Abstract: The thermal insulation and protection principles of infrared thermal reflective coating and its research progress are reviewed. Nano-ceramic hollow bead application on infrared thermal reflective coatings is mainly introduced. Fabricating the composite infrared thermal reflective coating by means of the sol-gel method is presented and the improvement of the thermal insulating performance of fibrous thermal insulation by nano-composite infrared thermal reflective coating is introduced.
