Damp-proof sound-absorbing building envelope with air layer

Abstract

The invention discloses a damp-proof sound-absorbing building envelope with an air layer. The damp-proof sound-absorbing building envelope is characterized by comprising an exterior trimming panel, a heat-insulating waterproof layer, an outer layer flame-retardant sound-absorbing heat-insulating material layer, a vapor blocking layer, an inner layer flame-retardant sound-absorbing heat-insulating material layer and an interior trimming panel which are all arranged in sequence from the outside to the inside of a room. The air layer which is sealed relatively is formed between the exterior trimming panel and the heat-insulating waterproof layer. By the arrangement of the air layer and the matched design of the heat-insulating waterproof layer, the inner layer flame-retardant sound-absorbing heat-insulating material layer, the outer layer flame-retardant sound-absorbing heat-insulating material layer and the vapor blocking layer, humidity accumulation in a heat-insulating material can be effectively avoided, and the problem that the durability, structural strength and heat insulation of a heat insulation system are affected due to poor moisture penetrability in the heat insulation system is solved. The damp-proof sound-absorbing building envelope is clear in hierarchical structure and is good in heat insulation, energy saving performance, moisture penetrability, damp prevention and sound absorption, and the shortcoming that the building porous material external building envelope is internally easily affected with damp, condensation and mold and is non-breathable and poor in sound absorption can be fundamentally overcome.

Description

technical field [0001] The invention belongs to the technical field of building enclosure structures, in particular to an air layer moisture-proof, seepage-proof, thermal insulation, sound-absorbing and sound-insulating enclosure structure. Background technique [0002] With the development of the national economy and the further improvement of people's living standards, the people's requirements for the comfort of the indoor environment are getting higher and higher, so building heating is becoming more and more common. Especially large public buildings (such as airport waiting room, station, expo buildings, super high-rise buildings over 200 meters, etc.) are widely used in metal sandwich permeable outer enclosure structures. When the buildings are heated, there is a difference in temperature and humidity between indoors and outdoors, so that Corresponding temperature and humidity gradients are formed inside the outer envelope. When the heat and moisture transfer process ...
