Problems solved by technology

However, due to the sensitivity of collagen and collagen-tannin complexes to solvents and pH, traditional materials and methods for cleaning and pH adjustment have greater risks
Traditional wet / water-based cleaning treatments of leather exhibit low pH and shrinkage temperatures that may cause collagen to shrink or gel
The use of organic solvents may involve toxicity issues and the risk of dehydration or degreasing of the leather, compromising its structure and properties

Embodiment 1

[0043] 1) Put a piece of vegetable tanned leather cultural relic into a vacuum nitrogen-filled insecticidal sterilization and disinfection machine to kill insects and sterilize them. Use a brush to slowly remove the pollutants on the surface of the cultural relics, and then use a vacuum cleaner to absorb the dust remaining on the leather surface with appropriate force, so as to avoid damage to the leather or the hair on the leather.

[0044] 2) Put the leather with surface stains removed into the moisture regain box with automatic humidity control, first set the humidity at the same value as the original storage environment humidity of the fabric, and then gradually increase to 60% according to the gradient of 1.5% every half hour , In this process, the foam cotton is cut into the size and shape suitable for the bonded or bent part of the leather, the part where the leather artifact is bonded and the bent part are supported, and the leather artifact is tried to be unfolded slow...

Abstract

The invention relates to the field of cultural relics protection, and discloses a protection method for plant tanned cultural relics. The method specifically comprises the following steps: firstly, carrying out pest killing and sterilizing on plant tanned cultural relics, and removing surface pollution by a dry method; moistening leather, and trying to unfold the leather; preparing a micelle system by using sodium dodecyl sulfate, n-hexanol, distilled water, propylene carbonate and ethyl acetate, continuously carrying out stirring, and adding a calcium hydroxide-calcium lactate dispersion to prepare an oil-in-water nanostructured fluid; loading konjac glucomannan into the fluid, carrying out cutting and grinding to obtain small particles, brushing the small particles on stained positions of the plant tanned cultural relics, carrying out cleaning, adjusting the pH value, and then removing gel; and finally, unfolding the cultural relics, storing the culture relics in an acid-free box, and preserving the cultural relics in a sterile, dry, shady and cool environment, wherein the preservation environment is close to a buried environment. Chemical reagents used in the method are naturaland environmentally friendly, are low in toxicity and are harmless, and the plant tanned leather cultural relics protected by using the method cannot be damaged, and have the characteristics that thecultural relics can be reprocessed, old is repaired as old, and durable effectiveness are achieved.

Description

technical field [0001] The invention relates to the field of cultural relics protection, in particular to a method for protecting vegetable tanned leather cultural relics. Background technique [0002] Leather is a natural polymer material, the main component is collagen fibers, and the main chemical component of collagen fibers is collagen. Leather cultural relics contain a large amount of historical, cultural, and technological information, and are precious wealth for mankind. However, due to various reasons, many leather cultural relics cannot be effectively protected, which is very unfavorable for their display and preservation. [0003] In recent years, preventive protection has been paid more and more attention by cultural relics protection experts. The research on this aspect in our country has just started, and there are often problems caused by cultural relics in the process of restoration and preservation due to lack of knowledge of the protection of leather cultu...
