The calcium silicate cement board is prepared from the following raw materials in parts by weight: paper mill sludge, Zr-containing silica residues, coal ash, slag powder, portland cement, straw fibers, ceramic fibers, a PC water reducer, an SM water reducer, water, alumina powder, talc powder, zinc oxide, antimony oxide, sodium silicate and silicon nitride, wherein the paper mill sludge comprises the following components by weight: 30-40 kg of plant fibers, 1.4 kg of aluminum oxide, 7.95 kg of silicon dioxide, 1.15 kg of ferric oxide, 45.6 kg of calcium oxide and 2.5 kg of magnesium oxide; the mass fraction of silicon dioxide in Zr-containing silica residues is 85.3%; slag powder comprises the following components by weight: 15.6 kg of silicon oxide, 6.58 kg of aluminum oxide, 32.8 kg of calcium oxide and 4.68 kg of magnesium oxide.

Description

technical field [0001] The invention relates to the technical field of calcium-silicon board production, in particular to a calcium-silicon cement board for green prefabricated building walls and a production method thereof. Background technique [0002] Calcium silicate board is mainly composed of gypsum, while calcium silicate is composed of quartz, mica, wood fiber and other components. Calcium silicon board can be used for indoor ceilings, and has the characteristics of moisture resistance, fire resistance, antifouling, low carbon, clean surface and good durability. The cost of the calcium silicon board in the prior art is relatively high. [0003] The lime mud produced in the papermaking process is generally disposed of by landfill or stacking, which takes up a lot of land resources and pollutes groundwater. Zirconium silicon slag is also a kind of industrial waste, which is generally stacked in the open air, which has an impact on the surrounding environment. C...
