Preparation method of light-weight heat-preservation brick
The invention discloses a preparation method of light-weight heat-preservation bricks. The preparation method includes the steps of 1) mixing the following raw materials comprising: 50-76% of industrial coal slag, 6-20% of a mud material, 4-20% of potassium feldspar, 4-20 parts of sodium feldspar, 4-20% of quartz and 0-15% of polishing residue, and performing ball milling, spraying and moulding to produce a green body; (2) drying the green body; (3) sintering the green body; (4) after-treating the sintered green body, and packaging a finish product. The preparation method is simple in step, is short in sintering time and can save energy resources. The produced heat-preservation brick is solid in texture, is low in specific gravity, is high in porosity, is higher than 1000 DEG C in resistance temperature, can easily resist common fire, is low in heat conductivity and high in pressure resistant strength, and is very suitable for heat insulation of outer walls and indoor heat insulation and sound insulation.
