Abstract

The invention provides a multifunctional paper cultural relic reinforcing protective agent, and belongs to the technical field of paper cultural relic protection. The preparation method comprises thefollowing steps: 1) mixing chitosan with water, standing and swelling the solution, and performing heating and stirring dissolution; 2) cooling the mixture, adding chitosanase, carrying out constant-temperature stirring treatment, and carrying out heating enzyme deactivation to obtain activated chitosan; 3) mixing sodium alginate with water, standing and swelling the mixture, and performing heating and stirring dissolution; 4) adding sodium periodate, and carrying out heating and stirring reaction to obtain a modified additive; 5) stirring and mixing fluororesin, activated chitosan, the modified additive, starch, polyethylene glycol, glycoprotein, carbomer, phospholipid and deionized water, dropwise adding the mixed additive solution, pollen and vitamins, and stirring and mixing all the components to obtain the multifunctional paper cultural relic reinforcing protective agent. After the multifunctional paper cultural relic reinforcing protective agent is applied and cured, a system canhave excellent mechanical properties.

Description

Technical field [0001] The invention provides a multifunctional paper cultural relics reinforcement and protection agent, which belongs to the technical field of paper cultural relics protection. Background technique [0002] The historical remains or unearthed paintings, calligraphy, scriptures and other paper cultural relics are precious historical materials that record human history, science and technology. However, with the passage of time and environmental changes, paper cultural relics have been acidified, yellowed, decayed, broken, powdery, aging, and moth-eaten to varying degrees, greatly reducing their storage life and viewing and research value, and urgently need to be reinforced and protected. Paper cultural relics are thin, soft and low-quality materials. The consequences of improper protection will be devastating and irreparable. [0003] At present, the reinforcement and protection of paper cultural relics mainly include support and mounting method, film adding metho...
