Geopolymer foaming cement thermal insulation material and preparation method thereof
The invention discloses a geopolymer foam cement thermal insulation material and a preparation method thereof. The geopolymer foam cement thermal insulation material comprises the following raw materials: 100 parts of municipal solid waste incineration bottom ash, 30-80 parts of a silicon-rich aluminum raw material, 5-25 parts of a magnesium ingredient, 35-70 parts of a liquid alkali activator, 0.5-2 parts of a thickening agent and 0.5-3 parts of a foam stabilizer. The raw materials are mixed to obtain geopolymer slurry, and then the geopolymer slurry is subjected to hydrothermal curing to obtain the geopolymer foam cement thermal insulation material. The MSWI bottom ash is used as a base body, harmless treatment and high-value resource utilization of the MSWI bottom ash are achieved, the preparation method is easy to operate, the MSWI bottom ash can be directly used, chemical foaming can be achieved without pretreatment and additional adding of a foaming agent, and the material production cost is effectively saved. The obtained foam cement thermal insulation material has excellent properties, the doped magnesium ingredient can effectively inhibit alkali permeation and weathering phenomena, and the filtered heavy metal ions meet the limit value requirements of solid waste leaching toxicity identification standards.
本发明公开了一种地质聚合物发泡水泥保温材料及制备方法，原料包括100份城市生活垃圾焚烧底灰、30‑80份富硅铝质原料、5‑25份镁质配料、35‑70份液体碱激发剂、0.5‑2份增稠剂和0.5‑3份稳泡剂。将各原料混合得到地质聚合物浆体，再进行水热养护后得到地质聚合物发泡水泥保温材料。本发明以MSWI底灰为基体，实现了MSWI底灰的无害化处理和高值化资源利用，制备方法易于操作，MSWI底灰可直接使用，无需预处理，无需额外掺加发泡剂便可实现化学发泡，有效节约了材料生产成本。所得发泡水泥保温材料的各项性能优异，掺入的镁质配料可有效抑制渗碱风化现象，重金属离子滤出满足固体废物浸出毒性鉴别标准的限值要求。
