Heat insulation tile based on resin-based carbon foam and preparation method therefor

The invention discloses a heat insulation tile based on resin-based carbon foam and a preparation method therefor. The heat insulation tile structurally comprises a heat insulation layer, an outer panel, a sealing plate and a bottom panel; the heat insulation layer has a heat insulation function; the outer panel plays a role in surface enhancement and protects an internal structure from airflow erosion and surface impact damage; the sealing plate and the bottom panel are a layer of compact high-temperature-resistant thin plates and tightly wrap the heat insulation layer together to prevent oxygen from entering and avoid carbon foam oxidation; and the bottom panel is connected with the main structure. The thermal insulation layer has the density and thermal conductivity similar to those of thermal insulation ceramic, but is higher in modulus and strength and higher in long-term use temperature; by designing the outer panel, the sealing plate and the bottom panel, the problem that the resin-based carbon foam is
