Nano silicon dioxide-bottom ash geopolymer thermal insulation material and preparation method thereof
The invention discloses a nano silicon dioxide-bottom ash geopolymer thermal insulation material and a preparation method, the nano silicon dioxide-bottom ash geopolymer thermal insulation material comprises nano silicon dioxide, bottom ash and water, and the mass ratio of the nano silicon dioxide to the bottom ash to the water is (250-350): (250-350): (150-210). According to the nano silicon dioxide-bottom ash geopolymer thermal insulation material and the preparation method, nano silicon dioxide with a high additional utilization value is obtained through sludge purification, so that the purpose of resource utilization of dredged sludge is achieved, and through alkaline water thermal activation treatment, the utilization rate of the dredged sludge is increased. The activity of the geopolymerization reaction of the sludge purification product can be greatly improved, the use of an alkali activator is eliminated, the geopolymerization reaction can be completed only by adding water, and the nano silicon dioxide precursor is thermally activated by combining the property that the elemental aluminum in the waste incineration bottom ash and the alkali activator generate hydrogen; the foam geopolymer material which is low in cost, high in performance and environmentally friendly is prepared, and dual utilization of bottom ash and dredged sludge is achieved.
