Problems solved by technology

[0007] The traditional method of using cyclododecane as a reinforcing agent is to directly brush or apply cyclododecane to the surface of the object to be reinforced. The reinforcement strength is limited and it is not suitable for the extraction of large pieces of large-area cultural relics.

Embodiment 1

[0023] Embodiment 1 racemic menthol is used in the extraction and reinforcement method of the site stone armor of the terracotta warriors and horses excavation

[0024] Take by weighing 100 grams of racemic menthol, place it in a 500-milliliter glass beaker, heat and melt it in a 60-degree water bath, and quickly brush the melt with a hairbrush on the stone armor that has been covered with a layer of cotton gauze. During the brushing process, if the ambient temperature is too low, a 1000W infrared lamp can be used to irradiate the surface of the cotton gauze, so that the menthol can penetrate into the stone armor better.

[0025] After the melt has cooled, hold the bottom of the stone armor with your hands, and slowly lift the overall reinforced stone armor out of the excavation site for further restoration.

[0026] With such an amount of menthol, the weight of the stone armor extracted by the above method is 1 kg.

Embodiment 2

[0027] Example 2 Racemic menthol is used for the extraction and reinforcement method of the exhumed painted paintings on the site of terracotta warriors and horses excavation

[0028] Menthol consumption and brushing method are with embodiment 1. The difference is that the peeling paint usually remains on the surface of the soil block. In view of the fact that there are often cracks in the soil clods, in addition to laying gauze on the surface of the remaining painted soil clods, the cracks need to be filled with shredded gauze strips, and the surrounding soil clods should be carefully wrapped with gauze. After the menthol melt is solidified, carefully hold the reserved surface of the gauze, and slowly shovel out the soil block from the original attached layer with a spatula.

[0029] Under such a dosage of menthol, the maximum area of ​​the painted soil clod extracted by the above method is 60×60 square centimeters, and the thickness is 10 centimeters.

Embodiment 3

[0030] Example 3 L-menthol is used in the extraction and reinforcement method of the exhumed painted paintings at the excavation site of Terracotta Warriors and Horses

[0031] Consumption and method are with embodiment 2, and difference is to use L-menthol. Under such an amount of levomenthol, the maximum area of ​​the painted soil clod extracted by the above method is 60×40 square centimeters, and the thickness is 10 centimeters.

Abstract

The invention relates to application of menthol and derivatives thereof used as novel materials for the site temporary reinforcement of fragile cultural relics in the process of cultural relic excavation and a reinforcing method thereof. The reinforcing method comprises the following steps of: covering a fiber fabric on a cultural relic fragment to be reinforced; heating, melting or dissolving the menthol or the derivative thereof into an organic solvent; sprinkling or coating the obtained fusant (solution) on the covered fabric; and after solidifying the fusant or volatilizing the solvent in the solution, obtaining a temporary reinforced body. The obtained solid can be directly removed from the site and can not be broken or damaged. If a menthol derivative reinforcing agent needs to be removed, the reinforced body is just heated so that the reinforcing agent is volatilized. The invention is suitable for the extraction of shed colour paintings in the terracotta warriors and is also suitable for protective extraction of stone cultural relic fragments, rock paintings and wall paintings and the extraction of lacquer cultural relic fragments, wooden cultural relic fragments, paper cultural relics and cotton fibre cultural relics.

Description

technical field [0001] The invention relates to a new type of temporary reinforcement material and a reinforcement method for the excavation site of cultural relics. Such materials are menthol and its derivatives. The compound provided by the invention has the characteristics of non-toxicity, low price, good reinforcement effect on cultural relics and easy removal. Background technique [0002] When cultural relics are unearthed, there are often small pieces of cultural relics and surface shedding of cultural relics remaining in the soil. How to extract these remaining cultural relics is a difficult problem encountered by the cultural relics protection department. There are also the same problems: 1. For some precious cotton and linen cultural relics, because they have been buried underground for a long time, the cultural relics themselves have no strength, and direct extraction will often cause irreparable damage to them; 2. Some ancient warriors Because of the long buri...
