Flame-retardant and sound-insulating composite curtain wall

Abstract

The invention discloses a flame-retardant and sound-insulating composite curtain wall, and relates to the field of composite wood. The composite curtain wall comprises an aluminum plate outer frame, aPET / PVC flame-retardant composite layer, a titanium powder layer and a ceramic layer. The upper end and the sides of the PET / PVC flame-retardant composite layer are bonded to the inner surface of thealuminum plate outer frame through an organic adhesive. The lower end of the PET / PVC flame-retardant composite layer is sprayed with the titanium powder layer. The ceramic layer is thermally sprayedon the titanium powder layer. A layer of polyurethane primer is evenly sprayed on the upper end of the aluminum plate outer frame. A layer of benzophenone fluorocarbon coating is sprayed on the polyurethane primer. The flame-retardant and sound-insulating composite curtain wall has a simple structure and excellent flame-retardant and sound-insulating properties. The aluminum plate outer frame is coated with the benzophenone fluorocarbon coating, so that the composite curtain wall has good weather resistance and strong UV resistance, the service life of the composite curtain wall is extended, and costs are saved.

Description

technical field [0001] The invention belongs to the technical field of composite panels, in particular to a flame-retardant and sound-insulating composite curtain wall. Background technique [0002] Curtain wall refers to the outer wall enclosure of the building. It uses various strong, light and beautiful building materials to replace the traditional masonry or window-wall construction method. It is surrounded by the periphery of the main structure to make the whole building achieve Beautiful, functional and safe exterior wall construction method. Because the curtain wall is not load-bearing, it is hung like a curtain, so it is also called "curtain wall". It is a light wall with decorative effect commonly used in modern large and high-rise buildings. At present, the traditional curtain walls at home and abroad are mainly stone curtain walls, glass curtain walls and metal curtain walls. However, these three kinds of curtain walls have great hidden dangers and shortcomings ...

Problems solved by technology

However, these three kinds of curtain walls have great hidden dangers and shortcomings due to the limitations of their own material properties: stone curtain walls are heavy, energy-consuming, and poor in fire protection; glass curtain walls have high energy consumption, serious light pollution, and poor fire resistance; metal curtain walls consume a lot of energy. , poor sound insulation, difficult to mass-produce

However, straw powder is a sound-absorbing material, which is to prevent echoes, and cannot well block the impact of external noise on the room; in addition, straw powder is a flammable substance, and the composite aluminum plate does not have a good flame-retardant effect.

Chinese invention patent CN206000060U discloses a flame-retardant and sound-insulating composite curtain wall panel, which is composed of a panel, a fireproof board, a perforated board and a substrate. Through the setting of the fireproof board and the perforated board, the composite curtain wall board has the effects of flame retardancy and sound insulation , but this structure increases the thickness of the composite curtain wall, and each component must be strictly restricted to get a better effect, and the structure of the perforated plate cannot well block the impact of external noise on the room, and the sound insulation effect is poor
