Calcium carbonate-carbon nanotube co-coated magnesium-calcium refractory material and preparation method thereof
The invention relates to a calcium carbonate-carbon nanotube co-coated magnesium-calcium refractory material and a preparation method thereof. According to the technical scheme, the method comprises the following steps: adding an elemental catalyst or a compound precursor into the magnesium-calcium refractory material, and uniformly stirring to obtain the magnesium-calcium refractory material of which the surface is loaded with more than one of Fe, Co and Ni. Placing the waste oil and the magnesium-calcium refractory material with the surface loaded with more than one of Fe, Co and Ni in an atmosphere furnace according to the mass ratio of the waste oil to the magnesium-calcium refractory material with the surface loaded with more than one of Fe, Co and Ni of 1: (1-5); and heating to 500-1000 DEG C at the rate of 2-10 DEG C/min in an inert atmosphere, reacting for 0.5-5 hours, and cooling along with the furnace to obtain the calcium carbonate-carbon nanotube co-coated magnesium-calcium refractory material. The method is simple in process, controllable in operation, low in pyrolysis temperature requirement and high in safety; the prepared product has the characteristics of super-hydrophobicity, good hydration resistance, high bonding strength of the coating layer and good high temperature resistance.
