The mural strengthening experiment shows that the composite material can play a role in strengthening the mural within 12 hours, and the membrane formed by the AC33 is broken due to the carbonization of the nano calcium hydroxide into calcium carbonate, so that the water vapor exchange between the mural and the environment is less influenced. In conclusion, the composite material simultaneously overcomes the defects of the single AC33 and the single nano calcium hydroxide reinforced mural. In addition. The reinforcing strength is higher than that of the reinforcing strength of the two materials singly. The composite material has excellent industrial production prospect. And can be popularized to the reinforcement of other cultural relics such as stone cultural relics.
Description
Technical Field
The invention belongs to the technical field of ancient mural protection materials, and relates to an organic-inorganic composite material containing AC 33/nano calcium hydroxide and used for ancient mural reinforcement and a reinforcement method.
Background
In five thousand years, the ancestors of Youyou Huaxia created brilliant Chinese civilization. The mural is an important cultural relic for inheriting the civilization of the ancestors, and has important significance for researching the development of the civilization of the ancestors. However, as the mural is buried underground for a long time and is attacked by moisture and salt, the lime layer fails, various diseases such as shortenine, armor raising, hollowing and the like occur, and repair is urgently needed.
In order to repair mural painting in which the above various diseases occur, researchers have developed various protective materials. Generally, mural protection materials can be classified into two broad categories, organic and inorganic. Wherein AC33 and nano calcium hydroxide are representative of organic and inorganic. AC33 (component is polyacrylic resin) is widely used because of its advantages such as good adhesion, fast action, high strength of reinforcement, and small influence of formed film transparency on mural color (original relics, 2004,01, 81-86). Has become the main material for repairing mural in recent years. However, the film formed in the mural after the AC33 reinforces the mural is airtight, thereby affecting the exchange of water vapor between the mural and the outside, and causing the mural to swell and pulverize over a long time, which causes fatal damage to the mural.
The nanometer calcium hydroxide has little influence on the exchange of water vapor between murals and the outside, good compatibility, aging resistance and other advantages, and is concerned by people gradually, and different from the large-particle calcium hydroxide, the nanometer calcium hydroxide has the advantages of small particles, good permeability and the like. In 2001, nano calcium hydroxide is applied to repair diseases such as shortenine, nail polish and the like of murals (Langmuir 2001,17, 4251-. In 2006, s.sequeir et al used nano calcium hydroxide to deacidify paper Cultural relics with good results (Journal of clinical history 2006,7, 264-. Recently, nano calcium hydroxide has been systematically studied in reinforcing stone Cultural relics (Journal of clinical history 2015,18, 242-249). However, the nano calcium hydroxide for reinforcing murals has low reinforcing strength and slow action, and generally needs more than two weeks, so that the reinforcing efficiency is low.
