High-dosage water-resistant phosphogypsum building material and preparation method thereof
The invention relates to the technical field of industrial waste residue utilization, in particular to a high-dosage water-resistant phosphogypsum building material and a preparation method thereof. The preparation method of the high-dosage water-resistant phosphogypsum building material comprises the following steps: uniformly stirring phosphogypsum, nano silicon dioxide, water and a water reducing agent to prepare phosphogypsum slurry, and carrying out mold filling, curing and forming to prepare a body modified phosphogypsum building material; and obtaining a hydrophobic coating and carrying out waterproof treatment on the surface of the body modified ardealite building material to obtain the body modified ardealite building material. The hydrophobic coating comprises the following raw materials: a silane coupling agent, a solvent, ammonia water and nano titanium dioxide. The hydrophobic property, the corrosion resistance, the self-cleaning property and the antibacterial property of the ardealite building material are improved through a dual modification method, meanwhile, the mechanical property of the ardealite building material is improved, and in addition, the ardealite is high in utilization rate, more environmentally friendly and high in practical value and application prospect.
本发明涉及工业废渣利用技术领域，具体涉及一种高掺量耐水型磷石膏建材及其制备方法。其中，一种高掺量耐水型磷石膏建材的制备方法，包括：将磷石膏与纳米二氧化硅、水和减水剂搅拌均匀制成磷石膏浆体，装模养护成型制得本体改性磷石膏建材；获取疏水涂料并对本体改性磷石膏建材的表面进行防水处理即得；所述疏水涂料的原料包括硅烷偶联剂、溶剂、氨水和纳米二氧化钛。本发明通过双重改性的方法在提升磷石膏建材的疏水性能、耐腐蚀性能、自清洁性能、抗菌性能的同时，也使磷石膏建材的力学性能得以提升，另外，本发明磷石膏的利用率高，更加绿色环保，有很大的实用价值和应用前景。
