The invention discloses a ternary composite self-repairing unfired sliding plate
brick and a preparation method thereof. The ternary composite self-repairing unfired sliding plate
brick is prepared from the following components in percentage by
mass: 5 to 10 parts of
macrocrystalline fused
magnesite with the particle size of 3 to 1mm, 15 to 25 parts of
macrocrystalline fused
magnesite with the particle size of 2 to 1mm, 5 to 15 parts of
macrocrystalline fused
magnesite with the particle size of 1 to 0.5 mm, 5 to 10 parts of macrocrystalline fused magnesite with the particle size of 0.5 to 0mm, 12 to 20 parts of 200-mesh macrocrystalline fused magnesite, 1 to 4 parts of -197
graphite, 0.5 to 3 parts of Al4SiC4 micro
powder, 0.5 to 2 parts of nano SiC micro
powder, 3 to 8 parts of 325-mesh
metal Al powder, 0.5 to 3 parts of 200-mesh
metal Si
powder, 0.5 to 2 parts of
boron carbide, 0.5 to 1 part of
silicon boride, 2 to 4 parts of thermosetting phenolic resin and 2 to 4 parts of organic
silicon resin. The ternary composite self-repairing sliding plate
brick has a self-repairing function when being used at high temperature, and the
oxidation resistance and high-temperature stability of a sliding plate are remarkably improved.
