The invention discloses a
porous medium burner material. The
porous medium burner material comprises
ceramic powder, a binding agent, a dispersing agent and a suspending agent, wherein the
ceramic powder consists of the following components in percentage by weight: 15 to 40 percent of zirconite
powder, 30 to 50 percent of fine
mullite powder, 5 to 10 percent of fine
zirconium oxide powder, 10 to 20 percent of
soft clay, 5 to 10 percent of active aluminum
oxide powder and 1 to 5 percent of
silicon dioxide micro powder; the binding agent is 30 to 45 percent based on the total weight of the
ceramic powder; the dispersing agent is 0.1 to 0.5 percent based on the total weight of the ceramic powder; the suspending agent is 0.2 to 1.0 percent based on the total weight of the ceramic powder; and the particle size of the
fine powder is not greater than 250 meshes. The preparation method of the
porous medium burner material comprises the following steps of: preprocessing organic foamed plastic; performing ball-milling on the ceramic powder, the additional binding agent, an additive and a proper amount of water; adding an antifoaming agent into the mixture, performing ball milling to obtain uniform paste, and controlling the
viscosity to be 1 to 5Pa.s; soaking the preprocessed organic foamed plastic in the paste; repeating the processes for several times until the required density is achieved; removing the excessive paste to obtain the porous biscuit; naturally
drying the porous biscuit at the
room temperature;
drying the biscuit in a
drying box of over 90 DEG C to control the
moisture to be less than or equal to 1.0 weight percent; and firing the biscuit in a
kiln to obtain the porous medium.
