Problems solved by technology

[0003] Some thermal insulation mortars are also processed with inorganic substances, such as expanded perlite mortar. Although the physical and chemical properties of this thermal insulation mortar are more stable than those processed with organic substances, their water absorption rate is as high as 200% to 900%. %, the mortar will shrink due to water loss during the setting and hardening process. The stress caused by this shrinkage is the main reason for the hollowing, cracking, cracking and falling off of the mortar. Therefore, the thermal insulation performance will decline during use. From the perspective of heat preservation, this kind of heat preservation mortar has no practical value
[0004] Now some people use vitrified microbeads to process thermal insulation mortar, but due to technical difficulties, its thermal conductivity has been kept at around 0.07W / m.k
Therefore, the insulation performance is not good

Description

Technical field: [0001] The invention relates to a building wall thermal insulation material, in particular to thermal insulation mortar for wall thermal insulation, in particular to high-efficiency energy-saving vitrified bead thermal insulation mortar. Background technique: [0002] At present, there are many types of thermal insulation mortar for wall insulation, and most of them are made of organic matter (such as EPS thermal insulation mortar). This kind of thermal insulation mortar processed by organic matter has good thermal insulation properties. , good chemical corrosion resistance, etc., but poor workability, there are disadvantages such as low bond strength and difficult construction in actual construction, its physical and chemical properties are also unstable, and it will emit harmful gas itself, not resistant to high temperature, and it is not used when it is discarded. When it is time, it becomes a headache of white garbage. At the same time, because EPS is a...
