Embodiment 1

[0035] Extraction and strengthening methods of menthol, coumarin and ethyl maltol composite materials for stone armor at the excavation site of Terracotta Warriors and Horses

[0036] (1) Preparation of Menthol, Coumarin and Ethyl Maltol Composite Materials

[0037] Weigh respectively 50 grams of racemic menthol, 50 grams of coumarin and 50 grams of ethyl maltol after sublimation and purification, place them in a 500 ml three-necked cup, heat and stir in an 80-degree water bath, and form a homogeneous solution system after melting. The temperature is lowered and solidified under the condition of constant stirring, and the composite material of menthol, coumarin and ethyl maltol with gradient melting point is obtained.

[0038] (2) Composite materials used in the extraction and reinforcement of stone armor at the excavation site of Terracotta Warriors and Horses

[0039] Melt 100 grams of the composite material of menthol, coumarin and ethyl maltol prepared above in a water ba...

Embodiment 2

[0042] Extraction and reinforcement methods of menthol, coumarin and ethyl maltol composite materials used in the excavation site of terracotta warriors and horses

[0043] Composite material consumption and brushing method are the same as 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 composite material 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.

[0044] With such an amount of composite material, the maximum area of ​​the painted soil block extracted by the above method is 100×100 square centimeters, and the thickness is 10 cen...

Embodiment 3

[0046] Extraction and reinforcement methods of menthol, p-tert-butylcyclohexane and ethyl maltol composite materials used in the excavation site of Terracotta Warriors and Horses

[0047] (1) Preparation of menthol, p-tert-butylcyclohexane and ethyl maltol composite material

[0048] Weigh 50 grams of racemic menthol, 50 grams of p-tert-butylcyclohexane and 50 grams of ethyl maltol after sublimation and purification, put them in a 500 ml three-necked cup, heat and stir in an 80-degree water bath, and form a homogeneous solution system after melting , cooling and solidifying under the condition of constant stirring, to obtain a composite material of menthol, p-tert-butylcyclohexane and ethyl maltol with gradient melting point.

[0049] Melt 100 grams of the composite material of menthol, p-tert-butylcyclohexane and ethyl maltol prepared above in a water bath, and quickly brush the melt on the stone armor covered with a layer of cotton gauze. During the brushing process, if the...

Abstract

The invention discloses a composite material with gradient melting points, and applications thereof in reinforcing of excavation site antiques. The composition material is a mixed material with gradient melting points and controllable volatility and prepared by mixing one or more components of p-tert-butylcyclohexanol, coumarin ethyl maltol with menthol, and the application limit of the original single temporary reinforcement material can be overcome. A method of the composition material to temporarily reinforce the antiques comprises the following steps: heating and melting the composite material or dissolving the composite material into an organic solvent, to obtain a reinforcement solution; covering a fiber fabric on the to-be-reinforced antiques, sprinkling or coating the prepared reinforcement solution onto the fiber fabric, or directly coating the reinforcement solution onto the reinforcement solution; volatilizing the organic solvent in the reinforcement solution, cooling and solidifying to realize the temporary reinforcement of the antiques. The composite material has the advantages of gradient melting points and controllable volatility, retains the sublimation characteristics and is easily removed from reinforcement parts.

Description

technical field [0001] The invention belongs to the technical field of archaeological site cultural relics protection, and in particular relates to a composite material with a gradient melting point and its use for reinforcing cultural relics at an excavation site. Background technique [0002] As an ancient civilization, my country is one of the countries with the most types of cultural heritage in the world. Cultural relics carry rich human history and cultural information, and have extremely high historical, artistic, scientific and technological values. In the past, a large number of cultural relics protection work was mostly carried out in archeology and usually in the laboratory, and the protection of cultural relics at the excavation site has been neglected by people. From the archaeological excavation site to the laboratory, the unearthed cultural relics often have different degrees of intervals in terms of time and distance. In this process, due to subtle changes i...
