The invention discloses an aluminum oxide ceramics eyelet with a long service life. The aluminum oxide ceramics eyelet with the long service life is prepared from the following raw materials in parts by weight: 6 to 10 parts of zirconia powder, 1 to 3 parts of dolomite powder, 60 to 70 parts of aluminium oxide, 1 to 3 parts of titanium carbide, 0.2 to 0.4 part of polymethyl methacrylate, 2 to 5 parts of kieselguhr, 1 to 3 parts of kaolin, 1 to 2 parts of silicon carbide, 1 to 3 parts of mica powder, 2 to 4 parts of rutile type titanium dioxide, 0.2 to 0.4 part of chlorcosane, 0.1 to 0.2 part of stearic acid, 1 to 2 parts of polyethylene glycol, 1 to 2 parts of rosin resin, 1 to 2 parts of hydroxyethyl cellulose, 6 to 8 parts of ethyl alcohol, and 7 to 15 parts of deionized water. In a formula of the invention, acid and alkali-resistant titanium dioxide, mica powder and titanium carbide are taken as the raw materials, the hardness and the acid and alkali resistance of the prepared ceramics materials are improved, and the service life of the ceramics eyelet is prolonged.
