Embodiment 1
[0025] A thermal insulation mortar, including the following raw materials: 80kg of river bottom sludge, 20kg of coated nano-fly ash, 15kg of lime paste, 10kg of attapulgite powder, 10kg of sanidine powder, 10kg of floating beads, 5kg of silicon-calcium powder, and 6kg of phenolic foam particles , barium stearate 4kg, polystyrene fiber 8kg, redispersible latex powder 3kg, foaming agent 1kg, foam stabilizer 1kg and early strength agent 1kg;
[0026] The preparation method of the coated nano fly ash is as follows: the fly ash is ball-milled and dispersed with alcohol for 2 hours, and then 2% of the weight of the alkyl glucoside, 1% of tricresyl phosphate and 7% of the Deionized water was stirred and heated in a constant temperature water bath at 60°C for 40 minutes to obtain a dispersion, and then an aluminum sulfate solution with a concentration of 25% equivalent to 10% of its weight was added to the dispersion, and an appropriate amount of ammonia water was added to adjust the p...
