Description

Technical Field

[0001] The present application relates to the technical field of building exterior walls, and in particular to a vacuum thermal insulation structure for building exterior walls. Background Art

[0002] Building exterior wall vacuum insulation is mainly used in exterior wall insulation systems of various buildings, especially in residential, office, factory and other building scenarios that have high requirements for insulation effect. The vacuum insulation structure of this technology can significantly improve the insulation performance of the building, reduce energy consumption and improve indoor comfort.

[0003] At present, common exterior wall insulation materials mainly include polystyrene boards, mineral wool boards, etc. Although these materials have certain insulation effects, their insulation performance may be affected under extreme climatic conditions, and the insulation effect may decrease after long-term use. In addition, the existing technology often adopts methods of increasing the thickness of insulation materials or adopting multi-layer insulation structures. However, these methods not only increase material costs, but may also affect the aesthetics and overall structure of the building's exterior walls.

[0009] As a preferred embodiment, the inner cavity of the protective layer is inlaid with a reinforcing mesh, the bonding layer is a polymer adhesive, and the protective layer is a waterproof coating or a UV-resistant coating.

[0010] By adopting the above technical solution, the robustness of the protective layer can be increased to ensure that it will not be easily damaged when bent or collided by the applied force. The polymer adhesive can be used to firmly connect the adhesive layer and the protective layer, and can protect the thermal insulation structure from erosion by the external environment, thereby extending its service life.

[0013] As a preferred implementation, the reflective layer is made of aluminum foil or a silver-plated film, and the reflective layer is disposed in the middle of the vacuum insulation layer and the thermal insulation material layer.

[0014] By adopting the above technical solution, it is possible to reflect heat and reduce the transfer of heat into the room.
