NOVELTY - A graphene composite corundum energy-saving sliding plate contains 25-45% alumina with a particle size of 1-3 mm, 16-25% tabular alumina with a particle size of 0-1 mm, 7-12% mullite, 7-20% silicon carbide, 0.5-1% Suzhou soil with a particle size of less than or equal to 0.088 mm, 2-5% graphite with a particle size of less than or equal to 0.045 mm, 6-10% zircon sand with a particle size of less than or equal to 0.045 mm, 1-2% silica fumes with a particle size of 2 mu m, 0.5-1.5% magnesium diboride, 0.5-2% boron, 0.5-1.5% aluminum fibers, 0.2 mol/l ammonium ferrous sulfate solution, and 4-6% composite resin binder. USE - Graphene composite corundum energy-saving sliding plate (claimed). ADVANTAGE - The graphene composite corundum energy-saving sliding plate has excellent oxidation resistance, thermal shock resistance and corrosion resistance. DETAILED DESCRIPTION - A graphene composite corundum energy-saving sliding plate contains 25-45% alumina with a particle size of 1-3 mm, 16-25% tabular alumina with a particle size of 0-1 mm, 7-12% mullite, 7-20% silicon carbide, 0.5-1% Suzhou soil with a particle size of less than or equal to 0.088 mm, 2-5% graphite with a particle size of less than or equal to 0.045 mm, 6-10% zircon sand with a particle size of less than or equal to 0.045 mm, 1-2% silica fumes with a particle size of 2 mu m, 0.5-1.5% magnesium diboride, 0.5-2% boron, 0.5-1.5% aluminum fibers, 0.2 mol/l ammonium ferrous sulfate solution, and 4-6% composite resin binder. The composite resin binder contains silicone resin, phenolic resin in a ratio of 3:1 and 1-3% polycarboxylic acid dispersant. An INDEPENDENT CLAIM is included for preparation of graphene composite corundum energy-saving sliding plate, which involves adding Suzhou soil, graphite, zircon sand, silica fumes and magnesium diboride to boron, uniformly mixing, grinding the mixture into 200 mesh or 325 mesh powder and then immersing in ammonium ferrous sulfate solution, adding silicone resin, phenol resin and polycarboxylic acid to the mixture and then stirring at 110 degrees C, premixing the mixture for 15-20 minutes and then soaking for 1 hour, drying the mixture and then ultrasonically dispersing for 10-20 minutes, adding alumina, tabular alumina, mullite, silicon carbide and aluminum fibers to the mixture and then blending for 2-3 minutes, soaking the mixture at 110 degrees C for 1 hour and then drying, premixing the mixture for 2-3 minutes and then grinding for 20-40 minutes, sieving the mixture using 5 mm sieve and then sealing for 24-36 hours, hydraulic pressing the mixture and then naturally drying at 260-350 degrees C for 24-48 hours, grinding the mixture, and packaging.
