[0002] An air film building refers to a building structure system that uses special building film materials as the outer shell and is equipped with a set of intelligent mechanical and electrical equipment to provide positive pressure air inside the air film building to support the main body of the building. In scenarios such as stadiums, warehouses, industrial factories, cold storages, etc., air films are often used as the building outer shell and are equipped with a set of intelligent mechanical and electrical equipment to provide positive pressure in the building space inside the air film to support the main body of the building. Air film buildings are mostly applied to scenarios such as stadiums, warehouses, industrial factories, cold storages, ski resorts, etc. When an air film building is applied to ultra-low temperature environments such as cold storages and ski resorts, the temperature difference between the inside and outside of the air film building is extremely large, and higher requirements are placed on the heat insulation and heat preservation performance of the air film. Therefore, a heat insulation and heat preservation device needs to be set up;
[0003] In the prior art, the heat insulation and heat preservation treatment method is to fill materials such as heat preservation cotton between two air film layers to achieve the heat preservation effect. However, this method of filling heat preservation materials has a simple structure, and the heat preservation effect of its heat preservation materials is poor, with defects. Content of the Utility Model
[0004] The purpose of the utility model is to provide an air film building heat insulation and heat preservation device to solve the problems put forward in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: an air film building heat insulation and heat preservation device, including a base, an air film building body and a composite heat preservation layer. The air film building body is fixedly connected to the top of the base. The composite heat preservation layer is arranged on the outside of the air film building body. The composite heat preservation layer is fixedly connected to the air film building body through an adhesive layer. The composite heat preservation layer includes a first heat preservation layer. One side of the first heat preservation layer is fixedly connected with a strengthening layer. One side of the strengthening layer is fixedly connected with a second heat preservation layer. One side of the second heat preservation layer is fixedly connected with a waterproof layer.
[0006] Preferably, the adhesive layer is an alkali-resistant glue layer.
[0007] Preferably, the first heat preservation layer is a silica aerogel layer.
[0008] Preferably, the strengthening layer is a fiberglass mesh cloth layer.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] For this air film building heat insulation and preservation device, the air film building body is installed and supported through the base, and the composite heat preservation layer is installed on the outer side of the air film building body through the bonding layer, thereby achieving the heat insulation and preservation effect on the air film building body. The bonding layer uses an alkali-resistant adhesive layer that can resist the corrosion of alkaline media. The composite heat preservation layer includes a first heat preservation layer formed by a silica aerogel layer, which has an extremely low thermal conductivity, can effectively reduce the heat conduction, provide good heat preservation effect, and the reinforcing layer is a fiberglass mesh cloth layer with good flexibility and tensile resistance. The second heat preservation layer is a rock wool heat preservation board layer with a large number of tiny air layers inside, so it has excellent heat preservation performance, is non-combustible, and has a high fire resistance limit. The outermost waterproof layer is a PVC waterproof coiled material layer, which has good waterproof performance and can effectively prevent water penetration. The utility model forms a composite heat preservation layer through the combined setting of multiple layers and fixes it on the outer side of the air film building, which can achieve a good heat insulation and preservation effect.
