AI Technical Summary

Problems solved by technology

Traditional adhesives cure quickly, but are inconvenient to operate and cannot be diluted into thin liquids, so they are not suitable for repairing cracks on the surface of lacquerware
Organic adhesives have excellent bonding properties, but their fatal weaknesses are poor heat resistance and aging resistance, and long curing time at room temperature

Embodiment 1

[0026] For the raised and / or peeled lacquer wood lacquer painting, take the preparation of 100g of viscous adhesive as an example, which is prepared from the following raw materials:

[0027] Refined Raw Lacquer 60g

[0028] Pb 3 O 4 20g

[0029] 2% chitosan acetic acid solution 20g

[0030] The specific preparation method is as follows: stirring 0.4g chitosan and 19.6g pure acetic acid at room temperature to form a pale yellow solution, then adding 20g Pb 3 O 4 , After stirring evenly, add 60g of refined raw lacquer, and continue to stir evenly to obtain a viscous adhesive for returning and repairing the lacquer wood lacquer that has warped and / or fallen off.

Embodiment 2

[0032] For cracked lacquer wood lacquer painting, take the preparation of 100g of thin liquid adhesive as an example, which is prepared from the following raw materials:

[0033]

[0034] The specific preparation method is as follows: stirring 0.35g chitosan and 17.15g pure acetic acid at room temperature to form a pale yellow solution, and then adding 17.5g Pb 3 O 4 , 20g of acetone, add 45g of refined raw lacquer after stirring evenly, and continue to stir evenly, that is, a thin liquid adhesive used to restore the cracked lacquer wood lacquer painting.

[0035] In order to prove the beneficial effect of the present invention, the inventor has carried out a large number of laboratory research tests, and the test conditions are as follows:

[0036] 1. Scanning Electron Microscope (SEM) Analysis

[0037] The adhesives of Example 1 and Example 2 were respectively coated on the transparent film, and after it was fully cured into a film, the film was removed and placed under...

Abstract

The invention discloses an adhesive for return restoration of raw lacquer colored drawings on lacquer and wood wares. The adhesive is composed of the following components in percentage by weight: 43 to 60% of refined raw lacquer, 15 to 25% of Pb3O4, 15 to 30% of chitosan acetic acid solution with a mass percentage of 2%, and 0 to 27% of acetone. The adhesive has the advantages of high bonding strength, good thermal stability, and resistance to high temperature, corrosion, and aging. The main components of the adhesive are similar with those of historical lacquer and wood wares. The viscosity of the adhesive can be flexibly adjusted according to the actual needs. The preparation and application technology is simple. The bonding effect is excellent. The influence of the adhesive on the historical lacquer and wood wares is maximally reduced, the adhesive and the historical lacquer and wood wares are compatible, and the operation is convenient. The adhesive can be used to restore historical lacquer and wood wares having cracks, warps, and damaged drawings.

Description

technical field [0001] The invention belongs to the technical field of cultural relics protection, and in particular relates to a viscosity-adjustable lacquer woodware cracking and warping raw lacquer color painting return repair adhesive. Background technique [0002] Lacquerware is a major contribution of the Chinese nation to human civilization. The lacquer craftsmanship in my country can be traced back to the Stone Age, and then experienced the glory of the Warring States Period to the Qin and Han Dynasties, the heyday of the Song and Yuan Dynasties, and the splendor of the Ming and Qing Dynasties. The lacquer ware unearthed in our country is of different quality, including wooden, bamboo, ceramic, etc., among which wooden tires account for the vast majority. These lacquered wood wares are of great value to the study of the social economy, culture and science and technology at that time, but not many are really well protected. During the underground decay of these cult...
