Unfired sliding plate added with flaky metal aluminum powder and colloidal graphite and preparation method of unfired sliding plate

The invention relates to an unfired sliding plate added with flaky metal aluminum powder and colloidal graphite and a preparation method of the unfired sliding plate, and the unfired sliding plate comprises the following raw materials: 45-55% of dense sintered corundum, 32-42% of fused dense corundum, 5-10% of flaky metal aluminum powder, 1-3% of colloidal graphite, 6-10% of superfine aluminum oxide micro powder and 1-3% of metal aluminum fibers, adding 2-5% of phenolic resin powder and 1-5% of furfuryl alcohol; during production, the raw materials are weighed according to the proportion, mixed and mixed into pug, and the pug is subjected to ageing, forming, drying, hooping, grinding and coating to obtain the product. The product is excellent in medium-high temperature strength, oxidation resistance, thermal shock resistance and erosion resistance, the apparent porosity is 3-8%, the volume density is 3.10-3.25 g/cm < 3 >, the normal-temperature compressive strength is 120-200 MPa, the high-temperature breakin
