Problems solved by technology

[0010] At present, the external thermal insulation technology of building exterior walls has been widely used in my country at this stage, but the external thermal insulation of external walls in my country still has poor durability, relatively easy to peel off, short service life, cracked walls, low fire resistance and poor thermal insulation effect. Therefore, there is an urgent need to develop a high thermal insulation wall to overcome the deficiencies in the prior art

Abstract

The invention discloses a high-thermal insulation wall. The high-thermal insulation wall comprises a wall, wherein an interface layer, a thermal insulation layer and a finish coat are outwards and sequentially arranged from the outer wall of the wall; the interface layer is made of concrete anticorrosive paint; the thermal insulation layer is made of thermal insulation mortar; a protective layer is made of a steel wire net rack and protective mortar; and a resin coating with the thickness of 25-35 micrometers is sprayed onto the surface of the steel wire net rack in advance. A construction method of the high-thermal insulation wall comprises the following steps of: treating the bottom layer of the wall in advance, and sequentially applying the interface layer, the thermal insulation layerand the finish coat. Compared with the prior art, the high-thermal insulation wall disclosed by the invention has good durability, high strength, small shrinking percentage and a good flame retardanteffect, and solves the problems such as the cracking and bubbling of the wall in the use process of the thermal insulation wall.

Description

Technical field [0001] The invention belongs to the technical field of building energy saving, and specifically relates to a high-insulation wall and a construction method thereof. Background technique [0002] Building energy efficiency refers to the use of energy-saving building materials, appliances and products in the design, construction and use of buildings to improve the building’s thermal insulation and airtight performance, improve the operating efficiency of the heating system, and reduce energy Consumption. According to statistics, exterior walls are the main body of heat loss in building energy efficiency, accounting for nearly 50%, highlighting the important position of exterior wall insulation as a key technology for building energy efficiency. [0003] In recent years, in the process of continuous development of building thermal insulation technology, three major technical forms have been formed: external wall external thermal insulation, external wall internal ther...
