Problems solved by technology

However, since the essence of these adhesives all belong to water-soluble gelatin, the same disadvantages as the above-mentioned glues will occur, and gelatin is used purely as an adhesive to repair ancient ink, and its aging resistance cannot meet the requirements.
[0005] In addition, there are commonly used 502 glue (α-cyanoacrylate glue), polyurethane and epoxy resin with solvent or solvent-free organic polymer glue to bond and repair ancient ink, although the bonding strength is high, However, it will produce obvious colored adhesive sutures, which will affect the appearance of ancient ink and easily cause protective damage
[0006] Obviously, it is difficult to meet the requirements of cultural relics protection by using the above-mentioned adhesives and their methods to bond and repair ancient ink.

example (1

[0031] Example (1) Treatment of the ink without cracking and chalking 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 emulsify 2.5g of Span-80 to make the gelatin evenly dispersed in the solvent. After deoxidizing with nitrogen, add butyl acrylate and acrylonitrile monomers. Each 4g, 0.3g of modified zinc oxide nano powder and 0.15g of initiator ammonium persulfate, were grafted at a certain temperature to obtain homogeneous solvent-based gelatin / butyl acrylate / acrylonitrile (abbreviated as GEL / BA / AN, the same below) graft glue. Add a certain amount of ultra-fine carbon black to the repair glue, adjust the color and viscosity, heat and stir evenly, so that the repair glue color 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 evenly on both ends of the broken ink, l...

[0033] Example (2) Treatment of surface cracked and chalked ink:

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

[0035] Example (3) Treatment of fractured and surface crushed ancient ink:

[0036] Take 10g of gelatin to swell and dissolve in 25g of warm water, add 40g of butyl acetate, and emulsify with Span-803g, so that the gelatin is evenly dispersed in the solvent. After deoxidizing with nitrogen, add 5g each of butyl acrylate and acrylonitrile monomers. , 0.1 g of modified zinc oxide nano-powder and 0.2 g of potassium persulfate initiator are 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 repair glue, adjust the color and viscosity, heat and stir well, so that the color of the repair glue is basically the same as the ancient ink. First repair the pulverized layer on the surface, determine the frequency and dosage of spraying repair glue according to the degree of pulverization and decompression, and leave it at room temperature for a certain period of time, so that the glue layer pen...

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 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 special repair adhesive for solvent-based ancient ink and the preparation method thereof belongs to an adhesive for protecting and repairing ancient ink cultural relics, and is specially used for repairing broken, cracked, surface pulverized, cracked and other damaged ancient ink. 2. Background technology [0002] At present, there is no report on the adhesive specially used for repairing ancient ink in China. For the repair of cracked and broken ancient ink, some traditional methods are usually used, or some existing adhesives are used. [0003] For example, the gelatin in the ink making is directly formulated into an aqueous adhesive for bonding, but a fatal flaw of this method is that since the ancient ink is a water-soluble material (mainly the main material in the ancient ink is gelatin-soluble water), At the interface of the cracked repair part of the ancient ink, the gelatin aqueous solution adhesive will swell, dissolve, and even penetra...
