Problems solved by technology

However, due to the compressibility and high water absorption rate of rock wool, the tensile strength is weak and it is easy to absorb a large amount of water to increase the weight of the insulation layer after it is prepared into the insulation layer structure, which causes the insulation layer to detach from the wall. become worse

Abstract

The invention relates to the field of building construction, in particular to a waterproof building exterior wall thermal insulation structure and a construction method thereof, comprising an exterior wall body, the surface of the exterior wall body is sequentially provided with a leveling layer, a first bonding layer, thermal insulation layer, second adhesive layer, waterproof layer and protective layer. The invention solves the problem that in the prior art, due to the compressibility and high water absorption rate of rock wool, after it is prepared into a thermal insulation layer structure, the tensile strength is weak and it is easy to absorb a large amount of water to increase the weight of the thermal insulation layer, thereby causing thermal insulation The layer is separated from the wall, and the thermal insulation effect becomes poor.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a waterproof building exterior wall thermal insulation structure and a construction method thereof. Background technique [0002] In recent years, fires caused by improper selection of external wall insulation materials have been shocking, causing great losses to the safety of people's lives and property. Some external wall insulation materials use foam materials, which have various effects such as caulking, bonding, sealing, heat insulation, and sound absorption. They are environmentally friendly, energy-saving, and easy-to-use materials. Poor, flammable safety is poor, so it is not the best choice. Rock wool products are internationally recognized as the main energy-saving materials in the "fifth conventional energy source" because of their excellent fireproof and thermal insulation properties. Every ton of rock wool products used for insulation in buildings can save ener...
