Problems solved by technology

[0002] The curtain wall is the outer wall enclosure of the building, not load-bearing. It is a light wall with decorative effect commonly used in modern large and high-rise buildings. It is composed of a panel and a supporting structure system. It can have a certain displacement capacity relative to the main structure or itself. A building envelope or decorative structure that has a certain deformation capacity and does not bear the role of the main structure (the external wall frame support system is also a kind of curtain wall system). In order to respond to the call for energy saving, most of the current building curtain wall materials choose good thermal insulation performance Polystyrene or polyurethane foam materials, but polystyrene or polyurethane foam materials as plastics, large-scale use will inevitably bring environmental risks, there are also related studies on the use of starch-based foam materials as thermal insulation building materials, such as SU Qiong; The research progress of the preparation method and application of [J]. Food Industry Science and Technology, 2013, 34 (20): 381-385, but starch-based foaming materials generally have poor mechanical strength and flame retardancy, which hinders its Further promotion and application
