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 hydroxy chitosan, 14g of HDI crosslinking agent, 4g of zinc oxide nanopowder in turn, stir and place in an ultrasonic oscillator Treat 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 air for 24 hours .

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

[0036] In the solution of 60g of N-methyl-pyrrolidone, add 14g of FEVE fluororesin, 12g of hydroxy chitosan, 16g of HDI cross-linking agent, 5g of zinc oxide nanopowder in turn, and put it on the ultrasonic oscillator after stirring Medium treatment for about 25 minutes, after it is completely uniform, spray the glue on the special net,...

Abstract

The present invention relates to a multifunctional viscose solution for strengthening and protecting paper historical document. Its composition includes (by wt%) 12-15% of FEVE fluororesin, 10-14% of hydroxychitosan, 14-20% of HDI cross-linking agent, 4-8% of Zinc oxide nano powder body and 50-60% of N-methyl-pyrrolidone. Said viscose solution also has the mildew-proofing and sterilizing function.

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 Technical field [0001] The multifunctional reinforcing and protecting glue for paper-based historical documents of the invention belongs to a kind of glue for protecting paper-based historical documents. Paper historical documents include ancient books, calligraphy, calligraphy and paintings, documents, newspapers and magazines, etc. 2. Background technology [0002] The main feature of the multifunctional reinforcement and protection glue for paper historical documents is that it can basically maintain the original color, luster, luster, texture and thickness of paper historical documents on the premise of basically maintaining the original appearance of paper historical documents. Under the premise, the pulverized part of the paper historical document is consolidated, the broken part of the fiber is connected, and the fiber is thickened, so that the paper historical document is reinforced and protected. [0003] The protection methods of paper historical documents main...
