Ceramic black material for absorbing infrared thermal radiation and preparation method thereof

The invention provides a ceramic black material. The ceramic black material comprises the following raw materials in parts by weight: 20-30 parts of ferric oxide, 15-30 parts of aluminum oxide, 10-15parts of zirconium oxide, 15-20 parts of metal oxide infrared-radiation micropowder, 20-25 parts of an adhesive, 0.15-0.25 part of a dispersing agent, 0.4-1.5 parts of a thickening agent, 0.05-0.10 part of a defoaming agent and 0.02-0.8 part of a mildew preventive, wherein the metal oxide infrared-radiation micropowder is formed by grinding and mixing aluminum oxide micropowder and titanium carbide-cordierite radiation micropowder according to a weight ratio of 2: 1. The preparation method of the ceramic black material capable of absorbing infrared heat radiation comprises the following steps:(1) proportioning; (2) mixing; (3) sieving; (4) pulping; (5) drying; (6) grinding; and (7) high-temperature treatment. According to the invention, the black material has the advantages of wear resistance, high infrared heat r
