Autoclaved aerated concrete plate and preparation method thereof
The invention provides an autoclaved aerated concrete plate and a preparation method thereof, and belongs to the technical field of novel building materials. The autoclaved aerated concrete plate is prepared from the following substances in parts by mass: 50 to 65 parts of fly ash, 3 to 10 parts of gypsum, 15 to 25 parts of solid waste slurry, 7 to 10 parts of cement, 9 to 13 parts of lime, 0.02 to 0.08 part of aluminum powder paste and 0.1 to 1 part of hydrophobic particles. Wherein the hydrophobic particles comprise nano-particles and low-surface-energy substances attached to the surfaces of the nano-particles. According to the autoclaved aerated concrete plate provided by the invention, a multi-stage nano-structure is constructed on the surface of the autoclaved aerated concrete plate and in the air holes by utilizing the nano-particles of which the surfaces are attached with the low-surface-energy substances, so that the overall hydrophobicity of the material and the plate is improved from inside to outside, and the autoclaved aerated concrete plate has a good heat preservation effect and corrosion resistance.
本申请提供了一种蒸压加气混凝土板材及其制备方法，属于新型建筑材料技术领域。蒸压加气混凝土板材按照质量份数包括如下物质：粉煤灰50‑65份、石膏3‑10份、固废浆料15‑25份、水泥7‑10份、石灰9‑13份、铝粉膏0.02‑0.08份、疏水颗粒0.1‑1份；其中，疏水颗粒包括纳米颗粒，以及附着在纳米颗粒表面的低表面能物质。本申请提供的蒸压加气混凝土板材，利用表面附着低表面能物质的纳米颗粒在其表面及气孔内部构建多级纳米结构，由内而外地改善材料自身及板材的整体疏水性，并且具有良好的保温效果和抗腐蚀性能。
