preparation example Construction

[0042] The present invention also provides a kind of preparation method of the grouting material that controls the hollowing disease of the ancient mural painting with adobe wall as the support body, comprising the following steps:

[0043] Mix all raw material components in the filler evenly for later use;

[0044] And, mix the main ingredient and the filler and stir evenly.

[0045] Preferably, the main agent and the filler are mixed at a cementitious ratio of 1:27.27-32.47, such as 1:27.30, 1:28.71, 1:29.55, 1:31.33 or 1:32.28.

[0046] It should be understood that the glue-to-cement ratio is the mass ratio of the solid content of the modified acrylic emulsion to the filler.

[0047] Preferably, before mixing the various raw material components in the filler, the red Aga soil, white Aga soil and Chengban soil are first crushed to 80-150 mesh, such as 80 mesh, 100 mesh, 120 mesh or 150 mesh, etc. Sieve and set aside.

Embodiment 1

[0050] A grouting material for curing the hollowing disease of ancient murals supported by adobe walls, comprising a main agent and a filler, the main agent is a modified acrylic emulsion, and the filler includes the following raw material components: red aga soil, white Aga soil, Chengban soil and glass beads. The preparation method of this filling material comprises the following steps:

[0051] (1) Prepare the main agent modified acrylic emulsion for later use.

[0052] (2) Fully mix the red Agha soil, white Agha soil, Chengban soil and glass microspheres according to the mass ratio of 2:2:1:1 to obtain the filler for later use.

[0053] (3) Mix the main ingredient and the filler according to the glue-cement ratio of 1:27.30 and add it into the mixer and stir evenly.

Embodiment 2

[0055] A grouting material for curing the hollowing disease of ancient murals supported by adobe walls, comprising a main agent and a filler, the main agent is a modified acrylic emulsion, and the filler includes the following raw material components: red aga soil, white Aga soil, Chengban soil and glass beads.

Abstract

The invention discloses a grouting material for curing the hollowing disease of ancient murals supported by adobe walls and a preparation method thereof. The grouting material includes a main agent and a filler, the main agent is a modified acrylic emulsion, and the filler includes the following raw material components: red argaite, white argaite, citrine and glass microspheres. The grouting material provided by the invention is non-toxic, tasteless, does not pollute the environment, and does not harm the cultural relics of the murals provided by the invention. In addition, glass beads have the advantages of light weight, low thermal conductivity, high strength, and good chemical stability; the main component of Arga soil is calcium carbonate, and the addition of Arga soil increases the compatibility of the grouting material.

Description

technical field [0001] The invention relates to the technical field of cultural relics protection, in particular to a grouting material for curing the hollowing disease of ancient murals supported by adobe walls and a preparation method thereof. Background technique [0002] The decorative and beautifying functions of murals make it an important content of environmental art. It is one of the earliest forms of painting in human history. The ancient murals that remain until now are extremely precious cultural relics. Years of natural weathering have caused the ancient murals to suffer from diseases such as carapace, hollowing, large-scale shedding, decolorization, discoloration, and crisp alkali. [0003] The murals in cave temples, monasteries, temples, etc. all over the country have hollow murals to varying degrees. Hollowing refers to the loss or weakening of the bonding performance between the ground layer of the mural and the support (wall, rock mass or others), resultin...
