example (1

[0031] Example (1) the processing of the ink that does not have cracks and pulverization on the fractured surface of the main body:

[0032] Take 6g of gelatin to swell and dissolve in 20g of warm water, add 35g of butyl acetate and 2.5g of Span-80 to emulsify, so that the gelatin is evenly dispersed in the solvent, and after nitrogen deoxygenation, add butyl acrylate and acrylonitrile monomer Each 4g, modified zinc oxide nano-powder 0.3g and initiator ammonium persulfate 0.15g, grafting reaction at a certain temperature, obtain homogeneous solvent gelatin / butyl acrylate / acrylonitrile (English abbreviation is GEL / BA / AN, the same below) graft glue. Add a certain amount of ultra-fine carbon black to the repairing glue, adjust the color and viscosity, heat and stir evenly, so that the color of the repairing glue is basically the same as the ancient ink, put the broken ink on a clean platform, and pre-bond the broken ink position, prepare a simple clamping device, apply glue eve...

example (2

[0033] Example (2) to the processing of surface cracking and pulverized ink:

[0034] Take 4g of gelatin to swell and dissolve in 15g of warm water, then add 25g of butyl acetate dissolved in 2g of Span-80 emulsifier as the oil phase emulsification, so that the gelatin is evenly dispersed in the solvent, and then add acrylic acid after purging nitrogen to remove oxygen 3 g each of butyl ester and acrylonitrile monomer, 0.2 g of modified zinc oxide nanopowder and 0.1 g of initiator potassium persulfate, grafting reaction at a certain temperature to obtain a homogeneous solvent-based GEL / BA / AN graft glue. Add a certain amount of ultra-fine carbon black to the repairing glue, adjust the color and viscosity, heat and stir evenly, so that the color of the repairing glue is basically the same as the ancient ink, spray the glue evenly on the cracked and powdered surface of the ink, and place it In a certain humidity environment, then slowly dry to a stable humidity state.

example (3

[0035] Example (3) to the treatment of fracture and surface pulverization crisp solution ancient ink:

[0036] Take 10g of gelatin to swell and dissolve in 25g of warm water, add 40g of butyl acetate and 3g of Span-80 to emulsify, so that the gelatin is evenly dispersed in the solvent, and after purging nitrogen to remove oxygen, add butyl acrylate and acrylonitrile monomer 5g, 0.1g of modified zinc oxide nanopowder and 0.2g of initiator potassium persulfate, grafted at a certain temperature to obtain a homogeneous solvent-based GEL / BA / AN graft glue. Add a certain amount of ultra-fine carbon black to the repairing glue, adjust the color and viscosity, heat and stir well, so that the color of the repairing glue is basically the same as the ancient ink. First repair the pulverized layer on the surface, determine the number and amount of spraying repair glue according to the degree of pulverization and brittleness, and place it at room temperature for a certain period of time, so...

Abstract

The invention relates to an adhesive special for solvent-based ancient ink and a preparation method thereof, and belongs to an adhesive for protecting and restoring ancient ink cultural relics. The adhesive comprises the following components by weight percentage: 8 to 11 percent of gelatin, 25 to 30 percent of water, 45 to 50 percent of butyl acetate, 5 to 7 percent of acrylonitrile, 5 to 7 percent of butyl acrylate, 0.2 to 0.4 percent of modified zinc oxide nano-powder (treated), 3 to 5 percent of emulsifier (span-80), and 0.1 to 0.3 percent of initiator (ammonium persulfate or potassium persulfate).The adhesive is a repair adhesive special for the ancient ink, which is solvent-based, has good compatibility with a body material of the ancient ink, strong affinity, and no damage phenomena such as swelling, dissolution and the like, and has the characteristics of higher adhesive strength, aging resistance, mildew proofing and antibacterium and the like.

Description

1. Technical field [0001] The solvent-based special repairing adhesive for ancient ink and the preparation method thereof of the present invention belong to an adhesive for protecting and repairing ancient ink cultural relics, and are specially used for repairing ancient ink damaged by fracture, cracking, surface pulverization, and brittleness. 2. Background technology [0002] At present, there are no reports on adhesives specially used for repairing ancient inks in China, and some traditional methods or existing adhesives are usually used for repairing cracked and broken ancient inks. [0003] For example, the gelatin in the ink making is directly formulated into an aqueous solution adhesive for bonding, but a fatal flaw of this method is that because the ancient ink is a water-soluble material (mainly the main material gelatin in the ancient ink is soluble in water), in the The interface of the cracked and repaired part of the ancient ink will be swelled and dissolved by ...
