Embodiment 1

[0033] Extraction and strengthening method of p-tert-butylcyclohexanol used in stone armor of terracotta warriors and horses excavation site

[0034] Weigh 100 grams of p-tert-butylcyclohexanol, place it in a 500-milliliter glass beaker, heat and melt it in a 60-degree water bath, and quickly brush all 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 p-tert-butylcyclohexanol can penetrate into the stone armor better. 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.

[0035] With such an amount of p-tert-butylcyclohexanol, the weight of the stone armor extracted by the above method is 1.5 kg.

Embodiment 2

[0037] Extraction and reinforcement method of p-tert-butylcyclohexanol used in exhumation site of terracotta warriors and horses

[0038] The p-tert-butylcyclohexanol consumption and brushing method are the same as in Example 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 p-tert-butyl cyclohexanol 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.

[0039] Under such dosage of p-tert-butyl cyclohexanol, 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

[0041] Extraction and reinforcement method of coumarin used in the excavation site of the terracotta warriors and horses.

[0042] The dosage and method are the same as those in Example 2, except that coumarin is used for intensive extraction. With such an amount of coumarin, 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 discloses application and a method for temporarily reinforcing cultural relics in an excavation site by one type of reinforcing material. The reinforcing material is selected one or more of 4-tert-butylcyclohexanol, coumarin and ethyl maltol. The reinforcing method comprises the following steps: heating and melting or dissolving one or the mixture of more than two of 4-tert-butylcyclohexanol, coumarin and ethyl maltol into an organic solvent to obtain a reinforcing solution; covering the cultural relics to be reinforced with fiber textiles, and pouring or brushing the prepared reinforcing solution on the fiber textiles or directly brushing the reinforcing solution on the excavated cultural relics; and naturally volatilizing the organic solvent in the reinforcing solution, and cooling and condensing to temporarily reinforce the cultural relics. The reinforcing material is safe and toxin-free and has low price, and can be in direct contact with a human body; and compared with newly-developed menthol and a derivative reinforcing material thereof, the harsh environments including high heat and the like can be met, and the problems that the melting point of menthol is low, the volatilization is too fast and the like are solved.

Description

technical field [0001] The invention belongs to the technical field of protection of cultural relics on archaeological sites, and in particular relates to the application and method of temporary reinforcement of cultural relics on excavation sites by a type of reinforcing material. Background technique [0002] Cultural relics are non-renewable remains that carry rich information about human history and culture. In order to preserve it for a long time, people pay more and more attention to the protection of cultural heritage, but there are always some differences in the understanding of the principles of cultural relics protection at home and abroad, resulting in many differences in the evaluation of the protection effect and the specific practice of cultural relics protection. The phenomenon of "protective damage" has appeared in the protection work. [0003] The protection of cultural relics on the archaeological site refers to the rescue and temporary proper protection o...
