A reinforcement and protection agent for crisp powder murals and its preparation and reinforcement method

Abstract

The invention provides a flaked and powdered mural reinforcing protective agent and a preparation and reinforcing method thereof. The agent is prepared from a reinforcing agent TB-1 prepared by dissolving 150-250 ml of ethyl orthosilicate in 1000 ml of ethyl alcohol, a reinforcing agent TB-2 prepared by dissolving 2-5 g of oxalic acid and 2-5 ml of phosphoric acid in each 1000 ml of ethyl alcohol, a reinforcing agent TB-3 prepared by 5-10 g of barium hydroxide and 2-3 g of poly(ethylene glycol) which are ground into the 100-200 nanometer scale through a ball mill in each 1000 ml of methyl alcohol, and a reinforcing agent TB-4 prepared by dissolving 3-5 g of disodium octoborate tetrahydrate in 100 ml of water according to the volume ratio of (2-5):(7-10):(7-10):(0.5-1.5). The coffin chamber flaked and powdered mural reinforcing material and the reinforcing method which are suitable for dry, semi-dry and humid environment conditions of arid regions, semi-arid regions and semi-humid regions are obtained.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, in particular to a reinforcement and protection agent for crispy powder murals and a preparation and reinforcement method thereof. Background technique [0002] As an important part of traditional Chinese murals, tomb murals are generally painted on the four walls, the top and both sides of the corridor of the tomb. Most of the murals in the tomb reflect the activities of the deceased during his lifetime, and there are also gods, myths and legends, historical stories, sun, moon, stars, and pattern decorations. Considering the principles of authenticity and integrity of cultural heritage, and because some tomb murals are difficult to remove due to the special drawing process, many important tomb murals are protected in situ. [0003] The tomb murals are affected by the environment such as changes in temperature and humidity, harmful gases in the air, and light intensity. After ...

AI Technical Summary

Problems solved by technology

However, after the test of timeliness, the organic protective reagent has passed the test of the environment, and there have been phenomena such as material aging, which has caused certain protective damage to the mural itself.

Inorganic reagents have good aging resistance, but some reinforcement reagents have poor permeability, do not form concentration gradients and strength gradients, and are easy to form hard shells on the reinforcement layer on the surface of murals, causing the reinforcement layer on the surface of murals to fall off, and some reinforcement reagents are also likely to cause surface whitening. Some damage to the paint layer on the surface of the mural
