Anti-corrosion aerated building block and preparation method thereof
The invention discloses an anti-corrosion aerated building block and a preparation method thereof, and belongs to the technical field of building materials, the anti-corrosion aerated building block comprises the following raw materials by weight: 5-10 parts of cement powder, 20-30 parts of fly ash, 0.8-1 part of modified aluminum powder, 50-70 parts of a gypsum/fiber composite material, and 2-5 parts of fine sand. In the process of modifying the aluminum powder, the acrylic resin has a good wrapping and modifying effect on the aluminum powder, and after the aluminum powder is wrapped by the acrylic resin, the hydrogen evolution amount of the aluminum powder can be greatly reduced, so that the corrosion resistance of the aerated building block can be enhanced by improving the corrosion resistance of the aluminum powder; the surface of the aluminum powder is coated with the silane and the acrylic resin, so that the dispersity and stability of the aluminum powder can be improved, the strength of the corrosion-resistant aerated building block can be enhanced by doping the gypsum/fiber material, and the self weight of the corrosion-resistant aerated building block can be reduced on the basis; the obtained corrosion-resistant aerated building block has the effects of light weight, sound insulation, heat insulation, high stability, fire prevention and energy conservation.
本发明公开了一种抗腐蚀加气砌块及其制备方法，属于建筑材料技术领域，包括如下重量份的原料：水泥粉5‑10份、粉煤灰20‑30份、改性铝粉0.8‑1份、石膏/纤维复合材料50‑70份、细砂2‑5份。本发明中，在对铝粉进行改性的过程中，丙烯酸树脂对铝粉具有良好的包裹改性效果，铝粉被丙烯酸树脂包裹后，能够大大降低铝粉的析氢量，从而能够通过提升铝粉的耐腐蚀性能增强加气砌块的抗腐蚀能力，通过将硅烷和丙烯酸树脂包裹在铝粉的表面，从而能够提升铝粉的分散性以及稳定性，通过掺入石膏/纤维材料能够增强抗腐蚀加气砌块的强度，并在此基础上还能够降低抗腐蚀加气砌块的自重，使得获得的抗腐蚀加气砌块具有质轻、隔音隔热、稳定性高以及防火节能的效果。
