Abstract

The invention relates to reinforcing liquid for paper cultural relic protection. The reinforcing liquid for the paper cultural relic protection is prepared from the following raw materials by weight percent: 30% to 75% of hexamethylene diisocyanate trimer, 0.5% to 4% of nano silica, 0.1% to 0.3% of dibutyltin dilaurate and 20.7% to 68.9% of N,N-dimethylformamide, the nano silica is dried to obtaindried nano silica; the hexamethylene diisocyanate trimer is added into the N,N-dimethylformamide, dissolved, and kept warm for 5 to 10 minutes to obtain a mixed solution; the dried nano silica is added into the mixed solution, and the dibutyltin dilaurate is added and heated to 70 DEG C. When an isocyanate group content is up to 15% to 50%, the reinforcing liquid of the invention is obtained; thereinforcing liquid for the paper cultural relic protection is scientific and reasonable in composition, rich in raw materials, easy to produce and prepare, and good in use effect. The reinforcing liquid for the paper cultural relic protection is innovation of the reinforcing liquid for the paper cultural relic protection, and has enormous economic and social benefits.

Description

technical field

[0001] The invention relates to the protection of paper cultural relics, in particular to a reinforcement solution for the protection of paper cultural relics. Background technique

[0002] Historical relics or unearthed paper relics such as paintings, calligraphy, and scriptures are precious historical materials that record human history, science and technology. However, with changes in internal and external environments, paper relics have become acidified, yellowed, decayed, broken, and broken to varying degrees. Powdery aging, moth-eaten and mildew will greatly reduce its preservation life and ornamental and research value. Therefore, paper cultural relics urgently need to be protected. Currently, the reinforcement solution B72 (an acrylic resin) used for the protection of paper cultural relics has a high Molecular weight, its poor penetration and wettability to fibers, resulting in poor penetration of resin into fibers, causing internal stress in paper, f...

Examples

Embodiment 1

[0010] Embodiment 1: A kind of reinforcing liquid that is used for the protection of paper cultural relics is made of the following raw materials by weight percentage: 40g of hexamethylene diisocyanate trimer, 0.5g of nano silicon dioxide, 0.1g of dibutyltin dilaurate g and N,N-dimethylformamide (DMF) 30g, wherein, put the nano-silica in a vacuum drying oven, dry for 10-24h, and remove the moisture to obtain dry nano-silica; Add methylene diisocyanate trimer to N,N-dimethylformamide (DMF), heat to 50°C to dissolve, keep warm for 5~10min to obtain a mixed solution; add dry nano-silica to the mixed solution , and add dibutyltin silicate in February, raise the temperature to 70°C, carry out the reaction, measure the content of isocyanate group (-NCO) every hour, when the weight content of isocyanate group (-NCO) reaches 19%, stop the reaction and depressurize The N,N-dimethylformamide (DMF) is distilled off to obtain the reinforcing solution of the present invention.

Embodiment 2

[0011] Embodiment 2: a kind of reinforcing liquid for the protection of paper cultural relics is made of the following raw materials in weight percent: 30 g of hexamethylene diisocyanate trimer, 1.0 g of nano silicon dioxide, 0.1 g of dibutyltin dilaurate g and N,N-dimethylformamide (DMF) 30g, wherein, put the nano-silica in a vacuum drying oven, dry for 10-24h, and remove the moisture to obtain dry nano-silica; Add methylene diisocyanate trimer to N,N-dimethylformamide (DMF), heat to 50°C to dissolve, keep warm for 5~10min to obtain a mixed solution; add dry nano-silica to the mixed solution , and add dibutyltin silicate in February, raise the temperature to 70°C, carry out the reaction, measure the content of isocyanate group (-NCO) every hour, when the weight content of isocyanate group (-NCO) reaches 16%, stop the reaction and depressurize The N,N-dimethylformamide (DMF) is distilled off to obtain the reinforcing solution of the present invention.

Embodiment 3

[0012] Embodiment 3: A kind of reinforcing liquid that is used for the protection of paper cultural relics is the following raw materials by weight percent: 50g of hexamethylene diisocyanate trimer, 1.5g of nano silicon dioxide, 0.1g of dibutyltin dilaurate g and N,N-dimethylformamide (DMF) 30g, wherein, put the nano-silica in a vacuum drying oven, dry for 10-24h, and remove the moisture to obtain dry nano-silica; Add methylene diisocyanate trimer to N,N-dimethylformamide (DMF), heat to 50°C to dissolve, keep warm for 5~10min to obtain a mixed solution; add dry nano-silica to the mixed solution , and add dibutyltin silicate in February, raise the temperature to 70°C, carry out the reaction, measure the content of isocyanate group (-NCO) every hour, when the weight content of isocyanate group (-NCO) reaches 27%, stop the reaction and depressurize The N,N-dimethylformamide (DMF) is distilled off to obtain the reinforcing solution of the present invention.
