Method for preparing wall thermal insulation material from industrial solid waste
The invention discloses a method for preparing a wall thermal insulation material from industrial solid waste. The method comprises the following steps: respectively drying, grinding and screening copper slag, fly ash and phosphogypsum to 80-100 meshes; proportioning according to a certain proportion and a certain adding sequence; selecting quick lime as an exciting agent, and selecting a mixtureof alpha-olefin sodium sulfonate, sodium dodecyl benzene sulfonate and sodium alcohol ether sulphate as a foaming agent; and sequentially mixing quick lime, a small amount of water, phosphogypsum andauxiliary materials, cement and a cement foaming agent to prepare slurry, molding by casting, naturally standing and drying for 24 hours, and heating and drying in a thermostat for 24 hours to obtainthe building wall thermal insulation material. The method has the advantages that the solid waste phosphogypsum is not subjected to desulfurization treatment, the copper slag is directly utilized, andother auxiliary raw materials are added to react with substances in the copper slag, so that an impurity removal effect is achieved; three anionic surfactants with less research are selected as the cement foaming agent; and the process is simple and easy to implement, and the prepared thermal insulation material is natural, pollution-free and excellent in performance.
本发明公开了一种利用工业固废制备墙体保温材料的方法，其将铜渣、粉煤灰和磷石膏分别干燥、研磨、筛分至80‑100目；按比例和一定的添加顺序进行配料；选用生石灰作为激发剂，α‑烯烃磺酸钠、十二烷基苯磺酸钠和脂肪醇聚氧乙烯醚硫酸钠三种混合物作为发泡剂；采用生石灰→少量水→磷石膏+辅料→水泥→水泥发泡剂的加料顺序混料配制成浆料后，浇注成型，经自然静停干燥24h、恒温箱加热干燥24h后，得到建筑墙体保温材料。本发明的优点：固体废物磷石膏不进行脱硫处理，铜渣直接利用，通过加入其他辅助原料与其中的物质反应，以达到除杂作用；选用三种研究较少的阴离子型表面活性剂共同作为水泥发泡剂；工艺简单易行，制得的保温材料天然无污染且性能优越。
