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

preparation example Construction

[0030] The preparation method of the above-mentioned flame-retardant and sound-insulating composite curtain wall specifically includes the following steps:

[0031] S1. Mix the components of the PET / PVC flame-retardant composite layer 2 according to the weight ratio and put them in an oven at 100°C to dry for 4 hours, then add them to the internal mixer, set the temperature at 150-170°C, and banbury The time is 15-20min. After the internal mixing is completed, put it into a hot press, keep the pressure at 15MPa, and carry out hot-press molding at a temperature of 220-230°C to obtain the required PET / PVC flame-retardant composite layer 2 .

[0032] S2. Heat the PET / PVC flame-retardant composite layer 2 in step (1) to 60-70°C, keep it warm for 2 hours, and then embed it in the aluminum plate outer frame 1, and coat the PET / PVC flame-retardant composite layer with an organic adhesive. The contact surfaces of the composite layer 2 and the aluminum frame 1 are bonded and compacted....

Abstract

The invention discloses a flame-retardant and sound-insulating composite curtain wall, which relates to the field of composite wood. The composite curtain wall disclosed by the invention includes an aluminum plate outer frame, a PET / PVC flame-retardant composite layer, a titanium powder layer and a ceramic layer, and the upper end and side of the PET / PVC flame-retardant composite layer are connected to the aluminum plate outer frame through an organic adhesive. The surface is bonded, the lower end of the PET / PVC flame-retardant composite layer is sprayed with a layer of titanium powder, the titanium powder layer is thermally sprayed with a layer of ceramic layer, and the upper end of the aluminum plate outer frame is uniformly sprayed with a layer of polyurethane primer, Also spray one deck of benzophenone fluorocarbon paint on the polyurethane primer. The flame-retardant and sound-insulating composite curtain wall of the present invention has a simple structure and excellent flame-retardant and sound-insulating properties. The service life of the curtain wall saves costs.

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 ...
