Abstract

The invention discloses a building surface composite membrane structure, preparation method and application, and belongs to the technical field of building materials. The composite membrane structure includes at least three membrane layers and flow guide components: the first membrane layer is installed on the building surface; the second membrane layer The film layer is sealed and connected with the first film layer to form a sealed space; the third film layer is sealed and connected with the second film layer to form a diversion space; the sealed space is arranged relative to the diversion space A position close to the building surface; the air guiding component is arranged in the air guiding space, and guides the gas in the air guiding space. By designing three membrane layers to form two enclosed spaces, the tension of the composite membrane structure can be increased, and in the two enclosed spaces, the air flow can be guided by the guide assembly, and the gas can be exchanged and circulated, which can reduce the deposition of dust. At the same time, the two enclosed spaces can Increase the thermal insulation and sound insulation function of the composite membrane structure.

Description

technical field

[0001] The invention relates to the technical field of building materials, in particular to a building surface composite membrane structure, preparation method and application. Background technique

[0002] The building surface usually refers to the building surface that people directly perceive through vision, and mainly has functions such as heat preservation, heat insulation, ventilation, lighting, sunshade and sound insulation. With the continuous improvement of people's aesthetic concept and quality of life requirements, the requirements for building materials are also gradually increasing. At present, commonly used materials mainly include polytetrafluoroethylene film, polyvinyl chloride film and ethylene-tetrafluoroethylene copolymer film, among which polytetrafluoroethylene film and ethylene-tetrafluoroethylene copolymer film are due to their performance Excellent and popular.

[0003] In the prior art, ethylene-tetrafluoroethylene copolymer membran...
