Problems solved by technology

[0004] New wall materials generally have many advantages such as heat preservation, heat insulation, light weight, high strength, energy saving and environmental protection, improvement of building functions, and increase of housing usable area. However, in practical engineering applications, there are still many problems with common new wall materials, such as product High bulk density (mostly 800kg / m 3 above), high thermal conductivity (greater than 0.19W / (m K)), energy-saving and thermal insulation performance still needs to be improved, the crack resistance and shock resistance of materials need to be enhanced, and the appearance quality of products also needs to be improved. The above problems are very serious. To a certain extent, it restricts the application field and promotion effect of new wall materials

Abstract

Disclosed is a manufacturing method of a novel high-strength light-weight ceramic thermal-insulation wall material. According to the method, a series of technical problems that novel wall materials in the prior art is large in unit weight and poor in energy-saving and thermal-insulation effect are mainly solved. According to the method, polished waste residues are taken as a raw material; a certain mass of raw mineral and chemical industrial materials are added; ball-milling mixing, spray granulation, and die-filling are carried out; and high-temperature sintering at 1150-1250 DEG C is carried out to manufacture the novel wall material. The novel wall material has a unit weight of 300-500 kg/m3, a heat conductivity coefficient of 0.06-0.15 w/(m*K), and a compressive strength of 4.5-12 MPs. The novel wall material has characteristics of low unit weight and heat conductivity coefficient, high compressive strength, excellent thermal-insulation performance, and good fireproof performance.
