Problems solved by technology

At present, more mature industrial aerated concrete products have an absolute dry density of 400~600kg/m3, and a thermal conductivity of 0.09~0.15W/(m﹐K), which cannot meet the energy saving requirements of a single material. Further energy saving requirements of more than 65%
[0004] The resulting low thermal conductivity air-e

Description

technical field [0001] The invention belongs to the technical field of building energy-saving materials. It relates to the external wall thermal insulation material used in the project, more specifically, a green and environment-friendly autoclaved lightweight aerated concrete ultra-thin board. Background technique [0002] Building energy conservation will be a key point in the development of the construction industry in the 21st century. Using new technologies to maintain and insulate buildings is the main measure for building energy conservation. The thermal insulation function of external wall insulation is the key technology for building energy conservation. This technology can effectively solve the problem of energy loss caused by the large temperature difference between indoor and outdoor in winter and summer in my country. At the same time, it can also protect the main structure and improve the service life of the building. With the continuous advancement of buildi...
