Along with the high-speed development of the building industry in China, the urban construction process in China is continuously accelerated, and the reasonable utilization of building resources is brought to the urban construction process in China. The energy consumption of the building is a great energy consumption country and a great energy shortage country, and the energy consumption of the building becomes a great burden for the economic development of the country, so the country pays great attention to the development of the building energy-saving work. The energy-saving way of the building mainly comprises the following steps: the energy loss of the building enclosure structure is reduced; the energy consumption of the operation of the building facilities is reduced; the consumption of non-renewable energy sources is reduced as much as possible, and the use efficiency of the energy sources is improved.
The energy consumption caused by the outer wall of the building is high in proportion to the total energy consumption of the whole building, so that the good heat insulation performance of the building wall is the core for realizing energy conservation of the building. The wall body heat preservation and structure integration is realized, the service lives of the outer wall heat preservation and the building structure are guaranteed, the steps of wall body material innovation and building energy conservation are promoted, the wall body heat preservation and structure integration is not only a great innovation of the traditional building structure, but also meets the aim of promoting carbon neutralization in the current country, and meets the requirements of continuously perfecting building standardization and building industrialization, improving building production working efficiency, reducing engineering cost, improving engineering quality and realizing sustainable development.
At present, the energy-saving wall body in China mainly comprises an outer wall inner heat preservation, an outer wall outer heat preservation and a sandwich wall (sandwich wall). The internal heat preservation technology of the outer wall gradually becomes an obsolete construction form due to the unavoidable cold and hot bridge effect, crack existence and other problems. At present, the external heat insulation technology is widely applied in China, but the external heat insulation technology has serious durability problems in China, cannot guarantee the safety and performance problems in normal use and normal maintenance time, a series of serious disasters such as large-scale external heat insulation stripping, dropping, fire and the like are frequently occurred, and experts predict that a large-scale external heat insulation disaster event will exist in the next decades. At present, the problem attracts attention of government, and some cities already start to prohibit the use of external wall external heat insulation technology. Compared with the internal heat preservation and external heat preservation technologies, the sandwich wall (sandwich) wall can integrate heat preservation, bearing and decoration, is a technical product which is most applied in the composite heat preservation wallboard, and is suitable for the wall body requirements of energy conservation performance of different areas in China. However, at present, most sandwich walls adopt heat-insulating materials filled with corresponding organic or inorganic materials, the construction process is complex, the production and construction period is long, quality problems easily occur in the actual construction process, the actual experience and the existing production process are depended, and the heat-insulating and energy-saving effects cannot be guaranteed efficiently. The heat insulation layer and the structural layer are separated, so that the integration of heat insulation and structure is not really realized, and the construction cost is high.
For the outer wall of a building, besides the sufficient mechanical properties, the outer wall is required to have good heat preservation, heat insulation, sound insulation and water resistance, and the outer wall board made of a single material generally cannot meet the comprehensive requirements of the properties, especially the requirements of heat preservation and sound insulation. According to the development trend of the energy-saving exterior wall boards, the building market is expected to develop new wall materials. How to solve the technical problems is the subject faced by the invention, under the background, a composite wall material integrating the performances of heat preservation, heat insulation, fire prevention, water prevention, sound insulation, light weight, durability and the like is developed, and the composite wall material has very important practical significance and social and economic values.
