Problems solved by technology
The above external wall insulation systems have the defect of poor air permeability: the water absorption rate of polystyrene foam board or foamed polyurethane is very low, and the gas permeability is also very low. If they are used in the living room of such wall materials for a long time, " "stuffy" feeling

Abstract
The present invention discloses an outer insulation wall, it is characterized by the concrete exterior wall surface is equipped with multi-block permeability insulating material, one end of the multi-block permeability insulating material are fixed on the concrete exterior wall surface, and another end is connected with the outer template, the gap between the concrete exterior wall and outer template is injected with polyurethane foaming materials. The normal polymer insulating material has the advantages of high thermal insulation effect and low water absorption ratio, at the same time the air permeability is low, moisture is difficult to transfer, the living suitability is impacted. The present aims at the foaming polyurethane exterior wall insulating system, designs the structure which enhance the air permeability and has thermal insulation property, so the system has certain air permeability while keeps good heat insulation, can further improve the living environment.
Description
Technical field: [0001] The invention relates to the field of construction, in particular to an external thermal insulation wall and a manufacturing method thereof. Background technique: [0002] With the implementation of the national sustainable development strategy, it is imperative to establish a resource-saving society, and the requirements for energy conservation are constantly increasing. The use of thermal insulation walls in buildings is one of the main technical measures to improve the energy-saving efficiency of buildings. The thermal insulation wall is divided into internal thermal insulation system and external thermal insulation system. Relatively speaking, the external thermal insulation system has more advantages: effectively protect the main structure of the building; eliminate the phenomenon of "thermal bridge" and avoid condensation; Condensation occurs; it is beneficial to keep the room temperature stable; it does not reduce the usable area of the hous...
