Embodiment 1

[0013] The first step: uniformly mix red mud and zirconium slag industrial waste at a weight ratio of 1:1 to make a mixed powder, add 40% water to make a slurry, and then mix the slurry with a particle diameter of 2mm to expand The perlite is uniformly mixed at a weight ratio of 100:20, and dried to make red mud-coated expanded perlite pellets;

[0014] The second step: then uniformly mix the expanded perlite fine powder with a particle size of 0.5mm, the mixed powder prepared in the first step, kaolin and ceramic coloring agent in a weight ratio of 10:10:77:3, and then add 1wt % sodium humate and 18wt% water are uniformly mixed to make plastic mud, extruded by a vacuum mud extruder to make a red mud expanded perlite plate with a thickness of 3mm and a width of 100mm and dried;

[0015] The third step: first use the left, right, front, back and bottom of the setter plate to form a cube setter mold with an upper opening, and coat the inner surface of the setter mold with a rele...

Embodiment 2

[0018] The first step: uniformly mix red mud and zirconium slag industrial waste at a weight ratio of 6.5:3.5 to make a mixed powder, add 50% water to make a slurry, and then mix the slurry with a particle diameter of 3.5mm Expanded perlite is evenly mixed with a weight ratio of 100:35, and dried to make red mud-coated expanded perlite pellets;

[0019] The second step: then mix the expanded perlite fine powder with a particle size of 0.3mm, the mixed powder prepared in the first step, kaolin and ceramic coloring agent in a weight ratio of 23:23:49:5, and then add 1.5 Wt% sodium humate and 22wt% water are uniformly mixed to make plastic mud, extruded by a vacuum mud extruder to make red mud expanded perlite boards with a thickness of 11mm and a width of 300mm and dried;

[0020] The third step: first use the left, right, front, back and bottom of the setter plate to form a cube setter mold with an upper opening, and coat the inner surface of the setter mold with a release agen...

Embodiment 3

[0023] The first step: uniformly mix red mud and zirconium slag industrial waste at a weight ratio of 8:5 to make mixed powder, add 60% water to make mud, and then mix the mud with a particle diameter of 5mm to expand The perlite is evenly mixed in a weight ratio of 100:50, and dried to make red mud-coated expanded perlite granules;

[0024] The second step: then mix the expanded perlite fine powder with a particle size of 0.1mm, the mixed powder prepared in the first step, kaolin and ceramic coloring agent in a weight ratio of 35:35:20:10, and then add 2wt % sodium humate and 25wt% water are uniformly mixed to make plastic mud, extruded by a vacuum mud extruder to make a red mud expanded perlite plate with a thickness of 20mm and a width of 500mm and dried;

Abstract

The preparation method of red mud expanded perlite decorative and thermal insulation integrated light wall material is characterized in that: the red mud expanded perlite decorative thermal insulation integrated light wall material is formed by extruding red mud expanded perlite board and red mud Coated expanded perlite pellets are fired at high temperature. The red mud expanded perlite decoration and heat preservation integrated light wall material prepared by the present invention adopts one-time firing, and the surface decoration is made of red mud expanded perlite board through extrusion molding, so that the wall material has six sides. Color decoration, strong integrity, and then prepared by adding ceramic colorants to make single-color, composite color and other colors and patterns of interior and exterior wall decoration materials, no additional decoration is required, the production process is simple, the cost is low, the building insulation effect is good, energy saving, Environmental protection, the production of red mud expanded perlite decorative and thermal insulation integrated lightweight wall material integrates multiple functions such as decoration, thermal insulation, waterproof, thermal insulation, sound insulation and shockproof properties.

Description

technical field [0001] The invention relates to a preparation method of red mud expanded perlite decoration and heat preservation integrated light wall material, and belongs to the technical field of ceramic preparation. Background technique [0002] Red mud expanded perlite decorative and thermal insulation integrated lightweight wall material is a new type of lightweight wall material that integrates decoration and thermal insulation. It is a decorative wall material that uses colored microcrystalline glass. A new type of wall material that integrates thermal, waterproof, sound insulation and shockproof functions. At present, building materials generally use clay hollow bricks, cement hollow blocks and aerated concrete blocks, etc. These building materials have poor thermal insulation performance and decorative performance. When applied to interior and exterior walls, additional tiles or wallpapers are required, which is a high manufacturing cost. of building materials. ...
