technical field

The invention relates to the fields of building energy saving and photoelectric buildings, in particular to a vacuum thermal insulation photovoltaic decoration integrated board and a preparation method thereof, which are applied to photoelectric curtain wall buildings requiring thermal insulation.

Background technique

Green building is the focus of the development of building science at present. Its core is to use the theory and technology of sustainable development to save resources, energy and reduce environmental pollution to the greatest extent in the whole process of building construction and operation. The zero-energy building that developed countries are advocating is to make full use of renewable energy such as solar energy to provide green, low-carbon and sustainable energy supply for buildings while realizing energy conservation and emission reduction in buildings, so as to reduce dependence on traditional fossil energy. To achieve this goal, countries around the world are vigorously developing safer and more reliable environmentally friendly and energy-saving building materials, while developing more advanced energy-producing building materials to realize the integration of building energy conservation and photovoltaic power generation, and transform building energy consumption into clean energy for buildings. .

Photovoltaic building materials and building integrated photovoltaics are cutting-edge scientific research in international building science. Traditional photovoltaic buildings are mostly photovoltaic curtain wall systems represented by photovoltaic glass. This system has been widely questioned and criticized due to exposed light pollution, poor safety, complicated installation, high price and high maintenance costs. How to build a large number of building exterior walls into safe and reliable photovoltaic curtain walls is of great significance for expanding the application range of solar photovoltaic building integration. There will be more and more high-rise and ultra-high-rise buildings in my country in the future, and all of them need to be thermally insulated. The combination and interaction of various functions such as photovoltaic power generation ensures that the entire system can safely and stably provide the required power to the building while realizing the basic building functions. Therefore, in the design and material selection of the entire system, it is necessary to fully consider the weight of the material, waterproof and moisture-proof, fire safety, convenient installation and economic rationality.

The curtain wall system has been widely used in building exterior walls, and is an indispensable technology for the decoration of commercial buildings, office buildings and other building exterior walls.

The photovoltaic glass curtain wall that has just started to be promoted mostly uses photovoltaic modules with tempered glass as the substrate, which has potential safety hazards such as heavy weight, tempered glass that is easy to burst and break, and light pollution. Secondly, the development and application of thermal insulation photovoltaic curtain wall with non-glass curtain wall structure is still a field that needs to be developed urgently.
