Thermal-insulation decoration board and production method thereof

The invention provides a thermal-insulation decoration board and a production method thereof. The thermal-insulation decoration board is characterized in that a decoration layer comprises, by weight, 26-38 parts of iron tailings, 15-28 parts of kaolin, 30-46 parts of waste ceramic tiles, 12-18 parts of talcum and 16-22 parts of quartz; a thermal-insulation layer comprises, by weight, 40-60 parts of sludge, 6-8 parts of dickite, 12-18 parts of kaolin, 8-12 parts of feldspar, 3-4 parts of calcite, 6-8 parts of dolomite, 0.2-0.4 parts of modifier, 0.8-1.1 parts of stabilizer and 0.5-1.2 parts of SiC. The thermal-insulation decoration board and the production method thereof have the advantages that the thermal-insulation layer and the decoration layer are sintered after being stacked up and down, the process flow is shortened, and the binding strength between the thermal-insulation layer and the decoration layer is enhanced; the produced thermal-insulation decoration board is thermal-insulating, attractive in appearance, green, energy-saving, efficient in construction, capable of beautifying environments, and the like; due to the fact that the thermal-insulation layer and the decorating layer use the iron tailings, waste ceramic tiles, sludge and the like as the raw materials, waste resources are reused efficiently, environments are protected, and production cost is lowered.
