Nanocrystalline composite foamed ceramic assembly type wall masonry material and manufacturing method thereof

Abstract

The invention relates to a method for manufacturing a nanocrystalline composite foamed ceramic assembly type wall masonry material and a nanocrystalline composite foamed ceramic assembly type wall masonry material manufactured by adopting the method. The wall masonry material is prepared by the following steps: firing nanocrystalline frits by taking inorganic nonmetallic materials as raw materials, mixing the nanocrystalline frits with a mixed material prepared from foamed ceramic inorganic materials at an appropriate heat treatment firing temperature by using a controlled crystallization technology, and crystallizing the particles at a high-temperature heat treatment firing temperature, thereby obtaining the fired nanocrystalline composite foamed ceramic assembly type wall masonry material. The wall masonry material manufactured by the method is excellent in physical mechanical properties, compressive property, soundproof effect and stability, and has the advantages of being resistantto pollution, free in radioactive element, green, environmental-friendly, excellent in fireproof and flame retardant safety performance, anti-freezing, corrosion-resistant, aging-resistant and the like.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a method for producing nano-microcrystalline composite foamed ceramic prefabricated wall masonry materials by using waste coal gangue and potassium feldspar tailings. Background technique [0002] Walls are an important part of buildings, generally divided into interior walls and exterior walls. At present, most of the walls are made of brick-concrete or concrete materials, which can meet general construction requirements such as strength, stability and sound insulation. However, in order to achieve better architectural requirements such as thermal insulation, fire prevention, moisture resistance, and aesthetics, the walls built with brick-concrete materials also need to add materials and processes such as thermal insulation material layers, fire-resistant and moisture-proof coating material layers, or exterior building material layers. Therefore, the construction cost is gr...

AI Technical Summary

Problems solved by technology

However, in order to achieve better architectural requirements such as thermal insulation, fire and moisture resistance, and aesthetics, the walls built with brick-concrete materials also need to add materials and processes such as thermal insulation material layers, fire-proof and moisture-proof coating material layers, or exterior building material layers. , so the construction cost is greatly increased, it takes longer, and sometimes it causes unnecessary pollution to the external environment of the building

[0003] In the prior art, there are also some buildings that use external stone as the facade, thereby improving the decorative effect, but the cost of using this decorative material is high, the process is complicated, and it is impossible to effectively improve thermal insulation, fire prevention and moisture resistance, etc.
