Abstract

The invention relates to a triad phase change and energy storage external thermal insulating system of an external wall and the job practice of the system. A boundary layer, an insulation layer, a crack shielding layer and a finishing coat are arranged from a basal wall to outside in sequence. The insulation layer comprises three layers, including a bonding insulation layer which is an insulation mortar layer, a stable insulation layer which is an insulation board and an active insulation layer which is a phase change and energy storage insulation mortar layer, which are bonded with each other from interior to exterior; wherein, the fine aggregate in the phase change and energy storage insulation mortar layer uses inorganic porous particle as vector, organic phase changed material is adsorbed and stored in the pore space, and the outside surface comprises the phase change and energy storage porous medium of polymer-based composite material film. The crack shielding layer comprises a crack shielding mortar with strengthened mesh inside, meanwhile, a clip is vertically penetrated into the basal wall from the outside of the strengthened mesh. The invention adopts a triad insulation structure as the structure and phase changeable energy-storage material as fixing material, which significantly improves the insulation effect of wall and is favorable for keeping stable indoor temperature and substantially saving the energy consumption of indoor air conditioner.

Description

(1) Technical field [0001] The invention relates to a building thermal insulation system and a construction method, an external thermal insulation system and a construction method of a building exterior wall. (2) Background technology [0002] With the enhancement of people's awareness of energy conservation and environmental protection, higher requirements are put forward for building energy conservation. In terms of building energy saving, it mainly focuses on the energy storage and heat insulation of building walls.
