Abstract

A novel red mud decorating and heat-insulation integrated light wall material is characterized by consisting of colored glass and a red mud iron reduction slag high-temperature melt foaming material. The colored glass consists of from 25 to 45 % of potash feldspar, from 20 to 40% of quartz, from 5 to 25% of calcite, from 4 to 8% of sodium borate, from 2 to 8% of barium carbonate, from 2 to 8% of zirconium silicate, from 2 to 6% of potassium nitrate and from 0 to 10% of ceramic color agent. The forming steps of the red mud iron reduction slag high-temperature melt foaming material include forming metallic iron and silicate slag by means of carbothermic reduction of red mud wastes; melting the metallic iron and silicate slag at high temperature; obtaining high-temperature melt of silicate slag after separation of molten iron; and foaming. The novel red mud decorating and heat-insulation integrated light wall material can be colorful after being added with the ceramic color agent, is a multifunctional high-grade interior and exterior wall decorating material with functions of decoration, heat insulation, sound insulation, seismic proofing and the like, is low in production cost, reduces environmental pollution, and is economical and environment-friendly. The wastes can be reused.

Description

technical field [0001] The invention relates to a novel lightweight wall material integrating red mud decoration and heat preservation, and belongs to the technical field of building ceramic preparation technology. Background technique [0002] Red mud decoration and heat preservation integrated new lightweight wall material is a new type of wall with integrated functions of decoration, heat preservation, waterproof, sound insulation and shock resistance, which is a combination of colored glass and red mud waste after iron removal and foaming materials Material.
