Novel red mud decorating and heat-insulation integrated light wall material

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.

At present, building materials generally use clay hollow bricks, cement hollow blocks, and aerated concrete blocks. A building decoration material with high manufacturing cost

[0003] Red mud, an industrial waste, is a waste produced during aluminum smelting and industrial alumina production, which causes serious pollution to the environment. There is no effective treatment method in the world.

At present, sintering method or Bayer red mud is mainly used as refractory materials, cement or various fillers, but due to poor product performance, high production cost and low added value, it cannot be widely used.

In addition, the above-mentioned red mud contains a large amount of iron, and if it is treated according to the above method, it will cause a lot of waste because the iron cannot be recovered.
