The invention discloses a high-temperature phase-change heat-insulation composite heat-insulation component and a preparation method thereof. The composite heat-insulation component is formed by alternately combining multiple layers of blocky efficient heat insulation materials and high-temperature phase change composite materials. Quartz fiber cloth or aluminum oxide fiber cloth is used for packaging the composite heat insulation structure. The back temperature and the temperature control time of the high-temperature phase-change heat-insulation composite heat-insulation component are adjusted by adjusting the thicknesses of the efficient heat insulation material and the high-temperature phase change composite material and the phase change temperature of the high-temperature phase changecomposite material, the back temperature of the composite heat-insulation component can be controlled to be smaller than or equal to 200 DEG C, and the temperature control time is longer than or equalto 2000s. The high-temperature phase-change thermal-insulation composite thermal-insulation component is simple in preparation process and excellent in thermal protection performance, can be used forthermal protection of aircraft structures and instruments such as missile-rocket ships and the like, improves the thermal protection capability, and has potential wide application prospects in the civil field.
