Abstract

The invention belongs to a mortar used for the heat insulation of external walls of buildings, which consists of fibers and a plurality of functional chemical admixtures added in the organic light heat insulation mortar. The functional chemical admixtures consists essentially of hydrophobic agent taking hydrophobic effect, such as SEAL80 of organic silicon, zinc stearate, etc. cellulose ether and guar gum taking water retention and viscosity-phobic effects, polyvinyl alcohol taking thickening and foam stabling effects, re-dispensable latex powder taking water resistant and flexibility increasing effects and a little amount of air-entraining agent for lowering the volume and the density and reducing the thermal conductivity. With the common functions of the admixtures, the construction performance, the water resistant performance and the bond strength of the heat insulation mortar are improved. The invention can be used for the heat insulation of the external walls.

Description

technical field [0001] The invention belongs to a building material, in particular to a mortar used for thermal insulation of building walls. Background technique [0002] The inorganic mineral light insulation mortar currently on the market uses inorganic mineral light particles as the aggregate and cement, mineral powder, fly ash and ash calcium as the cementitious material. Due to poor performance, low bonding strength and high bulk density , high water absorption and other reasons, it can only be used for the internal insulation of the wall, but not for the external insulation of the external wall, especially the construction performance cannot meet the requirements. Contents of the invention [0003] The invention provides a kind of mortar used for thermal insulation of building walls. In the inorganic mineral light thermal insulation mortar which takes inorganic mineral light particles as aggregate and cement, mineral powder, fly ash and ash calcium as cementitious m...
