Holographic copying painting base and production method thereof

Abstract

The invention provides a holographic copying painting base and a production method thereof. The holographic copying painting base comprises a base substrate layer, a bottom glue layer, at least one layer of rock sand soil gluing layer and a cover cementing layer; the bottom glue layer covers the base substrate layer; the rock sand soil gluing layer is glued on the bottom glue layer; the cover cementing layer is glued on the rock sand soil gluing layer. The base is not constrained by the material, and the thickness of the base layer can be added according to requirements; a soft material can realize curling, the durability is extremely high, and portability is achieved; the installation method is simple and fast, and is not limited by conditions, in particular, the curved surface installation can be realized; the holographic copying painting base can also undergo overlay treatment of other auxiliary processes, so that properties of the base are added, and for example, the holographic copying painting base further has the functions of being waterproof, fireproof, antioxidant, corrosion-resistant and anti-ultraviolet and other functions and can be used indoors and outdoors; in addition, the holographic copying painting base is not limited by painting materials, and by using different blending agents, various painting materials can be applied for artistic expression.

Description

technical field [0001] The invention relates to a holographic copying painting base and a manufacturing method thereof, belonging to the technical field of mural copying. Background technique [0002] Existing copy bases of ancient murals mainly include mud bases and paper bases. Among them, the disadvantage of mud bases is that they are fragile. Large and heavy, difficult to move and move, limited conditions for installation. [0003] Aiming at the mud-skin base in the copying base of the existing ancient murals, the aviation aluminum plate is used as the lining board, and then cement is glued on the lining board, which is treated to a texture effect similar to that of the original ancient murals, and the surface is copied. The thickness of the clay layer is generally about 1 cm. After gluing, it is hard. Its properties are relatively brittle and easy to break. The size of the mud plate is limited. If the volume is too large, the weight will also increase significantly, an...

AI Technical Summary

Problems solved by technology

First of all, the thermal expansion and contraction ratios of the two materials of aviation aluminum plate and cement are different, which makes the two parts easy to fall off or causes the surface mud skin to crack and fall off.

Secondly, the material properties of the mud skin itself are soft and easy to deteriorate; after gluing, the internal air cannot circulate, which reduces its durability, and the temperature difference between cold and hot can cause the surface to break or powder

Finally, during the transportation process, because of its heavy weight, vibrations and bumps will cause damage to varying degrees, which will greatly increase the transportation cost

Due to the limitation of the mud skin material itself, it is impossible to make large-format panels, and it needs to be spliced ​​with several small panels, which greatly increases the installation cost. In addition, there will be hidden dangers in the joint gaps between small panels; The requirements are stricter and the cost will increase; and it cannot be displayed outdoors

[0005] Aiming at the paper base in the copy base of ancient murals, its disadvantage is that it lacks texture and touch, is too flat, has poor visual effect, is difficult to preserve, is easily damaged by diseases, insect pests and ultraviolet rays, is afraid of tides and water, and is easy to be damaged and faded. , afraid of fire, and if the picture is complicated, it needs to pile up paint, and it will also cause brittleness and easy damage.
