Light mortar inside and outside combined exterior wall heat-preserving system

Abstract

An external wall insulation system of a lightweight screed inside and outside combination is formed by smearing plaster lightweight screed and cement lightweight screed on the external wall of a building; wherein, the inner side of the external wall is coated with the plaster lightweight screed and the outer side of the external wall is coated with the cement lightweight screed, and both the plaster lightweight screed and the cement lightweight screed comprise lightweight aggregate which contains organosilicone modified expanded perlite. The external wall insulation system has the advantages that: aiming at the different requirements of the inner side and the outer side of the external wall of the building, the inner side of the external wall adopts the plaster lightweight screed and the outer side adopts the cement lightweight screed so as to form the novel insulation structure, thus exerting the function of the two insulation sand pulps and being beneficial to humidity control and fire prevention in the building; the external wall insulation system has the advantages of low coefficient of heat conductivity, excellent intensity index of each item, ensuing safe use, effectively reducing the deadweight of the building and the burden of basis load, extremely simple construction technique, stable physical property, existing no hollowing and crazing after construction, extremely low radioactivity, ensuring the inhabited environment to be healthy and safe as well as wide application scope.

Description

technical field [0001] The invention relates to a lightweight mortar for exterior walls of buildings, in particular to an exterior wall thermal insulation system with different lightweight mortars respectively arranged on the interior and exterior walls of the exterior walls of buildings. Background technique [0002] Today, when advocating the construction of a conservation-minded society, there are increasingly higher requirements for building insulation and energy conservation. Commonly used plastering materials include cement mortar, mixed mortar, etc., but ordinary cement mortar has high density and heavy weight, and is prone to cracking , Shedding and other phenomena, resulting in unsatisfactory insulation effect. In addition, the structure of cement-based materials has a low porosity, which makes it difficult to adjust the air humidity in the building, and the effect on fire prevention is also poor. Therefore, gypsum-based plastering mortar is gradually adopted by bu...

Problems solved by technology

For example, the density of rubber powder polystyrene particle insulation mortar is extremely low, and the thermal conductivity is also greatly reduced, so it has excellent insulation performance, but the compressive strength and bonding strength also decrease significantly, making construction difficult.
