Embodiment 1

[0035] Extraction and reinforcement method of menthol, coumarin and ethyl maltol composite material used in terracotta army excavation site stone armor

[0036] (1) Preparation of menthol, coumarin and ethyl maltol composite material

[0037] Weigh 50 grams of racemic menthol, 50 grams of coumarin and 50 grams of ethyl maltol after sublimation and purification, and place them in a 500 ml three-neck cup. Heat and stir in a water bath at 80 degrees to form a uniform solution system after melting. Under the condition of constant stirring, the temperature is lowered and solidified, and a composite material of menthol, coumarin and ethyl maltol with gradient melting point is obtained.

[0038] (2) Composite materials are used for the extraction and reinforcement of stone armor at the terracotta warriors and horses excavation site

[0039] 100 grams of the composite material of menthol, coumarin and ethyl maltol prepared above is melted in a water bath heating, and the melt is quickly brush...

Embodiment 2

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

[0043] The amount of composite material and the brushing method are the same as in Example 1. The difference is that the exfoliated painting usually remains on the surface of the soil block. In view of the fact that there are often cracks in the soil block, in addition to spreading gauze on the surface of the remaining painted soil block, the cracks need to be filled with shredded gauze strips, and the surroundings of the soil block should be carefully wrapped with gauze. After the composite melt has solidified, carefully lift the reserved surface of the gauze, and use a spatula to slowly shovel out the soil from the original attached layer.

[0044] With this 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 centim...

[0046] Extraction and reinforcement method of menthol, p-tert-butylcyclohexane and ethyl maltol composite material used in terracotta army excavation site stone armor

[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, and place them in a 500 ml three-neck cup. Heat and stir in a water bath at 80 degrees to form a homogeneous solution system after melting. Under the condition of constant stirring, the temperature is lowered to solidify, and a composite material of menthol, p-tert-butylcyclohexane and ethyl maltol with gradient melting point is obtained.

[0049] 100 grams of the above-prepared composite material of menthol, p-tert-butylcyclohexane and ethyl maltol was melted in a water bath heating, and the melt was quickly brushed on the stone armor covered with a layer of cotton gauze. During t...

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 relic protection, and specifically 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 historical and cultural information and have extremely high historical, artistic, scientific and technological value. In the past, a large number of cultural relics protection work was mostly carried out in archaeology and usually in laboratories. The protection of cultural relics at the excavation site has always been ignored by people. Unearthed cultural relics often have varying degrees of time and distance from the archaeological excavation site to the laboratory. In this process, due to subtle changes in the preservation environment, the...
