▎ 摘  要

NOVELTY - Preparing aluminum-based carbon slide comprises (i) taking plate-shaped corundum, white corundum, aluminum powder, alpha-aluminum oxide micropowder, graphene and phenolic resin, (ii) uniformly mixing plate-shaped corundum and white corundum in a ratio of 50-60:20-30 to obtain aggregates, uniformly mixing aluminum powder, alpha -Al2O3 fine powder and graphene in a ratio of 10-20:10-20:40-60 to obtain fine powder, and uniformly mixing the aggregate and the fine powder in a ratio of 30-40:60-80 to obtain mixed raw materials, (iii) uniformly mixing the mixed raw material with the phenolic resin, and using the phenolic resin to bond the mixed raw materials, (iv) placing the mixed raw materials mixed into a mold, and pressing into a brick by a friction press, (v) placing the bricks in a cool place and drying, and placing into a drying kiln and drying, (vi) placing the treated brick into a shuttle raft, heating, and sintering the brick blank, and (vii) processing into a carbon plate. USE - The method is useful for preparing aluminum-based carbon slide. DETAILED DESCRIPTION - Preparing aluminum-based carbon slide comprises (i) taking plate-shaped corundum, white corundum, aluminum powder, alpha -Al2O3 micropowder, graphene and phenolic resin, (ii) uniformly mixing plate-shaped corundum and white corundum in a ratio of 50-60:20-30 to obtain aggregates, uniformly mixing aluminum powder, alpha -Al2O3 fine powder and graphene in a ratio of 10-20:10-20:40-60 to obtain fine powder, and uniformly mixing the aggregate and the fine powder in a ratio of 30-40:60-80 to obtain mixed raw materials, (iii) uniformly mixing the mixed raw material with the phenolic resin in a ratio of 80-85:8-15, and using the phenolic resin to bond the mixed raw materials, (iv) placing the mixed raw materials mixed into a mold, and pressing into a brick by a friction press of more than 650 tons, (v) placing the bricks in a cool place and drying for 30-40 hours, and placing into a drying kiln and drying at 250-300 degrees C for 10-15 hours, (vi) placing the treated brick into a shuttle raft, heating at 1300-1600 degrees C for 6-10 hours under carbon-buried conditions, and sintering the brick blank, and (vii) processing into a carbon plate.
