Polyphenyl plate thinly plastered external insulation system of outer wall

Abstract

The invention relates to a polyphenyl plate thinly plastered external insulation system of an outer wall, comprising a wall structure layer. The polyphenyl plate thinly plastered external insulation system of the outer wall is characterized in that the wall structure layer is sequentially provided with a heat insulation layer, a crack-resistant protection layer and a finishing coat outside the wall structure layer , wherein the insulation layer is formed by bonding slurry and flame-resistant type expansion polyphenyl plate; the crack-resistant protection layer is formed by crack-resistant mortar and glass fiber alkali-resistant grids; the finishing coat is outer wall flexible putty; tray rivets are arranged on the glass fiber alkali-resistant grids and connected with the wall structure layer; and the finishing coat is formed by crack-resistant mortar, flexible tile bonding agent and tile. The invention has the advantages of solving a the problems of cracking between the crack-resistant protection layer and the finishing coat, the stress concentration and the shrinkage distortion of the insulation layer and the crack-resistant protection layer, and the ageing resistance and durability of the crack-resistant protection layer and the finishing coat.

Description

technical field [0001] The invention relates to an external thermal insulation system of a polystyrene board thinly plastered external wall. Background technique [0002] With the in-depth implementation of the national energy-saving policy and the continuous improvement of people's requirements for the comfort of the indoor thermal environment, the external wall insulation system has been widely regarded as one of the most effective building energy-saving measures. powerful means. The wall is the main heat exchange carrier in the building, so the thermal insulation of the wall can play a pivotal role in the external enclosure structure and building energy saving. According to the actual situation of energy in our country, and giving priority to conservation, the energy work policy of technological reform and structural reform centered on conservation has been implemented for the national economy. Many new energy-saving technologies and materials have been developed and wi...
