Description

1. Technical field

[0001] The multifunctional reinforcing and protecting glue for paper-based historical documents of the invention belongs to a kind of glue for protecting paper-based historical documents. Paper historical documents include ancient books, calligraphy, calligraphy and paintings, documents, newspapers and magazines, etc. 2. Background technology

[0002] The main feature of the multifunctional reinforcement and protection glue for paper historical documents is that it can basically maintain the original color, luster, luster, texture and thickness of paper historical documents on the premise of basically maintaining the original appearance of paper historical documents. Under the premise, the pulverized part of the paper historical document is consolidated, the broken part of the fiber is connected, and the fiber is thickened, so that the paper historical document is reinforced and protected.

[0003] The protection methods of paper historical documents main...

Examples

example

[0033] Example (1) processing of paper that still has strength but has not yet been chalked:

[0034] In 60g of N-methyl-pyrrolidone solution, add 12g of FEVE fluororesin, 10g of modified chitosan, 14g of HDI crosslinking agent, and 4g of zinc oxide nanopowder in sequence, stir and place on an ultrasonic oscillator Medium treatment for about 20 minutes, after it is completely uniform, spray the glue evenly on the paper surface, or use a special brush to evenly dip it on the paper surface, the solvent evaporates in about 60 minutes, and then let it dry naturally for 24 minutes Hour.

[0035] Example (2) handles paper with a small amount of chalking that has almost no strength:

[0036] Add 14g of FEVE fluororesin, 12g of modified chitosan, 16g of HDI cross-linking agent, and 5g of zinc oxide nanopowder to the solution of 60g of N-methyl-pyrrolidone in turn, stir and place in ultrasonic vibration Treat it in the machine for about 25 minutes. After it is completely uniform, spr...
