This invention discloses a high-temperature resistant, heat-insulating, ceramizable fire-resistant sealing adhesive and its preparation method. The fire-resistant sealing adhesive comprises the following raw materials: base adhesive, dimethyl silicone oil, flame retardant, composite ceramic powder, additive filler, flux, silane coupling agent, crosslinking agent, functional filler, and catalyst. The functional filler is composed of fumed silica, high-temperature resistant aerogel powder, and silicon carbide powder, with a mass ratio of 40-50:20-30:20-30. Through the specific selection of multi-stage filler compounding, this invention achieves a balance between room-temperature performance and the high-temperature ceramization process that is unattainable in existing technologies. Its flame retardant rating can reach V0, its fire resistance limit is greater than 4.5 hours, and during the burning process, the highest temperature on the unexposed surface does not exceed 110°C.
