[0015] The present invention is described in detail below in conjunction with the examples, the purpose is only to better understand the contents of the present invention, and the examples given are not intended to limit the contents of the present invention.
[0016] A method for preparing a refractory material binder by oxidizing waste water sludge from an aluminum alloy profile factory is carried out according to the following steps:
[0017] (1) Take the sludge recovered from the oxidation wastewater treatment of the aluminum material factory, the chemical composition of the sludge is calculated by weight percentage: Al 2 o 3 60.50, SiO 2 2.15, Na 2 O 1.67, CaO 0.22, SO 3 2.15, P 2 o 5 1.30, loss on ignition 32.01; after washing and suction filtration, according to the dry weight of sludge, add sludge accounting for 20% of the total weight of raw materials into the reaction vessel;
[0018] (2) Add water accounting for 30% of the total weight of raw materials int...
