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 wall thermal insulation material for buildings, in particular to thermal insulation mortar for wall thermal insulation, in particular to high-efficiency energy-saving vitrified microbead thermal insulation mortar. Background technique: [0002] At present, there are many types of thermal insulation mortars for wall insulation. Among them, most of the thermal insulation mortars are processed by organic materials (such as EPS thermal insulation mortar). This thermal insulation mortar made of organic materials has good thermal insulation properties. , Good chemical resistance and other advantages, but poor workability. In actual construction, there are shortcomings such as low bonding strength and difficult construction. Its physical and chemical properties are also unstable. Moreover, it emits harmful gases and is not resistant to high temperatures. At that time, it becomes a headache of white trash. At the same time, because EPS i...
