Summary:The invention discloses a preparation method of a high-silica compound ceramic heat insulating product. The method comprises the following steps of: (1) boiling high-silica fiber braided bodies with water in sequence, drying, introducing oxygen into a vacuum container for baking, washing with acid, washing with water and drying; (2) soaking the high-silica fiber braided bodies in silica sol for 30-60 minutes, and controlling the density of the silica sol at 1.12-1.16 g/cm ; (3) vibrating the silica sol, continually soaking the high-silica fiber braided bodies for 30-60 minutes, taking out, and drying for 20-40 hours; (4) repeatedly treating the high-silica fiber braided bodies according to the step (2) and step (3) for 2-6 times; (5) performing thermal treatment on the high-silica fiberbraided bodies at the temperature of 300-700 DEG C till the high-silica fiber braided bodies become half-ceramic rough blanks; and (6) processing the rough blanks to the needed product size to obtainthe high-silica compound cer
