Calcium silicate board and preparation method thereof
The invention discloses a calcium silicate board and a preparation method thereof, belonging to the technical field of inorganic boards. The preparation method of the calcium silicate board comprises the following steps: mixing iron oxide green, a dispersing agent and water to obtain a mixed solution; mixing a white material, tailings and stone powder to obtain a mixture; mixing the mixed solution and the mixture to obtain a wet material; pressing the wet material into a green body, drying the green body at 30-60 DEG C until a water loss rate reaches 50-70%, and then taking out the green body to obtain a calcium silicate substrate; and carbonizing the calcium silicate substrate in a vacuum CO2 environment to obtain the calcium silicate board. The calcium silicate board is high in breaking strength, low in water absorption rate and high in carbonization degree.
本发明公开一种硅酸钙板及其制备方法，属于无机板材技术领域。该硅酸钙板的制备方法，包括以下步骤：将氧化铁绿、分散剂和水混合得到混合液；将白料、尾矿和石粉混合得到混合物；将所述混合液和所述混合物混合得到湿料；将所述湿料压制为坯体，将坯体在30‑60℃下干燥至失水率达到50‑70％后取出，得到硅酸钙基板；将所述硅酸钙基板在真空CO2环境下碳化得到所述硅酸钙板。该硅酸钙板抗折强度强、吸水率低、碳化程度高。
