Description
Technical Field
The invention relates to the technical field of cultural relic protection, in particular to a grouting material for treating hollowing diseases of ancient murals by taking stone walls as supporting bodies and a preparation method thereof
Background
The decoration and beautification functions of the murals make the murals become important contents of environmental arts, and are one of the earliest painting forms in human history, and ancient murals which are left to date are extremely precious cultural relics. The ancient murals are subjected to diseases such as armor raising, hollowing, large-area falling, decoloration, discoloration, shortness of cake and the like due to natural weathering in the year.
Mural hollowing diseases exist in different degrees in stone cave temples, temples and the like all over the country. The hollow drum means that the bonding performance between the base layer of the mural and the support (wall, rock mass or other) is lost or weakened, so that the base layer is separated from the support. Empty drums may be present between the base layer, between the base layer and the support. The hollowing generally causes the surface of the mural to crack and bulge, and the mural falls off due to the influence of the gravity of the mural.
The traditional method for treating mural hollowing diseases comprises anchor rod anchoring, uncovering, reinforcing and repairing, sticking back and the like. The anchoring is a method for carrying out rescue repair on serious hollowing diseases, and an anchor rod with a cross anchor head is used for anchoring in the past. The method can control the expansion and extension of the hollow area and prevent the mural ground layer from falling off in a large area. The anchor head of the cross is made of a metal sheet initially, so that the reinforcing strength is ensured. But because the metal anchor head is easy to rust in the air, the metal anchor head also covers the mural. Later, the transparent organic glass plate is used, the same reinforcing effect can be achieved, and the murals covered under the anchor heads of the cross can be seen. In the 60-90 s of the 20 th century, the anchor rod with the cross anchor head is adopted to anchor the large-area hollowing murals, and the anchor rod plays a good role in rescuing and protecting the murals in Dunhuang Mogao caves. However, the anchor rod of the cross anchor head has large volume, which not only affects the integrity of the picture, but also can cause damage to the mural, and in addition, the anchor rod has poor stability in loose glutenite rock mass, poor associativity with the mural ground layer and poor durability.
In addition, the whole Tibet ancient architecture is mostly soil, wood, stone structure, and the wall body that bears the weight of the mural uses the stone wall as the main. The base material of the mural is made of local aga soil (white aga soil and red aga soil), the sand content is very high, and the base made of the material is hard and brittle and becomes loose immediately when meeting water. Once the wall stick is separated from the wall body (namely hollow bulging), the wall stick is very easy to crack and break under the action of the ground stick, and the processing difficulty is very high. When the hollowing disease develops to a certain degree, the mural can fall in a large area, and the mural is seriously damaged. In the 90 s of the 20 th century, the air-bulging murals were rescued and repaired by adopting a method of taking off, reinforcing and sticking back. Because the ancient architecture fresco ground layer is hard and brittle, if the ancient architecture fresco ground layer is taken off in a split manner, the ground layer is very easy to be broken when sawing and sewing, the picture is seriously damaged, the labor and the time are wasted, and the repairing effect is not ideal. Meanwhile, after the mural is taken off, the mural needs to be reinforced, so that the mural can be prevented from being damaged due to the fact that some water-based materials cannot be used and the mural can be scattered by carelessness. Therefore, the method of removing, reinforcing and sticking back is not preferable.
