicity, convenience, durability, no membrane formation and the like, so that the paper historical relic is deacidified and reinforced once; the operation is simplified, and meanwhile, the obvious and durable reparation effect can be obtained. The preparation method is simple and is beneficial to popularization and application, the cost is low, and the use is safe, simple and convenient.

Description

technical field [0001] The invention relates to the technical field of paper material processing, in particular to a paper historical relic deacidification and reinforcement protection material and a preparation method thereof. Background technique [0002] Paper cultural relics include: ancient books, calligraphy and painting, literature, newspapers and magazines, etc. Especially ancient books, as one of the important carriers of cultural heritage and cultural diversity, after entering libraries, archives, collections, etc., how to preserve these precious paper-based historical relics for a long time, so that they Preventing or delaying natural erosion has become an urgent task for natural science workers. [0003] Due to factors such as water vapor, sulfide, oxides or acid compounds in the air, and ultraviolet rays, it will cause damage and acidification of paper historical relics, so it must be deacidified and reinforced. [0004] The deacidification methods of paper hi...
