The invention discloses a preparation method of a 1650 DEG C-resistant flexible aluminum oxide continuous fiber heat insulation tile, and belongs to the technical field of high-temperature aluminum oxide materials. The 1650 DEG C resistant flexible aluminum oxide continuous fiber heat insulation tile comprises a flexible aluminum oxide heat insulation tile and a surface coating. The heat insulation tile is of a sandwich structure and is prepared by sewing an aluminum oxide continuous fiber cloth surface layer and an aluminum oxide continuous fiber felt middle layer. The coating is composed of a component A filler and a component B radiation agent. The component A is one or more of MoSi2, silicon carbide or silicon boride. And the component B is SiO2 powder, metal silicon powder, silicon carbide fibers and alumina fibers. The thermal insulation tile resistant to the high temperature of 1650 DEG C has the advantages of long-time high temperature resistance, excellent durability, special-shaped forming performance, high radiation performance and moisture resistance; the invention also provides a preparation method with a simple process.
