Multi-layer thermal insulation material with heat storage and anti-radiation structure and preparation method for multi-layer thermal insulation layer

The invention discloses a multi-layer thermal insulation material with a heat storage and anti-radiation structure and a preparation method for the multi-layer thermal insulation layer. The thermal insulation material relates to use of a material with a low heat conduction coefficient, a material with high heat capacity and an anti-radiation material, and the causes of heat loss are comprehensively considered from two aspects of conduction and radiation heat transfer, so that the thin-layer thermal-insulation composite material is prepared in a targeted manner according to the heat loss condition. The method comprises the following steps: 1) using a heat storage material; 2) using a hollow material; and 3) using a metal film material. The multi-layer thermal insulation material with the heat storage and anti-radiation structure can preserve heat for various principles for heat transfer, thereofe, a very good thermal insulation effect can be achieved if the material is relatively thin, and especially, the ther
