Modified phosphogypsum lightweight thermal insulation building block and preparation method thereof
The invention discloses a modified phosphogypsum lightweight thermal insulation building block and a preparation method thereof, and relates to the technical field of building materials. The building block is prepared from the following raw materials in parts by weight: 86 to 120 parts of modified phosphogypsum primary material, 1.5 to 2 parts of sodium silicate, 4 to 5 parts of quick lime, 35 to 45 parts of water, 25 to 35 parts of cement, 0.15 to 0.3 part of polyaluminum chloride, 0.2 to 0.3 part of calcium formate, 0.01 to 0.02 part of rubber powder, 0.03 to 0.05 part of cellulose ether, 0.2 to 0.3 part of sodium hydroxide, 0.2 to 0.3 part of water reducing agent and 0.06 to 0.08 part of aluminum powder paste. The indexes of the prepared modified phosphogypsum lightweight thermal insulation building block meet the related requirements of GB/T11968-2020, the product strength is high, the heat conductivity coefficient is low, heat transfer can be effectively prevented, the thermal insulation performance effect is more prominent, the modified phosphogypsum is adopted as the main raw material, the utilization rate of the phosphogypsum is increased, and the cost is reduced. Air entraining foaming is achieved, the volume weight is reduced, light texture is achieved, resource utilization of industrial waste residues is achieved, environmental pollution is effectively reduced, low carbon and energy saving are achieved, and the production efficiency is high.
本发明公开了一种改性磷石膏轻质保温砌块及其制备方法，涉及建材技术领域，所述砌块按重量份计包含以下组分原料:改性磷石膏初料86‑120份、硅酸钠1.5‑2份、生石灰4‑5份、水35‑45份、水泥25‑35份、聚合氯化铝0.15‑0.3份、甲酸钙0.2‑0.3份、胶粉0.01‑0.02份、纤维素醚0.03‑0.05份、氢氧化钠0.2‑0.3份、减水剂0.2‑0.3份、铝粉膏0.06‑0.08份。本发明所制成的改性磷石膏轻质保温砌块指标符合GB/T11968‑2020的相关要求，产品强度高，其导热系数低，能够有效阻止热量的传递，保温隔热性能效果更为突出，本发明保温砌块采用了改性处理后的磷石膏作为主要原料，提高了磷石膏利用率，引气发泡，降低容重，实现轻质质地，实现了工业废渣的资源化利用，有效减少环境污染，低碳节能，生产效率高。
