Description

technical field [0001] The invention belongs to the technical field of thermal insulation materials for building walls, and relates to an energy-saving composite thermal insulation mortar for walls. Background technique [0002] While the appearance of urban and rural areas has undergone tremendous changes, people have built a large number of buildings, but these buildings need to use a lot of building materials and consume a lot of non-renewable resources and energy, especially some buildings with poor thermal insulation, making winter Excessive heating causes environmental pollution, and cooling in summer causes power supply shortages, and also causes a large amount of energy consumption. Therefore, wall insulation is particularly important in building energy saving, and it is also an important link in building energy saving. The traditional way of thermal insulation of building walls in our country is to thicken the thickness of the wall to achieve the purpose of thermal...

AI Technical Summary

Problems solved by technology

The traditional building wall insulation in our country is to use the method of thickening the wall thickness to achieve the purpose of insulation, not only the cost of the project is high, but also the waste of land resources is serious

With the needs of building development, a large number of wall insulation materials have also emerged. However, most wall insulation materials either consume a lot of building material resources and are expensive, or the strength of the material itself is not enough. In practical applications The quality is unstable, and the wall insulation layer is thicker, which is prone to hollowing, cracking, pulverization and other defects, which affects the quality of the building, and it is difficult to meet the standards of thermal insulation and energy saving.

At present, there are many wall insulation materials in the construction market, such as: one is the wall insulation board of the plate type, the existing problems are: the production process is complicated, it takes up a lot of space, and the wall insulation layer made of it has poor compression resistance , prone to cracks; the other is closed-cell vitrified microbead insulation material. After the material expands, the surface is uranized for waterproofing, but the cohesion of the uranized material is poor, and it is prone to hollowing, hollowing, and The phenomenon of cracking, for this reason, special adhesives and anti-cracking agents must be used in use, so the production cost is high

Another kind of wall insulation slurry material is made of asbestos, perlite, reinforcing agent, binder and water. Although it can achieve a certain insulation effect, its quality is unstable during use and transportation is also very difficult. It is convenient, and the asbestos in the material contains carcinogens that are harmful to human health. It is a restricted and banned material in the country, so it is inconvenient to promote and apply
